Advances in understanding the mitogenic, metabolic, and cell death signaling in teleost development: the case of greater amberjack (Seriola dumerili, Risso 1810) - Fish Physiology and Biochemistry
Cell growth and differentiation signals of insulin-like growth factor-1 (IGF-1), a key regulator in embryonic and postnatal development, are mediated through the IGF-1 receptor (IGF-1R), which activates several downstream pathways. The present study aims to address crucial organogenesis and development pathways including Akt, MAPKs, heat shock response, apoptotic and autophagic machinery, and energy metabolism in relation to IGF-1R activation during five developmental stages of reared Seriola dumerili: 1 day prior to hatching fertilized eggs (D-1), hatching day (D0), 3 days post-hatching larvae (D3), 33 (D33) and 46 (D46) days post-hatching juveniles. During both the fertilized eggs stage and larval-to-juvenile transition, IGF-1R/Akt pathway activation may mediate the hypertrophic signaling, while p44/42 MAPK phosphorylation was apparent at S. dumerili post-hatching processes and juvenile organs completion. On the contrary, apoptosis was induced during embryogenesis and autophagy at hatching day indicating a potential involvement in morphogenetic rearrangements and yolk-sac reserves depletion. Larvae morphogenesis was accompanied by a metabolic turnover with increased substantial energy consumption. The findings of the present study demonstrate the developmental stages-specific shift in critical signaling pathways during the ontogeny of reared S. dumerili.

MasahitoSato先週の土曜日、日本語を教えている生徒とThanksgivingの話をしたとき、手巻き寿司でもやろうかなあと思っていると私が言うと、生徒が旦那が戻ってきたらメイン州のポートランドまでお刺身とか買いに行くからシェアしようということになったんです。でも買いに行ったのが土曜日だったのでThanksgivingは別の料理になったわけです。で、今日は息子もいっしょに手巻き寿司にするつもり。
ポートランドの店の名前はISF Trading。経営者はたぶん日本人。メニューも日本語。客もほとんど日本人みたいです。ホタテ、ウニは確実に、そしてたぶん鯖も地元産。マグロも地元産の可能性あり。ちなみにメイン州はウニを大量に日本に輸出しています。
