skin cancer is one of the most important type of cancers in the world. in this way, molecular investigation in order to detect some novel mechanisms and polymorphisms involved in cancer development can be impressive and vital. in this way, the aim of this study was the histopathological investigation of skin cancer and its relationship with polymorphism of cdkn2a gene. this case-control study w...
OBJECTIVE In the present study, we aimed to validate the type 2 diabetes susceptibility alleles identified in six recent genome-wide association studies in the HHEX/KIF11/IDE (rs1111875), CDKN2A/B (rs10811661), and IGF2BP2 (rs4402960) loci, as well as the intergenic rs9300039 variant. Furthermore, we aimed to characterize quantitative metabolic risk phenotypes of the four variants. RESEARCH D...
BACKGROUND The human 9p21.3 chromosome locus has been shown to be an independent risk factor for atherosclerosis in multiple large-scale genome-wide association studies, but the underlying mechanism remains unknown. We set out to investigate the potential role of the 9p21.3 locus neighboring genes, including Mtap, the 2 isoforms of Cdkn2a, p16Ink4a and p19Arf, and Cdkn2b, in atherosclerosis usi...
BACKGROUND CDKN2A and CDK4 are high risk susceptibility genes for cutaneous malignant melanoma. Melanoma families with CDKN2A germline mutations have been extensively characterised, whereas CDK4 families are rare and lack a systematic investigation of their phenotype. METHODS All known families with CDK4 germline mutations (n=17) were recruited for the study by contacting the authors of publi...
PURPOSE The aim of the current study was to examine the prognostic relevance of the CDKN2A tumor suppressor pathway in gastrointestinal stromal tumors (GIST). EXPERIMENTAL DESIGN We determined the mRNA expression of p1(INK4A), p14(ARF), CDK4, RB1, MDM2, TP53, and E2F1 by quantitative reverse transcription-PCR in 38 cases of GISTs and correlated the findings with clinicopathologic factors, inc...
Major risk factors for melanoma include many nevi, especially dysplastic nevi, fair pigmentation, freckling, poor tanning ability, and germ line mutations in the CDKN2A, CDK4, or MC1R genes. We evaluated the relationship between MC1R and melanoma risk in CDKN2A melanoma-prone families with extensive clinical and epidemiologic data. We studied 395 subjects from 16 American CDKN2A families. Major...
Salivary gland tumours are rare tumours characterized by histopathologic complexity and a wide variety of morphologic features. Studies on genetic changes in different histological subtypes of salivary gland tumours are important to better understand molecular pathogenetic mechanisms and to identify diagnostic and prognostic markers. Data are even more scanty dealing with unusual subtypes of th...
Medullary thyroid carcinoma (MTC), a neuroendocrine tumor originating from thyroid parafollicular cells, has been demonstrated to be associated with mutations in RET, HRAS, KRAS and NRAS. However, the role of other genes involved in the oncogenesis of neural crest tumors remains to be fully investigated in MTC. The current study aimed to investigate the presence of somatic mutations in BRAF, CD...
BACKGROUND Lifetime melanoma risk of mutation carriers from families with a germline mutation in the CDKN2A gene is estimated to be 67%. The necessity to include family members in a melanoma surveillance program is widely endorsed, but there is no consensus on which family members should be invited. METHODS In a retrospective follow-up study, we investigated the yield of surveillance of first...
