Expression of Bcl-2 family members other than Mcl-1 are unaffected by Mcl-1 AS treatment.

Protein samples from untreated and PMA- and oligodeoxynucleotide-treated U937 cells were analyzed by Western blotting for various Bcl-2–related proteins. Ponceau-stained actin is shown to demonstrate the equivalence of loading. The results are representative of 3 separate experiments.
