How does the tumor microenvironment change as cancer progresses - & which cells appear, persist, or disappear along the way?

Excited to share our new study on the #TME answering this question!

Cancer cell and microenvironmental rewiring by ADAR1 loss impairs glioblastoma tumor growth and extends survival
Álvarez-Prado et al. report that targeting ADAR1 triggers cancer-cell-intrinsic anti-proliferative mechanisms and fosters anti-tumoral immune responses, blocking tumor growth and extending survival in preclinical mouse models of glioblastoma.

Glioblastoma (GBM) is the most common & aggressive brain tumor - with almost no progress for patients in decades

We asked - what if we could flip the switch on an immune pathway normally used to fight viruses, and turn it against GBM? 🦠🧠

By impairing ADAR1, a key RNA-sensing regulator, we uncovered a one-two punch:

- Cancer-cell intrinsic mechanisms slowed tumor proliferation in a PKR-dependent manner

- The immune microenvironment was reprogrammed into a pro-inflammatory, anti-tumoral state via type I IFN

🧐 Why does this matter?

GBM remains one of the deadliest cancers.

Targeting ADAR1 could simultaneously stop tumors from the inside - and mobilize the immune system from the outside.

These are questions that @alvarezprado.bsky.social is now pursuing in his new lab in Luxembourg
