Complex regulatory mechanisms underlying mineral nutrient acquisition in soybean roots responsive to low pH stress

Project description:Proton toxicity is one of the major environmental stresses limiting crop production, and becomes increasingly serious because of anthropogenic activities. To understand acid tolerance mechanisms, the plant growth, mineral nutrient accumulation and global transcriptome changes in soybean (Glycine max) in response to long-term acid stress were investigated. Results showed that acid stress significantly inhibited soybean root growth, but exhibited slight effects on the shoot growth. Moreover, concentrations of essential mineral nutrients were significantly affected by acid stress, mainly dependent on soybean organs and mineral nutrient types. The concentrations of phosphorus (P) and molybdenum (Mo) in both leaves and roots, nitrogen (N) and potassium (K) in roots and magnesium (Mg) in leaves were significantly decreased, respectively. Whereas, the concentrations of calcium (Ca), sulfate (S) and iron (Fe) were increased in both leaves and roots. Transcriptome analyses in soybean roots resulted in identifying 419 up-regulated and 555 down-regulated genes under acid conditions. A total of 38 differentially expressed genes (DEGs) were involved in mineral nutrient transportation. Among them, all the detected five GmPTs and GmZIPs, two GmAMTs and GmKUP genes, together with GmIRT1, GmNramp5, GmVIT2.1, GmSKOR, GmTPK5 and GmHKT1, were significantly suppressed. Moreover, the genes encoding transcription factors (e.g., GmSTOP2s and a GmPHL1), and genes involved in pH stat metabolic pathways were significantly up-regulated by low pH stress in soybean roots. Taken together, it strongly suggested that maintaining pH stat and mineral nutrient homeostasis are adaptive strategies of soybean responses to acid stress, which might be regulated by a complex signaling network.

Mapping the tumor microenvironment response to bone mineral content

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.

Chronic mineral oil administration increased hepatic inflammation in wild type mice compared to lipocalin 2 null mice

Project description:Concerning the roles of LCN2 in chronic inflammation and fibrosis, we investigated chronic liver inflammation and fibrosis using repeated carbon tetrachloride (CCl4) in mineral oil injection. We found that mice treated with the mineral oil vehicle alone also showed liver inflammation and more severe in wild-type mice compared to lipocalin 2 null mice.

Evaluation of immunostimulating effects of mineral heat ware in pig

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.
