Project description:Pod dehiscence is an important agronomic trait. Pod dehiscence would cause huge yield losses before soybean maturity. Although some of soybean pod dehiscence associated genes have been identified, the underlying mechanism of pod dehiscence is still not comprehensively explained. In this study, we have identified differentially expressed genes (DEGs) between shattering-resistant and shattering-susceptible soybean accessions based on transcriptome analyses of 10 soybean accessions. Long non-coding RNAs (lncRNAs) that may be involved in soybean pod dehiscence were also identified, and we constructed co-expression networks between mRNAs and lncRNAs. RNA sequencing results were further verified by real-time PCR. Furthermore, DEGs were screened through analyzing positions of soybean pod dehiscence quantitative trait locus (QTLs) and phenotypes of soybean pod dehiscence for achieving pod-dehiscence candidate genes.
Project description:Postoperative delirium (POD) is a common postoperative complication in elderly patients. The exact mechanism of POD is still unclear. In order to reveal the effect of CircRNA on POD, We analyzed the differential expression profile of circRNAs by microarray technique in hippocampus of 12-month-old mice between tibial fracture and control group.
Project description:Pod size varies among soybean cultivars, but the mechanism is largely unknown. We investigated pod size differences between two cultivars. The larger pod of ‘Tachinagaha’ was due to longer cell proliferation activity than in the shorter pod of ‘Iyodaizu’. Pod size of soybean 9 (GmPSS9), a member of the heat shock protein 70 family, was detected in a major QTL (qPSS on Chr. 2) as a candidate gene for determining pod length by QTL and expression QTL analysis. Expression of GmPSS9 in pods was higher in ‘Tachinagaha’ than in ‘Iyodaizu’ and was highest in early pod development. The difference in expression resulted from an indel polymorphism, Tachinagaha-specific-1, which has a 5′-UTR Py-rich stretch motif that boosts transcription. Treatment with an HSP70 inhibitor reduced plant height, pod length, and pod cell number. Our results identify GmPSS9 as a target gene for pod length which regulates cell number during early pod development.
Project description:Limited studies on comparison of developmental (neuro)toxicity of parabens have been conducted and unharmonized concentrations between phenotypic observations and transcriptomic analysis hamper understanding of their differential molecular mechanism. Developmental toxicity testing was conducted with commonly used methyl- (MtP), ethyl- (EtP) and propyl-paraben (PrP) in zebrafish embryos. Based on benchmark dose 5% (BMD5), embryonic mortality based-point of departure (M-PoD) values of three parabens were determined and changes in locomotor behavior were evaluated at concentrations of 0, M-PoD/50, M-PoD/10, and M-PoD in which transcriptomic analysis was conducted to explore the underlying neurotoxicity mechanism. Higher long-chained parabens were more toxic than short-chained parabens, as determined by M-PoD values of 154.1, 72.6, and 24.2 µM for MtP, EtP, and PrP, respectively. While exposure to EtP resulted in hyperactivity, no behavior effect was observed by MtP and PrP. Transcriptomics analysis revealed that abnormal behaviors in EtP-exposed group are associated with the distinctly enriched pathways in signal, transport, calcium ion binding, and metal-binding. In contrast, exposure to MtP and PrP mainly disrupted the membrane and transmembrane, which are closely linked to abnormal embryonic development rather than neurobehavior changes. According to the changes in expression of signature mRNAs, tentative transcriptomic-based PoD (T-PoD) values for each paraben were determined as MtP (2.68 µM), EtP (3.85 µM), and PrP (1.4 µM).
