CRISPR News and Research

In the late 1980s and mid-1990s, genomes of diverse lineages of bacteria and archaea (the latter representing a domain of single-celled prokaryotic microorganisms) revealed clusters of regularly interspaced short palindromic repeats, known today under the abbreviation CRISPR. Later it was found that these repeat sequences (previously considered disparate) share a common set of features.

New technique increases the precision of gene editing

A group of biomolecular engineers from Rice University has now identified a C-worthy method that significantly improves the precision of gene editing.

Golgi membrane protein drives growth and invasion of breast cancer

The cover for issue 28 of Oncotarget features Figure 5, "TMEM165 expression levels alters N-linked glycosylation," by Murali, et al., and reported that the TMEM165 protein was not detected in non-malignant matched breast tissues and was detected in invasive ductal breast carcinoma tissues by mass spectrometry.

Scientists develop new genome editing methods for better crop yield

Although crop hybrid technologies have played a key role in considerably improving crop yield across the world in the past decades, developing and maintaining a hybrid production line has invariably been laborious and complex.

Study may provide a therapeutically safer strategy for gene editing

The CRISPR gene editing system is a robust tool specifically developed for the targeted editing of genomes. While this tool has considerable therapeutic potential, it is associated with improper editing of “off-target” sites.

Single-nucleus RNA sequencing helps compare transcriptional responses to acute cocaine

The lab of Jeremy Day, Ph.D., at the University of Alabama at Birmingham, has used single-nucleus RNA sequencing approaches to compare transcriptional responses to acute cocaine in 16 unique cell populations from a portion of the brain called the nucleus accumbens, or NAc.

New type of molecular editor can make precise changes in mitochondrial DNA

The genome in mitochondria -- the cell's energy-producing organelles -- is involved in disease and key biological functions, and the ability to precisely alter this DNA would allow scientists to learn more about the effects of these genes and mutations.

Salk researchers discover genetic 'dial' to fine-tune the immune response

The human immune system is a finely-tuned machine, balancing when to release a cellular army to deal with pathogens, with when to rein in that army, stopping an onslaught from attacking the body itself.

Researchers discover protein involved in protecting B cells

Whenever a germ gets into the human body, the immune system usually responds immediately to fight off the enemy attacker. One of our defense system's most important strategies involves B lymphocytes, also known as B cells, which produce antibodies that target and neutralize pathogens.

Scientists develop CRISPR-assisted method to detect RNA-binding proteins in living cells

While scientists still don't fully understand the diverse nature of RNA molecules, it is believed that the proteins binding to them, called RNA-binding proteins, are associated with many disease formation.

Researchers develop a series of APOBEC-Cas9 fusion-induced deletion systems

Many small regulatory elements, including miRNAs, miRNA binding sites, and cis-acting elements, comprise only 5~24 nucleotides and play important roles in regulating gene expression, transcription and translation, and protein structure, and thus are promising targets for gene function studies and crop improvement.

Deep-learning-based computational models predict the activities of SpCas9 variants

Specific sequences of DNA are typically cut using CRISPR-Cas9 that has become one of the most effective and convenient biotechnology tools today.

New system of gene editing allows for targeted, super-fast DNA repair

In a series of experiments using human cancer cell lines, scientists at Johns Hopkins Medicine say they have successfully used light as a trigger to make precise cuts in genomic material rapidly, using a molecular scalpel known as CRISPR, and observe how specialized cell proteins repair the exact spot where the gene was cut.
