SEOUL, South Korea (Reuters) - South Korean researchers have developed candidate hair loss products,
The Ministry of Science and Technology announced yesterday that a professor at Yonsei University's Department of Biotechnology and Bioengineering discovered a candidate protein that inhibits the function of hair protein.
The researchers noted that the amount of protein called 'CXXC5' is high in the scalp tissue of a person who has hair loss.
This protein is a key component of the intracellular signaling pathway (Wnt signaling pathway) that plays a role in hair formation and wound healing.
To better understand the function of the protein, the researchers studied human hair follicle cells, confirming that this protein binds to other proteins and inhibits hair growth.
This suggests that if the binding of the two proteins is blocked, hair can be properly formed.
The researchers actually produced a biochemical (protein fragment) 'PTD-DBM' that blocked the binding of the two proteins and confirmed its efficacy in mice.
Applying PTD-DBM for 28 days to the hairless area, the hair follicles will be healthy and the hair will come back.
If you apply VPA (valproic acid), a chemical that activates the winter signaling system, the hair growth effect is higher.
Existing hair loss treatments use the principle of promoting the growth rate of hair, so it is not effective when hair loss has already progressed. In addition, there were side effects because of the simultaneous use of drugs that inhibit male hormones.
The researchers said the candidate for hair loss treatment has the potential to solve all of these problems.
The researchers are now testing animals for toxicity to this candidate drug.
Professor Choi Kang-yeol said, "We have developed a novel material that regulates the function of hair proteins and controls the function of hair to regenerate hair." I hope to contribute, "he said.
The research was supported by the Ministry of Education, Culture, Sports, Science and Technology (MOCIE), and the research results were published in the Journal of Investigative Dermatology on the 20th of last month.
