Researchers have found that the sirtuin SIRT1 stabilizes the human genome by suppressing retrotransposition, which occurs when parts of the genome transcribe themselves onto other parts. When DNA modifies itself Long interspersed elements-1 (LINE-1) have existed in organisms' genomes, including our own, for well over a billion years [1]. They are the only autonomous elements...

In Aging Cell, researchers have explained how the sirtuin SIRT6 protects against proteostasis-related brain disorders by maintaining the function of nucleoli and limiting protein production. The nucleus and nucleoli Loss of ProteostasisThe loss of proteostasis is the failure of the protein-building machinery of the cell and the accumulation of misfolded proteins, which is one of...

Researchers publishing in Physical Review X have discovered compounds that can double the efficiency of the sirtuin SIRT3 in processing NAD+. Looking for a new way to boost enzymes The researchers begin their paper by noting that most drugs administered to people are geared towards inhibition of particular enzymes in order to treat a disease....

A new review authored by three acclaimed geroscientists paints a promising picture of past and ongoing human clinical trials of prospective anti-aging drugs [1]. From worms and mice to humans The biology of aging is an exciting new field, but most of its successes have been in animal models, from the early breakthroughs in yeast...

Working with non-human primates, scientists have discovered that the protein SIRT2, a member of the sirtuin family, might play an important role in slowing cardiac aging [1]. The heart of the matter The heart is arguably the hardest worker among the organs, constantly pumping enormous amounts of blood without ever skipping a beat (well, almost)....

Researchers publishing in Aging have outlined a relationship between disc degeneration, macrophage polarization, inflammation, and sirtuins, demonstrating their effectiveness in a rat model of the disease. A crippling and painful disease Intervertebral disc degeneration (IDD) is a major cause of pain and disability [1], as it leads to the physical deterioration of the shock-absorbing discs...
