Cell cycle arrest by kynurenine in lens epithelial cells.
PURPOSE Indolemine 2,3-dioxygenase (IDO)-mediated oxidation of tryptophan produces kynurenines (KYNs), which may play a role in cataract formation. The molecular mechanisms by which KYNs cause cellular changes are poorly understood. The effects of KYNs on mouse lens epithelial cells by overexpression of human IDO were investigated. METHODS Lens epithelial cells (mLECs) derived from human IDO-...
متن کاملSonic Hedgehog Opposes Epithelial Cell Cycle Arrest
Stratified epithelium displays an equilibrium between proliferation and cell cycle arrest, a balance that is disrupted in basal cell carcinoma (BCC). Sonic hedgehog (Shh) pathway activation appears sufficient to induce BCC, however, the way it does so is unknown. Shh-induced epidermal hyperplasia is accompanied by continued cell proliferation in normally growth arrested suprabasal cells in vivo...
متن کاملDeregulated cell cycle control in lens epithelial cells by expression of inhibitors of tumor suppressor function
Previous studies have shown that cell cycle proteins such as retinoblastoma protein (pRB) are essential for cell cycle withdrawal in differentiating lens cells. However, little is known about which factors are critical for cell cycle control in the lens epithelial cells. Here we use the K14 promoter to direct expression of E6 and E7, oncogenes from human papillomavirus type 16, which are known ...
متن کاملCell cycle arrest and inhibition of anoikis by galectin-3 in human breast epithelial cells.
Galectin-3 is a member of a growing family of animal beta-galactoside-binding proteins shown to be involved in cell growth, differentiation, apoptosis resistance, and tumor progression. In the present study, we investigated whether galectin-3 can protect against apoptosis induced by the loss of cell anchorage (anoikis). Because studies suggest that cellular sensitivity to anoikis is associated ...
متن کاملChenopodium Botrys as a Source of Sesquiterpenes to Induce Apoptosis and G1 Cell Cycle Arrest in Cervical Cancer Cells
Conducting cell apoptosis pathways is a novel strategy in cancer treatment. This study aimed to explain that C. botrys essential oil could induce apoptosis and arrest the cell cycle in HeLa cells. Cytotoxic and apoptogenic effects of the essential oil of Jerusalem-oak (Chenopodium botrys L.), which was obtained from the aerial parts of the plant, were evaluated in HeLa cells. Cell viability was...
