KSHV-driven tumor formation: how low-oxygen conditions push stem cells toward Kaposi’s sarcoma
Official title: Project 2: KSHV induces tumorigenesis by harnessing differentiation in hypoxia
Funded at University of Pennsylvania · NIH-11413534 · Data updated 2026-11-12
This project explores how low oxygen in tumors helps the Kaposi’s sarcoma virus hijack stem cells to form cancerous blood vessel–rich growths.

Who could benefit from this research
✓Could help
Patients with AIDS-associated Kaposi’s sarcoma or related conditions may benefit from future therapies informed by this research.
✕Less likely to help
Individuals without KS or AIDS-associated cancers may not directly benefit from these findings.
What this research studies
Kaposi’s sarcoma is linked to infection with a virus (KSHV) and abnormal blood vessel growth in low-oxygen environments. The team will study how hypoxia activates HIF, a key regulator that can drive both normal development and cancer progression, in KS-related cells. They propose that KSHV may use the hypoxia response to push mesenchymal stem cells toward an endothelial-like state, fueling tumor formation. By examining these cellular changes in endothelial cells and MSCs, the research aims to uncover a mechanism of viral tumorigenesis that could reveal new targets for therapy. The work combines cellular models and molecular analyses to connect hypoxia, viral biology, and KS pathology.
Why it matters
Potential benefit: Understanding this mechanism could identify new strategies to prevent KS progression or develop targeted therapies for AIDS-associated cancers.
How similar studies have gone: Previous work indicates hypoxia and viral factors influence KS biology, and this project builds on those findings with a novel focus on MEndT and differentiation.
