Abstract

Background: Prostatic anomalies are common in tumor or infection condition. The enlargement of prostate gland affects the epithelial cell polarity that involves epithelial-mesenchymal transition (EMT). Transition into mesenchymal is mediated by transcription factor ZEB1 and E-cadherin protein. Upregulation of ZEB1 and loss of E-Cadherin expression were associated to proliferation and metastasis of malignancy cells. This study aims to describe the correlation of ZEB1 and E-cadherin expression in prostatic anomaly.Materials and method: Samples were Formalin Fixed Paraffin Embedded (FFPE) block consist of 8 block Benign Prostatic Hyperplasia (BPH), 6 blocks High Grade Prostatic Intraepithelial Neoplasia (HGPIN) and 6 blocks Prostate Carcinoma (PCA). The blocks then sliced into 5 sections to be prepared for RNA extraction procedures. ZEB1 and E-Cadherin expression was analyzed by semi-quantitative procedures using PCR and electrophoresis. Correlation between ZEB1 and E-Cadherin espression was analyzed using Spearman’s rank correlation.Results: Relative expression of ZEB1 and E-cadherin mRNA in each group of prostatic anomaly were not significantly different (p>0.05). ZEB1 and E-Cadherin mRNA expression showed a significant and moderate level of negative correlation (p<0.05; 0.40 < r < 0.59). Increasing of ZEB1 mRNA expression will be followed by decreasing of E-Cadherin mRNA expression.Conclusion: ZEB1 negatively correlates with E-cadherin due to EMT process in prostatic anomaly. High expression of ZEB1 induced down-regulation of E-cadherin and vise versa. Various studies can be developed, especially the development of targeted therapy against ZEB1 to suppress the EMT process by increasing the expression of E-cadherin.Keywords: epithelial-mesenchymal transition (EMT), ZEB1, E-Cadherin, BPH, HGPIN, PCA

Abstract

The current pandemic of Coronavirus disease 2019, or known as COVID-19, has been claimed as Public Health Emergency of International Concern by WHO on 30 January 2020. According to WHO, there 47.362.304 confirmed cases and 1.211.986 deaths reported due to COVID-19 and still counting. This article investigates the involvement of gastrointestinal symptoms in COVID-19 related to the pathogenesis, transmission, and severity of the disease. The data was collected by keyword searching through EBSCO, PubMed, Google scholar, and additional references from retrieved articles. This article analyzes studies investigating gastrointestinal symptoms in Covid-19. The studies found gastrointestinal symptoms in COVID-19 confirmed patients such as abdominal pain, diarrhea, nausea, vomiting, constipation, and melena. Two studies showed that COVID-19 patients with gastrointestinal symptoms tended to have more severe disease. ACE2, as the receptor of S protein, was found abundantly in intestinal enterocytes besides in the respiratory system. Enterocyte abnormality induces decreased absorption of NA+, water, and mucosal disaccharides. It leads to increased undigested mono and disaccharides, carbohydrates, fats, and protein into the colon. As a result, the colon is unable to absorb sufficient water, leading to diarrhea. Gastrointestinal symptoms are commonly found in patients with COVID‐19, and the trend is increasing in the later stage of the epidemic. SARS‐CoV‐2 enters gastrointestinal epithelial cells and the feces of COVID‐19 patients are potentially infectious. The virus also found in wastewater system and may cause water pollution. Hence, further studies investigating gastrointestinal symptoms and possibility of fecal oral transmission should be conducted.
