The replicative lifespan-extending deletion of SGF73 results in altered ribosomal gene expression in yeast. [PDF]

open access: yes, 2017
Sgf73, a core component of SAGA, is the yeast orthologue of ataxin-7, which undergoes CAG-polyglutamine repeat expansion leading to the human neurodegenerative disease spinocerebellar ataxia type 7 (SCA7).

Recycling Cohesin Rings by Deacetylation [PDF]

open access: yesMolecular Cell, 2010
In this issue of Molecular Cell, Beckouët et al. (2010) and Borges et al. (2010) identify the enzyme responsible for cohesin deacetylation in anaphase and show that de novo acetylation is required for cohesion establishment in the next cell cycle.

Chitosan: Sources, Processing and Modification Techniques

open access: yesGels, 2022
Chitosan, a copolymer of glucosamine and N-acetyl glucosamine, is derived from chitin. Chitin is found in cell walls of crustaceans, fungi, insects and in some algae, microorganisms, and some invertebrate animals. Chitosan is emerging as a very important

Toward a molecular understanding of yeast silent chromatin : roles for H4K16 acetylation and the Sir3 C-terminus [PDF]

open access: yes, 2012
Discrete regions of the eukaryotic genome assume a heritable chromatin structure that is refractory to gene expression. In budding yeast, silent chromatin is characterized by the loading of the Silent Information Regulatory (Sir) proteins (Sir2, Sir3 and

Acetate Revisited: A Key Biomolecule at the Nexus of Metabolism, Epigenetics and Oncogenesis—Part 1: Acetyl-CoA, Acetogenesis and Acyl-CoA Short-Chain Synthetases

open access: yesFrontiers in Physiology, 2020
Acetate is a major end product of bacterial fermentation of fiber in the gut. Acetate, whether derived from the diet or from fermentation in the colon, has been implicated in a range of health benefits.

JNK‐mediated Ser27 phosphorylation and stabilization of SIRT1 promote growth and progression of colon cancer through deacetylation‐dependent activation of Snail

open access: yesMolecular Oncology, 2022
Sirtuin 1 (SIRT1), an NAD+‐dependent histone/protein deacetylase, has multifaceted functions in various biological events such as inflammation, aging, and energy metabolism. The role of SIRT1 in carcinogenesis, however, is still under debate.

Piezoelectric Performance of Microbial Chitosan Thin Film Derived from Aspergillus oryzae

open access: yesInternational Journal of Renewable Energy Development, 2022
In this study, chitosan thin film derived from Aspergillus oryzae cell walls was fabricated and characterised. First, the chitosan from the fungal biomass was extracted (0.18 g/g) with 52.25% of degree of deacetylation obtained through Fourier transform ...

Low-Level Saturated Fatty Acid Palmitate Benefits Liver Cells by Boosting Mitochondrial Metabolism via CDK1-SIRT3-CPT2 Cascade. [PDF]

open access: yes, 2020
Saturated fatty acids (SFAs) (the "bad" fat), especially palmitate (PA), in the human diet are blamed for potential health risks such as obesity and cancer because of SFA-induced lipotoxicity. However, epidemiological results demonstrate a latent benefit

Green fabrication of chitosan from marine crustaceans and mushroom waste: Toward sustainable resource utilization

open access: yesGreen Processing and Synthesis, 2023
The exoskeletons of crabs, shrimp, and fish are major waste. These wastes contain chitin, an abundant natural polymer found next to cellulose. Thus, disposal of this waste becomes a huge problem for the environment; besides this, reutilization boosts the

Internuclear gene silencing in Phytophthora infestans is established through chromatin remodelling [PDF]

open access: yes, 2008
In the plant pathogen Phytophthora infestans, nuclear integration of inf1 transgenic DNA sequences results in internuclear gene silencing of inf1. Although silencing is regulated at the transcriptional level, it also affects transcription from other ...
