IHC staining of tumors was performed as described previously [13 (link)]. Primary antibodies were HK2 (Proteintech #22029-1-AP, China), HK2 (Proteintech #66974-1-Ig, China), AIMP2 (Proteintech #10424-1-AP, China), Ki-67 (Cell Signaling Technology #9449, America), Cyto c (Proteintech #10993-1-AP, America), PCNA (Abclonal #a0264, China), LC3 II (Proteintech #18725-1-AP, China), CD8 (Abcam #ab217344), CD163 (Proteintech #16646-1-AP, China), CD206 (Cell Signaling Technology #24595, American). Staining intensity was independently evaluated by two senior pathologists. The immunohistochemical score was calculated based on the positive reaction area and the intensity of staining. Each group quantified at least five different views.

Caffeic acid phenethyl ester (CAPE) and caffeic acid para-nitro phenethyl ester (CAPE-pNO2) were synthesized by methods described in the literature [44 ]. Dulbecco’s modified Eagle’s medium-high glucose (DMEM-H) culture medium, fetal bovine serum (FBS), penicillin, streptomycin, dimethyl sulfoxide (DMSO), trypsin-EDTA, Hoechst 33342, albumin from bovine serum (BSA), diaminobenzidine (DAB), hematoxylin, eosin, TUNEL kit, and 3-[4,5-dimethyl-2-thiazolyl]-2,5-diphenyl-2-tetrazolium bromide (MTT) were purchased from Sigma chemicals (St. Louis, MO). HPLC grade methanol, formic acid, acetonitrile and trichloromethane were purchased from Fisher Scientific (Fair Lawn, NJ, USA). Hela, Siha and H9c2 cell lines were obtained from Shanghai Cell Collection (Shanghai, China). Primary and secondary antibodies of P21Cip1, pro-caspase-9, β-actin, Bax, Bcl-2, CytoC, cleaved caspase-3, pro-caspase-3, cyclin B1, Cdc2, VEGF, and secondary antibody (HRP marked) were purchased from Proteintech Group Inc. (Wuhan, China). All other reagents were of analytical grade and were used without further purification.

Western Blot Analysis of Cellular Proteins

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total proteins were extracted by RIPA buffer (Beyotime, China), lysed from cells or tissues with the addition of protease inhibitors (1:100, CWBIO) and phosphatase inhibitors (1:100, CWBIO), separated by 10% SDS PAGE or 12% SDS PAGE, and then transferred onto PVDF membranes. After incubation with primary antibodies overnight at 4 °C, membranes were washed three times with PBST. These blots were incubated with HRP-conjugated secondary antibody (Proteintech #SA00001-2, America) for 1.5 h at 4 °C. The blots were washed three times with PBST and visualized by enhanced chemiluminescence (Tanon ECL, China). Primary antibodies used for western blot were listed as follows: GAPDH (Proteintech #10494-1-AP, China), HK2 (Proteintech #22029-1-AP, China), AIMP2 (Proteintech #10424-1-AP, China), Cyto c (Proteintech #10993-1-AP, China), Caspase 3/p17/p19 (Proteintech #19677-1-AP, China), Bcl-xL (Abcam #ab32370, America), LC3 (Proteintech #14600-1-AP, China), P62 (Proteintech #18420-1-AP, China), Becline1 (Proteintech #11306-1-AP, China).

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.
