Research Roundup

AngiogenesisStem Cell Signals Encourage Blood Vessel Formation in Mice: Researchers publishing in Aging have outlined how biochemical signals derived from created stem cells encourage blood vessels to form new branches in naturally aged mice.

Taurine Increases Median Lifespan in Mice by 12%: In a new study published in Science, taurine supplementation led to a significant lifespan extension in mice and health benefits in non-human primates.


MicrobesMicrobial Composition May Affect Lifespan: New research published in Scientific Reports suggests that microbes in the human gut and mouth can impact how long people live. Bacteria and other microbes are often associated with diseases, but disease-causing microbes are only a minority. The majority of microbes are harmless or beneficial to humans.

Creatine on the Brain: A Review: A review recently published in Sports Medicine has discussed a considerable number of research papers that describe the effects of the muscle-building supplement creatine on the brain.

CnidarianCellular Senescence Drives Regeneration in Cnidarians: Scientists have demonstrated that full-body regeneration in cnidarians, a group of animals that includes the jellyfish and hydra, can be driven by signals from senescent cells. This might be the original purpose of cellular senescence.

The Longevity Factor Klotho Improves Memory in Monkeys: Researchers have explained in Nature Aging how klotho, a factor associated with longevity, improves the cognitive abilities of rhesus macaques. Klotho had previously been found to improve cognitive function in mice.

Disagreeing clocksUsing Proteins and RNA to Determine How Old You Are: A paper published in Aging goes into detail about the proteins and RNA pieces that increase and decrease with aging, suggesting a multiple-clock approach to biomarkers.

Better Health in Older Adults, One Step at a Time: Research published in Experimental Gerontology suggests that even smaller amounts of daily physical activity can benefit people over 60.

KillifishSenolytics Restore Regeneration in Killifish: Researchers publishing in npj regenerative medicine have found that destroying senescent cells through a well-known senolytic combination gives older killifish back some of their regenerative abilities.

Aerobic, Resistance Training Differently Affect Skin Aging: According to a study published in Nature Scientific Reports, while both aerobic and resistance exercise improve some aspects of skin aging, only the latter is able to increase skin thickness.

SortingMaking Genetically Engineered Stem Cells Viable: Researchers publishing in Cell Stem Cell have announced a new method of accurately and rapidly cloning genetically engineered stem cells. While the accuracy of genetic modification through the well-known CRISPR/Cas9 system continues to improve, the technology remains imperfect.

Rejuvenating Cells Using A New Small Molecule Approach: A team led by renowned Harvard geroscientists David Sinclair and Vadim Gladyshev has reported successful chemically induced partial cellular reprogramming in vitro. The researchers have also developed a novel cellular rejuvenation assay.

DNAFinding The Genes for Longevity in Mammals: Researchers have analyzed the activity of genes in the livers, kidneys, and brains of over a hundred mammals and found genes that are consistently associated with longevity. Between the shortest-living and the longest-living mammal, there is a more than 100-fold difference in lifespan.

Repairing the Long-Term Damage of Smoking: Researchers publishing in Aging Cell have described how treating the increased senescent cell burden that comes with cigarette smoke exposure can repair some of the damage.

Variety of clocksNew System-Specific Epigenetic Clocks Revealed: A group of researchers led by Morgan Levine of Altos Labs has created a set of methylation clocks that can detect various aging patterns.

Metformin Protects Against Muscle Atrophy in Clinical Trial: Researchers publishing in Aging Cell have documented a human clinical trial showing that metformin reduces atrophy caused by long periods of bed rest. Long periods of disuse cause muscles to atrophy and accelerate the age-related muscle wasting known as sarcopenia.

Review Links Statins to Insulin Resistance and Diabetes: A systematic review lends support to the idea that statins, which are life-saving, cholesterol-lowering drugs, are associated with an increased risk of insulin resistance and type 2 diabetes.

Vigorous Weekend Exercise May Be Enough: A study suggests that “weekend warriors”, people who only exercise for one or two days a week, enjoy similar cardiovascular benefits as those who exercise more regularly.
