Abstract
Cancer remains a worldwide healthcare undertaking, demanding continual innovation in anticancer drug development due to frequent drug resistance and adverse effects associated with existing therapies. The benzothiazole compounds, particularly 2-aminobenzothiazole derivatives, have attracted interest for their versatility in generating novel anticancer agents. This study explores the synthesis, and anticancer evaluation of new pyrimidine-based 2-aminobenzothiazole derivatives. A range of synthetic methods have been developed based on the reaction of 2-benzothaizolyl guanidine with various reagents such as α,β-unsaturated carbonyl, 2-cyano-three-(dimethylamino)-N-acrylamide, β-diketones, β-keto esters, and S,S ketene dithioacetals. Human tumour cell lines such as HepG2, HCT116, and MCF7 were used in in vitro cytotoxicity studies, and the results showed that several of the synthesized compounds were more potent than the standard drug, 5-fluorouracil, in terms of cell viability% with low IC50. Furthermore, the computed drug likeness and ADMET properties of the most potent synthesized compounds suggest their potential as promising candidates for further development, with favorable bioavailability and pharmacokinetic profiles.

Abstract
MiRNA 200-c-3p has varying functions in different tumor types, whether tumor suppression or promotion. Comprehensive assessment of its function in non-small cell lung cancer (NSCLC) together with its effect on antitumor immune response have not been declared before. We aimed to explore the effect of replacement and suppression of miRNA 200-c-3p on non-small cell lung cancer and its impact on immune checkpoint function and subsequently antitumor immunity. MiRNA 200-c-3p mimic/inhibitor was transfected into the A549 cells. A 549 non-small cell lung cancer cells viability was done by trypan blue staining and 3-(4, 5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay. Flowcytometric analysis was done for apoptosis detection. Real-time reverse transcription-quantitative polymerase chain reaction (RT-qPCR) and western blot analysis were used to study its effect on relative gene expression and relative protein level of programmed cell death ligand 1 (PD-L1). Finally, co-culture with isolated and activated T cells was performed. Multiple comparisons were performed using one-way analysis of variance (ANOVA) followed by Tukey's multiple-comparison test. Decreased cell viability, increased apoptosis, reduced PD-L1 relative gene expression and its relative protein level, together with enhanced T cell cytotoxicity towards tumor cells were detected after miRNA 200-c-3p mimic transfection of A549 NSCLC cell line. However, these results were reversed in miRNA 200-c-3p suppression. MiRNA 200-c-3p had a tumor suppressive effect in non-small cell lung cancer cells which might be through down regulation of PD-L1 relative gene expression, and it may be used as a new target to improve immune checkpoint dysfunction.

Abstract
Infection is the second most common cause of mortality among end-stage kidney disease (ESKD) patients. Uremic toxins are the main cause of impaired immune response among ESKD patients. Klotho gene, the anti-aging gene, encodes the transmembrane alpha klotho (αKL) protein which acts as an obligate coreceptor for fibroblast growth factor 23 (FGF23). Klotho protein may play a role in immune cell functions, particularly in anti-inflammatory response; however, its role is still incompletely understood. In the present study, we aimed to measure αKL protein expression on peripheral blood lymphocytes (PBLs) among hemodialysis (HD) patients, and we assumed that decreased αKL expression on PBLs may contribute to the impaired immunity among HD patients. This case-control study included 20 ESKD patients on regular hemodialysis for more than 3 months. Their ages ranged from 24 to 69 years. Patients with primary immunodeficiencies, those on systemic immunosuppressive drugs, those with ongoing infections or who had recently recovered from infections, and those with malignancies on active treatment were excluded. A control group of 20 normal subjects of comparable age and gender were also included. We compared αKL protein expression on PBLs by flow cytometry between both groups. Significant reductions in percentages of αKL protein expression on B lymphocytes (CD19), T lymphocytes (CD3), and natural killer cells (CD56) were observed among HD patients compared to controls. We also noticed a significant reduction in the percentages of natural killer cells among HD patients. The present study suggests that decreased αKL expression on PBLs may contribute to the immunocompromised status among HD patients, highlighting the importance of understanding the exact function of αKL protein on immune cells. This may offer a future diagnostic and therapeutic tool to improve the immune response among HD patients.

Abstract
The study aimed to assess the diagnostic and prognostic value of 3 specific microRNAs (miRNAs) in early-onset neonatal sepsis (NS). We examined miR-1, miR-124, and miR-34a in 70 NS patients upon admission and compared them to 70 healthy controls by RT-PCR. The main finding of the study was the difference in miRNA expression levels between NS patients and controls. Higher expression levels of miR-1 and miR-124 were significantly associated with NS, while miR-34a expression was reduced. Among the studied miRNAs, miR-34a exhibited the highest specificity (97%) as a confirmatory test for NS. In the multivariate model, miR-1 and miR-124 were found to be significant predictors of disease progression or mortality. Overall, the study suggests that miR-1, miR-124, and miR-34a could serve as potential biomarkers for diagnosing and predicting outcomes in early-onset NS.

