Abstract
The communication between tumor-derived exosomes and macrophages plays an important role in facilitating the progression of tumors. However, the regulatory mechanisms by which exosomes regulate tumor progression in esophageal squamous cell carcinoma (ESCC) have not been fully elucidated. We constructed a coculture system containing an ESCC cell line and macrophages using a Transwell chamber. We isolated exosomes from the conditioned medium of cancer cells, and characterized them with transmission electron microscopy and western blotting and used then to treat macrophages. We used co-immunoprecipitation to evaluate the interaction between hyaluronidase 1 (HYAL1) and Aurora B kinase (AURKB). We evaluated HYAL1 and AURKB expression in tissues and cells with quantitative reverse-transcription polymerase chain reaction (RT-qPCR) and western blotting. We used RT-qPCR, enzyme-linked immunosorbent assay (ELISA) and flow cytometry to detect macrophage polarization. We assessed cell viability, invasion and migration with the cell counting kit-8 (CCK-8), Transwell and wound healing assays. HYAL1 was highly expressed in ESCC tissues and cells and cancer cell-derived exosomes, and exosomes can be delivered to macrophages through the cancer cell-derived exosomes. The exosomes extracted from HYAL1-overexpressed ESCC cells suppressed M1 macrophage polarization and induced M2 macrophage polarization, thereby promoting ESCC cell viability, invasion and migration. HYAL1 silencing in ESCC cells produced the opposite effects on macrophage polarization and cancer cell functions. We found that HYAL1 interacted with AURKB and further activated the phosphoinositide 3-kinase (PI3K)/AKT signaling pathway in macrophages. In conclusion, ESCC-derived exosomes containing HYAL1 facilitate M2 macrophage polarization by targeting AURKB to active the PI3K/AKT signaling pathway, which in turn promotes ESCC progression.

Abstract
Aurora kinase B (AURKB) overexpression promotes tumor initiation and development by participating in the cell cycle. In this study, we focused on the mechanism of AURKB in hepatocellular carcinoma (HCC) progression and on AURKB's value as a diagnostic and prognostic biomarker in HCC. We used data from The Cancer Genome Atlas (TCGA) and the Gene Expression Omnibus (GEO) to analyze AURKB expression in HCC. We found that the expression levels of AURKB in HCC samples were higher than those in the corresponding control group. R packages were used to analyze RNA sequencing data to identify AURKB-related differentially expressed genes (DEGs), and these genes were found to be significantly enriched during the cell cycle. The biological function of AURKB was verified, and the results showed that cell proliferation was slowed down and cells were arrested in the G2/M phase when AURKB was knocked down. AURKB overexpression resulted in significant differences in clinical symptoms, such as the clinical T stage and pathological stage. Kaplan-Meier survival analysis, Cox regression analysis, and Receiver Operating Characteristic (ROC) curve analysis suggested that AURKB overexpression has good diagnostic and prognostic potential in HCC. Therefore, AURKB may be used as a potential target for the diagnosis and cure of HCC.

Abstract
Cell cycle regulators play pivotal roles as their dysregulation, leads to atypical proliferation and intrinsic genomic instability in cancer cells. Abnormal expression and functioning of Aurora kinase B (AURKB) are associated with cancer pathogenesis and thus exploited as a potential therapeutic target for the development of anti-cancer therapeutics. To identify effective AURKB inhibitors, a series of polyphenols was investigated to check their potential to inhibit recombinant AURKB. Their binding affinities were experimentally validated through fluorescence binding studies. Enzyme inhibition assay revealed that Mangiferin and Baicalin significantly inhibited AURKB activity with an IC50 values of 20.0 μM and 31.1 μM, respectively. To get atomistic insights into the binding mechanism, molecular docking and MD simulations of 100 ns were performed. Both compounds formed many non-covalent interactions with the residues of the active site pocket of AURKB. In addition, minimal conformational changes in the structure and formation of stable AURKB-ligand complex were observed during MD simulation analysis. Finally, cell-based studies suggested that Baicalin exhibited in-vitro cytotoxicity and anti-proliferative effects on lung cancer cell lines. Conclusively, Baicalin may be considered a promising therapeutic molecule against AURKB, adding an additional novel lead to the anti-cancer repertoire.
