Project description:In the present study, the eggs of Chinese pond turtles (Mauremys reevesii) were incubated at three temperatures (26℃, 29℃ and 32℃). During the thermosensitive period (TSP) of incubation, the adrenal-kidney-gonad (AKG) complexes were sampled, and a comprehensive investigation for miRNAs was performed using next-generation small RNA sequencing.
Project description:Rainbow trout (Oncorhynchus mykiss) is an important aquaculture fish species that is farmed worldwide, and it is also the most widely cultivated cold water fish in China. This species, a member of the salmonidae family, is an ideal model organism for studying the immune system in fish. Two phenotypes of rainbow trout are widely cultured; wild-type rainbow trout with black skin (WR_S) and yellow mutant rainbow trout with yellow skin (YR_S). Fish skin is an important immune organ, however, little is known about the differences in skin immunity between WR_S and YR_S in a natural flowing water pond aquaculture environment, and very few studies were conducted to investigate the ceRNA mechanism for fish skin.
Project description:The primary goal of this project is to monitor host global gene expression patterns in response to viral infection in the shrimp, Litopenaeus stylirostris. Specific Pathogen Free (SPF) L. stylirostris were obtained from High Health Aquaculture (Honolulu, Hawaii) and kept in environmentally controlled tanks. For control, animals were injected with saline (30 ul) between the second and third tergal plates of the lateral side of the tail using a 1 ml tuberculin syringe. Infected individuals were inoculated with homogenate created from IHHNV infected shrimp tissue. After 24 hours, the shrimp were sacrificed and tissue was collected from the ventral and flash frozen in liquid nitrogen and stored in the -80 ºC freezer. Libraries of sequence tags were generated via the Long-SAGE kit (Invitrogen®, Carlsbad, CA) until the ditag PCR preparation step and directly pyrosequenced by 454 Roche.
