E2F7
e2f7: A Transcription Factor at the Crossroads of Cell Growth and Death
Description
e2f7 is a member of the E2F family of transcription factors, which play a crucial role in regulating cell cycle progression, DNA replication, and apoptosis (programmed cell death). It is a key player in the G1/S phase transition, where it promotes the expression of genes required for DNA synthesis and cell division.
Associated Diseases
Dysregulation of e2f7 has been linked to several diseases, including:
- Retinoblastoma: A childhood eye cancer caused by mutations in the RB gene, which normally regulates e2f7 activity.
- Osteosarcoma: A bone cancer that may involve abnormal activation of e2f7.
- Breast cancer: Overexpression of e2f7 has been observed in some breast tumors, contributing to tumor growth and resistance to therapy.
- Lung cancer: Studies have suggested that e2f7 overexpression can promote lung cancer development and progression.
Did you Know ?
Approximately 6% of retinoblastomas are caused by mutations inactivating both copies of the RB gene, leading to unrestricted e2f7 activity.
