Pyrroloquinoline quinone increases the expression and activity of Sirt1 and -3 genes in HepG2 cells. [PDF]

open access: yes, 2015
Sirtuin (Sirt) 1 and Sirt 3 are nicotinamide adenine dinucleotide ((+))-dependent protein deacetylases that are important to a number of mitochondrial-related functions; thus, identification of sirtuin activators is important. Herein, we hypothesize that

Time after time – circadian clocks through the lens of oscillator theory

open access: yesFEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Transcriptional activation of the cholesterol 7α-hydroxylase gene (CYP7A) by nuclear hormone receptors

open access: yesJournal of Lipid Research, 1998
The gene encoding cholesterol 7α-hydroxylase (CYP7A), the rate-limiting enzyme in bile acid synthesis, is transcriptionally regulated by bile acids and hormones. Previously, we have identified two bile acid response elements (BARE) in the promoter of the

Cell proliferation and oncogene expression after bile duct ligation in the rat: Evidence of a specific growth effect on bile duct cells [PDF]

open access: yes, 1995
The proliferative response of the rat liver was measured after temporary or permanent total biliary obstruction (BDO) and in different regions after selective ligation of the lobar ducts draining the right 60% of the hepatic mass.

Cytoplasmic p21 promotes stemness of colon cancer cells via activation of the NFκB pathway

open access: yesMolecular Oncology, EarlyView.
Cytoplasmic p21 promotes colorectal cancer stem cell (CSC) features by destabilizing the NFκB–IκB complex, activating NFκB signaling, and upregulating BCL‐xL and COX2. In contrast to nuclear p21, cytoplasmic p21 enhances spheroid formation and stemness transcription factor CD133.

MODY: Strategies for a unique form of diabetes

open access: yesJournal of Education and Health Promotion
Maturity-onset diabetes of the young (MODY) is a monogenic, autosomal dominant form of diabetes that typically presents before the age of 25. It is caused by mutations in single genes involved in insulin production and glucose regulation, leading to ...

Redox regulation meets metabolism: targeting PRDX2 to prevent hepatocellular carcinoma

open access: yesMolecular Oncology, EarlyView.
PRDX2 acts as a central redox hub linking metabolic dysfunction‐associated steatohepatitis (MASH) to hepatocellular carcinoma (HCC). In normal hepatocytes, PRDX2 maintains redox balance and metabolic homeostasis under oxidative stress. In contrast, during malignant transformation, PRDX2 promotes oncogenic signaling, stemness, and tumor initiation ...

HNF4A ameliorates acute liver failure by inhibiting NCOA4-mediated ferritinophagy

open access: yesScientific Reports
Intracellular iron homeostasis imbalance is linked to cellular ferroptosis and inflammatory injury diseases. NCOA4-mediated ferritin autophagy is vital for regulating intracellular iron homeostasis, but its impact on acute liver failure (ALF ...
