ROCK

In Vitro Pentanoic acid, a short-chain fatty acid, is a product of bacterial metabolism and are associated with allergic skin disorders. Pentanoic acid (0-2 mM) strongly and dose-dependently induces thymic stromal lymphopoietin (TSLP) production in PAM212 cells. Pentanoic acid slightly induces the expression of Tnfa, Il1b and Il6 mRNA, but does not induce the protein levels of TNF-α expression. Pentanoic acid (2 mM) induced-TSLP production in keratinocytes is not related to FFAR2 and FFAR3, but mediated by activating ROCK signaling pathway, and is competetely inhibited by co-inhibition of Gq/11 and the ROCK signaling pathway[1].
Cell Assay PAM212 murine keratinocytes are derived from BALB/c mouse skin. PAM212 cells are cultured in alpha minimal essential medium containing 10% heat-inactivated fetal bovine serum, penicillin G (15 μg/mL), and streptomycin (50 μg/mL) in a humidified atmosphere of 5% CO2/95% air at 37°C. Cells seeded at 50,000 cells/mL are grown for 24 h in culture medium. Cells are stimulated with Pentanoic acid for an appropriate period. Pretreatment with Y-27632, a highly potent and selective inhibitor of Rho-associated, coiled-coil containing protein kinase (ROCK), is carried out for 1 h, whereas pretreatment with YM-254890, a specific Gq/11 inhibitor, is carried out for 30 min[1].
