PGE2 induces COX-2 expression in podocytes via the EP4 receptor through a PKA-independent mechanism by Faour, Wissam

“…In the present study we further delineate the signaling pathways regulating podocyte COX-2 induction. Time course experiments carried out in conditionally-immortalized mouse podocytes revealed that PGE2 transiently increased phosphorylated p38 MAPK levels at 10 min, and induced COX-2 protein expression at 4 h. siRNA-mediated knockdown of EP4 receptor expression, unlike treatment with the EP1 receptor antagonist SC 19220, completely abrogated PGE2-induced p38 phosphorylation and COX-2 upregulation suggesting the involvement of the EP4 receptor subtype. …”

Metals in the Environment: Toxic Metals Removal by Muataz A. Atieh (14152746)

“…Water contamination with these compounds is becoming one of the most serious environmental problems because of the toxic nature of the heavy metal ions, even at low trace levels. With the rapid development of industries such as metal plating facilities, mining operations, tanneries, fertilisers, and paper industries, heavy metals wastewaters are directly or indirectly discharged into the environment increasingly. …”
