What this research studies

This project uses genetically engineered mouse models, laboratory cell models, and human tumor datasets to understand how a stress-activated kinase pathway (SAPK/AP-1) controls small cell lung cancer. Investigators will create mice lacking Map2k4 or Map2k7 together with Rb/p53 deletions to see whether loss of this pathway speeds tumor formation. They will combine cell-based functional screens with analysis of human tumor sequencing and expression data to link the SAPK/AP-1 axis to the ASCL1-driven (SCLC-A) subtype. The goal is to reveal molecular weaknesses that could point toward future targeted therapies.

Who could benefit from this research

Good fit: Ideal participants are people with a diagnosis of small cell lung cancer, particularly tumors of the ASCL1-driven (SCLC-A) subtype, or patients willing to contribute tumor samples or data for research.

Not a fit: People without small cell lung cancer or whose tumors do not involve the ASCL1/SAPK pathways are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, this work could identify new molecular targets that lead to targeted treatments for people with small cell lung cancer.

How similar studies have performed: Preliminary lab and sequencing work supports a role for the SAPK/AP-1 pathway in SCLC and mouse data show tumor acceleration when Map2k7 is deleted, but similar findings have not yet produced approved patient therapies.
