circRNA-disease information
Expression pattern:
DN
Associated gene: CPSF3, UBXN7, E2F1
Associated microRNA: miR-622, miR-1247
Biological function: Acts as a miRNA sponge/storage component; CPSF3-mediated reduction of this circRNA is linked to disrupted miRNA-mediated gene silencing and increased expression of miRNA target genes in HCC cells.
Molecular mechanism: CPSF3 enhances PAS-dependent pre-mRNA cleavage, shifting processing from circRNA (hsa_circ_0001380) to linear mRNA (UBXN7), reducing circRNA-associated miRNAs (miR-622/miR-1247) and thereby impairing miRNA-mediated silencing of target genes such as E2F1.
Biological pathway or process:

ceRNA regulation (other)
Detected method:
Q
S
Validation methods:

RNA-seq; RT-qPCR; Clinical Sample Validation; RNA Pull-Down; Dot Blot
Clinical significance:

-
Description:

In HCC cells, CPSF3 suppresses hsa_circ_0001380 biogenesis (PAS-dependent shift from circRNA to linear UBXN7 mRNA). Reduced hsa_circ_0001380 is associated with decreased levels of its bound miRNAs (miR-622/miR-1247) and impaired miRNA-mediated gene silencing (e.g., E2F1).
