I understand that transcriptional factors affect the transcription of target genes and decide which protein to make and when. Whereas growth factors like oestrogen affect the RATE of transcription and cell division. Do proto-oncogenes produce these growth factors? I think that transcriptional factors operate using the second messenger model but do growth hormones use this mechanism too when they are produced by the proto-oncogenes to stimulate cell division? Any help would be greatly appreciated, I'm really confused :s Many thanks Salman
