Figure Lengend Snippet: Docosahexaenoic acid (DHA) promotes myoblast proliferation in grass carp via cluster of differentiation 36 (CD36) and CAV1. (A) Protein levels of CAV1 expression in myoblasts treated with CAV1 inhibitor. (B) Quantitative results of CAV1 protein levels in myoblasts treated with CAV1 inhibitor. (C) Percentage of 5-ethynyl-2′-deoxyuridine (EdU)-positive myoblasts relative to the total myoblasts. (D) EdU (red fluorescence) and Hoechst (blue fluorescence, nuclei) staining. Scale bar, 200 μm. (E and F) The mRNA expression levels of proliferation-related genes (cyclin D1 and cyclin E) in myoblasts treated with DHA for 24 h. (G) Overexpression of cav1 in myoblasts. Control, untreated; DHA, treated with 50 μmol/L DHA; DHA + Nys, co-treated with 50 μmol/L DHA and 75 μmol/L Nys; DHA + Nys + SSO, co-treated with 50 μmol/L DHA, 75 μmol/L Nys, and 200 μmol/L SSO; CAV1 OE, myoblasts were transfected with a CAV1-overexpression plasmid; DHA + CAV1 OE, CAV1-overexpressing myoblasts were treated with 50 μmol/L DHA. SSO = sulfosuccinimidyl oleate sodium (a CD36 inhibitor); Nys = nystatin (a CAV1 inhibitor); CAV1 OE = CAV1-overexpressing; GAPDH = glyceraldehyde-3-phosphate dehydrogenase. P -value less than 0.05 indicates a significant difference, n = 3.
Article Snippet: To investigate whether DHA promotes myoblast proliferation via the CD36-mediated absorption pathway, this study utilized DHA (HY-B2167) and the CD36 inhibitor sulfosuccinimidyl oleate sodium (SSO; HY-112847A), both from MedChem Express LLC (Monmouth Junction, NJ, USA).
