Research progress of SIRTs activator resveratrol and its derivatives in autoimmune diseases.

Autoimmune diseases (AID) have emerged as prominent contributors to disability and mortality worldwide, characterized by intricate pathogenic mechanisms involving genetic, environmental, and autoimmune factors. In response to this challenge, a growing body of research in recent years has delved into genetic modifications, yielding valuable insights into AID prevention and treatment. Sirtuins (SIRTs) constitute a class of NAD-dependent histone deacetylases that orchestrate deacetylation processes, wielding significant regulatory influence over cellular metabolism, oxidative stress, immune response, apoptosis, and aging through epigenetic modifications.

Research progress on Sirtuins (SIRTs) family modulators.

Sirtuins (SIRTs) represent a class of nicotinamide adenine dinucleotide (NAD+)-dependent protein deacetylases that exert a crucial role in cellular signal transduction and various biological processes. The mammalian sirtuins family encompasses SIRT1 to SIRT7, exhibiting therapeutic potential in counteracting cellular aging, modulating metabolism, responding to oxidative stress, inhibiting tumors, and improving cellular microenvironment. These enzymes are intricately linked to the occurrence and treatment of diverse pathological conditions, including cancer, autoimmune diseases, and cardiovascular disorders.

SIRT6 Reduces Rheumatoid Arthritis Injury by Inhibiting MyD88-ERK Signaling Pathway.

Background: Rheumatoid arthritis (RA) is an autoimmune disease characterized by destruction of synovial joints, abnormal immune responses and chronic inflammatory manifestations, which seriously affects patients' well-being. We explored this study to ascertain the effect and mechanism of silent information regulator 6 (SIRT6) on RA.

Methods: Genes of RA patients and normal volunteers were analyzed using Gene Expression Omnibus (GEO), Kyoto-Encyclopedia of Genes and Genomes (KEGG) and Disconet databases.

Sirtuin family in autoimmune diseases.

In recent years, epigenetic modifications have been widely researched. As humans age, environmental and genetic factors may drive inflammation and immune responses by influencing the epigenome, which can lead to abnormal autoimmune responses in the body. Currently, an increasing number of studies have emphasized the important role of epigenetic modification in the progression of autoimmune diseases.

PLD1 knockdown reduces metastasis and inflammation of fibroblast-like synoviocytes in rheumatoid arthritis by modulating NF-κB and Wnt/β-catenin pathways.

Considered as an autoimmune disease, rheumatoid arthritis (RA) is an chronic inflammatory disorder that causes inflammation of the joints. This study is performed with the aim to clarify the expression of phospholipase D1 (PLD1) in RA and its specific regulation role of RA as well as the underlying mechanisms. In this study, ynovial tissue samples were collected from RA patients, and RA-fibroblast-like synoviocytes (FLSs) were subsequently isolated.

Superb microvascular imaging (SMI) for evaluating hand joint lesions in patients with rheumatoid arthritis in clinical remission.

The utility of superb microvascular imaging (SMI) for evaluating hand joint lesions in patients with rheumatoid arthritis (RA) in clinical remission is unreported. This study aimed to compare SMI and power Doppler imaging (PDI) for the evaluation of hand joint lesions in these patients. Twenty-six patients with RA in clinical remission were enrolled.
