Liver cancer is a prevalent malignant cancer,ranking third in terms of mortality rate.Metastasis and recurrence primarily contribute to the high mortality rate of liver cancer.Hepatocellular carcinoma(HCC)has low expression of focal adhesion kinase(FAK),which increases the risk of metastasis and recurrence.Nevertheless,the efficacy of FAK phosphorylation inhibitors is currently limited.Thus,investigating the mechanisms by which FAK affects HCC metastasis to develop targeted therapies for FAK may present a novel strategy to inhibit HCC metastasis.This study examined the correlation between FAK expression and the prognosis of HCC.Additionally,we explored the impact of FAK degradation on HCC metastasis through wound healing experiments,transwell invasion experiments,and a xenograft tumor model.The expression of proteins related to epithelial-mesenchymal transition(EMT)was measured to elucidate the underlying mechanisms.The results showed that FAK PROTAC can degrade FAK,inhibit the migration and invasion of HCC cells in vitro,and notably decrease the lung metastasis of HCC in vivo.Increased expression of E-cadherin and decreased expression of vimentin indicated that EMT was inhibited.Consequently,degradation of FAK through FAK PROTAC effectively suppressed liver cancer metastasis,holding significant clinical implications for treating liver cancer and developing innovative anti-neoplastic drugs. 展开更多

Background:The role of TROVE domain family member 2(TROVE2)has been well-demonstrated in autoimmune diseases;however,its involvement in liver cancer remains unclear.Therefore,this study aimed to explore the biological function and clinical significance of TROVE2 in hepatocellular carcinoma(HCC).Methods:The expression level of TROVE2 was analyzed in HCC and paired adjacent tissue samples using real-time reverse transcription-quantitative polymerase chain reaction.The impact of TROVE2 on migration and invasion in HCC cells was analyzed through Transwell assays and Western blotting.High-throughput transcriptome sequencing and bioinformatics analyses were performed to identify downstream target genes.Back-complementation experiments were employed to verify the influence of downstream proteins on TROVE2-induced invasion and migration of HCC cells.Results:TROVE2 exhibited significant overexpression in liver cancer tissue,correlating with shorter overall survival.Overexpression of TROVE2 facilitated the invasion,metastasis,and epithelial-mesenchymal transition(EMT)process of HCC cells,whereas TROVE2 knockdown restrained migration,invasion,and EMT in these cells.Transcriptome sequencing and bioinformatics analysis identified heparanase(HPSE)as a downstreamtarget protein of TROVE2.Subsequent back-complementation experiments provided evidence that HPSE overexpression promoted TROVE2-mediated prometastasis effects.Moreover,the study revealed that TROVE2 was capable of regulating the EMT pathway through GSK-3βphosphorylation.Conclusions:TROVE2 facilitated the invasion,migration,and EMT process ofHCC cells through phosphorylation of the HPSE/GSK-3βaxis,indicating its significance as an important protein in tumor progression. 展开更多

Current treatments for advanced hepatocellular carcinoma(HCC)have limited success in improving patients’quality of life and prolonging life expectancy.The clinical need for more efficient and safe therapies has contributed to the exploration of emerging strategies.Recently,there has been increased interest in oncolytic viruses(OVs)as a therapeutic modality for HCC.OVs undergo selective replication in cancerous tissues and kill tumor cells.Strikingly,pexastimogene devacirepvec(Pexa-Vec)was granted an orphan drug status in HCC by the U.S.Food and Drug Administration(FDA)in 2013.Meanwhile,dozens of OVs are being tested in HCC-directed clinical and preclinical trials.In this review,the pathogenesis and current therapies of HCC are outlined.Next,we summarize multiple OVs as single therapeutic agents for the treatment of HCC,which have demonstrated certain efficacy and lowtoxicity.Emerging carrier cell-,bioengineered cell mimetic-or nonbiological vehicle-mediated OV intravenous delivery systems in HCC therapy are described.In addition,we highlight the combination treatments between oncolytic virotherapy and other modalities.Finally,the clinical challenges and prospects of OV-based biotherapy are discussed,with the aim of continuing to develop a fascinating approach in HCC patients. 展开更多