Abstract
The challenge of rapidly diagnosing myocardial ischemia in unstable angina (UA) patients presenting to the Emergency Department (ED) is due to a lack of sensitive blood biomarkers. This has prompted an investigation into microRNAs (miRNAs) related to cardiac-derived Nourin for potential diagnostic application. The Nourin protein is rapidly expressed in patients with acute coronary syndrome (ACS) (UA and acute myocardial infarction (AMI)). MicroRNAs regulate gene expression through mRNA binding and, thus, may represent potential biomarkers. We initially identified miR-137 and miR-106b and conducted a clinical validation, which demonstrated that they were highly upregulated in ACS patients, but not in healthy subjects and non-ACS controls. Using integrated comprehensive bioinformatics analysis, the present study confirms that the Nourin protein targets miR-137 and miR-106b, which are linked to myocardial ischemia and inflammation associated with ACS. Molecular docking demonstrated robust interactions between the Nourin protein and miR137/hsa-miR-106b, involving hydrogen bonds and hydrophobic interactions, with -10 kcal/mol binding energy. I-TASSER generated Nourin analogs, with the top 10 chosen for structural insights. Antigenic regions and MHCII epitopes within the Nourin SPGADGNGGEAMPGG sequence showed strong binding to HLA-DR/DQ alleles. The Cytoscape network revealed interactions of -miR137/hsa-miR--106b and Phosphatase and tensin homolog (PTEN) in myocardial ischemia. RNA Composer predicted the secondary structure of miR-106b. Schrödinger software identified key Nourin-RNA interactions critical for complex stability. The study identifies miR-137 and miR-106b as potential ACS diagnostic and therapeutic targets. This research underscores the potential of miRNAs targeting Nourin for precision ACS intervention. The analysis leverages RNA Composer, Schrödinger, and I-TASSER tools to explore interactions and structural insights. Robust Nourin-miRNA interactions are established, bolstering the case for miRNA-based interventions in ischemic injury. In conclusion, the study contributes to UA and AMI diagnosis strategies through bioinformatics-guided exploration of Nourin-targeting miRNAs. Supported by comprehensive molecular analysis, the hypoxia-induced miR-137 for cell apoptosis (a marker of cell damage) and the inflammation-induced miR-106b (a marker of inflammation) confirmed their potential clinical use as diagnostic biomarkers. This research reinforces the growing role of miR-137/hsa-miR-106b in the early diagnosis of myocardial ischemia in unstable angina patients.

Abstract
BACKGROUND Trastuzumab is an effective therapeutic approach for HER2-positive metastatic breast cancer (BC). However, a considerable number of patients develop resistance along the course of the disease. PTEN rs701848 polymorphisms are associated with an increased risk of developing cancer and have a potential role in predicting drug resistance. OBJECTIVE We studied the significance of PTEN rs701848 variants as significant predictors for trastuzumab resistance in HER2-positive metastatic BC patients. Therefore, considering their value in predicting clinical outcomes. MATERIALS AND METHODS This case-control study was conducted among female patients with HER2-positive metastatic breast cancer who underwent Trastuzumab therapy during the period from March 2017 to December 2020. PTEN rs701848 genotypes were analyzed in 160 HER2-positive metastatic breast cancer who received Trastuzumab therapy and clinically monitored for therapeutic response. RESULTS PTEN rs701848 is deemed a significant predictor of Trastuzumab resistance and an independent prognostic factor of progression-free survival (PPFS). In particular, the C allele is associated with increased risk for Trastuzumab resistance and shorter PFS as compared to the homozygous TT genotype. CONCLUSION PTEN rs701848 is significant predictor of trastuzumab resistance. Therefore, their value in predicting clinical outcomes is recommended.

Abstract
T-cell Acute Lymphoblastic Leukemia (T-ALL) accounts for around 10-15% of all lymphoblastic leukemia in children. Previous studies have proven that dysregulation of Leukemia-induced non-coding activator RNA-1 (LUNAR1) expression promotes T-ALL cell growth by enhancing the NOTCH1/IGF-1R signaling pathway. We aimed to investigate the prognostic value of LUNAR1 in pediatric T-ALL, in addition, to find out its association with NOTCH1 and IGF-1R. The LUNAR1, NOTCH1, and IGF-IR gene expression were measured in peripheral blood (PB) samples of l85 children with T-ALL and forty non-leukemic samples as a control group. Cox regression analysis revealed that overexpression of LUNAR1, NOTCH1, and IGF-IR was significantly correlated with poor prognosis, short overall survival, and progression-free survival. We concluded that LUNAR1 could serve as an independent prognostic biomarker for T-ALL in children.

