Description
Psychological, psychosocial and physical stress are major risk factors, which enhance the development of sporadic late-onset Alzheimer`s disease. The chronic unpredictable mild stress model mimics those risk factors and triggers signs of neurodegeneration and neuropathological features of sporadic AD such as tau hyperphosphorylation and enhanced amyloid beta generation. The study investigated the impact of chronic unpredictable mild stress on signs of neurodegeneration by analyzing hippocampal gene expression with whole genome microarray gene expression profiling.

Description
ASCL1 is a master transcription factor for neuroendocrine differentiation. RNA-sequencing analysis on VMRC-LCD cells following ASCL1 knockdown revealed a subset of genes possibly regulated by ASCL1. Overall design: VMRC-LCD cells were transfected with siRNAs for ASCL1, and RNA-sequencing was performed using Illumina HiSeq.

Description
Somatic mutations in calreticulin (CALR) are present in approximately 40% of patients with myeloproliferative neoplasms (MPN). However, the mechanism by which mutant CALR is oncogenic is unknown. Here, we demonstrate that a megakaryocytic-specific MPN phenotype is induced when mutant CALR is over-expressed in mice and that the thrombopoietin receptor, MPL is required for mutant CALR driven transformation. Whole transcriptome analysis reveals enrichment of STAT signatures in mutant CALR transformed cells and JAK2 inhibitor treatment abrogates STAT activation. Employing extensive mutagenesis-based structure-function analysis we demonstrate that the positively charged amino acids within the mutant CALR C-terminus are required for cellular transformation through facilitating physical interaction between mutant CALR and MPL. Together, our findings elucidate a novel mechanism of cancer pathogenesis. Overall design: Transcriptomes derived from BA/F3-MPL cells transformed with human wild-type CALR, human mutant CALR 52bp del, or Empty vector, at time zero (t0) and 24 hours (t24) after IL3-withdrawal culture were generated by deep sequencing, two replicas, by HiSeq2000.

Description
To explore the degree to which the glioma cell lines remained transcriptionally stable under diverse experimental conditions, we transplanted three different lines (U3020MG, U3047MG and U3065MG) intracranially to NOD-SCID mice; explanted the resulting tumors and cultured the cells for two passages, and then isolated RNA from the cell line prior to transplantation (U3020MG-p10, U3047MG-p7, U3065MG-p10), from the xenograft tumor and from the explanted cells.
