Hyperactivation of HER2-SHCBP1-PLK1 axis promotes tumor cell mitosis and impairs trastuzumab sensitivity to gastric cancer 2021 in vivo System
Title
Hyperactivation of HER2-SHCBP1-PLK1 axis promotes tumor cell mitosis and impairs trastuzumab sensitivity to gastric cancer
Description
Trastuzumab is the main component of HER2-directed gastric cancer therapy, but patient response is poor due to insufficient cell sensitivity and drug resistance. In this paper, the researchers report that HER2 is involved in cell mitotic promotion for tumorigenesis and a poor response of patients to trastuzumab therapy by hyperactivating a crucial HER2-SHCBP1-PLK1 axis. Theaflavine-3, 3’-digallate (TFBG), an inhibitor of the SHCBP1-PLK1 interaction, acts as a potential trastuzumab sensitizer and shows high efficacy in inhibiting the growth of HER2-positive gastric cancer when combined with trastuzumab. The longitudinal response of NCI-N87 tumor to trastuzumab is observed by in vivo luminescence imaging with Visque InVivo Smart-LF after the treatment of trastuzumab with knockdown of SHCBP1 or TFBG treatment on NCI-N87/luc tumor xenograft model mice.

Lung-selective 25-hydroxycholesterol nanotherapeutics as a suppressor of COVID-19-associated cytokine storm 2021 in vivo System
Title
Lung-selective 25-hydroxycholesterol nanotherapeutics as a suppressor of COVID-19-associated cytokine storm
Description
Decreased 25-hydroxycholesterol (25-HC) and increased cytokine levels is believed to play a crucial role in COVID-19 pathogenesis, inducing acute respiratory distress syndrome (ARDS) and sepsis. In this paper, the researchers develop 25-HC and didodecyldimethylammonium bromide (DDAB) nanovesicles (25-HC@DDAB) as a COVID-19 drug candidate for the restoration of intracellular cholesterol level and suppression of cytokine storm in severe SARS-CoV-2 patients. 25-HC@DDAB can selectively accumulate the lung tissues and effectively reduce inflammatory cytokine levels in COVID-19 patient-derived PBMCs. The researchers confirm the accumulation of 25-HC@DDAB in lung by ex vivo fluorescence imaging with Visque InVivo Smart at the specific time point after intravenous injection of 25-HC@DDAB into the tail vein of mice.

RNA interference-mediated suppression of TNF-α converting enzyme as an alternative anti-TNF-α therapy for rheumatoid arthritis 2021 in vivo System
Title
RNA interference-mediated suppression of TNF-α converting enzyme as an alternative anti-TNF-α therapy for rheumatoid arthritis
Description
For approximately 90% of patients with RA, anti-TNF-α therapy is treated as the first-line immuno-treatment since excessive tumor necrosis factor-α (TNF-α) is associated with the pathogenesis of rheumatoid arthritis (RA). In this paper, researchers suggested suppression of TNF-α converting enzyme (TACE) as a novel strategy to down-regulate TNF-α level. They developed a disease site-targeted RNA interference system by forming non-viral complex between shRNA against TACE (shTACE) and bone resorption site-specific peptide carrier. In collagen induced arthritis (CIA) model experiments, the shTACE/peptide carrier complex alleviated arthritic symptoms with enhanced anti-inflammatory and anti-osteoclastogenic effects. And, similar results were obtained with human origin cell experiments from tissues and synovial fluids of RA patients. The biodistribution of shTACE/peptide carrier complex was identified by in vivo fluorescence imaging with Visque InVivo Smart after intravenous injection of shTACE/peptide carrier complex into CIA model mice.

Dissecting the impact of target-binding kinetics of protein binders on tumor localization 2021 in vivo System
Title
Dissecting the impact of target-binding kinetics of protein binders on tumor localization
Description
To improve the therapeutic effects of protein-based therapeutics, their in vivo behavior is considered and controlled systematically. In this paper, the researchers investigate the influence of the binding affinity of proteins on tumor localization by using four repebodies having different affinities to EGFR on cancer model mice. They find that optimal affinity with balanced target binding and dissociation can facilitate deep penetration and accumulation of protein binders in tumors by overcoming the binding-site-barrier effect. The BioDistribution of repebodies in the body is identified and quantitated by in vivo fluorescence imaging with Visque InVivo Smart-LF at specific time points after the intravenous injection of various repebody into A431 tumor xenograft model mice.

