Molecular determinants of response to 5-fluorouracil-based chemotherapy in colorectal cancer: The undisputable role of microribonucleic acids

5-flurouracil(5-FU)-based chemotherapy is the main pharmacological therapy for advanced colorectal cancer(CRC).Despite significant progress in the treatment of CRC during the last decades,5-FU drug resistance remains the most important cause of failure in CRC therapy.Resistance to 5-FU is a complex and multistep process.Different mechanisms including microsatellite instability,increased expression level of key enzyme thymidylate synthase and its polymorphism,increased level of 5-FU-activating enzymes and mutation of TP53 are proposed as the main determinants of resistance to 5-FU in CRC cells.Recently,microribonucleic acids(miRNA)and their alterations were found to have a crucial role in 5-FU resistance.In this regard,the miRNA-mediated mechanisms of 5-FU drug resistance reside among the new fields of pharmacogenetics of CRC drug response that has not been completely discovered.Identification of the biological markers that are related to response to 5-FU-based chemotherapy is an emerging field of precision medicine.This approach will have an important role in defining those patients who are most likely to benefit from 5-FU-based chemotherapy in the future.Thereby,the identification of 5-FU drug resistance mechanisms is an essential step to predict and eventually overcome resistance.In the present comprehensive review,we will summarize the latest knowledge regarding the molecular determinants of response to 5-FU-based chemotherapy in CRC by emphasizing the role of miRNAs.

Rare manifestation of familial vitreous amyloidosis caused by Gly103Arg transthyretin

AIM:To identify and analyze the genotype of the patients with special ocular manifestations of familial vitreous amyloidosis(FVA)in a Chinese Han family.METHODS:Pars plana vitrectomy(PPV)surgery was performed on a 52-year-old Chinese woman presented with vitreous amyloidosis and progressive visual impairment,without evidence of cardiac,renal,gastrointestinal,central nervous system or peripheral nervous system dysfunction.During the surgery,the patient presented with a gray-white dense and thick cotton woollike change in the vitreous body,accompanied by complete retinal detachment.Additionally,hard,free and movable yellow-white deposits were observed in the posterior pole and surrounding retina,the vitreous and subretinal deposits were examined by Congo red staining and immunohistochemical pathological examination,and whole exome sequencing was performed on blood samples from the patient and her cousin.RESULTS:During the operation,it was discovered that there was a complete detachment of the retina and a significant amount of hard,free-floating yellow-white deposits were observed beneath the posterior pole and surrounding retina.This is an exceedingly rare ocular manifestation.Pathological examination of the vitreous and subretinal deposit specimens revealed positive Congo red staining,as well as elevated vascular endothelial growth factor(VEGF)expression in vascular endothelial cells within the sediment specimens upon immunohistochemical examination.The patient and her cousin both exhibited a heterozygous mutation in Glyl03Arg within the transthyretin(TTR)gene,resulting in a substitution of glycine(Gly)at position 103 with arginine(Arg).CONCLUSION:FVA may present with various ocular manifestations,but panretinal detachment is a rare occurrence.In cases where retinal detachment persists for an extended period of time,amyloid deposits may form under the retina through retinal tears,leading to subretinal deposits that can impede retinal reattachment and negatively impact visual prognosis.Elevated levels of VEGF in the eyes of FVA patients may indicate an overexpression state,necessitating careful postoperative follow-up.The heterozygous mutation Gly103Arg may represent a unique pathogenic site in Chinese individuals.

Exosomes in viral infection:Effects for pathogenesis and treatment strategies

Exosomes are small vesicles that carry molecules from one cell to another.They have many features that make them interesting for research,such as their stability,low immunogenicity,size of the nanoscale,toxicity,and selective delivery.Exosomes can also interact with viruses in diverse ways.Emerging research highlights the significant role of exosomes in viral infections,particularly in the context of diseases like COVID-19,HIV,HBV and HCV.Understanding the intricate interplay between exosomes and the human immune system holds great promise for the development of effective antiviral therapies.An important aspect is gaining clarity on how exosomes influence the immune system and enhance viral infectivity through their inherent characteristics.By leveraging the innate properties of exosomes,viruses exploit the machinery involved in exosome biogenesis to set replication,facilitate the spread of infection,and eliminate immune responses.They can either help or hinder viral infection by modulating the immune system.This review summarizes the recent findings on how exosomes mediate viral infection and how they can be used for diagnosis or therapy.This could lead to new clinical applications of exosomes in disease management.

