In DCIS-IDC, GnT-III expression was associated with high nuclear grade tumors (p = 0.039) while the presence of PHA-L and WGA were inversely related to HER-2 expression (p = 0.001; p = 0.036, respectively).
The diagnostic models were constructed based on 9 candidate lectins (e.g., PHA-E+L, BS-I, and NPA) that exhibited significant alterations of salivary glycopatterns, which achieved better diagnostic powers with an AUC value >0.750 (p<0.001) for the diagnosis of BB (AUC: 0.752, sensitivity: 0.600, and specificity: 0.835) and I stage breast cancer (AUC: 0.755, sensitivity: 0.733, and specificity: 0.742) in the validation cohort.
LBR mRNA expression was directly associated with tumor grade (grade 1 vs. grade 3 - 0.00 vs. 0.00; p = 0.0479) and Nottingham Prognostic Index (NPI1 vs. NPI3 - 0.00 vs. 0.00; p = 0.0551).
A transcriptional signature of the pan-cyclin-dependent kinase (Cdk) inhibitor PHA-793887 was evaluated as a potential pharmacodynamic and/or response biomarker in tumor and skin biopsies from patients treated in a phase I clinical study.
In this study, we have generated L(4)-PHA-displaying BNCs (PHA-BNCs) and examined whether L(4)-PHA could retarget the BNCs to malignant tumors as a "biosensor" distinguishing tumor metastaticity.
Treatment of tumor-derived T lymphocytes with the selective Met inhibitor PHA-665752 at nanomolar concentrations abolished phosphorylation of Met and downstream effectors and led to caspase-mediated apoptosis.I.v. administration of PHA-665752 to transgenic mice bearing lymphomas in exponential growth phase led to a significant decrease in tumor growth and, in some cases, to tumor regression.
One hundred thirty-two metaphases were obtained on PHA-stimulated peripheral blood; 123 of them presented an extra chromosome Y. Fluorescence in situ hybridization using a Y satellite III probe showed the presence of a sole copy of chromosome Y in the tumor cells precluding a direct relationship between the extra chromosome Y and the initiation of the tumor.
The cytological behavior of the spindle apparatus was studied in cells prone to nondisjunction (ND), i.e., PHA-stimulated lymphocytes derived from children suffering from different types of neoplasia.
