Abstract
UHRF proteins catalyze the ubiquitination of target proteins and are involved in regulating gene expression. Some studies reported a reduced expression of UHRF2 in acute leukemia cells, but the role of UHRF2 in hematopoiesis remains unknown. Here, we generated Uhrf2-/- mice to clarify the role of UHRF2 deletion in hematopoiesis. Compared to Uhrf2+/+ mice, Uhrf2-/- mice showed no differences in complete blood counts, as well as bone marrow (BM) findings and spleen weights. Proportions of cells in progenitor fractions in BM were comparable between Uhrf2+/+ mice and Uhrf2-/- mice. However, in competitive repopulation assays with BM transplants (BMT), the proportions of Uhrf2-/- cells were decreased relative to Uhrf2+/+ cells in all lineages. After the second BMT, Uhrf2-/- neutrophils were few, while 20-30% of Uhrf2-/- T cells and B cells were still detected. RNA sequencing showed downregulation of some genes associated with stem-cell function in Uhrf2-/- hematopoietic stem/progenitor cells (HSPCs). Interestingly, trimethylated histone H3 lysine 9 was increased in Uhrf2-/- HSPCs in a cleavage under targets and tagmentation assay. While UHRF2 deletion did not cause hematologic malignancy or confer a growth advantage of HSPCs, our results suggest that UHRF2 may play a role in the regulation of hematopoiesis.

Abstract
Autophagy have critical implications in the proliferation and metastasis of HCC. In the current study, we aimed to explore the underlying mechanisms of UHRF2 regulates HCC cell autophagy and HCC progression. We initially determined the relationship between UHRF2 and HCC autophagy, oncogenicity and patient survival through GSEA database and TCGA database. We mainly investigated the effect of UHRF2 on HCC development and autophagy through western blot, electron microscopy, and immunofluorescence. Functionally, UHRF2 was positively involved in the autophagy activation. Overexpression of UHRF2 reduced apoptosis in HCC cells, and promote the malignancy phenotype of HCC both in vitro and in vivo. Mechanistically, PRDX1 bound to UHRF2 and upregulated its protein expression to facilitate the biological function of UHRF2 in HCC. Meanwhile, UHRF2 bound to autophagy-related protein PARP1 and upregulated PARP1 protein level. The results showed that UHRF2 promoted autophagy and contributed to the malignant phenotype of hepatocellular carcinoma by regulating PARP1 levels. In summary, a novel interaction between PRDX1, UHRF2, and PARP1 was revealed, suggesting that UHRF2 could inspire a potential biomarker and potential therapeutic target for HCC.

Abstract
Background Researches showed RNA methylation genes can affect the prognosis of tumors. Thus, the study aimed to comprehensively analyze the effects of RNA methylation regulatory genes in prognosis and treatment of colorectal cancer (CRC). Methods Prognostic signature associated with CRCs were constructed by differential expression analysis, Cox and Least Absolute Shrinkage and Selection Operator (LASSO) analyses. Receiver operating characteristic (ROC) and Kaplan-Meier survival analyses were used to validate the reliability of the developed model. Gene Ontology (GO), Gene set variation analysis (GSVA), and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed for functional annotation. Finally, normal and cancerous tissue were collected to validate gene by quantitative real-time PCR (qRT-PCR). Results A prognostic risk model based on leucine rich pentatricopeptide repeat containing (LRPPRC) and ubiquitin-like with PHD and ring finger domains 2 (UHRF2) was constructed and relevant to the overall survival (OS) of CRC. Functional enrichment analysis revealed that collagen fibrous tissue, ion channel complex and other pathways were significantly enriched, which might help explain the underlying molecular mechanisms. There were significant differences in ImmuneScore, StromalScore, ESTIMATEScore between high- and low-risk groups (p < 0.05). Ultimately, qRT-PCR validation showed that a significant upregulation in the expression of LRPPRC and UHRF2 in cancerous tissue, which verified the effectiveness of our signature. Conclusion In conclusion, 2 prognostic genes (LRPPRC and UHRF2) related to RNA methylation were identified by bioinformatics analysis, which might supply a new insight into the treatment and evaluation of CRC.

Abstract
The aim of this study was to investigate the functions and molecular mechanism of miR-196a in esophageal cancer (EC). miR-196a as well as UHRF2 and TET2 mRNA and protein levels in EC tissues and cells were detected using quantitative real-time PCR or western blot, respectively. Cell proliferation was evaluated via MTT assay. Transwell assays were used to detect cell migration. In addition, the targeted relationship between miR-196a and UHRF2 was assessed through a dual luciferase reporter assay. Enzyme-linked immunosorbent assay was performed to detect the levels of the cytosine intermediates 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC). We found increased miR-196a expression in EC tissues and cells but decreased UHRF2 and TET2 expression. Next, functional experiments showed that knockdown of miR-196a or UHRF2 overexpression suppress EC cell proliferation and migration. miR-196a negatively regulates TET2 expression by directly targeting UHRF2. UHRF2 overexpression decreased 5mC levels but increased 5hmC levels. Furthermore, TET2 downregulation reversed the functions of miR-196a inhibition on EC cell proliferation and migration. Collectively, our study suggested that miR-196a was closely related to the progression of EC possibly by regulating the UHRF2/TET2 axis. Thus, miR-196a represents a potential new EC therapeutic target.

