Jurkat cells (2 × 106) were transfected in Nucleofector solution (Nucleofector Kit V, program X-01; Amaxa Biosystems) with 2 μM of nonsense siRNA (Qiagen), Bid siRNA (Qiagen) or Bim siRNA (Qiagen) using the Nucleofector apparatus. MT-2 cells were transfected in Nucleofector solution (Nucleofector Kit V, program O-17; Amaxa Biosystems) with 2 μM of nonsense siRNA (Qiagen) or HIF-1α siRNA (Qiagen). Seventy-two hours after transfection, cells were collected for protein expression analysis and different treatments as indicated in the figure legends.
