Mostafa, T., L. A. Rashed, D. A. Sabry, I. Osman, N. Nabil, F. Kareem, and I. A. Mostafa, "Serum L-carnitine and vitamin D levels may be low among oral sildenafil citrate non-responders.", International journal of impotence research, vol. 31, issue 2, pp. 85-91, 2019 Mar. Abstract

This cross-sectional comparative study aimed to compare serum L-carnitine and 25(OH)D levels between men with ED non-responding for oral sildenafil citrate and healthy volunteers. Overall, 192 men, recruited from two University Hospitals, were allocated into two equal groups of matched age; healthy potent men and men with ED non-responders for oral sildenafil citrate. Oral sildenafil citrate non-responders self-reported inadequate erectile responses after four attempts using 100 mg with the manufacturer's guidelines relative to meals, associated medications, and sexual stimulation/arousal. Exclusion criteria were: diabetes, cardiovascular disorders, beta blockers treatment, morbid obesity, thyroid disorders, post-radical prostatectomy, and hepatic/renal failure. All participants were subjected to; history taking, clinical examination, validated IIEF-5 questionnaire, estimation of serum L-carnitine by calorimetric method and serum 25(OH)D by ELISA method. Compared with potent controls, ED men non-responders for oral sildenafil citrate showed significant decreases in the mean serum L-carnitine level (16.8 ± 3.6 uM/L versus 66.3 ± 11.9 uM/L, P = 0.001), the mean serum 25(OH)D level (21.2 ± 7.1 ng/ml versus 54.6 ± 7.9 ng/mL, P = 0.001) and IIEF-5 score (7.8 ± 2.6 versus 23.9 ± 1.3). Serum L-carnitine showed significant positive correlation with IIEF-5 scores (r = 0.873, P = 001), serum 25(OH)D (r = 0.796, P = 0.001) and significant negative correlation with the age (r = -0.515, P = 0.001). Serum 25(OH)D showed significant positive correlation with IIEF-5 scores (r = 0.855, P = 0.001) and significant negative correlation with the age (r = -0.223, P = 0.005). It is concluded that normal homeostasis of serum L-carnitine and 25(OH)D play a role in male sexual health being significantly decreased in ED non-responding for oral sildenafil citrate.

Gendy, "Aryl hydrocarbon receptor (AhR) rs2066853 gene polymorphism association with infertile oligoasthenoteratozoospermic men and seminal oxidative stress.", Environmental science and pollution research international, 2017 Feb 04. Abstract

This study aimed to assess the association between aryl hydrocarbon receptor (AhR) rs2066853 gene polymorphism with infertile oligoasthenoteratozoospermic (OAT) men and seminal oxidative stress (OS). A total of 170 Egyptian men were allocated according to their semen analysis into fertile normozoospermic controls (n = 50) and infertile OAT men (n = 120). They were subjected to history taking, clinical examination, semen analysis, estimation of seminal glutathione peroxidase (GPx), and malondialdehyde (MDA). AhR rs2066853 gene polymorphism was identified in the blood by PCR-RFLP. Comparing infertile OAT men with fertile controls, AhR rs2066853 genotypes showed decreased prevalence for wild homozygous genotype GG (35.8 vs 56%) and for heterozygous genotype GA (17.5 vs 30%) and an increased prevalence for homozygous genotype AA (46.7 vs 14%). Distribution of alleles of AhR rs2066853 among OAT men compared with fertile men showed decreased prevalence of G allele (44.6 vs 71%) and an increased prevalence of A allele (55.4 vs 29%). Seminal MDA demonstrated significant increase whereas seminal GPx demonstrated significant decrease in cases with AA and GA/AA genotypes compared to cases with GG genotype. It is concluded that there is a significant association between AhR rs2066853 genotype polymorphism with decreased sperm parameters as well as increased seminal oxidative stress in infertile OAT men.

