Numerous factors can affect the activities of hypothalamus-pituitary-gonad (HPG) hormonal axis, resulting in alteration of reproductive capacity or status such as onset of puberty and menopause. Soon after the finding of leptin, a multifunctional hormone secreted from adipocytes, a close relationshi...

ghrelin 수용체는 어떤 신체 기관에서 발현하는가? | , 2005). GHSR1a는 뇌의 몇몇 nucleus, 뇌하수체에서 다량 발현되며, 갑상선, 췌장, 비장, 심근, 부신 그리고 생식소에서도 발현되며, GHSR1b 역시 이와 유사한 발현 양상을 보였다(Guan et al., 1997; Tena-Sempere et al. | |
preproghrelin 전구체는 어떤 염색체에 있는 유전자에 의해 암호화되어 있는가? | 초기 연구에서 인간의 preproghrelin 전구체는 3번 염색체 short arm(3p26-p25)에 위치한 GHRL 유전자에 의해 암호화 되고, 4개의 exon(exon 1~4)으로 구성되었다고 보고되었다(Kojima et al., 1999). | |
ghrelin 수용체의 두 종류는 무엇인가? | 현재까지 알려진 ghrelin 수용체는 두 종류로, 각각 GHSR1a와 GHSR1b이다. GHSR1a는 366개의 아미노산으로 구성되며, 7개의 막관통 도메인(transmembrane domain)을 갖는 전형적인 G protein-coupled receptor(GPCR)이며(Kojima et al. |
