Project description:food waste & fish MBM-BSFL frass
| PRJNA758603 | ENA
Project description:Frass is the by-product of the larval meal industry and includes larval waste, exoskeleton sheds, and residual feed ingredients. Experimental frass was derived from the larvae of black solder flies (Hermetia illucens) fed distillers dried grains. A 10-week study was conducted to evaluate the effect of dietary levels of frass on the global gene expression of channel catfish, Ictalurus punctatus. Three diets containing 0, 50, and 300 g frass per kg diet were fed to channel catfish (5.24 ± 0.04 g) in quadruplicate aquaria to apparent satiation twice daily. Intestine (n=12 in pools of 3) and liver (n=12 in pools of 3) tissues were taken from fish at the end of the trial and processed for high-throughput Illumina RNA sequencing (RNAseq). Pairwise comparisons identified both up- and down-regulated genes in frass diets compared to no frass controls.

Project description:Black soldier fly larvae meal (BSFL) from Hermetia illucens is a promising alternative protein source in diets for farmed fish. The larvae can efficiently convert low-value organic material into high quality protein in a production cycle with low arable land and freshwater inputs. A few recent studies have shown that BSFL is a suitable protein source for Atlantic salmon (Salmo salar) in smaller controlled experiments. However, industry-relevant field trials conducted under large scale near-commercial conditions over a longer period are lacking. In this study, a feeding trial was performed to evaluate the impact of BSFL on growth performance and health of Atlantic salmon during the grow out phase in seawater, in a commercial site in Vestland county, Norway. A total of 320,000 post-smolt Atlantic salmon were distributed into six duplicate sea cages and fed one of three diets (commercial-like control diet and two test diets partially replacing the protein content of the control diet with 4 % and 8 % defatted BSFL meal) for 21 weeks, until a relevant commercial slaughter size of 4.5-5.0 kg was reached. Health parameters were assessed including histology of the distal intestine (DI), in addition to DI microbiota identification (by 16s rRNA-seq) and salmon RNA-seq of DI and head kidney (HK). The results showed that the inclusion of BSFL meal supported growth performance and had no adverse effect on gut health. The beta diversity of the distal intestine microbiota and the relative abundance of families Lactobacillaceae and the chitinolytic Bacillaceae increased in the fish fed the BSFL diets. Additionally, no histopathological changes were attributable to BSFL meal intake. Results from RNA-seq in DI revealed that BSFL inclusion modulates metabolic processes associated with lipids, the response to estrogens, the activity of immune receptors (to chemokines), phagocytosis and extracellular vesicles. Based on these results, black soldier fly larvae meal is a suitable alternative protein ingredient in inclusions of up to at least 8 % for Atlantic salmon under industrial fish farming conditions.

Project description:Contamination of food products with mycotoxins such as aflatoxin B1 (AFB1) poses a severe risk to human health. Larvae of the black soldier fly (BSFL), Hermetia illucens (Diptera: Stratiomyidae), can successfully metabolize AFB1 without any negative consequences on their survival or growth. However, the underlying mechanisms that allow BSFL to metabolize AFB1 are unknown. In this study, five-day-old BSFL were fed with either a control or an AFB1-spiked (20 µg/kg) diet to elucidate the underlying mechanisms. Larval samples were collected at three timepoints (6 h, 24 h, and 72 h) and subjected to RNA-Seq analysis to determine gene expression patterns. Provision of an AFB1-spiked diet resulted in an up-regulation of 357 and a down-regulation of 929 unique genes. Upregulated genes include multiple genes involved in AFB1 metabolism in other (insect) species. Downregulated genes were generally involved in the insects' growth, development, and immunity. BSFL possesses a diverse genetic arsenal that encodes for enzymes capable of metabolizing AFB1 without trade-offs on larval survival.

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:A total of 49.88 Gb high quality reads of 6 samples (n=3) were obtained. The result of sample distance indicated that the cecal gene expression profiles of rats fed with diets composed of casein and chicken protein were clearly separated into two clusters. The variation of samples in casein protein fed group was higher than that in chicken protein fed group. There were 2524 differential expressed genes between the two groups, of which 871 genes were up regulated in chicken protein diet group compared with casein diet group.

Project description:Brain metastases (BrMs) are a devastating complication of solid tumors with challenging clinical management. In this study, immunogenomic and digital spatial analyses were applied to interrogate the peripheral blood and tumor specimens derived from 53 unique patients with metastatic brain tumors originating from different solid tumors including melanoma, breast cancer, lung cancer and renal cell carcinoma. In the peripheral blood, lower levels of neutrophil -lymphocytes ratio (NLR) were detected at time of craniotomy in patients with melanoma-derived brain metastasis (MBM) vs. non-melanoma- derived brain metastasis (non-MBM). Independently from the primary tumor of derivation, patients with BrMs and increased NLR levels were characterized by shorter overall survival (OS) following craniotomy. In the tumor microenvironment (TME), molecular evaluations performed on FFPEs revealed higher expression of genes and mRNA signatures identifying NK cells, CD8 cells and B cells in MBM (n=13) vs. non-MBM brain metastasis (n=41). Focusing on CD8 cells, higher infiltration of CD8+ cells were observed in patients with MBM with longer OS following craniotomy. Spatial proteomic analysis further highlighted the infiltration of CD8+ cells, antigen presenting cells- (HLA-DR+, CD11c+, B2M+), agonists of T cell activity (CD137+, CD40+) and B cells (CD20+) enriched in MBM vs non-MBM. On the contrary, an increased expression of genes associated with neuro-development, cell- cell adhesion, neutrophil enrichment together with the increased infiltrations of cells promoting neuro-differentiation (Neun+, S100+), immune regulatory functions (CD25+, CD127+), and granulocytes aggregation (CD66b+) were observed in non-MBM vs. MBM. These findings highlight that the TME of BrMs plays a pivotal role in the pathogenesis and therapeutic resistance of BrMs derived from different solid tumors. Our results also suggest that distinct neuro-immune interplay may contribute to treatment resistance in BrMs.