Abstract
The UHRF protein family consists of multidomain regulatory proteins that sense modification status of DNA and/or proteins and catalyze the ubiquitylation of target proteins. Through their functional domains, they interact with other molecules and serve as a hub for regulatory networks of several important biological processes, including maintenance of DNA methylation and DNA damage repair. The UHRF family is conserved in vertebrates and plants but is missing from fungi and many nonvertebrate animals. Mammals commonly have UHRF1 and UHRF2, but, despite their high structural similarity, the two paralogues appear to have distinct functions. Furthermore, UHRF1 and UHRF2 show different expression patterns and different outcomes in gene knockout experiments. In this review, we summarize the current knowledge on the molecular function of the UHRF family in various biological pathways and discuss their roles in epigenetics, development, gametogenesis, and carcinogenesis, with a focus on the mammalian UHRF proteins.

Abstract
Emerging evidence revealed that UHRF2 was implicated in a variety of human diseases, especially in cancer. However, the biological function, clinical significance and underly mechanisms of UHRF2 in hepatocellular carcinoma (HCC) is largely unknown. We analyzed the expression of UHRF2 in 371 HCC tissues and 50 para-cancerous tissues of TCGA database. We found that UHRF2 was significantly upregulated in HCC tissues, which was further confirmed in HCC cells and tissues by western blot. More importantly, the level of UHRF2 was correlated with pathological grade and clinical stage, and the patients with high level of UHRF2 had lower overall survival, disease-free survival and higher recurrence rate than those with low UHRF2 level. Univariate and multivariate Cox regression analysis revealed that high level of UHRF2 might be an independent prognostic factor for HCC patients. Functional investigations suggested that ectopic expression of UHRF2 could promote the proliferation, migration and invasion of HCC cell lines, whereas knock down of UHRF2 exhibited an opposite effect. Additionally, gene set enrichment analysis indicated that ERBB signaling pathway was upregulated in patients with high level of UHRF2. Pearson correlation analysis indicated that the expression of UHRF2 was positively correlated with ErbB3 and its downstream targets SOS1, Ras and Raf-1. Furthermore, we found that overexpression of UHRF2 could upregulate the expression of ErbB3, SOS1, Ras and Raf-1. Our findings suggested that UHRF2 might accelerate HCC progression by upregulating ErbB3/Ras/Raf signaling pathway and it might serve as a diagnostic marker and therapeutic target for HCC patients.

Abstract
BACKGROUND AND AIMS The major cause of Hepatocellular carcinoma (HCC) is acute or chronic infection caused by hepatotropic viruses and HBV infection is the main cause. UHRF2, a ubiquitin-protein ligase E3, is associated with cancer development. This study aimed to investigate the connection and mechanism between UHRF2 and HBV-associated HCC. METHODS The expression of UHRF2 in human HBV-positive HCC tissues and paracancerous tissues was detected by western blot and tissue microarray. The effects of UHRF2 on invasion, migration and proliferation were detected in HBV-positive hepatoma cell lines. Furthermore, western blot, immunofluorescence, Co-immunoprecipitation and ubiquitination assays were used to explore the relationship and mechanism between UHRF2 and HBV-associated HCC. RESULTS HBV-positive HCC tissues had higher UHRF2 expression levels than adjacent non-tumor tissues. The HBV-positive HCC patients with a low UHRF2 level in cancer tissues had longer overall and recurrence-free survival compared with those with a high UHRF2 level. UHRF2 induced invasion, migration and proliferation in human HBV-positive HCC cell lines HepG2.2.15 and Hep AD38(-). HBx, an encoding protein of HBV, maintained the stability of UHRF2 by blocking the ubiquitination of UHRF2. HBx up-regulated CDK2 expression through ETS1. UHRF2 bound to CDK2 directly and enhanced UHRF2 phosphorylation at serine 643. CONCLUSIONS These results suggest that HBx-ETS1-CDK2-UHRF2 pathway plays an important role in the pathogenesis of HBV-associated HCC and represents new therapeutic targets for human HCC.

