Honglian type-cytoplasmic male sterility(HL-CMS)is caused by the inter-communication between the nucleus and mitochondria.However,the mechanisms by which sterility genes regulate metabolic alterations and changes in mitochondrial morphology in the pollen of HL-CMS remain unclear.In this study,we compared the morphological differences between the pollen of the male sterile line YA and the near-isogenic line NIL-Rf6 using hematoxylin-eosin staining and 4ʹ,6-diamidino-2-phenylindole(DAPI)staining.HL-CMS is characterized by gametophytic sterility,where the aborted pollen grains are empty,and the tapetal layer remains intact.Transmission electron microscopy was employed to observe mitochondrial morphological changes at the microspore stage,revealing significant mitochondrial alterations,characterized by the formation of'large spherical mitochondria',occurred at the binucleate stage in the YA line.Additionally,metabolomics analysis revealed decreased levels of metabolites associated with the carbohydrate and flavonoid pathways.Notably,the decrease in flavonoids was found to contribute to an elevation in reactive oxygen species(ROS)levels.Therefore,we propose a model in which rice fertility is modulated by the levels of pollen carbohydrates and flavonoid metabolites,with impaired mitochondrial energy production and reduced flavonoid biosynthesis as the main causes of ROS accumulation and pollen abortion in rice. 展开更多

Objective:The objective of this study was to determine the level of methotrexate(MTX)toxicity in the intestines of mice and to evaluate the protective effect of probiotics composed of Streptococcus,Bifidobacterium,and Lactobacillus species on intestinal cells during MTX treatment.Methods:Mice were divided into three groups:control,MTX group(received MTX injections),and MTX+probiotics group(received MTX injections along with a diet containing probiotics).Morphological and histological changes,the level of mitochondrial DNA(mtDNA)damage,the level of lipid peroxidation products,and gene expression in the mice’s small intestine were assessed.Results:We demonstrated that intraperitoneal MTX injections significantly increased mtDNA damage in the liver(p<0.001),small intestine(p<0.001),and blood of mice(p<0.01).MTX elevated the quantity of lipid peroxidation products in the liver and small intestine,indicating its strong prooxidative properties.MTX induced structural changes in the mice’s intestines,characterized by leukocytic infiltration of tissues.Probiotic therapy in mice partially mitigated the morphological and histological changes in the small intestine induced by MTX,reduced oxidative stress,and promoted increased expression of quinone oxidoreductase 1(Nqo1),which participates in both cell protection against oxidative stress and drug/xenobiotic detoxification.Probiotics prevented the upregulation of the proinflammatory cytokine IL-1b in the small intestine and induced increased expression of genes associated with the Nuclear factor erythroid 2-related factor 2/Antioxidant response element(Nrf2/ARE)pathway,an important mechanism of cell protection.Conclusions:Probiotics can be considered an effective approach to reducing the toxicity of MTX during psoriasis or cancer treatment. 展开更多

Atherosclerotic coronary artery disease(CAD) comprises a broad spectrum of clinical entities that include asymptomatic subclinical atherosclerosis and its clinical complications, such as angina pectoris, myocardial infarction(MI) and sudden cardiac death. CAD continues to be the leading cause of death in industrialized society. The long-recognized familial clustering of CAD suggests that genetics plays a central role in its development, with the heritability of CAD and MI estimated at approximately 50% to 60%. Understanding the genetic architecture of CAD and MI has proven to be difficult and costly due to the heterogeneity of clinical CAD and the underlying multi-decade complex pathophysiological processes that involve both genetic and environmental interactions. This review describes the clinical heterogeneity of CAD and MI to clarify the disease spectrum in genetic studies, provides a brief overview of the historical understanding and estimation of the heritability of CAD and MI, recounts major gene discoveries of potential causal mutations in familial CAD and MI, summarizes CAD and MIassociated genetic variants identified using candidate gene approaches and genome-wide association studies(GWAS), and summarizes the current status of the construction and validations of genetic risk scores for lifetime risk prediction and guidance for preventive strategies. Potential protective genetic factors against the development of CAD and MI are also discussed. Finally, GWAS have identified multiple genetic factors associated with an increased risk of in-stent restenosis following stent placement for obstructive CAD. This review will also address genetic factors associated with in-stent restenosis, which may ultimately guide clinical decision-making regarding revascularization strategies for patients with CAD and MI. 展开更多

