GSK3α and GSK3β mRNA and proteins are overexpressed in lymphomas. (A) Real-time PCR quantitation showing that GSK3α and GSK3β mRNAs are overexpressed in lymphoma lines in comparison with low expression in normal B or T lymphocytes. (B) Western blot images demonstrating that GSK3α and GSK3β proteins are also abundantly expressed in various lymphoma lines in comparison with purified normal B or T lymphocytes.
