Alternative catalytic residues in the active site of Esco acetyltransferases.
(NATURE PUBLISHING GROUP, 2020-06-17)
Cohesin is a protein complex whose core subunits, Smc1, Smc3, Scc1, and SA1/SA2 form a ring-like structure encircling the DNA. Cohesins play a key role in the expression, repair, and segregation of eukaryotic genomes. ...
Characterization of Hedgehog Acyltransferase Inhibitors Identifies a Small Molecule Probe for Hedgehog Signaling by Cancer Cells.
(AMER CHEMICAL SOC, 2016-12-16)
The Sonic Hedgehog (Shh) signaling pathway plays a critical role during embryonic development and cancer progression. N-terminal palmitoylation of Shh by Hedgehog acyltransferase (Hhat) is essential for efficient signaling, ...
Characterisation of CCT271850, a selective, oral and potent MPS1 inhibitor, used to directly measure in vivo MPS1 inhibition vs therapeutic efficacy.
(NATURE PUBLISHING GROUP, 2017-04-25)
BACKGROUND: The main role of the cell cycle is to enable error-free DNA replication, chromosome segregation and cytokinesis. One of the best characterised checkpoint pathways is the spindle assembly checkpoint, which ...
Myosin and Actin Filaments in Muscle: Structures and Interactions.
(SPRINGER INTERNATIONAL PUBLISHING AG, 2017-01-01)
In the last decade, improvements in electron microscopy and image processing have permitted significantly higher resolutions to be achieved (sometimes <1 nm) when studying isolated actin and myosin filaments. In the case ...
Structural rearrangements of the RNA polymerase III machinery during tRNA transcription initiation.
(ELSEVIER SCIENCE BV, 2018-04-01)
RNA polymerase III catalyses the synthesis of tRNAs in eukaryotic organisms. Through combined biochemical and structural characterisation, multiple auxiliary factors have been identified alongside RNA Polymerase III as ...
Genome-wide and high-density CRISPR-Cas9 screens identify point mutations in PARP1 causing PARP inhibitor resistance.
(NATURE PUBLISHING GROUP, 2018-05-01)
Although PARP inhibitors (PARPi) target homologous recombination defective tumours, drug resistance frequently emerges, often via poorly understood mechanisms. Here, using genome-wide and high-density CRISPR-Cas9 ...
MIR21 Drives Resistance to Heat Shock Protein 90 Inhibition in Cholangiocarcinoma.
(W B SAUNDERS CO-ELSEVIER INC, 2018-03-01)
BACKGROUND & AIMS: Cholangiocarcinomas (CCA) are resistant to chemotherapy, so new therapeutic agents are needed. We performed a screen to identify small-molecule compounds that are active against CCAs. Levels of microRNA ...
Patient-derived organoids model treatment response of metastatic gastrointestinal cancers.
(AMER ASSOC ADVANCEMENT SCIENCE, 2018-02-23)
Patient-derived organoids (PDOs) have recently emerged as robust preclinical models; however, their potential to predict clinical outcomes in patients has remained unclear. We report on a living biobank of PDOs from ...
Regulation of Wnt/β-catenin signalling by tankyrase-dependent poly(ADP-ribosyl)ation and scaffolding.
(WILEY, 2017-12-01)
UNLABELLED: The Wnt/β-catenin signalling pathway is pivotal for stem cell function and the control of cellular differentiation, both during embryonic development and tissue homeostasis in adults. Its activity is carefully ...
RET recognition of GDNF-GFRα1 ligand by a composite binding site promotes membrane-proximal self-association.
(CELL PRESS, 2014-09-25)
The RET receptor tyrosine kinase is essential to vertebrate development and implicated in multiple human diseases. RET binds a cell surface bipartite ligand comprising a GDNF family ligand and a GFRα coreceptor, resulting ...
