Improving cancer treatment by targeting a specific protein to overcome drug resistance

Targeting p300 to Overcome PARP inhibitor resistance induced by acidic tumor microenvironment

NIH-funded research University of Tx Md Anderson Can Ctr · NIH-10931368

This study is looking at a new way to make ovarian cancer treatments work better for patients with BRCA1/2 mutations by combining two types of medicines to help overcome challenges caused by the tumor's environment.

What this research studies

This research aims to enhance the effectiveness of PARP inhibitors, which are used to treat certain types of ovarian cancer, particularly in patients with BRCA1/2 mutations. The focus is on overcoming resistance caused by the acidic environment of tumors by targeting an epigenetic regulator known as p300. The study will utilize a combination of a p300 inhibitor and PARP inhibitors to determine if this approach can improve treatment outcomes. Patients may benefit from a novel therapeutic strategy that addresses a significant challenge in cancer treatment.

Who could benefit from this research

Good fit: Ideal candidates for this research are ovarian cancer patients with BRCA1/2 mutations who are experiencing resistance to PARP inhibitors.

Not a fit: Patients without BRCA1/2 mutations or those not affected by PARP inhibitor resistance may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could lead to improved treatment options for ovarian cancer patients who currently face resistance to existing therapies.

How similar studies have performed: Previous research has shown promise in targeting similar pathways to overcome drug resistance in cancer treatment, indicating potential for success in this novel approach.
