S of mRNA versus the protein of PKCa. In addition, the IQ-1 site catalytically-competent PKCa molecules in cells are tightly regulated by phosphorylation, cofactor binding, and intracellular localization. PKCa biological activity is modulated by and buy 1418741-86-2 functionally interacts with a number of protooncogenes. The PKCa molecules must be processed by a series of phosphorylation to attain catalytic competence. Undergoing translocation to the plasma membrane, PKCa is activated and consequently carries 1655472 out substrate phosphorylation. After this, phosphorylated PKCa resides in the cytoplasm of the cell and requires additional regulatory mechanisms to become fully catalytically active [7,16]. Therefore, PKCa protein expression might not fully represent kinase activity. In addition, immunoreactivity might not fully reflect true protein expression [31]. Further studies using kinase activity assay, immunogold labeling to identifysubcellular localization and translocation of PKCa protein, and fluorescence in situ hybridization to detect PKCa mRNA in different pathological stages of gastric carcinoma are needed to clarify the discrepant roles of protein and mRNA of PKCa. In conclusion, we demonstrated that PKCa protein is upregulated in gastric carcinoma. PKCa protein expression was statistically correlated with age, histologic type, tumor differentiation, depth of invasion, angiolymphatic invasion, pathologic stage, and distant metastasis. The PKCa protein overexpression was a significant independent prognostic factor for patients with gastric carcinoma in multivariate Cox regression analysis.AcknowledgmentsThe authors would like to thank Shu Mei Yang for her excellent statistical assistance.Author ContributionsConceived and designed the experiments: CLF.

Chronic kidney disease (CKD) may fundamentally underlie the development of cardiovascular disease (CVD) and appears to be a risk factor for CVD [1]. Patients with CKD are more likely to die of CVD than to develop end-stage renal failure [2]. CKD leads to increased levels of parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23) and decreased levels of circulating 1,25dihydroxyvitamin D (1,25D) along with hypocalcemia, hyperphosphatemia, bone disease, vascular calcification and cardiovascular morbidities collectively referred to as chronic kidney diseasemineral and bone disorder (CKD-MBD) [3,4,5]. Recent reports suggest that increased levels of FGF23 are a common manifestation of CKD that develop earlier than increased levels of phosphate or PTH [6]. Additionally, the circulating FGF23 level is independently correlated with endothelial dysfunction, possibly due to asymmetrical dimethyl arginine, an endogenous inhibitor of nitric oxide synthase [7].Soluble Klotho and Arterial Stiffness in CKDThe Klotho gene, identified as an `aging suppressor’ gene in mice, encodes a single-pass transmembrane protein that is predominantly expressed in the distal tubular epithelial cells of the kidneys, parathyroid glands and choroid plexus of the brain [8,9,10,11]. Klotho was originally identified in a mutant mouse strain that could not express the gene, which developed multiple disorders resembling human aging and had a shortened life span [10]. The aging phenotypes include atherosclerosis, endothelial dysfunction, low bone mineral density, sarcopenia, skin atrophy.S of mRNA versus the protein of PKCa.
