Exp Eye Res 2021; 210:108643. [PMID: 34058231 DOI: 10.1016/j.exer.2021.108643] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2021] [Revised: 04/24/2021] [Accepted: 05/24/2021] [Indexed: 12/27/2022]
Abstract
Choroidal melanoma is a devastating disease that causes visual loss and a high mortality rate due to metastasis. Luteolin, a potential anticancer compound, is widely found in natural plants. The aim of this study was to evaluate the antiproliferative, antiadhesive, antimigratory and anti-invasive effects of luteolin on choroidal melanoma cells in vitro and to explore its potential mechanism. Cell counting kit-8 (CCK-8) assays, 5-ethynyl-2'-deoxyuridine (EdU) assays, Cell adhesion, migration, and invasion assays were performed to examine the inhibitory effects of luteolin on cell cell viability, proliferation, adhesion, migration and invasion capacities, respectively. Considering the correlation between Matrix metalloenzymes and tumor metastasis, Enzyme-linked immunosorbent assays (ELISAs) were used to assess matrix metalloproteases MMP-2 and MMP-9 secretion. Western blotting was performed to detect p-PI3K P85, Akt, and p-Akt protein expression. The cytoskeletal proteins vimentin were observed with cell immunofluorescence staining. Luteolin can inhibit OCM-1 cell proliferation, migration, invasion and adhesion and C918 cell proliferation, migration, and invasion through the PI3K/Akt signaling pathway. Therefore, Luteolin may have potential as a therapeutic medication for Choroidal melanoma.

Wei C, Zhao X, Wang L, Zhang H. TRIP suppresses cell proliferation and invasion in choroidal melanoma via promoting the proteasomal degradation of Twist1. FEBS Lett 2020; 594:3170-3181. [PMID: 32640040 DOI: 10.1002/1873-3468.13882] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 06/24/2020] [Accepted: 07/02/2020] [Indexed: 12/18/2022]
Abstract
Choroidal melanoma (CM) remains the most prevalent form of intraocular malignancy, and the prognosis of affected patients is poor. While the E3 ubiquitin ligase TRAF-interacting protein (TRIP) is known to play key regulatory roles in multiple diseases, its relevance in CM remains uncertain. In the present study, we found that TRIP overexpression is sufficient to inhibit the proliferation, invasion, and epithelial-mesenchymal transition (EMT) of CM cells in vitro, whereas the opposite phenotypes are observed following TRIP knockdown. We further determined that TRIP is able to promote the K48-polyubiquitination of EMT-associated transcription factor Twist-related protein 1, thereby suppressing EMT progression. Together, our results suggest that TRIP plays an important role in regulating the progression of CM and that it may therefore be an important therapeutic target for the treatment of this disease.
