Scientists reverse aging in skeletal muscle for the first time. Largest Breakthrough in longevity

Reversing aging

Scientists in University of Buffalo studying aging muscles cells, have discovered how to reverse aging in skeletal muscl for the first time; they noted that aging in muscle cells is a function of a cell itself that are not being able to divide and repair itself.  Cellular senescence as the process is known as happens during aging. The aging study found that by the overexpression of a particular protein called NANOG, the cell does not have to be reset to a different state to reverse aging. This is one of the larget breakthrough in productivity.

The previous attempts to reverse aging using genome mapping of jellyfish (known for its ability to rebirth itself) in cells have been focused on returning the cell to a more stem-cell like state. This literally resets the cell to it formation process. This new technique takes an entirely different path.

Cellular senescence happens during aging, when cells reach a point when they are no longer able to repair themselves and can’t divide. The genetic material within the cell becomes unstable causing the cell to degenerate and become diseased. As a consequence, our entire body ceases to regenerate cells over time. This study shows how this is somewhat misleading and not as bad as it sounds.

In the embryonic precursor to muscle cells, senescent human myoblasts, a protein known as NANOG is found. By overexpressing, or exciting the NANOG protein, scientists were able to reverse age related degradation of the cell and increase their own DNA repair mechanisms.

In more interesting it was shown when NANOG was overexpressed in prematurely aging mice, the number of muscle stem-cells increased, further reenforcing the results of the lab study on human myoblasts, that NANOG might have rejuvenating properties. That could help in reversing the aging process.

“Our work focuses on understanding the mechanisms of NANOG’s actions in hopes of discovering druggable targets in signaling or metabolic networks that mimic the anti-aging effects of NANOG,” says the study’s corresponding author Professor Stelios T. Andreadis in a statement

The study had gone on to say, that Skeletal muscle is a highly regenerative organ that comprises about 45% of the total body mass and enable skeletal movements as well as regulate metabolism.

The act of regeneration, repair, or new growth in the body, is done in the muscle tissue by the proliferation of myofibers. Myogenic progenitors, or the basic starters of muscle growth, when activated, proliferate, differentiate and contribute to the regenerative growth of damaged myofibers.

The decline in myogenic progenitors, or those little starter forces in the myofibers, decrease in number and regenerative capacity over time. The study at the University of Buffalo has shown how a protein in myogenic progenitors, NANOG, is overexpressed, or excited, the process increases the number and regenerative properties of the myogenic progenitors. A process of rejuvenation of the entire process.

Drawbacks on this research.

One of the challenges is that the NANOG did not proliferate indefinitely, when the cumulative cell numbers plateaued after about 20 or 25 days of overexpression. This drawback is not the end of the research to find a way to reverse aging, but instead a reason to continue on in discovery of further ways to defeat the aging process.

In the pursuit to halt and reverse the aging process, various strides have been made in the last. Just last month, a study showed that a supplement could reverse the hallmarks of old age and promote healthier aging and ultimately healthy living.

The latest discovery was published in the journal Science.
