Deregulation of the tumour suppressor genes p14, p15, p16 and p53 in basal cell carcinoma
Background Basal cell carcinoma (BCC) is a locally aggressive slowly growing tumour that rarely metastasizes and is mostly seen in older members of the population. Objectives To determine the involvement of the tumour suppressor genes p14, p15, p16 and p53 in BCC. Methods We investigated the integrity of the CDKN2A locus in 15 BCC samples by analysing the presence of allelic imbalance ⁄ loss of...
متن کاملConspirators in a Capital Crime: Co-deletion of p18 and p16/p14/p15 in Glioblastoma Multiforme
Glioblastoma multiforme (GBM) is one of the most dreaded cancer diagnoses due to its poor prognosis and the limited treatment options. Homozygous deletion of the p16/ p14/p15 locus is among the most common genetic alterations in GBM. Two recent studies have shown that deletion and mutation of another INK4 family member, p18, also drives the pathogenesis of GBM. This minireview will discuss the ...
متن کاملLack of evidence for mutations or deletions in the CDKN2A/p16 and CDKN2B/p15 genes of Brazilian neuroblastoma patients.
Neuroblastoma, the most common extracranial tumor in childhood, has a wide spectrum of clinical and biological features. The loss of heterozygosity within the 9p21 region has been reported as a prognostic factor. Two tumor suppressor genes located in this region, the CDKN2B/p15 and CDKN2A/p16 (cyclin-dependent kinase inhibitors 2B and 2A, respectively) genes, play a critical role in cell cycle ...
متن کاملInfrequent methylation of CDKN2A(MTS1/p16) and rare mutation of both CDKN2A and CDKN2B(MTS2/p15) in primary astrocytic tumours.
In a series of 46 glioblastomas, 16 anaplastic astrocytomas and eight astrocytomas, all tumours retaining one or both alleles of CDKN2A (48 tumours) and CDKN2B (49 tumours) were subjected to sequence analysis (entire coding region and splice acceptor and donor sites). One glioblastoma with hemizygous deletion of CDKN2A showed a missense mutation in exon 2 (codon 83) that would result in the sub...
متن کاملCharacterization of a germ-line deletion, including the entire INK4/ARF locus, in a melanoma-neural system tumor family: identification of ANRIL, an antisense noncoding RNA whose expression coclusters with ARF.
We have previously detected a large germ-line deletion, which included the entire p15/CDKN2B-p16/CDKN2A-p14/ARF gene cluster, in the largest melanoma-neural system tumor (NST) syndrome family known to date by means of heterozygosity mapping based on microsatellite markers. Here, we used gene dose mapping with sequence-tagged site real-time PCR to locate the deletion end points, which were then ...
