Western blot was performed as previously described (Lam et al., 2020 (link)). Specific primary antibodies [mouse monoclonal anti-human β-actin (Sigma-Aldrich); anti-PCNA, anti-PARP (Santa Cruz Biotechnology, Inc., Santa Cruz, California, United States of America); anti-PFKP, anti-LDHB, anti-Bcl-2, anti-survivin, anti-XIAP, anti-AKT, anti-CDK2, anti-CDK4, anti-CDK7, anti-Cyclin D2, H, anti-CDK4, anti-N-cadherin, anti-β-catenin (Cell Signaling Technology, Danvers, Massachusetts, United States of America); and corresponding horseradish peroxidase (HRP)-conjugated secondary (Cell Signaling Technology)] were purchased. An enhanced chemiluminescence (ECL) kit (GE Healthcare) was used to detect protein expression. Beta-actin was selected as a reference protein (Lam et al., 2020 (link)).

Protein was extracted using RIPA buffer (Sangon Biotech, Shanghai, People’s Republic of China) containing proteinase inhibitors (MedChem Express) and phosphatase inhibitors (MedChem Express). The protein concentration was measured using the Pierce BCA Protein Assay Kit (Thermo Scientific). The following antibodies were used for Western blot: anti-CDK7 (Cell Signaling Technology, Danvers, MA, USA), anti-α-tubulin (Cell Signaling Technology), anti-poly(ADP-ribose) polymerase (anti-PARP) (Cell Signaling Technology), anti-cleaved PARP (Cell Signaling Technology), anti-RNA Pol II (Abcam, Cambridge, UK), anti-phospho RNA Pol II (Ser2) (Abcam), anti-phospho RNA Pol II (Ser5) (Abcam), anti-phospho RNA Pol II (Ser7) (Millipore), anti-CDK1 (Abcam), and anti-CDK1 (phospho T161) (Abcam).

Immunoblotting to detect protein detection was performed using SDS-PAGE as previously described (Lal et al., 2014 (link)). Membranes for immunoblotting were probed with antibodies against anti-phospho-CTD-RNAPII-S2 (04-1571; Millipore), anti-phospho-CTD-RNAPII-S5 (04-1572; Millipore), anti-CDK7 (2916; Cell Signaling Technology), anti-CDK13 (A301-458A; Bethyl), anti-cleaved poly(ADP ribose) polymerase (Asp214; 9541; Cell Signaling Technology), anti-cleaved caspase 3 (Asp175; 9664; Cell Signaling Technology), NRF2 (12721; Cell Signaling Technology), and anti-α-tubulin (Sigma-Aldrich). Chemiluminescent (32106; Thermo Fisher Scientific) signal was captured using a Syngene G-BOX iChemi XT imager.

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.
