OAS1: The Cost of Host Defense

OAS1 The Cost of Host Defense
OAS1 (Oligoadenylate synthetase 1) is induced by type 1 interferon signaling. It recognizes 18 bp (or longer) double stranded RNA segments from invading viruses in the cytosol and catalyzes the production of 2’-5’ linked oligoadenylate (2-5A) from ATP. The 2-5A then, at the expense of yet more ATP, exclusively activates endoribonclease L (RNase L) by

Exploring the Use of NUDT5 Inhibitors to Treat Breast Cancer

malignant adenocarcinoma could be treated by NUDT5 Inhibitors
NUDT5 is found to be overexpressed in certain cancers in humans Could NUDT5 inhibitors lead to new cancer treatments? NUDIX hydrolases are a superfamily of enzymes are found in all classes of organisms and are responsible for hydrolyzing modified nucleoside diphosphates. One of the most well-studied NUDIX hydrolases is NUDT1 (also known as MTH1); it

JAK3 Inhibitors in the Treatment of Autoimmune Disease

JAK3 Inhibitors In the Fight Against Autoimmune Disease
Autoimmune disorders such as multiple sclerosis, psoriasis, and rheumatoid arthritis (RA), just to name a few, affect millions of people and have various contributing factors that lead to disease; some known and some unknown.   These disorders occur due to the immune system’s failure to discriminate between self vs. foreign entities. Janus Kinase 3 (JAK3) is

A Kinase Assay Kit to Interrogate Innate Immunity Targets

Performing a Kinase Assay Kit in a Lab
Kinases are essential players in cellular functions such as cell signaling, cellular transport, and protein regulation. For these reasons, many kinases are innate immunity targets. A kinase assay kit is ideal whether used for drug screening and dose-response measurements or detection when studying a particular cellular pathway. A universal ADP assay allows researchers to screen

New TR-FRET Readout Now Available with the Transcreener cGAMP cGAS Assay

New cGAS TR-FRET Assay
Launched in November 2019, the Transcreener cGAMP cGAS Assay has generated a great deal of interest in the drug discovery community. While fluorescence polarization (FP) readouts offer a stable and robust option, some researchers prefer time-resolved Förster-resonance-energy-transfer (TR-FRET) readouts for large screens. After months of development, BellBrook Labs is pleased to announce the addition of

FUT7, Inflammation, and Fucosyltransferase Assays

FUT7 Fucosyltransferase Assays and Chronic Inflammation
Inflammation is a necessary step involved in the immune response, allowing our bodies to fight and eliminate disease, allergies, and injuries. The inflammatory response recruits several mediators to aid in the destruction of whatever pathogen caused the response in the first place. Cells such as leucocytes, eosinophils, and neutrophils get recruited to the site in
