Phosphorylation of aortic endothelial nitric oxide synthase (eNOS) increased with 10 µg/kg A2 alone or co-treatment with 100 µg/kg A2 and yohimbine, but not with co-treatment of 10 µg/kg A2 and carvedilol or 100 µg/kg A2 alone. These results imply that A2 does not directly activate eNOS but that shear stress from the increased BF might be associated with eNOS phosphorylation.Background The purpose of this study was to identify the expression of phosphatase and tensin homolog (PTEN) and its diagnostic value in colorectal cancer (CRC).Methods The expression level of serum PTEN at mRNA and protein level were determined using quantitative real-time polymerase chain reaction (qRT-PCR) and Western blot analyses, respectively. Chi-square test was employed to explore the relationship between PTEN expression and clinical features of CRC patients. The receiver operating characteristics (ROC) curve was established to evaluate the diagnostic performance of PTEN in CRC.Results The expression of serum PTEN was significantly lower in patients with CRC than that in healthy controls both at mRNA and protein level (p  less then  .05). Also, the low PTEN expression was significantly related to serosal invasion, lymph node metastasis and Ki-67, but had no relation with age, sex, tumor depth and tumor site. The area under ROC curve of 0.810 corresponding with a sensitivity of 97.79% and a specificity of 70.31% were obtained, which suggested PTEN could act as a diagnostic marker for CRC.Conclusion Altogether, serum PTEN expression was down-regulated and it participated in the development of CRC. Besides, it could act as an efficient and independent diagnostic marker for CRC patients.Cyclosporine-A (CsA) is a widely used immunosuppressant. In this study, we explore the pathway through which CsA suppressed the Porphyromonas gingiv
