Aging is a complex process that affects multiple organs, and the discovery of a pharmacological approach to ameliorate aging is considered the Holy Grail of medicine. Here, we performed an N-ethyl-N-nitrosourea forward genetic screening in zebrafish and identified an accelerated aging mutant named (), harboring a mutation in the - () gene. Loss of leads to a short lifespan and age-related characteristics in the intestine of zebrafish embryos, such as cellular senescence, genomic instability, and epigenetic alteration.

Personalized cancer drug treatment is emerging as a frontier issue in modern medical research. Considering the genomic differences among cancer patients, determining the most effective drug treatment plan is a complex and crucial task. In response to these challenges, this study introduces the Adaptive Sparse Graph Contrastive Learning Network (ASGCL), an innovative approach to unraveling latent interactions in the complex context of cancer cell lines and drugs.

Introduction: The management of patients with Polycythemia Vera (PV) traditionally includes low-dose aspirin, phlebotomy, and cytoreductive therapy for high-risk individuals. Recent evidence suggests that cytoreductive treatment may be warranted for patients with additional risk factors beyond the traditional criteria of a history of thrombosis and age over 60 years. Introducing new therapeutic agents, including ropeginterferon alfa-2b and ruxolitinib, enables a more personalized treatment approach tailored to individual patient characteristics.

DNA-based nanomaterials have attracted increasing attention over the past decades due to their incomparable programmability and functionality. In particular, dendritic DNA nanostructures are ideal for constructing drug carriers due to their highly branched structure. In this study, an intelligent drug delivery system was constructed based on DNA dendrimers, in which the DNA duplexes were utilized for simultaneously loading both hydrophilic and hydrophobic small molecule drugs.
