Bioluminescence Resonance Energy Transfer 2 (BRET2)-Based RAS Biosensors to Characterize RAS Inhibitors.
(Wiley, 2019-06-01)
Protein-protein interactions (PPIs) are principle biological processes that control normal cell growth, differentiation, and homeostasis but are also crucial in diseases such as malignancy, neuropathy, and infection. Despite ...
BRET-based RAS biosensors that show a novel small molecule is an inhibitor of RAS-effector protein-protein interactions.
(ELIFE SCIENCES PUBLICATIONS LTD, 2018-07-10)
The RAS family of proteins is amongst the most highly mutated in human cancers and has so far eluded drug therapy. Currently, much effort is being made to discover mutant RAS inhibitors and in vitro screening for RAS-binding ...
Small molecule inhibitors of RAS-effector protein interactions derived using an intracellular antibody fragment.
(NATURE PORTFOLIO, 2018-08-09)
Targeting specific protein-protein interactions (PPIs) is an attractive concept for drug development, but hard to implement since intracellular antibodies do not penetrate cells and most small-molecule drugs are considered ...
Structural and functional characterization of a DARPin which inhibits Ras nucleotide exchange.
(NATURE PUBLISHING GROUP, 2017-07-14)
Ras mutations are the oncogenic drivers of many human cancers and yet there are still no approved Ras-targeted cancer therapies. Inhibition of Ras nucleotide exchange is a promising new approach but better understanding ...
KRAS-specific inhibition using a DARPin binding to a site in the allosteric lobe.
(NATURE PUBLISHING GROUP, 2019-06-13)
Inhibiting the RAS oncogenic protein has largely been through targeting the switch regions that interact with signalling effector proteins. Here, we report designed ankyrin repeat proteins (DARPins) macromolecules that ...
Lipid-mRNA Nanoparticle Designed to Enhance Intracellular Delivery Mediated by Shock Waves.
(AMER CHEMICAL SOC, 2019-03-20)
Cellular membranes are, in general, impermeable to macromolecules (herein referred to as macrodrugs, e.g., recombinant protein, expression plasmids, or mRNA), which is a major barrier for clinical translation of macrodrug-based ...
Cloning, purification and structure determination of the HIV integrase-binding domain of lens epithelium-derived growth factor.
(INT UNION CRYSTALLOGRAPHY, 2018-03-01)
Lens epithelium-derived growth factor (LEDGF)/p75 is the dominant binding partner of HIV-1 integrase in human cells. The crystal structure of the HIV integrase-binding domain (IBD) of LEDGF has been determined in the absence ...
A potent KRAS macromolecule degrader specifically targeting tumours with mutant KRAS.
(NATURE PUBLISHING GROUP, 2020-06-26)
Tumour-associated KRAS mutations are the most prevalent in the three RAS-family isoforms and involve many different amino-acids. Therefore, molecules able to interfere with mutant KRAS protein are potentially important for ...
Identification of a minority population of LMO2+ breast cancer cells that integrate into the vasculature and initiate metastasis.
(AMER ASSOC ADVANCEMENT SCIENCE, 2022-11-11)
Metastasis is responsible for most breast cancer-related deaths; however, identifying the cellular determinants of metastasis has remained challenging. Here, we identified a minority population of immature THY1+/VEGFA+ ...
A non-cell autonomous mouse model of CNS haemangioblastoma mediated by mutant KRAS.
(NATURE PORTFOLIO, 2017-03-21)
Haemangioblastoma is a rare malignancy of the CNS where vascular proliferation causes lesions due to endothelial propagation. We found that conditionally expressing mutant Kras, using Rag1-Cre, gave rise to CNS haemangioblastoma ...
