Hepatic steatosis is highly prevalent but is not correlated with stiffness in autoimmune hepatitis.

The prevalence and impact of hepatic steatosis among patients with autoimmune hepatitis (AIH) is not well described.We conducted a cross-sectional study to determine the prevalence of hepatic steatosis in AIH patients and examined its relationship with hepatic fibrosis using vibration controlled transient elastography. Liver stiffness measurement (LSM), controlled attenuation parameter (CAP), gender, current age, and body mass index (BMI) were collected from 277 AIH patients.

Evolutionary and developmental analysis reveals KANK genes were co-opted for vertebrate vascular development.

Gene co-option, usually after gene duplication, in the evolution of development is found to contribute to vertebrate morphological innovations, including the endothelium-based vascular system. Recently, a zebrafish kank gene was found expressed in the vascular vessel primordium, suggesting KANK genes are a component of the developmental tool kit for the vertebrate vascular system. However, how the KANK gene family is involved in vascular vessel development during evolution remains largely unknown.