Motawi, T. M. K., S. A. EL-Maraghy, D. Sabry, and N. A. Mehana, "The expression of long non coding RNA genes is associated with expression with polymorphisms of HULC rs7763881 and MALAT1 rs619586 in hepatocellular carcinoma and HBV Egyptian patients.", Journal of cellular biochemistry, vol. 120, issue 9, pp. 14645-14656, 2019. Abstract

Long noncoding RNAs (lncRNAs), highly upregulated liver cancer (HULC), metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), lncRNA-AF085935, and lncRNA-uc003wbd have been implicated in hepatocellular carcinoma (HCC). Single-nucleotide polymorphism (SNP) in HULC and MALAT1 are associated with HCC susceptibility. However, association between these SNPs and lncRNA-AF085935 and lncRNA-uc003wbd expression and their potential clinical value in differentiating HCC from both hepatitis B virus (HBV)-infected Egyptian patients and the healthy specimens have not been explored yet. In the present study, SNPs rs7763881 in HULC and rs619586 in MALAT1 were genotyped in 70 HBV-positive HCC, 70 HBV patients, and 70 healthy controls in Egyptian population and the level of serum lncRNA-AF085935 and lncRNA-uc003wbd of all the subjects was assayed by quantitative real-time polymerase chain reaction. HULC rs7763881 AC/CC genotype was significantly associated with decreased HCC risk. Similarly, AG/GG of MALAT1 rs619586 was associated with decreased HCC risk with a borderline significance. Serum lncRNA-AF085935 and lncRNA-uc003wbd levels were upregulated in HBV-positive HCC and HBV patients vs controls and discriminated these groups by receiver operating characteristic analysis. Patients carrying AC/CC genotype of rs7763881 and AG/GG of rs619586 had lower serum lncRNA-AF085935 and lncRNA-uc003wbd levels compared with AA genotype. In conclusion, genetic variants of lncRNA HULC and lncRNA MALAT1 are associated with the decreased susceptibility to HCC in HBV-persistent carriers and are correlated with serum lncRNA-AF085935 and lncRNAuc003wbd levels, two potential noninvasive diagnostic biomarkers for HCC.

Motawi, T. M. K., N. A. H. Sadik, D. Sabry, N. N. Shahin, and S. A. Fahim, "rs2267531, a promoter SNP within glypican-3 gene in the X chromosome, is associated with hepatocellular carcinoma in Egyptians.", Scientific reports, vol. 9, issue 1, pp. 6868, 2019. Abstract

Hepatocellular carcinoma (HCC) is a major health concern in Egypt owing to the high prevalence of hepatitis C virus (HCV) infection. HCC incidence is characterized by obvious male predominance, yet the molecular mechanisms behind this gender bias are still unidentified. Functional variations in X-linked genes have more impact on males than females. Glypican-3 (GPC3) gene, located in the Xq26 region, has lately emerged as being potentially implicated in hepatocellular carcinogenesis. The current study was designed to examine the association of -784 G/C single nucleotide polymorphism (SNP) in GPC3 promoter region (rs2267531) with HCC susceptibility in male and female Egyptian HCV patients. Our results revealed a significant association between GPC3 and HCC risk in both males and females, evidenced by higher C allele and CC/C genotype frequencies in HCC patients when compared to controls. However, no such association was found when comparing HCV patients to controls. Moreover, GPC3 gene and protein expression levels were significantly higher in CC/C than in GG/G genotype carriers in males and females. The CC/C genotype exhibited a significant shorter overall survival than GG/G genotype in HCC patients. In conclusion, GPC3 rs2267531 on the X chromosome is significantly associated with HCC, but not with HCV infection, in the Egyptian population.

Motawi, T. M. K., D. Sabry, N. W. Maurice, and S. M. Rizk, "Role of mesenchymal stem cells exosomes derived microRNAs; miR-136, miR-494 and miR-495 in pre-eclampsia diagnosis and evaluation.", Archives of biochemistry and biophysics, vol. 659, pp. 13-21, 2018 Dec 01. Abstract

BACKGROUND: Pre-eclampsia (PE) is one of the most threatening pregnancy complications. So far neither a secure, competent therapy for PE nor effective biomarkers for a premature discovery has been achieved. However, currently, the use of released microRNAs (miRNAs) as potential biomarkers and therapy targets for various diseases is the dominating area of research. The aim of our study was to identify miRNAs 136, 494 and 495 genes expression in exosomes of peripheral blood compared to umbilical cord mesenchymal stem cells (UCMSCs) conditioned media released exososomes in patients with PE, as valuable markers for PE early prediction.

