Dnmt2 is a highly conserved methyltransferase of uncertain biological function(s). As Dnmt2 was considered as a driver of fruit fly longevity and a modulator of stress response, we decided to evaluate the role of Dnmt2 during stress‐induced premature senescence in NIH3T3 mouse fibroblasts. Stable knockdown of Dnmt2 resulted in hydrogen peroxide‐mediated sensitivity and apoptosis, whereas in the control...
Plant-derived pentacyclic triterpenotids with multiple biological activities are considered as promising candidates for cancer therapy and prevention. However, their mechanisms of action are not fully understood. In the present study, we have analyzed the effects of low dose treatment (5–20 µM) of ursolic acid (UA) and betulinic acid (BA) on breast cancer cells of different receptor status, namely...
Relatively low bioavailability of plant-derived nutraceuticals with anticancer properties may limit their usefulness for prevention and therapy of cancer. In the present study, we have screened for nutraceuticals (n=30) that would act at low micromolar range against phenotypically distinct breast cancer cell lines, namely MCF-7 (ER+, PR+/−, HER2−), MDA-MB-231 (ER−, PR−, HER2−) and SK-BR-3 (ER−, PR...
