Developments in the tools and methodologies of synthetic biology. [PDF]

, 2014
Synthetic biology is principally concerned with the rational design and engineering of biologically based parts, devices, or systems. However, biological systems are generally complex and unpredictable, and are therefore, intrinsically difficult to ...

DNA targeting by compact Cas9d and its resurrected ancestor

Nature Communications
Type II CRISPR endonucleases are widely used programmable genome editing tools. Recently, CRISPR-Cas systems with highly compact nucleases have been discovered, including Cas9d (a type II-D nuclease).

Mitigation of off-target toxicity in CRISPR-Cas9 screens for essential non-coding elements. [PDF]

, 2019
Pooled CRISPR-Cas9 screens are a powerful method for functionally characterizing regulatory elements in the non-coding genome, but off-target effects in these experiments have not been systematically evaluated.

CAS9 is a genome mutator by directly disrupting DNA-PK dependent DNA repair pathway. [PDF]

, 2020
With its high efficiency for site-specific genome editing and easy manipulation, the clustered regularly interspaced short palindromic repeats (CRISPR)/ CRISPR associated protein 9 (CAS9) system has become the most widely used gene editing technology in ...

Dramatic Improvement of CRISPR/Cas9 Editing in Candida albicans by Increased Single Guide RNA Expression

mSphere, 2017
The clustered regularly interspaced short palindromic repeat system with CRISPR-associated protein 9 nuclease (CRISPR/Cas9) has emerged as a versatile tool for genome editing in Candida albicans.

Targeting non-coding RNAs in Plants with the CRISPR-Cas technology is a challenge yet worth accepting

Frontiers in Plant Science, 2015
Non-coding RNAs (ncRNAs) have emerged as versatile master regulator of biological functions in recent years. MicroRNAs (miRNAs) are small endogenous ncRNAs of 18-24 nucleotides in length that originates from long self-complementary precursors.

AcrIIA19 binds to the WED domain and inhibits various Cas9 orthologs at multiple stages

Communications Biology
Anti-CRISPR (Acr) proteins are natural inhibitors of clustered regularly interspaced short palindromic repeat (CRISPR)–CRISPR-associated protein (Cas) systems, providing valuable tools for regulating genome editing. Here, we present the crystal structure

The size of the immune repertoire of bacteria

, 2019
Some bacteria and archaea possess an immune system, based on the CRISPR-Cas mechanism, that confers adaptive immunity against phage. In such species, individual bacteria maintain a "cassette" of viral DNA elements called spacers as a memory of past ...

Repurposing CRISPR-Cas13 systems for robust mRNA trans-splicing

Nature Communications
Type VI CRISPR enzymes have been developed as programmable RNA-guided Cas proteins for eukaryotic RNA editing. Notably, Cas13 has been utilized for site-targeted single base edits, demethylation, RNA cleavage or knockdown and alternative splicing ...

CRISPR/Cas as a tool to overcome drug resistance in cancer: From challenge to opportunity

Molecular and Cellular Probes
Drug resistance remains a significant challenge in cancer therapy, often resulting in treatment failure, tumor progression, and metastasis. The underlying resistance mechanisms—including genetic mutations, epigenetic alterations, and modifications in ...
