Immunohistochemical Targeting of p110β Isoform of phosphatidylinositol 3-kinase co-associated with Cyclin-Dependent Kinase 1 in a Group of Tissues from Iraqi Patients with Breast Cancer
...Show More Authors

Background: While two-thirds of breast cancers express hormone receptors for either estrogen (ER) and/or progesterone (PR) , genetically altered PI3K pathway was found in more than 70% of ER-positive breast cancers.An aberrant activity of cyclin-dependent kinase 1 (CDK1) in a wide variety of human cancers has selectively constituted an attractive pharmacological targets in MYC-dependent human breast cancer cells.

Aim of the study:  Role of p110-beta as well as and CDK 1  in the pathogenesis of subset of breast cancers and contribution in their carcinogenesis.

Type of the study: is a retrospective study

Methods: This retrospective research enrolled 70 paraffin embedded breast tissue blocks which were retrieved from archives of the period 2011 till 2017 at major hospitals and private histopathological laboratories as well as Forensic Medicine Institute in Baghdad. They comprised 30 breast cancers, 25 benign breast tumors and 15 apparently normal breast autopsies. Two 4 mm - thick sections were specified on positively charged slides for monoclonal primary p110 as well as and CDK 2 antibodies using immune-enzymatic antigen detection system for immunohistochemistry (IHC) techniques.

Results: Seventeen out of 30 (56.7%) of the total breast cancer cases in this study showed positive immunohistochemistry reaction(IHC) for detection of P110- beta gene expression in these tissues.  In the benign group, 6 out of 25 cases (24%) revealed positive IHC signals. None of control group presented positive signals. The differences begroup tween the percentages of P110-beta in breast cancers and each of control group and benign breast tumors group are statistically very highly significant (P value = < 0.0001). The expression of CDK1 was detected in 53.3% (16 out of 30) of breast cancers tissues and in 44% (11 out of 25) benign breast tumors, whereas none of control group of tissues showed CDK1- expression.

Conclusions: The present data indicate that p110-beta as well as and CDK 1 could have a role in the pathogenesis of subset of breast cancers and contribution in their carcinogenesis.

Small-molecule anticancer agents kill cancer cells by harnessing reactive oxygen species in an iron-dependent manner
...Show More Authors

In the course of generating a library of open-chain epothilones, we discovered a new class of small molecule anticancer agents that has no effect on tubulin but instead kills selected cancer cell lines by harnessing reactive oxygen species in an iron-dependent manner.

BRCA1 is Overexpressed in Breast Cancer Cell Lines and is Negatively Regulated by E2F6 in Normal but not Cancerous Breast Cells
...Show More Authors

This study focused on the expression and regulation of BRCA1 in breast cancer cell lines compared to normal breast. BRCA1 transcript levels were assessed by real time quantitative polymerase chain reaction (RT-qPCR) in the cancer cell lines. Our data show overexpression of BRCA1 mRNA level in all the studied breast cancer cell lines: MCF-7, T47D, MDA-MB-231 and MDA-MB-468 along with Jurkat, leukemia T-lymphocyte, the positive control, relative to normal breast tissue. To investigate whether a positive or negative correlation exists between BRCA1 and the transcription factor E2F6, three different si-RNA specific for E2F6 were used to transfect the normal and cancerous breast cell lines. Interestingly, strong negative relationship was found b

Association of tumor necrosis factor-alpha promoter region gene polymorphism at positions -308G/A, -857C/T, and -863C/A with etanercept response in Iraqi rheumatoid arthritis patients
...Show More Authors

Objectives: This study aims to evaluate the association between polymorphisms in the promoter region of the tumor necrosis factor-alpha (TNF-α) gene at locations -308G/A, -857C/T, and -863C/A with the tendency of being non-responder to etanercept.

Patients and methods: Between October 2020 and August 2021, a total of 80 patients (10 males, 70 females; mean age: 50 years; range, 30 to 72 years) with rheumatoid arthritis (RA) receiving etanercept for at least six months were included. The patients were divided into two groups responders and non-responders, based on their response after six months of continuous treatment. Following polymerase chain reac

Status of CHADS2 and CHA2DS2-VASc Scores in Predicting Risk of Stroke and its Prevention in Iraqi Patients with Atrial Fibrillation
...Show More Authors

Atrial fibrillation is associates with elevated risk of stroke. The simplest stroke risk assessment schemes are CHADS2 and CHA2DS2-VASc score. Aspirin and oral anticoagulants are recommended for stroke prevention in such patients.

The aim of this study was to  assess status of CHADS2 and CHA2DS2-VASc scores in Iraqi atrial fibrillation patients and to report current status of stroke prevention in these patients with either warfarin or aspirin in relation to these scores.

This prospective cross-sectional study was carried out at Tikrit, Samarra, Sharqat, Baquba, and AL-Numaan hospitals from July 2017 to October 2017. CHADS2
