- 1Missing Y chromosome pieces found to drive cancer in men●Study shows how missing pieces of Y chromosome drive cancer in men
A new study shows how loss of parts of the Y chromosome, a common age-related change in men's cells, can promote cancer growth. Researchers report the missing pieces help tumours evade immune defences, offering a possible explanation for why some cancers in men are more aggressive and opening paths to new treatments.
- 2Physicists help explain how tumor DNA loops drive cancer▼Theoretical physics helps uncover the molecular mechanisms of extrachromosomal DNA in tumors
Researchers at the University of Naples Federico II report that theoretical physics methods have helped reveal the molecular mechanisms governing extrachromosomal DNA in tumors. These circular DNA fragments, separate from chromosomes, are known to promote cancer growth and drug resistance. The study applies physical modelling to understand their behavior, potentially opening new avenues for cancer research and treatment strategies.

Researchers report that biological features of prostate tumours can help determine which patients are most likely to benefit from hormone therapy. By profiling tumour biology, doctors may be able to better target treatment and avoid giving hormone therapy to those unlikely to respond, a step toward more personalised prostate cancer care.
