S100 calcium binding protein A8

CagA, SUR1, Calgranulin A, S100A8, MRP8
The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in the inhibition of casein kinase and as a cytokine. Altered expression of this protein is associated with the disease cystic fibrosis. [provided by RefSeq, Jul 2008] (from NCBI)

Papers on CagA
Bacterial protein toxins in human cancers.
Fabbri et al., Roma, Italy. In Pathog Dis, Feb 2016
Some toxins, like CDT and colibactin, directly attack the genome by damaging DNA whereas others, as for example CNF1, CagA and BFT, impinge on key eukaryotic processes, such as cellular signalling and cell death.
Molecular mechanisms of gastric cancer initiation and progression by Helicobacter pylori.
Merrell et al., Bethesda, United States. In Curr Opin Infect Dis, Feb 2016
In addition to utilizing the oncogenic CagA toxin to alter host cell signaling pathways, H. pylori also induces host DNA damage and alters DNA methylation to perturb downstream signaling.
Calprotectin (S100A8/A9) and S100A12 are associated with measures of disease activity in a longitudinal study of patients with rheumatoid arthritis treated with infliximab.
Halse et al., Bergen, Norway. In Scand J Rheumatol, Feb 2016
OBJECTIVES: The pro-inflammatory proteins calprotectin (a heterocomplex of S100A8/A9) and S100A12 have been associated with disease activity in rheumatoid arthritis (RA).
Osteoarthritis year in review 2015: biology.
Malfait, Chicago, United States. In Osteoarthritis Cartilage, Jan 2016
Highlights include a homeostatic role for CXC chemokines in cartilage, identification of the zinc-ZIP8-MTF1 axis as an essential regulator of cartilage catabolism, and the discovery that a small aggrecan fragment can have catabolic and pro-inflammatory effects through Toll-like receptor 2. Synovitis can promote joint damage, partly through alarmins such as S100A8.
The Nucleotide-Binding Sites of SUR1: A Mechanistic Model.
Puljung et al., Oxford, United Kingdom. In Biophys J, Jan 2016
ATP-sensitive potassium (KATP) channels comprise four pore-forming Kir6.2 subunits and four modulatory sulfonylurea receptor (SUR) subunits.
Helicobacter pylori strains harboring babA2 from Indian sub population are associated with increased virulence in ex vivo study.
Mukhopadhyay et al., Calcutta, India. In Gut Pathog, Dec 2015
BACKGROUND: The babA2 gene along with the cagA and vacA of Helicobacter pylori has been considered as a risk factor for the disease outcome in certain populations.
Molecular and Structural Analysis of the Helicobacter pylori cag Type IV Secretion System Core Complex.
Cover et al., Nashville, United States. In Mbio, Dec 2015
H. pylori is an important cause of stomach cancer, and the H. pylori T4SS contributes to cancer pathogenesis by mediating entry of CagA (an effector protein regarded as a "bacterial oncoprotein") into gastric epithelial cells.
Beyond Cholesterol - New Cardiovascular Biomarkers.
Mangge, In Nestle Nutr Inst Workshop Ser, Dec 2015
New biomarkers in these mechanisms include pentraxin 3, calprotectins S100A8/S100A9, myeloperoxidase, adiponectin, interleukins, and chemokines.
Role of Helicobacter pylori in gastric cancer: advances and controversies.
Qiao et al., Lanzhou, China. In Discov Med, Nov 2015
HP can be classified into different types based on the presence and expression level of CagA and VacA, and, when exposed to adverse environment, HP changes its phenotype from helical type to coccoid type, with each having different pathogenicity.
Modelling human development and disease in pluripotent stem-cell-derived gastric organoids.
Wells et al., Cincinnati, United States. In Nature, 2015
Using hGOs to model pathogenesis of human disease, we found that H. pylori infection resulted in rapid association of the virulence factor CagA with the c-Met receptor, activation of signalling and induction of epithelial proliferation.
Hypertension in Type 2 Diabetes Mellitus: Do We Need to Redefine the Role of Sulfonylureas?
Sehra et al., New Delhi, India. In Recent Pat Cardiovasc Drug Discov, 2014
RESULTS: Sulfonylureas due to their action on SUR1 in pituitary gland may release growth hormone and anti-diuretic hormone; action on SUR2B acting upon smooth muscle may interfere with vasodilatation, thereby causing hypertension.
