Hela cells were treated with the two compounds PS 1 and PS 2. After treatment, the cells were harvested and lysed in RIPA buffer (150 mM NaCl, 1% NP-40, 0.5% sodium deoxycholate, 0.1% SDS, 50 mM Tris-HCl, pH 8.0). The total protein concentration was determined by Bio-Rad Protein Assay (Bio-Rad Laboratories, USA). The samples were separated electrophoretically using prestained SDS PAGE gels (Bio-Rad Laboratories) and transferred to a polyvinylidene fluoride (PVDF) membranes. The membranes were kept at 4°C overnight in 3% BCA (Sigma-Aldrich) in PBS/Tween-20 and then incubated with the primary antibodies at one of the following: β-actin (ab 1801, Abcam, UK), Bid (ab 32060, Abcam), Bcl-2 (ab 59348, Abcam), caspase-8 (sc-81661, Santa Cruz Biotechnology, USA). After washing with PBS/Tween-20, the membranes were incubated with goat anti-rabbit IgG or with goat anti-mouse IgG HRP conjugated secondary antibodies (Bio-Rad Laboratories). Immunodetection was performed with an enhanced chemiluminescence (ECL) detection kit (Bio-Rad Laboratories). The protein brands were analyzed using ChemiDoc system equipped with Image Lab software v. 4.1 (Bio-Rad Laboratories).

Briefly, cells (0.4 × 106) were homogenized in ice-cold lysis buffer. After centrifugation at 5,000 g for 30 min, the protein content of the supernatant was quantified using a Bradford protein assay. Samples were diluted, boiled with sample loading dye, and 100 µg were used in sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) (4561033EDU, Bio-Rad, USA). After blotting, membranes were blocked in 5% skim milk (70,166, Sigma-Aldrich) in tris-buffered saline containing 0.1% Tween-20 (P1379, Sigma-Aldrich). Membranes were incubated with Bcl-2 (1:1,000; ab59348, RRID: AB_289591, Abcam, UK), Bcl-xL (1:1,000; ab32370, RRID: AB_2847960, Abcam, UK), cytochrome c oxidase subunit IV (COX IV) (1:1,000; ab202554, RRID: AB_2847960, Abcam, UK), Bid (1:1,000; ab32060, RRID: AB_365478, Abcam, UK), cytochrome C (1:1,000; #11,940, RRID: AB_2637071, Cell signaling technology, USA), glyceraldehyde-3-phosphate dehydrogenase (GAPDH) (1:1,000; ab8245, RRID: AB_1267174, Abcam, UK) or beta-tubulin (1:1,000; ab179513, RRID: AB_1566837, Abcam, UK), and subsequently with secondary goat anti-rabbit horseradish peroxidase-conjugated antibody. Reaction products were visualized using an enhanced chemiluminescence detection kit (32106, Thermo Scientific, USA) and quantified by densitometry.

The following antibodies were ordered from Cell Signaling Technology (CST) and were used in a 1:1000 dilution: BCL-2 (D55G8, rabbit, #4223), MCL-1 (rabbit, #4572), BCL-XL (54H6, rabbit, #2764), BCL-W (31H4, rabbit, #2724), Bim (C34C5, rabbit, #2933), PARP (rabbit, #9542), BAX (rabbit, #2774), BAK (rabbit, #3814) and Puma (rabbit, #4976). The α-tubulin antibody (DM1A, mouse, #3873) was diluted 1:10000. Other antibodies used in a 1:1000 dilution: p21 (rabbit, ab109520, Abcam), p53 (D0-7, mouse, Neomarkers), Noxa (rabbit, ab140129, Abcam), Bid (rabbit, ab32060, Abcam) and MDM2 (N-20, rabbit, SC-813, Santa Cruz Biotechnology). Secondary antibodies used in a 1:10000 dilution: horseradish peroxidase (HRP)-conjugated goat anti-rabbit (NA9340V) and goat anti-mouse (NXA931) antibodies (GE Healthcare).

Mapping Poly(A) Sites in BID Gene

Check if the same lab product or an alternative is used in the 5 most similar protocols
We randomly selected 4 paraffin-embedded tissue sections for immunohistochemical analysis of BID expression in ESCC. The sections were incubated with primary antibody against BID (1:100, Abcam Cat# ab32060, RRID: AB_725689) at 4 C overnight and then detected with the ABC Kit (Pierce).
3 0 -Rapid-amplification of cDNA ends
We used 3 0 -Rapid-amplification of cDNA ends (3 0 -RACE) to determine the poly(A) sites (PAS) of BID with SMARTer RACE 5 0 /3 0 kit (TaKaRa). The sequences of gene-specific primers used for 3 0 -RACE are listed in Supplementary Table S2. The 3 0 -RACE products were then cloned and Sanger sequenced to accurately identify the BID PASs.

Mitochondrial Protein Isolation and Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
A Mitochondria/Cytosol Isolation Kit (BioVision, Inc., Milpitas, CA, USA) was used to separate cytoplasmic and mitochondrial proteins according to the manufacturer's instructions. According to our previous method [14] , the obtained proteins were quantified by the BCA (Thermo Fisher Scientific, Waltham, MA, USA) method. After denaturation, equal amounts of proteins (500 ng/µL, 10 µL) from different samples were separated by sodium dodecyl sulfate polyacrylamide gel electrophoresis and transferred to nitrocellulose membranes (Millipore). The blots were probed with the following antibodies: BID (ab32060; ABCAm, Cambridge, UK), truncated BID (tBID) (ab108293; ABCAm); cytochrome C (11940; Cell Signaling Technology, Danvers, MA, USA); cleaved caspase-3 (9654; Cell Signaling Technology); cleaved caspase-9 (7237; Cell Signaling Technology); and GAPDH (5174; Cell Signaling Technology). After washing, the membranes were incubated with a secondary antibody. Chemiluminescence (4200; Tanon Science & Technology, Shanghai, China) was used to detect the signals, and ImageJ 1.49v software (National Institutes of Health, Bethesda, MD, USA) was used for quantitative analysis of the signals.

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.
