Project description:For individuals migrating to or residing permanently at high-altitude regions, environmental hypobaric hypoxia is a primary challenge which induces several physiological or pathological responses. It is well documented that human beings adapt to hypobaric hypoxia via some protective mechanisms, such as erythropoiesis and overproduction of hemoglobin, however little is known on the changes of plasma proteome profiles in accommodation to high-altitude hypobaric hypoxia. In the present study, we investigated differential plasma proteomes of high altitude natives and lowland normal controls by a TMT-based proteomic approach. A total of 818 proteins were identified, of which 137 were differentially altered. Bioinformatics (including GO, KEGG, protein-protein interactions, etc.) analysis revealed the dysregulated proteins were primarily involved in complement and coagulation cascades, anti-oxidative stress and glycolysis. Validations via magnetic Luminex® Assays and ELISA demonstrated that CCL18, C9, PF4, MPO and S100A9 notably up-regulated, and HRG and F11 down-regulated in high altitude natives compared with lowland controls, which were consistent with the proteomic results. Our findings highlight the roles of complement and coagulation cascades, anti-oxidative stress and glycolysis in acclimatization to hypobaric hypoxia and provide a foundation for developing potential diagnostic or/and therapeutic biomarkers for high altitude hypobaric hypoxia-induced diseases.

Project description:Purpose: High-altitude adaptive evolution of transcription, and the convergence and divergence of transcriptional alteration across species in response to high-altitude environments, is an important topic of broad interest to the general biology community. Our study aims to answer this important biological question. Methods: We generated deep transcriptome data of high- and low- altitude populations across four species: chicken, pig, goat and sheep, as well as high-altitude yak and low-altitude cattle, from six tissues (heart, kidney, liver, lung, skeletal muscle and spleen). Results: Here we provide a comprehensive comparative transcriptome landscape of expression and alternative splicing variation between low- and high-altitude populations across multiple species for distinct tissues. Conclusions: Our data serves a valuable resource for further study on adaptive transcription evolution and identification of candidate adaptive genes.

Project description:This study evaluates genetic and phenotypic variation in the high altitude Colla population living in the Argentinean Andes above 3500 m. They were compared to the Wichà population living in the nearby lowlands of the Gran Chaco region. This study attempts to pinpoint evolutionary mechanisms underlying adaptation to hypobaric hypoxia. We have genotyped 25 individuals from both populations for 730,525 SNPs. DNA from 25 saliva samples from Collas living >3500 m and 25 saliva samples from Wichà living <500 m from the Province of Salta in Argentina was genotyped

Project description:Understanding molecular mechanism associated with high altitude exposure during acclimatization/adaptation/maladaptation. Data reveals specific components of the complex molecular circuitry underlying high altitude pulmonary edema. Individualized outcome prediction were constructed through expression profiling of 39400 genes in sea level sojourners who were acclimatized to high altitude and grouped as controls (n=14), high altitude natives (n=14) and individuals who developed high altitude pulmonary edema within 48-72 hours after air induction to high altitude (n=17).

Project description:Purpose: Domestic goats distributed in a wide range of habitats and have evolved genetic adaptations to their local environmental conditions. The goal of this study s to investigate the dramatic gene expression changes of goats that are shaped by high altitude adaptation. Methods: We performed RNA-seq on 27 samples from the three hypoxia-sensitive tissues (heart, lung and skeletal muscle) in three indigenous populations residing in distinct altitudes (600 m, 2,000 m and 3,000 m). Results: We identified numerous differentially expressed genes which exhibited distinct expression patterns, and nonsynonymous SNVs-containing genes which highly differentiated between the high- and low-altitude populations. Conclusions: These identified genes have known or potential roles in hypoxia response, and enriched in functional gene categories potentially responsible for high altitude adaptation, are appealing candidates for further investigation of the adaptive evolution in harsh high-altitude environment.

Project description:High-altitude adaptation is a representative example of vertebrates getting adapted to harsh and extreme environments. To investigate the miRNA expression alterations of goats that were induced by high altitude stress, we performed comparative miRNA transcriptome analysis on six hypoxia-sensitive tissues (heart, kidney, liver, lung, skeletal muscle and spleen) in two indigenous goat populations from distinct altitudes (600 m and 3000 m). We obtained the expression of 1391 mature miRNAs and identified 138 differentially expressed miRNAs between altitudes. Combined with tissue specificity analysis, we illustrated alterations of expression levels between altitudes and among tissues, which suggested the coexisting tissue-specific and tissue-conserved mechanism for hypoxia adaptation. Notably, the interplay between DE miRNA and DE target genes strongly indicated post-transcriptional regulation in HIF-1 signaling pathway, insulin signaling pathway and p53 signaling pathway, which might play a significant role in high altitude adaptation in domestic goats. These results provide insights into the complicated miRNA expression pattern and regulatory mechanism of high altitude adaptation in domestic goats.
