Gene expression between high and low altitude Mus musculus domesticus

ABSTRACT: Analysis of gene expression profiles is an attractive method for discovering how animals respond to environmental challenges in nature. Compared to low altitudes, high altitudes are characterized by reduced partial pressures of oxygen (hypoxia) and cooler ambient temperatures To better understand how mammals cope with high altitudes, we trapped wild house mice (Mus musculus domesticus) from 3 populations in La Paz, Bolivia (3000 - 3600 m) and 3 populations in Lima, Peru (0 – 200 m). Affymetrix GeneChip® Mouse Genome 430 2.0 Arrays were use to measure mRNA abundance in the livers of these mice.

Gene expression between high and low altitude Mus musculus domesticus

Project description:Analysis of gene expression profiles is an attractive method for discovering how animals respond to environmental challenges in nature. Compared to low altitudes, high altitudes are characterized by reduced partial pressures of oxygen (hypoxia) and cooler ambient temperatures To better understand how mammals cope with high altitudes, we trapped wild house mice (Mus musculus domesticus) from 3 populations in La Paz, Bolivia (3000 - 3600 m) and 3 populations in Lima, Peru (0 M-bM-^@M-^S 200 m). Affymetrix GeneChipM-BM-. Mouse Genome 430 2.0 Arrays were use to measure mRNA abundance in the livers of these mice. Eighteen male house mice were trapped from three different locations (3 mice per location)at high alttiude (La Paz, Bolivia, 3600 m) and from three locations at low altiditude (Lima, Peru, 100 m). Total mRNA was extracted from the livers and used for hybridization of Affymetrix GeneChip Mouse expression set 420.

miRNA expression in Placental Tissue from high altitude European and Tibetan women

Project description:We used in silico analyses to identify the distinct transcriptome signatures of two populations living at high altitudes and identified potential mechanisms that underlie high-altitude adaptation. Data generated in this study indicate that placentas from Tibetan women are genetically distinct from European women at high altitudes, and appear to be protected from hypoxia and stress.

Comparative microRNA Transcriptome in Domestic Goats Reveals Adaptation to High Altitude

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.

Transcriptomic analysis provides insights into the high-altitude adaptation in domestic goats

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.
