Herpesviruses, which cause skin and genital infections, neonatal diseases, and meningitis, can successfully persist over a lifetime and transmit from one host to another. One key strategy that enables them to coexist within host cells is mimicry of cyclin-dependent kinases (CDKs)—proteins that regulate crucial cellular processes. A new study by researchers from Japan reveals novel insights into mechanisms underlying CDK mimicry by viral kinases, driven by phosphorylation of conserved amino acid residues.
Hematopoietic stem cells (HSCs) can differentiate into any blood cell. However, as HSCs age, they are more likely to differentiate into platelets and myeloid cells. This age-dependent shift is poorly understood due to a lack of marker genes. Now, scientists from the University of Tokyo present the Clusterin (Clu) gene as a novel biomarker of HSC aging. This allows easy identification of aged HSCs, shedding light on the biological mechanisms of aging.
An Osaka Metropolitan University researcher examined the nonlinear multidimensional factors that correlate with population changes according to city size. The results indicate that population changes correlated with welfare expenditures in small and medium-sized cities.
Nagoya University researchers in Japan have found that drug effectiveness, alcohol tolerance, and carbohydrate metabolism change with the seasons. Their findings are based on a comprehensive seasonal gene expression map, which investigated over 54,000 genes in 80 tissues in monkeys across one year. The study has implications for drug prescription and precision medicine.
Researchers in Japan have developed a predictive model that could improve treatment decisions for advanced pancreatic cancer patients. By combining tumor marker readings with patients' genetic information, their model predicts patient survival outcomes with greater accuracy and better identifies candidates who would benefit from surgery. The researchers found that specific genetic variations have a greater impact on tumor marker levels than the severity of the cancer.
It is expected that the new model will be used as an indicator to determine if surgery is a good option for patients receiving chemotherapy or radiation treatment. The study was published in the British Journal of Surgery.
