Expression patterns of two heat-shock cognate 70 genes during immune responses and larval development of the Chinese mitten crab Eriocheir sinensis

P. Li, Jiang, X. F., Guo, W. B., Yan, J., Zhou, K. Y., Li, P., Jiang, X. F., Guo, W. B., Yan, J., and Zhou, K. Y., Expression patterns of two heat-shock cognate 70 genes during immune responses and larval development of the Chinese mitten crab Eriocheir sinensis, vol. 15, p. -, 2016.

Two heat-shock protein (HSP) 70 family transcripts, heat-shock protein 70 cognate 5 and heat-shock protein 70 cognate 3 (designated as EsHSC70-5 and EsHSC70-3, respectively), were isolated from the Chinese mitten crab Eriocheir sinensis and their expression profiles were evaluated for their responsiveness to larval development and immune challenge in adult crabs. The HSPs exhibited 45-89% identity with other heat-shock proteins, and they shared similar structural features.

Genetic variations in the UTR of genes related to molting in Eriocheir sinensis

X. G. Gao, Pu, H. S., He, C. B., Bao, X. B., and Liu, W. D., Genetic variations in the UTR of genes related to molting in Eriocheir sinensis, vol. 14, pp. 12472-12478, 2015.

Crab grows by periodic molting, which is controlled by molt-inhibiting hormone (MIH) and ecdysteroids. Untranslated regions (UTRs) play crucial roles in the posttranscriptional regulation of gene expression. In this study, using crab collected from Changjiang (Yangtze), Huanghe (Yellow), Liaohe, and Yalujiang rivers, 33 haplotypes of the 3ꞌ-UTR of ecdysteroid-regulated protein (ERP) gene were identified, of which 14 haplotypes were observed in more than one individual. One hundred and forty clones of haplotype h2 (41.5%) were observed in samples from all the 4 rivers.
