Popis: Abstract Background CircRNAs are functional in cancer-related processes and are promising candidates for cancer prognostic biomarkers. The study aimed to evaluate the functional and clinical significance of has_circ_0001944 in colorectal cancer (CRC), including predictive value for overall survival (OS) and recurrence-free survival (RFS), and its effect on cell growth and metastasis. Methods This retrospective study included 133 patients with CRC. The expression of has_circ_0001944 in tissues and cells was quantified by real-time quantitative reverse transcription PCR. Receiver operating characteristics and Kaplan–Meier survival analysis were used to assess the significance of has_circ_0001944 as a prognostic marker, and its reliability was validated using multivariate regression analysis. Subsequently, XTT, transwell migration, and modified-transwell invasion assays were used to determine the behavior of the CRC cells in response to has_circ_0001944 inhibition. Results Results of the qRT-PCR showed upregulation of has_circ_0001944 in the CRC samples compared to the normal samples. High has_circ_0001944 expression indicated shorter OS and RFS, comes down to poor prognosis. Multivariate regression analysis showed that elevated has_circ_0001944 increased the risk of death or recurrence and is a valuable prognostic factor. Following the has_circ_0001944 inhibition, the proliferation, migration and invasion of the CRC cells were reduced. miR-548b-3p was target miRNA of has_circ_0001944. Conclusion Up-regulation of has_circ_0001944 is associated with a poor prognosis of CRC. has_circ_0001944 downregulation can slow the progression of CRC partly by targeting miR-548b-3p.
