(9/17/2021) Hafez, Mohamed M; Abdel-Hafez, Lina Jamil M; Jamil, Lubna; Ibrahim, Sherine M
Background: Hepatitis C is considered one of the most popular diseases in Egypt. We aim is to clarify the association between Cluster of Differentiation 24 (CD24) polymorphism, Talin-1 gene expression, and the prevalence of hepatocellular carcinoma in Egyptian Hepatitis C virus patients. Methods: The link between CD24 polymorphism rs8734 and the prevalence of hepatocellular carcinoma was assessed between 200 control subjects and 400 hepatitis C virus patients (HCV), patients were classified as follows; 200 patients with HCV and 200 with HCV and hepatocellular carcinoma (HCC) by histopathological assessment and PCR-restriction fragment length polymorphism (PCR-RFLP). Results: The hepatitis c patients with HCC showed a significant increase in alpha - fetoprotein (AFP) and Talin-1 gene expression compared to patients with HCV as well as in healthy volunteers. Furthermore, the frequencies of CD 24 170 CT/TT genotype were significantly higher in HCV patients without complications (60%) when compared to CC genotype (40%) (OR= 6 at X2= 14.41, P = 0.0007), and in HCV with HCC patients (90%) when compared to CC genotype (10%) (OR= 36 at X2= 14.41, P = 0.0007). Conclusion: These data suggest that CD24 genetic polymorphism rs8734 and Talin-1 gene expression may be a significant determinant for the prevalence of hepatocellular carcinoma in HCV patients.

Association of Apelin Genetic Variants with Type Two Diabetes Mellitus in Egyptian Population.
(A SciTechnol Journal, 2019) Abdelhamid, Amr M; Hafez, Mohamed M; Ibrahim, Sherine M
Background and Aim: Apelin, the newly identified adipokine and the endogenous ligand for the APJ receptor is related to obesity and insulin resistance. The aim of the study was to investigate the association of 2 single-nucleotide polymorphisms (SNPs) in the apelin gene (APLN) with susceptibility to Type Two Diabetes Mellitus (T2DM) in the Egyptian population. Methods: Two SNPs on APLN were genotyped in 145 diabetic patients and 135 nondiabetic individuals, aged 40-60 years. Realtime polymerase chain reaction (RT-PCR) was used to analyze the 2 SNPs in both the diabetic and the healthy subjects. The association of the 2 SNPs (rs2281068 and rs3115759) in APLN and T2DM risk was investigated. Allele and genotype frequencies between patients and control groups were compared using the Chisquare (χ2 ) test. Results: In the apelin gene; GT/TT genotype of apelin risk genotypes of the rs2281068 variants was found to be significantly related with the risk of T2DM with the power (OR : 9.623, CI : 35.52 - 16.77) (P ≤ 0.001). while on the contrary, the GA/AA genotype of the rs3115759 variants was not at increased risk for T2DM (OR :1.25, CI : 0.785-2.09) (P=0.3408). Conclusions: Both association and functional studies suggested that SNP rs2281068 in APLN is associated with the risk of T2DM in the Egyptian population.

Background: Nanoparticles are recently playing a potential role in improving drug uptake and the treatment of diseases. A variety of nanoparticles, such as selenium nanoparticles (SeNPs) and Silver nanoparticles (AgNPs) have been used as drug carriers in various ways for treatment of cancers and liver diseases. Our aim in this study is to investigate the ability of AgNPs and SeNPs to target and treat the viral and bacterial infection of liver in rats and cell lines. Methods: For assessment of antioxidant activity of silver nanoparticles, six adult male albino rats were included in this study, liver slices were taken and assigned to 6 groups. Markers of hepatic functions, oxidative stress and inflammation in liver slices are carried out. While for assessment of antiviral activity of SeNPs, HBV-replicating human cell line HepG2 and normal human cell lines were used, hepatic and inflammatory alterations are determined through quantitative polymerase chain reaction (PCR) and comet assay techniques. Results: The effect of Ag-NPs on interleukin-6 (IL-6) and tumor necrosis factor (TNF-α) levels were reduced in different treated groups with Ag-NPs compared with the control and diseased groups. On the other hand, SeNPs revealed significant alterations in the inflammatory markers as well as DNA damage in the treated HBV- human cell line HepG2 compared to the diseased ones. Conclusion: Silver nanoparticles have the ability for producing various hepatic alterations and can inhibit the proliferation of hepatic stellate cells (HSCs) in a dose and size dependent manner. On the other hand, SeNPs showed excellent selectivity towards viral cells in the HepG2 cell lines. Both Ag-NPs and SeNPs might be a promising drug design for treating viral and bacterial liver diseases.

