Background: Preoperative hepatitis B virus (HBV) DNA level has been shown to correlate with the prognosis of patients with HBV-associated hepatocellular carcinoma (HCC) following liver resection, but its dynamic changes have not been reported. The aim of this longitudinal multicenter retrospective observational study was to describe the trajectory of HBV DNA after R0 liver resection in patients receiving antiviral therapy and to investigate its impact on clinical outcomes.
Methods: This study included patients with HBV-related HCC from nine hospitals in China who received antiviral therapy and R0 hepatectomy between 2015 and 2016.
Metastasis is the main cause of colorectal cancer (CRC)-related death, and the 5-year relative survival rate for CRC patients with distant metastasis is only 14%. X-linked inhibitor of apoptosis (XIAP)-associated factor 1 (XAF1) is a zinc-rich protein belonging to the interferon (IFN)-induced gene family. Here, we report a metastasis-promoting role of XAF1 in CRC by acting as a novel adaptor of valosin-containing protein (VCP).

Methods: This retrospective study analyzed HCC patients who received sintilimab between January 2019 and December 2020 at four centers in China.
Advanced biliary tract cancer (BTC) has a poor prognosis, even after combined chemotherapy of gemcitabine and oxaliplatin (GEMOX). To investigate the efficacy and safety of GEMOX chemotherapy combining atezolizumab and bevacizumab in advanced BTC, the authors designed an open-label, single-arm, phase II clinical trial and will enroll patients with stage IV BTC. The participants will receive GEMOX chemotherapy combined with atezolizumab plus bevacizumab.

Objectives: We investigated the efficacy and safety of atezolizumab, bevacizumab, and gemcitabine plus oxaliplatin (GEMOX) in advanced BTC and explore the potential biomarkers related to the response.
Design: Multicenter, single-arm, retrospective study.
Background And Aims: The efficacy and safety of systemic atezolizumab and bevacizumab (atezo/bev) in treatment of patients with unresectable hepatocellular carcinoma (HCC) have been demonstrated. However, the efficacy of this treatment in patients with HCC and extrahepatic portal vein tumor thrombus (ePVTT) is not satisfactory. This study aimed to study the efficacy and safety of combining intensity-modulated radiotherapy (IMRT) with systemic atezo/bev in treatment of these patients.

The efficacy of available therapeutic regimens for unresectable HCC is not satisfactory in HCC with portal vein tumour thrombosis (PVTT). Therefore, this open-label, single-arm phase II clinical trial aims to investigate the efficacy and safety of radiotherapy combined with atezolizumab plus bevacizumab in treating HCC patients with PVTT.

Non-alcoholic fatty liver disease (NAFLD) has become a growing public health problem. However, the complicated pathogenesis of NAFLD contributes to the deficiency of effective clinical treatment. Here, we demonstrated that liver-specific loss of Arid2 induced hepatic steatosis and this progression could be exacerbated by HFD.

Herein, we designed an open-label, single-arm phase II clinical trial to investigate the efficacy and safety of TACE combined with atezolizumab plus bevacizumab for patients with Barcelona Clinic Liver Cancer (BCLC) stage-B HCC. Patients will initially receive TACE.

Considering the emergence of resistance to therapies, it is urgent to develop more effective therapies to improve the prognosis. Here we reported that pancreatic progenitor cell differentiation and proliferation factor (PPDPF) deficiency inhibited LUAD development both in vitro and in vivo.

Background & Aims: Hepatocellular carcinoma (HCC) is a highly heterogeneous solid tumor with high morbidity and mortality. AT-rich interaction domain 1A (ARID1A) accounts for up to 10% of mutations in liver cancer, however, its role in HCC remains controversial, and no targeted therapy has been established.
Methods: The expression of ARID1A in clinical samples was examined by Western blot and immunohistochemical staining.
Ochratoxin A(OTA) is considered to be one of the most important contaminants of food and feed worldwide. The liver is one of key target organs for OTA to exert its toxic effects. Due to current lifestyle and diet, nonalcoholic fatty liver disease (NAFLD) has been the most common liver disease.

In this work, we investigated the therapeutic efficacy of Terbinafine for HCC and the underlying mechanism. The influence of Terbinafine on cell growth, 3D spheroid formation, clonogenic survival, and protein synthesis was investigated in human HCC cell lines.

Thus, it is urgent to find effective therapeutic targets for clinical intervention. In this study, we find that liver-specific knockout of PPDPF (PPDPF-LKO) leads to spontaneous fatty liver formation in a mouse model at 32 weeks of age on chow diets, which is enhanced by HFD.

However, the role of NET1 in hepatocellular carcinoma (HCC) remains largely uncovered. In this study, we found that NET1 expression was upregulated in HCC, and that upregulated NET1 expression was closely associated with poor prognosis and some clinical characteristics in HCC patients.

In this study, we report that expression of choroideremia-like (CHML) is increased in HCC, associated with poor survival, early recurrence and more satellite nodules in HCC patients. CHML promotes migration, invasion and metastasis of HCC cells, in a Rab14-dependent manner.

In this study, we need to explore its role in hepatocellular carcinoma that remains largely elusive.
Materials And Methods: The expression of WISP3/CCN6 was analysed by qRT-PCR and Western blotting.
Two isoforms of human Polycomb-like protein 3 (hPCL3) have been reported as components of the nuclear Polycomb repressive complex 2 (PRC2), with the short isoform (hPCL3s) showing a dominant cytoplasmic localization. The function of cytoplasmic hPCL3s has, however, not been addressed. In this study, we report that hPCL3s is upregulated in clinical hepatocellular carcinoma (HCC) samples and its expression correlated with HCC clinical features.
