• Caspase 3/7 Link Autophagy to DNA Damage Responses

  2026-09-21

  The 2025 PLOS Biology study identifies CASP3 and CASP7 as active regulators of cytoprotective autophagy and DNA damage signaling during non-lethal stress in human breast cancer cells. Its genetic, molecular, and rescue experiments show that caspase-dependent PARP1 modulation may help stressed cells adapt, while loss of both caspases creates a synthetic-lethal interaction with BRCA1 loss.
