چکیده

Deltamethrin is an important pesticide widely used against ectoparasites. Deltamethrin contamination has resulted in a threat to the healthy breeding of the Chinese mitten crab, Eriocheir sinensis. In this study, we investigated transcriptional responses in the hepatopancreas of E. sinensis exposed to deltamethrin. We obtained 99,087,448, 89,086,478, and 100,117,958 raw sequence reads from control 1, control 2, and control 3 groups, and 92,094,972, 92,883,894, and 92,500,828 raw sequence reads from test 1, test 2, and test 3 groups, respectively. After filtering and quality checking of the raw sequence reads, our analysis yielded 79,228,354, 72,336,470, 81,859,826, 77,649,400, 77,194,276, and 75,697,016 clean reads with a mean length of 150 bp from the control and test groups. After deltamethrin treatment, a total of 160 and 167 genes were significantly upregulated and downregulated, respectively. Gene ontology terms "biological process," "cellular component," and "molecular function" were enriched with respect to cell killing, cellular process, other organism part, cell part, binding, and catalytic. Pathway analysis using the Kyoto Encyclopedia of Genes and Genomes showed that the metabolic pathways were significantly enriched. We found that the CYP450 enzyme system, carboxylesterase, glutathione-S-transferase, and material (including carbohydrate, lipid, protein, and other substances) metabolism played important roles in the metabolism of deltamethrin in the hepatopancreas of E. sinensis. This study revealed differentially expressed genes related to insecticide metabolism and detoxification in E. sinensis for the first time and will help in understanding the toxicity and molecular metabolic mechanisms of deltamethrin in E. sinensis.

Metabolism and Elimination of Oxytetracycline in Hepatopancreas of Chinese Mitten Crab Eriocheir Sinensis

The kinetic profiles of Oxytetracycline (OTC) in hepatopancreas of Eriocheir sinensis was examined in this research. The results showed that after a single-dose of 40 mg/kg body weight OTC at (18±1°C) by intramuscular administration, the hepatopancreas concentration-time curve of OTC could be best described by a one-compartment model with first-order absorption and a time lag: C = 69.45×(e-0.00...

Effect of dietary histamine supplementation on growth, digestive enzyme activities and morphology of intestine and hepatopancreas in the Chinese mitten crab Eriocheir sinensis

A 28-days feeding experiment was conducted to investigate the effect of histamine on digestive physiology of the Chinese mitten crab, Eriocheir sinensis. Four experimental diets were supplemented with histamine at 0, 1, 2, 4 g/kg. Histamine supplementation had no effect on growth. The activities of digestive enzyme decreased significantly at first (days 7 and 14) (p < 0.05) and then increased o...

The site of vitellogenin synthesis in Chinese mitten-handed crab Eriocheir sinensis.

The objective of this study was to investigate the synthesis site of vitellogenin in the Chinese mitten-handed crab, Eriocheir sinensis. Using the RT-PCR techniques, the cDNA fragments isolated from the ovaries of vitellogenic female crab, we found that its deduced amino acid sequence had a high identity with that from other decapods crustacean vitellogenin. This cDNA fragments were used as pro...

A novel C-type lectin from Eriocheir sinensis functions as a pattern recognition receptor with antibacterial activity.

As pattern recognition receptors (PRRs), C-type lectins (CTLs) play significant roles in recognizing and eliminating pathogens in innate immunity. In this study, a novel CTL (EsLecD) was identified from the crustacean Eriocheir sinensis. The cloning of full-length EsLecD cDNA was based on the initial expressed sequence tags (ESTs) isolated from a hepatopancreatic cDNA library. The full-length E...

Transcriptomic variation of hepatopancreas reveals the energy metabolism and biological processes associated with molting in Chinese mitten crab, Eriocheir sinensis

Molting is a critical developmental process for crustaceans, yet the underlying molecular mechanism is unknown. In this study, we used RNA-Seq to investigate transcriptomic profiles of the hepatopancreas and identified differentially expressed genes at four molting stages of Chinese mitten crab (Eriocheir sinensis). A total of 97,398 transcripts were assembled, with 31,900 transcripts annotated...