Autophagy in hepatitis C virus-host interactions:Potential roles and therapeutic targets for liver-associated diseases

Autophagy is a lysosome-associated,degradative process that catabolizes cytosolic components to recycle nutrients for further use and maintain cell homeostasis.Hepatitis C virus(HCV)is a major cause of chronic hepatitis,which often leads to end-stage liverassociated diseases and is a significant burden on worldwide public health.Emerging lines of evidence indicate that autophagy plays an important role in promoting the HCV life cycle in host cells.Moreover,the diverse impacts of autophagy on a variety of signaling pathways in HCV-infected cells suggest that the autophagic process is required for balancing HCVhost cell interactions and involved in the pathogenesis of HCV-related liver diseases.However,the detailed molecular mechanism underlying how HCV activates autophagy to benefit viral growth is still enigmatic.Additionally,how the autophagic response contributes to disease progression in HCV-infected cells remains largely unknown.Hence,in this review,we overview the interplay between autophagy and the HCV life cycle and propose possible mechanisms by which autophagy may promote the pathogenesis of HCVassociated chronic liver diseases.Moreover,we outline the related studies on how autophagy interplays with HCV replication and discuss the possible implications of autophagy and viral replication in the progression of HCV-induced liver diseases,e.g.,steatosis and hepatocellular carcinoma.Finally,we explore the potential therapeutics that target autophagy to cure HCV infection and its related liver diseases.

Identify the signature genes for diagnose of uveal melanoma by weight gene co-expression network analysis

AIM: To identify and understand the relationship between co-expression pattern and clinic traits in uveal melanoma, weighted gene co-expression network analysis(WGCNA) is applied to investigate the gene expression levels and patient clinic features. Uveal melanoma is the most common primary eye tumor in adults. Although many studies have identified some important genes and pathways that were relevant to progress of uveal melanoma, the relationship between co-expression and clinic traits in systems level of uveal melanoma is unclear yet. We employ WGCNA to investigate the relationship underlying molecular and phenotype in this study.METHODS: Gene expression profile of uveal melanoma and patient clinic traits were collected from the Gene Expression Omnibus(GEO) database. The gene co-expression is calculated by WGCNA that is the R package software. The package is used to analyze the correlation between pairs of expression levels of genes.The function of the genes were annotated by gene ontology(GO).RESULTS: In this study, we identified four co-expression modules significantly correlated with clinictraits. Module blue positively correlated with radiotherapy treatment. Module purple positively correlates with tumor location(sclera) and negatively correlates with patient age. Module red positively correlates with sclera and negatively correlates with thickness of tumor. Module black positively correlates with the largest tumor diameter(LTD). Additionally, we identified the hug gene(top connectivity with other genes) in each module. The hub gene RPS15 A, PTGDS, CD53 and MSI2 might play a vital role in progress of uveal melanoma.CONCLUSION: From WGCNA analysis and hub gene calculation, we identified RPS15 A, PTGDS, CD53 and MSI2 might be target or diagnosis for uveal melanoma.

Effect of crocin carotenoid on BDNF and CREB gene expression in brain ventral tegmental area of morphine treated rats

