[PMID: 36284084 PMCID: PMC9596416 DOI: 10.1038/s41389-022-00440-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/05/2022] [Revised: 10/06/2022] [Accepted: 10/11/2022] [Indexed: 02/07/2023] Open
Abstract
While an important role for the SUMO protease SENP1 is recognized in multiple solid cancers, its role in renal cell carcinoma (RCC) pathogenesis, particularly the most dominant subtype, clear cell RCC (ccRCC), is poorly understood. Here we show that a combination of high HIF2α and SENP1 expression in ccRCC samples predicts poor patient survival. Using ccRCC cell models that express high HIF2α but low SENP1, we show that overexpression of SENP1 reduces sumoylation and ubiquitination of HIF2α, increases HIF2α transcriptional activity, and enhances expression of genes associated with cancer cell invasion, stemness and epithelial-mesenchymal transition. Accordingly, ccRCC cells with high HIF2α and SENP1 showed increased invasion and sphere formation in vitro, and local invasion and metastasis in vivo. Finally, SENP1 overexpression caused high HIF2α ccRCC cells to acquire resistance to a clinical mTOR inhibitor, everolimus. These results reveal a combination of high SENP1 and HIF2α expression gives particularly poor prognosis for ccRCC patients and suggest that SENP1 may be an attractive new target for treating metastatic RCC (mRCC).

Abstract
Human adipose-derived stem cells (hADSCs) are adult mesenchymal cells that have attracted the interest of clinical scientists and surgeons due to their large number of advantages including ease of access and expansion, abundance in cell culture, high proliferative rates, and lower senescence. SUMO/sentrin specific protease 1 (SENP1) is a critical protease that is required during the process of SUMOylation and deSUMOylation, which are dynamic mechanisms that influence cell cycle progression, cell proliferation, and apoptotic status. However, the contribution of SENP1 to these important cellular processes in hADSCs is largely uncharacterized and further studies in this area are required. Here, we show for the first time that after knock out SENP1 in hADSCs, their capacity to migrate and proliferate were inhibited, while apoptosis was enhanced. However, SENP1 did not significantly influence the morphology and MSC-related phenotypes of the hADSCs. These results highlight a role for SENP1 during hADSC growth, and its potential as a therapeutic target to improve the efficacy and safety of hADSCs in the clinic.

Abstract
RNA polymerase II-associated factor 1 (PAF1)/pancreatic differentiation 2 (PD2) is a core subunit of the human PAF1 complex (PAF1C) that regulates the RNA polymerase II function during transcriptional elongation. PAF1/PD2 has also been linked to the oncogenesis of pancreatic ductal adenocarcinoma (PDAC). Here, we report that PAF1/PD2 undergoes posttranslational modification (PTM) through SUMOylation, enhancing the radiation resistance of PDAC cells. We identified that PAF1/PD2 is preferentially modified by small ubiquitin-related modifier 1 (SUMO 1), and mutating the residues (K)-150 and 154 by site-directed mutagenesis reduces the SUMOylation. Interestingly, PAF1/PD2 was found to directly interact with the promyelocytic leukemia (PML) protein in response to radiation, and inhibition of PAF1/PD2 SUMOylation at K-150/154 affects its interaction with PML. Our results demonstrate that SUMOylation of PAF1/PD2 increased in the radiated pancreatic cancer cells. Furthermore, inhibition of SUMOylation or PML reduces the cell growth and proliferation of PDAC cells after radiation treatment. These results suggest that SUMOylation of PAF1/PD2 interacts with PTM for PDAC cell survival. Furthermore, abolishing the SUMOylation in PDAC cells enhances the effectiveness of radiotherapy. Overall, our results demonstrate a novel PTM and PAF1/PD2 interaction through SUMOylation, and inhibiting the SUMOylation of PAF1/PD2 enhance the therapeutic efficacy for PDAC.

