Summary
This summary is machine-generated.Circular RNAs (circPVT1) promote osteosarcoma progression by regulating the miR-490-5p/HAVCR2 axis. Inhibiting circPVT1 reduces cell migration and invasion, offering a potential therapeutic strategy for osteosarcoma.
Area Of Science
- Oncology
- Molecular Biology
- Genetics
Background
- Circular RNAs (circRNAs) are implicated in osteosarcoma development.
- The specific role of circPVT1 in osteosarcoma pathogenesis requires elucidation.
Purpose Of The Study
- To investigate the molecular mechanism of circPVT1 in osteosarcoma cells.
- To determine the regulatory relationship between circPVT1, miR-490-5p, and HAVCR2 in osteosarcoma.
Main Methods
- Quantitative real-time PCR (qRT-PCR) for circPVT1 expression analysis.
- In vitro assays including wound healing, transwell migration, and Matrigel invasion assays.
- Fluorescence in situ hybridization, Western blot, bioinformatics, dual-luciferase reporter assays, and rescue experiments to elucidate molecular mechanisms.
Main Results
- CircPVT1 expression was significantly upregulated in osteosarcoma cell lines compared to controls.
- Depletion of circPVT1 inhibited osteosarcoma cell migration and invasion.
- CircPVT1 acts as a miR-490-5p sponge, directly targeting HAVCR2 and upregulating its expression, thereby promoting cell migration and invasion.
Conclusions
- CircPVT1 promotes osteosarcoma cell migration and invasion by modulating the miR-490-5p/HAVCR2 signaling pathway.
- CircPVT1 represents a potential therapeutic target for osteosarcoma treatment.

Invadosome is a broad category of cell surface structures with proteolytic activity that degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand RNA genome. Its genome consists of four main open...
Cell polarity is the asymmetric distribution of cellular and membrane components, making one side of the cell different from the other. This polarity is essential to many processes such as embryogenesis, axon migration, glucose transport across epithelial cells, and directional cell migration. A migrating cell responds to intracellular or extracellular signals via molecular cascades that reorganize the actin cytoskeleton to establish this polarity. In these cells, the Rho family proteins Cdc42,...
Cell migration is a process by which the cells move from one location to another, playing an essential role in embryological development, repair and regeneration, immune response, and metastasis. Cells migrate in response to chemical or mechanical signals generated by specific organs or tissues. The overall mechanism includes three steps - polarization, protrusion, and release. Polarization involves the formation of a distinct cell front and rear, which determines the direction of movement.
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
A migrating cell changes its shape during the cyclic events of attachment and detachment from the substratum and repositions the cell organelles correspondingly. These complex events are orchestrated by the dynamic cytoskeletal network comprising actin filaments, intermediate filaments, and microtubules. Cytoskeletal crosstalk — the direct and indirect communication between the different components — is crucial for this coordination. Direct communication involves various linker...
