Six weeks of isotretinoin treatment caused a statistically significant 19% increase in suction blister fluid TGF-beta1. [2] Glycosylphosphatidylinositol (GPI)-anchored proteins have been demonstrated to bind transforming growth factor-beta (TGF-beta) in certain cell lines. GPI-anchored protein(s) are suggested to inhibit TGF-beta signaling and implicate r150 as the GPI-anchored protein responsible for this inhibition in human keratinocytes [1]. TGF-beta1 was found to significantly down-regulate IP3R protein expression in mesanglial cells[5].
mRNA levels of the type 1 IP3 receptors were found to be decreased significantly in cerebellum and hypothalamus, but not in the brain stem of rats treated with retinoic acid, compared to untreated littermates. The mRNA levels of the type 2 IP3 receptor were significantly decreased in all tested tissues, cerebellum, hypothalamus, and also in brain stem after the treatment with retinoic acid. These results show that gene expression of both type 1 and 2 IP3 receptors is regulated by retinoic acid, although the effect of retinoic acid on mRNA levels of the type 1 IP3 receptors is dependent on brain area.

IP(3) receptor channel clusters control Ca(2+) intracellular release from the endoplasmic reticulum (ER) to the cytosol in various cells and species. [3]