Abstract
BACKGROUND Renal cell carcinoma or RCC is a type of malignancy commonly occurred in the human kidney especially in the adults. The pathogenesis of RCC involves the complex networking of multiple signaling pathways, and the underlying molecular mechanisms remain largely unclear. OBJECTIVES This study aimed to elucidate the regulatory functions of UBA2 and explore its potential downstream molecules during the tumor progression in RCC. METHODS In this paper, the expression of UBA2 and associated molecules was examined by RT-qPCR and western blotting. The proliferative activity of RCC cells was determined using CCK-8 assay and immunofluorescence staining of proliferation-related marker Ki-67. Moreover, the cell distribution and apoptosis were evaluated by flow cytometry. RESULTS Our results revealed the upregulation of UBA2 in RCC tissues and cells, and the high-expression of UBA2 was also associated with bigger tumor size, more advanced stage, and poorer overall survival in RCC patients. In addition, UBA2 knockdown was able to suppress the growth of RCC cells and induced cell cycle arrest at G0/G1 phase. Furthermore, the p53 signaling could be the novel target of UBA2 in RCC, and UBA2 affected the biological behaviors of RCC cells in a p53-dependent manner. CONCLUSION In summary, UBA2 was able to enhance the proliferation, inhibit the apoptosis, and suppress cell cycle arrest in RCC cells by targeting the p53 pathway.

Abstract
Sumoylation is the Post-translational modification gaining most of the research interest recently. Sumoylation is involved in various crucial functions of the cell such as regulation of cell cycle, DNA damage repair, apoptosis, etc. Oncology is advancing in radiotherapy, targeted chemotherapy, various forms of immunotherapy and targeted gene therapy. Researches are being conducted to prove its connotation with a variety of cancers and inhibitors are being developed to obstruct the fatal effect caused by misbalance of the SUMO-catalytic cycle. It has been shown that up-regulation of certain enzymes of Sumoylation correlates with cancer incidence in most of the cases. However, in some cases, down-regulation also associates with cancer invasion such as underexpression of UBC9 in initial stage breast cancer. This can aid in future study, treatment, and diagnosis of a variety of cancers including breast cancer, prostate cancer, lung adenocarcinoma, melanoma, multiple myeloma, etc. Various mechanistic assays are being developed and used to identify potential inhibitors against the dysregulated proteins of Sumoylation. This review summarizes the normal roles of the enzymes involved in the SUMOcatalytic cycle, their misbalanced regulation leading to tumorigenesis and nearly all the potent inhibitors identified to date, while after detailed studied it was observed that ML-792 could be a promising inhibitor in treating cancers by inhibiting Sumoylation enzymes.

Abstract
Background Dysregulated microRNAs are involved in the macrophage polarization and atherosclerotic development. Apart from microRNAs, alteration in DNA methylation is considered as one of the most frequent epigenetic changes. The purpose of the research is to investigate the altered methylation status of miR-181b in the circulating monocytes from patients with coronary artery disease (CAD) and explore the underlying mechanisms. Methods We examined the methylation status of miR-181b in purified circulating monocytes from patients with CAD and healthy controls. We then transfected monocytes with miR-181b mimics and determined the role of miR-181b on the phenotypic switch of macrophages and inflammatory response. DNA methylation levels determined by MethyLight PCR and pyrosequencing at the promoter of miR-181b significantly increased in CAD patients. Based on TargetScan database, we identified PIAS1 as the target gene of miR-181b and explored the interaction of miR-181b and PIAS1 by Dual-Luciferase assay, quantitative PCR and immunoblots. We also investigated the role of miR-181b and PIAS1 on macrophage polarization and inflammation. Results Hypermethylation at the promoter of miR-181b directly contributed to the decrease of miR-181b activity and expression. Overexpression of miR-181b reduced M1 polarization and facilitated M2 polarization determined by quantitative PCR. While knockdown of PIAS1 induced KLF4 degradation and SUMOylation in monocytes, miR-181b mimics reverse the KLF4 SUMOylation via suppression of PIAS1. Moreover, KLF4 SUMOylation by PIAS1 reversed M1 polarization induced by depletion of miR-181b in monocytes. Conclusions Hypermethylation of miR-181b induces M1 polarization and promotes atherosclerosis through activation of PIAS1 and KLF4 SUMOylation in macrophages.

