Project description:To investigate the central control of water homeostasis in the dromedary camel, we have performed transcriptomic studies on the supraoptic nucleus samples from camels under control (water ad libitum) and dehydrated (water deprivation for 20 days) conditions by RNA sequencing. We have identified genes that change in expression in response to hyperosmotic challenge and transcriptomic response networks that might be essential for adaptations of camel to live and thrive in aird desert environment.

Project description:Camel milk is widely characterized with regard to caseins and whey proteins. However, in camelids, close to nothing is known about the Milk Fat Globule Membrane (MFGM), the membrane surrounding fat globules in milk. The purpose of this study was thus to identify MFGM proteins from Camelus dromedarius milk. Major MFGM proteins (namely, fatty acid synthase, xanthine oxidase, butyrophilin, lactadherin, and adipophilin) already evidenced in cow milk were identified in camel milk using mass spectrometry. In addition, a 1D-LC-MS/MS approach led us to identify 322 functional groups of proteins associated with the camel Milk Fat Globule Membrane. We hope that these findings will contribute to a better characterization of camel milk and to an improved understanding of lipid droplet formation in the mammary epithelial cell.

Project description:Demand for camel milk (CM) is increasing worldwide, due to its high nutritious value and health benefits. In this study, whole CM powders were produced by spray drying (SD) at six inlet temperatures (190°C - 250°C) and by freeze drying (FD). Physicochemical and functional properties of CM powder proteins were investigated. Both treatments had negative effect on casein solubility, while whey proteins remained soluble and slightly increased its solubility with the extent of MR. The CM powders obtained at higher inlet temperatures demonstrated improved antioxidant activity. Secondary structure of whey proteins did not differ among the samples, while surface hydrophobicity of whey proteins was higher in all SD than in FD samples, suggesting only limited denaturation of camel whey proteins at higher inlet temperatures of drying. Thus, the effects of SD under the conditions applied in our study did not decrease camel whey protein solubility, while drying procedure itself regardless of temperature decreased solubility of camel milk caseins. This study provides useful insights for optimization of CM powder production.

Project description:The one-humped Arabian camel (Camelus dromedarius) is the most important livestock animal in arid and semi-arid regions and continues to provide basic necessities to millions of people. In the current context of global warming, there is renewed interest in the adaptive mechanisms that enable camelids to survive in arid conditions. Recent investigations described genomic signatures that revealed evolutionary adaptations to desert environments. We now present a comprehensive catalogue of the transcriptomes and proteomes of the dromedary kidney and describe how the gene expression profiles of Differentially Expressed Genes (DEGs) are modulated as a consequence of chronic dehydration and subsequent acute rehydration. We performed RNAseq and quantification of peptides in samples from 15 dromedaries (5 controls, 5 dehydrated and 5 rehydrated). Gene Ontology analyses suggested an enrichment of the cholesterol biosynthetic process and an overrepresentation of categories related to “ion transmembrane transport” in the camel kidney, and RTN analyses confirmed alterations in the transcriptional machinery involved in cholesterol synthesis. These data were validated by RT-qPCR. Based on our hypothesis of a role for cholesterol during dehydration, we identified DEGs with roles in the countercurrent multiplication process which are affected by changes in the level of cholesterol. Thus, we further validated 3 genes coding for ion transporting proteins (KCNJ8, SLC9A7 and ATP1B3) and AQP2, which were upregulated during dehydration. Our datasets suggest that suppression of cholesterol biosynthesis may facilitate water retention in the kidney of the dromedary by indirectly enhancing the osmotic gradient along the medullary interstitium and the AQP2-mediated water reabsorption.
