Identifying the association between polymorphisms in the GZMB and IFIH1 genes and psoriasis in Egyptians.

OBJECTIVES: This study aims to examine whether the genetic variants in the genes for Granzyme B (GZMB) and Interferon Induced with Helicase C domain 1 (IFIH1) were associated with psoriasis. BACKGROUND: Psoriasis, a papulosquamous skin disease, was initially thought of as a disorder primarily of epidermal keratinocytes but is now recognized as one of the most common immune-mediated disorders. It is caused by the interplay between multiple genetic and environmental risk factors. SUBJECTS AND METHODS: This case-control study has 65 participants with psoriasis and 65 healthy controls. Real-time PCR was used to genotype GZMB (rs8192917) and IFIH1 (rs35667974). RESULTS: Genotype occurrence and allelic spreading for both SNPs are in Hardy - Weinberg equilibrium. The genotype and allele distributions of rs35667974 showed no differences between the studied groups. Regarding rs8192917, compared to Group II, there is a statistically significant rise in the CC genotype and C allele in Group I. Higher PASI scores are detected in the C/C and C/T genotypes more than the T/T genotype. Univariate and multivariate analyses revealed that BMI, catalase, MDA, and rs8192917 (C/C) are associated with psoriasis. CONCLUSION: GZMB rs8192917 was significantly related to psoriasis risk; its C allele is likewise associated with psoriasis vulnerability. However, our investigation found no link between rs35667974 and psoriasis.

Identification of potential biomarkers for SLE through mRNA expression profiling.

BACKGROUND: Systemic lupus erythematosus (SLE) is an autoimmune disease that influences numerous body systems. Furin, tristetraprolin (TTP), and NOD, LRR, and pyrin domain-containing protein 3 (NLRP3) contribute in developing autoimmune illnesses. AIM: Understandthe role of furin, TTP, and NLRP3 mRNA gene expression in SLE pathogenesis and prognosis. Methods: Total 210 individuals were enrolled, divided in two group: cases and control; 105 participants in each group.  Real-time quantitative PCR for furin, TTP,and NLRP3 mRNA gene expression were determined for each subject. RESULTS: SLE patients showed significantly higher serum furin [median 20.10 (0.0-162.88) in comparison with control group [median 1.10 (0.33-8.64)] with significant pvalue (p < 0.001), for NLRP3 expression [median 7.03 (0.0-282.97) compared to control group [median 1.0 (0.44-9.48)] with significant p value (p = 0.006)but lower TTP [median 2.37 (0.0-30.13)] in comparison with control group [median 7.90 (1.0-29.29)] with significant p value (p < 0.001) . Elevated levels of Furin and NLRP3 and low levels of TTP were linked to increased illness activity. CONCLUSION: Furin and NLRP increase in SLE and higher with illness activity. TTP is lowerin SLE and negatively correlates with disease activity.

Utility of a microRNA panel in diagnosis and prognosis of hepatitis C-associated hepatocellular carcinoma.

BACKGROUND: Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer and the leading cause of cancer mortality. Various studies have linked dysregulated microRNA expression to liver cancers, but those related to viral hepatitis-related HCC are limited. METHODS: We investigated the diagnostic and prognostic roles of circulating miR-331-3p, miR-23b-3p, and miR-3194-5p in EDTA-treated blood samples of 50 hepatitis C virus (HCV) HCC patients, 50 HCV cirrhotic patients, and 50 healthy controls using quantitative real-time polymerase chain reaction. RESULTS: We found that miR-23b-3p and miR-3194-5p were significantly downregulated, whereas miR-331-3p was upregulated in HCC patients compared with controls. Also, these miRNAs were significantly dysregulated in HCC compared with cirrhotic patients. For the diagnosis of HCC, miR-331-3p and the combined miRNAs panel had the highest area under the curve (AUC), followed by miR-3194-5p. The highest AUC for differentiating metastatic from nonmetastatic patients was shown by miR-331-3p and the combined miRNAs panel, followed by miR-23b-3p. Dysregulation of miRNAs was associated with poor clinicopathological manifestations. Finally, miR-331-3P was found to be an independent risk factor for metastatic lesions in HCC. CONCLUSION: Overall, the assessed miR-331-3p, miR-23b-3p, and miR-3194-5p were significantly associated with poor clinicopathological features of HCC and could be used to discriminate HCV-related HCC patients from cirrhosis and differentiating metastatic from nonmetastatic patients, primarily miR-331-3p along with combined miRNAs. Moreover, miR-331-3p was found to be an independent factor for metastatic lesions.
