Scientists map proteins that let carcinomas change identity

Researchers at Cold Spring Harbor Laboratory have identified key proteins and protein complexes that help certain carcinomas shift their cellular identity and potentially evade treatment. Two new studies, focusing on pancreatic cancer and tuft cell lung cancer, highlight molecular structures that could become targets for more precise and selective therapies.
A study shows that advanced lung cancer patients receiving immunochemotherapy earlier in the day survive longer. A Hong Kong medical expert says the discovery opens possibilities for optimal treatment times, though more research is needed. The research was led by academics from Hunan Cancer Hospital in mainland China and supported by the Chinese University of Hong Kong’s faculty of medicine.

Researchers in Japan have uncovered how cancer cells use tiny vesicles to spread the immune-suppressing protein PD-L1, explaining why immunotherapy often fails. A protein called UBL3 directs this process, but common statins can disrupt it, potentially boosting treatment effectiveness. The findings, from patient samples and lab tests, suggest a simple way to improve outcomes for lung cancer patients.
Researchers have identified a novel protein biomarker that detects lung cancer at an early stage with high accuracy. The discovery, detailed in a recent study, could enhance screening methods and improve patient outcomes. Clinical trials showed promising results in identifying the disease before symptoms appear.
