Advances in quantifying circulatory microRNA for early disease detection

Author(s): Cheong JK, Tang YC, Zhou LH, Cheng H, and Too HP. Current Opinion in Biotechnology 2022 Jan 6; 74:256–262


Summary: Key to the delivery of preventive healthcare is the clinical adoption of novel assays that enable early disease detection. This review article discusses the clinical utility and validation of miRNA-based molecular diagnostics for early disease detection through large-cohort studies and key considerations for developing multi-analyte clinical assays. 

Development and validation of a circulating microRNA panel for the early detection of breast cancer

Author(s): Zou R, Loke SY, Tang YC, Too HP, Zhou L, Lee ASG, and Hartman M. British Journal of Cancer 2022 Jan 10


Summary: This paper describes the largest comprehensive, multi-center study to date involving diverse ethnic groups, for the identification of circulating miRNAs for breast cancer screening. The panel detects breast cancer in Caucasian and Asian populations, including pre-malignant lesions (stage 0) and early-stage (stages 1-2) cancers.

Summary: Discovery, development, and validation of a serum 5-miRNA biomarker panel for early detection of non-small call lung cancer (NSCLC). The panel was validated to detect 81.3% of all NSCLC patients, including 83.0% of Stage 1 tumours.

High-performance quantification of mature microRNAs by real-time RT-PCR using deoxyuridine-incorporated oligonucleotides and hemi-nested primers

Author(s): Wan G, Lim QE, Too HP. RNA 2010 Jul;16(7):1436-45.


Summary: Paper describing the development of a high-performance real-time RT-PCR assay that allows specific and rapid quantification of existing and novel miRNAs using a fast thermocycling profile. The assay had a wide dynamic range (more than 7 orders of magnitude) and was capable of detecting miRNAs from as little as 1 picogram of total RNA (or as few as 10 cells).
