MedChemExpress erk1 2 activator msirk
Siglec-5 induces through the <t>HSF1/SYK/ERK1/2/SIRPα</t> signaling pathway. ( A) Western blot for detecting Siglec5, HSF1, NLRP3, p-SYK, p-ERK, p-ELK1, SIRPα, p-SHP2, and NOX4 protein expression. (B) Data statistics. Relative protein expression was quantified by densitometry using ImageJ and normalized to corresponding internal reference proteins (e.g., GAPDH or total protein). Data represent mean ± SD from three independent experiments. (C) CO-IP experiments confirmed the interaction; (C) Co-IP assays verified the interactions between Siglec5/HSF1 and ELK1/SIRPa.