Abstract
Background The current pandemic of COVID-19 impacted the psychological wellbeing of populations globally. Objectives We aimed to examine the extent and identify factors associated with psychological distress, fear of COVID-19 and coping. Methods We conducted a cross-sectional study across 17 countries during Jun-2020 to Jan-2021. Levels of psychological distress (Kessler Psychological Distress Scale), fear of COVID-19 (Fear of COVID-19 Scale), and coping (Brief Resilient Coping Scale) were assessed. Results A total of 8,559 people participated; mean age (±SD) was 33(±13) years, 64% were females and 40% self-identified as frontline workers. More than two-thirds (69%) experienced moderate-to-very high levels of psychological distress, which was 46% in Thailand and 91% in Egypt. A quarter (24%) had high levels of fear of COVID-19, which was as low as 9% in Libya and as high as 38% in Bangladesh. More than half (57%) exhibited medium to high resilient coping; the lowest prevalence (3%) was reported in Australia and the highest (72%) in Syria. Being female (AOR 1.31 [95% CIs 1.09-1.57]), perceived distress due to change of employment status (1.56 [1.29-1.90]), comorbidity with mental health conditions (3.02 [1.20-7.60]) were associated with higher levels of psychological distress and fear. Doctors had higher psychological distress (1.43 [1.04-1.97]), but low levels of fear of COVID-19 (0.55 [0.41-0.76]); nurses had medium to high resilient coping (1.30 [1.03-1.65]). Conclusions The extent of psychological distress, fear of COVID-19 and coping varied by country; however, we identified few higher risk groups who were more vulnerable than others. There is an urgent need to prioritise health and well-being of those people through well-designed intervention that may need to be tailored to meet country specific requirements.

Abstract
Persistent pulmonary hypertension of the new-borns (PPHN) is one of the main etiologies of morbidity as well as mortality in neonates. Previous studies found that genetic polymorphisms in urea cycle enzymes are associated with PPHN. Few of the genetic polymorphisms in neonates have been recognized with PPHN. We aimed to find out the prevalence of the CPS-I gene polymorphism and to correlate the genotype with the serum nitric oxide (NO) levels in Egyptian neonates with idiopathic PPHN. We included neonates diagnosed with PPH (n = 150) while the control group included healthy neonates with matched age and sex (n = 100). The CPS-I gene polymorphism: A/C, trans-version substitution, rs4399666 genotype was identified using TaqMan-based quantitative PCR. The results revealed that the CPS-I A/C rs4399666 gene polymorphism and lower serum NO levels were significantly associated with idiopathic PPHN in neonates. In addition, serum NO level was significantly associated with an rs4366999 A/C variant gene in idiopathic PPHN (p = 0.001). Univariable regression analysis demonstrated that there was a significant association between CPS-I A/C rs4399666 CC and increased risk of PPHN (odd ratio, 95% CI of 1.8 (0.78 to 1.75), p-value = 0.04).Conclusion: We concluded that mutant CPS-I A/C rs4399666 minor variant especially the homozygous CC genotype is frequently distributed among the PPHN group. This demonstrates that the presence of mutant CPS-I rs4399666 does not necessarily predispose to the development of PPHN in neonates, but nonetheless, if the C allele is inherited in the homozygous CC genotype, it is associated with a higher risk of PPHN. What is Known: • Prior studies found that polymorphisms in urea cycle enzyme genes are associated with PPHN. • Association between CPS-1 gene polymorphisms is significantly associated with PPHN. What is New: • The prevalence of CPS-1, A/C trans-version substitution, rs4399666 gene polymorphism in Egyptian neonates presented with idiopathic PPHN. • Mutant CPS-I A/C rs4399666 especially the homozygous CC genotype is more frequently distributed among PPHN, and it is significantly associated with low serum nitric oxide level.

Abstract
Abstract
Background: The current pandemic of COVID-19 impacted the psychological wellbeing of populations globally. Objectives: We aimed to examine the extent and identify associated factors of psychological distress, fear of COVID-19, and coping.Methods: We conducted a cross-sectional study across 17 countries during Jun-2020 to Jan-2021. Levels of psychological distress (Kessler Psychological Distress Scale), fear of COVID-19 (Fear of COVID-19 Scale), and coping (Brief Resilient Coping Scale) were assessed. Results: A total of 8,559 people participated; mean age (±SD) was 33(±13) years, 64% were females and 40% self-identified as frontline workers. More than two-thirds (69%) experienced moderate-to-very high levels of psychological distress, which was 46% in Thailand and 91% in Egypt. A quarter (24%) had high levels of fear of COVID-19, which was as low as 9% in Libya and as high as 38% in Bangladesh. More than half (57%) exhibited medium to high resilient coping; the lowest prevalence (3%) was reported in Australia and the highest (72%) in Syria. Being female (AOR 1.31 [95% CIs 1.09-1.57]), perceived distress due to change of employment status (1.56 [1.29-1.90]), comorbidity with mental health conditions (3.02 [1.20-7.60]) were associated with higher levels of psychological distress and fear. Doctors had higher psychological distress (1.43 [1.04-1.97]), but low levels of fear of COVID-19 (0.55 [0.41-0.76]); nurses had medium to high resilient coping (1.30 [1.03-1.65]). Conclusions: The extent of psychological distress, fear of COVID and coping varied by country; however, some groups were more vulnerable than others. There is an urgent need to prioritise health and well-being of these people through well-designed intervention that may need to be tailored to meet country specific requirements.

