Fig 5. Resveratrol (RV) and peanut stem extract (PSE) enhance irradiation (IR)-induces double-strand breaks (DSBs) in radioresistant prostate cancer cells.

Protein expression levels of target molecules in LAPC4-KD cells that were untreated (mock), exposed to IR (2Gy) alone, or in combination with RV or PSE (25 or 500 μg/mL, respectively). Representative western blot results from one of three independent experiments are shown. β-actin was the loading control. Expression level of each protein was quantified using signal intensity and indicated below each lane.
