All the kits or reagents for western blotting were obtained from Elabscience (Wuhan, China). Cells were lysed using the RIPA lysis buffer, and the protein concentration was estimated using the BCA Protein Concentration Detection Kit (Catalog No. E-BC-K318). SDS-PAGE (10%; Catalog No. E-IR-R305) was employed to separate proteins, which were then transferred onto PVDF membranes. The membranes were blocked for 1.5 h in 5% skim milk. The membranes were then incubated with primary antibodies (anti-ANP: ab209232, 1:1,000; anti-BNP: ab236101, 1:2,000; anti-β-MHC: ab180779, 1:2,000; and anti-β-actin: ab8227, 1:5,000; Abcam, Cambridge, CA, USA) overnight at 4°C and then incubated with secondary antibodies (Catalog No. E-AB-1003; Elabscience) for 1 h at 25°C. Protein bands were visualized using an ECL luminous detection solution (Catalog No. E-BC-R347). Gray analysis was performed by normalizing to GAPDH levels.

For GATA4, pGATA4 and BNP thirty μg and for MEF2C hundred μg of total protein from heart tissue was lysed in EBC + urea buffer (50 mM Tris-HCl pH 7.5, 150 mM NaCl, 0.5% NP-40, 3 M urea) resolved by SDS-PAGE, transferred to PVDF membrane, blotted, and probed with the following primary antibodies: anti-GATA4 pSer105 (1:600 ab5245, Abcam), anti-GATA4 (1:1000 sc-9053, Santa Cruz Biotechnology), anti-BNP (1:500 ab236101, Abcam), anti-vinculin (1:200 V4505, Merck) and anti-MEF2C (1:7500 sc-313×, Santa Cruz Biotechnology) followed by a HRP-conjugated secondary antibody (1:5000; Bio-Rad). For blotting of HIF1α and HIF-P4H-2 hundred ug of total protein from heart tissue lysed using EBC + urea lysis buffer and was resolved by SDS-PAGE, transferred with nitrocellulose membrane, blotted and probed with anti-HIF1α (1:500, NB100-479 Novus Biologicals) and anti-HIF-P4H-2 (1:500, Novus Biologicals NB100-2219)primary antibodies followed by HRP-conjugated secondary antibody. The Pierce ECL system (Ther-moScientific) was used for detection. Western blot images were quantified with fiji (ImageJ) software. For original blots see (Supplementary Fig. S1-S8).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
