Improved isolation of good-quality total RNA from the optic stalk of Mud crab, Scylla paramamosain Electron. J. Biotechnol.
Zhu,Houze; Jiang,Keji; Zhang,Fengying; Zhang,Dan; Pi,Yan; Ma,Lingbo.
An improved and efficient protocol was developed based on the TaKaRa RNAiso Plus Kit (Code: D9108A) for isolating good-quality total RNA from the optic stalk of mud crab, Scylla paramamosain. The protocol was based on the Trizol method with modifications. The carapace overlapping the optic stalk was retained with RNA in regular protocol. In order to remove the abundant deposition correlative with the carapace which makes the isolation of RNA particularly difficult, 5M potassium acetate solution (pH = 6.0) was added before the precipitation of RNA, and the temperature of RNA deposition was also decreased to -70ºC to ensure the stabilization of RNA. Good-quality total RNA from the optic stalk of S. paramamosain could be easily isolated with this modified...

Molecular cloning and functional analysis of the fatty acid-binding protein (Sp-FABP) gene in the mud crab (Scylla paramamosain) Genet. Mol. Biol.
Zeng,Xianglan; Ye,Haihui; Yang,Ya'nan; Wang,Guizhong; Huang,Huiyang.
Intracellular fatty acid-binding proteins (FABPs) are multifunctional cytosolic lipid-binding proteins found in vertebrates and invertebrates. In this work, we used RACE to obtain a full-length cDNA of Sp-FABP from the mud crab Scylla paramamosain. The open reading frame of the full length cDNA (886 bp) encoded a 136 amino acid polypeptide that showed high homology with related genes from other species. Real-time quantitative PCR identified variable levels of Sp-FABP transcripts in epidermis, eyestalk, gill, heart, hemocytes, hepatopancreas, muscle, ovary, stomach and thoracic ganglia. In ovaries, Sp-FABP expression increased gradually from stage I to stage IV of development and decreased in stage V. Sp-FABP transcripts in the hepatopancreas and hemocytes...

Characterization and expression analysis of chymotrypsin after bacterial challenge in the mud crab, Scylla paramamosain Genet. Mol. Biol.
Gong,Jie; Xie,Yinjie; Yu,Kun; Yang,Ya'nan; Huang,Huiyang; Ye,Haihui.
Chymotrypsin is one of the serine proteases families that have various biological functions. A chymotrypsin gene was isolated from hepatopancreas of the mud crab, Scylla paramamosain (designated SpCHY) in this study. The full-length cDNA of SpCHY contained 942 nucleotides with a polyadenylation sequence and encoded a peptide of 270 amino acids with a signal peptide of 17 amino acids. The SpCHY gene contains seven exons, six introns, a TATA box and several transcription factor binding sites that were found in 5'-promoter region which is 1221 bp in length-time quantitative PCR analysis indicated that the expression level of SpCHY mRNA in hepatopancreas was significantly higher than that in other tissues. Immunocytochemistry and in situ hybridization...
