BCL2 and malignant colon neoplasm: Our extensive qPCR results firmly support the conclusion that the Bcl2 gene is stably expressed at the mRNA level in human colon cancer cells regardless of the treatment with plant toxin gossypol, bacterial endotoxin LPS, or cottonseed-derived bioactive extracts, suggesting that Bcl2 gene expression is not regulated at the mRNA level but at the post-transcriptional level.
