This part is the sequence for hsa-miR-133a-3p, an miRNA isolated from <i> Homo sapiens </i>. 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 <partinfo>BBa_K4245006</partinfo>, 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, as 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 concentration could indicate a possible heart attack. | This part is the sequence for hsa-miR-133a-3p, an miRNA isolated from <i> Homo sapiens </i>.

hsa-mir-133a-3p
This part is the sequence for hsa-miR-133a-3p, an 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, as 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 concentration could indicate a possible heart attack.
The Lambert_GA 2022 team developed a set of padlock probes to be used with 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.
