Live animal in vivo imaging is a common and useful tool for research, but current tools could be better. Two recent papers discuss adaptations of BRET technology combining the brightness of fluorescence with the low background of a bioluminescence reaction to create enhanced in vivo imaging capabilities. The key is to image photons at wavelengths above 600nm, as […]
Today’s blog is written by guest blogger Kristin Huwiler from our Cellular Analysis and Proteomics Group. Two research collaborations, one in Europe and a second in the US, have just published in Nature Chemical Biology (1,2) on the identification of BET inhibitors (bi-BETs) that bind via a bivalent mechanism to both bromodomains of BRD4. These bivalent […]
Robert Hooke first coined the term “cell” after observing plant cell walls through a light microscope—little empty chambers, fixed in time and space. However, cells are anything but fixed. Cells are dynamic: continually responding to a shifting context of time, environment, and signals from within and without. Interactions between the macromolecules within cells, including proteins, are […]
In 1982, picked up because of its homology to chicken virus genes that could transform cells, MYC became one of the first human genes identified that could drive cellular transformation (1,2). Since that time countless laboratories have prodded and poked the human MYC gene, the MYC protein, their homologs in other animal models, and their transforming […]
In a paper published in the September 2014 issue of ACS Medicinal Chemistry Letters, researchers from GlaxoSmithKline in the UK and Germany report on the discovery, binding mode and structure:activity relationship of a potent BRPF1 (bromodomain and PHD finger containing protein family) inhibitor. This paper came to our attention as it is one of the […]
The use of reporter genes for simple analysis of promoter activity (promoter bashing) is a well known practice. However, there are many other elegant applications of reporter technologies. One such application is illustrated in the paper by Zheng et al., published in the Sept. 2008 issue of Cancer Research. These researchers from the Hormel Institute […]
