Background: The human CD19 (Cluster Differentiation) antigen is a 95 kd transmembrane glycoprotein belonging to the immunoglobulin superfamily. CD19 gene located on the short arm of chromosome 16p11.2 (P: petit). CD19 is a member of the Ig immunoglobulin superfamily expressed on the surface of B lymphocytes, and may play a pivotal role in B-cell differentiation and activation. Research suggests that mutations in a gene CD19 leads to a lack of expression of CD19 membrane and result in an antibody deficiency syndrome.
Objective: The aim of this work is to study the mutations in Exon 2 CD19gene in leukemia patients in Baghdad/Iraq.
Patients and Methods: This cross sectional study was performed in the National Center of Hematological Diseases/Al Mustanisyria University. Blood samples were collected from 50 leukemia patients including (25 acute lymphocyte leukemia ALL and 25 chronic lymphocyte leukemia CLL) and 50 samples of apparently healthy individuals. DNA was isolated and the CD19 gene was amplified by using specific primers for exon2 of this gene. The nucleotide sequences of CD19 gene was according to Macro gene company, USA. Analysis was done using BLAST program which is available online at (http:// www.ncbi.nlm.nih.gov) and BioEdit program.
Results: The DNA sequencing results of flank sense of CD19 gene from healthy individual was found to be compatible 100% with wild type of Homo sapiens from the Gene Bank, while 99% compatibility was found for that gene of all ALL and CLL patients with wild type of gene. The difference was attributed to insertion of 1900 C nucleotide in position +48 of exon 2 of CD19 gene resulted in the replacement of a serine (TCC) residue into isoluseine (ATC), and deletion 1904 C in position + 49 of exon 2. This mutation resulted in change of codon from GCA to GCC but there was no changes in the amino acid (Alanine to Alanine). The second mutation (Deletion nucleotide) amended the first mutation effect (Insertion nucleotide) and did not
lead to a change of all the amino acid sequence (framshift). The results showed that the incidence of insertion and deletion mutation at position +48 and +49 in exon 2 of CD19 gene and leukemia was highly significant (X2 = 15.75, P<0.01).
Conclusion: This study suggests that the ploymrphism in exon 2 of the CD19 gene is strongly associated with leukemia patient of Baghdad population.
Background: Diabetic mellitus (DM) is a collection of metabolic disorder identified by hyperglycemia. The heterogeneous etiology includes defects either in insulin secretion, or in insulin action, or the both. In addition to the distraction in carbohydrate, fat and protein metabolism. Inflammatory reaction that caused by many pro-inflammatory cytokines play a central role in the pathogenicity of T2DM, these cytokines can enhance insulin resistance which led to impaired glucose homeostasis. Subjects: The study included 75 patients (38 males and 37 females) suffering from T2DM with age mean ± SE 52.30 ± 1.60, and 70 individuals as healthy controls (35 males and 35 females) with age mean ± SE 48.88 ± 0.64.

Show MoreBackground: According to several animal and human studies, Vitamin D appears to play a substantial role in the development of diabetic nephropathy, However, the possibility of vitamin D's Reno protective impact and influence on the reversal of already-existing renal damage remains speculative. Vitamin D deficiency and insufficiency are ubiquitous worldwide and have been linked to a variety of pathophysiological conditions, including diabetes, allergies, autoimmune illnesses, pregnancy difficulties, and, more recently, worse COVID-19 clinical outcomes. From a translational perspective, the goal of this review is to look into the potential function of vitamin D in the development of diabetic kidney diseases

Breast cancer is the most prevalent malignancy among women worldwide, in Iraq it ranks the first among the population and the leading cause of cancer related female mortality. This study is designed to investigate the correlations between serum and tissue markers in order to clarify their role in progression or regression breast cancer. Tumor Markers are groups of substances, mainly proteins, produced from cancer cell or from other cells in the body in response to tumor. The study was carried out from April 2018 to April 2019 with total number of 60 breast cancer women. The blood samples were collected from breast cancer women in postoperative and pretherapeutic who attended teaching oncology hospital of the medical city in Baghdad and

It is difficult to adapt treatment to each patient's risk level because there are currently few clinical tests and no molecular diagnostics that may predict a patient's clock for the advancement of CML at the time of chronic phase diagnosis. Biomarkers that can differentiate people based on the outcome at diagnosis are needed for blast crisis prevention and response improvement. Objective: This study is an effort to exploit the SLC25A3 gene as a potential biomarker for CML. Methods: RT-qPCR was applied to assess the expression levels of the SLC25A3 gene. Results: In comparison to the mean ΔCt of the control group, which was found to b

The neutrophil gelatinase Associated lippocallin (NGAL) is an ubiquitous protein consist of 178 amino acid. NGAL can be identified in plasma and urine starting 2- 4 hours after a kidney injury resulting changes in glomerular filtration and tubular reabsorption and with increased secretion in tubular epithelial cells.
Objective: This study aimed to evaluate the role of serum Neutrophil Gelatinse Associated Lipocallin (NGAL) in early detection nephropathy.

The purified frog skin peptides were tested on leukemic patients lymphocytes, which revealed effects of cytotoxicity. Four frogs (Rana ridibunda) were stimulated by single intra-peritoneal injection of norepinephrine-HCl . Five different peptides;1(18) A, 2(19) L, 3(20) I,4(21) E and 5(22) Y were isolated and quantified. The peptide 3(20)I had 5.87% of hemolysis, while healthy human lymphocytes cytotoxic activity was for 2(19)L with inhibition( -10.4%).All peptides were subjected to polyacrylamide gel electrophoresis. The results revealed peptides 1(18)A, 2(19)L, 3(20)I which appeared as low as 10 KDa marker. Theoretically, the whole polypeptide had a molecular weight 7488.61 Dalt
