circRNA-disease information
Expression pattern:
DN
Associated gene: AGO2, ATF3, BTG2, DUSP1, EGR1, FGF2, FOSB, GNAI1, GNAO1, GNAZ, GNG7, ITPKB, ITPR1, JUND, NR4A3, PRKCB
Associated microRNA: -
Biological function: May function as ceRNA (miRNA sponge) in gastric cancer; included in circRNA-miRNA-mRNA networks and may modulate hub gene expression when overexpressed with other circRNAs.
Molecular mechanism: Predicted circRNA-miRNA interactions (MREs) with AGO2 binding evidence; ceRNA network construction with downstream target mRNAs.
Biological pathway or process:

ceRNA regulation (other); MAPK (other); PI3K/AKT (other)
Detected method:
Q

M
Validation methods:

Microarray; RNA-seq; Back-Splice Junction PCR / divergent primers PCR; Sanger Sequencing; RNase R Treatment; RT-qPCR; Nuclear-Cytoplasmic Fractionation; Bioinformatics Analysis; Transfection
Clinical significance:

-
Description:

hsa_circ_0001438 is down-regulated in gastric cancer and predominantly localized in the cytoplasm. The study supports a proposed ceRNA role through predicted miRNA binding (with AGO2 binding site evidence) within circRNA-miRNA-mRNA networks enriched for MAPK and PI3K-AKT pathways.
Confidence score:

0.6223
