N-acetylglucosaminidase, myeloperoxidase and vascular endothelial growth factor serum levels in breast cancer patients

Inflammatory cells surround breast carcinomas and may act promoting tumor development or stimulating anti-tumor immunity. N-acetylglucosaminidase (NAG) has been employed to detect macrophage accumulation/activation. Myeloperoxidase (MPO) is considered a marker for neutrophils activity/accumulation. Vascular Endothelial Growth Factor (VEGF) is as strong pro-angiogenic cytokine. The aim of this study was to measure the systemic inflammatory response by measuring serum levels of NAG, MPO and VEGF in women diagnosed with breast cancer and associate this response to the peritumoral inflammatory infiltrate and to prognostic factors. Serum samples obtained from women with no evidence of disease (n = 31) and with breast cancer (n = 68) were analyzed for the activities of NAG, MPO and VEGF by enzymatic assay. Serum levels of NAG and VEGF were higher in healthy volunteers (P < 0.0001) and serum levels of MPO were higher in patients with breast cancer (P = 0.002). Serum levels of NAG were positively correlated to serum levels of MPO and VEGF (P < 0.0001 and P = 0.0012, respectively) and MPO and VEGF serum levels had also a positive correlation (P = 0.0018). The inflammatory infiltrate was not associated to serum levels of the inflammatory markers, and higher levels of MPO were associated to lymphovascular invasion negativity (P = 0.0175).

Proteínas ligantes do insulin-like growth factor (IGFBPs) e dominância folicular em vacas Bos taurus indicus puras e cruzadas

O objetivo deste estudo foi identificar um marcador bioquímico de folículos bovinos com diâmetro maior do que 10 mm, o qual poderia ser utilizado para identificar folículos dominantes nesta espécie. Líquido folicular era aspirado de folículos com diâmetros menores do que 5 mm, entre 5 e 10 mm e maiores do que 10 mm, provenientes de ovários de 37 fêmeas bovinas abatidas. Após aspiração, o líquido folicular (LF) era acondicionado em ependorfs etiquetados e congelados. Os padrões eletroforéticos em SDS-PAGE das proteínas do LF foram determinados e verificou-se que os folículos com diâmetro maior do que 10 mm apresentaram um polipeptídeo com PM entre 39 e 43 KDa identificado como a proteína ligante de IGF-3 (IGFBP-3), o qual não foi observado em folículos com diâmetro menor do que 5 mm e entre 5 e 10 mm. Este estudo sugere que este polipeptídeo possa ser utilizado como marcador bioquímico de folículos maiores do que 10 mm.

Expression and imprinting of insulin-like growth factor II (IGF2) and H19 genes in uterine leiomyomas

Genomic imprinting is defined as a gamete of origin-specific epigenetic modification of DNA leading to differential gene expression in the zygote. Several imprinted genes have been identified and some of them are associated with tumor development. We investigated the expression and the imprinting status of IGF2 and H19 genes in 47 uterine leiomyomas. Using allelic transcription assay, we detected the expression of the IGF2 gene in 10 of a total of 15 informative cases. No loss of imprinting, as determined by the finding of biallelic expression, was detected in any case. The expression of H19 gene was detected in 10 of 20 informative cases and the imprinting pattern was also maintained in all of them. Our data suggest that alterations in IGF2 and H19 genes expression by loss of imprinting do not occur in uterine leiomyomas. (C) 1999 Academic Press.
