Keap1 Cancer Research Results

Keap1, Kelch-like ECH-associated protein 1: Click to Expand ⟱
Source:
Type:
Kelch-like ECH-associated protein 1 (Keap1) is a key regulator of the transcription factor Nrf2.

-In several tumor types, loss of Keap1 function (either due to gene mutations or low protein expression) results in unrestrained Nrf2 activity.
• Persistent Nrf2 activation is thought to:
 - Provide tumor cells with enhanced protection against oxidative stress.
 - Contribute to chemoresistance and radioresistance.
 - Promote metabolic reprogramming that fuels tumor growth.

• Thus, in many cancers, altered Keap1 status can serve as an indicator of poor prognosis and has been investigated as a potential target for therapeutic intervention.
