    Abstract

    Estrogen-Related Receptor Alpha Directly Binds to p53 and Cooperatively Controls Colon Cancer Growth through the Regulation of Mitochondrial Biogenesis and Function

    Researchers designed in vitro and in vivo studies to investigate the possibility of targeting colon cancers that exhibit defects in p53.

    Thermal Processing Has No Impact on Chemopreventive Effects of Oat and Barley Kernels in LT97 Colon Adenoma Cells

    Growth inhibition, apoptosis, DNA integrity and gene expression of catalase were analyzed in LT97 colon adenoma cells. Concentrations of short-chain fatty acids, particularly butyrate, were higher in oat/barley fermentation supernatants, while ammonia levels were significantly lower than in the fermentation control.
