circRNA-disease information
Expression pattern:
UP
Associated gene: LANA, RTA, TNF
Associated microRNA: miR-K12-10b
Biological function: Functions as an antiviral factor that suppresses KSHV latent and lytic viral gene expression without blocking viral entry; may stimulate host defense pathways.
Molecular mechanism: Predicted viral miRNA binding and antiviral regulation of KSHV gene expression; possible stimulation of host defense pathways and possible regulation of viral transcription through chromatin-related transcription factors.
Biological pathway or process:

viral replication (inhibits); immune regulation (promotes); other pathway/process (other)

Detected method:
Q
S
M
Validation methods:

Back-Splice Junction PCR / divergent primers PCR; RNase R Treatment; RT-qPCR; Microarray; circRNA-seq; Transfection; Bioinformatics Analysis

Clinical significance:

-

Description:

hsa_circ_0001400 is a human circRNA induced by KSHV infection. It suppresses KSHV LANA and RTA expression and acts as an antiviral factor, potentially through viral miRNA binding and stimulation of host defense pathways.

Confidence score:

0.5971
