The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 2.4 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 2.8 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.5 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00049 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.59 SJR: 0.429 SNIP: 0.507 CiteScore™:: 3.9 H-Index: 49

Краткое описание

The notorious lung metastatic capability of osteosarcoma aggravates patient mortality and remains the primary challenge to be overcome. We investigated the effect of (−)-epigallocatechin-3-gallate (EGCG) on the metastasis capability of osteosarcoma cells. We performed cytotoxicity assays (MTT) to determine the appropriate concentration of EGCG for experiments. Migration, invasion, wound-healing, and adhesion assays were performed to assess the effect of EGCG on the metastasis of osteosarcoma. Changes in the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) signaling pathway were investigated using Western blot analyses. In addition, a MEK inhibitor (U0126) was used in invasion assays to determine the effect of the MEK/ERK signaling pathway. We found that EGCG may markedly inhibit the migration and invasion capacity of osteosarcoma cells, which occurred concurrently with inhibition of the expression of phospho-MEK and phospho-ERK. Inhibitors of MEK inhibited the invasion of osteosarcoma cells, and this effect could be enhanced by EGCG. We also detected the expression of c-Jun N-terminal kinase, p38, and their respective phospho-proteins, but did not find any meaningful changes. Taken together, our results demonstrated that EGCG could inhibit the metastasis capability of osteosarcoma cells by inhibiting MEK/ERK signaling activity and may provide new therapeutic value for osteosarcoma.
