Key Points

To investigate the role of CRISPR-mediated MLH1 disruption in endometrial cancer growth and its effects on genomic instability and Wnt signaling.
Utilization of CRISPR technology to induce MLH1 disruption in endometrial cancer cells with MLH1 promoter methylation.
Assessment of microsatellite instability-high (MSI-H) status following MLH1 knockout (KD).
Evaluation of Wnt signaling pathway changes and cellular function in treated cells.
MLH1-KD leads to microsatellite instability (MSI-H) in cancer cells.
Genomic instability is enhanced following MLH1 disruption.
Wnt signaling pathway is significantly disrupted, correlating with impaired cellular functions and inhibited tumor growth.

Abstract

In EC cells with pre-existing MLH1 promoter methylation, MLH1-KD leads to MSI-H, enhances genomic instability, disrupts Wnt signaling, impairs cellular functions, and inhibits tumor growth, highlighting Wnt signaling and MSI-H as potential therapeutic targets in EC.
