GLIS1 Activators

GLIS1, or Gli-similar 1, can be activated by a variety of chemical compounds, each exerting their influence through distinct mechanisms. Retinoic acid directly activates GLIS1 by binding to retinoic acid receptors, initiating a signaling cascade that enhances GLIS1 activity. Forskolin enhances GLIS1 activity by activating adenylate cyclase, leading to increased levels of cyclic adenosine monophosphate (cAMP) and subsequent GLIS1 activation. Resveratrol activates GLIS1 by triggering the activation of AMP-activated protein kinase (AMPK), a key regulator of cellular energy homeostasis. Curcumin increases GLIS1 activity by inhibiting glycogen synthase kinase-3β (GSK-3β), removing its inhibitory influence on GLIS1.

Epinephrine activates GLIS1 by binding to β-adrenergic receptors, while lithium chloride enhances GLIS1 activity by inhibiting GSK-3β. Sodium valproate activates GLIS1 by modulating the protein kinase C (PKC) pathway, and indomethacin enhances GLIS1 activity by inhibiting cyclooxygenases (COX). JQ1 activates GLIS1 by inhibiting bromodomain-containing protein 4 (BRD4), while SB431542 enhances GLIS1 activity by inhibiting transforming growth factor-β (TGF-β) signaling. ML264 activates GLIS1 by inhibiting Krüppel-like factor 5 (KLF5), and PGE2 activates GLIS1 through the prostaglandin E2 (PGE2) pathway. Finally, genistein enhances GLIS1 activity by inhibiting tyrosine kinases.
