Objective: This study investigated the association between a missense SNP in the codon of ADD1 phosphorylation site and the susceptibility of non-cardia gastric cancer in a Chinese population.
Methods: PhosphoSitePlus and dbSNP database were combined to discover missense SNPs in the codon of phosphorylation site. Then, we genotyped the missense SNP in 1, 998 cases with non-cardia gastric cancer and 2, 008 cancer-free controls of Chinese descent. Analysis was conducted by using Logistic model adjusted by gender and age.
Results: The rs4963 in the codon of ADD1 phosphorylation site was found. The frequencies of the 3 rs4963 genotypes, CC, CG, GG, among controls were 25.2%, 50.4%, and 24.4%, respectively, among patients were 20.1%, 50.6%, and 29.3%, respectively. Compared with CC genotype, the rs4963 CG genotype and GG genotype significantly increased the risk of non-cardia gastric cancer with the odds ratios being 1.24 (95%CI: 1.06 ∼ 1.46, P = 0.008) and 1.49 (95%CI: 1.25 ∼ 1.78, P < 0.001), respectively.
Conclusions: Fnnctional polymorphism in the phosphorylation site of ADD1 (rs4963) may influence the susceptibility of non-cardia gastric cancer.

Serine 31 is a phospho-site unique to the histone H3.3 variant; mitotic phospho-Ser31 is restricted to pericentromeric heterochromatin, and disruption of phospho-Ser31 results in chromosome segregation defects and loss of p53-dependant G cell-cycle arrest. Ser31 is proximal to the H3.

Background: Acetyl phosphate (AcP) is a microbial intermediate involved in the central bacterial metabolism. In bacteria, it also functions as a donor of acetyl and phosphoryl groups in the nonenzymatic protein acetylation and signal transduction. In host, AcP was detected as an intermediate of the pyruvate dehydrogenase complex, and its appearance in the blood was considered as an indication of mitochondrial breakdown.

Neutrophils are essential for host defense against infections, but they also play a key role in acute and chronic inflammation. The protein tyrosine phosphatase non-receptor type 22 (PTPN22) gene encodes the lymphoid-specific tyrosine phosphatase (Lyp) and a genetic single-nucleotide polymorphism of PTPN22 rs2476601 (R620W) has been associated with several human autoimmune diseases, including rheumatoid arthritis (RA). Here, we investigated the role of Lyp in TNFα-induced priming of neutrophil ROS production and in the development of arthritis using new selective Lyp inhibitors.

Purpose: This study aimed to investigate that AKT1-Mediated NOTCH1 phosphorylation promotes gastric cancer (GC) progression via targeted regulation of IRS-1 transcription.
Methods: The study utilized databases such as PhosphositePlus, TRANSFAC, CHEA, GPS 5.0, and TCGA, along with experimental techniques including Western Blot, co-IP, in vitro kinase assay, construction of lentiviral overexpression and silencing vectors, immunoprecipitation, modified proteomics, immunofluorescence, ChIP-PCR, EdU assay, Transwell assay, and scratch assay to investigate the effects of AKT1-induced Notch1 phosphorylation on cell proliferation, invasion and migration in vitro, as well as growth and epithelial-mesenchymal transition (EMT) in vivo.

The active site density, intrinsic activity, and supporting substrate of cobalt phosphide catalysts are vital to their performance in alkaline water electrolysis. In this work, a CoP/CoP loaded on cellulose nanofiber-derived carbon aerogels (CP/CCAs) bifunctional electrocatalyst with a three-dimensional network and heterostructure is illustrated through sequential facile hydrothermal, freeze-drying, and phosphorylation processes. The three-dimensional network of carbon aerogels derived from cellulose nanofibers reveals a specific surface area of 183.
