Nitric Oxide 0-12 nitric oxide synthase 2, inducible Mus musculus 184-188 7530281-6 1995 Because cyclic variations suggested regulation of iNOS expression by ovarian steroid hormones, studies were done using ovariectomized mice. Steroids 77-93 nitric oxide synthase 2, inducible Mus musculus 50-54 7530281-8 1995 In the uteri of ovariectomized, estradiol-17 beta (E2)-treated mice, mast cells were iNOS+ after 24 h whereas epithelial cells were negative; the reverse was observed in progesterone (P4)-treated mice. estradiol-17 beta (e2) 32-54 nitric oxide synthase 2, inducible Mus musculus 85-89 7530281-9 1995 Both mast cells and epithelial cells were iNOS+ in the uteri of mice that had received a combination of E2 + P4. e2 + p4 104-111 nitric oxide synthase 2, inducible Mus musculus 42-46 7530281-10 1995 These results indicate that several types of uterine cells produce iNOS and that expression of this enzyme in specific cell lineages is governed by ovarian steroid hormones. Steroids 156-172 nitric oxide synthase 2, inducible Mus musculus 67-71
