The goal of this study is to elucidate the influence of treadmill training on transcriptome of the upper lumbar spinal cord after thoracic spinal cord hemisection. mRNA profiles of spinal cords at 23 days-post injury with/without treadmill training were generated. The expression levels of 650 genes in the trained animal were increased ( > 2-fold) compared to untrained animals. Our study represents the detailed analysis of transcriptomes of spinal cord distal to the hemisected lesion after treadmill training, with biologic replicates, generated by RNA-seq technology. Overall design: The effect of training after spinal cord injury (T9) on the transcriptome of intact upper spinal cord was investigated.

View SamplesWe collected globular stage seed compartments from 5 or 7-micron paraffin sections using the Leica LMD6000 system in order to identify the mRNAs present in different compartments of an Arabidopsis seed containing a globular stage embryo. For the purposes of this study we broke down the seed into 8 capturable compartments: embyro proper, suspensor, micropylar endosperm, peripheral endosperm, chalazal endosperm, chalazal seed coat, general seed coat, and whole seeds.

View SamplesWe collected heart stage seed compartments from 7 micron paraffin sections using the Leica LMD6000 system in order to identify the mRNAs present in different compartments from seeds containing heart stage embryos. For the purposes of this study we captured 6 compartments: embryo proper, micropylar endosperm, peripheral endosperm, chalazal endosperm, chalazal seed coat and seed coat, as well sets of serial sections encompassing the entire heart stage seed.

For the purposes of this study we captured 6 compartments: embyro proper, micropylar endosperm, peripheral endosperm, chalazal endosperm, chalazal seed coat and general seed coat. Serial sections of entire seeds were also captured for comparison.

View SamplesBackground & Aims. Resection of hepatocellular carcinoma (HCC) tumors by partial hepatectomy (PHx) is associated with promoting hepatocarcinogenesis. We have previously reported that PHx promotes hepatocarcinogenesis in the Mdr2-knockout (Mdr2-KO) mouse, a model for inflammation-mediated HCC. Now, we explored the molecular mechanisms underlying the tumor-promoting effect of PHx in these mice. Methods. Using microarrays-based techniques, we compared genomic and transcriptomic profiles of HCC tumors developing in the Mdr2-KO mice either spontaneously or following PHx. Results. PHx accelerated HCC development in these mice by four months. PHx-induced tumors had only amplifications affecting multiple chromosomes and locating mainly near the acrocentric centromeres of murine chromosomes. Four different chromosomal regions were amplified each in at least three tumors. All tumors of untreated mice had chromosomal aberrations, including both deletions and amplifications. Comparison of gene expression profiles revealed a significantly enriched expression of oncogenes, chromosomal instability markers and E2F1 targets in the post-PHx compared to spontaneous tumors. Both tumor groups shared the same frequent amplification at chromosome 18. Here, we demonstrated that one of the regulatory genes encoded by this amplified region, Crem, was over-expressed in the nuclei of murine and human HCC cells in vivo, and that it stimulated proliferation of human HCC cells in vitro. Conclusions: PHx of a chronically inflamed liver directed tumor development to a discrete pathway characterized by amplification of specific chromosomal regions and expression of specific tumor-promoting genes. Crem is a new candidate HCC oncogene frequently amplified in this model and frequently over-expressed in human HCC.