Objective: To investigate the effect of crocin carotenoid on BNDF and CREB gene expression in the brain ventral tegmental area(VTA) and the serum level of BDNF in morphine-treated rats compared to control. Methods: In this study, 40 male Wistar rats(200-250 g) were used in 5 experimental groups: 1) non morphine treat rats(control); 2) non morphine-treated rats with 25 mg/kg crocin carotenoid(i.p., for 21 d); 3) morphine treated rats(10 mg/kg twice a day, s.c., 21 d); 4 and 5) morphine-treated rats with 12.5 and 25 mg/kg crocin carotenoid, respectively. By the end of research, BDNF and CREB expression was determined by real-time-PCR method. ELISA analysis was also applied for assessing the serum BDNF level. Results: The data indicated that morphine treatment could cause a significant decrease in BDNF and CREB gene expression(P<0.01 and P<0.001, respectively) in brain VTA as well as serum level of BDNF(P<0.01) in comparison to control group. Treatment with 25 mg/kg crocin carotenoid caused a significant enhancement in BDNF and CREF gene expression(P<0.01 and P<0.05, respectively) and serum level of BDNF(P<0.01) in morphine-treated rats in comparison to morphine-treated group. Conclusions: Regarding to obtained results, crocin carotenoid can inhibit unfavorable effects of morphine on the neural system to some extent through enhancing BDNF and CREB gene expression in brain VTA and serum level of BDNF.

Anti-cancer effects of hydro-alcoholic extract of pericarp of pistachio fruits

Objective:To investigate the cytotoxicity and anti-cancer effects of hydro-alcoholic extract of pistachio pericarp on hepatocellular carcinoma cells(HepG2)and mouse fibroblast L929 cells as normal and control group cell.Methods:MTT assay was performed to investigate the cytotoxicity effects of the extract at 0-4 000μg/mL on the cells after 24 and48 h.The expressions of some genes involved in apoptosis including Bax,Bcl-2 and P53were investigated by real time PCR.Results:Our results showed that after 24 and 48 hours of treatment of cells with this extract,the viability of HepG2 and L929 cells was reduced.Therefore,this extract had the cytotoxicity effect on both cells.The IC_(50) concentration of extract for HepG2 cells after 24 and 48 hours of treatment was 1 500 and 1 000μg/mL and for L929 cells was 2 000 and 1 500μg/mL,respectively.The expressions of Bax and P53 genes were up-regulated after treatment in the HepG2 and L929 cells and the expression of Bcl-2gene was down-regulated after treatment of extract in HepG2 cell.Conclusions:According to the results of MTT assay and real time PCR,this extract can be considered as a potential candidate for use in the production of anti-cancer drugs for the treatment of patients with liver cancer in future.

Synergists action of piperonyl butoxide and S,S,S-tributyl phosphorotrithioate on toxicity of carbamate insecticides against Blattella germanica

Objective: To determine the synergists action of piperonyl butoxide(PBO) and S,S,Stributyl phosphorotrithioate(DEF) on toxicity of carbamate insecticides against Blattella germanica in Tehran city.Methods: In the current study, German cockroach strains were collected from several hospitals and dormitories in Tehran.At the beginning, different concentrations of bendiocarb and carbaryl(insecticides belong to carbamate group) were determined by surface contact on a susceptible strain.Then, the level of susceptibility and type of resistance mechanisms in the collected strains from contaminated sites to the aforementioned insecticides were studied by using PBO and DEF synergists with different insecticide ratios to synergist(1:0, 1:1, 1:2, 1:3).Results: The DEF synergist along with bendiocarb and carbaryl completely eliminated the resistance in all strains but PBO did not completely eliminate the resistance in the strains of Mofid, Alvand, Valiasr hospitals and Shariati dormitory.Generally, the impact of DEF was observed in the removing resistance more than PBO.Conclusions: In most of these strains, resistance to bendiocarb and carbaryl is completely eliminated by DEF, showing a very high role of estraze enzymes in resistance to bendiocarb and carbaryl.But in most strains PBO does not remove the resistance because other mechanisms, such as reduced cuticle penetration and insensitivity to the acetylcholine esterase enzyme, may be involved.

