Deubiquitylating enzymes (DUBs) as pharmaceutical targets
Â
While it is likely that all Ubiquitin-Like proteins (UBLs) will be important for drug discovery because of these associations, Ubiquitin has been the most completely validated for this purpose by genetic,
New findings in the TGF-beta pathway
Three papers on the role of the TGF-beta pathway in different cancers have recently been published.
It was already known that this pathway is involved in processes such as cell growth, cell differentiation,
A focus on the Wnt Pathway
The Wnt cell signalling pathway is a high-potential therapeutical target in cancer research. It's deeply linked to cellular fate through modulating cell proliferation, mobility, interaction, and polarity.
IQF substrates for true isopeptidase/deubiquitinase activity measurement
Deubiquitylating enzymes (DUBs) are promising therapeutical targets, especially in oncology (see my previous post dedicated to this topic). Today, I'd like to introduce you to new innovative
TUBEs: study M1 (linear) polyubiquitylated proteins
Traditional methods to detect and purify poly-ubiquitinated proteins require either anti-ubiquitin antibodies or Ubiquitin Binding Associated domains (UBAs). Most of the current methods display rather
ELISA test to confirm elimination of Host Cell Proteins (HCP) from bioproductions
Expression systems - removing their contaminants
CHO, E. Coli and Pichia are useful expression systems for drug production. This can be for proteins, enzymes or antibody productions. Research and development
Develop robust and convenient cell based assays with Gaussian Luciferase
Cell-based assays have become a classic way to monitor cells' reactions to a treatment or a specific stimulus. They involve a reporter construction and a detection system. The classic system is Firefly
Luciferase promoter reporter clones
Cell-based assays, screening for pathway activation or inhibition are classically done with promoter reporter clones expressing Firefly luciferase. Brighter, more stable, more sensitive, more convenient
shRNA set with improved performances
Optimal knock-down can be done by a shRNA sequence that depends on the gene expression level and the cell type. Usually, 4 shRNA should be tested to find the one inducing a minimum of 70% increase of the
VU-1: The most efficient monoclonal Antibody for ubiquitin detection
In the field of anti-ubiquitin antibodies many solutions are available on the market. But LifeSensors, a company specialized in Ubiquitin research field, have developped a monoclonal antibody called VU-1
ORF expressing Lentiviral system
ORF expression in Mammalian cells is very useful for many applications: protein production with HEK293, over-expression of tagged protein for immuno-tracking or immuno-precipitation, development of a cell
Gene knock-out in hard-to-transfect cells
Gene knock-out, which is gene editing leading to loss of function, just requires delivering into cells the 2 CRISPR system actors: the CAS9 endonuclease and the specific guide RNA to target the gene of
