Cystathionine beta synthase (CBS) Over expression vs PLenti6 Expression Vector Human Bronchial Epithelial Cells (HBEC)
Ontology highlight
ABSTRACT: Cystathionine Beta Synthase (CBS), an enzyme that utilizes a methionine precursor to generate glutathione (GSSH), has been implicated in the mitigation of ROS production in COPD lung. Additionally, post-translational modification analysis on mouse and human cells treated with cigarette smoke showed the unique presence of mono- and di-methylated histone H3 lysine 27 that was not seen in controls, suggesting that cigarette smoke could lead to loss of Polycomb Repressive Complex 2 (PRC2) activity. To elucidate CBS as a potential upstream target for PRC2 inhibition, we overexpressed CBS in Human Bronchial Epithelial Cells (HBECs), grew them as 2D cultures, then conducted bulk RNA seq analysis.
