Tauroursodeoxycholic acid suppresses biliary epithelial cell apoptosis and endoplasmic reticulum stress by miR-107/NCK1 axis in a FXR-dependent manner.

Tauroursodeoxycholic acid (TUDCA can activate farnesoid X receptor (FXR) to involve in the formation of gallstones. Here, this study aimed to probe the potential mechanism of TUDCA-FXR network in the formation of bile duct stone. The levels of TUDCA, FXR and NCK1 were decreased, while the level of miR-107 was increased in the serum of bile duct stone patients.

WWP2 overexpression inhibits the antitumor effects of doxorubicin in hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is a common liver cancer that accounts for 90% of cases. Doxorubicin exhibits a broad spectrum of antitumor activity and is one of the most active agents in HCC. WW domain-containing protein 2 (WWP2) is highly expressed in HCC tissues and activates protein kinase B (AKT) signaling pathway to enhance tumor metastasis.

G protein-coupled receptor 30 activation protects hepatic ischemia-reperfusion injury of liver tissue through inhibiting NLRP3 in the rat model.

One of the most prominent characteristics of hepatic ischemia-reperfusion injury (HI/R) is an intense inflammatory reaction, which plays a key role in inflammatory injury induced by ischemia-reperfusion. Nucleotide-binding oligomerization domain-containing protein (NOD-), leucine-rich repeat (LRR), and pyrin domains-containing protein 3 (NLRP3) are involved in the inflammatory injury of ischemia-reperfusion as an important pattern recognition receptor for innate immunity. G protein-coupled receptor 30 (GPR30) is a newly identified as 7-transmembrane G protein-coupled receptor and can be activated by many stimulations including estrogen.

Effects of avitinib on the pharmacokinetics of osimertinib in vitro and in vivo in rats.

Background: Avitinib is one type of the third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) for the treatment of non-small cell lung cancer (NSCLC) with EGFR mutations. The purpose of this study was to investigate the effect of avitinib on the pharmacokinetics of osimertinib, one FDA approved third-generation TIKI, both in vitro and in vivo.

Methods: The in vitro metabolic stability and inhibitory effect of avitinib on osimertinib were assessed with rat liver microsomes (RLM) to determine its IC values.

Lamc1 promotes the Warburg effect in hepatocellular carcinoma cells by regulating PKM2 expression through AKT pathway.

Hepatocellular carcinoma (HCC), the most common aggressive malignancy of liver, is the third leading cause of cancer death across the world. Laminin gamma 1 (Lamc1), encodes laminin-γ1, an extracellular matrix protein involved in various progresses such as tumor cell proliferation and metabolism. In the present study, high expression of Lamc1 and PKM2 was observed in tumor tissues of HCC patients.

Ezrin expression in the primary hepatocellular carcinoma patients and associated with clinical, pathological characteristics.

Objective: The aim of this study was to assess Ezrin expression in the primary hepatic carcinoma patients and associated with clinical, pathological characteristics.

Materials And Methods: Fifty-one patients with primary hepatocellular carcinoma (PHC) with completed clinical data were retrospectively analyzed in this study. The Ezrin expression in PHC and normal control liver tissue was tested by immunohistochemical assay.

Inhibition of WWP2 suppresses proliferation, and induces G1 cell cycle arrest and apoptosis in liver cancer cells.

Primary liver cancer is one of the most common and aggressive human malignancies worldwide. As numerous studies have revealed that WW domain containing E3 Ub‑protein ligase 2 (WWP2) exerts cancer‑specific functions, the present study assessed the role of WWP2 in liver cancer. WWP2 was revealed to be significantly overexpressed in liver cancer tissues compared with paired normal tissues at the mRNA as well as at the protein level.

Silencing of WWP2 inhibits adhesion, invasion, and migration in liver cancer cells.

The role and clinical implication of the WWP2 E3 ubiquitin ligase in liver cancer are poorly understood. In the current study, we investigated the expression level of WWP2 and its functions in cell adhesion, invasion, and migration in liver cancer. We used real-time PCR to detect the expression of WWP2 in liver cancer and adjacent samples from the People's Hospital of Lishui and also analyzed The Cancer Genome Atlas (TCGA) RNA-seq data by bioinformatics.

Comparison of transumbilical single-port laparoscopic cholecystectomy and fourth-port laparoscopic cholecystectomy.

This work aims to compare the curative effect of transumbilical single-port laparoscopic cholecystectomy (TUSPLC) and four-port laparoscopic cholecystectomy (FPLC). 200 patients with cholecystolithiasis were enrolled in this study. They were randomly divided into TUSPLC group and FPLC group, 100 cases in each group, and the TUSPLC and FPLC was performed, respectively.

Laparoscopic surgery is more advantageous than laparotomic surgery for treatment of hypersplenism with gallstones.

Background: The aim of this study was to compare laparoscopic vs. laparotomic surgery for the treatment of hypersplenism with gallstones.

Methods: Forty patients were treated with splenectomy and cholecystectomy using either totally laparoscopic surgery (laparoscopic group) or laparotomy (laparotomy group).

The association of renin-angiotensin system genes with the progression of hepatocellular carcinoma.

Hepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Angiogenesis is reported to play a pivotal role in the occurrence, development and metastasis of HCC. The renin-angiotensin system (RAS) is involved in the regulation of angiogenesis.

Effect of DAPK1 gene on proliferation, migration, and invasion of carcinoma of pancreas BxPC-3 cell line.

DAPK1 can induce apoptosis in several cells; to determine the effect of DAPK1 would provide a new potential therapeutic strategy for treating pancreatic cancer. The aim of the present study was to investigate the effect of DAPK1 gene on proliferation, migration, and invasion of carcinoma of pancreas BxPC-3 cell line and explore the possible mechanisms. In our study, DAPK1 over-expressed cells were established by using the lentiviral transfection method, and DAPK1 obviously increased in BxPC-3 cells after transient transfection.
