Biomarker Filtration
Steps Of Our Biomarker filtration
Design
Our design aims to compare the function of both circuits at regulating non-coding RNAs
CRISPR circuit | ceRNA circuit |
BBa_K2217026 |
BBa_K2217025 |
Fig-1 Composite Part BBa_K2217018
Part BBa_K2217018 was composed of U6 (BBa_K2217002) as a promoter for gRNA (BBa_K2217003)(Designed using MIT CRISPR web tool according to the addgene protocol).[1][2] The gRNA needs a scaffold to guide the Cas9 (BBa_K2217004) and finally it was terminated by SV40 poly(A) signal Termination (BBa_K2217005).
Fig-2 Composite Part BBa_K2217019
Part BBa_K2217019 was composed of CMV Enhancer as well as CMV Promoter (BBa_K2217000 and BBa_K2217006 respectively) as constitutive promoters to enhance the transcription process of the Cas9 (BBa_K1218011) part which was transcribed using T7 Promoter (BBa_K2217007) following Protocol[3]. The design aimed at generating Homology Directed Repair instead of Non-Homologous end Joining repair of Cas9 by knocking in the circular RNA as a Competing endogenous RNA enhancing its transcription to regulate miRNA action, so we designed Homology repair template (BBa_K2217009) to be transfected on a separate donor vector then terminated with CYC1 terminator(BBa_K2217008).
Fig-3 Composite Part BBa_K2217020
In order to enhance transcription of the circular RNA as a competing endogenous RNA in a ceRNA network, we used the CAG promoter composed of CMV enhancer and Chicken B-actin Promoter (BBa_K2217013) while circular RNA (hsa-circ-0000064) was submitted to the registry after biomarker filtration using bioinformatics databases demonstrated at our biomarker filtration page (BBa_K2217001). Finally it was terminated by SV40 poly(A) signal Termination (BBa_K2217005).
Fig-4 Composite Part BBa_K2217022
Part BBa_K2217022 was composed of CMV Enhancer as well as CMV Promoter (BBa_K2217000 and BBa_K2217006 respectively) as constitutive promoters to enhance the transcription process of the laci that was submitted (Ba_K2217012). We also improved the fragment’s characterization by adding the miRNA binding site of the miRNA mir-1825 as determined computationally using circ interactome database [4] where we hypothesised its function as a trigger for miRNA binding and synthesis. Finally, it was terminated by SV40 poly(A) signal Termination (BBa_K2217005).
Fig-5 Composite Part BBa_K2217023
Part BBa_K2217023 is composed of lac operator (BBa_K2217016) and the lac promoter (BBa_K2217017) as a weak constitutive promoter in a trial to improve characterization of ceRNA network using yfb (BBa_K2217014) detection using flow cytometry. Finally, it was terminated by Poly_gh termination (BBa_K2217015).
All Parts were designed in SBOL format using SBOLDesigner.[5] Sequence editing was performed on Benchling[6] and composites were constructed in syntheticTM Language using cytostudio.[7]
