1.11.1.12 down 10 mg/l Cd2+ down-regulates gpx4b in liver and olfactory lobe tissues 1.11.1.12 down in the liver of the carp exposed to 7°C temperature drop, the gpx4a gene is down-regulated as early as 1 h after cold shock to 75% 1.11.1.12 down subarachnoid hemorrhage (SAH) reduces enzyme expression 1.11.1.12 up Bi-PHGPx transcripts are up-regulated by stresses, such as wounding, H2O2 exposure, external temperature shock, and starvation 1.11.1.12 up expression in rice seedlings can be markedly induced by H2O2 and NaCl 1.11.1.12 up in liver direct exposure to low temperature increases the transcription of gpx4b by 2.5fold 1.11.1.12 up PHGPx expression is up-regulated in spermatozoa by unknown mechanisms 1.11.1.12 up expression is increased after treatment with copper ions 1.11.1.12 up KfPHGPx expression can be markedly induced by moderate salt treatment, best at 250 mM/l