Inflammatory bowel disease (IBD) is a chronic and heterogeneous intestinal inflammatory disorder. The medical management of IBD aims for long-lasting disease remission to prevent complications and disease progression. Early introduction of immunosuppression forms the mainstay of medical IBD management. Large inter-individual variability in drug responses, in terms of both efficacy and toxicity, leads to high rates of therapeutic failure in the management of IBD. Better patient stratification is needed to maximize patient benefit and minimize the harm caused by adverse events. Pre-treatment pharmacogenetic testing has the potential to optimize drug selection and dose, and to minimize harm caused by adverse drug reactions. In addition, optimizing the use of cheap conventional drugs, and avoiding expensive ineffective drugs, will lead to a significant reduction in costs. Genetic variation in both TPMT and NUDT15, genes involved in thiopurine metabolism, is associated to an increased risk of thiopurine-induced myelosuppression. Moreover, specific HLA haplotypes confer risk to thiopurine-induced pancreatitis and to immunogenicity to tumor necrosis factor-antagonists, respectively. Falling costs and increased availability of genetic tests allow for the incorporation of pre-treatment genetic tests into clinical IBD management guidelines. In this paper, we review clinically useful pharmacogenetic associations for individualized treatment of patients with IBD and discuss the path from identification of a predictive pharmacogenetic marker to implementation into IBD clinical care. 展开更多

AIM To investigate the regulation of Myopalladin(Mypn) and identify its gene network involved in restrictive cardiomyopathy(RCM).METHODS Gene expression values were measured in the heart of a large family of BXD recombinant inbred(RI) mice derived from C57BL/6J and DBA/2J. The proteomics data were collected from Mypn knock-in and knock-out mice. Expression quantitative trait locus(eQ TL) mapping methods and gene enrichment analysis were used to identify Mypn regulation,gene pathway and co-expression networks.RESULTS A wide range of variation was found in expression of Mypn among BXD strains. We identified upstream genetic loci at chromosome 1 and 5 that modulate the expression of Mypn. Candidate genes within these loci include Ncoa2,Vcpip1,Sgk3,and Lgi2. We also identified 15 sarcomeric genes interacting with Mypn and constructed the gene network. Two novel members of this network(Syne1 and Myom1) have been confirmed at the protein level. Several members in this network are already known to relate to cardiomyopathy with some novel genes candidates that could be involved in RCM. CONCLUSION Using systematic genetics approach,we constructed Mypn co-expression networks that define the biological process categories within which similarly regulated genes function. Through this strategy we have found several novel genes that interact with Mypn that may play an important role in the development of RCM. 展开更多

Understanding the level of genetic diversity in any population is an important requisite towards strategizing measures for conservation and improvement of stocks. This study focused on the assessment of phylogenetics and molecular divergence of tilapia fish species obtained from two populations (Domita in South-South and Odeda in South-West, Nigeria) using the displacement loop (D-loop) and cytochrome b region of the mitochondrial deoxyribonucleic acid (mtDNA). A total of 28 samples (15 from South-South and 13 from South-West) were used for the genetic analysis. DNA was extracted from the tissue of all the samples using Quik-gDNATM miniPrep kit. The D-loop containing the hypervariable region was sequenced for all samples from the two populations, while cytochrome b (Cyt b) region of mtDNA was only sequenced for samples from South-South population. Chromatograms of the sequences were viewed and edited using Bioedit software. Multiple sequence alignment was carried out using molecular evolutionary genetic analysis (MEGA) software before subsequent genetic analyses. Phylogenetic analysis grouped the samples into two clusters based on population. Also, when the two mitochondrial regions were pooled together, they clustered into two major groups based on mitochondrial regions. Analysis of molecular variance (AMOVA) revealed 37.32% variation within population and 62.68% variation among population with a significant fixation index of 0.627 (p 0.05). The genetic distance inferred between D-loop regions of South-South and South-West populations was 0.243. Maternal lineage analysis revealed that the origin of tilapia fish from both populations could be traced to Oreochromis spirilus and Oreochromis leucostictus based on mitochondrial D-loop region. The findings of this study revealed molecular divergence among the tilapia populations and may serve as pivot information for the genetic improvement of this important species. 展开更多