Abstract
Background: Although cardiovascular imaging techniques are widely used to diagnose myocardial ischemia in patients with suspected stable coronary artery disease (CAD), they have limitations related to lack of specificity, sensitivity and “late” diagnosis. Additionally, the absence of a simple laboratory test that can detect myocardial ischemia in CAD patients, has led to many patients being first diagnosed at the time of the development of myocardial infarction. Nourin is an early blood-based biomarker rapidly released within five minutes by “reversible” ischemic myocardium before progressing to necrosis. Recently, we demonstrated that the Nourin-dependent miR-137 (marker of cell damage) and miR-106b-5p (marker of inflammation) can diagnose myocardial ischemia in patients with unstable angina (UA) and also stratify severity of ischemia, with higher expression in acute ST-segment elevation myocardial infarction (STEMI) patients compared to UA patients. Minimal baseline-gene expression levels of Nourin miRNAs were detected in healthy subjects. Objectives: To determine: (1) whether Nourin miRNAs are elevated in chest pain patients with myocardial ischemia suspected of CAD, who also underwent dobutamine stress echocardiography (DSE) or ECG/Treadmill stress test, and (2) whether the elevated levels of serum Nourin miRNAs correlate with results of ECHO/ECG stress test in diagnosing CAD patients. Methods: Serum gene expression levels of miR-137, miR-106b-5p and their corresponding molecular pathway network were measured blindly in 70 enrolled subjects using quantitative real time PCR (qPCR). Blood samples were collected from: (1) patients with chest pain suspected of myocardial ischemia (n = 38) both immediately “pre-stress test” and “post-stress test” 30 min. after test termination; (2) patients with acute STEMI (n = 16) functioned as our positive control; and (3) healthy volunteers (n = 16) who, also, exercised on ECG/Treadmill stress test for Nourin baseline-gene expression levels. Results: (1) strong correlation was observed between Nourin miRNAs serum expression levels and results obtained from ECHO/ECG stress test in diagnosing myocardial ischemia in CAD patients; (2) positive “post-stress test” patients with CAD diagnosis showed upregulation of miR-137 by 572-fold and miR-106b-5p by 122-fold, when compared to negative “post-stress test” patients (p < 0.001); (3) similarly, positive “pre-stress test” CAD patients showed upregulation of miR-137 by 1198-fold and miR-106b-5p by 114-fold, when compared to negative “pre-stress test” patients (p < 0.001); and (4) healthy subjects had minimal baseline-gene expressions of Nourin miRNAs. Conclusions: Nourin-dependent miR-137 and miR-106b-5p are promising novel blood-based biomarkers for early diagnosis of myocardial ischemia in chest pain patients suspected of CAD in outpatient clinics. Early identification of CAD patients, while patients are in the stable state before progressing to infarction, is key to providing crucial diagnostic steps and therapy to limit adverse cardiac events, improve patients’ health outcome and save lives.

Abstract
BACKGROUND Currently, no blood biomarkers exist that can diagnose unstable angina (UA) patients. Nourin is an early inflammatory mediator rapidly released within 5 min by reversible ischemic myocardium, and if ischemia persists, it is also released by necrosis. Nourin is elevated in acute coronary syndrome (ACS) patients but not in symptomatic noncardiac and healthy subjects. Recently, circulating microRNAs (miRNAs) have been established as markers of disease, including cardiac injury and inflammation. OBJECTIVES To profile and validate the potential diagnostic value of Nourin-dependent miR-137 (marker of cell damage) and miR-106b-5p (marker of inflammation) as early biomarkers in suspected UA patients and to investigate the association of their target and regulating genes. METHODS Using Nourin amino acid sequence, an integrated bioinformatics analysis was conducted. Analysis indicated that Nourin is a direct target for miR-137 and miR-106b-5p in myocardial ischemic injury. Two linked molecular networks of lncRNA/miRNAs/mRNAs were also retrieved, including CTB89H12.4/miR-137/FTHL-17 and CTB89H12.4/miR-106b-5p/ANAPC11. Gene expression profiling was assessed in serum samples collected at presentation to an emergency department (ED) from: (1) UA patients (n = 30) (confirmed by invasive coronary angiography with stenosis greater than 50% and troponin level below the clinical decision limit); (2) patients with acute ST elevation myocardial infarction (STEMI) (n = 16) (confirmed by persistent ST-segment changes and elevated troponin level); and 3) healthy subjects (n = 16). RESULTS Gene expression profiles showed that miR-137 and miR-106b-5p were significantly upregulated by 1382-fold and 192-fold in UA compared to healthy, and by 2.5-fold and 4.6-fold in STEMI compared to UA, respectively. Healthy subjects showed minimal expression profile. Receiver operator characteristics (ROC) analysis revealed that the two miRNAs were sensitive and specific biomarkers for assessment of UA and STEMI patients. Additionally, Spearman's correlation analysis revealed a significant association of miRNAs with the associated mRNA targets and the regulating lncRNA. CONCLUSIONS Nourin-dependent gene expression of miR-137 and miR-106b-5p are novel blood-based biomarkers that can diagnose UA and STEMI patients at presentation and stratify severity of myocardial ischemia, with higher expression in STEMI compared to UA. Early diagnosis of suspected UA patients using the novel Nourin biomarkers is key for initiating guideline-based therapy that improves patients' health outcomes.

