Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
The premature aging disorder Werner Syndrome (WS) is characterized by early onset of aging phenotypes resembling natural aging. In most WS patients there are mutations in the DNA helicase WRN, an enzyme important in maintaining genome stability and telomere replication. Interestingly, its clinical manifestations reflect a severe degree of deterioration for connective tissue, whereas the central nervous system is less affected. We suggest that the varied vulnerability to aging is regulated by an unknown mechanism that protects specific lineages of stem cells from premature senescence. To address this problem, we reprogrammed patient skin fibroblasts to induced pluripotent stem cells (iPSC). The expression profile for the differentiated normal and WS fibroblasts and undifferentiated iPSC were compared. A distinct expression profile was found between normal and WS fibroblasts, however, few changes of gene expression were found in iPSC. Our findings suggest an erasure of aging phenotype associated with WS in reprogrammed iPSC.

Description
This experiment comprises 283 CEL files generated on the Affymetrix U133 Plus 2.0 gene expression microarray platform, using patient peripheral blood and bone marrow samples from the first cohort of patients accrued to Children's Oncology Group Study AALL0232. No clinical covariate data is provided at this time as the clinical study is not yet published. Researchers who would like to request outcome or other covariate data are asked to contact Dr. Cheryl Willman, cwillman@unm.edu, 505.272.5622 (University of New Mexico) and Dr. Steven Hunger, Stephen.Hunger@childrenscolorado.org (Children's Oncology Group and Children's Hospital Colorado) to arrange a collaboration.

Description
This Series represents the gene expression profiles of patients with multiple myeloma who have been treated previously. In brief, Total Therapy 6 (TT6) is an open label phase 2 protocol for patients with symptomatic multiple myeloma, who had been treated with more than one cycle of prior therapy excluding autologous hematopoietic stem cell transplant. This protocol was approved by the institutional review board on March 25, 2009 (IRB#108053). The TT6 treatment regimen consists of induction therapy with Melphalan/Bortezomib/Thalidomide/Dexamethasone/Cisplatin/Doxorubicin/Cyclophosphamide/Etoposide (M-VTD-PACE) followed by a high dose M-VTD-PACE based tandem transplant. Maintenance therapy consists of Bortezomib/Lenalidomide/Dexamethasone alternating with Borteomib/Melphalan/Dexamethasone every months for 3 years.

Description
Using the novel BTK inhibitor PF-303, we model the clinical phenotype of BTK inhibition by systematically examining the impact of PF-303 on the mature immune system in mice autoimmune indications. However, our current knowledge of the role of BTK in immune competence has been gathered in the context of genetic inactivation of btk in both mice and man. Using the novel BTK inhibitor PF-303, we model the clinical phenotype of BTK inhibition by systematically examining the impact of PF-303 on the mature immune system in mice. We implicate BTK in tonic BCR signaling, demonstrate dependence of the T3 B cell subset and IgM surface expression on BTK activity, and find that B1 cells survive and function independently of BTK. While BTK inhibition does not impact humoral memory survival, antigen-driven clonal expansion of memory B cells and antibody secreting cell generation are inhibited. These data define the role of BTK in the mature immune system and mechanistically predict the clinical phenotype of BTK inhibition.

Description
CHOPS syndrome is caused by germline gain-of-function mutations of AFF4. Cornelia de Lange syndrome is caused by germline mutations of cohesin loading factors or cohesin complex genes such as NIPBL, SMC1A, SMC3 and HDAC8. There are many overlapping clinical features exist between CHOPS syndrome and Cornelia de Lange syndrome. To identified commonly dysregulated genes in CHOPS syndrome and Cornelia de Lange syndrome, we perfomred side-by-side transcriptome comparison between CHOPS syndrome and Cornelia de Lange syndrome.

Description
AFF4 is a component of super elongation complex (SEC), which plays an important role in mobilizing paused RNA polymerase II at gene promoter regions. Using exome sequenging, we have identified a novel genetic disorder caused by missense mutations in AFF4. We propose CHOPS syndrome as a name for this new diagnosis. To evaluate the effect of identified missense mutations of AFF4, utilizing patient derived skin fibroblast cell lines, the gene expression analysis was perfomred.
