Telomeric dysfunction has been proposed as an emerging prognostic factor in chronic lymphocytic leukemia (CLL). We have explored the relationship between telomere length (TL) and chromosome alterations studied by fluorescence in situ hybridization (FISH) and conventional cytogenetics in 107 newly diagnosed CLL patients; 61 normal controls were also(More)
In this study, we explored changes in the expression of the telomere maintenance genes, TRF1, TRF2 and TANK1 in patients with monoclonal gammopathy of undetermined significance (MGUS) and multiple myeloma (MM). Results were correlated with human telomerase reverse transcriptase (hTERT ) expression, telomere length (TL) and clinicopathological(More)
Mantle cell lymphoma (MCL) is an aggressive lymphoid neoplasm with poor prognosis. Acquired telomerase reverse transcriptase gene promoter (TERTp) mutations are among the most frequent somatic non-coding mutations in cancers. In this study, the prevalence of TERTp mutations in 24 MCL and 21 other lymphoid neoplasias (oLN) was investigated. Eight MCL samples(More)
Mantle cell lymphoma (MCL) is a well defined lymphoid neoplasm genetically characterized by the t(11;14)(q13;q32). Telomeres play an essential role in preserving chromosomal integrity and genomic stability; their shortening can lead to telomere dysfunction and chromosomal instability, a critical factor in cancer development. In this study, telomere length(More)
Enzymatic hydrolysis of acetylated nucleosides using microbial whole cells has been carried out for the first time. Unlike Candida antarctica B lipase-catalysed alcoholysis, none of the tested microorganisms displayed a common deacetylation profile. Depending on the substrate and the biocatalyst used, 5′-selective deprotection or mixtures of mono(More)
The core complex of telomere-associated proteins, named the shelterin complex, plays a critical role in telomere protection and telomere length (TL) homeostasis. In this study, we have explored changes in the expression of telomere-associated genes POT1, TIN2, RAP1 and TPP1, in patients with monoclonal gammopathy of undetermined significance (MGUS) and(More)
Telomere length (TL) is currently used as an emerging biomarker in understanding the development/progression of hematological malignancies. The absolute quantitative PCR (qPCR) methodology has allowed the study of TL from a variety of mammalian tissues, but it has not been tested for bone marrow (BM) samples. In this study, we have examined the relationship(More)
BACKGROUND Glutathione S-transferase P1 (GSTP1) is an important phase II enzyme involved in detoxification of carcinogens. GSTP1 gene overexpression has been observed in a variety of human cancers but there are no studies in plasma cell disorders. The aim of this study was to examine GSTP1 mRNA expression level in multiple myeloma (MM) and monoclonal(More)
Telomerase, shelterin proteins and various interacting factors, named non-shelterin proteins, are involved in the regulation of telomere length (TL). Altered expression of any of these telomere-associated genes can lead to telomere dysfunction, causing genomic instability and disease development. In this study, we investigated the expression profile of a(More)
