Reduced stress defense in heme oxygenase 1-deficient cells.

Stressed mammalian cells up-regulate heme oxygenase 1 (Hmox1; EC 1.14.99.3), which catabolizes heme to biliverdin, carbon monoxide, and free iron. To assess the potential role of Hmox1 in cellular antioxidant defense, we analyzed the responses of cells from mice lacking functional Hmox1 to oxidative challenges. Cultured Hmox1(-/-) embryonic fibroblasts demonstrated high oxygen free radical prod...

Heme oxygenase: colors of defense against cellular stress.

The discovery of the gaseous molecule nitric oxide in 1987 unraveled investigations on its functional role in the pathogenesis of a wide spectrum of biological and pathological processes. At that time, the novel concept that an endogenous production of a gaseous substance such as nitric oxide can impart such diverse and potent cellular effects proved to be very fruitful in enhancing our underst...

Homocysteine Induces Heme Oxygenase-1 Expression via Transcription Factor Nrf2 Activation in HepG2 Cells

Background: Elevated level of plasma homocysteine has been related to various diseases. Patients with hyperhomocysteinemia can develop hepatic steatosis and fibrosis. We hypothesized that oxidative stress induced by homocysteine might play an important role in pathogenesis of liver injury. Also, the cellular response designed to combat oxidative stress is primarily controlled by the transcripti...

Heme Oxygenase-1 Deletion Affects Stress Erythropoiesis

BACKGROUND Homeostatic erythropoiesis leads to the formation of mature red blood cells under non-stress conditions, and the production of new erythrocytes occurs as the need arises. In response to environmental stimuli, such as bone marrow transplantation, myelosuppression, or anemia, erythroid progenitors proliferate rapidly in a process referred to as stress erythropoiesis. We have previously...

Disrupted postnatal lung development in heme oxygenase-1 deficient mice

BACKGROUND Heme oxygenase (HO) degrades cellular heme to carbon monoxide, iron and biliverdin. The HO-1 isoform is both inducible and cyto-protective during oxidative stress, inflammation and lung injury. However, little is known about its precise role and function in lung development. We hypothesized that HO-1 is required for mouse postnatal lung alveolar development and that vascular expressi...
