Drug perks up old muscles and aging brains.

My TGF-b1 is sky high...is yours?

BERKELEY —
Whether you’re brainy, brawny or both, you may someday benefit from a drug found to rejuvenate aging brain and muscle tissue.

Researchers at UC Berkeley have discovered that a small-molecule drug simultaneously perks up old stem cells in the brains and muscles of mice, a finding that could lead to drug interventions for humans that would make aging tissues throughout the body act young again.

“We established that you can use a single small molecule to rescue essential function in not only aged brain tissue but aged muscle,” said co-author David Schaffer, director of the Berkeley Stem Cell Center and a professor of chemical and biomolecular engineering. “That is good news, because if every tissue had a different molecular mechanism for aging, we wouldn’t be able to have a single intervention that rescues the function of multiple tissues.”

The drug interferes with the activity of a growth factor, transforming growth factor beta 1 (TGF-beta1), that Schaffer’s UC Berkeley colleague Irina Conboy showed over the past 10 years depresses the ability of various types of stem cells to renew tissue.

“Based on our earlier papers, the TGF-beta1 pathway seemed to be one of the main culprits in multi-tissue aging,” said Conboy, an associate professor of bioengineering. “That one protein, when upregulated, ages multiple stem cells in distinct organs, such as the brain, pancreas, heart and muscle. This is really the first demonstration that we can find a drug that makes the key TGF-beta1 pathway, which is elevated by aging, behave younger, thereby rejuvenating multiple organ systems.”

Is that related to igf and gh? Sounds interesting. I think when it comes to these peptides , price plays a big part? Availability also.

TGF-B is one of the few cytokines that is pretty consistently raised in ME/CFS...
Several studies suggest aging is accelerated in ME/CFS as well.

Getting old explains a few things. Probably why antioxidants are used?? Also with aging comes increased oxidation. We are just rusting apart quicker than most.
