In this study by IHC, with this MAb, we found a positive reaction in 47.5% of breast tumor samples, showing a different pattern of expression among malignant, benign and normal samples; nevertheless; no statistically significant difference in percentage of expression was found. In cancer samples, we did not find any significant difference among different stages. Our results are in agreement with Madjd et al since they found that Ley/b is expressed in 44% of breast cancer samples, employing SC101 MAb although this MAb reacts with both Lewis y and Lewis b [1]. On the other hand, as it was not
surprising, MUC1 was detected in all samples employing many anti-MUC1 antibodies (16); {Selleck Anti-infection Compound Library|Selleck Antiinfection Compound Library|Selleck Anti-infection Compound Library|Selleck Antiinfection Compound Library|Selleckchem Anti-infection Compound Library|Selleckchem Antiinfection Compound Library|Selleckchem Anti-infection Compound Library|Selleckchem Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|Anti-infection Compound Library|Antiinfection Compound Library|buy Anti-infection Compound Library|Anti-infection Compound Library ic50|Anti-infection Compound Library price|Anti-infection Compound Library cost|Anti-infection Compound Library solubility dmso|Anti-infection Compound Library purchase|Anti-infection Compound Library manufacturer|Anti-infection Compound Library research buy|Anti-infection Compound Library order|Anti-infection Compound Library mouse|Anti-infection Compound Library chemical structure|Anti-infection Compound Library mw|Anti-infection Compound Library molecular weight|Anti-infection Compound Library datasheet|Anti-infection Compound Library supplier|Anti-infection Compound Library in vitro|Anti-infection Compound Library cell line|Anti-infection Compound Library concentration|Anti-infection Compound Library nmr|Anti-infection Compound Library in vivo|Anti-infection Compound Library clinical trial|Anti-infection Compound Library cell assay|Anti-infection Compound Library screening|Anti-infection Compound Library high throughput|buy Antiinfection Compound Library|Antiinfection Compound Library ic50|Antiinfection Compound Library price|Antiinfection Compound Library cost|Antiinfection Compound Library solubility dmso|Antiinfection Compound Library purchase|Antiinfection Compound Library manufacturer|Antiinfection Compound Library research buy|Antiinfection Compound Library order|Antiinfection Compound Library chemical structure|Antiinfection Compound Library datasheet|Antiinfection Compound Library supplier|Antiinfection Compound Library in vitro|Antiinfection Compound Library cell line|Antiinfection Compound Library concentration|Antiinfection Compound Library clinical trial|Antiinfection Compound Library cell assay|Antiinfection Compound Library screening|Antiinfection Compound Library high throughput|Anti-infection Compound high throughput screening| in consequence, correlation analysis was not necessary. Klinger et al confirmed that the majority of cancer cells derived from epithelial tissue express Lewis y type difucosylated oligosaccharides on their plasma membranes; they have also found that ABL 364 MAb against this carbohydrate which is present
in erbB receptor side chains are capable of inhibiting erbB receptor mediated signaling [36]. Other authors found a novel function for soluble Ley/H as an endothelial-selective and NVP-BSK805 research buy cytokine inducible as well as a potent angiogenic mediator in both in vitro and in vivo bioassays [37]. Cancer antigens expressed at the cell surface are generally glycolipids or glycoproteins [12, 38] which may express in their molecules blood group related Lewis antigens [2]. The non appropriate biosynthesis or processing of carbohydrate
structures may contribute to the disordered behaviour of tumor cells [39]. Lewis y carbohydrate may participate in natural humoral immune response; antibodies are ideally suited for TCL eradicating pathogens from bloodstream and early tissue invasion. With regard to cancer cells, passively administered and vaccine induced antibodies have accomplished this concept, limiting tumor cells and systemic or intraperitoneal micrometastases in a variety of preclinical models [12]. Many protocols developing anti-Lewis y vaccines have been performed [12, 40, 41]. In this report, we found that Lewis y/IgM/CIC Vorinostat price levels correlated with Lewis y/IgG/CIC levels and MUC1/CIC (IgG and IgM) levels and also that Lewis y/IgG/CIC levels correlated with MUC1/IgG/CIC levels. These correlations may be related with the fact that MUC1 may be a carrier of Lewis y epitope. Von Mensdörff-Pouilly et al [42] found that naturally occurring MUC1 antibodies seem to check disease spread in breast cancer patients, possibly by destroying blood-borne isolated disseminated tumor cells (micrometastases) which eventually could lead to metastatic disease and death. Silk et al found significantly higher anti-MUC1 IgG levels in abnormal versus normal colorectal location [43].
