circRNA-disease information
Expression pattern:
DN
Associated gene: HNRNPC, U2AF2, AGO2, ELAVL1, HNRNPA1, TARDBP
Associated microRNA: -
Biological function: inhibits proliferation; inhibits migration/invasion; inhibits colony formation; inhibits tumour growth
Molecular mechanism: Predicted to act via interactions with microRNAs and RNA-binding proteins (protein traps/miRNA sponges) based on bioinformatic analyses; no specific miRNA experimentally validated.
Biological pathway or process:

proliferation (inhibits); migration (inhibits); invasion (inhibits); metastasis (inhibits); other pathway/process (other)

Detected method:
Q
M
Validation methods:

Microarray; RT-qPCR; Sanger Sequencing; RNase R Treatment; Clinical Sample Validation; ROC Analysis; Transfection; CCK8; Wound Healing Assay; Transwell Assay; Colony Formation Assay; In Vivo Animal Model

Clinical significance:

Lower serum exosomal circ_0061407 levels were associated with advanced pathological staging and distant metastasis; shows diagnostic value for NSCLC (ROC AUC reported).

Description:

Serum exosomal circ_0061407 is down-regulated in NSCLC and acts as a tumor-suppressive circRNA: its overexpression (including exosome-mediated delivery) inhibits NSCLC-related proliferation, migration/invasion, colony formation, and xenograft tumor growth. It shows diagnostic potential for NSCLC and correlates with distant metastasis/advanced stage; mechanisms were mainly predicted via miRNA/mRNA networks and RBP interactions.

Confidence score:

0.7588

Other information
Title:

Exosome-transported circ_0061407 and circ_0008103 play a tumour-repressive role and show diagnostic value in non-small-cell lung cancer.
