In vivo effects of CHOP protocol on onco and suppressor gene expression: follow-up study

In Vivo. 1998 Sep-Oct;12(5):489-94.

Abstract

In vivo investigation of onco/suppressor gene effects may provide new findings concerning chemical carcinogenesis. In earlier studies we pointed out the carcinogenic potential of COPP and ABVD chemotherapeutical protocols in "long-term" experiments. In another follow up study we proved the connection between the early gene expression changes and the late consequences of COPP and ABVD treatment during, a one year latency period. CHOP protocol is containing both proved carcinogenic cyclophosphamide and highly mutagenic doxorubicyn. CHOP protocol in "short-term" experiments shows strong effect on Ha-ras oncogene expression.