METHODS: Blood samples were collected from 100 patients with PE and 100 control with normal pregnancies. Thirty fresh umbilical cord samples of women with healthy pregnancies (n = 15) and PE patients (n = 15) were retrieved during caesarean deliveries and UCMSCs were isolated from Wharton jelly. The expression of miRNAs 136, 494 and 495 in exosomes of peripheral blood and UCMSCs conditioned media was measured using quantitative real-time PCR method. Unpaired t-test, Pearson correlation test and Receiver operator characteristic (ROC) analysis were used for data analysis.

RESULTS: Our study revealed a significantly higher expression levels of miRNAs 136, 494 and 495 in exosomes of peripheral blood and matched with UCMSCs released exosomes from patients with PE compared to normal pregnancies (p = 0.000). In peripheral blood of PE, they were 6.4, 3.9 and 2.1 folds higher, respectively. ROC analysis revealed that the sensitivity and specificity values of miRNA-136 were 95% and 100%, respectively, with a cut-off value of 2.55. The sensitivity and specificity values of miRNA-494 were 86% and 95%, respectively, with a cut-off value of 0.47. The sensitivity and specificity values of miRNA-495 were 90% and 83%, respectively, with a cut-off value of 1.287.

CONCLUSION: Our findings suggest that exosomes derived miRNA-136, miRNA-494 and miRNA-495 could be promising circulating biomarkers in early detection of PE. Furthermore, UCMSCs released exosomes miRNA-136, miRNA-494 and miRNA-495 genes expression confirmed peripheral blood results analysis.

This study was conducted to evaluate the effect of mesenchymal stem cells (MSCs) and a novel curcumin derivative (NCD) on HepG2 cells (hepatoma cell line) and to investigate their effect on Notch1 signaling pathway target genes. HepG2 cells were divided into HepG2 control group, HepG2 cells treated with MSC conditioned medium (MSCs CM), HepG2 cells treated with a NCD, HepG2 cells treated with MSCs CM and NCD, and HepG2 cells treated with MSCs CM (CM of MSCs pretreated with a NCD). Expression of Notch1, Hes1, VEGF, and cyclin D1 was assessed by real-time, reverse transcription-polymerase chain reaction (RT-PCR) in HepG2 cells. In addition, HepG2 proliferation assay was performed in all groups. Notch1 and its target genes (Hes1 and cyclin D1) were downregulated in all treated groups with more suppressive effect in the groups treated with both MSCs and NCD. Also, treated HepG2 cells showed significant decrease in cell proliferation rate. These data suggest that modulation of Notch1 signaling pathway by MSCs and/or NCD can be considered as a therapeutic target in HCC.

BACKGROUND: Bio-products from stem/progenitor cells, such as extracellular vesicles, are likely a new promising approach for reprogramming resident cells in both acute and chronic kidney disease. Forty CKD patients stage III and IV (eGFR 15-60 mg/ml) have been divided into two groups; twenty patients as treatment group "A" and twenty patients as a matching placebo group "B". Two doses of MSC-derived extracellular vesicles had been administered to patients of group "A". Blood urea, serum creatinine, urinary albumin creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) have been used to assess kidney functions and TNF-α, TGF-β1 and IL-10 have been used to assess the amelioration of the inflammatory immune activity.

RESULTS: Participants in group A exhibited significant improvement of eGFR, serum creatinine level, blood urea and UACR. Patients of the treatment group "A" also exhibited significant increase in plasma levels of TGF-β1, and IL-10 and significant decrease in plasma levels of TNF-α. Participants of the control group B did not show significant improvement in any of the previously mentioned parameters at any time point of the study period.

CONCLUSION: Administration of cell-free cord-blood mesenchymal stem cells derived extracellular vesicles (CF-CB-MSCs-EVs) is safe and can ameliorate the inflammatory immune reaction and improve the overall kidney function in grade III-IV CKD patients.

BACKGROUND: The current study aimed at testing the effect of corticosteroid therapy on serum levels of interleukin-10 (IL-10) and IL-17 as well as lncRNA-AF085935 in patients of rheumatoid arthritis (RA) associated with hepatitis C virus (HCV) and evaluating the usefulness of using these parameters to predict the therapeutic efficacy of steroids in these patients.

METHODS: Thirty healthy control subjects and 65 chronic HCV patients with RA were included in our study. Patients were subjected to clinical examination, abdominal ultrasound, and liver biopsy and received 6-methyl-prednisolone (PDN) 16 mg/day for 48 weeks. Blood samples were collected from all subjects and serum was separated to assess IL-10 and IL-17 by ELISA and HCV RNA and lncRNA-AF085935 by qRT-PCR.

