AKAP12/Gravin is over-expressed in patients with ulcerative colitis

AbstractThe gene of A-kinase anchor protein 12 (AKAP12) regulates cell cycle progression, cell motility, and morphology through its multiple scaffolding domains. However, the role of AKAP12 expression in ulcerative colitis (UC) patients has not been yet described. The aim of the study was to describe the gene and protein of AKAP12 expression in patients with UC and its association regarding the disease severity. We included a total of 40 patients with confirmed diagnosis of UC and 25 controls without endoscopic evidence of colitis or neoplasia. The relative quantification of the gene expression was performed by real-time PCR for AKAP12. Kruskal –Wallis was used to test differences among groups, and Spearman correlation to assess the relationship between AKAP12 gene and clinical outcomes. The extent of disease was evaluated using total colonoscopy, and biopsies were taken from rectum segments. The AKAP12 gene expression was increased in c olonic mucosa from patients with active UC when compared with UC remission and control group. The overexpression of AKAP12 in patients with UC was associated with the presence of extensive colitis (p = 0.04, RM = 12, IC = 1.29–186.37). AKAP12/CD16 double positive cells were higher in submucosa (p = 0.04), muscular (p <  0.001), and cells from serosa (p <  0.001) in patients affected by UC in comparison to controls. The overexpression of AKAP12 was associated with the extent of disease. This is the first repor...
