Using O'PROTAC degraders to target the KSHV LANA protein

Development of O’PROTACs-based degraders targeting an oncogenic viral protein

NIH-funded research Univ of Arkansas for Med Scis · NIH-11232369

Researchers are making small molecules called O'PROTACs that can destroy a viral protein (LANA) that helps KSHV-linked cancers grow, with the goal of helping people with KSHV-associated Kaposi’s sarcoma or primary effusion lymphoma.

What this research studies

If you have Kaposi’s sarcoma (KS) or primary effusion lymphoma (PEL), this project is working on a new kind of drug that aims to remove a viral protein the cancers need to survive. Scientists will design O'PROTAC degraders that bind the KSHV-encoded LANA protein and trigger its destruction. They will test these molecules in lab-grown KSHV-positive tumor cells and in animal models to see if the tumors shrink or stop growing. Results could guide future human therapies for immunocompromised patients with KSHV-driven tumors.

Who could benefit from this research

Good fit: People diagnosed with KSHV-associated Kaposi’s sarcoma or primary effusion lymphoma, especially those who are immunocompromised or living with HIV, would be the most relevant patient group.

Not a fit: Because this is early-stage laboratory and animal research, people without KSHV-related cancers or those needing immediate clinical treatment should not expect direct personal benefit now.

Why it matters

Potential benefit: If successful, this work could lead to new treatments that shrink or block the growth of KSHV-driven tumors in immunocompromised patients.

How similar studies have performed: PROTAC-style protein degraders have shown promise in preclinical cancer studies, but applying O'PROTACs specifically to degrade the KSHV LANA oncoprotein is a novel and largely untested approach.
