In Vitro	Norgestrel (20 µM; 24 hours; 661W cells) treatment significantly increases cellular viability after serum deprivation and so it is demonstrated that Norgestrel is neuroprotective to stressed 661W cells[1]. Norgestrel (20 µM; 24 hours; 661W cells) treatment decreases apoptotic induced cleavage of PARP and caspase-3[1]. Norgestrel (20 µM; 6 hours; 661W cells) treatment bFGF is results in a significant upregulation of bFGF mRNA in photoreceptor cells[1]. Cell Viability Assay[1] Cell Line: 661W cells Concentration: 20 µM Incubation Time: 24 hours Result: Significantly increased cellular viability after serum deprivation. Western Blot Analysis[1] Cell Line: 661W cells Concentration: 20 µM Incubation Time: 24 hours Result: Decreased apoptotic induced cleavage of PARP and caspase-3. RT-PCR[1] Cell Line: 661W cells Concentration: 20 µM Incubation Time: 6 hours Result: A significant upregulation of bFGF mRNA over 1 hour.
In Vivo	Norgestrel (100 mg/kg; intraperitoneal injection; for 6, 24 or 48 hours; Balb/c mice) treatment can prevent light-induced ROS in photoreceptor cells, and subsequent cell death. Norgestrel acts via post-translational modulation of the major antioxidant transcription factor Nrf2; bringing about its phosphorylation, subsequent nuclear translocation, and increases levels of its effector protein superoxide dismutase 2 (SOD2)[2]. Animal Model: Balb/c mice are born into and maintained in dim cyclic light[2] Dosage: 100 mg/kg; Administration: Intraperitoneal injection; for 6, 24 or 48 hours Result: Increased expression and activation of Nrf2 via phosphorylation on serine 40, increased expression of its target antioxidant superoxide dismutase 2 (SOD2), and reduced mitochondrial oxidative stress.
