Overexpression of HER-2\neu receptor protein in Urinary Bladder Carcinoma, An Immunohistochemical Study.
...Show More Authors

Background: Bladder carcinoma is one of the most common cancer worldwide, it accounts for 6.5% of all cancers, with highest incidence in industrialized countries .It represents the fourth most common cancer in men and the eighth in women. Bladder carcinoma depends in its pathogenesis on a combination of genetic and environmental factors, these factors produce phenotypic changes that allow normal transitional cells to become cancerous and finally acquire the “malignant phenotype".  Many attempts had been tried to explore the role of some genetic abnormalities encountered in bladder carcinoma. It has indicated that many genetic abnormalities may underline the pathogenesis of cancer evolution of urinary bladder like VEGF , P53, Bcl2 and RB, but nowadays a scientific efforts have raised the possible role of Her-2/neu in bladder carcinoma, and the rate of its overexpression in bladder carcinoma is ranging from 2% - 74%. 
Objective: To estimate immunohistochemical expression of HER-2\neu receptor protein in Urinary Bladder Carcinoma in relation to other parameters; sex grade, pattern of tumor and stage of tumor .
Methods: The present work is performed in the Department of Pathology and Forensic medicine, College of Medicine, Kufa University. Formalin fixed, Paraffin-embedded blocks from 60 (43 males and 17 females) patients with urinary bladder carcinoma were included in this study. A group of 12 patients with chronic cystitis were included as a control group. Avidin-Biotin Complex method was employed for immunohistochemical detection of HER-2\neu.
Results: HER-2\neu overexpression was positive in 41.6% of urinary bladder carcinoma, while there was no expression in benign bladder tissue (P<0.05). HER-2\neu immunohistochemical staining was positively correlated with, grade and stage of urinary bladder carcinoma (P<0.05).
Conclusion: These findings support the role of HER-2\neu in the carcinogenesis of urinary bladder carcinoma regarding behavior, and aggressiveness, and thus HER-2\neu could be considered as a poor prognostic parameter in urinary bladder carcinoma.

Cell Surface Expression of 70 KDa Heat Shock Proteins and P21 in Normal Oral Mucosa, Oral Epithelial Dysplasia and Squamous Cell Carcinoma (An Immunohistochemical Study)
...Show More Authors

Background: Oral SCC is a complex malignancy where environmental factors, viral infections and genetic alterations most likely interact, and thus give rise to the malignant condition. The HSP70 play a direct role in apoptosis inhibition by aligning the improved integrity of a cell’s proteins with the improved chances of that particular cell’s survival.P21 gene produces p21 protein which is a potent cyclin-dependent kinase inhibitor that plays a significant role in carcinogenesis. The aims of the study were to evaluate and compare the immun-histochemical expression of the HSP70 and cell cycle protein p21in NOM, OED, and OSCC. Correlate both marker expressions with each other. Materials and methods: Forty six formalin-fixed, par

Immunohistochemical Assessment of SOX2 Expression in Iraqi Patients with Gastric Carcinoma (GC)
...Show More Authors

Objective: To evaluate whether the SOX2 protein could be used as a predictor in patients with GC and to assessment the correlation between the IHC expression of the SOX2 protein and the various clinic pathological Parameters as age, sex, histopathological subtypes, grade and stage of the tumor by immune-histochemical Technique. This is a retrospective study conducted on 60 randomly selected patients (30) normal versus (30) GC, at the pathology department of the Gastroenterology and Hepatology Teaching Hospital & some private hospitals. It were collected and diagnosed during the period between from 2014 to 2018. From each block were stained with H&E and IHC stained for SOX2.

Validity of serum Toll-like receptor-2 (TLR-2) in women with breast tumor
...Show More Authors

Background: Toll-like receptor -2 (TLR-2)play important roles in tumor biology; by activation and promotion of tumor cell proliferation, resistance to apoptosis andalso, enhancement of tumor cell invasion and metastasis by regulating metalloproteinase and integrin’s.As toll-like receptors are widely expressed on tumor cells and participatein the initiation and progression of cancer, they may thus serve an important target and have an effective perspective on breast cancer treatment.
Objectives:The aims of the present study was to determine the levels of TLR-2 in the sera of healthy people and patients with benign and malignant breast tumors and also to investigate the validity of using TLR-2 as specific diagnostic markers of breast

Chromogenic in Situ Hybridization Technique versus Immunohistochemistry in Assessment of HER2/neu Status in 448 Iraqi Patients with Invasive Breast Carcinoma
...Show More Authors

BACKGROUND: The rapidly growing knowledge regarding factors controlling tumour growth, with the new modalities of therapy acting on the biological activity of the tumours draw the attention of most cancer researches nowadays and represent a major focus for clinical oncology practice. For the detection of HER2/neu protein overexpression and gene amplification, immunohistochemistry (IHC) and in-situ hybridisation (ISH) is the recommended techniques, respectively, with high concordance between the two techniques. The current United Kingdom recommendations for HER2/neu testing are either for a two-tier system using IHC with reflex ISH testing in equivocal positive cases, or a one-tier ISH strategy. AIM: To compare the results of HER2/neu gene s
