Lysine acetylation is a conserved protein post-translational modification that links acetyl-coenzyme A metabolism and cellular signalling. Recent advances in the identification and quantification of lysine acetylation by mass spectrometry have increased our understanding of lysine acetylation, implicating it in many biological processes through the regulation of protein interactions, activity and localization. In addition, proteins are frequently modified by other types of acylations, such as formylation, butyrylation, propionylation, succinylation, malonylation, myristoylation, glutarylation and crotonylation. The intricate link between lysine acylation and cellular metabolism has been clarified by the occurrence of several such metabolite-sensitive acylations and their selective removal by sirtuin deacylases. These emerging findings point to new functions for different lysine acylations and deacylating enzymes and also highlight the mechanisms by which acetylation regulates various cellular processes.

This study investigated the edible quality differences in muscle segments of silver carp (Hypophthalmichthys molitrix) and established an evaluation model for processing suitability. The results showed that steamed dorsal meat had the highest levels of total free amino acids, umami amino acids, and total volatile compounds. Fried tail meat exhibited the highest content of sweet amino acids and equivalent umami concentration (EUC) values, which were superior in all fried meat parts compared to those that were steamed.

Background: The synchronized absorption of amino acids (AAs) and glucose in the gut is crucial for effective AA utilization and protein synthesis in the body. The study investigated how the starch digestion rate and AA levels impact intestinal AA digestion, transport and metabolism, breast muscle protein metabolism, and growth in grower broilers. A total of 720 21-day-old healthy male Arbor Acres Plus broilers were randomly assigned to 12 treatments, each with 6 replicates of 10 birds.

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.

Although a fraction of functional peptides concealed within long non-coding RNAs (lncRNAs) is identified, it remains unclear whether lncRNA-encoded peptides are involved in the malignancy of cervical cancer (CC). Here, a 92-amino acid peptide is discovered, which is named TUBORF, encoded by lncRNA TUBA3FP and highly expressed in CC tissues. TUBORF inhibits ferroptosis to promote the malignant proliferation of CC cells.

Purpose: This study seeks to investigate the fundamental molecular processes through which histone deacetylase 9 (HDAC9) governs the proliferation of glomerular mesangial cells in the context of immunoglobulin A nephropathy (IgAN) and to identify novel targets for clinical research on IgAN.
Methods: Data from high-throughput RNA sequencing for IgAN were procured from the Gene Expression Omnibus database to assess the expression profiles and clinical diagnostic significance of histone deacetylase family proteins (HDACs). Blood samples from 20 IgAN patients were employed in RT-qPCR analysis, and the spearman linear regression method was utilized to analyze the clinical correlation.
