Project description:Protein abundance changes and reversible protein phosphorylation (RPP) play important roles in regulating hypometabolism but have never been documented in overwintering frogs at high altitudes. To test the hypothesis that protein abundance and protein phosphorylation change in response to winter hibernation, we conducted a comprehensive and quantitative proteomic and phosphoproteomic analysis of the liver of the Xizang plateau frog, Nanorana parkeri, living on the Qinghai-Tibet Plateau.

The microbial functional diversity in response to altered precipitation on Tibet Plateau as characterized by GeoChip

Project description:Global warming substantially changes precipitation patterns in the Tibetan plateau, with projection of increased precipitation in southern and northern Tibet but decreased precipitation in the center. Understanding mechanisms of such changes in greenhouse gas emissions is of vital importance in predicting ecosystem feedbacks to climate changes. Nonetheless, it has been hampered by limited knowledge in soil microbial communities, one of the major drivers of greenhouse gas emission. Here, we report a field experiment simulating drying and wetting conditions in the Tibetan grassland. Our field site is located at the Haibei Alpine Grassland Ecosystem Research Station in the northeast of Tibet Plateau, China, and we employed GeoChip 5.0 180K to analyze microbial responses.

Gene Expression Profiling of High Altitude Polycythemia in Han Chinese migrated to Qinghai-Tibetan Plateau

Project description:Long term-exposed to high altitude, the increased numbers of red blood cells tend to stabilize to a certain extend in most people, but someone will occur over-increasing in number of red blood cells, which cause a serious of clinical symptoms and signs, and this is high altitude polycythemia. EPO-EPOR system may be the main reasons for erythroid progenitor cell proliferation and differentiation in early exposion to plateau, but, in the late, there may be other factors involved in the regulation of erythropoiesis in bone marrow, multiple factors working together lead to excessive red blood cell proliferation. We compared gene expression profiling of leukocytes in peripheral blood from high altitude polycythemia patients with those from matched controls. Subjects consisting of 5 masculine Han Chinese patients with HAPC (diagnosed according to international consensus statement on HAPC) and 5 matched controls, were migrants at River of TUOTUO area (Qinghai-Tibetan Plateau, 4550 m). Each of the five HAPC patients was matched to each of the control: gender, nationality, birthplace, duration migrating to plateau, height of location, work intensity. Peripheral blood samples were obtained at 4550m plateau from above subjects. Total RNA was extracted from peripheral blood leucocytes. The gene expression profilings were analysed by Human Genome U133 Plus 2.0 Array.
