[PMID: 38266402 DOI: 10.1016/j.ygyno.2023.12.031] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2023] [Revised: 11/08/2023] [Accepted: 12/29/2023] [Indexed: 01/26/2024]
Abstract
OBJECTIVE This study explored promising prognostic and immune therapeutic candidate biomarkers for OC and determined the expression, prognostic value, and immune effects of UCHL3. METHODS UCHL3 expression and clinical data were investigated using bioinformatic analysis. CCK8 and transwell assays were conducted to evaluate the impact of UCHL3 on proliferation and migration, and the effects of UCHL3 were further validated in a mouse model. Univariate and least absolute shrinkage and selection operator regression analyses were performed to construct a novel UCHL3-related prognostic risk model. Gene set enrichment analysis (GSEA) and immune analysis were performed to identify the significantly involved functions of UCHL3. Finally, bioinformatic analysis and immunohistochemistry were performed to explore the effect of UCHL3 on chemotherapy. RESULTS UCHL3 expression was upregulated and associated with worse overall survival (OS) in OC. UCHL3 depletion repressed cell proliferation and migration both in vitro and in vivo. Furthermore, 237 genes were differentially expressed between the high and low UCHL3 expression groups. Subsequently, a UCHL3-related prognostic signature was built based on six prognostic genes (PI3, TFAP2B, MUC7, PSMA2, PIK3C2G, and NME1). Independent prognostic analysis suggested that age, tumor mutational burden, and RiskScore can be used as independent prognostic factors. The immune infiltration analysis and GSEA suggested that UCHL3 expression was related to the immune response. In addition, UCHL3 expression was higher in platinum-resistant OC patients than in platinum-sensitive patients. UCHL3 overexpression was associated with poorer OS. CONCLUSION UCHL3 overexpression contributes to aggressive progression, poor survival, and chemoresistance in OC. Therefore, UCHL3 may be a candidate prognostic biomarker and potential target for controlling progression and platinum resistance in OC.

Abstract
Hepatocellular carcinoma (HCC) is the most common type of primary hepatic liver cancer. Dysregulated Wnt/β-catenin activation is closely related to the progression of cancer. Nevertheless, the mechanism that sustains the abnormal expression of β-catenin in HCC has yet to be identified. In this study, we find that UCHL3 is overexpressed in HCC tissues and correlated with β-catenin protein level. High expression of UCHL3 is associated with poor prognosis. UCHL3 knockdown markedly reduces the protein level of β-catenin in HCC cells. TOP-luciferase activity and β-catenin target genes expression are also decreased upon UCHL3 depletion. We find that the ARM domain of β-catenin is required for the interaction with UCHL3. UCHL3 increases β-catenin protein stability via removing K48-specific poly-ubiquitin chains from β-catenin protein. Furthermore, the depletion of UCHL3 induces ferroptosis and hinders the growth, invasion, and stem cell properties of HCC cells. These impacts could be restored by the overexpression of β-catenin. In addition, the UCHL3 inhibitor TCID inhibits the aggressive phenotype of HCC through the degradation of β-catenin. In general, our results indicates that UCHL3 increases the stability of β-catenin, which in turn facilitates tumorigenesis of HCC, suggesting that targeting UCHL3 may be a promising approach for the treatment of HCC.

Abstract
BackgroundHepatocellular carcinoma (HCC) is a common malignant tumor associated with a poor prognosis. Ubiquitin carboxyl-terminal hydrolase L3 (UCHL3) has been reported to promote diverse tumors, but little is known about its role in HCC.MethodsExpression levels of UCHL3 in Huh7 and Hep3B cells were measured by qRT-PCR. UCHL3, Vimentin protein levels, and ubiquitination levels were determined by Western blot assay. co-immunoprecipitation, Immunofluorescence, and IHC were used to detect the interaction and expression association between UCHL3 and Vimentin in the cells. Wound healing and Transwell assays were used to measure cell migration. Spheroid formation assay were used to assess stem-like properties.ResultsUCHL3 expression was found to be significantly elevated in HCC and associated with poor prognosis. UCHL3 promoted migration and stem-like properties of HCC cells. Vimentin was identified as a potential de-ubiquitination substrate of UCHL3 and UCHL3 interacted with and promoted the de-ubiquitination of Vimentin, enhancing its stability. Moreover, the suppression of UCHL3 by siRNA or the inhibition by TCID upregulated ubiquitinated Vimentin. Vimentin attenuated the suppression of cell migration caused by knockdown of UCHL3.ConclusionUCHL3 was highly expressed in HCC and functioned as an oncogene. Vimentin is a novel substrate of UCHL3 and its stabilization and de-ubiquitination enhanced HCC cell migration.

UCHL3 promotes cervical cancer development and metastasis by stabilizing NRF2 via deubiquitination. Biochem Biophys Res Commun 2023; 641:132-138. [PMID: 36527747 DOI: 10.1016/j.bbrc.2022.11.065] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Accepted: 11/22/2022] [Indexed: 11/24/2022]
Abstract
Cervical cancer is one of the most lethal gynaecological malignancies in females. The deubiquitylase UCHL3 has been studied as an oncogenic factor in multiple cancers. However, the expression pattern and function profile of UCHL3 in cervical cancer hasn't been fully characterized. Here, we revealed that UCHL3 was highly expressed in cervical cancer and overexpressed UCHL3 predicted a poor survival probability in cervical cancer patients. Our findings showed that knockdown of UCHL3 inhibited cell growth, migration and invasion in cervical cancer cells while UCHL3 knockdown inhibited cervical cancer development and metastasis in vivo in mouse models. Mechanistically, co-immunoprecipitation assay showed that UCHL3 directly interacted with NRF2. Knockdown of UCHL3 decreased NRF2 expression while overexpression of UCHL3 stabilized NRF2 via deubiquitination. In addition, overexpression of UCHL3 with C92A mutation didn't affect NRF2 stability. Moreover, we revealed that overexpression of NRF2 could antagonize the function of UCHL3 knockdown in cervical cancer cells. Collectively, our findings suggest that UCHL3 promotes cervical cancer development and metastasis by stabilizing NRF2 via deubiquitination. Thus, UCHL3/NRF2 axis could be utilized to develop efficient treatments for cervical cancer patients.

Abstract
Melanoma is one of the most aggressive skin cancers and a major cause of cancer-linked deaths worldwide. As the morbidity and mortality of melanoma are increasing, it is necessary to elucidate the potential mechanism influencing melanoma progression. Tumor tissues and adjacent normal tissues (5 cm away from tumors) from 22 melanoma patients at the I-II stage and 39 patients at the III-VI stage were acquired. The expression of LINC01063 in melanoma was estimated by quantitative PCR. Functional assays were employed to investigate the function of LINC01063 in melanoma. Mechanism assays were adopted to explore the mechanism of LINC01063. LINC01063 knockdown impeded melanoma cell proliferation, migration, invasion, and epithelial-mesenchymal transition as well as melanoma tumor growth. Mechanistically, LINC01063 acted as an miR-5194 sponge to upregulate SOX12 expression. Finally, LINC01063 was tested to facilitate the malignant behaviors of melanoma cells via targeting miR-5194/SOX12. LINC01063 was significantly upregulated in melanoma. Specifically, LINC01063 displayed a higher level in patients at an advanced stage or with metastasis than those at an early stage or without metastasis. Our study revealed the oncogenic effects of LINC01063 on melanoma cell/tumor growth and its molecular mechanism involving miR-5194/SOX12, which might support LINC01063 to be the potential prognostic or therapeutic biomarker against melanoma.