Controversial issues regarding the roles of IL-10 and IFN-γ in active/inactive chronic hepatitis B

According to the important roles played by cytokines in induction of appropriate immune responses against hepatitis B virus(HBV),Dimitropoulou et al have examined the important cytokines in their patients.They showed that the serum levels of interleukin 10(IL-10)and interferon-γ(IFN-γ)were decreased in patients with HBeAg-negative chronic active hepatitis B compared with the inactive hepatitis B virus carriers(Dimitropoulou et al 2013).The controversy can be considered regarding the decreased serum levels of IFN-γin the HBeAg-negative chronic active hepatitis B patients.They concluded that subsequent to decreased expression of IFN-γ,the process of HBV proliferation led to liver diseases.Previous studies stated that HBV is not directly cytopathic for the infected hepatocytes and immune responses are the main reason for destruction of hepatocytes(Chisari et al,2010).Scientists believe that immune responses against HBV are stronger in active forms of chronic HBV infected patients than inactive forms(Zhang et al,2012).Therefore,the findings from Dimitropoulou et al may deserve further attention and discussion.Additionally,downregulation of IL-10 inchronically active hepatitis B infected patients has also confirmed our claim.IL-10 is an anti-inflammatory cytokine and its expression is increased in inactive forms in order to downregulate immune responses(Arababadi et al,2012).Thus,based on the results from Dimitropoulou et al,it can be concluded that increased immune responses in chronically active hepatitis B infected patients are related to declined expression of IL-10 and interestingly IFN-γis not involved in induction of immune responses in these patients.

Polyunsaturated fatty acids and DNA methylation in colorectal cancer

Colorectal cancer(CRC) has been designated a major global problem, especially due to its high prevalence in developed countries. CRC mostly occurs sporadically(75%-80%), and only 20%-25% of patients have a family history.Several processes are involved in the development of CRC such as a combination of genetic and epigenetic alterations. Epigenetic changes, including DNA methylation play a vital role in the progression of CRC. Complex interactions between susceptibility genes and environmental factors, such as a diet and sedentary lifestyle, lead to the development of CRC. Clinical and experimental studies have confirmed the beneficial effects of dietary polyunsaturated fatty acids(PUFAs) in preventing CRC. From a mechanistic viewpoint, it has been suggested that PUFAs are pleiotropic agents that alter chromatin remodeling,membrane structure and downstream cell signaling. Moreover, PUFAs can alter the epigenome via modulation of DNA methylation. In this review, we summarize recent investigations linking PUFAs and DNA methylationassociated CRC risk.

Trigonella foenum-graecum seed extract modulates expression of lipid metabolism-related genes in HepG2 cells

Objective:To investigate anti-dyslipidemic effects of hydroalcoholic fenugreek seed extracts,diosgenin,and 4-OH-Ile on HepG2 cell line.Methods:HepG2 cells were treated with hydroalcoholic fenugreek seed extracts,diosgenin,4-OH-Ile,and orlistat.IC20 was calculated using the MTT method.The cells were then pretreated with IC20 concentrations for 24 and 48 h.Real time PCR was employed to measure expression of liver X receptor alpha(LXR a),sterol regulatory element-binding protein-1 C(SREBP-1 C),acetyl-CoA carboxylase(ACC),fatty acid synthase(FAS),fibroblast growth factor 21(FGF21),peroxisome proliferator-activated receptor gamma(PPAR γ),and lowdensity lipoprotein receptor(LDLR).Results:The results showed that LXR α(P=0.003,P<0.001).,SREBP-1 C(P<0.001,P<0.001),ACC(P=0.002,P=0.006),and FAS(P<0.001,P<0.001)were downregulated significantly,while FGF21(P<0.001,P<0.001),PPAR γ(P=0.004,P<0.001),and LDLR(P<0.001,P<0.001)were upregulated significantly in HepG2 cells treated with the IC20 of hydroalcoholic fenugreek seed extracts,diosgenin,4-OH-Ile,and orlistat in 24 and 48 h,respectively.Conclusions:Hydroalcoholic fenugreek seed extracts,diosgenin,and 4-OH-Ile significantly modulate the expression of some important lipid metabolism related genes,which is similar to orlistat.Trigonella foenum.-graecum seed extract or its derivatives should be further investigated for their dyslipidemia effects and its complications.

