The invention relates to logic-gate-based Type II or Type V CRISPR-Cas constructs and methods for modifying gene expression using the CRISPR-Cas constructs and CRISPR-Cas effector proteins.

The present invention refers to a fusion protein or a protein complex comprising a DNA binding protein (DnaBP), a nucleobase modifying protein (NMP), and a Base Excision Repair associated protein (BERAP. Also, described herein are a method of replacing a cytosine with a guanine on a DNA strand in a cell and a method of treating a subject having or suspected of having a disease or disorder.

The disclosure is directed to compositions and methods comprising genetically engineered fibroblasts for inhibiting progression of a cancerous tumor.

Disclosed herein are cartridges for transfecting cells and/or generating clonal populations of cells comprising: a) a first compartment configured for performing cell transfection, wherein the first compartment comprises a first inlet configured for introduction of a cell sample; b) a second compartment configured for performing cell selection, wherein an inlet of the second compartment is operably coupled to an outlet of the first compartment, and wherein the second compartment further comprises at least one optically-transparent wall and an outlet that is operably coupled to an intermediate cell removal port; and c) a third compartment configured for performing cell expansion, wherein an inlet of the third compartment is operably coupled to the outlet of the second compartment.

RNA-guided programmable cytosine and adenine base editors are a powerful class of genome editing tool for the introduction of localized base transitions without generating a double-stranded DNA break. Base editors (BE) have an optimal window of activity relative to the PAM recognized by the Cas9 enzyme and these constructs are strand selective. Here we demonstrate that fusion of a programmable DNA-binding domain (pDBD) or another Cas9 orthologue to spCas9-BE, we can produce an RNA-programmable Cas9-BE-pDBD chimera or Cas9-BE-Cas9 chimeras with dramatically improved activities and increased targeting range. Cas9-pDBD or Cas9-Cas9 fusion base editors display an expanded targeting repertoire and achieve highly specific genome editing, which can be tailored to achieve extremely precise genome editing at nearly any genomic locus.