Hepatocellular carcinoma(HCC)is the most common malignancy of the liver,posing a significant threat to public health.Although liver transplantation(LT)is an effective treatment for HCC,ischemia–reperfusion(I/R)injury,transplant rejection,and complications after LT can greatly reduce its effectiveness.In recent years,transplant oncology has come into being,a comprehensive discipline formed by the intersection and integration of surgery,oncology,immunology,and other related disciplines.Gut microbiota,an emerging field of research,also plays a crucial role.Through the microbiome–gut–liver axis,the gut microbiota has an impact on the onset and progression of HCC as well as LT.This review summarizes the mechanisms by which the gut microbiota affects HCC and its bidirectional interactions with chronic liver disease that can develop into HCC as well as the diagnostic and prognostic value of the gut microbiota in HCC.In addition,gut microbiota alterations after LT were reviewed,and the relationship between the gut microbiota and liver I/R injury,the efficacy of immunosuppressive drugs used,and complications after LT were discussed.In the era of LT oncology,the role of the gut microbiota in HCC and LT should be emphasized,which can provide new insights into the management of HCC and LT via gut microbiota modulation. 展开更多

It develops in 90% of cases of cirrhosis, more rarely on chronic non-cirrhotic liver disease, and exceptionally in a healthy liver. This study aimed to investigate the clinical aspects of Hepatocellular Carcinoma (HCC). It was a retrospective descriptive study covering 10 years, focusing on HCC cases seen in outpatient and inpatient settings at the Internal Medicine Department. We recorded 153 cases out of 7021 patient records, resulting in a hospital frequency of 2.17%. The male-to-female ratio was 3.5. The mean age was 52.37 ± 14.34 years. The most common presenting complaint was pain in 16.3% of cases. A history of jaundice was found in 25.5% of cases. Alcohol consumption was observed in 15.38% of cases. The main physical sign found was hepatomegaly in 76% of cases. HBsAg was positive in 33.3% of cases. Alpha-fetoprotein levels were above 400 IU/ml in 50.81% of cases. Patients classified as CHILD PUGH A represented 39.72% of cases. Abdominal ultrasound revealed portal thrombosis associated with heterogeneous multinodular hepatomegaly in 11% of cases. Cytology confirmed HCC in four out of six patients who underwent the examination. We recorded 63 deaths out of 111 hospitalized patients. Complications included encephalopathy, hematemesis, and ascites in 48 patients. Hepatocellular carcinoma remains a significant public health issue. Its predominance in men and its occurrence in adults with factors such as viral infections and ethylism mean that prevention of this pathology could greatly reduce its incidence. 展开更多

Hepatocellular carcinoma(HCC)is the most common primary liver malignancy and causes one third of cancer related deaths world-wide.Approximately one third of patients with HCC are eligible for curative treatments that include hepatic resection,liver transplantation or imaging guided tumor ablation.Recurrence rates after primary therapy depends on tumor biology and pre-treatment tumor burden with early recurrence rates ranging from 30%-80%following surgical resection and ablation.HCC recurs in over ten percent following liver transplantation for HCC.Treatment modalities for tumor recurrence following resection and ablation include repeat liver resection,salvage liver transplantation,locoregional therapies,and systemic chemotherapy/immunotherapy.Locoregional and immune mediated therapies are limited for patients with tumor recurrence following liver transplantation given potential immune related allograft rejection.Given the high HCC recurrence rates after primary tumor treatment,it is imperative for the clinician to review the appropriate treatment strategy for this disease entity.This article will review the current literature regarding HCC recurrence after primary curative therapies and will discuss the relevant future trends in the HCC field. 展开更多

Objective Xiaoaiping (XAP) is a traditional Chinese medicine that is a commonly used as an anticancerdrug in clinical practice owing to its high efficiency and low toxicity. Specifically, XAP can effectively inhibitthe growth of hepatocellular carcinoma (HCC). Alpha-fetoprotein (AFP) is a key HCC diagnostic marker andis closely related to certain malignant cytological behaviors of HCC. However, whether AFP expression andXAP treatment are related to the invasion and metastasis of HCC remains unclear. In the present study, weaimed to evaluate the effects and underlying mechanism of XAP on the invasion and metastasis of HCC..Methods Using a cell scratch assay, Transwell technology, and western blotting we detected the differentinvasion and metastatic abilities of Hep3B cells in XAP treatment and blank control groups. This allowedcomparison of the invasion and metastatic abilities of Hep3B cells with differing levels of AFP expression.AFP mRNA sequencing technology was used to analyze the mechanism of tumor invasion and metastasisassociated with AFP and XAP treatment.Results Cell invasion and metastasis abilities in the XAP group were significantly lower than those in thecontrol group (P < 0.05). Additionally, compared to the control group, the expression of AFP significantlydecreased after XAP treatment (P < 0.05). The ability of Hep3B cells to invade and metastasize waspromoted when AFP expression was up-regulated, whereas it was inhibited when AFP was silenced. XAPinjection and AFP regulate the invasion and metastatic ability of HCC by affecting matrix metalloproteinases(MMPs).Conclusion XAP injection inhibits the invasion and metastatic ability of HCC by influencing the expressionof AFP;additionally, this inhibition of AFP is achieved by affecting MMPs. 展开更多
