DNA mismatch repair (MMR) genes have been described to participate in crossover events during meiotic recombination, which is, in turn, a key step of spermatogenesis. This evidence suggests that MMR family gene expression may be altered in infertile men with defective sperm production. In order to determine the expression profile of MMR genes in impaired(More)
Dermal neurofibromas (dNFs) are benign tumors of the peripheral nervous system typically associated with Neurofibromatosis type 1 (NF1) patients. Genes controlling the integrity of the DNA are likely to influence the number of neurofibromas developed because dNFs are caused by somatic mutational inactivation of the NF1 gene, frequently evidenced by loss of(More)
The study of somatic genetic alterations in tumors contributes to the understanding and management of cancer. Genetic alterations, such us copy number or copy neutral changes, generate allelic imbalances (AIs) that can be determined using polymorphic markers. Here we report the development of a simple set of calculations for analyzing microsatellite(More)
BACKGROUND About 5% of patients with neurofibromatosis type 1 (NF1) bear constitutional microdeletions that encompass NF1 (neurofibromin 1) and neighboring genes. These patients are characterized by the development of a high number of dermal neurofibromas (dNFs), mental retardation, and an increased risk of developing a malignant peripheral nerve sheath(More)
Malignant peripheral nerve sheath tumors (MPNSTs) are soft-tissue sarcomas that can arise either sporadically or in association with neurofibromatosis type 1 (NF1). These aggressive malignancies confer poor survival, with no effective therapy available. We present the generation and characterization of five distinct MPNST orthoxenograft models for(More)
