Effects of QR-KLU on the apoptosis and cell cycle of liver cancer cells (n = 6). (A) Effects of QR, KLU, and QR-KLU on the apoptosis of Hepa1–6 cells under normoxic and hypoxic conditions. Hypoxic condition was created by adding 100 µM cobalt dichloride. (B) Effects of QR, KLU, and QR-KLU on the cell cycle of Hepa1–6 cells. QR-KLU peptide (QR)–drug (KLU) conjugate.
