CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe transcriptome of the CD34+ cells was determined in a group of 10 patients with the 5q- syndrome using a comprehensive array platform, and was compared with the transcriptome of CD34+ cells from 16 healthy control subjects and 14 patients with refractory anaemia and a normal karyotype. The majority of the genes assigned to the commonly deleted region (CDR) of the 5q- syndrome at 5q31-q32 showed a reduction in expression levels in patients with the 5q- syndrome, consistent with the loss of one allele. Candidate genes showing haploinsufficiency in the 5q- syndrome included the tumour suppressor gene SPARC and RPS14, a component of the 40S ribosomal subunit. Two genes mapping to the CDR, RBM22 and CSNK1A1, showed a >50% reduction in gene expression, consistent with the downregulation of the remaining allele. This study identified several significantly deregulated gene pathways in patients with the 5q- syndrome and gene pathway analysis data supports the proposal that SPARC may play a role in the pathogenesis of the 5q- syndrome. This study suggests that several of the genes mapping to the CDR of the 5q- syndrome play a role in the pathogenesis of this disorder.

| Abstract: | The transcriptome of the CD34+ cells was determined in a group of 10 patients with the 5q- syndrome using a comprehensive array platform, and was compared with the transcriptome of CD34+ cells from 16 healthy control subjects and 14 patients with refractory anaemia and a normal karyotype. The majority of the genes assigned to the commonly deleted region (CDR) of the 5q- syndrome at 5q31-q32 showed a reduction in expression levels in patients with the 5q- syndrome, consistent with the loss of one allele. Candidate genes showing haploinsufficiency in the 5q- syndrome included the tumour suppressor gene SPARC and RPS14, a component of the 40S ribosomal subunit. Two genes mapping to the CDR, RBM22 and CSNK1A1, showed a >50% reduction in gene expression, consistent with the downregulation of the remaining allele. This study identified several significantly deregulated gene pathways in patients with the 5q- syndrome and gene pathway analysis data supports the proposal that SPARC may play a role in the pathogenesis of the 5q- syndrome. This study suggests that several of the genes mapping to the CDR of the 5q- syndrome play a role in the pathogenesis of this disorder. | |
