Quantitative reverse transcription-polymerase chain reaction (qRT-PCR) According to the protocol, total RNA was extracted from the large intestine with TRIzol (Life Technologies Japan Ltd., Tokyo, Japan) using a Dounce Tissue Grinder (DWK Life Sciences, LLC, NJ, USA), and 500 ng of RNA was reverse transcribed to complementary DNA using the Super Script III First-Strand Synthesis Super MIX kit (Life Technologies Japan Ltd.)
During the application period, the peptide stimulates gene expression related to collagen production, elastin synthesis, and growth factor secretion, creating a regenerative environment within hair follicles