Mol Oncol 2020; 14:2288-2312.

Abstract
LIN28A is a conserved RNA-binding protein that inhibits the biogenesis of let-7 microRNAs, thus promoting cancer progression. However, mechanisms underlying the activation of the LIN28A-let-7 signaling pathway remain poorly understood. Here, we show that LIN28A is SUMOylated in vivo and in vitro at K15, which is increased by hypoxia but reduced by chemotherapy drugs such as Cisplatin and Paclitaxel. SUMOylation of LIN28A aggravates its inhibition of let-7 maturation, resulting in a stark reduction in let-7, which promotes cancer cell proliferation, migration, invasion, and tumor growth in vivo. Mechanistically, SUMOylation of LIN28A increases its binding affinity with the precursor let-7 (pre-let-7), which subsequently enhances LIN28A-mediated recruitment of terminal uridylyltransferase TUT4 and simultaneously blocks DICER processing of pre-let-7, thereby reducing mature let-7 production. These effects are abolished in SUMOylation-deficient mutant LIN28A-K15R. In summary, these findings shed light on a novel mechanism by which SUMOylation could regulate the LIN28A-let-7 pathway in response to cellular stress in cancer cells.

Abstract
PURPOSE It is well established now that protein sumoylation acts as an important regulatory mechanism mediating control of ocular development through regulation of multiple transcription factors. Yet the functional mechanisms of each factor modulated remain to be further explored using the available in vitro systems. In this regard, various ocular cell lines including HLE, FHL124, αTN4-1, N/N1003A and ARPE-19 have been demonstrated to be useful for biochemical and molecular analyses of normal physiology and pathogenesis. We have recently examined that these cell lines express a full set of sumoylation enzymes E1, E2 and E3. Following this study, here we have examined the localization of these enzymes and determined their differential localization patterns in these major ocular cell lines. METHODS The 5 major ocular cell lines were cultured in Dulbecco's modified Eagle's medium (DMEM) containing fetal bovine serum (FBS) or rabbit serum (RBS) and 1% Penicillin- Streptomycin. The localization of the 3 major sumoylation enzymes in the 5 major ocular cell lines were determined with immunohistochemistry. The images were captured with a Zeiss LSM 880 confocal microscope. RESULTS we have obtained the following results: 1) The sumoylation enzymes SAE1, UBC9 and PIAS1 are distributed in both nucleus and cytoplasm, with a much higher level concentrated in the nucleus and the neighboring cellular organelle zone in all cell lines; 2) The sumoylation enzyme UBA2 was highly concentrated in both cytoplasm membrane, cytoskeleton and nucleus of all cell lines; 3) The ligase E3, RanBP2 was exclusively localized in the nucleus with homogeneous distribution. CONCLUSIONS Our results for the first time established the differential localization patterns of the three types of sumoylation enzymes in 5 major ocular cell lines. Our establishment of the differential localization patterns of the three types of sumoylation enzymes in these cell lines help to predict their functional importance of sumoylation in the vision system. Together, our results demonstrate that these cell lines can be used for assay systems to explore the functional mechanisms of sumoylation mediating ocular development and pathogenesis.

