We analyzed the expression and clinical significance of δ-catenin in non-small cell lung cancer (NSCLC) and investigated prognosis using human lung cancer samples. Eighty-nine NSCLC patients underwent operation between January and March 2009. There were 53 cases of squamous cell carcinoma, 31 adenocarcinoma, and 5 large cell carcinoma. δ-Catenin in NSCLC patients was detected by immunohistochemistry and analyzed in combination with the clinicopathological characteristics of lung cancer.
To explore the role of metalloproteinase-1 (TIMP-1) tissue inhibitor in the mechanisms of kidney aging, we observed the effects of sense and antisense transfection of TIMP-1 and of metalloproteinase (MMP) inhibitors on phosphatase and tensin homolog (PTEN), vascular endothelial growth factor (VEGF), and Flk-1 expression in TIMP-1 transgenic human proximal tubular epithelial cells (HKCs). Transfected HKCs were co-incubated with 100 μM MMP-2 and MMP-9 inhibitor III for 24 h to affect enzyme inhibition.
