A SNP of NPC1L1 Affects Cholesterol Absorption in Japanese
Ezetimibe is known to target Niemann-Pick Type C1 Like1 (NPC1L1), a key protein in intestinal cholesterol absorption, and thus to decrease serum LDL-cholesterol (LDL-C) levels. The response of serum LDL-C levels to ezetimibe was reported to differe among NPC1L1 haplotypes.We analyzed NPC1L1 genotypes in Japanese and investigated differences in markers ...

SummaryNiemann-Pick C1-like 1 (NPC1L1) is a polytopic transmembrane protein that plays a critical role in cholesterol absorption. Ezetimibe, a hypocholesterolemic drug, has been reported to bind NPC1L1 and block cholesterol absorption.

Human NPC1L1 Expression is Positively Regulated by PPARα
Pharmaceutical Research, 2010Niemann-Pick C1-like 1 (NPC1L1), a pharmacological target of ezetimibe, is responsible for cholesterol absorption in enterocytes and hepatocytes. In the present study, the involvement of peroxisome proliferator-activated receptor α (PPARα) and its cofactor, PPARγ coactivator 1α (PGC1α) in the transcriptional regulation of human NPC1L1 was analyzed ...

Sequencing of a npc1L1 mutation in larval zebrafish
Proceedings of the West Virginia Academy of Science, 2020NPC1L1 transport protein is located in the lumen of the intestines and is critical for cholesterol absorption. The reason why we study NPC1L1 is because cholesterol absorption in the intestines affect obesity and diabetes which is still under investigation.

Sequencing of an npc1L1 mutation in larval zebrafish.
Proceedings of the West Virginia Academy of Science, 2019How the intestinal absorption of lipids impact dyslipidemias such as obesity and diabetes is currently under debate. NPC1L1 is a critical transport protein in enterocyte cholesterol absorption. To understand the mechanism of intestinal NPC1L1 uptake within the enterocyte, we are creating a npc1l1 -/- (knockout) line in zebrafish.

Emodin lows NPC1L1-mediated cholesterol absorption as an uncompetitive inhibitor
Bioorganic & Medicinal Chemistry Letters, 2022Emodin (EM) is one of the active components of the traditional Chinese medicine rhubarb, and there is evidence of its hypolipidemic activity, though the exact mechanism is unknown. NPC1L1 is a key protein in human cholesterol uptake that is primarily expressed in hepatocytes and gastrointestinal epithelial cells.

HNF4α is a Crucial Modulator of the Cholesterol-Dependent Regulation of NPC1L1
Pharmaceutical Research, 2007Niemann-Pick C1-like 1 (NPC1L1) has been identified as a target of ezetimibe and found to be responsible for intestinal cholesterol absorption. Although, it was recently demonstrated that sterol responsive element binding protein 2 (SREBP2) is responsible for the cholesterol-dependent down-regulation of NPC1L1, the molecular mechanism of NPC1L1 ...
