Immunohistochemical demonstration of tumor-associated markers may be valuable as an adjunct to conventional histology for determination of malignancy development in oral mucosal diseases. Accordingly, the present study determined the distribution of some important tumor markers such as heat shock proteins (HSP), fibroblast growth factors (FGF) and transferrin receptors (TF-R) in 22 samples ...
background: materials and methods: this was a cross-sectional study carried out among 70 samples, including 10 samples from normal healthy mucosa categorized into group 1, group 2 (30 olp), and group 3 (30 oed) samples. five sections (4 μm thick) were obtained and stained with monoclonal antibodies such as ki-67, p53, bcl-2, and bax and analyzed for number of positive cells and also for inten...
Introduction: Survivin is a new member of the Inhibitor Apotosis Protein family (IAP) which plays an important role in the regulation of both cell cycle and apoptosis. Its distinct expression in tumor cells as compared to normal adult cells introduces Survivin as the fourth transcriptom demonstrated in tumors. Breast cancer is the most common malignancy among women and scientist`s efforts to cl...
Abstract Background and Objective: Identification of malignant cells and the type of malignancy in Effusionsis very important. The main aim of this study was to differentiate between reactive mesothelial cells and malignant cells and to determine the type of the tumor cells in effusions with the aid of tumor markers Creatine Kinase (CK), EMA and CEA. Material and Methods: Forty serous flui...
Hepatocellular carcinoma (HCC) is the 5th commonest malignancy worldwide and is the third most common cause of cancer-related death. The prevalence is different in the world. The ability to predict patients at higher risk of recurrence and with a poor prognosis would help to guide surgical and chemotherapeutic treatment according to individual risk. As understanding of hepatocarcinogenesi...
Testicular schwannoma is a very rare benign scrotal tumor. It is a painless mass, but sometimes referred because of pain or sensory losses. Tumor markers are normal and radical orchidectomy is its best treatment. Here we present an unusual case of intrascrotal schwannoma in a 57 year old man, with a review of the literature.
Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...
cancer stem cells (csc) are the tumor-associated cells existed within tumors or hematological cancers which share characteristics similar to normal stem cells. the common characteristics of a normal stem cell and a csc are their differentiation capacity and self-renewal in tumors. the expression pattern of csc markers differs depending on the type and location of cancers. cd molecules are proba...
