Cox regression analyses revealed associations of ER/PR status and uPA system users with regard to clinical outcomes of breast cancer. Conclusions expression was increased in either ER? or PR? cancers similar to that of protein content in ER?/PR? carcinomas, suggesting sex hormones regulate the uPA system in breast cancer. Results revealed protein content of uPA system users was related to ER/PR status of main lesions. Use of LCM\procured carcinoma cells uncovered associations between expression of known malignancy?associated genes and protein content of uPA system members. Collectively, results indicate evaluation of ER and PR protein of main breast cancers combined with analyses of uPA, uPAR, and PAI\1 protein content improves assessment of clinical outcomes. valuevalue below 0.3.

Interrelationships of biomarker protein status of the primary breast carcinoma as a function of individual age Scatter plots were constructed in order to ascertain the relationship between individual age and quantified biomarker protein in the primary breast cancer (Physique ?(Figure1).1). Linear regression analyses were performed, and a genes was examined through construction of violin plots GSK256066 according to ER+ or ER? status of the primary lesion (Physique ?(Figure4).4). An adjusted gene was significantly elevated in ER? cells compared to ER+ cells (Physique ?(Figure4A).4A). Analyses also indicated that expression of either or genes was significantly elevated in ER? breast cancer cells compared to ER+ cells at an adjusted gene was not significantly expressed in regard to ER status of the primary lesion. Open in a separate window Physique 4 Violin plots utilizing relative expression of genes of the uPA system estimated by microarray compared to either ER or PR status of the breast main lesion for 247 patients. Breast carcinomas were classified as either ER+ or ER? and either PR+ or PR? utilizing measurements obtained by either EIA or radio\ligand binding In addition, PR status of the primary lesion was evaluated in relation to expression of each candidate gene in LCM\procured cells. Therefore, violin plots of PR+ and PR? lesions were constructed in relation to relative gene expression of each gene of interest (Physique ?(Figure4).4). Analyses indicated that expression of and its respective receptor, and genes was detected in PR? breast malignancy cells (Physique ?(Physique44G,H). To determine whether there is a relationship between either ER or PR protein levels in a main lesion GSK256066 and relative expression of each gene of interest, scatter plots were constructed. Total ER or PR protein content (fmol/mg P) of each main breast carcinoma was plotted as a function of relative expression for each gene of interest (Physique ?(Physique5).5). Note that since microarray analyses also provided results of gene expression in LCM\procured cells, determination of these associations was possible with each of the four users of the plasminogen activator system.
