Description
In order to identify biologically relevant tumor markers, and novel therapeutic target we have compared the tumor gene expression profiles of long (OS>=24 months,n=14) and short (OS <=7months, n=11) survival patients. Then we conducted Kaplan-Meier survival analysis using all the 50 samples listed here. The Affymetrix gene-expression data of these 50 samples were also included in the earlier submission by us as GEO accession number GSE62452.

Description
Bloom syndrome is a rare autosomal recessive genetic instability and cancer predisposition syndrome caused by loss of function mutations in the BLM RECQ helicase gene. To ask if some of the distinctive pathological features of Bloom syndrome might reflect altered gene expression, we analyzed global mRNA and miRNA expression in fibroblasts from 16 patients and 15 matched normal controls, and in control primary diploid fibroblasts depleted of the BLM protein. We document significant differential expression of both protein-coding genes and miRNAs with well-characterized cancer associations in BLM-deficient cells. Differences in expression correlated significantly with G4 motifs, which are associated with potential to form G-quadruplex structures. These results indicate that BLM helicase may modulate gene expression by regulating the in vivo stability of G-quadruplex structures, and identify sets of genes and miRNAs whose expression, when altered, may drive the pathogenesis of Bloom syndrome and associated cancers.
Publication Title
Regulation of gene expression by the BLM helicase correlates with the presence of G-quadruplex DNA motifs.

Description
mRNA sequencing was used to identify genome wide transcriptional changes occuring in fly heads in response to spermidine feeding. This study shed light on the molecular mechanisms through wich spermidine can protect against age-dependent memory impairment. Overall design: mRNA profiles from 3 and 10 day old Drosophila melanogaster heads were generated in duplicate by deep sequencing using Illumina GAIIx. mRNA profiles from flies that were fed food with 5mM spermidine were compared to profiles from flies that had no spermidine in thier food.

Description
Maintenance and maturation of primordial germ cells is controlled by complex genetic and epigenetic cascades, and disturbances in this network lead to either infertility or malignant aberration. Transcription factor Tcfap2c / TFAP2C has been described to be essential for primordial germ cell maintenance and to be upregulated in several human germ cell cancers. Using global gene expression profiling, we identified genes deregulated upon loss of Tcfap2c in primordial germ cell-like cells. We show that loss of Tcfap2c affects many aspects of the genetic network regulating germ cell biology, such as downregulation maturation markers and induction of markers indicative of somatic differentiation, cell cycle, epigenetic remodeling, and pluripotency associated genes. Chromatin-immunoprecipitation analyses demonstrated binding of Tcfap2c to regulatory regions of deregulated genes (Sfrp1, Dmrt1, Nanos3, c-Kit, Cdk6, Cdkn1a, Fgf4, Klf4, Dnmt3b and Dnmt3l) suggesting that these genes are direct transcriptional targets of Tcfap2c in primordial germ cells. Since Tcfap2c deficient primordial germ cell like cells display cancer related deregulations in epigenetic remodeling, cell cycle and pluripotency control, the Tcfap2c-knockout allele was bred onto 129S2/Sv genetic background. There, mice heterozygous for Tcfap2c develop germ cell cancer with high incidence. Precursor lesions can be observed as early as E16.5 in developing testes displaying persisting expression of pluripotency markers. We further demonstrate, that mice with a heterozygous deletion of the Tcfap2c target gene Nanos3 are also prone to develop teratoma. These data highlight Tcfap2c as a critical and dose-sensitive regulator of germ cell fate.

Description
In order to identify biologically relevant tumor markers , we analyzed gene expression profiling of tumor and adjacent non-tumor tissues from PDAC cases. We compared the microarray gene-expression profiles of MIF-high and MIF low expressing tumors as detrmined by qRT-PCR. Affymetrix gene-expression analysis was done in two sets. Affymetrix data from sample number 1-90 were earlier submited by us as GEO accession#: GSE28735. The batch effect between the two sets of data was removed using Partek Genomic Suite and this normalized data was submitted to GEO in this submission. All the analysis was performed using the merged data set.