[PMID: 30636610 DOI: 10.2174/1566524019666190112143636] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2018] [Revised: 12/26/2018] [Accepted: 01/07/2019] [Indexed: 01/26/2023]
Abstract
PURPOSE Protein sumoylation is a well established regulatory mechanism to control many cellular processes such as chromatin structure dynamics, transcriptional regulation of gene expression, cell proliferation and differentiation, cell transformation and carcinogenesis, autophagy and senescence. In the vertebrate vision system, we and others have revealed that sumoylation plays important roles in regulating differentiation of several ocular tissues during eye development. To further elucidate the functional mechanisms of sumoylation, in vitro assay systems are needed. Currently, the five major cell lines including αTN4-1, FHL124, HLE, N/N1003A and ARPE-19 have been extensively used to test the biochemical and molecular aspects of normal vision physiology and various disease processes. Thus, we conducted the study on the expression patterns of the three types of sumoylation enzymes, the activating enzymes SAE1 and UBA2, the conjugating enzyme UBC9, and the ligating enzymes such as RanBP2 and PIAS1 in these ocular cell lines. METHODS The 5 major ocular cell lines were cultured in Dulbecco's modified Eagle's medium (DMEM) containing fetal bovine serum (FBS) or rabbit serum (RBS) and 1% Penicillin- Streptomycin. The mRNA levels were analysed with qRT-PCR. The protein levels were determined with western blot analysis and quantitated with Image J. RESULTS we have obtained the following results: 1) For the mRNAs encoding E1 SAE1 and UBA2, E2 UBC9 and E3 PIAS1, the highest level of expression was observed in αTN4-1 cells; For the mRNA encoding RanBP2, the highest level of expression was detected in N/N1003A cells; 2) In contrast to the mRNA expression patterns, a similar level of the SAE1 protein was observed in the all five cell lines, and so is true with UBA2 protein in all cells except for N/N1003A where over fourfold of enrichment in UBA2 protein was observed compared with other cell lines; 3) A similar level of UBC9 protein was also detected in all cells except for N/N1003A where more than one-fold of decrease in UBC9 level was found compared with other cell lines; 4) For E3 ligases, we did not identify the regular PIAS1 band in N/N1003A cells, the remaining cells have a level of PIAS1 with difference of less than 0.6-fold; all cells except for FHL124 cells have a similar level of RanBP2, and a 70% drop in RanBP2 was observed in FHL124 cell. CONCLUSIONS Our determination of the differential expression patterns of the three types of sumoylation enzymes in the 5 ocular cell lines help to understand sumoylation functions in vertebrate eye.

Abstract
Aim: Protein inhibitor of activated STAT ( PIAS) family includes transcriptional regulator proteins with SUMO E3 ligase activity. They regulate expression of several genes involved in cell proliferation, differentiation and survival. Method: We evaluated expression of PIAS1–4 genes in 54 breast cancer tissues and their paired adjacent noncancerous tissues. Results: PIAS2 and PIAS3 genes were significantly downregulated in tumoral tissues compared with adjacent noncancerous tissues. PIAS1–3 expressions were significantly lower in estrogen receptor (ER+) samples compared with ER- samples while PIAS4 had the opposite trend. PIAS3 expression was significantly higher in grade 1 samples compared with grade 2 samples. Conclusion: These findings highlight the role of PIAS genes in the pathogenesis of breast cancer and their association with determinants of response to antihormone therapies.

Abstract
PURPOSE Protein sumoylation is a well established regulatory mechanism that regulates chromatin structure and dynamics, cell proliferation and differentiation, stress response and cell apoptosis. In the vertebrate eye, we and others have shown that sumoylation plays an indispensable role in regulating eye development. During stress induction and aging process, the ocular tissues gradually loss their normality and develop major ocular diseases such as cataract and aging-related macular degeneration. We have recently demonstrated that sumoylation actively regulates differentiation of lens cells, whether this process is implicated in lens pathogenesis remains to be investigated. In this study, we have demonstrated that transparent mouse lenses treated with glucose oxidase and UVA irradiation undergo in vitro cataract formation, and associated with this process, the expression patterns of the 3 sumoylation enzymes have been found significantly altered. METHODS Four-week-old C57BL/6J mice were used in our experiment. Lenses were carefully excised from eyes and cultured in M199 medium (Sigma 3769) for at least 12 hours. Transparent lenses (without surgical damage) were selected for experimentation. The lenses were exposed to UVA for 60 min or treated with 30 mU/mL glucose oxidase (GO, MP Biomedicals, 1673) to induce cataract formation. The mRNA levels were analysed with qRT-PCR. The protein levels were determined with western blot analysis and quantitated with Image J. RESULTS we have obtained the following results: 1) Both GO treatment and UVA irradiation can induce cataract formation in the in vitro cultured mouse lenses; 2) With GO treatment, the mRNAs and proteins for the 5 sumoylation enzymes were all significantly downregulated; 3) With UVA irradiation, the changes in the expression patterns of the mRNAs and proteins for the SAE1, UBA2 , UBC9 and PIAS1 were opposite, while the mRNAs were upregulated either significantly (for SAE1, UBA2 and UBC9) or slightly (PIAS1), the proteins for all 4 sumoylation enzymes were downregulated; For RanBP2, the UVA induced changes in both mRNA and protein are consist with the GO treatment. CONCLUSION Under GO and UVA irradiation conditions, the expression levels of both mRNA and protein for the three major sumoylation enzymes were significantly changed. Our results suggest that altered expression patterns of the sumoylation enzymes are associated with oxidative stressinduced cataractogenesis.