Abstract
The current study determined the molecular fingerprints of TNBCs of women from kenya (KE) and compared them with those of African–American (AA) and Caucasian (CA) women. RNA sequencing analysis highlights the role of molecular alterations in TNBCs and the potential benefit of targeting pathways in this disease for the KE population as compared to AAs and CAs. The dysregulated genes and signaling pathways could contributes to the aggressive phenotypes of TNBCs of KE women.
Purpose : Triple-negative breast cancer (TNBC) patients of various ethnic groups often have discrete clinical presentations and outcomes. Women of African descent have a disproportionately higher chance of developing TNBCs. The aim of the current study was to establish the transcriptome of TNBCs from Kenyan (KE) women of Bantu origin and compare it to those TNBCs of African-Americans (AA) and Caucasians (CA) for identifying KE TNBC-specific molecular determinants of cancer progression and potential biomarkers of clinical outcomes. Patients and Methods : Pathology-confirmed TNBC tissues from Kenyan women of Bantu origin (n = 15) and age and stage range matched AA (n = 19) and CA (n = 23) TNBCs of patients from Alabama were included in this study. RNA was isolated from paraffin-embedded tissues, and expression was analyzed by RNA sequencing. Results : At clinical presentation, young KE TNBC patients have tumors of higher stages. Differential expression analysis identified 160 up-regulated and 178 down-regulated genes in KE TNBCs compared to AA and CA TNBCs. Validation analyses of the TCGA breast cancer data identified 45 KE TNBC-specific genes that are involved in the apoptosis (ACTC1, ERCC6 and CD14), cell proliferation (UHRF2, KDM4C, UHMK1, KCNH5, KRT18, CSF1R and S100A13), and Wnt signaling (BCL9L) pathways. Conclusions : In this study, we identified biomarkers that are specific for KE TNBC patients of Bantu origin. Further study with a larger sample size of matched tumors could confirm our findings. If biologically confirmed, these molecular determinants could have clinical and biological implications and serve as targets for development of personalized therapeutics for KE TNBC patients.

Abstract
PURPOSE SET binding protein 1 (SETBP1) has involved in cancer pathogenesis like leukemic malignancies and breast cancer. But the role and the underlying mechanism in NSCLC remain unclear. METHODS RT-PCR and western blotting were used for determining the expression level of SETBP1 in NSCLC. The clinical values of SETBP1 expression were evaluated by tissue microarray and immunohistochemistry. CCK-8, transwell and Matrigel assays were used to assess NSCLC cells proliferation, migration and invasion ability. The analysis of EMT markers was carried out by RT-PCR, western blotting and immunofluorescence. Bioinformatics analysis revealed the relationship between SETBP1 expression and tumor-associated immune cells. RESULTS SETBP1 expression was significantly downregulated in NSCLC tissues than matched peri-tumors and NSCLC patients with the decreased level of SETBP1 had worse OS. Downregulation of SETBP1 expression induced EMT to promote NSCLC cells proliferation, migration and invasion by the activation of ERK1/2 signal pathway. Aberrant SETBP1 expression was companied by disordered immune status of NSCLC patients and might be involved in regulation of polarization of tumor-associated macrophages. CONCLUSION SETBP1 can act as a tumor suppressor to reduce the progression of NSCLC and can be used for a prognostic biomarker in NSCLC. Aberrant SETBP1 expression was companied by disordered immune status of NSCLC patients.

Abstract
Epigenetic alternations concern heritable yet reversible changes in histone or DNA modifications that regulate gene activity beyond the underlying sequence. Epigenetic dysregulation is often linked to human disease, notably cancer. With the development of various drugs targeting epigenetic regulators, epigenetic-targeted therapy has been applied in the treatment of hematological malignancies and has exhibited viable therapeutic potential for solid tumors in preclinical and clinical trials. In this review, we summarize the aberrant functions of enzymes in DNA methylation, histone acetylation and histone methylation during tumor progression and highlight the development of inhibitors of or drugs targeted at epigenetic enzymes.

Abstract
AIMS To unveil the role of EI2BL in non-small cell lung cancer (NSCLC) and the relationship between expression of EI2BL and the prognosis of patients with NSCLC. METHODS Immunohistochemistry (IHC), western blot analysis, immunofluorescence and real-time quantitative PCR (RT-qPCR) were used to evaluate EI2BL protein and mRNA levels in NSCLC and corresponding peritumour tissues. Cell Counting Kit-8, transwell assay and wound healing assay were used to analyse the abilities of cell proliferation, invasion and migration. In addition, the analysis of epithelial-mesenchymal transition (EMT) markers was also assessed by western blot analysis, RT-qPCR and immunofluorescence. Tissue micro-array analysis of 200 NSCLC cases was used to assess the relationship between EI2BL expression and clinicopathological characteristics. Moreover, the prognostic role of EI2BL in 200 patients with NSCLC was evaluated by Cox regression models and Kaplan-Meier methods. RESULTS Elevated EI2BL expression was more common in NSCLC tissues than paired peritumour tissues in both mRNA and protein level. EI2BL promoted the proliferation, invasion and migration of NSCLC cells. In addition, aberrant EI2BL expression might modulate the expression of key molecules of EMT by ERK1/2 signal pathway. The expression of EI2BL was significantly associated with tumour stage, lymph node metastasis and tumour size. Moreover, higher expression of EI2BL in patients with NSCLC had a poor overall survival rate. CONCLUSIONS Our study illustrated that elevated expression of EI2BL promoted NSCLC cell proliferation, migration and invasion and EI2BL overexpression may be a reliable biomarker of poor prognosis.
