Transcriptional regulation of the human cholesterol 7 alpha-hydroxylase gene (CYP7A) in HepG2 cells
Journal of Lipid Research, 1996 A stable HepG2 cell line harboring a human cholesterol 7 alpha-hydroxylase (CYP7A) minigene/luciferase reporter gene construct was selected for studying transcriptional regulation of CYP7A gene promoter.

From HBV to MASLD Cirrhosis: Mechanistic Insights and Therapeutic Strategies
Portal Hypertension &Cirrhosis, EarlyView.This review examines the epidemiological shift from hepatitis B virus (HBV) to metabolic dysfunction‐associated steatotic liver disease (MASLD) as the leading cause of cirrhosis globally. It highlights the distinct pathogenic mechanisms between HBV and MASLD cirrhosis and discusses evolving diagnostic tools and therapeutic strategies tailored to the ...

Oxysterols and Their Cellular Effectors [PDF]
, 2012 Oxysterols are oxidized 27-carbon cholesterol derivatives or by-products of cholesterol biosynthesis, with a spectrum of biologic activities. Several oxysterols have cytotoxic and pro-apoptotic activities, the ability to interfere with the lateral domain

VIEW, EarlyView.Unilateral mastication, a common oral habit, induces cognitive decline in rats by disrupting hippocampal cholesterol metabolism. It triggers astrocyte hyperplasia, enhances cholesterol synthesis, impairs transport/degradation, and reduces 24‐hydroxycholesterol (24‐OHC), ultimately damaging synaptic function.

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.ABSTRACT Background Cell senescence (CS) and lipid metabolism (LM) disorders have been reported in chronic rhinosinusitis with nasal polyps (CRSwNP). However, the mechanism is still unclear. Methods Data were obtained from public databases; differential expression analysis and machine learning were performed to identify biomarkers and to understand the

Neurodegeneration: Potential Causes, Prevention, and Future Treatment Options [PDF]
, 2011 Here I advance a hypothesis that neurodegeneration is a natural process associated with aging due to the loss of genetic redundancy following a mathematical model R(t) = R0(1-αe(βC+γI+δEt)t), where the calorie intake (C) and ...

Novel approaches for drug development against chronic primary pain: A systematic review
British Journal of Pharmacology, EarlyView.Abstract Chronic primary pain (CPP) persisting for more than 3 months, associated with significant emotional distress without any known underlying cause, is an unmet medical need. Traditional or adjuvant analgesics do not provide satisfactory pain relief for a great proportion of these patients.