RESULTS: Our study revealed that there were significant increases in serum levels of IL-10, IL-17 and lncRNA-AF085935 in RA patients associated with HCV compared with healthy control subjects. Also there were significant increases in serum levels of IL-10 and HCV RNA and a significant decrease in serum level of IL-17 in patients after corticosteroid therapy, while lncRNA-AF085935 is not significantly changed.

CONCLUSION: LncRNA-AF085935 might be a useful candidate biomarker for the early detection of RA associated with HCV, providing potential new strategies for early screening and therapy of these patients. IL-17 is a non-invasive prognostic marker to predict the efficacy of corticosteroid therapy in RA patients associated with chronic hepatitis C.

Interleukin 17 (IL-17) is one of the pro-inflammatory cytokine. Psoriasin is a noticeably over-expressed protein found in the skin lesions of psoriatic patients. Our current study was planned to examine the association of (- 947 A/G) single nucleotide polymorphism (SNP) in IL-17RA promoter region (rs4819554) with psoriasis susceptibility in Egyptian psoriatic patients. Our study included 100 patients and 100, age as well as sex matched, control groups. IL-17RA SNP association was studied using allelic discrimination. RT-qPCR and ELISA were done to assess IL-17 expression. ELISA was performed to assess psoriasin expression. Our study showed a significant association between IL-17 rs4819554 SNP and psoriasis risk, evidenced by higher G allele and AG genotype frequencies in psoriatic patients when compared to controls (allelic: OR 2.283, 95% CI 1.321-3.946, p = 0.003, and genotype: OR 3.026, 95% CI 1.356-6.752, p = 0.007). Additionally, serum psoriasin level was significantly increased when comparing psoriatic patients to controls (p = 0.0003). Moreover, significant increase in IL 17 gene and protein level in AA, AG psoriatic genotypes compared to the corresponding genotypes in normal control (p = 0.0004). IL-17 rs4819554 is significantly associated with psoriasis, and with psoriasin level, in the Egyptian population.

Abstract

Colorectal cancer (CRC) is a major cause of death worldwide. Novel non-invasive, high diagnostic value screening test is urgently needed to improve survival rate, treatment and prognosis. Stable, small, circulating microRNA (miRNA) offers unique opportunities for the early diagnosis of several diseases. It acts as tumor oncogenes or suppressors and involve in cell death, survival, and metastasis. Communication between miRNA and carcinogenesis is critical but it still not clear and needs further investigation. The aim of our study is to evaluate the role of miR-210, miR-21, miR-126, as non-invasive diagnostic biomarkers for screening, early detection of CRC, studying their correlation with prognostic variables, and clarifying the roles of miRNAs on HIF-1α-VEGF signaling pathway. The expression of miR-210, miR-21 and miR-126 was performed using qRT-PCR in adenocarcinoma (no = 35), adenomas (no = 51), and neoplasm free controls (no = 101). Serum levels of VEGF and HIF-1α was determined by ELISA Kit. The results show that the expression of miR-210, miR-21, VEGF, HIF-1α was significantly up-regulated while that miRNA-126 was down-regulated in both adenocarcinoma and adenomas compared with controls (p < 0.001 for each). No significant difference was noted comparing patients with adenocarcinoma and adenomas. The three miRNAs correlated with VEGF, HIF-α. The miR-210 and miR-21 associated with TNM classification and clinical staging of adenocarcinoma (p < 0.001) and they show high diagnostic value with sensitivity and specificity 88.6%, 90.1% and 91.4%, 95.0% respectively. Our study revealed that circulating miR-210, miR-21 were up-regulated while miR-126 was down-regulated in CRC and adenomas patients, they all correlated with TNM staging and they had high diagnostic value. HIF-1α VEGF signaling pathways regulated by miRNAs played a role in colon cancer initiation. To the best of our knowledge, this is the first study of this miRNAs panel in CRC in our community. These data suggested that these biomarkers could be a potential novel, non-invasive marker for early diagnosis, screening and predicting prognosis of CRC. Understanding the molecular functions by which miRNAs affect cancer and understanding its roles in modulating the signaling output of VEGF might be fruitful in reducing the incidence and slowing the progression of this dark malignancy.

