Project description:Mandarin fish Siniperca chuatsi (Basilewsky) (Percichthyidae), as a demersal piscivore, has very specialized feeding habits, for as soon as they start feeding the fry of this fish feed solely on fry of other fish species. In rearing conditions, mandarin fish has been found to accept live prey fish only, and refuse dead prey fish or artificial diets, very little is currently known about the molecular mechanisms of multiple genes which cover different pathways influencing the specialized food habit, such as live prey. We performed transcriptome comparisons between dead prey fish feeders and nonfeeders in mandarin fish. The determination mechanisms of specialized food habit (live prey fish) in mandarin fish could provide some instructions for research of food habit in animals, including mammals.

Project description:In the context of replacing fish meal and fish oil in feeds for aquaculture, rainbow trout alevins received from first-feeding onwards, one of the three experimental diets: V (100% plant-based), C (mix of FM-FO & plant ingredients) or M (100% FM-FO based). The long term effects of such dietary replacement on the intestinal (mid gut) and hepatic transcriptome were studied in juveniles after a 7-month feeding trial at 7°C.

Project description:Many studies estimate that chromosomal mosaicism within the cleavage stage human embryo is high. However, comparison of two unique methods of aneuploidy screening of blastomeres within the same embryo has not been conducted and may indicate whether mosaicism is overestimated due to technical inconsistency rather than biological phenomena. The present study investigates the prevalence of chromosomal abnormality and mosaicism found with two different single cell aneuploidy screening techniques.Thirteen arrested cleavage stage embryos were studied. Each was biopsied into individual cells (n=160). The cells from each embryo were randomized into two groups. Those destined for FISH based aneuploidy screening (n=75) were fixed, 1 cell per slide. Cells for SNP microarray based aneuploidy screening (n=85) were put into individual tubes. Microarray was significantly more reliable (96%) than FISH (83%) for providing an interpretable result (P=0.004). Markedly different results were obtained when comparing microarray and FISH results from individual embryos. Mosaicism was significantly less commonly observed by microarray (4 of 13 embryos; 31%) than by FISH (13 of 13 embryos; 100%)(P=0.0005). Although FISH evaluated fewer chromosomes per cell and fewer cells per embryo, FISH still displayed significantly more unique genetic diagnoses per embryo (3.2+0.2) than microarray (1.3+0.2)(P<0.0001). This is the first prospective, randomized, blinded, and paired comparison between microarray and FISH based aneuploidy screening. Aneuploidy and mosaicism were less common with microarray. While evaluating a smaller number of chromosomes with a proportionally smaller opportunity for finding mosaicism, FISH still had a dramatically higher level of inter-cell variation in diagnosis. SNP microarray based 24 chromosome aneuploidy screening provides more complete and consistent results than FISH.
