Affymetrix Mouse Genome 430 2.0 Array (mouse4302)
Description
In contrast to the migration of leukocytes from blood vessels into tissues, and the involvement of adhesion molecules and chemokines in this process, the migration of leukocytes from the tissue into lymphatic vessels is much less well understood. This can, in part be explained by the fact that murine lymphatic endothelial cells (LECs) have proven particularly hard to isolate and propagate in culture. Hence, it has been difficult to establish suitable models to study this process in vitro. Combining magnetic bead-based purification and fluorescence-activated cell sorting (FACS), we have isolated LECs (immorto-LECs) from the skin of mice which express a temperature-sensitive SV40 large T antigen (H-2Kb-tsA58 mice; ImmortoMice) in all cell types under the control of the MHC-class-I-promotor, H-2Kb. The isolated cells are viable for more than 30 passages when cultured at 33 C, the temperature at which the large T antigen is stably expressed. Furthermore, immorto-LECs tolerate several days of culture at 37 C, but become senescent if continuously cultured at this temperature. All cells stably express endothelial and lymphatic markers like CD31, podoplanin, Prox-1 and VEGFR-3 up to passage 30. When cultured in presence of tumor necrosis factor-alpha (TNF-a), immorto-LECs upregulate adhesion molecules, such as ICAM-1, VCAM-1 and E-selectin, similarly to what has been reported to occur under inflammatory conditions in vivo. Overall, our findings establish immorto-LECs as a useful and handy tool for the in vitro investigation of immune cell transmigration across lymphatic endothelium.

Description
ALS is a uniformly fatal neurodegenerative disease in which motor neurons in the spinal cord and brain stem are selectively lost. Individual motor - groups of motor neurons innervating single muscles - show widely varying degrees of disease resistance: in the final stages of ALS, nearly all voluntary movement is lost but eye movement and eliminative and sexual functions remain relatively unimpaired. These functions are controlled by motor neurons of the oculomotor (III), trochlear (IV) and abducens (VI) nuclei in the midbrain and brainstem, and by Onufs nucleus in the lumbosacral spinal cord, respectively. Correspondingly, in ALS autopsies the oculomotor and Onufs nuclei are almost completely preserved. We used microarray profiling of isolated wildtype mouse motor neurons to identify genes whose expression was characteristic of both oculomotor and Onufs nuclei but not of vulnerable lumbar spinal neurons, or vice versa.

Description
Snf1 and TORC1 are two global regulators that sense the nutrient availability and regulate the cell growth in yeast Saccharomyces cerevisiae. Here we undertook a systems biology approach to study the effect of deletion of these genes and investigate the interaction between Snf1 and TORC1 in regulation of gene expression and cell metabolism.

Description
In animals, microRNAs frequently form families with related sequences. The functional relevance of miRNA families and the relative contribution of family members to target repression have remained, however, largely unexplored. Here, we used the C. elegans miR-58 miRNA family, comprised primarily of four highly abundant members: miR-58.1, miR-80, miR-81 and miR-82, as a model to investigate the redundancy of miRNA family members and their impact on target expression in an in vivo setting. Overall design: RNA was extracted from different miR-58 family mutants (mir-58.1, mir-80; mir-58.1 and mir-80; mir-58.1; mir-81-82) and wild-type Bristol C. elegans strain at late L4 stage and submitted to transcriptome sequencing with Illumina HiSeq2000. The goal was to compare miR-58 target RNA expression and system-wide perturbations across various samples.
