Targeting PML in triple negative breast cancer elicits growth suppression and senescence
(Nature, 2020-04)
Oncogene addiction postulates that the survival and growth of certain tumor cells is dependent upon the activity of one oncogene, despite their multiple genetic and epigenetic abnormalities. This phenomenon provides a ...
Multiplex SERS Detection of Metabolic Alterations in Tumor Extracellular Media
(Wiley, 2020-04)
The composition and intercellular interactions of tumor cells in the tissues dictate the biochemical and metabolic properties of the tumor microenvironment. The metabolic rewiring has a profound impact on the properties ...
An atlas of O-linked glycosylation on peptide hormones reveals diverse biological roles
(Nature, 2020-08-20)
Peptide hormones and neuropeptides encompass a large class of bioactive peptides that regulate physiological processes like anxiety, blood glucose, appetite, inflammation and blood pressure. Here, we execute a focused ...
Preformulation Studies of a Stable PTEN-PDZ Lipopeptide Able to Cross an In Vitro Blood-Brain-Barrier Model as a Potential Therapy for Alzheimer's Disease
(Springer, 2020-08-04)
PurposeAmyloid beta (A beta) drives the accumulation of excess Phosphatase and Tensin Homolog Deleted on Chromosome 10 (PTEN) at synapses, inducing synaptic depression and perturbing memory. This recruitment of PTEN to ...
Structural Characterization of the ICOS/ICOS-L Immune Complex Reveals High Molecular Mimicry by Therapeutic Antibodies
(Nature, 2020-10-08)
The inducible co-stimulator (ICOS) is a member of the CD28/B7 superfamily, and delivers a positive co-stimulatory signal to activated T cells upon binding to its ligand (ICOS-L). Dysregulation of this pathway has been ...
Unveiling the activation dynamics of a fold-switch bacterial glycosyltransferase by 19F NMR
(American Society for Biochemistry and Molecular Biology, 2020-07-17)
Fold-switch pathways remodel the secondary structure topology of proteins in response to the cellular environment. It is a major challenge to understand the dynamics of these folding processes. Here, we conducted an in-depth ...
Microfluidic chip with pillar arrays for controlled production and observation of lipid membrane nanotubes
(Royal Society of Chemistry, 2020-08-07)
Lipid membrane nanotubes (NTs) are a widespread template forin vitrostudies of cellular processes happening at high membrane curvature. Traditionally NTs are manufactured one by one, using sophisticated membrane ...
A fluorogenic cyclic peptide for imaging and quantification of drug-induced apoptosis
(Nature, 2020-08-12)
Programmed cell death or apoptosis is a central biological process that is dysregulated in many diseases, including inflammatory conditions and cancer. The detection and quantification of apoptotic cells in vivo is hampered ...
The Golgi as an Assembly Line to the Autophagosome
(Elsevier, 2020-06)
Autophagy is traditionally depicted as a signaling cascade that culminates in the formation of an autophagosome that degrades cellular cargo. However, recent studies have identified myriad pathways and cellular organelles ...
Photoacoustic effect applied on model membranes and living cells: direct observation with multiphoton excitation microscopy and long-term viability analysis
(Nature, 2020-01-15)
The photoacoustic effect is generated when a variable light interacts with a strongly light-absorbing material. In water, it may produce hot bubbles and shock waves that could affect the integrity of nearby cellular ...
