1Zainab T. Hussein, 2Ismail A. Abdul-Hassan — Wed, 27 Nov 2024 00:00:00 +0100

Recurrent spontaneous abortion (RSA) is characterized by the occurrence of two or more spontaneous pregnancy losses before reaching the midpoint of gestation. Oxidative stress assumes a central role in the development of RSA, serving as a key factor in its pathogenesis. The objective of this study is to explore the link between the L55M polymorphisms found in the PON1 gene, which codes for an antioxidant enzyme, and the susceptibility to RSA.Paraoxonase 1 (PON1) is a critical enzyme in the body's antioxidant defense system, safeguarding cells against damage caused by reactive oxygen species. The most prevalent PON1 polymorphism, L55M (rs854560), is known to influence PON1 activity. In this research, blood samples were collected from two groups: 50 women with a history of RSA and 50 women who were apparently healthy. Following DNA extraction, Restriction Fragment Length Polymorphism (RFLP) analysis was employed in conjunction with PCR amplification to identify single-nucleotide polymorphisms (SNPs) and ELISA for determining PON1 activity, total antioxidant capacity (TAC) and HDL concentration in serum. The result of this study showed decreasing in PON1 activity (8.15 ± 2.15 versus 9.66 ± 3.75 , respectively) and TAC (2.80 ± 0.10 versus 3.53 ± 1.52, respectively) in patients with RSA than apparently healthy women, while HDL concentrations higher in women with RSA than apparently healthy women (12.68 ± 5.53versus 9.01 ± 5.30, respectively) which are lead to increase oxidative stress and related with RSA. The genotype results showed that the percentage of TA genotype was in women with recurrent spontaneous abortion significantly higher than that of apparently healthy women (60% versus 32 %, respectively, OR=3.5) and this represent a risk factor for recurrent spontaneous abortion incidence. Also, the percentage of AA genotype in women with recurrent spontaneous abortion was higher than that of apparently healthy women but non-significant (12% and 4% 68%, respectively). The values of allele frequency for T allele were 0.8 and 0.6 for apparently healthy women and women with recurrent spontaneous abortion, respectively. The values of allele frequency for A allele were 0.2 and 0.4 for apparently healthy women and women with recurrent spontaneous abortion, respectively. It was concluded the heterozygous TA genotype is related with the risk of RSA and the minor allele (A allele) increased in women with RSA.

Breast carcinoma is the most prevalent cancer-related cause of death in women, and metastasis is the main factor in morbidity. The aim of the study level of TGF-B1 between the age groups. The total number of new cases of cancer in Iraq during the year 2019 was 35,864. Transforming growth factor (TGF) is a multifunctional cytokine whose abnormal expression is linked to cancer development and metastasis. The tumor growth factor TGF-β is a major component of epithelial–mesenchymal transition (EMT), immune evasion, and metastasis during cancer progression. It is produced by a variety of cells within the tumor microenvironment (TME), and it is responsible for regulating the activity of cells in this milieu. TGF-b is also central to immune suppression within the tumor microenvironment, and recent studies have revealed roles in tumor immune evasion and poor responses to cancer immunotherapy. Then, focusing on cancer, we discuss the roles of TGF-b signaling in distinct immune cell types and how this knowledge is being leveraged to unleash the immune system against the tumor. The aim of this study to investigate the role of TGF-B1 in Breast Cancer risk Method: measure the protein level by ELISA Sandwich method. It was concluded that found significant increase in cancer patients compare with controls, according to age group that was no- significant association and the result show significant increase in metastasis patients compare with non-metastasis group.

1Sawsan A. Yusif, 1Rafid A. Abdulkareem — Wed, 27 Nov 2024 00:00:00 +0100

Ulcerative colitis is a chronic inflammatory bowel disease. Thiopurine methyltransferase (TPMT) is an enzyme that metabolizes a class of drugs called thiopurines. The aim of this study was to examine the impact of a polymorphism (rs2842934) in TPMT gene on TPMT level. Genotyping for TPMT gene (rs2842934) polymorphism was determined by the tetra-primer amplification refractory mutation system-polymerase chain reaction (TARMS-PCR). Serum TPMT level was estimated by ELIZA Technique .The TPMT gene (rs2842934) polymorphism demonstrated a significant association with UC risk. The highest prevalence of UC was seen among patients who had heterozygous GA genotype [Odd Ratio (OR): 17.51; 95% Confidence Interval (CI): (6.109-50.199); P-value <0.001]. The homozygous genotype (GG) showed the lowest risk with only (8%) in UC patients compared to the controls (72.5%) [OR: (0.03); 95%CI. (0.011-0.100); P-value < 0.001]. The highest mean TPMT enzyme level was ±196 pg/mL in UC patients who were homozygous for A allele compared to ±0.50 pg/mL in controls; P-value <0.001. Conclusions: The TPMT gene (rs2842934) polymorphism showed that the G allele was beneficial for protection from UC. In contrast, the “A” allele of rs6721961 significantly increases susceptibility to UC.

