BACKGROUND Bcl2 is an important prognostic parameter in human breast cancer. However, the evaluation of Bcl2 expression by immunohistochemistry is carried out using arbitrary scoring criteria. In the present study, we evaluated the clinical relevance of a novel, semiquantitative classification of the Bcl2 immunostaining based on both the distribution and the intensity of the staining reaction. ...

Bcl2 subfamily proteins, including Bcl2 and Bcl-X(L), inhibit apoptosis. As osteoblast apoptosis is in part responsible for osteoporosis in sex steroid deficiency, glucocorticoid excess, and aging, bone loss might be inhibited by the upregulation of Bcl2; however, the effects of Bcl2 overexpression on osteoblast differentiation and bone development and maintenance have not been fully investigat...

OBJECTIVE TRC105 is a chimeric immunoglobulin G1 monoclonal antibody that binds endoglin (CD105). This phase I open-label study evaluated the safety, pharmacokinetics and pharmacodynamics of TRC105 in patients with metastatic castration-resistant prostate cancer (mCRPC). PATIENTS AND METHODS Patients with mCRPC received escalating doses of i.v. TRC105 until unacceptable toxicity or disease pr...

The aim of this study was to determine the prognostic value of the angiogenesis rate in chronic periodontitis (CP). A total of 61 human gingival samples were taken from patients with CP (n = 40) obtained during open curettage with gingivectomy, healthy periodontia (n = 15), and reactive lymph nodes (n = 7). Quantitative immunocytochemistry studies of VEGF, CD31 (PECAM-1) and CD105 (endoglin) we...

OBJECTIVE Endothelial cells play a central pathogenetic role in ANCA-associated small-vessel vasculitis (AAV). Circulating endothelial cells (CECs), as a marker of endothelial damage, have been shown to be elevated in vasculitis. More recently, endothelial microparticles (EMPs) were found to be increased in active childhood vasculitis. The role of EMP in adult AAV and the relationship between E...

  Background and Objective: Approximately half of patients with diffuse large B-cell lymphoma are cured with current chemotherapy regimens. The purpose of this study was to evaluate Bax and Bcl2 expression and their relationship with the response to chemotherapy. Materials and Methods This study was a prospective analysis on 44 patients with diffuse large B-cell lymphoma. Their specimens we...

In this paper, utilization of clustering algorithms for data fusion in decision level is proposed. The results of automatic isolated word recognition, which are derived from speech spectrograph and Linear Predictive Coding (LPC) analysis, are combined with each other by using fuzzy clustering algorithms, especially fuzzy k-means and fuzzy vector quantization. Experimental results show that the ...

INTRODUCTION Although the human umbilical cord (UC) has been previously considered a medical waste, its use as a main source of fetal stem cells for regenerative medicine applications has increased over the past few years. The aim of the study was to assess the impact of the maternal age on the expression of mesenchymal stem cells (MSC) markers CD105 and CD29 in the different areas of human UC....

High-level BCL2 expression is seen in most patients with chronic lymphocytic leukemia (CLL) in the absence of BCL2 chromosomal translocation. A single nucleotide polymorphism (SNP; -938C>A) within an inhibitory region of the BCL2 promoter has been reported to regulate BCL2 protein expression and to be associated with adverse prognostic features in CLL. We screened 276 patients with CLL for this...

Microtubule inhibitor-induced Bcl2 phosphorylation is detrimental to its antiapoptotic function. Phosphorylation of Bcl2 predominantly occurs on two serine residues (70 and 87) in cells arrested at G2-M phase by microtubule disarraying agents. Phospho Bcl2 can associate with a cis-trans peptidyl prolyl isomerase, Pin1. Pin1 and its homologues are known to target the proline residue carboxyl ter...
