HNF1 and SREBP2 are important regulators of NPC1L1 in human liver

SREBP2 mediates the modulation of intestinal NPC1L1 expression by curcumin.

Curcumin, the major phenolic compound in the spice turmeric, exhibits numerous biological effects, including lowering plasma cholesterol and preventing diet-induced hypercholesterolemia. The mechanisms underlying the hypocholesterolemic effect of curcumin are not fully understood. In this regard, intestinal Niemann-Pick C1-like 1 (NPC1L1) cholesterol transporter, the molecular target of intesti...

Nitric oxide and endothelin-1 are important regulators of human ophthalmic artery.

The vascular endothelial cells have the ability to modulate local vascular tone by releasing relaxing factors such as nitric oxide or the vasoconstrictor peptide endothelin-1. Although this regulatory system is found in all vertebrates, there is a great heterogeneity in the release of these endothelium-derived substances, from one organ to an other, between large and small vessels, and between ...

NMDA receptors are important regulators of pancreatic cancer and are potential targets for treatment

Pancreatic cancer, particularly adenocarcinoma of the pancreas, is a common disease with a poor prognosis. In this study, the importance of N-methyl-D-aspartate (NMDA) receptors for the growth and survival of pancreatic cancer was investigated. Immunohistochemistry performed with antibodies against GluN1 and GluN2B revealed that all invasive adenocarcinoma and neuroendocrine pancreatic tumors l...

Are Abnormal Yolk Sac Characteristics Important Factors in Abortion Rates?

Calcium and potassium are important regulators of barrier homeostasis in murine epidermis.

Topical solvent treatment removes lipids from the stratum corneum leading to a marked increase in transepidermal water loss (TEWL). This disturbance stimulates a variety of metabolic changes in the epidermis leading to rapid repair of the barrier defect. Using an immersion system we explored the nature of the signal leading to barrier repair in intact mice. Initial experiments using hypotonic t...
