Nakashima S, Oda Y, Morita M, Ohta A, Morikawa T, Matsuda H, Nakamura S. Analysis of Active Compounds Using Target Protein Cofilin―Cucurbitacins in Cytotoxic Plant Bryonia cretica. Toxins (Basel) 2022; 14:toxins14030212. [PMID: 35324709 PMCID: PMC8955846 DOI: 10.3390/toxins14030212] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2022] [Revised: 03/14/2022] [Accepted: 03/14/2022] [Indexed: 02/04/2023] Open
Abstract
We examined a two-step target protein binding strategy that uses cofilin as the target protein to analyze the active constituents in Bryonia cretica. In the first step, we prepared the target protein, and used it to analyze the compounds binding to it in the second step. We used the methanolic extract of B. cretica as a library of possible active compounds. We conducted LC–MS analysis using information from our previous study. The peaks in the HPLC profile were identified as cucurbitacin D, isocucurbitacin D, and cucurbitacin I. As far as we know, there is no known study of the activity of isocucurbitacin D in this research field. Therefore, we examined the effects of isocucurbitacin D on cell proliferation and cofilin protein in human fibrosarcoma cell line HT1080 to confirm the effectiveness of this strategy. The cytotoxicity assay, the fibrous/globular actin ratio assay, and the immunoblotting analysis revealed that isocucurbitacin D showed a cytotoxic effect with disruption of target protein cofilin. The target protein binding strategy is a direct and straightforward method for finding new drug seeds from crude sources, such as natural plant extracts.

LncRNA CTC-497E21.4 promotes the progression of gastric cancer via modulating miR-22/NET1 axis through RhoA signaling pathway. Gastric Cancer 2020; 23:228-240. [PMID: 31451992 DOI: 10.1007/s10120-019-00998-w] [Citation(s) in RCA: 36] [Impact Index Per Article: 7.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2019] [Accepted: 08/16/2019] [Indexed: 02/07/2023]
Abstract
BACKGROUND Long non-coding RNAs (lncRNAs) have emerged as important roles in gastric cancer (GC). However, the role of the dysregulated lncRNAs in GC remained large unknown. We investigated the clinical significance, biological function and mechanism of CTC-497E21.4 in GC. METHODS Firstly, RTFQ-PCR was used to detect the expression of CTC-497E21.4 in GC. Furthermore, knockdown of CTC-497E21.4 was conducted to assess the effect of CTC-497E21.4 in vitro and vivo. Subcellular localization of CTC-497E21.4 was determined by nuclear plasmolysis PCR and FISH. We also predicted CTC-497E21.4 binding miRNAs and downstream target genes and evaluated its regulation of miR-22 by acting as a ceRNA. RESULT CTC-497E21.4 was upregulated in GC tissues and GC cell lines (P < 0.05), and the expression was associated with depth of invasion, lymph node metastasis, and neurological invasion. Besides, knockdown of CTC-497E21.4 inhibited cell proliferation, invasion and promoted cell cycle arrest in vitro and inhibited tumorigenesis in vivo. Mechanistic investigations indicated that CTC-497E21.4 acted as a ceRNA for miR-22 and regulated NET1 expression. CTC-497E21.4/miR-22-3p/NET1 participated in the RhoA signaling pathway in the GC progression. CONCLUSION CTC-497E21.4 competed with miR-22 to regulate the expression of NET1 and regulated the malignant progression of GC through RhoA signaling pathway.
