Project description:The hypothesis was tested that insect meal (IM) as protein source influences intermediary metabolism of growing pigs. To test this, 5-week-old crossbreed pigs were randomly assigned to 3 groups of 10 pigs each with similar body weights (BW) and fed isonitrogenous diets either without (CON) or with 5 % IM (IM5) or 10 % IM (IM10) from Tenebrio molitor L. for 4 weeks and liver was analyzed using transcriptomics. Transcriptomics of the liver revealed a total of 166 transcripts differentially expressed between IM10 and CON.

Transcriptomics of skeletal muscle revealed a total of 198 transcripts differentially expressed between IM10 and CON.
Project description:The purpose of this study was to investigate the effects of high levels of Tenebrio molitor dietary inclusion (15%) on molecular mechanisms that influence poultry health in a broiler chicken diet.
Project description:This study aimed at integrating metabolomics and proteomics data for a comprehensive view of the molecular targets of intervention of protein extracts from Tenebrio molitor in treating hypertension. Serum samples from spontaneously hypertensive rats and Wistar Kyoto rats were analyzed using a quantitative metabolomics and label-free proteomics approach based on liquid chromatography coupled with high resolution mass spectrometry (LC-HRMS). Among deregulated metabolites and proteins in hypertensive rats, we found 15 metabolites and 17 proteins that were restored by supplementation with Tenebrio molitor protein extract. The combination of metabolomics and proteomics provided useful data to uncover the molecular targets of intervention and the underlying functional mechanism of Tenebrio molitor protein extract in an animal model such as spontaneously hypertensive rats. The results suggested that Tenebrio molitor supplementation could effectively treat hypertension, partially by regulating proteins and molecules mainly involved in biological pathways associated to angiotensinogen-angiotensin, Serin protease inhibitors, kallikrein–kinin, reactive oxygen scavenging, and lipid peroxidation.

Project description:Tenebrio molitor larval gut sequencing
Project description:This study was designed to address key questions concerning the use of alternative protein sources for animal feeds and addresses aspects such as their nutrient composition and impact on gut function. We used casein (CAS), spray dried porcine plasma (SDPP), soybean meal (SBM), and yellow meal worm (YMW) as protein sources. We have investigated the use of intestinal organoids as a model to test the effects of different protein sources on the intestinal epithelium. Mouse enteroids were exposed to different undigested protein sources (4% w/v, viz. soybean meal, SBM; casein, CAS; spray dried plasma protein, SDPP; and yellow meal worm, YMW) or DMEM as a control. Microarrays were used to detail the global gene expression.