Abstract
BACKGROUND Multiple Myeloma (MM) is a heterogeneous, hematological neoplasm that accounts 2% of all cancers. Although, autologous stem cell transplantation and chemotherapy are currently the most effective therapy, it carries a notable hazards, in addition for being non curative. Recently, the Clustered Regular Interspaced Short Palindromic Repeats (CRISPR-cas9) has been successfully tried at the experimental level, for the treatment of several hematological malignancies. OBJECTIVES We aimed to investigate the in-vitro effect of CRISPR-cas9-mediated knock-out of V-set pre B-cell surrogate light chain 1"VPREB1" gene on the malignant proliferation of primary cultured myeloma cells. METHODS Bioinformatics' analysis was performed to explore the gene expression profile of MM, and the VPREB1 gene was selected as a target gene for this study. We knocked-out the VPREB1 gene in primary cultured myeloma cells using CRISPR-cas9, the VPREB1 gene editing efficacy was verified by determining VPREB1 gene expression at both the mRNA and protein levels by qPCR and immunofluorescence, respectively. Furthermore, the cytotoxic effect on primary myeloma cells proliferation was evaluated using cytotoxicity assay. RESULTS There was a statistically significant reduction of both VPREB1 mRNA and protein expression levels (p<0.01). knock-out of VPREB1 gene in myeloma cell line resulted in a statistically significant reduction of myeloma cell proliferation. CONCLUSION CRISPR-cas9-mediated knock-out of VPREB1 gene is effective for inhibiting the proliferation of primary myeloma cells. This would provide a basis for a promising therapeutic strategy for patients with multiple myeloma.

Abstract
Emerging hepatocellular carcinoma (HCC) has been sequentially reported in chronic hepatitis C virus (HCV) treated with direct-acting antivirals (DAAs). Homeobox transcript antisense RNA (HOTAIR), an oncogene, has been reported to be associated with cancer. We investigated the predictive value of lnc-HOTAIR for HCC surveillance in chronic HCV patients following DAAs therapy. The expression levels of lnc-HOTAIR and ATG-7 genes were measured in 220 with chronic HCV, following a DAAs based therapy for 12 weeks, the patients were followed-up for attentive surveillance of HCC for 12 months after starting DAAs. In terms of lnc-HOTAIR, patients with HCC and high viral load had significantly higher median expression levels of HOTAIR of (68 vs. 24; p = .001) and (94 vs. 52; p = .001), respectively. Moreover, the median expression level of ATG-7 was higher in those who developed HCC (114 vs. 51; p = .001). The expression of lnc-HOTAIR and ATG-7 are significant predictors of the development of HCC in HCV-4 infected patients treated with DAAs, with a cut-off value of 37 and 86, respectively. The increased expression levels of lnc-HOTAIR more than 68 in HCC patients following DAAs were correlated with poorer disease outcomes compared to those with lower expression levels; however, ATG-7 expression levels more than 114 were correlated with worse overall survival but not the progression-free one. We suggest that high expression levels of lnc-HOTAIR could serve as a risk assessment biomarker for HCC before and during DAAs course therapy in Chronic HCV-4 patients, and should be rigorously taken into consideration before DAAs.

Abstract
Objective: To examine the safety and efficacy of hyeprimmunoglobulin therapy on vertical transmission of congenital cytomegalovirus (CCMV).Method: We searched nine databases for studies investigating the effect of Hyperimmunoglobulin among pregnant women with CMV.Results: Of total eight studies, the pooled prevalence of CCMV was 36.5% (95% confidence intervals (CI): 26-49%). There was no evidence that hyperimmunoglobulin is effective against CCMV [odds ratio (OR) (95% (CI)) = 0.53 (0.20-1.42)]. However, analyzing only studies of pregnant women with confirmed primary infection, a significant reduction in the congenital CCMV rates was observed [OR (95% CI) = 0.33 (0.18-0.59)]. Based on the purpose, CCMV prevention was successful with a reduction of the CCMV rates [OR (95% CI) = 0.33 (0.16-0.68)[, while treatment was not]OR (95% CI) = 0.80 (0.04-15.01)]. The most common adverse pregnancy outcome was prematurity, followed by intrauterine growth retardation (IUGR) and termination of pregnancy (TOP), with no significant impact of antenatal hyperimmunoglobulin usage.Conclusion: Our results showed a promising efficacy of hyperimmunoglobulin therapy among pregnant women with confirmed primary infection, which fades away on including secondary infection. This effectiveness was limited to the prevention, not the treatment, of CCMV. More randomized controlled trials are needed to provide concrete evidence.

Abstract
Taking advantage of the cellular immune system is the mainstay of the adoptive cell therapy, to induce recognition and destruction of cancer cells. The impressive demonstration of this principle is chimeric antigen receptor-modified T (CAR-T)-cell therapy, which had a major impact on treating relapsed and refractory hematological malignancies. Despite the great results of the CAR-T-cell therapy, many tumors are still able to avoid immune detection and further elimination, as well as the possible associated adverse events. Herein, we highlighted the recent advances in CAR-T-cell therapy, discussing their applications beneficial functions and side effects in hematological malignancies, illustrating the underlying challenges and opportunities. Furthermore, we provide an overview to overcome different obstacles using potential manufacture and treatment strategies.

