Project description:Thermal condition is an important envrionment factor to produce healthy pig. A mineral heat ware, RAVI is a regenerative far-infrared heating system. The purpose of this sutyd was to evaluate immunostimulating effects in pigs when RAVI was applied to maintain thermal condition compared with gasoline heater.
Project description:This experiment broadens our understanding of the temporal dynamics underlying the transcriptional response to heat stress. Using C. elegans hermaphrodite N2 populations, we have created a high-resolution time series of gene expression profiles taken at different time points during prolonged heat stress (35 C) conditions. Samples ware taken after 0h, 0.5h, 1h, 2h, 3h, 4h, 6h, 8h, and 12h of heat exposure with 3-5 biological replicas per time point.
Project description:Decreased mineral density is a risk factor for skeletal pathologies including bone metastasis, the leading cause of mortality in patients with advanced breast cancer, but the underlying mechanisms are poorly understood. While reduced mineral density can drive pathological bone remodeling via direct effects on select cell types, indirect effects due to broad changes of the microenvironment may be similarly important. However, how bone mineral content affects microenvironmental heterogeneity remains to be elucidated. Here, we leverage decellularized bone matrices with varied mineral content in combination with single-cell RNA-sequencing to study how reduced bone mineral content affects microenvironmental complexity and tumor growth. We performed single-cell RNA sequencing on implanted decellularized bovine bone scaffolds in which the mineral was either maintained at physiological levels or removed to simulate scenarios of impaired bone mineralization as, for example, present during aging. Using this approach, we explored the heterogeneous stromal response to varied bone mineral content in both an immunocompromised and immunocompetent, syngeneic mouse model in the presence and absence of cancer cells.
Project description:Anoxia induces several heat shock proteins and a heat pre-treatment can acclimatize Arabidopsis seedlings to a subsequent anoxic treatment. In this work we analyzed the response of Arabidopsis seedlings to anoxia, heat and a combined heat+anoxia stress. A significant overlapping between the anoxic and heat shock responses has been observed by whole-genome microarray analysis.
Project description:We report the application of Illumina RNA sequencing for characterization and discovery of genes and transcripts in Italian Large Whtie pig backfat tissue. RNAs sequencing for long RNA quantification, discovery, characterisation and differential expression evaluation.
Project description:Miniature pig is a useful animal model to clarify the vital reaction and the molecular mechanisms. However, physiclogical response of pig model to sodium azide (AZIDE) stress is not reveal. To establishment of large animal model for evaluate toxic stress, whole blood of miniature pig were assessed with genomics.
Project description:Miniature pig is a useful animal model to clarify the vital reaction and the molecular mechanisms. However, physiclogical response of pig model to sodium azide (AZIDE) stress is not reveal. To establishment of large animal model for evaluate toxic stress, whole blood of miniature pig were assessed with genomics. 7 month old clawn miniature pigs were fed AZIDE feeding. AZIDE dose of 300µg/kg, one hundredth of LD50 was given orally to the miniature pigs. Whole blood gene expression was measured at 0h, 6h and 24h after feeding.
Project description:Genome integration-free pig induced pluripotent stem cells (iPSCs) bring tremendous value in preclinical testing of regenerative medicine, as well as conservation and exploitation of endangered or rare local pig idioplasmatic resources. However, due to a lack of appropriate culture medium, efficient induction and stable maintenance of pig iPSCs with practical value remains challenging. Here, we established an efficient induction system for exogenous gene-independent iPSCs under WNT-inhibited condition previously used for generation of stable pig pre-gastrulation epiblast stem cell lines (pgEpiSCs). WNT suppression was found to play an essential role in establishment of exogenous gene-independent iPSCs. Strikingly, stable integration-free pig iPSCs could be reprogrammed from pig somatic cells using episomal vectors in this cultured condition. The iPSCs had pluripotency features and transcriptome characteristics approximating pgEpiSCs. More importantly, this induction system may be used to generate integration-free iPSCs from elderly disabled rare local pig somatic cells, and the iPSCs could be gene-edited and used as donor cells for nuclear transfer. Our results provide novel insights into potential applications for genetic breeding of livestock species and pre-clinical evaluation of regenerative medicine.
Project description:Shochu distilled water (SDW) was used as a feedstuff for livestock. We have tried to evaluate the physiology of pig during feeding SDW using genomics.