Sesame(Sesamum indicum L.)is an ancient oilseed crop of the Pedaliaceae family with high oil content and potential health benefits.SHI RELATED SEQUENCE(SRS)proteins are the transcription factors(TFs)specific to plants that contain RING-like zinc finger domain and are associated with the regulation of several physiological and biochemical processes.They also play vital roles in plant growth and development such as root formation,leaf development,floral development,hormone biosynthesis,signal transduction,and biotic and abiotic stress responses.Nevertheless,the SRS gene family was not reported in sesame yet.In this study,identification,molecular characterization,phylogenetic relationship,cis-acting regulatory elements,protein-protein interaction,syntenic relationship,duplication events and expression pattern of SRS genes were analyzed in S.indicum.We identified total six SiSRS genes on seven different linkage groups in the S.indicum genome by comparing with the other species,including the model plant Arabidopsis thaliana.The SiSRS genes showed variation in their structure like2–5 exons and 1–4 introns.Like other species,SiSRS proteins also contained‘RING-like zinc finger'and‘LRP1'domains.Then,the SiSRS genes were clustered into subclasses via phylogenetic analysis with proteins of S.indicum,A.thaliana,and some other plant species.The cis-acting regulatory elements analysis revealed that the promoter region of SiSRS4(SIN_1011561)showed the highest 13 and 16 elements for light-and phytohormone-responses whereas,SiSRS1(SIN_1015187)showed the highest 15 elements for stress-response.The ABREs,or ABA-responsive elements,were found in a maximum of 8 copies in the SiSRS3(SIN 1009100).Moreover,the available RNA-seq based expression of SiSRS genes revealed variation in expression patterns between stress-treated and non-treated samples,especially in drought and salinity conditions in.S.indicum.Two SiSRS genes like SiSRS1(SIN_1015187)and SiSRS5(SIN_1021065),also exhibited variable expression patterns between control vs PEG-treated sesame root samples and three SiSRS genes,including SiSRS1(SIN_1015187),SiSRS2(SIN_1003328)and SiSRS5(SIN_1021065)were responsive to salinity treatments.The present outcomes will encourage more research into the gene expression and functionality analysis of SiSRS genes in S.indicum and other related species. 展开更多

Early blight is one of the most destructive plant diseases, especially in the members of solanaceae family. This disease can reduce yield. Experiment design was a factorial randomized complete design to evaluate the isolate pathogenic Alternaria solani in National Plant Gene Bank of Iran, during 2008-2009. This experiment was conducted with three replications, and the factors include test methods and three lines 9506, 10908-05 and 10908-18 with genotypes of Agria, Casmos and Desiree (susceptible) and Delta (resistant control). Analysis of variance table was based on the area under the disease progress curve, indicating the effects of the experimental methods;genotype and their interactions are significant at the 1% level. In greenhouse evaluation, the symptoms appeared on, the first day. In this method the area under the curve progression was noted in 10 times, but in vitro method, the symptoms of this evaluation appeared on the first or second day. The Evaluation was carried out after inoculation, and was noted 6 times. The results indicate that genotypes and lines are located in four different groups. In this case, line 9506 and Cosmos were quite sensitive to the surface, and Desiree, is located in a sensitive area. Line 10908-18 and Agria, located approximately at the level of resistance, and line 10908-05 and Delta, have been resistant surface. 展开更多