Abstract
OBJECTIVES The current study aimed to investigate the potentiality of three lncRNAs "Plasmacytoma variant translocation 1(lnc-PVT1), Taurine upregulated gene type 1(lnc-TUG1) and Maternally expressed gene 3 (lnc-MEG-3)", to predict Cisplatin resistance in ovarian cancer (OC), in addition, to access their prognostic significance. METHODS The expression level of lncRNAs were measured in 100 formalin-fixed paraffin-embedded tissue (FFET) samples of OC patients who were treated by Cisplatin-based chemotherapy using qPCR. RESULTS The results showed that lnc_PVT1 was significantly upregulated by 2.3 folds in Cisplatin resistant tissues, while, lnc-TUG1 and lnc-MEG3 were downregulated by 1.2 and 3 folds, respectively. In addition, the three lncRNAs exhibited high sensitivity and specificity in predicting chemo-resistance and they were negatively associated with OS and progression-free survival (p < 0.001). CONCLUSION The lnc-PVT1, lnc-TUG1, and lnc-MEG3 transcriptome signatures could be used for predicting resistance to Cisplatin in OC patients.

Abstract
BACKGROUND Lnc-IRF2-3 and Lnc-ZNF667-AS1 were recently studied as a positive biomarker for many tumor cells. However, experimental studies found that they are associated with worse outcomes in B-CLL. METHODS A prospective case study was conducted on 135 B-CLL patients that were compared to thirty healthy controls. The patients were followed up for 40 months and quantitative measurements of Lnc-IRF2-3 and Lnc-ZNF667-AS1 were measured and compared between the two groups as well as high-risk and low low-risk B-CLL. RESULTS Lnc-IRF2-3 and Lnc-ZNF667-AS1 had a high specificity (94% and 85%) and sensitivity (85%, 87%), respectively, to differentiate B-CLL from healthy controls. Furthermore, they showed high expression levels in high-risk CLL groups. For survival analysis, there was a negative correlation between overall survival (OS) and progression-free survival (PFS) and both biomarkers. However, it was not evident in multivariate Cox regression analysis; in patients with Lnc-IRF2-3 expression level, >67 had a significant decrease in OS and PFS. However, there is no significant effect for high expression levels of Lnc-ZNF667-AS1 on OS (P = .16) or PFS (P = .48). CONCLUSION The Lnc-IRF2-3 and Lnc-ZNF667-AS1 are promising prognostic biomarkers in B-CLL.

Abstract
Aberrant expression of miRNAs has a link with tumorgenesis and their deregulation is reported in biological fluids of cancer patients. Authors aimed to investigate the diagnostic role of miRNA-17-5p, miR-155 and miRNA-222 in serum samples from breast cancer patients (n = 80), benign breast patients (n = 40) and healthy individuals (n = 30) using quantitative real-time PCR technique. Median levels of investigated markers revealed significant increase in primary breast cancer followed by benign and control groups. Investigated miRNAs reported significant relation with clinical stages and histological grading, while only miRNA-17-5p showed significant relation with hormone receptors. When considering investigated miRNAs as compared to tumor marker, their sensitivities were superior over tumor markers for early diagnosis of breast cancer, detection of early stages and low grades breast cancer patients. In conclusion, detection of the miRNA-17-5p, miR-155 and miRNA-222 expression levels in serum samples is significant promising molecular markers for early breast cancer diagnosis.

Abstract
Hepatitis C virus (HCV) infection is a major public health problem, having a high prevalence in Egypt. Leukemia and lymphoma have been associated with HCV infection. MicroRNA-155 (miR-155) has been reported to play a regulatory role in cancer, inflammation, and immune response to infection. The expression level of miR-155 in HCV viremic patients is controversial; although high miR-155 levels were demonstrated in HCV genotypes 1,2, and 3, low levels of miR-155 were detected in Egyptian patients with HCV genotype 4. Several studies have investigated the correlation between the levels of miRNA-155 and the replication of HCV, others have evaluated miRNA-155 as a prognostic biomarker in different types of cancer. No studies have investigated the impact of miRNA-155 knockdown on HCV pediatric patients associated with childhood acute lymphoblastic leukemia (ALL). We knocked-out the miR_155a in cultured polymorphonuclear cells (PBMCs) obtained from 60 children with ALL; 30 were associated with HCV-4 infection and 30 were HCV negative. The miR_155a, HCV viral load, and cell proliferation werre assessed in treated and untreated cells using TaqMan assay quantitative polymerase chain reaction. We found that miRNA-155 was significantly upregulated by seven folds in the HCV-4 associated ALL group; while being linked to high HCV viral load and leukemic burden, miR_155a knock-out can improve the disease outcome. We conclude that miR-155 is a critical miRNA that is considered a therapeutic target in pediatric HCV leukemic patients.

