Abstract

The conventional strategy for cancer gene therapy offers limited control of specificity and efficacy. A possible way to overcome these limitations is to construct logic circuits. Here we present modular AND gate circuits based on CRISPR-Cas9 system. The circuits integrate cellular information from two promoters as inputs and activate the output gene only when both inputs are active in the tested cell lines. Using the luciferase reporter as the output gene, we show that the circuit specifically detects bladder cancer cells and significantly enhances luciferase expression in comparison to the human telomerase reverse transcriptase-renilla luciferase construct. We also test the modularity of the design by replacing the output with other cellular functional genes including hBAX, p21 and E-cadherin. The circuits effectively inhibit bladder cancer cell growth, induce apoptosis and decrease cell motility by regulating the corresponding gene. This approach provides a synthetic biology platform for targeting and controlling bladder cancer cells in vitro.

  • In bladder cancer cells, Cas9 and sgRNAs were both expressed, mutating the LacI gene and abrogating its suppression on the effector gene, leading to bladder cancer cell-specific expression of the effector.

    “In bladder cancer cells, Cas9 and sgRNAs were both expressed, mutating LacI gene and abrogating its suppression on the effector gene, leading to bladder cancer cell-specific expression of the effector (figure 2C, right).”

  • Liu et al used CRISPR-Cas9-mediated bladder cancer cell-specific genome editing using an AND logic gate.

    “An example of therapeutic genome manipulations comes from study by Liu et al 47 in which CRISPR-Cas9-mediated bladder cancer cell-specific genome editing using an AND logic gate (figure 2).”

  • In the Liu et al study, effector genes p21, E-cadherin and Bax led to cancer-specific growth inhibition, migration suppression and apoptosis, respectively.

    “In this study, the effector genes were p21, E-cadherin and Bax (BCL2-associated X), leading to cancer-specific growth inhibition, migration suppression and apoptosis, respectively.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
