A recent study identified SRSF1, an RNA-processing and splicing factor, as a molecule with geroprotective potential. Inducing SRSF1 expression rejuvenated human cells in vitro, extended lifespan, and significantly reduced frailty in mice [1]. Alternative approaches Differentiated cells have the capacity to rejuvenate if an appropriate molecular environment is provided. The best-known factors that enable cellular...

Cellular reprogramming is one of the technologies most associated with longevity. The field was created in 2006, when Shinya Yamanaka showed that a cocktail of four transcription factors, commonly known as OSKM, can cause de-differentiation and massive rejuvenation of a cell, creating an iPSC (induced pluripotent stem cell). About a decade later, partial reprogramming was...

In Advanced Science, a team of researchers has explained how partial cellular reprogramming through the OSKM factors restores nerve repair ability to older animals. Stress as a signal This paper focuses on Schwann cells, glial cells that are often responsible for maintaining the protective sheaths of myelin around neuronal axons and help peripheral nerves to...

In a recent study, researchers investigated aging- and disease-associated changes in gene expression related to epithelial-mesenchymal transition. Inducing the Yamanaka factors in mice allowed them to rejuvenate cells and tissues and reverse some of these aging-associated changes [1]. Rejuvenating cellular identity Aging-related epigenetic changes result in decreased capacity to maintain cellular identity [2], and some...

The authors of a recent study reported that OSKM/Yamanaka factor gene therapy in rats results in higher fertility at an older age compared to controls and allows older rats to have regular cycles [1]. Rejuvenating Yamanaka factors Yamanaka Factors - Opportunities for RejuvenationDrs. Takahashi and Yamanaka showed that they could use Oct4, Sox2, Klf4, and c-Myc...

Scientists have shown that long-term intermittent reprogramming limited to hippocampal neurons increases their fitness and improves cognitive function in a mouse model of Alzheimer’s disease [1]. Targeted in time and space Partial cellular reprogramming is one of the hottest directions in longevity research for a reason: it allows to rejuvenate cells without driving them all...
