ChIP-seq data from pika Epas1 knock in MAF and RNA-seq data from mouse, rat, rabbit and Tibetan pika fibroblasts

Project description:MAF from pika Epas1-3FLAG knock-in mice were extracted and immortalized. After 12h DMOG treatment, cells were conducted for the ChIP-seq (Bmal1,Flag). We found that in knock-in mice fibroblasts, EPAS1-3FLAG can bind to similar E-box locus compared with BMAL1. Fibroblasts from mouse, rat, rabbit and Tibetan pika were extracted (and Tibetan pika fibroblasts were immortalized). RNA was extracted at 90% confluency. We found that Per2 mRNA level was significantly lower in Tibetan pika fibroblasts compared with other species.

Bovine granulosa cells of dominant follicles; comparison of plateau vs atretic

Project description:Granulosa cells originating from two different phases of antral follicle growth (plateau and atretic) were compared in follicles with a diameter of 9mm or more. The plateau follicle is the reference. Two conditions experiment (Plateau and Atretic); Four biological replicates for each group; Two technical replicates per samples (dye-swap).

Dairying supported prehistoric occupation of the highland Tibetan Plateau

Project description:The extreme environments of the Tibetan Plateau offer significant challenges to human survival, demanding novel adaptations. While the role of biological and agricultural adaptations in enabling early human colonization of the plateau has been widely discussed, the contribution of pastoralism is less well understood, especially the dairy pastoralism that has historically been central to Tibetan diets. Here, we analyze preserved proteins from the dental calculus of 40 ancient individuals to report the earliest direct evidence of dairy consumption on the Tibetan Plateau. Our palaeoproteomic results demonstrate that dairy pastoralism began on the higher plateau by approximately 3,500 years ago, more than 2,000 years earlier than the recording of dairying in historical sources. With less than 1% of the Tibetan Plateau dedicated to farmland, pastoralism and the milking of ruminants were essential for large-scale human expansion into agriculturally-marginal regions that make up the majority of the plateau. Dairy pastoralism allowed conversion of abundant grasslands into nutritional human food, which facilitating adaptation in the face of extreme climatic and altitudinal pressures, and maximizing the land area available for long-term human occupation of the “roof of the world”.

Genetic diversity and sex-bias dispersal of plateau pika in Tibetan plateau.

Project description:Dispersal is an important aspect in organism's life history which could influence the rate and outcome of evolution of organism. Plateau pika is the keystone species in community of grasslands in Tibetan Plateau. In this study, we combine genetic and field data to character the population genetic pattern and dispersal dynamics in plateau pika (Ochotona curzoniae). Totally, 1,352 individual samples were collected, and 10 microsatellite loci were analyzed. Results revealed that plateau pika possessed high genetic diversity and inbreeding coefficient in a fine-scale population. Dispersal distance is short and restricted in about 20 m. An effective sex-biased dispersal strategy is employed by plateau pika: males disperse in breeding period for mating while females do it after reproduction for offspring and resource. Inbreeding avoiding was shown as the common driving force of dispersal, together with the other two factors, environment and resource. In addition, natal dispersal is female biased. More detailed genetic analyzes are needed to confirm the role of inbreeding avoidance and resource competition as ultimate cause of dispersal patterns in plateau pika.

Biogeographic conservation and CO2-dynamics of the cytosine methylome in the globally important cyanobacterium Trichodesmium [WGBS]

Project description:Our paper presents the results of a study in which we used whole genome bisulfite sequencing (WGBS), RNA-Seq (i.e. transcriptomics), high-CO2 physiology experiments, and spatiotemporally separated samples isolated in situ (i.e. directly from the ocean) to examine the metabolic potential of genome-wide cytosine (5mC) methylation (i.e. epigenomics), its potential impacts to transcriptional dynamics under both present-day and future ocean acidification conditions, and its biogeographic conservation in the globally-significant, biogeochemically-critical marine cyanobacterium Trichodesmium.
