circRNA-disease information
Expression pattern:
DN
Associated gene: Bcl-2, Cyclin D1, Vimentin, E-cadherin
Associated microRNA: hsa-miR-1200, hsa-miR-492, hsa-miR-665
Biological function: hsa_circ_0036988 suppresses OSCC cell proliferation, migration, invasion and EMT-related malignant behavior; low expression is associated with lymph node metastasis.
Molecular mechanism: hsa_circ_0036988 regulates the EMT process and alters EMT-related protein expression; bioinformatics predicted potential miRNA targets hsa-miR-1200, hsa-miR-492 and hsa-miR-665, but the detailed regulatory mechanism requires further experimental study.
Biological pathway or process:

proliferation (inhibits); migration (inhibits); invasion (inhibits); metastasis (inhibits); EMT (inhibits); ceRNA regulation (other)

Detected method:
Q
S
Validation methods:

RT-qPCR; Clinical Sample Validation; Transfection; CCK8; EdU Staining; Transwell Assay; Western Blot; ROC Analysis; Bioinformatics Analysis; RNA-seq

Clinical significance:

Low hsa_circ_0036988 expression was correlated with lymph node metastasis, and ROC analysis suggested diagnostic value as an OSCC indicator.

Description:

This study identifies hsa_circ_0036988 as a down-regulated circRNA in OSCC tissues and cell lines. Functional experiments indicate that hsa_circ_0036988 acts as a tumor suppressor by inhibiting proliferation, migration, invasion and EMT-related changes, while low expression correlates with lymph node metastasis and has potential diagnostic value.

Confidence score:

0.6758