The impact of climatic variables on the population dynamics of the main malaria vector, Anopheles stephensi Liston(Diptera: Culicidae), in southern Iran

Objective:To determine the significance of temperature,rainfall and humidity in the seasonal abundance of Anopheles stephensi in southern Iran.Methods:Data on the monthly abundance of Anopheles stephensi larvae and adults were gathered from earlier studies conducted between 2002 and 2019 in malaria prone areas of southeastern Iran.Climatic data for the studied counties were obtained from climatology stations.Generalized estimating equations method was used for cluster correlation of data for each study site in different years.Results:A significant relationship was found between monthly density of adult and larvae of Anopheles stephensi and precipitation,max temperature and mean temperature,both with simple and multiple generalized estimating equations analysis(P<0.05).But when analysis was done with one month lag,only relationship between monthly density of adults and larvae of Anopheles stephensi and max temperature was significant(P<0.05).Conclusions:This study provides a basis for developing multivariate time series models,which can be used to develop improved appropriate epidemic prediction systems for these areas.Long-term entomological study in the studied sites by expert teams is recommended to compare the abundance of malaria vectors in the different areas and their association with climatic variables.

Neural differentiation of choroid plexus epithelial cells:role of human traumatic cerebrospinal fluid

As the key producer of cerebrospinal fluid（CSF）,the choroid plexus（CP） provides a unique protective system in the central nervous system.CSF components are not invariable and they can change based on the pathological conditions of the central nervous system.The purpose of the present study was to assess the effects of non-traumatic and traumatic CSF on the differentiation of multipotent stem-like cells of CP into the neural and/or glial cells.CP epithelial cells were isolated from adult male rats and treated with human non-traumatic and traumatic CSF.Alterations in m RNA expression of Nestin and microtubule-associated protein（MAP2）,as the specific markers of neurogenesis,and astrocyte marker glial fibrillary acidic protein（GFAP） in cultured CP epithelial cells were evaluated using quantitative real-time PCR.The data revealed that treatment with CSF（non-traumatic and traumatic） led to increase in m RNA expression levels of MAP2 and GFAP.Moreover,the expression of Nestin decreased in CP epithelial cells treated with non-traumatic CSF,while treatment with traumatic CSF significantly increased its m RNA level compared to the cells cultured only in DMEM/F12 as control.It seems that CP epithelial cells contain multipotent stem-like cells which are inducible under pathological conditions including exposure to traumatic CSF because of its compositions.

病毒类载体临床前和临床试验中的剂量反应与调控

The objective for human gene therapy is to express exogenous DNA at the targeting cells or nearby to produce a practical and efficient therapeutic dosage at an appropriate time (quantitative pharmacology) with a safe manner. However, the use of genetic material as therapeutic agents has produced many novel and challenging obstacles that remain to be overcome. The obstacles include the formulation or packaging of the DNA, elements and construct of in vivo delivery system, penetration of biological barriers, DNA elimination within the cell and from the tissue compartments of the whole body, control of product expression and overt toxicity. Furthermore, the dose response and control of viral vectors can also be affected by viral serotypes, tissue tropisms, cell targeting, drug regulation, injection route, age and sex, etc. This review discusses the quantitative pharmacological control and effect of current viral vector based preclinical and clinical therapy.

Isolation, distribution and evaluation of cytotoxic and antioxidant activity of cultivable actinobacteria from the Oman Sea sediments

Screening bioactive natural products from bacteria is a determinative step in the drug discovery programs. The present study aim to isolate actinobacteria from the Oman Sea sediments for determining the effects of different culture media and treatments on the yield of the isolation process, and measure the DPPH radical scavenging and Artemia cytotoxic activity of culture extracts of the actinobacterial isolates. A total of 290 actinobacterial isolates were collected from 14 sediment samples. Heat treatment(40.68%) and M4 medium(29.31%) exhibited the maximum isolation rates of actinobacteria. Streptomyces isolates were dominantly distributed in all of the investigated stations according to 16 S rRNA gene sequencing. The distribution pattern of Streptomyces followed a depth-dependent frequency trend, whereas the members of rare genera including Micromonospora, Nocardia Actinoplanes, Nocardiopsis, Saccharopolyspora and Crossiella were distributed in deeper stations. Approximately,25% of the examined isolates could scavenge 90% of 10^–4 mol/L DPPH solutions at 1 250 μg/mL final concentration of their ethyl acetate culture extracts. Furthermore, the most potent extracts could scavenge DPPH radicals with IC50 ranges from 356.8 to 566.4 μg/mL. Brine shrimp cytotoxicity tests showed that 38.88% of the examined culture extracts exhibited LC50 lower than 1 000 μg/mL against the Artemia cells. Moreover, the most potent culture extracts exhibited LC50 range from 335.4 to 534.4 μg/mL. Phylogenetic analysis by 16 S rRNA gene sequence revealed that the OS 005, OS 263 and OS 157 closely related to Streptomyces djakartensis, Streptomyces olivaceus and Nocardiopsis dassonvillei respectively. These results suggested the widespread distribution of the antioxidant and cytotoxic producing actinobacteria in the Oman Sea sediments, which could be considered as promising candidates for the discovery of microbial bioactive compounds.

