hsa-mir-133a-3p

This part is the sequence for hsa-miR-133a-3p, a miRNA isolated from Homo sapiens. This miRNA acts as an upregulated biomarker for coronary artery disease (Kaur et al., 2020), and is therefore potentially useful for the early detection of this condition. Similar to BBa_K4245006, hsa-miR-133a-3p, or miRNA-133a-3p, is seen to increase in blood circulation potentially hours and days before a myocardial infarction, even before Troponin T is increased in circulation, and it is also related with cardiac-specific muscle lineage (Xiao et al., 2019). Thus, both biomarkers increase the sensitivity of our biosensors, as both miRNA-1-3p and miRNA-133a-3p in higher concentrations could indicate a possible heart attack.

The Lambert_GA 2022 team developed a set of padlock probes to use the rolling circle amplification approaches for several miRNAs related to CAD. This miRNA is used as the basis for BBa_K4245103 and BBa_K4245110, the 3' arm for hsa-miR-133a-3p and 5' arm for hsa-miR-133a-3p, and as the target sequence for BBa_K4245204 and BBa_K4245205 the hsa-miR-133a-3p RCA Padlock Probe and the hsa-miR-133a-3p RCT Padlock Probe.

When using rolling circle amplification (RCA), the miRNA binds to the padlock. A rolling circle product (RCP) is produced from BBa_K4245131 (Middle Sequence), which is then detected by the linear probes BBa_K4245130 (Fluorophore) and BBa_K4245132 (Quencher). When these parts bind to the RCP, the fluorescence decreases. Therefore, lower fluorescence is indicative of greater miRNA concentrations.