Congenital anomalies of the hand are malformations occurring during the development of the human limb,and present as isolated disorders or as a part of a syndrome.During the last years,molecular analysis techniques have offered increasing knowledge about the molecular basis of hand malformations.Disturbances in the signaling pathways during the development of the upper limb result in malformations of the upper extremity.At present,several genes have been identified as responsible for hand anomalies and other have been recognized as suspect genes related to them.Different and new high throughput methods have been introduced for the identification of the gene mutations.In the current editorial,we summarize concisely the current molecular status of isolated hand genetic disorders and the recent progress in molecular genetics,including the genes related to the disorder.This progress improves the knowledge of these disorders and has implications on genetic counselling and prenatal diagnosis. 展开更多

Maize is cultivated extensively throughout the world and has the highest production among cereals.However,Northern corn leaf blight(NCLB)disease caused by Exherohilum turcicum,is the most devastating limiting factor of maize production.The disease causes immense losses to corn yield if it develops prior or during the tasseling and silking stages of crop development.It has a worldwide distribution and its development is favoured by cool to moderate temperatures with high relative humidity.The prevalence of the disease has increased in recent years and new races of the pathogen have been reported worldwide.The fungus E.turcicum is highly variable in nature.Though different management strategies have proved effective to reduce economic losses from NCLB,the development of varieties with resistance to E.turcicum is the most efficient and inexpensive way for disease management.Qualitative resistance for NCLB governed by Ht genes is a race-specific resistance which leads to a higher level of resistance.However,some Ht genes can easily become ineffective under the high pressure of virulent strains of the pathogen.Hence,it is imperative to understand and examine the consistency of the genomic locations of quantitative trait loci for resistance to NCLB in diverse maize populations.The breeding approaches for pyramiding resistant genes against E.turcicum in maize can impart NCLB resistance under high disease pressure environments.Furthermore,the genome editing approaches like CRISPR-cas9 and RNAi can also prove vital for developing NCLB resistant maize cultivars.As such this review delivers emphasis on the importance and current status of the disease,racial spectrum of the pathogen,genetic nature and breeding approaches for resistance and management strategies of the disease in a sustainable manner. 展开更多

Background Globally,the cultivation of cotton is constrained by its tendency for extended periods of growth.Early maturity plays a potential role in rainfed-based multiple cropping system especially in the current era of climate change.In the current study,a set of 20 diverse Gossypium hirsutum genotypes were evaluated in two crop seasons with three planting densities and assessed for 11 morphological traits related to early maturity.The study aimed to identify genotype(s)that mature rapidly and accomplish well under diverse environmental conditions based on the two robust multivariate techniques called multi-trait stability index(MTSI)and multi-trait genotype-ideotype distance index(MGIDI).Results MTSI analysis revealed that out of the 20 genotypes,three genotypes,viz.,NNDC-30,A-2,and S-32 accomplished well in terms of early maturity traits in two seasons.Furthermore,three genotypes were selected using MGIDI method for each planting densities with a selection intensity of 15%.The strengths and weaknesses of the genotypes selected based on MGIDI method highlighted that the breeders could focus on developing early-maturing genotypes with specific traits such as days to first flower and boll opening.The selected genotypes exhibited positive genetic gains for traits related to earliness and a successful harvest during the first and second pickings.However,there were negative gains for traits related to flowering and boll opening.Conclusion The study identified three genotypes exhibiting early maturity and accomplished well under different planting densities.The multivariate methods(MTSI and MGIDI)serve as novel approaches for selecting desired genotypes in plant breeding programs,especially across various growing environments.These methods offer exclusive benefits and can easily construe and minimize multicollinearity issues. 展开更多