Opium withdrawal and some blood biochemical factors in addicts' individuals

Objective: One of the common misinterpretation be- liefs in some societies (especially eastern communities) is the using of opium can reduce serum glucose and lipids. Opium is a derivative from a plant family called Papaveracea and contains almost 80 types of alkaloids. Drug addiction causes physiological dependency and its withdrawal lead to some disorders. The aim of this study was to determine the effects of opium consumption and its withdrawal on some blood biochemical factors in addicted people. Methods: We enrolled fifty-six opium addicted people according to the especial criteria to this study. Biochemical blood parameter levels such as fasting blood sugar (FBS), urea, Creatinine (Cr), Aspartate transaminase (AST), Alanine transaminase (ALT) and Alkaline phosphatase (ALP) enzymes levels were measured and urine analysis was also performed before and 3 months after withdrawal. Data were analyzed by using SPSS software version 18 and a P < 0.05 was considered as significant. Results: our finding showed that opium withdrawal reduces FBS and increases AST but these changes were not significant. Nevertheless opium withdrawal significantly increased blood urea level (P < 0.0001). We didn’t find any significant difference in Cr, ALP, AST and Urea specific gravity (SG). Conclusion: According to the results of the current study we can concluded that opium increases FBS, which is in contrast to the most previous studies and withdrawal has opposite effects.

Glycerophospholipids pathways and chromosomal instability in gastric cancer: Global lipidomics analysis

BACKGROUND Based on the breakthrough of genomics analysis, The Cancer Genome Atlas Research Group recently proposed an integrative genomic analysis, dividing gastric cancer(GC) into four subtypes, characterized by the chromosomal instability(CIN) status. However, the CIN status of GC is still vaguely characterized and lacking the valuable easy-to-use CIN markers to diagnosis in molecular and histological detection.AIM To explore the associations of CIN with downstream lipidomics profiles.METHODS We collected cancerous and noncancerous tissue samples from 18 patients with GC; the samples were divided into CIN and non-CIN types based on the system of The Cancer Genome Atlas Research Group and 409 sequenced oncogenes and tumor suppressor genes. We identified the lipidomics profiles of the GC samples and samples of their adjacent noncancerous tissues by using liquid chromatography–mass spectrometry. Furthermore, we selected leading metabolites based on variable importance in projection scores of > 1.0 and P <0.05.RESULTS Twelve men and six women participated in this study; the participants had a median age of 67.5 years(range, 52–87 years) and were divided into CIN(n = 9)and non-CIN(n = 9) groups. The GC samples exhibited distinct profiles of lysophosphocholine, phosphocholine, phosphatidylethanolamine,phosphatidylinositol, phosphoserine, sphingomyelin, ceramide, and triglycerides compared with their adjacent noncancerous tissues. The glycerophospholipid levels(phosphocholine, phosphatidylethanolamine, and phosphatidylinositol)were 1.4-to 2.3-times higher in the CIN group compared with the non-CIN group(P < 0.05). Alterations in the glycerolipid and glycerophospholipid pathways indicated progression of GC toward CIN.CONCLUSION The lipidomics profiles of GC samples were distinct from those of their adjacent noncancerous tissues. CIN status of GC is primarily associated with downstream lipidomics in the glycerophospholipid pathway.