Int J Oncol 2018; 53:2010-2020.

Abstract
Osteosarcoma stem cells are able to escape treatment with conventional chemotherapeutic drugs, as the majority of them are in a quiescent state. Recent reports have suggested that small ubiquitin-like modifiers (SUMOs) serve important roles in the maintenance of cancer stem cell stemness. Therefore, a potential strategy to increase the effectiveness of chemotherapeutic agents is to interfere with SUMO modification of proteins associated with the maintenance of stemness in osteosarcoma stem cells. The present study revealed a significant decrease in the expression of SUMO1 specific peptidase 1 (SENP1) in osteosarcoma tissues and osteosarcoma cell lines, and SENP1 expression was much lower in osteosarcoma stem cells than in non-cancer stem cells. Further experiments indicated that the low levels of SENP1 were essential for maintenance of stemness in osteosarcoma stem cells. Overexpression of SENP1 resulted in a marked decrease in the maintenance of stemness, but only slightly induced apoptosis of osteosarcoma cells, which is crucial to reduce the side effects of drugs on normal precursor cells. Finally, SENP1 overexpression led to a significant increase in the sensitivity of osteosarcoma stem cells to the herpes simplex virus 1 thymidine kinase gene in combination with ganciclovir in vitro and in vivo. In conclusion, the present study described a novel method to increase the sensitivity of osteosarcoma stem cells to chemotherapeutic drugs. Notably, this approach may significantly reduce the required dose of conventional chemotherapeutic drugs and reduce side effects.

SUMO2/3 modification of activating transcription factor 5 (ATF5) controls its dynamic translocation at the centrosome. J Biol Chem 2018; 293:2939-2948. [PMID: 29326161 DOI: 10.1074/jbc.ra117.001151] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/28/2017] [Revised: 12/21/2017] [Indexed: 11/06/2022] Open
Abstract
Activating transcription factor 5 (ATF5) is a member of the ATF/cAMP response element-binding protein family of transcription factors. ATF5 regulates stress responses and cell survival, proliferation, and differentiation and also plays a role in viral infections, cancer, diabetes, schizophrenia, and the olfactory system. Moreover, it was found to also have a critical cell cycle-dependent structural function at the centrosome. However, the mechanism that controls the localization of ATF5 at the centrosome is unclear. Here we report that ATF5 is small ubiquitin-like modifier (SUMO) 2/3-modified at a conserved SUMO-targeting consensus site in various types of mammalian cells. We found that SUMOylation of ATF5 is elevated in the G1 phase of the cell cycle and diminished in the G2/M phase. ATF5 SUMOylation disrupted the interaction of ATF5 with several centrosomal proteins and dislodged ATF5 from the centrosome at the end of the M phase. Of note, blockade of ATF5 SUMOylation deregulated the centrosome cycle, impeded ATF5 translocation from the centrosome, and caused genomic instability and G2/M arrest in HeLa cells. Our results indicate that ATF5 SUMOylation is an essential mechanism that regulates ATF5 localization and function at the centrosome.
