Terms Carcinogenic Phorbol ester and diacylglycerol (DA

What Types of Genetic Changes Are Involved In Generation Of The Cancerous State

Oncogenes Tumor suppressor genes

Retinoblastoma genes p53 genes

DNA repair genes

How Are Oncogenes Acquired Thay may be introduced by viral infec

tion Normal genes involved in control may

mutate and become oncogenic Oncogen and protooncogene

or genes

Oncogenicity May Include One or More of the Following

Signal transduction pathways leading to formation of active transcription factors may be inappropriately activated.

There may excessive amounts of particular transcription factors.

There may be abnormal transcription factors which are inappropriately active.

Oncogen Products As Components of Signalling Pathways

Normal receptor-not activated

Normal receptor-activated

Permanently active truncated EGF receptor

Normal receptor-pathway component permanently active

or genes

Tumour Suppressor Genes P53 genes

P53 protein: a transcription factor known to have several roles in cellular control

P53 p21 inactives the G1-specific Cdk activity

Apoptosis Retinoblastoma genes

Retinoblastoma protein blocks the cycle at the G1 checkpoint
