    Abstract

    MRTF-A Gain-of-Function in Mice Impairs Homeostatic Renewal of the Intestinal Epithelium

    Researchers suggested that activated myocardin-related transcription factor A (MRTF-A) in the intestinal epithelium shifted the balance between proliferation, differentiation, and apoptosis.

    Luteolin Exhibits Synergistic Therapeutic Efficacy with Erastin to Induce Ferroptosis in Colon Cancer Cells through the HIC1-Mediated Inhibition of GPX4 Expression

    Investigators examined the synergistic therapeutic impact of combining erastin with a bioactive flavonoid compound luteolin on the ferroptosis-mediated suppression of colon cancer. Human colon cancer HCT116 and SW480 cells were used for the in vitro studies and a xenograft of colon cancer model.