Abstract
Osteopontin and Pokémon genes may have an important role in the pathogenesis of different malignancies. Osteopontin is a glycoprotein of the extracellular matrix, and Pokémon is a regulator of transcription. Both have been hypothesized to be useful as therapeutic targets or diagnostic markers. We aim to assess the role of both in hepatocellular carcinoma and liver fibrosis due to hepatitis C virus (HCV) infection. We conducted our study on 50 patients and classified them into three groups-Group I: Patients with HCV-related hepatocellular carcinoma (HCC) (n = 30); Group II: Patients with hepatitis C cirrhosis (n = 10); and Group III: Patients with hepatitis C fibrosis (n = 10). We found high levels of Osteopontin and Pokémon gene expression in group I. Osteopontin levels were higher also in patients with liver fibrosis was correlated to high levels of parameters such as alpha fetoprotein and caspase. We conclude that HCC is associated with overexpression of both Osteopontin and Pokémon and that Osteopontin plays a significant role in liver fibrosis due to hepatitis C infection.

Abstract
BACKGROUND Acute lymphoblastic leukemia (ALL) is the most well-known sort of leukemia in children. In spite of favorable survival rates, some patients relapse and achieve a poor outcome. METHODS We analyzed miR-125b and Bcl-2 expressions in pediatric patients with ALL and evaluated their clinical utility as molecular markers for the prediction of disease outcomes. RESULTS Downregulation of miR-125b and increased Bcl-2 expression levels in pediatric patients with ALL were associated with poor prognosis at diagnosis. At day 28 of induction, miR-125b was significantly increased, whereas Bcl-2 was downregulated. Loss of miR-125b during diagnosis and its elevation after therapy are strongly correlated with short leukemia-free survival and worse survival. Moreover, the combination of miR-125b with Bcl-2 markers can clearly enhance the prediction of the disease outcome. Finally, a univariate analysis highlighted the independent prognostic value of miR-125 in a pediatric patient with ALL. CONCLUSIONS miR-125b and Bcl-2 together are potent predictors for the prognosis and, therefore, can be used as therapeutic targets in childhood ALL.

Abstract
BACKGROUND PEGylated interferon (PEG-IFN) in combination with ribavirin is the gold standard for chronic hepatitis C virus (HCV). The majority of patients received PEG-IFN/ribavirin achieve a sustained viral response (SVR), but few cases failed to respond. It was evident that host genetic factors determine the treatment-induced viral clearance as well as spontaneous response. In the current study, the rs12979860 polymorphism of IL28β gene was analyzed and its association with the virological response to PEG-IFN treatment was determined. METHODS One hundred and fifty Egyptian patients with HCV genotype 4 treated with PEG-IFN/ribavirin were assessed at 12 and 24 weeks of therapy, the rs12979860 genotype was determined using TaqMan-based quantitative polymerase chain reaction. RESULTS Although the CC genotype was the most frequent (58%), the higher SVR was achieved for patients with favorable CC genotype (93%) in contrast to CT and TT genotypes. CONCLUSION we conclude that IL28B polymorphism is highly associated with SVR to therapy in the Egyptian population infected with HCV genotype 4 and patients who carry CC genotype have a higher chance of SVR.

Abstract
OBJECTIVES To investigate the correlation of homeobox (HOX) transcript antisense RNA expression with clinicopathological features and the clinical prognosis of the patients with chromosome 12p abnormalities associated acute myeloid leukemia (AML). We also investigate the association of 12p chromosomal on the expression of HOTAIR, miRNA-193a, and c-kit gene as targeting genes for HOTAIR in AML. METHODS AML patients with 12p chromosomal abnormalities were recruited and compared to AML with other chromosomal abnormalities rather than 12p. The long noncoding RNA (lncRNA) "HOTAIR," miR-193a, and c-Kit genes expression were measured in bone marrow samples using Syber green based real-time polymerase chain reaction. RESULTS We found a significant difference for the expression levels of HOTAIR, c-kit, and miR-193a between 12p abnormalities associated AML and those without. The survival analysis revealed that patient's with low expression levels of HOTAIR and c-kit had significantly better survival and leukemia free survival. In contrast, miR-193a was associated with better overall survival but not leukemia free survival. CONCLUSION 12p abnormalities associated AML were associated with worse prognosis. Our results proved that HOTAIR, miR-193a, and c-kit genes are independent prognostic predictors in 12p chromosomal associated AML; therefore it may represent a novel therapeutic application in AML in the future.

Abstract
Long non-coding RNA (LncRNA) is recently linked to various types of cancers, CCAT and PVT1 are two LncRNAs linked to t(8;21) associated Acute Myeloid Leukemia, the interplay between CCAT, PVT1 and the MYC proto-oncogene implicated in t(8;21) could present an opportunity for using LncRNA as prognostic biomarker or a target for therapy, We investigated the expression levels of LncRNAs in 70 patients; 30 with t(8;21) positive AML and 40 with t(8;21) negative AML, We found that CCAT1 and PVT1 are expressed in higher levels in t(8;21) positive -AML by 5.3 folds compared to t(8;21) negative group; the expression values were significantly associated with high-risk clinical criteria; moreover, they are associated with lower overall survival (OS) rate and leukemia-free survival (LFS), however we didn't find a statistically significant cut-off value of LncRNAs using the Cox regression analysis for Lnc_PVT1 except with LFS, we conclude that high expression levels of CCAT1 and PVT1 are associated with poor prognosis while being poor prognostic biomarkers in t(8;21) associated AML.

