The present study was conducted to evaluate the hair growth-promoting effect of Clitocybin A from mushroom Clitocybe aurantiaca with dermal papilla cells (DPCs), which play important roles in the regulation of hair cycle. Clitocybin A significantly increased the proliferation of immortalized rat vib...

모유두 세포란? | Clitocybin A가 모유두 세포의 성장증식 효능이 있는지 불멸화된 모유두 세포를 사용하여 조사하였다. 모유두 세포는 모낭의 기저에 위치하는 중배엽 유래 세포로써, 모기질 세포(matrix cells)와의 상호작용, hair germ을 통한 stem cell 활성화 및 모발의 재생에 중요한 작용을 한다고 알려져 있다.12,16,29,30) Clitocybin A을 0. | |
Wnt/β-catenin 신호전달 경로는 어떤 과정에서 중요한 역할을 하는가? | Clitocybin A가 모유두세포의 성장 증식을 유도하는 분자적 기전을 밝히기 위해 Wnt/β-catenin 신호 전달 경로에 관하여 조사하였다. Wnt/β-catenin 신호전달 경로는 모발성장, 세포증식 조절등의 과정에서 중요한 역할을 하며, 6,10,31) PKA, Akt 및 GSK3β 등의 다양한 인자에 의해 조절됨이 알려져 있다. Akt의 활성화는 β-catenin의 인산화(ser552) 및 GSK3β의 인산화(ser9)를 유도하며, PKA는 β-catenin의 인산화(ser552 및 ser675)를 유도하여 세포질 내에서 β-catenin의 분해를 저해하고 안정화를 증가시킨다. |
