“What makes being a scientist exciting is that I don’t know what I’m going to find tomorrow,” says Akhila Rajan, Ph.D., an assistant professor in the basic sciences division at Fred Hutchinson Cancer Research Center in Seattle, Washington. Dr. Rajan is supported by an NIGMS early stage investigator Maximizing Investigators’ Research Award. These awards provide stable and flexible funding for a program of research that falls within NIGMS’ mission. Check out the highlights of our interview with Dr. Rajan to learn about her research and journey as ...

In conclusion, mitophagy pathways play an important role in maintaining physiological homeostasis, are involved in the mechanisms of aging and neurodegenerative disorders, and represent promising targets for the development of potential therapeutic agents aimed at regulating mitochondria quality control in neurons and glial cells. A significant number of molecules that induce or inhibit mitophagy are currently under consideration, which may be useful for testing hypotheses or developing drugs for the treatment of neurodegenerative diseases. The validation of promising drugs in animal and cell models, including neurons and ...

A son ’s brain cancer. A father’s story. PODCAST
“As you wait, you have a lot of time to think. You comb through the past in search of something you might have missed. If we had acted sooner on the signs of his illness —had the cancer been diagnosed earlier—would Lee have had a better chance?

In this study, we therefore analysed the influence of lithium treatment on lifespan and parameters of health during ageing in mice.
To determine the concentration of lithium suitable to be administered in a longitudinal ageing study, we first tested the effects of lithium chloride (LiCl) in doses from 0.01 to 2.79 g LiCl per kg chow. C57Bl/6J mice fed with 1.05-2.79 g/kg LiCL in the diet showed lithium plasma levels between 0.4 and 0.8 mM/l. While plasma levels to 0.4 and 0.8 mM/l are well tolerated by human patients, at doses above 1.44 g LiCl/kg, we observed an obvious dose-dependent polydipsia combined with a dis...

The Early Years of Mitochondrial Transplantation as a Therapeutic Strategy
Mitochondria are the power plants of the cell, generating the chemical energy store molecule adenosine triphosphate (ATP). Throughout the body, mitochondrial function declines with age, leading to corresponding declines in tissue and organ function. This universal malaise appears to be a downstream consequence of the underlying causes of aging. Those causes in some way lead to changes in gene expression that alter mitochondrial dynamics in ways that reduce the efficacy of the quality control mechanism of mitophagy. When not regularly destroyed, worn and dysfunctional mitochondria accumulate, and ATP production suffers.

In conclusion, this study examined how age and the process of aging are associated with changes in the microbiome of the small intestine, using validated sampling and processing techniques. The most significant differences are higher relative abundance of the phylum Proteobacteria and decreased relative abundance of Bacteroidetes in older subjects when compared to the youngest group. The higher relative abundance of Proteobacteria appeared to affect other duodenal microbial taxa, leading to decreased microbial diversity and increased relative abundance of coliforms and of anaerobic bacteria. The small intestine is vital to...

In conclusion, premature thymic involution and chronic inflammation greatly contribute to increased morbidity and mortality in CKD patients. Mechanisms are likely to be multiple and interlinked. Even when the quest to fountain of youth is a pipe dream, there are many scientific opportunities to prevent or to, at least in part, reverse CKD-related immune senescence. Further studies should precisely define most important pathways driving premature immune ageing in CKD patients and best therapeutic options to control them.

Cellular Reprogramming, and the Goal of Separating Dedifferentiation from Epigenetic Rejuvenation
Rejuvenation takes place very early in embryonic development. The germline cells that go into the creation of an embryo are well protected and maintained in comparison to the average somatic cell in the adult body. Nonetheless, there is an accumulation of age-related epigenetic changes and molecular damage. Cells purge themselves of as much of this change and damage as possible, in order to ensure that the young are born with young somatic cells and tissues. This is primarily a resetting of epigenetic controls over gene expression, decorations on the structure of the genome that control shape and access to specific genes b...

In conclusion, patients over 90 years of age had an overall low prevalence of fractures and relative preservation of bone health, suggesting a preserved bone molecular profile in these individuals. Epigenetic factors and activity levels might also have favorably affected bone health. The low percentage of osteoporosis and fractures likely reduced the morbidity and mortality in this population, potentially contributing to their overall longevity.

Fecal Microbiota Transplant as a Treatment for Neurodegenerative Conditions
It is thought that an appreciable fraction of the chronic inflammation of aging is caused by changes in the gut microbiome. There is a bidirectional interaction between the immune system and the microbial populations of the intestinal tract. The immune system gardens these populations, destroying problematic microbes. Microbes secrete metabolites and other molecules that can either benefit or harm the function of the immune system, the harms caused particularly by those microbes capable of provoking a sustained inflammatory response. The immune system declines with age for a range of reasons, and reduced efficacy in immune...

4 Reasons to Support Sustainability
When President Biden entered office, he enhanced the national sustainability standards. As we develop an eco-friendly infrastructure, we adopt new technologies and systems that reduce greenhouse gas emissions. Society may accept the alterations without understanding the expansive benefits.
By exploring sustainability’s advantages, individuals are more likely to support the transition away from fossil fuels. Utilizing electric appliances, adopting an eco-friendly diet, eliminating fast fashion purchases and more can shrink one’s carbon footprint while enhancing savings. Over time, sustainable commercial and individua...
