The Role of Nicotinamide in Cancer Chemoprevention and Therapy

open access: yesBiomolecules, 2020
Nicotinamide (NAM) is a water-soluble form of Vitamin B3 (niacin) and a precursor of nicotinamide-adenine dinucleotide (NAD+) which regulates cellular energy metabolism.

Activation of AMP-activated protein kinase by metformin induces protein acetylation in prostate and ovarian cancer cells [PDF]

open access: yes, 2016
AMP-activated protein kinase (AMPK) is an energy sensor and master regulator of metabolism. AMPK functions as a fuel gauge monitoring systemic and cellular energy status.

Myo‐Inositol Mitigates Oxidative Stress in Bovine Mammary Epithelial Cells via Activation of the SIRT5/Nrf2 Signaling Axis

open access: yesAnimal Research and One Health, EarlyView.
Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.

A preliminary study on the mechanism of Buzhong Yiqi Decoction in improving hemorrhoid symptoms by inhibiting endothelial cell pyroptosis through SIRT1

open access: yes结直肠肛门外科
[Objectives] To preliminarily investigate the mechanism of Buzhong Yiqi decoction in inhibiting endothelial cell pyroptosis via SIRT1. [Methods] A hemorrhoid model was established in SD rats by topical application of glacial acetic acid. Thirty rats were

Effect of H2S on the circadian rhythm of mouse hepatocytes

open access: yesLipids in Health and Disease, 2012
Background Dysregulation of circadian rhythms can contribute to diseases of lipid metabolism. NAD-dependent deacetylase sirtuin-1(SIRT1) is an important hub which links lipid metabolism with circadian clock by its deacetylation activity depends on ...

SUMOylation regulates LKB1 localization and its oncogenic activity in liver cancer [PDF]

open access: yes, 2019
BACKGROUND: Even though liver kinase B1 (LKB1) is usually described as a tumor suppressor in a wide variety of tissues, it has been shown that LKB1 aberrant expression is associated with bad prognosis in Hepatocellular Carcinoma (HCC).

Dietary Glutamine Supplementation Alleviated Rumen Epithelium Oxidative Damage and Apoptosis Induced by Feed Restriction via Maintaining Mitochondrial Homeostasis in Female Yaks

open access: yesAnimal Research and One Health, EarlyView.
Dietary glutamine (Gln) supplementation increased the ATP levels and promoted cell proliferation in the rumen epithelium of feed‐restricted yaks. Besides, Gln inhibited ROS accumulation and reduced oxidative damage and apoptosis in the rumen epithelium of feed‐restricted yaks.

SIRT1, resveratrol and aging

open access: yesFrontiers in Genetics
Aging is linked to a time-associated decline in both cellular function and repair capacity leading to malfunction on an organismal level, increased frailty, higher incidence of diseases, and death. As the population grows older, there is a need to reveal mechanisms associated with aging that could spearhead treatments to postpone the onset of age ...

Nicotinamide Reverses the Warburg Effect in CHO Cell Culture

open access: yesBiotechnology and Bioengineering, EarlyView.
Abstract The Warburg effect, the preferential conversion of glucose‐derived pyruvate to lactate despite available oxygen, is a key feature of Chinese hamster ovary (CHO) cell culture. Lactate accumulation in recombinant protein‐producing cell culture is an inefficient usage of glucose, as well as being deleterious to cells.

Emerging roles of telomeric chromatin alterations in cancer [PDF]

open access: yes, 2019
Telomeres, the nucleoprotein structures that cap the ends of eukaryotic chromosomes, play important and multiple roles in tumorigenesis. Functional telomeres need the establishment of a protective chromatin structure based on the interplay between the ...
