Cell extracts were prepared using RIPA buffer (20mM Tris, pH 7.4, 137 mM NaCl, 1% NP-40, 0.25% Deoxycholate, 0.1% SDS, 1mM EDTA and 1% protease inhibitor cocktail). Protein concentration was determined by BCA kit (Pierce; Rockford, IL) and 100 µg protein was analyzed by Western blotting as described previously69 (link). Anti-p53 (sc-98, Santa Cruz) was used at 1:1000 (2 µg/mL) dilution and anti-Bcl-2 (sc-492, Santa Cruz) and anti-β-actin (Sigma) were used at 1:1000 dilutions. SPDEF antibodies (gift from Dr. Jeffery Whitsett, Children’s Hospital, University of Cincinnati, OH) were used at 1:5000 dilution. Proteins were detected using ECL and visualized by chemiluminescence (Perkin Elmer, Waltham, MA) using the FujiFilm Image Reader LAS-4000 (Valhalla, NY). The uncropped scans of the most important Western blots are included as a supplementary figure in the Supplementary Information.

Cells were lysed with the M-PER mammalian protein extraction reagent (Thermo Scientific, Rockford, IL) containing a protease inhibitor cocktail (Nacalai Tesque). Equal amounts of protein were resolved on 4–12% gradient or 12% SDS-PAGE gels, followed by transfer to polyvinylidene fluoride membranes. After blocking membranes, blots were incubated with the indicated primary antibodies: anti-Bcl-2 (sc-492; Santa cruz biotechnology [SCB], Dallas, Texas, USA, anti-Bcl-XS/L (#633901; BioLegend, San Diego, CA, USA ), anti-Mcl-1 (sc-819; SCB ), anti-caspase-3 (9668; Cell Signaling Technology [CST], Danvers, MA, USA ), anti-caspase-8 (M032-3; Medical and Biological Laboratories, Nagoya, Japan), anti-caspase-9 (9508; CST), anti-β-actin (BioLegend ) or anti-α-tubulin (SCB). After washing, room temperature incubation of membranes for 30 min with either goat anti-rabbit or goat anti-mouse alkaline phosphatase-conjugated secondary antibodies (Invitrogen) were used to detect the primary antibodies. Protein bands were visualized using an ImageQuant LAS-4000 system (FujiFilm, Tokyo, Japan).

Cells were lysed with radioimmunoprecipitation assay buffer (Beyotime, Shanghai, China). After the protein concentration was determined with BCA protein assay kit (Thermo Fisher Scientific), equal protein aliquots (25 μg per lane) were resolved on SDS gel electrophoresis and Western blotting assay was performed with standard protocol. The expression of target proteins was detected by using enhanced chemiluminescence system (Bio-Rad, Richmond, CA, USA) and quantified by densitometry with Image J software (http://rsb.info.nih.gov/ij/, Bethesda, MD, USA). Protein expression was normalized by the loading control (GAPDH) expression. Antibodies against FAM46C (ab169699), CDK1 (ab32384), XIAP (ab2541) and Ras (ab52939) were purchased from Abcam (Cambridge, MA, USA). Anti-Bcl-2 (sc-492) and anti-Bax (sc-493) were from Santa Cruz Biotech. (Santa Cruz, CA, USA). Antibodies against Cyclin B1 (#4135), PCNA (#13110), p-MEK1/2 (#8211), MEK1/2 (#9122), p-ERK1/2 (#4376), ERK (#4695) and GAPDH (#5174) were purchased from Cell Signaling (Danvers, MA, USA).

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.
