Whole-cell lysates were homogenized in modified RIPA buffer14 (link) and assayed by immunoblot as previously described14 (link). The primary antibodies against FKBP51 (rabbit polyclonal; Novus Biological), FKBP51s13 (link) and CD274/PD-L1 (rabbit polyclonal; Novus Biological) were used diluted 1:2500. CD133 (rabbit polyclonal; Abcam; Cambridge, UK) was used diluted 1:1000. A further antibody Pdcd-1L1 (rabbit polyclonal, Santa Cruz Biotechnology; Santa Cruz, CA, USA) was used for PD-L1 detection at the 1:1000 dilution. Antibody against M2-Flag, caspase-7 and γ-Tubulin (mouse monoclonal; Sigma-Aldrich, St. Louis, MO, USA) were used diluted 1:5000. Anti β-Actin-Peroxidase (mouse monoclonal; Sigma-Adrich) was used diluted 1:10000. Anti-phospho-Akt (Ser473), Akt1/2/3, phosphor-S6 kinase, G3PDH and Sox-2 (rabbit monoclonal; Cell Signaling, Danvers, MA, USA) were used diluted 1:1000. Anti-p70S6 kinase (rabbit polyclonal; Santa Cruz) was used diluted 1:500.

Phosphorylated proteins were prepared from skeletal muscle cryosections with some modifications according to the previous report (Yonekawa et al., 2014 (link)). Proteins were extracted in 1% Triton X-100/Tris buffered saline in the presence of 1 mM Na3VO4, 10 mM NaF and protein inhibitor cocktail (Roche). SDS-PAGE was done following Laemmli's method. Membranes were incubated with the following antibodies: anti-collagen VI (Santa Cruz, 1:250), anti-tubulin (Sigma, 1:250), anti-Akt1 (CST, 1:1000), anti-S473 phosphoAkt (CST, 1:200), anti-p70S6 kinase (Santa Cruz, 1:200), anti-S411 phosphoS6 kinase (Santa Cruz, 1:200), and anti-T421/S424 phosphoS6kinase (Santa Cruz, 1:200). After washing, membranes were incubated in appropriate HRP-labeled secondary antibodies, washed, and then made to react with Immobilon Western Chemiluminescent HRP Substrate. Detection and quantification of band intensities were done by ImageQuant LAS 4000 system (GE healthcare).

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.
