The dynamin inhibitor, dynasore, prevents zoledronate-induced viability loss in human gingival fibroblasts by partially blocking zoledronate uptake and inhibiting endosomal acidification [PDF]

Journal of Applied Oral Science
Objective For treatment of medication-related osteonecrosis of the jaw, one proposed approach is the use of a topical agent to block entry of these medications in oral soft tissues.

REST-Governed Gene Expression Profiling in a Neuronal Cell Model Reveals Novel Direct and Indirect Processes of Repression and Up-Regulation [PDF]

, 2015
The role of REST changes in neurons, including the rapid decrease of its level during differentiation and its fluctuations during many mature functions and diseases, is well established. However, identification of many thousand possible REST-target genes,

Membrane curvature controls dynamin polymerization [PDF]

Proceedings of the National Academy of Sciences, 2010
The generation of membrane curvature in intracellular traffic involves many proteins that can curve lipid bilayers. Among these, dynamin-like proteins were shown to deform membranes into tubules, and thus far are the only proteins known to mechanically drive membrane fission.

CD28‐Targeted Enzyme‐Responsive Conformation‐Switching Peptide Self‐Assembly for Selective T‐Cell Acute Lymphoblastic Leukemia (T‐ALL) Therapy

Advanced Science, EarlyView.
We developed the enzyme‐responsive peptide SAp‐CD28 to selectively target CD28‐overexpressing T‐ALL cells. Following phosphatase‐mediated activation, SAp‐CD28 undergoes conformational switching and nanooligomerization, resulting in the disruption of CD28 downstream signaling.

Dynasore - not just a dynamin inhibitor [PDF]

, 2015
Dynamin is a GTPase protein that is essential for membrane fission during clathrin-mediated endocytosis in eukaryotic cells. Dynasore is a GTPase inhibitor that rapidly and reversibly inhibits dynamin activity, which prevents endocytosis.

Piezo1 Channel Mediates Mechanically Programmable Drug Delivery to Potentiate Intravesical Chemotherapy

Advanced Science, EarlyView.
This study utilizes programmable mechanical pressure as a therapeutic enhancer to establish a mechano‐chemotherapy strategy. Controlled pressure activates the mechanosensitive ion channel Piezo1 in bladder cancer, triggering a calcium ion cascade that transiently and reversibly amplifies membrane permeability to chemotherapeutics.

Physiological impact and disease reversion for the severe form of centronuclear myopathy linked to dynamin

JCI Insight, 2020
Classical dynamins are large GTPases regulating membrane and cytoskeleton dynamics, and they are linked to different pathological conditions ranging from neuromuscular diseases to encephalopathy and cancer.

Mitochondrial Enzymes Mimetic Ultrasmall Palladium Nanozymes Prevent Senescence and Neurodegeneration Through Metabolic Reprogramming

Advanced Science, EarlyView.
Simply constructed polyvinylpyrrolidone (PVP) modified palladium nanoparticles (PdP NPs) as cytochrome c oxidase (CcO) and superoxide dismutase (SOD) mimic are promising multifunctional nanoreactors to boost mitochondrial respiration chain function and refine homeostasis via regulation of mitochondrial dynamics and proteostasis sensor UPRmt, which ...

Endocytosis contributes to BMP2-induced Smad signalling and neuronal growth [PDF]

, 2017
Bone morphogenetic protein 2 (BMP2) is a neurotrophic factor which induces the growth of midbrain dopaminergic (DA) neurons in vitro and in vivo, and its neurotrophic effects have been shown to be dependent on activation of BMP receptors (BMPRs) and Smad

Adversarial Erasing Enhanced Multiple Instance Learning (siMILe): Discriminative Identification of Oligomeric Protein Structures in Single Molecule Localization Microscopy

Advanced Intelligent Systems, EarlyView.
Hallgrimson et al. introduce a machine learning algorithm, siMILe, that takes features of single‐molecule localization microscopy localization clusters (e.g., size and sphericity) and finds the clusters that are associated with certain cell conditions (such as differential protein expression or drug treatment).
