EXOSC8 Activators

EXOSC8 activators include diverse chemical compounds that indirectly bolster the functional activity of EXOSC8 by modulating various signaling pathways and molecular interactions. Forskolin, with its ability to elevate intracellular cAMP, along with Rolipram and IBMX, which also increase cAMP by inhibiting phosphodiesterases, activate PKA that could phosphorylate and influence factors associated with the RNA exosome complex where EXOSC8 is critical for RNA degradation. Resveratrol, by activating SIRT1, and Nicotinamide, through its inhibition of sirtuins, may alter the acetylation status of proteins that interact with the RNA exosome complex, optimizing EXOSC8's role in RNA turnover.

Epigallocatechin Gallate and Curcumin, through kinase inhibition and AMPK activation respectively, affect pathways that are crucial for mRNA decay, impacting EXOSC8's function. Retinoic Acid's modulation of gene expression and Sodium Butyrate's histone deacetylase inhibition can alter the expression and modification state of RNA exosome cofactors, which may indirectly amplify EXOSC8's activity. Zinc's role in protein folding and function could stabilize the RNA exosome complex structure, thus supporting EXOSC8's RNA degradation activity. Lastly, Caffeine, another phosphodiesterase inhibitor, and Nicotinamide, with its sirtuin inhibition, can modulate post-translational modifications of proteins within the RNA exosome complex, enhancing EXOSC8's function. Together, these activators contribute to the regulatory landscape of EXOSC8, ensuring its efficient role in RNA metabolism without directly upregulating its expression or activity.