Nanoparticles are recently playing a potential role in improving drug uptake and the treatment of diseases. A variety of nanoparticles, such as selenium nanoparticles (SeNPs) and silver nanoparticles (AgNPs) have been used as drug carriers in various ways for treatment of cancers and liver diseases. Our aim in this study is to investigate the ability of AgNPs and SeNPs to target and treat the viral and bacterial infection of the liver in rats and cell lines. For assessment of antioxidant activity of AgNPs in rats with induced liver bacterial infection, six adult male albino rats were included in this study, liver slices were taken and assigned to 6 groups. Markers of hepatic functions, oxidative stress, and inflammation in liver slices are carried out. Although for assessment of antiviral activity of SeNPs, hepatitis B virus transfected (HBV)‐replicating human cell line HepG2 and normal hepatocyte cells were used, hepatic and inflammatory alterations are determined through quantitative polymerase chain reaction and comet assay techniques. The effect of AgNPs on interleukin‐6 and tumor necrosis factor levels were reduced in different treated groups with AgNPs compared with the control and diseased groups. On the other hand, SeNPs revealed significant alterations in the inflammatory markers as well as DNA damage in the treated HBV‐human cell line HepG2 compared to the diseased ones. AgNPs have the ability for producing various hepatic alterations and can inhibit the proliferation of hepatic stellate cells (HSCs) in a dose and size‐dependent manner. On the other hand, SeNPs showed excellent selectivity towards viral cells in the HepG2 cell lines.

Introduction: Lung cancer is the most common type of cancer, causing worldwide mortality. Therefore, this study is necessary for continuing research into new effective and safe treatments. Recently, herbal medicines have been used for the treatment of various diseases such as cancer. This study aimed to investigate the potential anti-proliferative activity and investigate the mechanisms of hesperidin extract on the non-small lung cancer cells A549 and H460 vs. cisplatin via targeting the miR 34a/PD-L1/NF-κB signalling pathway. Material and methods: To determine the cytotoxic effects of the hesperidin extract on non-small lung cancer cells, sulphorhdamine B assay was performed. To show the inhibition of migration by hesperidin extract, wound healing assay was conducted. A quantitative polymerase chain reaction test was used to quantify the expressions of miR-34a, programmed cell death ligand-1 (PDL-1), epidermal growth factor receptor (EGFR), and P53 genes, which are involved in apoptosis pathway. Also, cell cycle assay was performed by using a flow cytometer. Results: The hesperidin extract could significantly inhibit proliferation of non-small lung cancer cells A549 and H460. Western blot assay demonstrated that hesperidin induced suppression of nuclear factor κB signalling pathway. The messenger RNA expression levels of MiR-34a and P53 were up-regulated significantly by hesperidin treatment, while the EGFR and P53 genes were down-regulated. The flow cytometer confirmed that cell cycle arrest occurred at the sub-G1 and G2 phases in A549 and H460, respectively. Conclusions: Our study demonstrated that hesperidin extract could significantly inhibit non-small lung cancer cell growth by induction of the apoptosis signalling pathway. Therefore, hesperidin might open novel strategies for effective and safe cancer treatment and reduce the adverse side effects of several chemotherapeutic treatments such as cisplatin.
