The gene expression of amylase, trypsin, and lipase in the digestive organs of the two-spotted cricket (Gryllus bimaculatus) was tested to understand how it overcomes starvation. Amylase gene expression in the foregut was reduced by digesting no food until starvation-3 days. Although that expression...

Trypsin은 무엇인가? | Trypsin은 chymotrypsin family의 serine endopeptidase로서 음식소화, 면역방어 및 zymogen 활성화를 포함하여 곤충에서 다양한 중요한 역할을 한다. Trypsin 유전자발현은 Aedesaegypti의 instar의 모든 발생과정에 지속된다[34], 그러나 Trypsin 유전자발현의 정확한 메커니즘은 완전하게 알지 못하고 있다[15]. | |
배 발생기원에 따라 곤충의 소화기계는 어떻게 구별되는가? | 소화 효소합성, 분비 및 소화 메커니즘은 기본적으로 모든 동물과 유사하다. 곤충 소화기계는 배 발생기원(embryological origin)에 따라서 전장(foregut), 중장(midgut), 후장(hindgut)으로 구별된다. 전장과 후장은 외배엽(ectoderm)유래로서 각질(cuticle) 층을 가지고 있어 탈피(moulting)과정을 거친다. | |
곤충이 환경 변화로 인한 음식 부족을 극복하는 방법은? | 곤충이 장기간 충분한 음식을 섭취하지 않으면 성장과 번식이 크게 줄어든다. 그러나 곤충은 스트레스 방지 상태로 대응하여 새로운 식품자원의 발견 및 이동, 신진 대사를 제한하는 활동 감소, 신체의 항상성을 유지하기 위한 지질 침착 증가와 같은 불리한 외부음식 부족을 극복 할 수 있다[11, 36]. 기아에 직면하면서 곤충반응에는 혈당, 트레할로스(trehalose) 및 트리글리세리드(triglyceride)수치와 같은 여러 가지 생리학적 변화도 포함된다[13]. |
