AMPK‐Mediated Lipid Metabolic Reprogramming in Cancer: From Mechanisms to Targeted Therapies

open access: yesCell Biochemistry and Function, Volume 44, Issue 10, October 2026.
ABSTRACT AMP‐activated protein kinase (AMPK), a key regulator of cellular energy metabolism, is activated under conditions of energy stress to restore metabolic homeostasis by promoting catabolic pathways and inhibiting anabolic processes such as lipid synthesis. Multiple key molecules involved in lipid metabolism are regulated by AMPK, and its role in

Alleviation of intrasteric inhibition by the pathogenic activation domain mutation, D444N, in human cystathionine beta-synthase.

open access: yes, 2002
Item does not contain fulltextHuman cystathionine beta-synthase is a heme protein that catalyzes the condensation of serine and homocysteine to form cystathionine in a pyridoxal phosphate-dependent reaction. Mutations in this enzyme are the leading cause

Crosstalk Between Parkinson's Disease and Colorectal Cancer: Genetic Mechanisms, Gut Microbiota, and Therapeutic Insights

open access: yesHealth Care Science, Volume 5, Issue 5, Page 495-513, October 2026.
This review elucidates the crosstalk between Parkinson's disease and colorectal cancer, driven by shared genetics (PRKN, PINK1, DJ‐1) involving oxidative stress, cell cycle regulation, and inflammation. It identifies the gut microbiota—via functional amyloids and short‐chain fatty acids (SCFAs)—as a mechanistic bridge, offering insights for dual ...

Hyperhomocysteinemia and Vitamin B Deficiency as Potential Aggravating Factors in Huntington's Disease: A Prospective Monocentric Study

open access: yesMovement Disorders, Volume 41, Issue 10, Page 2712-2722, October 2026.
Abstract Background Although not confirmed, some studies have suggested that elevated homocysteine levels are common in patients with Huntington's disease (HD). Its clinical relevance remains unclear. Objectives We aimed to assess vitamin B and homocysteine levels in HD patients and explore the relationships among hyperhomocysteinemia, vitamin B ...

Inactivation of cystathionine β-synthase with peroxynitrite [PDF]

open access: yesArchives of Biochemistry and Biophysics, 2009
Cystathionine beta-synthase (CBS) is a homocysteine metabolizing enzyme that contains pyridoxal phosphate (PLP) and a six-coordinate heme cofactor of unknown function. CBS was inactivated by peroxynitrite, the product of nitric oxide and superoxide radicals. The IC(50) was approximately 150microM for 5microM ferric CBS.

Histone Post‐Translational Modifications Regulating Ferroptosis: The Molecular Mechanisms and Disease Associations

open access: yesCell Biochemistry and Function, Volume 44, Issue 9, September 2026.
ABSTRACT Ferroptosis is a form of programmed cell death characterized by iron‐dependent phospholipid peroxidation and is implicated in a wide range of human diseases. Emerging evidence highlights the critical role of epigenetic regulation in this process.

Effect of Cysteine on Expression of Cystathionine .BETA.-Synthase in the Rat Liver.

open access: yesJournal of Nutritional Science and Vitaminology, 1995
Hepatic cystathionine beta-synthase activity is decreased by the addition of cysteine to the diet. This effect of cysteine was slightly greater in diets containing 0.25% methionine than in those containing 1% methionine, and was reduced during aging.
