Wrinkles Removed with RHAMM Protein, Study Shows

Said Turley, “Unlike neurotoxin agents, which have to be injected periodically, a localized injection of a RHAMM inhibitor should produce long-lasting skin volumizing effects and would not involve muscle paralysis, which means there would be no loss of expression if it were to be injected into the face.”

There are compounds now on the market that promote the production of adipocyte cells and result in increased subcutaneous fat, however, these adipocyte-promoting factors also increase the production of visceral fat. The mouse studies led by Bissell and Turley have shown that blocking RHAMM expression significantly increases subcutaneous fat while decreasing visceral fat. This suggests that blocking RHAMM should also have a beneficial effect on patients with obesity-related diseases, cardiovascular disease or diabetes.

Another unique advantage of RHAMM is that its expression in normal adult human tissues is restricted. “Therefore, anti-RHAMM agents should have low toxicity and according to preliminary animal studies, could be beneficial to patients with a tumor or inflammation-related disease,” said Turley.

Potential applications of RHAMM modulation in addition to wrinkle reduction include normalizing skin appearance after reconstructive or cosmetic surgery, such as grafted tissue on burn victims. It has also been shown to have a beneficial effect on tumors and inflammatory diseases in mice.
