Definition: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: This study aims to characterize the function of downregulated MicroRNA miR-205 in renal cell carcinoma (RCC), and show how the downstream zinc finger E-box-binding homeobox 2 (ZEB2) is negatively regulated by miR-205.', 'The expression of miR-205 was detected in RCC and adjacent non-tumor tissues using real-time polymerase chain reaction (PCR). The expression of miR-205 and ZEB2 was detected in RCC cell lines using real-time PCR. The luciferase reporter assay was used to assess ZEB2 as a target of miR-205. Protein levels of ZEB2, E-cadherin, and vimentin were measured by western blot after overexpression of miR-205 in ACHN cells. In vivo functions of miR-205 in ACHN cells were measured by MTT assays, migration and invasion assays, and flow cytometry.', 'MiR-205 was significantly downregulated in RCC samples and cell lines compared with matched non-tumor tissues and HK-2 cells, respectively. No significant difference was found in miR-205 expression between well differentiated and poorly to moderately differentiated groups or between phase I and phase II-III. ZEB2 was upregulated in RCC cell lines compared with expression in HK-2 cells. Upregulation of miR-205 expression caused the downregulation of ZEB2 and vimentin, and the upregulation of E-cadherin in ACHN cells. miR-205 also inhibited proliferation, migration, and invasion, and induced apoptosis of ACHN cells.
Output:
Is miRNA-205 a candidate tumor suppressor that targets ZEB2 in renal cell carcinoma?
