Biological function: CircMTO1 was used as the target circRNA for an ultrasensitive biosensor and its abnormal expression was used to discriminate cancer cells and breast cancer patient tissues from controls.
Molecular mechanism: The study focuses on a detection mechanism in which circMTO1 triggers proximity ligation-activated recombinase polymerase amplification followed by transcription amplification to generate Spinach RNA aptamers and DFHBI fluorescence; no endogenous disease-regulatory molecular mechanism was tested.
Biological pathway or process:

not specified

Detected method:
Q
Validation methods:

RT-qPCR; Clinical Sample Validation

Clinical significance:

The dysregulation of circMTO1 may act as a potential prognostic marker for breast cancer, and the biosensor can discriminate circMTO1 levels between breast cancer patient tissues and healthy tissues.

Description:

This study used circMTO1 as the model target to develop and validate a label-free ultrasensitive fluorescent biosensor. Endogenous circMTO1 was dysregulated across tested human cancer cell lines and was down-regulated in breast cancer patient tissues compared with healthy tissues, supporting its potential clinical utility as a cancer-related biomarker.

Confidence score:

0.2995
