Project description:Embryonic stem cells (ESCs) have the ability to differentiate into cells of the three germ layers, and leukemia inhibitory factor (LIF) maintains the pluripotency and promotes the proliferation of ESCs. In the absence of LIF, ESCs spontaneously differentiate and form three-dimensional aggregates known as embryoid bodies (EBs). The differentiation of EBs mimics the process of embryonic development, that is, the differentiation of cells into the three embryonic germ layers (endoderm, mesoderm, and ectoderm), some of which differentiate into beating cardiomyocytes. Static magnetic fields have diverse effects on organisms, studies on the regulation of the differentiation of ESCs to cardiomyocytes by static magnetic fields are not sufficient. To better understand transcriptional landscape and signal transductions, we performed RNA-seq analysis of EBs cultured in two different conditions: conventional incubator, static magnetic field incubator.

Project description:Purpose:Next Generation Sequencing applying for compare the CD8+ T cells with 0.3T static magnetic field (SMF) or not transcriptome, included pathway-enrichment analysis and genes expression of interests Methods:CD8+ T cells were isolated from splenocytes in 8 week old wild type mice through STEMCELL Technologies negative selection kit. FACS sort CD8+ T cells after 3 days with CD3/CD28 costimulation at 0.3T static magnetic field or not. RNA was extracted, purified and checked for integrity using an Agilent Bioanalyzer 2100. Libraries were generated for sequencing using the SMARTer Stranded Total RNA-Seq Kit - Pico Input Mammalian. Libraries were sequenced using an Illumina HiSeq X Ten sequencer. Resluts: Using an optimized data analysis workflow, we mapped about 30 million sequence reads per sample to further analyse Conclusions:Our study represents the detailed analysis of CD8+ T cells with 0.3T static magnetic field or not transcriptomes

Project description:Neural proliferation and differentiation fates of pluripotent stem cells are influenced by external natural forces. Despite the presence of biogenic magnetite nanoparticles in the central nervous system and constant exposure to Earth’s magnetic fields and other sources, there has been scant knowledge regarding the role of electromagnetic stimuli in neurogenesis. Moreover, the emerging application of electrical and magnetic stimulation to treat neurological disorders emphasizes the relevance of understanding the impact and mechanisms behind these stimuli. Here, the effects of magnetic nanoparticles (MNPs) contained in polymeric coatings and the static external magnetic field (EMF, 0.4 Tesla) were investigated on neural induction of murine embryonic stem cells (mESCs) and human induced pluripotent stem cells (hiPSCs) into induced dopaminergic neurons (iDA).

Project description:Vaccinia virus-related kinase (VRK) is an evolutionarily conserved nuclear protein kinase. VRK-1, the single Caenorhabditis elegans VRK ortholog, functions in cell division and germline proliferation. However, the role of VRK-1 in post-mitotic cells and adult lifespan remain unknown. Here, we show that VRK-1 increases organismal longevity by activating the cellular energy sensor, AMP-activated protein kinase (AMPK), via direct phosphorylation. We found that overexpression of vrk-1 in the soma of adult C. elegans increased lifespan, and conversely, inhibition of vrk-1 decreased lifespan. In addition, vrk-1 was required for longevity conferred by mutations that inhibit C. elegans mitochondrial respiration, which requires AMPK. Notably, VRK-1 directly phosphorylated and up-regulated AMPK in both C. elegans and cultured human cells. Thus, our data show that the somatic nuclear kinase, VRK-1, promotes longevity through AMPK activation, and this function appears to be conserved between C. elegans and humans.
