Splicing factor SRSF1 deficiency in the liver triggers NASH-like pathology and cell death Open
Regulation of RNA processing contributes profoundly to tissue development and physiology. Here, we report that serine-arginine-rich splicing factor 1 (SRSF1) is essential for hepatocyte function and survival. Although SRSF1 is mainly known…

Couplings of order six in the gauge field strength and the second fundamental form on a D$_p$-brane at order $α'^2$ Open
Using the assumption that the independent gauge invariant couplings on the world-volume of the non-perturbative objects in the string theory are independent of the background, we find the four and the six gauge field strength and/or the se…

Immunoglobulin G4 associated autoimmune cholangitis and pancreatitis following the administration of nivolumab: A case report Open
We hypothesize this case of IgG4 related cholangitis and pancreatitis was likely triggered by nivolumab.

Hepatocyte PPARγ contributes to the progression of non-alcoholic steatohepatitis in male and female obese mice Open
Background & Aims Non-alcoholic steatohepatitis (NASH) is associated with obesity and increased expression of hepatic peroxisome proliferator-activated receptor γ (PPARγ) in humans. Although we previously showed that the expression of PPAR…
