Circulating and podocyte-bound urokinase receptor (uPAR) is a mediator of podocyte injury, proteinuria, and focal segmental glomerulosclerosis (FSGS) allowing pathological activation of the uPAR-β3 integrin signaling axis. Clinically, calcineurin inhibitors (e.g., cyclosporine A, CsA) are known to suppress T cells, yet are also being used to reduce… (More)
Our previous studies showed that prostaglandin E2 (PGE2) promotes hepatoma cell growth and migration, as well as invasion; however, the precise mechanism remains elusive. Snail and p65 protein levels were detected in human samples with hepatocellular carcinoma (HCC) by immunohistochemistry (IHC) staining. HCC cell lines (Huh-7 and Hep3B) were used for in… (More)
Cyclooxygenase-2 (COX-2) and COX-2-induced prostaglandin E2 (PGE2) have been implicated in all stages of malignant tumorigenesis. Although many aspects of matrix metalloproteinase (MMP2) on tumor invasion have been studied, the exact mechanism of PGE2-induced MMP2 overproduction has not been clearly defined. We have previously demonstrated that… (More)
BACKGROUND Accumulating studies have demonstrated that 1,25-Dihydroxyvitamin D(3) (1,25(OH)2D3) reduces proteinuria and protects podocytes from injury. Recently, urokinase receptor (uPAR) and its soluble form have been shown to cause podocyte injury and focal segmental glomerulosclerosis (FSGS). Here, our findings showed that 1,25(OH)2D3 did inhibit… (More)
Figure S1. The effects of PGE2 on cell viabilities in NSCLC cells. The cell viability assays were performed in 96-well units by CCK-8. A549, LLC and H1299 cells were treated with 5 μM PGE2. Results are presented as the mean ± SEM (n=3).
