As an important risk factor for Hepatocellular Carcinoma (HCC), Hepatitis C Virus (HCV) infection can induce cirrhosis and HCC. But, the molecular mechanisms of HCV-induced transformation remain largely unknown. In this study, first, we identified the dysfunctional protein interaction networks in cirrhosis and HCC based on the gene expression profiles of 19(More)
BACKGROUND Inference of causal regulators responsible for gene expression changes under different conditions is of great importance but remains rather challenging. To date, most approaches use direct binding targets of transcription factors (TFs) to associate TFs with expression profiles. However, the low overlap between binding targets of a TF and the(More)
FGF21 is a novel secreted protein with robust anti-diabetic, anti-obesity, and anti-atherogenic activities in preclinical species. In the current study, we investigated the signal transduction pathways downstream of FGF21 following acute administration of the growth factor to mice. Focusing on adipose tissues, we identified FGF21-mediated downstream(More)
Obesity is associated with insulin resistance, a major risk factor for type 2 diabetes and cardiovascular disease. However, not all obese individuals are insulin resistant, which confounds our understanding of the mechanistic link between these conditions. We conducted transcriptome analyses on 835 obese subjects with mean BMI of 48.8, on which we have(More)
