Abstract
Osteosarcoma is a highly aggressive cancer and lacks effective therapeutic targets. We found that L3MBTL2 acts as a tumor suppressor by transcriptionally repressing IFIT2 in osteosarcoma. L3MBTL2 recruits the components of Polycomb repressive complex 1.6 to form condensates via both Pho-binding pockets and polybasic regions within carboxyl-terminal intrinsically disordered regions; the L3MBTL2-induced condensates are required for its tumor suppression. Multi-monoubiquitination of L3MBTL2 by UBE2O results in its proteasomal degradation, and the UBE2O/L3MBTL2 axis was crucial for osteosarcoma growth. There is a reverse correlation between L3MBTL2 and UBE2O in osteosarcoma tissues, and higher UBE2O and lower L3MBTL2 are associated with poorer prognosis in osteosarcoma. Pharmacological blockage of UBE2O by arsenic trioxide can enhance L3MBTL2-induced condensates and consequently suppress osteosarcoma growth. Our findings unveil a crucial biological function of L3MBTL2-induced condensates in mediating tumor suppression, proposing the UBE2O-L3MBTL2 axis as a potential cancer therapeutic target in osteosarcoma.

The correlation between the expression of ubiquitin-conjugating enzyme 2C and prostate cancer prognosis. J Cancer Res Clin Oncol 2023:10.1007/s00432-023-04611-7. [PMID: 36752909 DOI: 10.1007/s00432-023-04611-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Accepted: 01/27/2023] [Indexed: 02/09/2023]
Abstract
PURPOSE Ubiquitin-conjugating enzyme E2 C (UBE2C) is known to show a causal relationship with cancer development and advancement. The role of UBE2C is to control the mitotic spindle checkpoint. Excess UBE2C has been identified in patients with advanced prostate cancer. The objective of the present study was to examine positive connections between the expression of UBE2C and prognostic factors for prostate cancer. METHODS Prostate cancer patients' clinical data were analysed. Tissue microarrays (TMAs) were also performed for human prostate cancer tissues (n = 335) and adjacent non-neoplastic tissues (n = 22). TMA slides were incubated with antibodies against UBE2C. Cores were scored by a pathologist who was blind to cancer results. RESULTS Of 335 prostate cancer patients, 200 could be assessed for biochemical recurrence, clinical recurrence, and overall survival. Human prostate cancer tissues showed higher expression of UBE2C than adjacent non-neoplastic tissues. High expression level of UBE2C showed a strong positive relationship with a high prostate-specific antigen (PSA), Gleason's score, and pathological stage of prostate cancer. Patients with a higher UBE2C grade demonstrated greater lymphatic engagement of prostate cancer than those with a lower UBE2C grade. CONCLUSION The expression of UBE2C has positive correlations with several prognostic factors for prostate cancer. Thus, investigating the expression level of UBE2C staining is a promising tool for predicting prostate cancer prognosis.

Feng C, Gong L, Wang J. Arborinine from <em>Glycosmis parva</em> leaf extract inhibits clear-cell renal cell carcinoma by inhibiting KDM1A/UBE2O signaling. Food Nutr Res 2022; 66:8714. [PMID: 36185617 PMCID: PMC9487452 DOI: 10.29219/fnr.v66.8714] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2022] [Revised: 06/14/2022] [Accepted: 07/11/2022] [Indexed: 11/25/2022] Open
Abstract
Background Arborinine is a natural product isolated from Globigerina parva (G. parva) leaf extract that shows strong anticancer activity with its role in clear-cell renal cell carcinoma (ccRCC) unreported. Objective We aim to evaluate the role of Arborinine in ccRCC. Design Arborinine was tested for its effects in ccRCC cell lines in vitro and in silico. Results Arborinine conferred inhibitory effect to ccRCC cells at reasonable doses. Arborinine showed inhibitory effects on Lysine Demethylase 1A (KDM1A) in ccRCC cells and decreased levels of KDM1A outputs and on epithelial mesenchymal transition (EMT) markers. Arborinine significantly inhibited proliferation, apoptosis, and cell cycle progression and migration of ccRCC cells. Using in silico ChIP analysis and luciferase activity validation, we identified Ubiquitin-conjugating enzyme E2O (UBE2O) as an active transcription target downstream of KDM1A. UBE2O expression was not only correlated with KDM1A expression but also associated with worsened prognosis in ccRCC. Overexpression of UBE2O abrogated cancer-inhibitory effect of Arborinine. Discussion Arborinine holds promise as an additive in the treatment of ccRCC. Conclusions We have shown for the first time that Arborinine showed inhibitory effect on ccRCC via KDM1A/UBE2O signaling.
