Oilseed protein isolates as albumin alternatives for muscle cell culture media

ABSTRACT: The development of cost-effective serum-free media is essential for the development of cell-cultured meat technologies. While some effective media have been developed for relevant cells (e.g., bovine muscle stem cells), these rely on costly recombinant albumin which is too expensive for a scalable system. In this study, we explored bulk protein isolates from rapeseed, cottonseed, and soybean as alternatives to recombinant albumin, and show that rapeseed protein isolate (RPI) is effective in replacing albumin for the serum-free culture of bovine muscle stem cells. We additionally performed proteomic characterization of the three oilseed protein isolates used in the study to compare how proteomic differences might be associated with functional differences between these proteins.

Stimulation of human umbilical venous endothelial cells (HUVECs) with bone morphogenetic protein 4 (BMP4).

Project description:Backround: Several microRNAs have been characterized to regulate the process of angiogenesis. Previously, bone morphogenetic protein 4 (BMP4) was shown to increase the proangiogenic activity of endothelial cells. Aim: In this project we investigated how the proangiogenic BMP4 effect is mediated by microRNAs. Experimental design: To investigate changes in the microRNA transcriptome in HUVECs a time course experiment (12, 18 and 24 h) was performed. HUVECs were kept in endothelial basal medium either with BMP4 (25 ng/ml) stimulation or buffer control (4 mM HCL with 0.1% bovine serum albumin). Comparison between stimulated vs. unstimulated cells at different time points. followed by a miRNA microarray analysis was performed.

Interferon Regulatory Factor 5 represses mitochondrial matrix protein GHITM to limit macrophage oxidative capacity in early response to obesity [bmdm]

Project description:To investigate the involvement of IRF5 in macrophages during obesity-related inflammation, we analyzed bone marrow-derived macrophages stimulated for 2 or 24 hours with Lipopolysaccharide (LPS), Palmitate or carrier (bovine serum albumin), from mice with a myeloid-specific deletion of IRF5 or their wild-type littermates.

Genomics-based molecular epidemiology of human clinical and feedlot cattle C. jejuni isolates in Alberta, Canada

Project description:Oligonucleotide DNA microarrays were used as a platform to compare C. jejuni isolates from feedlot cattle and human clinical cases from Alberta. Comparative genomic hybridization (CGH) analysis was performed on 87 isolates (46 bovine, 41 human) obtained within the same geographical regions and time frame. In addition, We also performed gene association analysis to determine if any genes may be differentially distributed between human and cattle sources or between clusters dominated by either human or cattle isolates (âhuman enrichedâ vs âcattle enrichedâ). Keywords: Comparative Genomic Hybridization; Genomic epidemiology; Gene-association study Data from 119 microarrays is included in the dataset, representing the 89 bacterial strains analyzed (87 field isolates, 2 control laboratory strains). Replicate arrays for 20 of the 87 field isolates were included in the dataset, as well as 5 replicates for each of the 2 laboratory controls. An array representing 1546 ORFs from strain NCTC 11168 was used in CGH experiments. CGH was performed by comparing signal from each Tester field isolate analyzed vs. signal from the Control strain NCTC 11168. Values represent mean of triplicate spots.

Comparative genomic hybridizations of Mycobacterium avium isolates obtained from multiple host species

Project description:A comparative genomic approach was used to identify large sequence polymorphisms among Mycobacterium avium isolates obtained from a variety of host species. DNA microarrays were used as a platform for comparing mycobacteria field isolates with the sequenced bovine isolate Mycobacterium avium subsp. paratuberculosis (Map) K10. ORFs were classified as present or divergent based on the relative fluorescent intensities of the experimental samples compared to Map K10 DNA. Map isolates cultured from cattle, bison, sheep, goat, avian, and human sources were hybridized to the Map microarray. Three large deletions were observed in the genomes of four Map isolates obtained from sheep and four clusters of ORFs homologous to sequences in the Mycobacterium avium subsp. avium (Maa) 104 genome were identified as being present in these isolates. One of these clusters encodes glycopeptidolipid biosynthesis enzymes. One of the Map sheep isolates had a genome profile similar to a group of Mycobacterium avium subsp. silvaticum (Mas) isolates which included four independent laboratory stocks of the organism traditionally identified as Maa strain 18. Genome diversity in Map appears to be mostly restricted to large sequence polymorphisms that are often associated with mobile genetic elements. Keywords: Comparative genomic hybridization Each isolate was competitively hybridized against Map K10 with a minimum of 2 dye flip hybridizations per isolate.

Transcription profiling of T. brucei bloodstream forms cultured in different proportions of fetal bovine serum to investigate iron-sensing mechanisms

Project description:Bloodstream trypanosomes are sensitive to iron starvation, and upregulate ESAG6/7 transferrin receptor (TfR) mRNA and protein levels when placed in low transferrin or iron-depleted media, and adjust TfR expression to compensate for reduced endocytosis. Both observations suggest a specific transcriptional-level response resulting from an iron-sensing mechanism. The transcriptomes of BSFs cultured in different proportions of fetal bovine serum (FBS) were analysed. part 1: 4 biological replicates of SMB cells grown with 10% FBS (normal conditions) and 4 replicates of SMB cells grown with 30% FBS, as well as dye swaps, were used. part 2: 3 biological replicates of SMB cells grown with 10% FBS (normal conditions) and 3 replicates of SMB cells grown without FBS (but supplemented with 5 mg/ml BSA to simulate physiological concentrations of albumin in media with 10% FBS), as well as dye swaps were used. part 3: 3 biological replicates of SMB cells grown with 10% FBS (normal conditions) and 3 replicates of SMB cells grown without FBS (but supplemented with 5 mg/ml BSA and 0.3 mg/ml bovine holo-transferrin to simulate physiological concentrations of albumin and transferrin in media with 10% FBS), as well as dye swaps were used.

Transcriptomic analysis of Caco-2 cells following exposure to VTEC isolates derived from diverse origins

Project description:This project has two goals. Firstly, to compare the gene expression profiles of Caco cells following exposure to Verocytotoxigenic E. coli0157:H7 (VTEC) isolates from food animals (bovine, ovine, porcine) and human in an effort to assess the invasive and toxigenic potential of isolates of different origin. All sources contain the common virulence and type 3 secretory system genes. Secondly, to compare the gene expression profiles of Caco-2 cells following exposure to VTEC isolates that contain (positive) or do not contain (negative) the genes of the type 3 secretory system (TTSS).
