circRNA-disease information
Expression pattern:
DN
Associated gene: Klotho
Associated microRNA: miR-199a-5p
Biological function: circ-ITCH suppresses gastric cancer progression by inhibiting proliferation, migration, invasion, EMT and metastasis; it also has partial effect on anticancer chemotherapy.
Molecular mechanism: circ-ITCH acts as a miR-199a-5p sponge and increases Klotho expression, thereby affecting EMT and metastasis in gastric cancer.
Biological pathway or process:

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

Detected method:
Q
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; Sanger Sequencing; RT-qPCR; Clinical Sample Validation; Transfection; CCK8; Colony Formation Assay; Transwell Assay; Western Blot; Nuclear-Cytoplasmic Fractionation; Luciferase Reporter Assay; Bioinformatics Analysis; ROC Analysis

Clinical significance:

circ-ITCH is related to invasion depth and may serve as a molecular biomarker for diagnosis of gastric cancer; it is proposed as a potential biomarker and target for diagnosis and therapy.

Description:

circ-ITCH is down-regulated in gastric cancer tissues, cell lines and serum-derived exosomes. It functions as a tumor suppressor by sponging miR-199a-5p and increasing Klotho expression, thereby inhibiting EMT, migration, invasion, metastasis and proliferation. Clinically, low circ-ITCH is associated with invasion depth and circ-ITCH may serve as a biomarker and therapeutic target for gastric cancer.

Confidence score:

0.8314
