For immunoprecipitation (IP), whole-cell extracts were lysed in an IP buffer composed of 1% (vol/vol) NP-40, 150 mM NaCl, 1 mM EDTA, 50 mM Tris-HCl (pH 7.5) and the complete protease inhibitor cocktail (Roche). Cell lysates were collected and incubated with 1 μg of the corresponding antibodies together with protein G Plus-Agarose Immunoprecipitation reagent (Santa Cruz). After overnight incubation at 4 °C, agaroses were washed five times and boiled with the IP buffer for SDS-PAGE. For immunoblotting analysis, cells were lysed with a lysis buffer (150 mM NaCl, 1 mM EDTA, 1% Triton X-100 and 50 mM Tris-HCl, pH 7.5) supplemented with the protease inhibitor cocktail (Roche), and were incubated with the following antibodies: anti-FLAG (Proteintech, 20543-1-AP), anti-HA (Proteintech, 51064-2-AP), anti-His (Proteintech, 66005-1-lg), anti-RIP1 (Santa Cruz, sc-133102), anti-RIP3 (Santa Cruz, sc-374639), anti-RIP1(Santa Cruz, sc-133102), anti-Myc (Proteintech, 67447-1-Ig), anti-pRIP3 (Abcam, ab205421), anti-mouse pMLKL (Abcam, ab196436), anti-human pMLKL (Abcam, ab206336), anti-MLKL (Abcam, ab243142), anti-Actin (Abcam, ab8226), and anti-TRIM25 (Abcam, ab167154).

To evaluate the effect of CIS and AZM on RIP1, RIP3, MLKL, and caspase-8, 50 µg protein was subjected to SDS-PAGE followed by transfer onto PVDF membranes. Then, 5% BSA was used for blocking, and the membranes were then incubated with anti-RIP1 (sc-133102—Santa Cruz, Dallas, TX, USA), anti-RIP3 (sc-374639—Santa Cruz, Dallas, TX, USA), anti-MLKL (YPA2507—Biospes, Chongqing, China), anti-caspase-8 (sc-70501—Santa Cruz, USA), and anti-β-actin (sc-8432—Santa Cruz, Dallas, TX, USA) overnight at 4 °C. After washing in TBST, the membranes were incubated with the secondary antibodies for 1 h at RT, washed and visualized using the BCIP/NBT substrate detection kit (GeneMed Biotechnologies, San Francisco, CA, USA). The intensity of the developed bands was determined using ImageJ (NIH, Bethesda, MD, USA).

DHQ3 and 17-DR were obtained as described previously. They were dissolved in dimethyl sulfoxide (DMSO, Biosharp, Hefei, China) and stored at −20 °C. MG132, Nec-1, DAPI (4,6-diamidino-2-phenylindole), and 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) were purchased from Sigma-Aldrich (St. Louis, MO, USA). PI assay kits were purchased from Beyotime Institute of Biotechnology (Wuhan, China) and the Annexin V FITC/PI apoptosis detection kit was purchased from Nanjin KeyGen Biotech (Nanjing, China). The ATP Assay kit was purchased from Merck KGaA (Darmstadt, Germany). Lipofectamine 2000 was purchased from Invitrogen (USA). The following antibodies were used: anti-Mcl-1, anti-PARP, anti-RIP1, anti-RIP3 (Santa Cruz Biotechnology, Santa Cruz, CA, USA); anti-Bcl-2, anti-Bax, anti-HIF1a, anti-CDK4, anti-Her2, anti-EGFR (Proteintech, Chicago, IL, USA); anti-Hsp70, anti-Hsp90, anti-Akt (Cell Signaling Technology, Beverly, Massachusetts, USA); anti-caspase 3 and anti-caspase 8 (ENZO, Switzerland); anti-C-Raf (Abcam, Cambridge, MA, USA); and anti-β-actin (BioSharp, Hefei, China).

Whole cell or tissue samples were homogenized in RIPA buffer (Santa Cruz Biotechnology, Inc., Dallas, TX) with protease inhibitor cocktail (Thermo Scientific) and 40 μg total protein was used for immunoblot analysis according to our previous protocols [27] . Blots were probed with anti-Klotho (1:200; Thermo Scientific), anti-3-nitrotyrosine (1:500; Abcam, Cambridge), anti-SOD2 (1:500; Santa Cruz Biotechnology), anti-RIP1 (1:100; Santa Cruz Biotechnology), anti-RIP3 (1:500; Santa Cruz Biotechnology), anti-IL-1 beta (1:1000; Abcam), anti-tubulin (1:1000; Abcam), anti-beta-actin (1:2000; Abcam), anti-catalase (1:1000; Abcam), anti-GPX4 (1:1000; Abcam), anti-t-FoxO1 (1:1000; Cell Signaling Technology, Beverly, CA), antip-FoxO1 (1:1000; Cell Signaling Technology), anti-t-FoxO3a (1:1000; Cell Signaling Technology), anti-p-FoxO3a (1:1000; Cell Signaling Technology), or anti-GAPDH (1:1000; Cell Signaling Technology) antibodies overnight at 4 °C. After washing, the membranes were incubated with the appropriate horseradish peroxidase-conjugated secondary antibody (1:5000; Cell Signaling Technology). After washing, specific signals were determined using an ECL kit (Thermo Scientific) on a Tanon 5200 Chemiluminescent Imaging System (Tanon, Shanghai). Gray values were analyzed with ImageJ software.

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.
