Antioxidant Supplements: A Promising Approach to improving COVID-19 Demonstrations

Severe acute respiratory syndrome-coronavirus 2 (SARS-CoV-2) that causes COVID-19 could progress to acute respiratory distress syndrome (ARDS). The immune cells' migration in response to virus lead to cell death by releasing oxidizing free radicals. These oxidizing free radicals mediate NF-κB activation and induce transcription of cytokine-producing genes that eventually a cytokine storm ensues...

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...

CuO nanoparticles induce cytotoxicity and apoptosis in human K562 cancer cell line via mitochondrial pathway, through reactive oxygen species and P53

Objective(s): This study focused on determining cytotoxic effects of copper oxide nanoparticles (CuO NPs) on chronic myeloid leukemia (CML) K562 cell line in a cell-specific manner and its possible mechanism of cell death. We investigated the cytotoxicity of CuO NPs against K562 cell line (cancerous cell) and peripheral blood mononuclear cell (normal cell). Materials and Methods: The toxicity w...

NQO1 stabilizes p53 through a distinct pathway.

Wild-type p53 is a tumor-suppressor gene that encodes a short-lived protein that, upon accumulation, induces growth arrest or apoptosis. Accumulation of p53 occurs mainly by posttranslational events that inhibit its proteosomal degradation. We have reported previously that inhibition of NAD(P)H: quinone oxidoreductase 1 (NQO1) activity by dicoumarol induces degradation of p53, indicating that N...