1Luma Y. Aldouri, 1Mohammed I. Nader, 2Mohammed H. Munshed Al-Osami — Wed, 27 Nov 2024 00:00:00 +0100

MicroRNAs (miRNAs), a type of small non-coding RNAs, play a crucial role in controlling post-transcriptional gene expression, suggesting their potential involvement in autoimmune disorders. The objective of the current study was to assess the expression levels of miR-146a as potential indicators for diagnosing rheumatoid arthritis (RA) and to examine their correlation with disease activity. A total of one hundred blood samples divided into 50 RA patients and 50 healthy individuals were obtained. The medical histories of all participants were collected, and they were provided with a comprehensive clinicopathological assessment. Disease activity for the group of patients was evaluated using the Disease Activity Score 28 (DAS28). The RNA content of blood samples was extracted, followed by cDNA synthesis. Subsequently, the levels of miR-146a transcripts were measured using Real-time PCR. Significant statistical differences were seen between patients and healthy controls in terms of miR-146a relative expression, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and anti-cyclic citrullinated peptide (anti-CCP) levels (p < 0.01). The miR-146a expression level, with a fold change of 4.87, exhibited a substantial upregulation in the whole blood samples obtained from patients diagnosed with RA compared to those obtained from healthy controls. Furthermore, a positive correlation was seen between the miR-146a expression level and the levels of ESR, DAS28, CRP, and anti-CCP in the RA patients. In diagnosing RA, MiR-146a had superior diagnostic capabilities, exhibiting the most significant levels of sensitivity and specificity at 74% and 87%, respectively. This was further supported by an area under the curve (AUC) value of 0.90, obtained at a cut-off value of P2.55. In comparison, the diagnostic performance of anti-CCP was not as favorable. The diagnostic test demonstrated a sensitivity of 52%, specificity of 100%, and AUC of 0.81 when using a cut-off value of P 122.5U/ml. In summary, the increased expression of miR-146a in the entirety of blood samples from individuals with RA may serve as a possible indicator of disease activity and severity in those with established RA.

The second leading cause of death for women is breast cancer. The disease has been successfully managed by conventional therapies. The aim of study to found novel strategies, such as oncolytic virotherapy, were required to fight it. x given by ICCMGR, was cultivated using chicken eggs from commercial hatcheries in Al-Hur area, a suburb of Holy Kerbala province. Propagated NDV induced considerable hemorrhaging in infected embryos compared to unaffected control embryos and destroyed all embryos within 48 hours. For additional testing, allantoic fluid containing the virus was collected, purified, and kept at -20°C. Hemagglutination (HA) assay was employed to quantify the NDV titer which show positive findings as a typical haemagglutination mesh pattern of chicken red blood cells at 2⁸, or 256 HAU. Using Vero cells and Flint's algorithm to calculate the Tissue Culture Infection Dose 50 (TCID50) test, the viral dilution and syncytia growth in the seeded wells were linked, and the result was found to be 3.5 * 10⁶ viral unit/ml. The multiplicity of the viral infection (MOI) 1,2 and 3 was prepared and tested on Amj-13 and MCF-7 of which cell viability and growth inhibition rate using MTT assay was examined. Results of Optical Density (OD) and Inhibition Rate Growth Percentage (IR%) were calculated using Statistical Analysis System (SAS) to determine Least Square Means (LSM) to compare the significance difference between the mean values at p ≤ 0.05. There were proportional significant increases, (P ≤ 0.05), in inhibitory rate of both cancer cell lines treated with all concentrations of NDV alone compared with control of which the highest inhibitory rate was recorded at concentration (3 MOI) suggesting the more viral particles, the greatest cytotoxicity caused that reached 73.14% and 67.7 % respectively. The cytopathic effects (CPE) caused to cell lines due to the exposure NDV was observed under inverted microscope. Cells suffer morphological changes including granulation and shrinkage of cytoplasm, which lead eventually to separation and floating of the infected cells in the culture media, after 72 hrs. large round empty spaces were so apparent. These observations were not detected in control cell culture within the same time of examination of infected cells. The results were concluded promising results in not just eradicating cancerous cells, but as potential cancer vaccine.
