“… box binding protein‐1 (YB‐1), a member from the cold shock protein family, is implicated in a number of cellular processes . The expression of YB‐1 is significantly elevated in several tumours, such as colon cancer and breast cancer, which is as well closely linked to adverse outcome and early relapsing . It is reported that YB‐1 is notably overexpressed in OS and is reversely regulated by miR‐382‐5p .…”

Circular RNA (circRNA) can modulate the gene expression via sponging microRNA (miRNA) in multiple malignancies. Nevertheless, the detailed function of circ_0001658 in osteosarcoma (OS) and its regulatory mechanism remain elusive.Real-time PCR was carried out to detect the expressions of circ_0001658, miR-382-5p, and Y box-binding protein 1 (YB-1) mRNA in OS tissues. Besides, western blot was done to monitor YB-1 expression in OS cells. Chi-squared test was used to analyse the correlation between circ_0001658 and clinicopathologic characteristics of OS patients. CCK8 assay, colony formation assay, flow cytometry, and transwell assay were performed to determine the function of circ_0001658. Moreover, dualluciferase reporter gene assay was done to verify the targeting relationship between circ_0001658 and miR-382-5p. Compared with adjacent tissues, circ_0001658 displayed a significantly higher expression in OS tissues. Circ_0001658 could facilitate the proliferation, migration, and invasion of OS cells and impede apoptosis by sponging miR-382-5p. Further, circ_0001658 was proved to directly and negatively regulate the expression of miR-382-5 while positively modulate the expression of YB-1. Circ_0001658 promotes the proliferation and metastasis of OS cells via modulating miR-382-5p/YB-1 axis. Significance of the study:In recent years, the expression and function of circular RNA in cancer have been the focus of tumour research. The study on circular RNA helps elucidate the molecular pathology of tumorigenesis and cancer progression.This study demonstrated that circ_0001658 promotes the proliferation and metastasis of OS cells via modulating miR-382-5p/YB-1 axis. To our best knowledge, this work is the first to study the expression and function of circ_0001658 in cancer. K E Y W O R D Scirc_0001658, miR-382-5p, osteosarcoma, YB-1 | INTRODUCTIONOsteosarcoma (OS) is a common primary malignant bone tumour among children and adolescents, frequently diagnosed in the distal femur, the proximal tibia, and the proximal humerus. 1,2 Though multiple treatments offer symptomatic relief and modest improvement in survival for OS patients, the long-term disease-free survival rate of patients remains unfavourable, only 60% to 75%. 3,4 To make matters worse, the 5-year survival rate was only 27% to 55% in patients with local relapsing and distant metastasis treated by the available therapy clinically. 5 Hence, it is imperative to probe into the detailed mechanism of OS.Circular RNA (circRNA) is a novel class of endogenous noncoding RNA, which exists widely and stably in mammalian cells without the function of encoding proteins. 6,7 Circ-RNA, unlike linear RNAs, features a closed-loop structure. 8 This distinctive structure contributes

“…Strong evidence has supported the role of YBX-1 in carcinogenesis related events including uncontrolled cell proliferation, genomic instability, cell immortality and induction of angiogenesis [13] [14]. In breast cancer (BC), YBX-1 is linked to drug resistance and promotion of tumor invasion and metastasis through enhanced epithelial-to-mesenchymal transition (EMT) [15] [16].…”

Objectives: The aim of this study was to assess the levels of Y-box binding protein 1 (YBX-1) and interleukin 6 (IL-6) in the sera of metastatic and non-metastatic breast cancer patients (BC), investigate their clinicopathological significance and to analyze their potential use as biomarkers of breast cancer metastasis. Methods: The study included ninety subjects sub-grouped equally into metastatic BC, non-metastatic BC and healthy volunteers. Serum YBX-1 and IL-6 were quantified using ELISA technique while CA 15-3 was quantified using IRMA kit. Clinical data were collected from patients' records. Results: YBX-1 (p < 0.001), IL-6 (p < 0.001) and CA15-3 (p = 0.017, 0.001) were significantly elevated in metastatic and non-metastatic BC patients compared to healthy controls, however, only YBX-1 (p < 0.001) and IL-6 (p < 0.001) showed a significant difference with cancer metastasis. Generally, YBX-1 and IL-6 were correlated with worse histological grade and late clinical stage in breast cancer patients and they were also associated with axillary lymph nodes involvement and positive vascular invasion in metastatic BC patients. Serum YBX-1 and IL-6 levels were positively correlated to each other (r s = 0.615, p < 0.001) and they showed high sensitivity and specificity compared to CA 15-3 (p < 0.001 and p = 0.004 for YBX-1 and IL-6 respectively) for predicting cancer metastasis. Conclusions: Serum YBX-1 and IL-6 are potential biomarkers of breast cancer patients with significant correlation with bad clinicopathological characteristics. Serum YBX-1 and IL-6 have superior sensitivity and specificity compared to CA15-3 and can serve as potential follow up and prognostic markers.

“…To diagnose and treat colorectal cancer more effectively, an increasing number of researchers have turned their attention to the microscopic mechanism of tumors. In the field of colorectal cancer, these efforts have promoted the development of precision medicine based on the identification of new biomarkers and novel molecularly targeted drugs to improve prognosis (14). Previous studies have shown that tumor cells can adjust protein expression levels through post-transcriptional mechanisms to adapt to local microenvironments (6).…”

Background: RNA binding proteins (RBPs) play an important role in regulating post-transcriptional gene expression and have been reported to be closely associated with the occurrence and development of tumors. However, the effect of RBPs in colon cancer remains unclear.Methods: We downloaded clinical information and transcriptome data of colon adenocarcinoma (COAD) from the The Cancer Genome Atlas database (TCGA) database. After combining this data, we identified differentially expressed RBPs in normal and cancer tissues and subsequently performed Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. Prognosis-related RBPs were identified via Cox regression analysis. The samples were randomly divided into two groups; an experimental group and a control group. A predictive model was constructed by dividing the experimental group into high-and low-risk subgroups based on the scores of the prognostic-related RBPs, and the prognosis of samples in these two subgroups was compared. Then, this model was applied to the control group. Finally, the model results were verified based on an online survival database and the Human Protein Atlas (HPA) database.Results: A total of 469 differentially expressed RBPs were identified in normal and cancer tissues. Ten prognosis-related RBPs were determined by Cox regression analysis. In the prognostic prediction model, the prognosis of high-risk patients in the experimental group was worse than that in the low-risk group, and the same result was obtained in the control group. In addition, the risk score in the Cox regression analysis showed that the model could be used as an independent prognostic factor (P<0.001). The results of the online survival analysis tool, HPA database, and the model were consistent.Conclusions: Some specific RBPs are significantly associated with the prognosis of patients with COAD, and this finding may provide important information for the future diagnosis and treatment of patients with COAD.