Abstract
AIM AND BACKGROUND Malignant pleural mesothelioma (MPM) is a lethal cancer mainly caused by chronic exposure of asbestos. In this pilot study, we aimed to assess the expression of serum RNA-based biomarker panel exploring their clinical utility as diagnostic and prognostic biomarkers for MPM. METHODS We have selected an MPM-specific RNA-based biomarker panel through bioinformatics analysis based on the integration of DNA damage regulated autophagy modulator 1 (DRAM1) and arylsulfatase A ( ARSA) gene expression with their epigenetic regulators microRNA ( miR-2053) and long noncoding RNA ( lncRNA-RP1-86D1.3). Then, quantitative real-time polymerase chain reaction (qPCR) validation in sera of 60 MPM patients, 20 chronic asbestos exposure patients, and 20 healthy volunteers was done. Lastly, the prognostic power of the selected panel was assessed. RESULTS The expression of serum DRAM1 messenger RNA (mRNA), ARSA mRNA, hsa-miR-2053 and lncRNA-RP1-86D1.3 were positive in 78.3%, 90%, 85%, and 83.3% of MPM patients, respectively. The RNA-based biomarker panel was able to discriminate between MPM patients and controls with high accuracy and their combined sensitivity reached 100% for the diagnosis of MPM. Kaplan-Meier analysis showed that hsa-miR-2053 is an independent prognostic factor of MPM. CONCLUSION Our preliminary data revealed that the chosen RNAs play an important role in driving MPM development and progression.

Abstract
Mortality rates of acute lymphoblastic leukemia (ALL) have improved over the past 20 years; however, a significant portion of deaths stems from the lack of prognostic biomarkers, which can direct therapy and overcome drug resistance. microRNA-155a (miRNA-155a) and miRNA-181a are two single-stranded miRNAs involved in the pathogenesis of many types of leukemia and lymphoma and is linked to drug resistance. We investigated their expression levels in 55 patients, 45 diagnosed with ALL and 10 as a control group. We found that miRNA-155a and miRNA-181a were significantly upregulated in the ALL group with both being linked to high levels of minimal residual disease and poor prognosis. miRNA-155a cutoff value was significant in discriminating between high- and low-risk ALL patients as well as between ALL patients and healthy controls, miRNA-181a cutoff value, however, was not significant. Both markers levels were significantly downregulated after therapy. We conclude that miR-155 is correlated with poor prognosis in ALL, whereas we couldn't link miRNA-181a to the prognosis in ALL. Moreover, the marked decrease in their expression after therapy could reflect their impact on disease outcome.

Abstract
AIM We aimed to examine the statistical association between serum expression of miRNA 661 (miR-661) and ATG-4B mRNA and hepatocellular carcinoma (HCC) based on in silico data analysis followed by clinical validation. PATIENTS & METHODS Quantitative reverse-transcriptase real-time PCR was used to examine the expression of miR-661 and ATG-4B mRNA in the sera of HCC patients versus control. RESULTS The expression of miR-661 and ATG-4B mRNA was positive in 97.14 and 77.14%, respectively, in HCC patients. The survival analysis showed that ATG-4B mRNA was an independent prognostic factor. CONCLUSION Our data are the first report of its kind regarding the considerable clinical significance of miR-661 and ATG-4B mRNA in HCC patients.

Abstract
AIM miRNAs may act as promising diagnostic and prognostic biomarkers of mesothelioma. This study integrates serum miR-548a-3p and miR-20a expression based on in silico data analysis followed by clinical validation in malignant mesothelioma patients (malignant pleural mesothelioma [MPM]). PATIENTS & METHODS Serum miR-548a-3p and miR-20a level was assessed in the serum of patients with MPM, chronic asbestos exposure and healthy volunteers by quantitative real-time PCR. RESULTS The expression of serum miR-548a-3p and miR-20a was positive in 91.6 and 96.7% MPM patients, respectively. Both miRNAs were able to segregate between cases and controls. The sensitivity of the combined chosen serum miRNAs reached 100% in the diagnosis of MPM. CONCLUSION The current work revealed that sera miR-548a-3p and miR-20a may serve as promising novel diagnostic tools for MPM.

Abstract
Aberrant microRNA (miRNA) expression participates in childhood acute lymphoblastic leukemia (ALL). This study aimed to investigate the expression of miRNA-100, miRNA-196a, and miRNA-146a among childhood ALL and study their correlation with other hematological parameters and different phenotypes. Peripheral blood mononuclear cells (PMNCs) were obtained from 85 childhood ALL and 25 healthy children for the detection of miRNA expression using quantitative real-time PCR. Significant higher median levels were reported for ALL compared to control children. The diagnostic efficacy for miRNA-146a was superior as both sensitivity and specificity were absolute. A significant correlation was observed between higher expression of miRNA-100 and lower platelet and lymphocyte counts; high expression of miRNA-146a showed significant correlation with low total leukocyte count (TLC) and lymphocyte counts. Significant relation was reported between studied miRNAs and different phenotyping. miRNA-100, miRNA-196a, and miRNA-146a have significant role in childhood ALL leukemogenesis, and they may be useful as biological diagnostic molecular markers.
