G enes I nvolved with Carcinogenesis What’s the function of these genes in normal and cancer cells? Casey, Abrar , Sally, Alief , Jess. Proto-oncogenes: genes that encourage the growth of a cell.
“A mutation can turn one of these genes into a cancerous oncogene that drives excessive cell division. Oncogenes can encode signalling molecules such as growth factors, or components of the signalling cascades that regulate the mediate the cellular responses to such signalling molecules.”
