Identification of Menopausal and Reproductive Risk Factors for Microscopic Colitis – Results From the Nurses’ Health Study
Microscopic colitis is a chronic inflammatory disorder of the colon primarily affecting postmenopausal women. However, the relationship between hormonal determinants, including reproductive and menopausal factors, and risk of microscopic colitis has ye… Continue reading
FXR-Dependent Modulation of the Human Small Intestinal Microbiome by the Bile Acid Derivative Obeticholic Acid
Intestinal bacteria can modify the composition of bile acids and bile acids, which are regulated by the farnesoid X receptor (FXR), affect the survival and growth of gut bacteria. We studied the effects of obeticholic acid (OCA), a bile acid analog and… Continue reading
Effects of Long-term Norfloxacin Therapy in Patients with Advanced Cirrhosis
There is debate over the effects of long-term oral fluoroquinolone therapy in patients with advanced cirrhosis. We performed a randomized controlled trial to evaluate the effects of long-term treatment with the fluoroquinolone norfloxacin on survival o… Continue reading
Risk of Hepatocellular Cancer in Patients with Non-alcoholic Fatty Liver Disease
There are limited data on the risk of hepatocellular cancer (HCC) in patients with non-alcoholic fatty liver disease (NAFLD). We aimed to estimate the risk of incident HCC among patients with NAFLD. Continue reading
TM6SF2 Promotes Lipidation and Secretion of Hepatitis C Virus in Infected Hepatocytes
Hepatitis C virus (HCV) co-opts the very low-density lipoprotein (VLDL) pathway for morphogenesis, maturation, and secretion, and circulates as lipoviroparticles (LVPs). We investigated the functions and underlying mechanisms of the lipid-associated tr… Continue reading
Efficacy of Secretagogues in Patients With Irritable Bowel Syndrome With Constipation: Systematic Review and Network Meta-analysis
Several secretagogues have been approved treatment of irritable bowel syndrome with constipation (IBS-C). However, their relative efficacy is unclear because there have been no head-to-head randomized controlled trials. We conducted a network meta-anal… Continue reading
An Inhibitor of GSK3B and HDACs Kills Pancreatic Cancer Cells and Slows Pancreatic Tumor Growth and Metastasis in Mice
Growth, progression, and drug resistance of pancreatic ductal adenocarcinomas (PDACs) have been associated with increased levels and activity of glycogen synthase kinase 3 beta (GSK3B) and histone deacetylases (HCACs). We designed and synthesized molec… Continue reading
Loss of MYO5B Leads to Reductions in Na+ Absorption with Maintenance of CFTR-dependent Cl- Secretion in Enterocytes
Inactivating mutations in myosin VB (MYO5B) cause microvillus inclusion disease (MVID), but the physiological cause of the diarrhea associated with this disease is unclear. We investigated whether loss of MYO5B results in aberrant expression of apical … Continue reading
Evidence of Chronic Allograft Injury in Liver Biopsies From Long-term Pediatric Recipients of Liver Transplants
A substantial proportion of pediatric liver transplant recipients develop subclinical chronic allograft injury. We studied whether there are distinct patterns of injury based on histopathology features and identified associated immunological profiles. Continue reading
GNASR201C Induces Pancreatic Cystic Neoplasms in Mice That Express Activated KRAS by Inhibiting YAP1 Signaling
Mutations at hot spots in GNAS, which encodes stimulatory G-protein, alpha subunits, are detected in ∼60% of intraductal papillary mucinous neoplasms (IPMNs) of the pancreas. We generated mice with KRAS-induced IPMNs that also express a constitutivel… Continue reading
