A novel neuropeptide was isolated from the skin of the snakehead Channa argus using the dorsal retractor muscle (DRM) of a starfish Asterina pectinifera as a bioassay system. The amino acid sequence of the purified peptide was analyzed using automated sequencing and MALDI-TOF mass spectrophotometry....

Neuropeptide는 어떤 역할을 담당하는가? | 신경성 펩타이드들(neuropeptides)은 1962년 낙지의 타액선으로부터 eledosin이 발견된 이후(Erspamer and Anastasi, 1962) 무척추 하등동물에서부터 인간에 이르기까지 다양한 생물의 조직으로부터 발견되어졌다(Krieger, 1986). Neuropeptide는 보통 4-30개정도의 아미노산으로 구성된 물질로 생체 내에서 호르몬 혹은 비호르몬으로서 다양한 기관 및 조직에 따라 평활근의 운동조절, 혈관의 수축 및 이완, 통증전달 및 혈압조절 등의 역할을 담당하고 있는 neuromodulator 및 neurotransmitter이다(Brown, 1994; Shuttleworth et al., 1995; Zadina et al. | |
가물치는 미국산 물고기 중 어떤 종과 유사하게 생겨 혼동되기 쉬운가? | 가물치(Channa argus)는 농어목(Perciformes) 가물치과의 등목어류에 속하는 토종 민물고기로, 연못이나 늪처럼 흐리고 고여 있는 저수지나 늪 등 주로 탁한 물이 있는 얕은 곳을 좋아해서 깊이가 1미터 안팎이고 물풀이 우거진 곳에 서식한다(Okada, 1960; Courtenay and Williams, 2004). 또한 가물치는 육식성으로 주로 물고기, 개구리, 갑각류 및 수서곤충 등을 잡아먹으며, 먹이가 부족하면 동족인 가물치 새끼도 잡아 먹는다고 알려져 있으며(Dukravets and Machulin, 1978; Okada, 1960), 미국산 물고기인 Bowfin Amia calva과 Burbot Lota lota와 유사하게 생겨 혼동되기 쉽다. 한편 가물치는 성장속도가 무척 빨라 한국에서는 식용으로 활용하기 위해 양어장에서 기르는 중요한 어종 중의 하나이다. | |
