circRNA-disease information
Expression pattern:
DN
Associated gene: ATG5-ATG12, ATG7, LC3-II
Associated microRNA: -
Biological function: Inhibits PCa proliferation by blocking autophagy; knockdown promotes proliferation and tumor growth.
Molecular mechanism: Knockdown enhances autophagy (increased ATG5-ATG12, ATG7, LC3-II; increased autophagy flux), and autophagy inhibition (CQ) rescues the proliferation promoted by hsa_circ_0001747 knockdown.
Biological pathway or process:

autophagy (inhibits); proliferation (inhibits)

Detected method:
Q
Validation methods:

RT-qPCR; RNase R Treatment; Sanger Sequencing; Back-Splice Junction PCR / divergent primers PCR; Nuclear-Cytoplasmic Fractionation; Transfection; CCK8; Colony Formation Assay; Western Blot; IF (Immunofluorescence); In Vivo Animal Model

Clinical significance:

High expression of hsa_circ_0001747 predicts longer BCR-free time and is a favorable prognostic factor for BCR in PCa.

Description:

hsa_circ_0001747 (from MKLN1) is down-regulated in prostate cancer and acts as a protective factor: higher expression predicts longer BCR-free survival. Functionally, its knockdown enhances autophagy flux and promotes PCa cell proliferation and xenograft growth, while autophagy inhibition (CQ) mitigates this effect.

Confidence score:

0.6634
