Defects in apoptotic programs contribute to a number of human diseases, ranging
from neurodegenerative disorders to malignancy, and treatment failure. The
genetic basis for apoptosis implies that cell death can be disrupted by
mutations, raising the intriguing possibility that cell numbers can be regulated
by factors that influence cell survival. It is well documented that the E2F1
transcription factor is a key regulator of apoptotic programs. E2F1-induced cell
death occurs via multiple pathways, some of which involve the tumour suppressor
p53, and autonomous of p53. This has led to the opinion that E2F1 functions as a
tumour surveillance factor, detecting aberrant proliferation and engaging
apoptotic pathways to protect the organism from developing tumours. Frequently,
novel players are discovered that expand the interpretation of apoptosis control
by E2F1. This information will help to produce new strategies to exploit
E2F1-induced apoptosis for therapeutic benefit.
