Circadian dysregulation disrupts bile acid homeostasis. [PDF]

PLoS ONE, 2009
BACKGROUND:Bile acids are potentially toxic compounds and their levels of hepatic production, uptake and export are tightly regulated by many inputs, including circadian rhythm.

A Link between cholesterol levels and phenobarbital induction of cytochromes P450 [PDF]

, 2002
Squalestatin1 (SQ1), a potent inhibitor of squalene synthase produced a dose-dependent induction of cytochromes P450 CYP2H1 and CYP3A37 mRNAs in chicken hepatoma cells. The effect of SQ1 was completely reversed by 25-hydroxycholesterol.

Targeting p21‐High Senescent Kupffer Cells Nanotherapeutically Potentiates Antitumor Immunity in Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombus

Advanced Science, EarlyView.
Schematic illustration of a biomimetic SKEV@AAV platform targeting p21‐high senescent Kupffer cells (sKCs) in hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT). p21‐high sKCs accumulate in the PVTT microenvironment and establish an immunosuppressive, SASP‐rich environment that facilitates tumor cell proliferation and immune evasion.

Nuclear Receptors as Targets for Drug Development: Regulation of Cholesterol and Bile Acid Metabolism by Nuclear Receptors

Journal of Pharmacological Sciences, 2005
Nuclear receptors are ligand-dependent transcription factors that recently have been shown to play important roles in the metabolism of cholesterol and bile acids.

Inhibition by sporidesmin of hepatocyte bile acid transport [PDF]

Biochemical Journal, 1983
Exposure of isolated rat hepatocytes (approx. 2 × 10(7)–5 × 10(7) cells/10ml of incubation mixture) to 0.5 mg of the mycotoxin sporidesmin for 30—60 min at 37 degrees C produced loss of plasma-membrane microvilli with some disruption of organelle distribution in the sub-surface region.

Psychological Stress Associated Bile Acid Reprogramming Promotes Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Depression is increasingly recognized as a risk factor for chronic diseases, yet its biological impact on cancer remains unclear. Using data from more than 490 000 participants across three international cohorts, we show that depression significantly increases the risk of liver cancer.

Bile acid-induced negative feedback regulation of the human ileal bile acid transporter [PDF]

Hepatology, 2004
Ileal expression of the apical sodium-dependent bile acid transporter (ASBT) in the rat is unaffected by bile salts, yet in the mouse it is under negative-feedback regulation. The bile acid responsiveness of human ASBT is unknown.

Targeting GALNT7 Disrupts the TAZ O‐GalNAcylation Feedback Loop to Suppress Gallbladder Cancer Progression

Advanced Science, EarlyView.
Aberrant GALNT7‐mediated O‐GalNAcylation stabilizes TAZ to drive gallbladder cancer progression through a feed‐forward transcriptional loop. Structure‐based screening identifies Olaparib as a potent GALNT7 antagonist that disrupts this oncogenic axis, providing an immediate therapeutic strategy for this aggressive malignancy.
