Agaricus blazei mycelial liquid culture extract (ABMLCE) promoted the production of testosterone (TS) in TM-3 mouse Leydig testis cells. Now, we report that ABMLCE containing eritadenine (EA) as a minor constituent (15.3 mg/100 g) reduced

신령버섯의 어떤 특징을 가진 버섯인가? | 신령버섯(Agaricus blazei Murill, AB)은 β-D-glucan, polyphenol, eritadenine (EA) 등과 같은 수많은 2차대사산물을 함유하고 있어, 항암성, 항산화성, 면역성 등의 기능성이 뛰어난 약용버섯이다[3, 8-10, 14, 17, 37]. 이와 같은 효능을 갖는 AB자실체 생산은 오랜 생육기간을 요하고, 배지조성이나 배양조건 등이 까다롭기 때문에, AB자실체를 생산하는 대신 화학적 성분이나 기능성이 유사한 AB균사체를 액체배양하여 활용하고 있다[5, 7]. | |
AB균사체 액체배양 추출물이 RWPE-1 세포에 미치는 영향은? | 본 연구에서 ABMLCE가 RWPE-1 전립선세포의 BPH 예방 및 치료를 위한 핵심 효소인 5α-R2 효소활성을 감소시킴과 동시에 핵심 물질인 DHT 함량을 감소시킴을 확인하였다. 이와 같은 효과는 ABMLCE의 항염증효과(COX-2 효소활성 감소, TNF-α와 IL-1b 함량 감소)와 항산화효과(SOD 효소 및 CAT 효소활성 증가)에 기인하며, EA가 이들 효과에 관여함을 확인하였다(Fig. | |
전립선비대증의 주원인 및 유발 물질은 무엇인가? | 전립선비대증(Benign prostatic hyperplasia: BPH)의 주원인은 노화, 산화스트레스 및 염증반응 등이 있으며[4, 6, 23, 33], BPH는 전립선 조직내의 dihydrotestosterone (DHT)에 의해 유발된다[31]. 고환의 Leydig cell에서 합성된 TS가 전립선 조직으로 유입되어 5α-reductase 2 (5α-R2)의 작용에 의해 DHT로 전환된다. |
