Selective autophagy controls innate immune response through a TAK1/TAB2/SH3PX1 axis.
(CELL PRESS, 2022-01-25)
Selective autophagy is a catabolic route that turns over specific cellular material for degradation by lysosomes, and whose role in the regulation of innate immunity is largely unexplored. Here, we show that the apical ...
DRP1 levels determine the apoptotic threshold during embryonic differentiation through a mitophagy-dependent mechanism.
(CELL PRESS, 2022-06-06)
The changes that drive differentiation facilitate the emergence of abnormal cells that need to be removed before they contribute to further development or the germline. Consequently, in mice in the lead-up to gastrulation, ...
Estrogen receptor positive breast cancers have patient specific hormone sensitivities and rely on progesterone receptor.
(NATURE PORTFOLIO, 2022-06-06)
Estrogen and progesterone receptor (ER, PR) signaling control breast development and impinge on breast carcinogenesis. ER is an established driver of ER + disease but the role of the PR, itself an ER target gene, is debated. ...
ERG activity is regulated by endothelial FAK coupling with TRIM25/USP9x in vascular patterning.
(COMPANY BIOLOGISTS LTD, 2022-07-01)
Precise vascular patterning is crucial for normal growth and development. The ERG transcription factor drives Delta-like ligand 4 (DLL4)/Notch signalling and is thought to act as a pivotal regulator of endothelial cell ...
LKB1 is required for hepatic bile acid transport and canalicular membrane integrity in mice.
(2011-02)
LKB1 is a 'master' protein kinase implicated in the regulation of metabolism, cell proliferation, cell polarity and tumorigenesis. However, the long-term role of LKB1 in hepatic function is unknown. In the present study, ...
Actin-myosin-based contraction is responsible for apoptotic nuclear disintegration.
(2005-01)
Membrane blebbing during the apoptotic execution phase results from caspase-mediated cleavage and activation of ROCK I. Here, we show that ROCK activity, myosin light chain (MLC) phosphorylation, MLC ATPase activity, and ...
Integration of RNAi and Small Molecule Screens to Identify Targets for Drug Development.
(2019-01)
Cellular models for siRNA and small molecule high-throughput screening have been widely used in the last decade to identify targets for drug discovery. As an example, we present a twofold readout approach based on cell ...
Chemotaxis towards hyaluronan is dependent on CD44 expression and modulated by cell type variation in CD44-hyaluronan binding.
(COMPANY OF BIOLOGISTS LTD, 2005-11-01)
The accumulation of the extracellular matrix glycosaminoglycan hyaluronan by tumours and tumour-associated stroma promotes cancer cell invasion and metastasis. Using the Dunn chamber chemotaxis assay, we demonstrate for ...
Signalling pathways implicated in early mammary gland morphogenesis and breast cancer.
(PUBLIC LIBRARY SCIENCE, 2006-08-01)
Specification of mammary epithelial cell fate occurs during embryogenesis as cells aggregate to form the mammary anlage. Within the embryonic mammary bud, a population of epithelial cells exists that will subsequently ...
Cancer Burden Is Controlled by Mural Cell-β3-Integrin Regulated Crosstalk with Tumor Cells.
(CELL PRESS, 2020-06-11)
Enhanced blood vessel (BV) formation is thought to drive tumor growth through elevated nutrient delivery. However, this observation has overlooked potential roles for mural cells in directly affecting tumor growth independent ...
