Summary: This study analyzed the expression patterns of rice GRAS TF genes under abiotic and biotic stress conditions, identifying genes that were induced immediately after stress onset, especially in the roots of ABA-treated plants. OsGRAS39 was found to be highly expressed under sheath blight infection and abiotic stress treatments, with OsGRAS8, OsSHR1 and OsSLR1 also showing responsiveness. The research suggests that GRAS genes are potential candidate genes for enhancing stress tolerance in rice and other crop plants.

Summary: This study found DNA methylation alterations in the thalamus of sheep infected with scrapie, a form of transmissible spongiform encephalopathy. Hypomethylated regions were associated with genes involved in transmembrane transport and cell adhesion, while hypermethylated regions were related to genes involved in intracellular signal transduction. Furthermore, differentially expressed genes and genes highly expressed in specific types of CNS cells contained differentially methylated regions.

Summary: Vascular progenitor cells are activated to repair and form a neointima following various vascular damages. They not only play a role in resolving vascular lesions, but also contribute to neovascularization and angiogenesis associated with cancer. This review discusses the biology and pathophysiology of vascular progenitor cells, including their origins, stimuli, and activated pathways. It focuses on their involvement in tumor-induced vascular injury and their implications in promoting tumor angiogenesis during cancer proliferation and migration.

Summary: Approximately 30% of elderly adults with Alzheimer's disease neuropathology show no cognitive decline. This study investigated the genetic factors contributing to resilience to cognitive consequences of Alzheimer's disease neuropathology in a sex-specific manner. The results identified a female-specific resilience locus and highlighted numerous sex-specific molecular pathways related to resilience. These findings suggest the importance of personalized treatment based on sex and genetic factors.

Summary: In AD patients and mouse models, certain neurological features known as brain reserve may protect against AD-related cognitive decline. The genetic underpinnings of brain reserve and brain microstructure, which can be measured with dMRI, may advance AD treatment in diverse populations. By studying genetically diverse AD mice, we found that strain is the primary factor influencing brain microstructure and that memory is influenced by strain, sex, and 5XFAD genotype interactions.

Summary: The speed and scope of cognitive deterioration in Alzheimer's disease is closely associated with the advancement of tau neurofibrillary lesions across brain networks. Our study tested whether the rate of tau propagation is a heritable disease trait in mice, and found that 43% of the variability in tau spread was due to genetic variants segregating across different mouse strains. The identification of unique genetic variants that influence the progression of pathological tau may lead to the development of novel molecular targets to prevent or slow down tau spread and cognitive decline.

Summary: Through experiments on female mice, this study found that a high-fat diet can significantly shorten lifespan. Initial body weight and weight gain are important factors affecting longevity, while the response to a high-fat diet is modulated by gene-environment interactions. Classic serum metabolites may not be strong predictors of longevity.
