Disease Name: | Osteosarcoma |
Sample: | OS tissues |
Dysfunction Pattern: | Interaction(miR-532-5p/PTEN axis) |
Validated Method: | IHC//Western Blot//ISH//Transfection//qPCR//CCK8//FISH//RIP//PCR//IP//Transwell Assay//IF |
Description: | We found that circROCK1-E3/E4, regulated by the well-known RNA-binding protein quaking (QKI), was downregulated in OS and correlated with unfavorable clinical features of patients with OS.Mechanistically, circROCK1-E3/E4 suppressed proliferation and migration by upregulating phosphatase and tensin homolog (PTEN) through microRNA-532-5p (miR-532-5p) sponging. |
Causality: | Yes |
Causal Description: | Functional proliferation and cell motility assays indicated that circROCK1-E3/E4 serves as a tumor suppressor in OS cells. In the constructed nude mouse model, circROCK1-E3/E4 inhibited tumor growth and lung metastasis in vivo. |
Clinical-realted Application: | We found that circROCK1-E3/E4, regulated by the well-known RNA-binding protein quaking (QKI), was downregulated in OS and correlated with unfavorable clinical features of patients with OS. |
