Summary: “Calorie restriction (CR) is the only nutritional strategy proven to extend lifespan, prevent age-related diseases, and delay functional decline. The effects of CR when started early in life are not well understood. This study found that young female rats treated with CR showed similar expression patterns of key genes/pathways associated with healthy aging compared to old animals treated with CR, while in male rats these effects were reduced.”

Summary: Vascular endothelial function declines with age, but there is variability in this decline across individuals. Frailty index can be used as a surrogate for biological age, and this study found that frailty is related to age-related decline in vascular function, but the relationship is dependent on sex and the artery examined. Arterial oxidative stress and proinflammatory signaling may mediate the relationship between frailty and endothelial function.

Summary: Sex differences in trajectories of global sulcal morphology were observed, with females having thicker cortex until age 40 and converging trajectories thereafter. Sulcal shortening was faster before age 40, while sulcal shallowing and widening were faster afterwards. Males showed greater variability in cortex volume and lower variability in sulcal width.

Summary: Lipids are important for brain structure and function, and studies show that men experience greater brain atrophy than women with aging. This study investigated the sex-specific associations between circulating lipids and brain atrophy in a sample of cognitively normal older adults. Results revealed sex differences in the associations between specific lipid profiles and accelerated brain aging. The findings suggest the need for further investigation into the mechanisms underlying these sex-specific lipid profiles.

Summary: Biological sex plays an important role in many diseases, with distinct differences between men and women in disease development. Cellular senescence may underlie these sex differences and could be a driver of sex-specific disease outcomes. Further research is needed to investigate sex differences in cellular senescence and validate findings from animal studies in human contexts.

Summary: Mitochondrial uncoupling proteins (UCP) 1-3 have multiple physiological functions, and most studies suggest that they play a role in preventing oxidative stress. The exact mechanism is still unclear, but it may involve proton return to the matrix and other functions such as Ca2+ transport.

Summary: Colorectal cancer (CRC) is a highly diagnosed cancer with significant mortality rates, and early detection is crucial for improving patient survival. Current CRC screening programs involve stool tests and colonoscopies, but the use of new biomarkers could enhance screening effectiveness. Omics technologies offer promise in detecting novel biomarkers for CRC across different sample types.

Summary: Metastasis is a crucial factor in the mortality of colorectal cancer (CRC) patients. This study explores the changes in mitochondrial function associated with the metastatic stage of CRC and investigates whether they could be utilized as therapeutic targets. The findings indicate notable differences in mitochondrial functionality between tumor tissue and normal adjacent tissue in metastatic CRC patients. These alterations contribute to the promotion and maintenance of the metastatic phenotype, highlighting the impairment of mitochondrial function in tumor tissue during the metastatic stage.

Summary: Non-tumor adjacent tissue has an important role in the development and inflammatory process of colorectal cancer. This study analyzed the expression of inflammatory, epithelial-mesenchymal transition (EMT), and metastasis-related proteins in tumor and non-tumor adjacent tissues from colorectal cancer patients. The results showed that tumor tissue had increased levels of metastasis and EMT-related proteins compared to non-tumor adjacent tissue, particularly in stage II. Tumor tissue from stage II also had increased levels of inflammatory-related proteins, which was also observed in non-tumor adjacent tissue from stage II. Additionally, higher expression levels of Vimentin and VEGF-B were associated with lower relapse-free survival in stage II patients. These findings suggest that these proteins could be potential biomarkers for early diagnosis of colorectal cancer.

Summary: This study analyzed the effect of oxaliplatin on tumor spheres formation efficiency, cell viability, cancer stem cells, and inflammation in primary- and metastatic-derived colorectal tumor spheres. The results showed that primary-derived spheres responded to oxaliplatin by modulating cancer stem cells and stemness properties, while metastatic-derived spheres exhibited an inflammatory response. In addition, the expression of inflammatory markers after oxaliplatin treatment correlated with poor prognosis and a metastatic phenotype. These findings highlight the importance of drug testing and personalized medicine in early-stage colorectal cancer.

Summary: Colorectal cancer is the third most common cancer worldwide, and the lack of early and specific biomarkers leads to late-stage detection. Tumors release extracellular vesicles (EVs) that have various functions and can be used as a source of biomarkers. Bowel lavage fluid (BLF) obtained during colonoscopy is an underutilized sample that represents EVs from tumor cells and has the potential to be a useful research tool. In this study, EVs from BLF were isolated and characterized, confirming their suitability for CRC study and potential as biomarkers for diagnosis and monitoring.

Summary: In mammals, the integrated requirements of all activities must conform to a sustained rate of metabolism for the pup's development and adult life. Partitioning available energy according to short-term priorities allows animals to optimize long-term reproductive success. In this study, the development of thermogenic capacity in altricial rodent pups, specifically Ctenomys talarum, was evaluated. The results showed that non-shivering thermogenesis was absent in the pups until day 60, despite the presence of molecular markers for thermogenesis in brown adipose tissue deposits. However, the total thermogenic capacity became fixed at an early age, indicating an improvement in shivering thermogenesis efficiency after day 10.
