The phosphorylation levels of PHB and the PI3K/AKT pathway in mouse sperm after treatment with wortmannin, and in human sperm with reduced motility from infertile males, were measured using western blotting analysis as previously described.5 (link)6 (link) The following primary antibodies were used: rabbit anti-PHB pT258 (1:500, GTX55299, GeneTex); rabbit anti-PI3 Kinase p85 (1:500, #4292), rabbit anti-AKT (1:500, #4060), rabbit anti-AKT pT308 (1:500, #9275) and rabbit anti-AKT pS473 (1:500, #9272) purchased from Cell Signaling Technology; rabbit anti-PI3K p85 alpha+gamma (Phospho Y199+Y467; 1:500, ab196001) and rabbit anti-PHB (1:500, ab75766) from Abcam; mouse anti-α-tubulin (1:1000, 66031-1-Ig) and mouse anti-β-actin (1:1000, 60008-1-Ig) from Proteintech Group, Inc. (Rosemont, IL, USA). To block the interference of IgG heavy and light chains on IP lysate blotting, a specific IP secondary antibody (the VeriBlot for IP secondary antibody [horseradish peroxidase, HRP; 1:40, ab131366]) purchased from Abcam was applied to detect the bound protein in the IP lysate. Images were captured using a Fujifilm LAS-4000 Mini Luminescent Imaging Analyzer (Fuji Film, Tokyo, Japan). The band intensities were quantified with ImageJ Software (National Institutes of Health, Bethesda, MA, USA).

Cells were lysed in RIPA buffer (50mM Tris HCl, pH 7.7; 0.15M NaCl; 1mM EDTA; 1% Triton X-100) supplemented with protease inhibitors (Roche) and phosphatases inhibitors (Sigma Aldrich). Protein concentration was measured using Bio-Rad protein assay reagent (Biorad Laboratories, CA). Samples were denatured at 95°C for 10 min in loading buffer then resolved in SDS-PAGE and transferred onto nitrocellulose membranes. Membranes were then blocked in 5% non-fat milk in TBS buffer, 0.1% Tween and then immunoblotted using the following primary antibodies in the specified concentrations: anti-Nedd4l (13690-1-AP, rabbit, Proteintech, 1:1000), anti-Actin (mouse, IGBMC, 1:1000), anti-Akt-pS473 (#4060, rabbit, Cell Signalling, 1:1000), rabbit anti-Akt-pT308 (#2965, rabbit, Cell Signalling, 1:1000) anti-Akt (pan) (#4691, rabbit, Cell Signalling, 1:1000), p-S6S236/236 (#2211, rabbit, Cell Signalling, 1/1000), anti-S6 (#2217, rabbit, Cell Signalling, 1:1000), anti-Ub (sc-8017, mouse, Santa Cruz, 1:250), anti-V5 (R96025, mouse, Invitrogen, 1:5000). All WB experiments consist of at least 3 independent replicates.

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.
