Transcription profiling of human hypothalamic hamartomas (HH) obtained from patients with or without precocious puberty (CPP)

ABSTRACT: Hypothalamic hamartomas (HHs) are congenital lesions of the neuroendocrine brain composed of neurons and astroglia. Frequently, HHs are associated with central precocious puberty (CPP) and/or gelastic seizures. Because HHs might express genes similar to those required for the initiation of normal puberty we used cDNA arrays to compare the gene expression profile of a HH associated with CPP with three HHs not accompanied by sexual precocity. Our aim was to identify genes whose expression may be selectively altered in the HH with CPP and hence, involved in the onset of puberty. Experiment Overall Design: Affymetrix arrays were used to detect global changes in gene expression. The results of this analysis were confirmed by semi-quantitative PCR.

Project description:At the molecular level, the mechanisms of action of Hox genes during hematopoiesis remain elusive. Although reports have described the implication of Hox genes in some molecular pathways in mice, the targets of HOX proteins in human hematopoietic cells are mostly unidentified. Since HOXB4 and HOXC4 are transcription factors encoded by paralogous genes that display similar effects on HSCs and progenitors, we presumed that HOXB4 and HOXC4 regulate the same target genes during human HSC expansion. This hypothesis was supported by the fact that HOXB4 and HOXC4 have similar molecular structure and similar roles and expression patterns during development. To identify early factors and signaling pathways involved in hematopoietic cell expansion consecutive to the action of HOXB4 or HOXC4, we performed a differential transcriptome analysis of RNAs from cord blood-derived CD34+ cells cultured for 24 hours in the presence of MS-5 cells engineered to secrete HOXB4 or HOXC4 proteins. MS-5/GFP cells were used as control in separate co-cultures to exclude nonspecific changes in gene expression that may be associated with the presence of lentivirus-transduced MS-5 cells. Human CD34+ cord blood (4.106) cells were co-cultured for 24 hours with irradiated EGFP-, HOXB4-, or HOXC4-transduced MS-5 cells. 12 arrays were analysed. Three competitive hybridizations to the arrays were performed in duplicate using each time two dye-swap following this experimental design: AVZ056 : CY5 (CD34+/MS5+HOXB4) / CY3 (CD34+/MS5+GFP) AVZ059 : CY5 (CD34+/MS5+GFP) / CY3 (CD34+/MS5+HOXB4) AVZ064 : CY5 (CD34+/MS5+GFP) / CY3 (CD34+/MS5+HOXB4) AVZ067 : CY5 (CD34+/MS5+HOXB4) / CY3 (CD34+/MS5+GFP) AVZ057 : CY5 (CD34+/MS5+GFP) / CY3 (CD34+/MS5+HOXC4) AVZ058 : CY5 (CD34+/MS5+HOXC4) / CY3 (CD34+/MS5+GFP) AVZ060 : CY5 (CD34+/MS5+HOXC4) / CY3 (CD34+/MS5+GFP) AVZ068 : CY5 (CD34+/MS5+GFP) / CY3 (CD34+/MS5+HOXC4) AVZ061 : CY5 (CD34+/MS5+HOXB4) / CY3 (CD34+/MS5+HOXC4) AVZ062 : CY5 (CD34+/MS5+HOXC4) / CY3 (CD34+/MS5+HOXB4) AVZ065 : CY5 (CD34+/MS5+HOXC4) / CY3 (CD34+/MS5+HOXB4) AVZ066 : CY5 (CD34+/MS5+HOXB4) / CY3 (CD34+/MS5+HOXC4)
