A recent review highlights that post-translational modifications add a dynamic regulatory layer to KRAS beyond canonical GDP/GTP cycling, controlling membrane localization and trafficking, nucleotide exchange, effector engagement, protein stability, and degradation. Targeting PTM enzymes and modification-dependent regulatory networks may provide new therapeutic opportunities and strategies to overcome resistance in KRAS-driven cancers.
Head and neck squamous cell carcinoma (HNSCC) is an aggressive malignancy characterized by poor survival due to rapid progression, metastasis, and cisplatin resistance. The chaperonin containing TCP-1 subunit 2 (CCT2), a subunit of the chaperonin-containing TCP-1 (CCT) complex, has been previously implicated in several cancers, but its specific role and contribution to chemoresistance in HNSCC remain elusive.
Extracellular vesicles (EVs) are tiny particles secreted by cells that mediate intercellular communication and regulate immune responses. By carrying microRNAs, proteins, and lipids, EVs spread cellular senescence and promote the senescence-associated secretory phenotype (SASP), creating a cycle of "senescence-inflammation-dysfunction". In a recent review, researchers from China elaborate how EVs mediate cellular senescence in multiple chronic lung diseases. It also discusses the advances, existing challenges, and translational prospects of EV-based therapies for these aging-related pulmonary diseases.
New research to be presented at the Annual Meeting of The European Association for the Study of Diabetes (EASD) in Milan, Italy (Sept 28 – Oct 2) shows no link between semaglutide use and pancreatic cancer using nationwide registry data from Denmark, Sweden and Norway. This regulator-mandated post authorisation study, funded by Novo, the manufacturer of semaglutide, is presented by Professor Anton Pottegård, University of Southern Denmark, Odense, Denmark, and colleagues.
