Project description:Evaluation of gene expression changes corresponding to urogenital epithelial migration during early mouse prostatic development We used microarrays to investigate the global programme of gene expression in early mouse prostate tissue and identified necessary mediators of urogenital epithemial migration and relation to SOX9
Project description:DNA repair genes have been shown to be expressed in the early stages of mammalian development probably to reduce possible replication errors and genotoixc damages. Several birth defects and some cancers are due to inappropriate or defective DNA repair machinery indicating that a right activity of DNA repair genes in the early stages of fetal development are essential for an appropriate DNA function. Neuroblastoma (NB), an embryonal tumor deriving from neural crest cells (NCCs) is diagnosed in about 30% of patients within the first year of life. Moreover, several reports show that NB can be detected in foetus and in neonatal period. To assess gene expression profiling of DNA repair genes during early stage of development, we performed a genome-wide analysis of Neural Crest cells (NCCs) generating a gene expression database that can help to better understand the gene(s) involved in both genetic and cancer diseases. We found 11 genes involved in DNA repair activity during mouse embryo development overexpressed in early stages. Six out 11 were never been described in mouse embryology. Keywords: time course
Project description:Heparan sulfate (HS) is a linear, sulfated polysaccharide, and expresses abundantly in prostate and PCa tissues. Intriguingly, the HS content and sulfation modifications appear to increase when the prostate becomes malignance, suggesting that HS may critically modulate PCa pathogenesis. We specifically ablated Ext1, the enzyme that initiates HS biosynthesis, in mouse prostate at late development stage. And used microarray to detail the gene expressions affected by Ext1 ablation and identified distinct classes of up-regulated genes during this process.
