circRNA-disease information
Expression pattern:
DN
Associated gene: -
Associated microRNA: -
Biological function: Lower circ6229/METTL3 ratio is associated with higher proliferation in CRC tissues.
Molecular mechanism: Negative association between circRNA/linRNA ratio and Ki-67 proliferation index; no specific miRNA mechanism tested for circ6229.
Biological pathway or process:

proliferation (inhibits)
Detected method:
Q
S
Validation methods:

RT-qPCR; RNase R Treatment; Clinical Sample Validation; IHC (Immunohistochemistry); RNA-seq
Clinical significance:

-
Description:

circ6229 (from METTL3) is decreased in CRC and its circ6229/METTL3 ratio is significantly negatively correlated with Ki-67 proliferation, supporting the study’s model that circRNAs are diluted in proliferating cancer cells.
Confidence score:

0.5662
