BACKGROUND Carrying the cyclin-dependent kinase inhibitor 2A (CDKN2A) germline mutations is associated with a high risk for melanoma. Penetrance of CDKN2A mutations is modified by pigmentation characteristics, nevus phenotypes, and some variants of the melanocortin-1 receptor gene (MC1R), which is known to have a role in the pigmentation process. However, investigation of the associations of bo...

ZBP-89 (Zfp148, ZNF148) is a Kruppel-type zinc-finger family transcription factor that binds to GC-rich DNA elements. Earlier studies in cell lines demonstrated that ZBP-89 cooperates with Wnt β-catenin signaling by inducing β-catenin gene expression. Since β-catenin levels are normally highest at the crypt base, we examined whether ZBP-89 is required for stem cell maintenance. Lineage-tracing ...

Germline mutations of CDKN2A at 9p21 have been shown to predispose to disease in melanoma pedigrees worldwide. However, there remains a significant proportion of melanoma pedigrees with evidence of linkage to 9p21 in which mutations in CDKN2A have not been detected. Investigation of other potential tumour suppressor genes at 9p21 and the promotor of CDKN2A has been unable to explain genetic pre...

OBJECTIVE Common genetic variants in a 58-kb region of chromosome 9p21, near the CDKN2A/CDKN2B tumor suppressor locus, are strongly associated with coronary artery disease. However, the underlying mechanism of action remains unknown. METHODS AND RESULTS We previously reported a congenic mouse model harboring an atherosclerosis susceptibility locus and the region of homology with the human 9p2...

BACKGROUND While qualitative analysis of methylation has been reviewed, the quantitative analysis of methylation has rarely been studied. We evaluated the methylation status of CDKN2A, RARβ, and RASSF1A promoter regions in non-small cell lung carcinomas (NSCLCs) by using pyrosequencing. Then, we evaluated the association between methylation at the promoter regions of these tumor suppressor gene...

Previous studies have reported that inhibitor of DNA binding 1 (ID1) exerts an oncogenic role in a number of tumors. In the present study, the role of ID1 in the growth, invasion and migration of salivary adenoid cystic carcinoma (SACC) cells was investigated. ID1 expression in clinical SACC samples was compared with that in normal salivary tissues using immunohistochemical staining, and the co...

BACKGROUND AND OBJECTIVES Disruption of either the p14ARF- mdm2- p53 or p16INK4A- Rb1 pathways produces a breakdown of regulatory mechanisms and creates a gateway for tumorigenesis. Since the incidence and clinical implications of abnormalities of TP53, CDKN2A (encoding for p16 and p14) and MDM2 genes (chromosome 12) in multiple myeloma (MM) is not clear, we investigated allelic loss at the for...

BACKGROUND The ability to identify individuals at increased risk of cancer is of immediate clinical relevance. Germline mutations in the CDKN2A locus, encoding the key tumor suppressor proteins p16/INK4A and p14/ARF, are frequently present in kindreds with hereditary cutaneous melanoma but have seldom been reported in families with genetic susceptibility to head and neck squamous cell carcinoma...

BACKGROUND Genome-wide association studies for coronary artery disease/myocardial infarction revealed a 58 kb risk locus on 9p21.3. Refined genetic analyses revealed unique haplotype blocks conferring susceptibility to atherosclerosis per se versus risk for acute complications in the presence of underlying coronary artery disease. The cell proliferation inhibitor locus, CDKN2A, maps just upstre...
