Nitrites 179-186 nitric oxide synthase 2, inducible Mus musculus 45-49 24599317-7 2014 Treatments increasing nitrite production also increased iNOS expression, while treatments decreasing nitrite production reduced iNOS expression. Nitrites 101-108 nitric oxide synthase 2, inducible Mus musculus 128-132 24599317-8 2014 Among the different NOS isoforms, experiments using L-748,337 or BRL37344 with activators or inhibitors targeting specific NOS isoforms demonstrated a prominent role of iNOS in nitrite production.

Nitrites 39-46 nitric oxide synthase 2, inducible Mus musculus 192-196 27623091-9 2016 Moreover, these improvement effects of methylphenidate on SAB and the nitrite level were decreased by the administration of selective iNOS and eNOS inhibitors. Nitrites 70-77 nitric oxide synthase 2, inducible Mus musculus 134-138 27526131-5 2016 Acidotic conditions for up to 6 h increased the iNOS expression significantly which was functional as indicated by an elevated level of nitrate/nitrite formation by 30 %.

Nitrites 43-50 nitric oxide synthase 2, inducible Mus musculus 9-13 16771679-10 2006 These data suggest that the human-specific release of nanomolar levels of nitrite may largely result from differences between the human and mouse NOS2 genes, which may program different degrees of nitric oxide responses to inflammatory signals in humans than in mice. Nitrites 74-81 nitric oxide synthase 2, inducible Mus musculus 146-150 16223598-4 2006 The activity of mtNOS and nitrite levels significantly increased after sepsis in iNOS+/+ mice.
