Comprehensive analysis of the prognostic, immunological, and diagnostic roles of SIRT1 in pan-cancer and its validation in KIRC.

Background: Disturbances in DNA damage repair may lead to cancer. SIRT1, an NAD+-dependent deacetylase, plays a crucial role in maintaining cellular homeostasis through the regulation of processes such as histone posttranslational modifications, DNA repair, and cellular metabolism. However, a comprehensive exploration of SIRT1's involvement in pan-cancer remains lacking.

Background: Despite promising preclinical studies, the application of DNA methyltransferase inhibitors in treating patients with solid cancers has thus far produced only modest outcomes. The presence of intratumoral heterogeneity in response to DNA methyltransferase inhibitors could significantly influence clinical efficacy, yet our understanding of the single-cell response to these drugs in solid tumors remains very limited.
Methods: In this study, we used cancer/testis antigen genes as a model for methylation-dependent gene expression to examine the activity of DNA methyltransferase inhibitors and their potential synergistic effect with histone deacetylase inhibitors at the single-cancer cell level.
N-carboxyethyl-lysin influences atherosclerotic plaque stability through ZKSCAN3 acetylation-regulated macrophage autophagy via the RAGE/LKB1/AMPK1/SIRT1 pathway.

Atherosclerosis, a chronic inflammatory condition characterized by plaque formation, often leads to instability, particularly under Type 2 diabetes mellitus (T2DM) conditions, which exacerbate cardiovascular risks. However, the molecular mechanisms underlying this process remain incompletely understood. In this study, we investigated the correlation between acute coronary syndrome (ACS) and serum levels of Nε-carboxyethyl-lysin (CEL), a prominent advanced glycation end product (AGE) elevated in T2DM, in a cohort of 225 patients with coronary artery disease.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) is the most prevalent chronic liver disease and can affect individuals without producing any symptoms. We aimed to explore the value of serum sirtuin-1 (Sirt-1) in the diagnosis of MASLD.
Methods: This case-control study analyzed data collected from 190 individuals aged 20 to 60 years.

The neuronal cytoskeleton has remained a less explored area of research in establishing neuroprotection. HDAC6 has been studied with respect to many neurodegenerative diseases, especially AD. It exhibits the ability to interact with various cytoskeletal proteins and to promote migration in cells.
