PROBLEM: Question: Does peroxiredoxin 1 promote pancreatic cancer cell invasion by modulating p38 MAPK activity?

PROBLEM: Question: Does addition of Dexamethasone alter the Bile Acid Composition by Inducing CYP8B1 in Primary Cultures of Human Hepatocytes?
Answer: Primary human hepatocytes have an increased bile acid synthesis rate when cultured on matrigel as compared to collagen. Exposure to glucocorticoid hormones stimulates the expression of CYP8B1, leading to an increased formation of CA and alteration of the bile acid composition. The effect is most likely mediated through a GR-independent pathway, possibly through ROR α.

SOLUTION:
yes
