1 Modulatory effects of progesterone on inducible nitric oxide synthase expression in vivo and in vitro. Progesterone nitric oxide synthase 2, inducible Mus musculus
2 Previous studies investigating the therapeutic potential of female sex steroids in stroke and trauma suggest that NO from this source is harmful, since oestradiol and progesterone decreased the level of iNOS expression in vitro and improved neurological outcome. Progesterone nitric oxide synthase 2, inducible Mus musculus
3 We observed a significant reduction in stroke-induced iNOS transcript in progesterone-treated mice and in cultured macrophages. Progesterone nitric oxide synthase 2, inducible Mus musculus
4 Astrocytes transiently transfected with iNOS promoter/CAT reporter gene constructs containing the PRE displayed a significant increase in induction of CAT expression after progesterone treatment, and this was diminished in cells transfected with a construct containing a disrupted PRE. Progesterone nitric oxide synthase 2, inducible Mus musculus
5 These observations suggest the involvement of iNOS in the neuroprotective effects of progesterone. Progesterone nitric oxide synthase 2, inducible Mus musculus
