Urokinase-type plasminogen activator (uPA) and c-met play a major role in cancer invasion and metastasis. Evidence has suggested that uPA and c-met overexpression may be coordinated in human hepatocellular carcinoma (HCC). In the present study, to understand whether the expression of these genes might be coregulated by specific microRNAs (miRs) in human(More)
BACKGROUND Cardiovascular malformations have a higher incidence in patients with NF1 microdeletion syndrome compared to NF1 patients with intragenic mutation, presumably owing to haploinsufficiency of one or more genes included in the deletion interval and involved in heart development. In order to identify which genes could be responsible for(More)
Noonan syndrome is a genetic condition characterized by congenital heart defects, short stature, and characteristic facial features. Familial or de novo mutations in PTPN11, RAF1, SOS1, KRAS, and NRAS are responsible for 60-75% of the cases, thus, additional genes are expected to be involved in the pathogenesis. In addition, the genotype-phenotype(More)
CDK5R1 encodes p35, a specific activator of the serine/threonine kinase CDK5, which plays crucial roles in CNS development and maintenance. CDK5 activity strongly depends on p35 levels and p35/CDK5 misregulation is deleterious for correct CNS function, suggesting that a tightly controlled regulation of CDK5R1 expression is needed for proper CDK5 activity.(More)
CDK5R1 plays a central role in neuronal migration and differentiation during central nervous system development. CDK5R1 has been implicated in neurodegenerative disorders and proposed as a candidate gene for mental retardation. The remarkable size of CDK5R1 3'-untranslated region (3'-UTR) suggests a role in post-transcriptional regulation of CDK5R1(More)
Cyclin-dependent kinase 5 regulatory subunit 1 (CDK5R1) encodes p35, a specific activator of cyclin-dependent kinase 5 (CDK5). CDK5 and p35 have a fundamental role in neuronal migration and differentiation during CNS development. Both the CDK5R1 3'-UTR's remarkable size and its conservation during evolution strongly indicate an important role in(More)
Mental retardation (MR) is displayed by 57% of NF1 patients with microdeletion syndrome as a result of 17q11.2 region haploinsufficiency. We considered the cyclin-dependent kinase 5 regulatory subunit 1 (CDK5R1) and oligodendrocyte-myelin glycoprotein (OMG) genes, mapping in the NF1 microdeleted region, as candidate genes for MR susceptibility. CDK5R1(More)
Cyclin-dependent kinase 5 regulatory subunit 1 (CDK5R1) encodes p35, the main activatory subunit of cyclin-dependent kinase 5 (CDK5). The p35/CDK5 active complex plays a fundamental role in brain development and functioning, but its deregulated activity has also been implicated in various neurodegenerative disorders, including Alzheimer’s disease (AD).(More)
In this report, we describe two adult brothers affected by moderate non-specific intellectual disability (ID). They showed minor facial anomalies, not clearly ascribable to any specific syndromic patterns, microcephaly, brachydactyly and broad toes. Both brothers presented seizures. Karyotype, subtelomeric and FMR1 analysis were normal in both cases. We(More)
