Actin is a highly conserved protein that is found in all eukaryotic cells, and has been widely used as an internal control gene in gene expression studies. In this study, we cloned an actin gene (named Ecβ-actin) from Exopalaemon carinicauda and determined its expression levels. The full-length cDNA of Ecβ-actin was 1335 bp long, comprising a 1131-bp ORF encoding 376 amino acids, a 65-bp 5'-UTR, and a 139-bp 3'-UTR with a poly(A) tail.

Screening of genes related to ovarian development in the swimming crab, Portunus trituberculatus, by suppression subtractive hybridization

Z. B. Yu, Mu, C. K., Song, W. W., Li, R. H., Chen, Y. E., and Wang, C. L., Screening of genes related to ovarian development in the swimming crab, Portunus trituberculatus, by suppression subtractive hybridization, vol. 14, pp. 18675-18686, 2015.

The swimming crab, Portunus trituberculatus, is an important marine animal and is widely cultured in China. In the present study, suppression subtractive hybridization was applied to identify the differentially expressed genes in the ovaries of mature and immature P. trituberculatus. One hundred and seventy six expressed sequence tag (ESTs) were identified, of which 100 were down-regulated, and 76 up-regulated. BLAST analysis identified 51 unigenes, of which 27 were down-regulated, and 24 up-regulated.
