Hepatitis B e antigen (HBeAg) seropositivity during the natural history of chronic hepatitis B (CHB) is known to coincide with significant increases in serum and intrahepatic HBV DNA levels. However, the precise underlying mechanism remains unclear. In this study, we found that PreC (HBeAg precursor) genetic ablation leads to reduced viral replicat...
The treatment of hepatocellular carcinoma (HCC) has been dominated by multikinase inhibitors for more than a decade. However, drug resistance can severely restrict the efficacy of these drugs. Using CRISPR/CAS9 genome library screening, we evaluated Kelch-like ECH-associated protein 1 (KEAP1) as a key regulator of sorafenib's susceptibility in HCC....
Hepatocellular carcinoma (HCC) is a deadly tumor with high heterogeneity. Aerobic glycolysis is a common indicator of tumor growth and plays a key role in tumorigenesis. Heterogeneity in distinct metabolic pathways can be used to stratify HCC into clinically relevant subgroups, but these have not yet been well-established. In this study, we constru...
Background & aims:
Identifying novel and actional targets in hepatocellular carcinoma (HCC) remains an unmet medical need. TAK1 was originally identified as a TGF-β-activated kinase and was further proved to phosphorylate and activate numerous downstream targets and promote cancer progression. However, the role of TAK1 in developed HCC progression...
Background
Identifying novel and actional targets in hepatocellular carcinoma (HCC) remains an unmet medical need. TAK1 was originally identified as a TGF-β-activated kinase and was further proved to phosphorylate and activate numerous downstream targets and promote cancer progression. Although TAK1 depletion leads to early onset of hepatocarcinoge...
Hepatocellular carcinoma (HCC) is one of most common cancers worldwide, however, the treatment for advanced HCC remains unsatisfactory. We focused on the function of the androgen receptor (AR) in HCC and tried to find new treatment strategy based on antiandrogen enzalutamide (Enz). Here, we found that olaparib, a FDA‐approved PARP inhibitor, could...
Hepatocellular carcinoma (HCC) is one of most common malignant tumors worldwide, however, the treatment for advanced HCC remains unsatisfactory. Here we found that Olaparib, a FDA approved PARP inhibitor, could enhance the cytotoxicity in HCC cells with a lower BRCA1 expression, and suppressing the AR with either Enz or AR-shRNA could further incre...

Mesenchymal stem cells (MSCs) appear to be a potential vehicle for anticancer drugs due to their excellent tumor tropism ability. However, the interactions between MSCs and hepatocellular carcinoma (HCC) are quite controversial and the underlying mechanisms are ambiguous. In this study, an investigation was conducted into the effect of human MSCs (...
About 257 million people with chronic infection of hepatitis B virus (HBV) worldwide are at high risk of developing terminal liver diseases. Reactivation of virus replication has been frequently reported in those patient populations receiving imatinib (an Abl kinase inhibitor) or bortezomib (a proteasome inhibitor) to treat concurrent diseases, but...
Early studies indicated that the androgen receptor (AR) might play key roles to impact hepatocellular carcinoma (HCC) progression at different stages. Its linkage to hypoxia, a condition that occurs frequently during the HCC progression, however, remains unclear. Here we found that AR/miR-520f-3p/SOX9 signaling is involved in altering HCC cells sen...
Background
Pancreatic neuroendocrine tumor (PNET) comprises 1–2% of all pancreatic tumors, but its incidence is increasing. Although many studies have investigated the correlation between cytokeratin 19 (CK-19) and PNET, the prognostic significance of CK-19 expression in PNET is inconclusive.
Methods
Eligible studies were retrieved from Pubmed, El...
Transcription from chromosomes is regulated by posttranslational modifications to histones, such as methylation and ubiquitination. Monoubiquitination of histones H2A and H2B influences H3 methylation to reinforce the activation or repression of gene expression. Here, we provide evidence that H3 polyubiquitination represses transcription of fetal a...
Exosomes are small vesicles that were initially thought to be a mechanism for discarding unneeded membrane proteins from reticulocytes. Their mediation of intercellular communication appears to be associated with several biological functions. Current studies have shown that most mammalian cells undergo the process of exosome formation and utilize e...
Sorafenib is a multikinase inhibitor approved as the first line treatment for late stage hepatocellular carcinoma (HCC). Due to its significant variation in clinical benefits among patients, defining prognostic biomarkers for sorafenib sensitivity in HCC would allow targeted treatment. Phosphorylated extracellular signaling-regulated kinase (pERK)...
Background:
Laparoscopic caudate hepatectomy, which is a challenging procedure, has been reported sporadically. However, there is no standardized surgical technique, and the safety and feasibility of this procedure remain controversial.
Materials and methods:
A left-sided, purely laparoscopic approach for anatomic caudate hepatectomy was used fo...
Hepatocellular carcinoma (HCC) is one of the most common and lethal human cancers. Recently, exome sequencing has revealed that mutation of ARID1A is frequent in HCC. Herein, we determined the clinicopathologic significance of ARID1A expression in HCC. We detected the level of mRNA and protein expression of ARID1A in 12 paired HCC tumors and adjace...
Sorafenib, an orally-available kinase inhibitor, is the only standard clinical treatment against advanced hepatocellular carcinoma. However, development of resistance to sorafenib has raised concern in recent years due to the high-level heterogeneity of individual response to sorafenib treatment. The resistance mechanism underlying the impaired sen...
Interleukin 6 (IL6), tumor necrosis factor a (TNFα) and TNF receptor-1(TNFR1) have been shown to involve in oval cell proliferation and hepatocellular carcinoma (HCC) development. However, their role in these processes is still unclear. In the present study, by using hepatocytes-specific DDB1 deletion mouse models, we explored the role and mechanis...
Backgrounds:
Hepatocellular Carcinoma (HCC) is one of the most common malignancy of liver and HCC-related morbidity and mortality remains at high level. Researchers had investigated whether and how reduced E-cadherin expression impacted the prognosis of patients with HCC but the results reported by different teams remain inconclusive.
