Retinoids and carotenoids as inhibitors of carcinogenesis and inducers of cell-cell communication
Article Abstract:
The anticarcinogenic effect of retinoids and carotenoids is studied by applying weekly doses to mouse fibroblasts exposed to 3-methylcholanthrene in vitro to produce sarcoma. Suppression of the promotion stage of carcinomatous transformation is seen thus showing that retinol is chemopreventive and not chemotherapeutic. A similar effect is seen in carotenoids but these compounds have more variable tissue levels than retinoids. Retinoids and caroteinoids can prevent the progression of cancer by enhancing cell gap junctions and increasing synthesis of the junctional protein connexin, thus improving cell to cell communication which is needed for normal cell homeostasis.