Background and Objectives: The release of microvesicles (MVs) from mesenchymal stem cells (MSCs) has been implicated in intercellular communication, and may contribute to beneficial paracrine effects of stem cell-based therapies. We investigated the effect of administration of MSC-MVs on the therapeutic potential of carbon tetrachloride (CCL) induced liver fibrosis in rats.

Methods: Our work included: isolation and further identification of bone marrow MSC-MVs by transmission electron microscopy (TEM). Liver fibrosis was induced in rats by CCl4 followed by injection of prepared MSC-MVs in injured rats. The effects of MSC-MVs were evaluated by biochemical analysis of liver functions, RNA gene expression quantitation for collagen-1, transforming growth factor (TGF-), interleukin-1 (IL-1), vascular endothelial growth factor (VEGF) by real time reverse transcription PCR (RT-PCR) techniques. Finally histopathological examination of the liver tissues was assessed for all studied groups.

Results: BM-MSC-MVs treated group showed significant increase in serum albumin levels, VEGF quantitative gene expression (p<0.05), while it showed a significant decrease in serum alanine transaminase (ALT) enzyme levels, quantitative gene expression of TGF-, collagen-1, IL-1 compared to CCL fibrotic group (p<0.05). Additionally, the histopathological assessment of the liver tissues of BM-MSC-MVs treated group showed marked decrease in the collagen deposition & improvement of histopathological picture in comparison with CCL fibrotic group.

Conclusions: Our study demonstrates that BM-MSC-MVs possess anti-fibrotic, anti-inflammatory, and pro-angiogenic properties which can promote the resolution of CCL induced liver fibrosis in rats.

AIM: The aim of the current study was to evaluate the therapeutic and regenerative effects of MSCs derived exosomes in the treatment of type 1 DM and to compare its effects with MSCs themselves. The experiment was done on forty albino rats grouped as follows, group (1): Ten healthy rats, group (2): Ten induced type 1 DM rats, group (3): Ten induced type 1 DM rats received exosomes intraperitoneally, and group (4): Ten induced type 1 DM rats received MSCs intraperitoneally. Serum glucose and plasma insulin levels were assessed weekly. QRT-PCR was done to assess regeneration of pancreatic beta cells by measuring insulin, Pdx1, Smad2, Smad3 and TGFβ genes. Additionally, histopathological and immune-histochemical examinations were done to confirm pancreatic tissue regeneration.

RESULTS: Regarding the assessed genes (insulin, Pdx1, Smad2, Smad3 and Tgfβ) gene expression in MSCs treated group showed significant increase compared to diabetic group (p value < 0.001) and gene expression in exosomes treated group was increased significantly compared to diabetic and MSCs treated groups (p value < 0.001). Histopathological and immune-histochemical examination revealed regeneration of pancreatic islets in both treated groups.

CONCLUSION: MSCs Derived exosomes showed superior therapeutic and regenerative results than MSCs themselves.

Khalil, "Interplay Between Helicobacter pylori Infection, Interleukin-11, and Leukemia Inhibitory Factor in Gastric Cancer Among Egyptian Patients.", Journal of interferon & cytokine research : the official journal of the International Society for Interferon and Cytokine Research, vol. 38, issue 11, pp. 517-525, 2018 Nov. Abstract

Helicobacter pylori is a ubiquitous Gram-negative bacterium, that is responsible for gastric mucosal inflammation. It is the most common risk factor for gastric cancer (GC). The current study aimed to investigate the association between interleukin-11 (IL-11) and leukemia inhibitory factor (LIF) levels among H. pylori-infected Egyptian patients with gastritis and GC. One hundred forty-seven patients with gastric lesions were endoscopically biopsied and assessed using rapid urease test and immunohistochemistry. Quantitative real-time polymerase chain reaction was done for the detection of H. pylori load in gastric biopsies and detection of LIF as well as IL-11 relative gene expression. The mean values of H. pylori load, LIF, and IL-11 were significantly elevated in GC patients compared to gastritis group (P < 0.0001). A positive significant correlation was detected between mucosal levels of LIF, IL-11, and H. pylori load in both groups. Both LIF and IL-11 had the same pattern of expression in gastric tissues with different types of gastritis and different types and grades of gastric carcinoma. This report could clarify the molecular events associated with the immune response against H. pylori infection and H. pylori-associated pathology. Therefore, development of immunotherapy strategies against H. pylori-induced cytokines becomes inevitable.
