Molecular phenotype of MYCN non-amplified stage 4S neuroblastoma
ORGANISM(S): Homo sapiens 
Mutations in the tumor suppressor gene PTCH1 are responsible for Gorlin syndrome, or nevoid basal cell carcinoma syndrome (NBCCS). NBCCS causes predisposition to basal cell carcinoma (BCC), the commonest cancer in adult human. In the general population BCC develop almost exclusively in sun-exposed a...

Characterize the genes regulated by MKL1/SRF complex in human megakaryocytes (MKs) derived from cord blood or cytapheresis : Using a knock down approach by small interference of MKL1 in MK progenitors, we observed a decrease in the percentage of cells with actin polymerization after adhesion on vari...

The amounts of eIF4G and eIF4B were decreased in the vemurafenib-treated sensitive A375 cell line. To find mechanisms behind this decrease, we sought to identify the genes whose expression changes after vemurafenib treatment in A375 cells as compared to Mel624 cells by using microarrays.

The aim of the experiment was to characterize by a pan-genomic approach genes which are continuously up and down regulated during polyploidization during megakaryocyte differentiation.

Background New approaches are needed to improve prognostic accuracy for treatment response and to explore the complexities of drug effects on human tumours. We developed a strategy of global genomic investigation of sequential tumor biopsies at baseline and 21 days post-treatment, and applied this ...

A recent study of the characteristics of coexisting melanoma and renal cell carcinoma RCC in the same patients supports a genetic predisposition underlying the association between these two cancers. The microphthalmia associated transcription factor (MITF) was proposed to act as a melanoma oncogene;...

We have established a neuroblastoma model resistant in vivo to the topoisomerase I inhibitor irinotecan (CPT-11, Camptothecin-11, CAMPTOSAR®) in order to study resistance to these agents acquired in a therapeutic setting. Common mechanisms of resistance were not involved in this model and we thus ex...
