Project description:The present study was conducted to investigate the effect of graded levels of black soldier fly larvae (BSFL) (Hermetia illucens) meal and BSFL paste in extruded diets for Atlantic salmon (Salmo salar). A total of 1260 Atlantic salmon with 34 g of mean initial weight were randomly distributed into 21 fiberglass tanks and fed (n=3) with seven extruded isolipidic and isonitrogenous diets for seven weeks. The experimental diets consisted of a positive control diet based on fishmeal, soy protein concentrate, corn gluten, faba bean and fish oil (Control_1); three diets with increased levels of full lipid BSFL meal, substituting 6.25% (6.25_IM), 12.5% (12.5_IM) and 25% (25_IM) of the protein content of Control_1; two diets with increased levels of full lipid BSFL paste, substituting 3.7% (3.7_IP) and 6.7% (6.7_IP); and of protein from Control_1 and a negative a control with 0.84 % of formic acid (Control_2). We investigate the effect of diets on growth performance, mmune response and health.
Project description:pin1 mutnat doesn't produce any floral organs, which can be rescued by exogenous application of IAA paste. Here we applied exogenous IAA paste and collected meristem tissue after different time points (30 min, 4hr, 12hr, 16hr). As a control we applied mock paste. Around 10 meristems were dissected under dissecting scope for each biological replicate. Some known IAA inducible genes were checked for their upregulation in extracted RNA, and there after the RNA was sequenced.
Project description:Soy-based diets have triggered the interest of the research community due to their beneficial effects on a wide variety of pathologies like breast and prostate cancer, diabetes, and atherosclerosis. However, the molecular details underlying these effects are far from being completely understood and several recent attempts have been made to elucidate the soy-induced liver transcriptome changes in different animal models. Here we used Next Generation Sequencing to identify a set of two microRNAs specifically modulated by short-term soy-enriched diet in young male mice and estimate their impact on the liver transcriptome assessed by microarray. Clustering and topological community detection (CTCD) network analysis of STRING generated interactions of transcriptome data led to the identification of five topological communities of genes characteristically altered and putatively targeted by microRNAs upon soy diet intervention.
Project description:To investigate the effect of soy peptides on gut microial composition during juvenile social isolation, group-house (GH) and social isolation (SI) mice were fed a diet consisting of soy peptides or a control diet for 4 weeks post-weaning. We then performed microbial community analysis using data obtained from bacterial 16S rRNA gene sequencing in the fecal samples of 4 mice groups (control diet-fed GH, soy peptide-diet fed GH, control diet-fed SI, and soy peptide-diet fed SI mice).
Project description:Epidemiologic studies demonstrate that women from cultures that consume high levels of dietary soy have reduced breast cancer rates compared to women from cultures where soy consumption is typically much lower. The types of soy products consumed can also differ with Asian cultures consuming primarily minimally refined soy products while Western cultures often consume more highly refined soy products such as isolated soy protein (ISP). Our previous work showed that lifetime exposure to a diet containing 20% ISP promoted mammary tumor development in MTB-IGFIR transgenic mice. In this study, lifetime exposure to lower levels of ISP were evaluated (5% ISP and 1% ISP) to determine whether more moderate levels of ISP could protect against mammary tumorigenesis. A standard rodent diet, Teklad 2018 was also included in this study and Teklad 2018 contains a less refined form of soy, namely soybean meal. MTB-IGFIR mice fed ISP diets, independent of the concentration, displayed increased mammary tumor incidence and reduced tumor latency compared to MTB-IGFIR mice fed a 20% casein diet. Unexpectedly, MTB-IGFIR mice fed Teklad 2018 were completely protected against mammary tumor development. Although RNA sequencing of mammary tumors from ISP or casein fed mice did not identified gene expression patterns associated with the ISP diets, the ISP diets consistently promoted the expression of contractile related proteins in pubertal mammary glands. Therefore, lifetime exposure to ISP may alter gene expression in pubertal mammary glands rendering them more susceptible to transformation. Based on these findings women may want to avoid highly refined soy products such as ISP and switch to less refined forms of dietary soy until additional studies can be performed.

Project description:Female Atlantic cod (Gadus morhua)were devided in to five groups and oraly exposed to alkylphenols and produced water for 20 weeks. Differentially expressed genes were studied in liver samples using the CodStress array. The five groups were fed with feed-paste containing two different doses of the AP mixture (Low AP and High AP), PW, 17?-estradiol (E2) and toxicant-free paste (control group) respectively. The body burden for each compound corresponded to 20 ?g/kg of total AP in Low AP group, 4000 ?g/kg ?g/kg of total AP in High AP group, 100 ?g E2/kg in the E2 group 500 mg PW/kg in the PW group.
