Project description:As a historical nomadic group in Central Asia, Kazaks have mainly inhabited the steppe zone from the Altay Mountains in the East to the Caspian Sea in the West. Fine scale characterization of the genetic profile and population structure of Kazaks would be invaluable for understanding their population history and modeling prehistoric human expansions across the Eurasian steppes. With this mind, we characterized the maternal lineages of 200 Kazaks from Jetisuu at mitochondrial genome level. Our results reveal that Jetisuu Kazaks have unique mtDNA haplotypes including those belonging to the basal branches of both West Eurasian (R0, H, HV) and East Eurasian (A, B, C, D) lineages. The great diversity observed in their maternal lineages may reflect pivotal geographic location of Kazaks in Eurasia and implies a complex population history. Comparative analyses of mitochondrial genomes of human populations in Central Eurasia reveal a common maternal genetic ancestry for Turko-Mongolian speakers and their expansion being responsible for the presence of East Eurasian maternal lineages in Central Eurasia. In addition, our analyses indicate maternal genetic affinity between the Sherpas from the Tibetan Plateau with the Turko-Mongolian speakers.
Project description:We conducted transcriptome analysis of Komagataeibacter europaeus CGMCC 20445 samples under different acidity conditions to elucidate the changes in differentially expressed genes throughout the fermentation process.
Project description:We genotyped 322 new samples from 38 Eurasian populations and combined it with previously published data to characterize the population structure of Turkic-speaking populations in the context of their geographic neighbors across Eurasia
Project description:In order to establish a profile of tumour vascular expression which could potentially be targeted therapeutically, we performed agilient microarray analysis on 4 samples each or renal cell carcinoma, colorectal cancer, colorectal metastasis to the liver and matched healthy tissues. The tumours had recieved no treatement prior to resection. The expression profiles were compared by one colour microarray analysis between matched healthy and tumour tissue. Genes expressed in all/or most of the comparisons were taken forward for further analysis. See acompanying publication: Wragg JW, Finnity JP, Anderson JA, Ferguson HJM, Bhatt RI, Murray PG, Heath VL, Bicknell R. MCAM is a vascular target in renal cancer. Cancer Research. 2016. The endothelum was isolated using collagenase V digestion, and dynabead magnetic bead isolation conjugated to lectin from Ulex Europaeus (Ulex Europaeus Agglutinin I (UEA I)), which binds human endothelial cells.
