Differing from the traditional view that power frequency electric field is always considered a negative phenomenon, here we report concept uses directly as an energy source to generate sensing signals. To demonstrate this, integrated bionic perception and transmission nerve device (BPTND) based on developed. The BPTND can effectively simulate sensory nervous systems by integrating perception, recognition, functions detect transmit positional information of mechanical stimulation. Results...

Although many genes have been implicated in the pathogenesis of common neurodegenerative diseases, genetic and cellular mechanisms that maintain neuronal integrity during normal aging remain elusive. Here we show Caenorhabditis elegans touch receptor cholinergic neurons display age-dependent morphological defects, including cytoskeletal disorganization, axon beading, defasciculation. Progression is regulated by DAF-2 DAF-16 signaling, which also modulate adult life span. Mutations disrupt...

Significance In this study, we identify nerve-released glial cell line-derived neurotrophic factor (GDNF) family receptor (GFR)α1 as a key that enhances perineural invasion (PNI) through GDNF-Ret proto-oncogene (RET) signaling. We demonstrate GFRα1 is released from nerves in soluble form and cooperates with secreted GDNF to activate cancer surface RET, activating downstream signaling, migration, PNI. These findings advance our understanding of the molecular mechanisms PNI define specific...

Abstract Perineural invasion (PNI) is an ominous event strongly linked to poor clinical outcome. Cells residing within peripheral nerves collaborate with cancer cells enable PNI, but the contributing conditions tumor microenvironment are not well understood. Here, we show that CCR2-expressing inflammatory monocytes (IM) preferentially recruited sites of where they differentiate into macrophages and potentiate nerve through a cathepsin B–mediated process. A series adoptive transfer...

Anaplastic thyroid carcinoma (ATC) is a fatal disease with median survival of only 6 months. Novel therapies are needed to improve dismal outcomes.A mutated, replication-competent, vaccinia virus (GLV-1h68) has oncolytic effects on human ATC cell lines in vitro. We assessed the utility GLV-1h68 treating anaplastic cancer vivo.Athymic nude mice xenograft flank tumors ATCs (8505C and DRO90-1) were treated single intratumoral injection at low dose (5x10(5) plaque-forming unit), high (5x10(6) or...

Background: Diabetes is known to impair wound healing and deteriorate the periodontal condition. There limited information about patterns events associated with repair. In this study, we evaluate dynamics of repair using micro‐computed tomography (microCT) immunohistochemistry. Methods: Thirty‐six male rats were used, diabetes was induced by streptozotocin.

Significance Structural remodeling of neurons after insults to the nervous system includes retraction dysfunctional synaptic branches and growth primary neurites or new collateral branches. We find that genetic disruption neuronal microtubules in Caenorhabditis elegans triggered structural through RHGF-1/RhoGEF, which is normally associated with inhibited by microtubules. A conserved dual leucine zipper kinase, DLK-1, was activated RHGF-1-dependent signaling, DLK-1 transported from distal...

We investigated the therapeutic efficacy of a replication-competent oncolytic vaccinia virus, GLV-1h153, carrying human sodium iodide symporter (hNIS), in combination with radioiodine an orthotopic triple-negative breast cancer (TNBC) murine model. In vitro viral infection was confirmed by immunoblotting and uptake assays. Orthotopic xenografts (MDA-MB-231 cells) received intratumoral injection GLV-1h153 or PBS. One week after injection, were randomized into 4 treatment groups: alone, 131I...

Spatial arrangement of neurite branching is instructed by both attractive and repulsive cues. Here we show that in C. elegans, the Wnt family secreted glycoproteins specify sites PLM mechanosensory neurons. Wnts function through MIG-1/Frizzled planar cell polarity protein (PCP) VANG-1/Strabismus/Vangl2 to restrict formation F-actin patches, which mark nascent neurites.

Neuronal cargos are differentially targeted to either axons or dendrites, and this polarized cargo targeting critically depends on the interaction between microtubules molecular motors. From a forward mutagenesis screen, we identified gain-of-function mutation in C. elegans α-tubulin gene mec-12 that triggered synaptic vesicle mistargeting, neurite swelling neurodegeneration touch receptor neurons. This missense replaced an absolutely conserved glycine H12 helix with glutamic acid, resulting...
