Human phosphodiesterase 5A gene silencing device NO.1

This device is uesd for silencing the human phosphodiesterase 5A (PDE5A) gene.A U6 promoter driving a designed, synthetic shRNA-like miRNA followed by the terminator.

PDE5A is a cGMP-binding, cGMP-specific phosphodiesterase, a member of the cyclic nucleotide phosphodiesterase family. This phosphodiesterase specifically hydrolyzes cGMP to 5'-GMP. It is involved in the regulation of intracellular concentrations of cyclic nucleotides and is important for smooth muscle relaxation in the cardiovascular system.

We designed 3 silencing device and test their function at the same time.Here is the another two device :BBa_K1720004,BBaK172005

This device with a GFP reporter was then transfected into HEK293 cells by lentiviral vector.Once we silence the PDE5A gene the level of cGMP will be up regulated as a result. The positive control was HEK293 cells that treat with Sodium Nitroprusside ,a NO donator that activate sGC and up regulate the level of cGMP. A negative control was made by transfecting an empty vector that does not contain sGC subunit. We used Elisa to detect cGMP level. The results are as follow:
