Ozone (O3) is a primary component of photochemical smog and represents a serious public health concern as more than 50% of the U.S. population lives in areas exceeding national ambient air quality standards for this toxic pollutant. Recent findings indicate that the effects of inhaled O3 extend to extra-pulmonary tissues like the heart and liver. We hypothesize that inhaled O3 exposure-related events in the lung will cause downstream alterations in the liver proteome. To test this, we exposed male Sprague-Dawley rats to 0.5 ppm ozone for 8 hr a day for 5 days. After exposures, livers were removed and proteomic …

Regulation Of Neuronal Cell Death By Bh3-Only Proteins, Arindam P. Ghosh

Apoptosis in metazoan organisms plays critical roles in normal development, tissue homeostasis and immunity, and its disturbed regulation leads to many pathological states, including cancer, autoimmunity, infection and degenerative disorders. Apoptosis can be triggered by the engagement of `death receptors' of the tumor necrosis factor receptor family on the cell surface or by diverse intracellular signals that act upon the BCL2 (B-cell CLL/lymphoma 2) protein family, which controls the integrity of the mitochondrial outer membrane through the complex interactions of family members. Both the pathways lead to cellular demolition by dedicated proteases termed caspases. Different BH3-only proteins (or combinations of …
