The chemokine receptor CCR5 is encoded by the CMKBR5 gene located on the p21.3 region of human chromosome 3, and constitutes the major co-receptor for the macrophage-tropic strains of HIV-1. A mutant allele of the CCR5 gene, Delta ccr5 , was shown to provide to homozygotes with a strong resistance against infection by HIV. The frequency of the Delta ccr5(More)
Only a few cases with breast cancer and neurofibromatosis type 1 (NF1) have been reported in the literature. Here, we present a family with a history of neurofibromatosis and breast cancer. No hereditary NF1 mutation was observed in this case. Loss of heterozygosity (LOH) analyses of the breast tumor revealed LOH in the NF1 region. In this family, the(More)
Pluripotent stem cells (PSCs) have the capacity to differentiate into any cell type of the body. Therefore, induced pluripotent stem cells (iPSCs) are seen as a promising solution for patient-specific cell therapies. However, the safety is major issue for in vitro methods that are used in induction of pluripotency and also in differentiation of PSCs toward(More)
Li-Fraumeni syndrome is an autosomal dominant disorder that is characterized by various types of cancer in childhood and adult cases. Although hereditary TP53 mutation is very rare in different human cancers, it has been frequently reported in Li-Fraumeni syndrome. On the other hand, hereditary mutations of TP57KIP2, P15INK4B, and P16INK4A, which affect the(More)
In this study, MLPA assay was performed for detection of large rearrangements of BRCA1 and BRCA2 genes in 16 familial, 29 early onset, 3 male breast cancer, and 2 bilateral breast/ovarian cancer high risk Turkish index cases. MLPA assay for all exons of both genes and for 1100delC variant of CHEK2 gene were performed. Analyses, revealed no large genomic(More)
The occurrence of acute transformation during the treatment of chronic myeloid leukemia (CML) is still a poorly understood mechanism. In this disease p53, p16INK4A, p15INK4B, p57KIP2 mutations and p15INK4B/p16INK4A homo/hemizygous deletions were analyzed in the initial diagnosis phase and during the treatment phase of twelve CML cases, in order to establish(More)
Scrotal cancer is the first described occupational cancer. The frequency of occupation-related scrotal cancer is very rare because of better hygiene and protective clothing. Human papilloma viruses (oncogenic types 16 and 18) were reported as the causative agents in the pathogenesis of scrotal cancers. E5, E6, and E7 proteins, expressed by human papilloma(More)
Distribution and prevalence of germline mutations in BRCA1 and BRCA2 differ among different populations. For the Turkish population, several studies have addressed high-risk breast cancer and ovarian cancer (BC-OC) patients. In most studies, both genes were analyzed in part, and a quite heterogeneous mutation spectrum was observed. For high-risk Turkish(More)
Multiple myeloma (MM) is a malignancy arising from mature plasma cells in the bone marrow and usually presents with bone destruction, hypercalcemia, anemia, renal damage, and increased susceptibility to infection. The etiology of MM is unknown, with no established lifestyle, occupational, or environmental risk factors. Because MM is an uncommon disease,(More)
