Published a day ago Submitted by CRB Decades of scientific progress in understanding the root cause of many formerly intractable diseases has opened up new treatment options, namely through RNA-based therapies. This second wave of biopharma, in which our understanding of the ways coding portions of our genome relate to…

PAM identification of NcCas9 by PAM-DOSE The type II-C Cas9 orthologue NcCas9 is of small size (1082 aa) and is closely related to conventional Neisseria meningitidis Cas9 (NmeCas9)11 (Fig. 1a). The NcCas9 is 94% identical to Nme1Cas9, and the divergences lie mainly in the C-terminal PAM-interacting domain (PID) (Fig. 1a and S1)….

The Patent Trial and Appeal Board (like its predecessor, the Board of Patent Appeals and Interferences or BPAI) occasionally renders an opinion having the tendency to raise an eyebrow or two, which on occasion has led the Federal Circuit, like its predecessor the Court of Claims and Patent Appeals, to…

Why is RNA important in immunity? All organisms, from single-celled bacteria to blue whales, have a genome that’s made of deoxyribonucleic acid, or DNA. When it comes to viruses, many use single-stranded ribonucleic acid (RNA). However, certain species (such as rotavirus, which causes gastroenteritis) have a double-stranded RNA genome. The…

Mice A laboratory strain B6 was purchased from CLEA Japan Inc. (Tokyo, Japan), while nine wild strains (BFM/2, BLG2, CHD, HMI, KJR, MSM, NJL, PGN2, and SWN) were bred at NIG (Shizuoka, Japan) (Table 1). All mice were maintained at the animal facility in NIG, under specific-pathogen-free conditions and controlled…

Researchers at the Korean Institute of Life Sciences and Technology engineered an efficient, miniaturized CRISPR-Cas gene-editing system that may be more easily packed into vectors for clinical applications. Their system employs the Cas variant Cas12f1 with a guide RNA (gRNA) remodeled to mitigate off-target effects, a design that could potentially…

RNA-guided CRISPR-Cas nucleases are widely used as versatile genome-engineering tools. Recent studies identified functionally divergent type V Cas12 family enzymes. Among them, Cas12c2 binds a CRISPR RNA (crRNA) and a trans-activating crRNA (tracrRNA) and recognizes double-stranded DNA targets with a short TN PAM … RNA-guided CRISPR-Cas nucleases are widely used…

1. Introduction The approval of Chinese hamster ovary (CHO) cell cultures for the manufacturing of protein therapeutic products modernized conventional medicine. CHO cells remained the workhorse for the production of monoclonal antibodies (mAbs) for the last at least 20 years for different reasons. First, CHO cells are easily adapting and…

In nature, microbes have evolved different systems to sense external stimuli. Synthetic biology approaches (1) repurpose these systems as biosensors to specifically and sensitively detect various targets of interest. Although various highly sensitive and specific laboratory-based analytical methods (including high-performance liquid chromatography and mass spectrometry) can detect small-molecule targets, they…

Introduction: The CRISPR-Cas system is a crucial defense system against foreign invaders, like bacteriophage, transposons, and plasmids in many prokaryotes….
