circRNA-disease information
Expression pattern:
UN
Associated gene: PKR
Associated microRNA: -
Biological function: AAV-delivered circCAMSAP1(2,3) dampens PKR activation, reduces proinflammatory cytokines, decreases Abeta plaques and Tau pathology, alleviates gliosis and neuronal loss, and improves spatial learning and memory in AD mouse models.
Molecular mechanism: circCAMSAP1(2,3) is a human ds-cRNA containing three short duplex regions; as a ds-cRNA aptamer it suppresses PKR activation, thereby reducing neuroinflammation and AD-related pathological phenotypes.
Biological pathway or process:

immune regulation (inhibits); inflammation (inhibits); proliferation (inhibits); other pathway/process (inhibits)

Detected method:
Q
B
Validation methods:

Northern Blot; RT-qPCR; IF (Immunofluorescence); ELISA; Western Blot; In Vivo Animal Model

Clinical significance:

-

Description:

Human circCAMSAP1(2,3) was used as an independent ds-cRNA aptamer to test whether therapeutic effects were not sequence-specific to circPOLR2A. AAV delivery of circCAMSAP1(2,3) reduced PKR activation and neuroinflammation, alleviated AD-related pathology, and improved learning and memory in 5xFAD and PS19 mouse models.

Confidence score:

0.4636
