The involvement of HER2 and p53 status in the regulation of telomerase in irradiated breast cancer cells
(2009)
Cancer cell characteristics may play a pivotal role in the response to therapy by activating or deactivating different molecular pathways. In the present study, we investigated the implication of breast cancer cell features, ...
Association of interleukin-1A, interleukin-1B and interleukin-1 receptor antagonist gene polymorphisms with multiple myeloma
(2007)
Interleukin-1 (IL-1) is a cytokine involved in the maturation and proliferation of B cells and plays a significant role in the development of lytic bone lesions, a major clinical feature of multiple myeloma (MM) patients. ...
Clinical, immunophenotypic, and molecular profiling of trisomy 12 in chronic lymphocytic leukemia and comparison with other karyotypic subgroups defined by cytogenetic analysis
(2006)
In a cohort of 130 unselected chronic lymphocytic leukemia (CLL) patients, 73 cases had normal karyotypes, 57 cases had abnormal karyotypes, and 22/57 cases carried more than one abnormality. Trisomy 12 (+ 12) was the most ...
Report of novel chromosomal abnormalities in a series of 130 chronic lymphocytic leukemia patients studied by classic cytogenetic analysis
(2006)
One-hundred-and-thirty typical, unselected CLL cases were studied by conventional cytogenetic analysis. Seventy-three patients (56.2%) had normal karyotype ('normal sub-group'), while 57/130 patients (43.8%) had abnormal ...
Report of two novel chromosomal translocations in chronic lymphocytic leukemia
(2005)
Two novel chromosomal translocations were identified in 2 patients with chronic lymphocytic leukemia (CLL). Case 1: 60 year-old male, stage Rai 0/Binet A, with mutated immunoglobulin heavy (IgH) and lambda (Iglambda) light ...
Association of repeat polymorphisms in the estrogen receptors alpha, beta (ESR1, ESR2) and androgen receptor (AR) genes with the occurrence of breast cancer
(2008)
Genetic variation in genes involved in estrogen biosynthesis, metabolism and signal transduction have been suggested to play a role in breast cancer. To determine the possible contribution of genetic variation in the ESR1 ...
Correlation of promoter hypermethylation in hTERT, DAPK and MGMT genes with cervical oncogenesis progression
(2009)
DNA hypermethylation occurs during the multi-step process of cervical carcinogenesis. We investigated whether the methylation status in the promoter region of a potential oncogene, the human telomerase reverse transcriptase ...
Epigenetic regulation of hTERT promoter in hepatocellular carcinomas
(2009)
Although hepatocellular carcinoma (HCC) is the fifth most common cancer worldwide, the molecular pathogenesis of the disease has not been elucidated. Several studies have shown that telomerase activity and hTERT expression ...
