BACKGROUND c-KIT expression has been related to bone metastasis in human prostate cancer, but whether c-KIT expression can be similarly classified in canine prostatic tissue is unknown. This study assessed c-KIT and Ki67 expression in canine prostate cancer (PC). c-KIT gene and protein expression and Ki67 expression were evaluated in forty-four canine prostatic tissues by immunohistochemistry, ...

Minichromosome maintenance (MCM) proteins are essential components for DNA replication, and also prognostic markers for various human tumors. MCM-positive but Ki67-negative cells (e.g. primary oocytes) are thought to be licensed non-proliferating populations, and are significantly correlated with the clinicopathological profiles of some human tumors. In the present study, we evaluated the expre...

Introduction Several studies indicate that ;50% of patients with positive biopsies for DCIS of the breast may develop invasive breast cancer within 1–24 years of diagnosis (1). The biological mechanisms involved in the progression of DCIS to invasive cancer are not fully understood. Although Ki67 labeling indices increased in invasive breast cancer (2, 3), there are limited data on this marker ...

Biological diversity of breast cancer presents challenges for personalized therapy and necessitates multiparametric approaches to understand and manage the disease. Multiple protein biomarkers tested by immunohistochemistry (IHC), followed by digital image analysis and multivariate statistics of the data, have been shown to be effective in exploring latent profiles of tumor tissue immunophenoty...

AIMS (a) To assess the expression patterns of HER2/neu, steroid receptors (ER and PR), Ki67 and p53 in invasive ductal cancer (IDC) and IDC associated with carcinoma in situ (IDC/DCIS) and (b) to determine if there is a differential expression of these molecular markers between IDC and IDC/DCIS. MATERIALS AND METHODS Paraffin-fixed breast cancer samples, diagnosed with only one histological i...

Background: Breast carcinoma (BC) is the most commonly occurring cancer. Nearly 15–20% of breast carcinomas are HER2 overexpressing subtype. Patients with this subtype have a poor prognosis fewer therapeutic options. Increased glucose transporters expression crucial for enhancing uptake observed in several tumors. Overexpression IL-8 has been found neoplastic epithelial cells various malignanci...

Background: The mutation of von Hippel-Lindau (VHL) tumor suppressor gene is closely related with tumorigenesis of renal clear cell carcinoma (RCCC). Ki67 is a specific cell nuclear antigen closely related with the cell cycle, generally appearing in the stages S, G2 and M of the cell amplification process, and it can emphasize the specific state of cell amplification very accurately. This study...

Objective(s): Epidemiological and biochemical studies conducted over the past two decades have established a strong link between type 2 diabetes mellitus (T2DM) and Alzheimer’s disease (AD). However, the exact mechanisms through which aberrations in insulin signaling associated with T2DM contribute to cognitive decline are not yet known. Materials and Methods: In an effort to explore possible m...

The aim of the present study was to investigate the functions of RACK1 and its involvement in mechanisms of prostate cancer (PC) cell proliferation, invasion and metastasis. The proliferation, invasion and metastasis of stably transfected DU145 cells with RACK1 was evaluated in vitro as well as in vivo following the establishment of nude mouse models. The expression of Ki67, RACK1, PTEN and and...

Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous group of lymphoid malignancies, which counts for more than a third of non-Hodgkin's lymphoma cases. The aim of the current study is to evaluate the prognostic role of several immunohistochemical (IHC) markers involved in the pathological process of DLBCL. This is a retrospective analysis of the 97 de novo DLBCL patients admitted between J...
