Hepatocytes paradoxically affect intrahepatic IFN-γ production in autoimmune hepatitis due to Gal-9 expression and TLR2/4 ligand release.

Hepatocytes are the targets in autoimmune hepatitis (AIH) that results in T cell-dependent liver injury. However, hepatocytes may also affect the hepatic T cells in AIH, but the underlying mechanisms are not fully understood. Here we report that hepatocytes could secrete galectin-9 (Gal-9) to suppress the intrahepatic production of Th1 cytokine IFN-γ and restrict AIH development, but hepatocyte damage resulted in opposite effects due to release of TLR2/4 ligands that promoted the intrahepatic production of IL-1β, IL-6, and IL-12.

Astrocyte elevated gene 1 (AEG-1) promotes anoikis resistance and metastasis by inducing autophagy in hepatocellular carcinoma.

Astrocyte elevated gene 1 (AEG-1) is overexpressed in hepatocellular carcinoma (HCC) and is strongly associated with tumor metastasis. Anoikis resistance and autophagy may play an important role in the survival of circulating tumor cells. However, the relationship among AEG-1, anoikis resistance, autophagy, and metastasis in HCC is still not clear.

Primary Cilia Blockage Promotes the Malignant Behaviors of Hepatocellular Carcinoma via Induction of Autophagy.

Primary cilia are organelles protruding from cell surface into environment that function in regulating cell cycle and modulating cilia-related signal. Primary ciliogenesis and autophagy play important roles in tumorigenesis. However, the functions and interactions between primary cilia and autophagy in hepatocellular carcinoma (HCC) have not been reported yet.

A Potential Model for Detecting Crowding-induced Epithelial Cell and Cancer Cell Extrusion.

Overcrowding and cell deformation lead to the shedding of apoptotic and live cells to maintain homeostasis in the epithelium. Recent studies have attempted to explain the effect of extrusion on epithelial homeostasis and tumor metastasis, but lack the requisite quantitative models for testing extrusion. Here, we designed a petri dish inversion model to detect the extrusion ability of both normal epithelial cells and epithelial cancer cells.

The prediction value of scoring systems in Mallory-Weiss syndrome patients.

Mallory-Weiss syndrome (MWS) is a relatively less common cause of nonvariceal upper gastrointestinal bleeding. There is limited data on whether scoring systems could be used to predict the clinical outcomes in patients with bleeding due to MWS. The aim of our study is to evaluate whether the Glasgow-Blatchford score (GBS), AIMS65, and shocking index are effective in predicting the clinical outcomes of MWS.