Cytochromes P450(CYPs)play a prominent role in catalyzing phase I xenobiotic biotransformation and account for about 75%of the total metabolism of commercially available drugs,including chemotherapeutics.The gene expression and enzyme activity of CYPs are variable between individuals,which subsequently leads to different patterns of susceptibility to carcinogenesis by genotoxic xenobiotics,as well as differences in the efficacy and toxicity of clinically used drugs.This research aimed to examine the presence of the CYP2B6*9 polymorphism and its possible association with the incidence of B-CLL in Egyptian patients,as well as the clinical outcome after receiving cyclophosphamide chemotherapy.DNA was isolated from whole blood samples of 100 de novo B-CLL cases and also from 100 sex-and age-matched healthy individuals.The presence of the CYP2B6*9(G516T)polymorphism was examined by PCR-based allele specific amplification(ASA).Patients were further indicated for receiving chemotherapy,and then they were followed up.The CYP2B6*9 variant indicated a statistically significant higher risk of B-CLL under different genetic models,comprising allelic(T-allele vs.G-allele,OR=4.8,p<0.001)and dominant(GT+TT vs.GG,OR=5.4,p<0.001)models.Following cyclophosphamide chemotherapy,we found that the patients with variant genotypes(GT+TT)were less likely to achieve remission compared to those with the wild-type genotype(GG),with a response percentage of(37.5%vs.83%,respectively).In conclusion,our findings showed that the CYP2B6*9(G516T)polymorphism is associated with B-CLL susceptibility among Egyptian patients.This variant greatly affected the clinical outcome and can serve as a good therapeutic marker in predicting response to cyclophosphamide treatment. 展开更多

Background:Panax notoginseng(PNE)is a prominent traditional Chinese medicine with extensive beneficial effects on the immune system.However,the precise mechanism of PNE in treating inflammatory bowel disease(IBD)remains unclear.Methods:We first used an extensive metabolomics approach utilizing UPLC-ESI-Q TRAP-MS/MS to identify the metabolite components of PNE aqueous extract.Moreover,the mechanism of PNE in treating IBD was investigated through in silico analysis including RNA-seq analysis,Network pharmacology and Molecular docking.Then a Drosophila toxin-induced intestinal inflammation model was employed to investigate further.Results:A total of 1,543 metabolites of PNE aqueous extract were characterized using UPLC-ESI-Q TRAP-MS/MS.In silico analyses showed that 97 IBD hub targets were targeted by 21 PNE ingredients.Kyoto Encyclopedia of Genes and Genomes results indicated that PNE may play an anti-IBD role through the Mitogen-activated protein kinase(MAPK)signaling pathway and other immune-related signaling pathways.Moreover,11 top hits compounds of PNE show a good affinity binding to IBD targets.The experimental results demonstrated that PNE can effectively improve the survival rate of adult Drosophila while also inhibit the excessive proliferation and differentiation of intestinal stem cells induced by sodium dodecyl sulfate.Furthermore,PNE notably lower the epithelial cell mortality,the accumulation of reactive oxygen species and the activation of oxidative stress-associated jun-Nterminal kinase(JNK)pathway.Conclusion:Our data suggests that PNE aqueous extract has a significant protective impact on the intestinal homeostasis of Drosophila.These findings establish a basis for utilizing PNE in clinical investigations and managing IBD. 展开更多

Country bean, Lablab purpureus (L.) is considered one of the most important leguminous crops, but their cultivation under drought stress condition encounters challenges. In this study, an experiment has been conducted among 30 genotypes under drought condition to explore morphological diversity of qualitative and quantitative, biochemical, molecular analysis. The study identified significant variations in eight traits among the genotypes examined, with phenotypic variance exceeding genotypic variance, indicating both genetic and environmental influences. High heritability and genetic advance were observed in primary, secondary, and tertiary branch lengths, suggesting these traits are likely controlled by additive gene effects, making them effective targets for selection. Principal component analysis identified three components that made a substantial contribution, accounting for approximately 73.06% of the overall quantitative variations. Among the quantitative traits, the highest coefficient of variation (CV%) has been found in number of flowers (55.05%). While number of primary branches, primary branch length, number of secondary branches, secondary branch length, number of tertiary branches, tertiary branch length has individually more than 20% of CV%. The genotypes have been grouped into three clusters based on quantitative traits. Analysis of protein reveals that the genotypes of DS28 and DS29 have higher protein content than other genotypes. Dehydrogenase responsive genotypes have been found on DS28 and DS29 from the molecular analysis. The results suggest that the genotypes DS28 and DS29 could contribute as genetic resource of high protein content and DREB responsive, and the eight quantitative traits of 30 genotypes could be used for further breeding programme. 展开更多
