• Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Can Your Diet Affect Your Risk for Gallstone-related Pancreatitis?

Consumption of red meat, saturated fat, and cholesterol increase risk for gallstone-related acute pancreatitis, researchers report in the February issue of Clinical Gastroenterology and Hepatology. Dietary fiber protects against acute pancreatitis—related and unrelated to gallstones—whereas coffee protects against acute pancreatitis not associated with gallstones, the study of thousands of patients

Can Disruption of the Intestinal Epithelial Barrier Contribute to Steatohepatitis?

Mice with defects in intestinal epithelial permeability develop more severe steatohepatitis when placed on a diet high in saturated fat, fructose, and cholesterol (HFCD) than control mice, and colon tissues from patients with non-alcoholic fatty liver disease (NAFLD) have similar defects in intestinal epithelial permeability, researchers report in the October

  • How Could Variants in TM6SF2 Affect Risk for NAFLD?

How Could Variants in TM6SF2 Affect Risk for NAFLD?

The human transmembrane 6 superfamily member 2 (TM6SF2) protein regulates cholesterol metabolism in mice, researchers report in the May issue of Gastroenterology. These findings provide insight into the how a variant of TM6SF2 (encoding the amino acid change E167K) reduces total cholesterol and low-density lipoprotein cholesterol (LDL-c) levels in humans, and

New Treatment Approved by FDA for Lysosomal Acid Lipase Deficiency

The Food and Drug Administration (FDA) approved a drug called sebelipase alfa (Kanuma) as the first-ever treatment for lysosomal acid lipase deficiency (LAL)—a rare inherited disorder. LAL deficiency causes a build-up of fats within the cells of various tissues that can lead to liver and cardiovascular diseases and other complications.

  • What Controls Liver Size?

What Controls Liver Size?

Most people know that liver can regenerate, but how does it know when to stop growing? Liver size is, in part, regulated by the size of the circulating bile acid pool, controlled by fibroblast growth factor 19 (FGF19), researchers show in the September issue of Gastroenterology. The mammalian liver can

  • How Does Vitamin D Lower Cholesterol?

How Does Vitamin D Lower Cholesterol?

Researchers have identified a mechanism by which vitamin D reduces levels of cholesterol. In a mouse study published in the April issue of Gastroenterology, Edwin Chow et al. show that activation of the vitamin D receptor increases cholesterol 7α-hydroxylase (CYP7A1)—an enzyme that metabolizes cholesterol—by downregulating its repressor, SHP. Studies have

How Do Lipids Affect Liver Disease?

Changes in lipid intake or metabolism can affect development of liver injury and fibrosis, according to two studies in mice published in the January issue of Gastroenterology. The liver is an important site of energy production and lipid metabolism. However, accumulation of excess fat in the liver promotes development of fibrosis, cirrhosis

Treatment for Gallstones?

Cholesterol gallstone disease might be treated with activators of the pregnane X receptor (PXR) such as St. John’s Wort, according to a study in the June issue of Gastroenterology. Cholesterol gallstone disease is caused by a biochemical imbalance of lipids and bile salts in the gallbladder bile. Jinhan He et