Title
Neutrophil-like Cell-Membrane-Coated Nanozyme Therapy for Ischemic Brain Damage and Long-Term Neurological Functional Recovery
Description
In this paper, the researchers suggest a noninvasive active-targeting therapy for ischemic stroke using a neutrophil-like cell-membrane-coated mesoporous Prussian blue nanozyme (MPBzyme@NCM). Despite its robust anti-inflammatory and antioxidative stress properties, nanozyme has shown unsatisfactory therapeutic effects due to its insufficient accumulation in the ischemic brain via noninvasive administration. The researchers improve its delivery to the lesion site by coating the nanozyme with the neutrophil-like membrane. They also demonstrate the long-term in vivo therapeutic efficacy for ischemic stroke after the delivery into the damaged brain. The in vivo fluorescence imaging with Visque InVivo Elite is used to confirm the accumulation of MPBzyme@NCM at the lesion site over time.

Interrogation of Folic Acid-Functionalized Nanomedicines: The Regulatory Roles of Plasma Proteins Reexamined
Description
Folic acid (FA) has been widely used to promote targeted delivery of nanomedicines to tumors since the folate receptor-α (FR-α) is overexpressed in many human cancers. In this paper, the researchers find that the FA functionalization induces heavy natural IgM absorption on the liposomal surface, preventing FA from binding receptors and accelerating complement activation in vivo. In addition, FA-functionalized polymeric nanoparticles are found to be vulnerable to natural IgM absorption. The biodistribution of FA-functionalized liposome (FA-sLip) at specific time points after the tail vein is observed using in vivo fluorescence imaging with Visque InVivo Elite.

Title
Supramolecular Container-Mediated Surface Engineering Approach for Regulating the Biological Targeting Effect of Nanoparticles
Description
In this paper, researchers suggest a supramolecular container-based surface engineering approach to make a chemical bridge to incorporate nanoparticles and targeting ligands. The researchers use an acyclic cucurbituril (aCB) molecular container as a supramolecular container to incorporate nanoparticles and targeting ligands via a bilateral host-guest complexation, enabling better water dispersibility and enhanced biological targeting. The aCB-engineered nanoparticles show the enhanced biological targeting effect and targeted imaging performance in in vitro and in vivo experiments. The enhanced targeting and imaging performance are demonstrated by the fluorescence imaging of tumor-bearing mice with Visque InVivo Elite at the specific time point after intravenous injection of rhodamine B isothiocyanate (RITC)-labeled nanoparticle.

Title
Enhancement of Nanozyme Permeation by Endovascular Interventional Treatment to Prevent Vascular Restenosis via Macrophage Polarization Modulation
Description
In this paper, the researchers examine nanozymes as an effective therapeutic strategy for vascular restenosis after endovascular interventional treatment. Nanozymes are excellent at scavenging ROS, the major aggravating factor for vascular restenosis, but cannot efficiently pass through the vascular endothelial cell barrier to reach the vascular intima. The researchers discover that the endothelial cells exfoliation by endovascular interventional treatment enhances nanoparticle permeation into the vascular intima and uptake by macrophages to alleviate long-term vascular restenosis in vivo. The vascular restenosis is relieved after vascular balloon injury (VBI) under the presence of Prussian blue nanozyme (PBzyme). The accumulation of PBzyme in left common carotid arteries of mice is confirmed with in vivo fluorescence imaging using Visque InVivo Elite.

Title
A molecular approach to rationally constructing specific fluorogenic substrates for the detection of acetylcholinesterase activity in live cells, mice brains and tissues
Description
In this paper, the researchers develop a specific substrate for Acetylcholinesterase (AChE) detection by combining dimethylcarbamate choline with a self-immolative scaffold. Imaging the activity of AChE which is tightly associated with neurological diseases is difficult due to the interference from butyrylcholinesterase (BChE) and carboxylesterase (CE). The representative substrate P10 can effectively eliminate the interference from CE and BChE. Its high specificity is confirmed via imaging AChE activity in vitro. Also, the AChE activity in a normal mouse brain is successfully captured via in vivo and ex vivo fluorescence imaging with Visque InVivo Elite.

Aminoacyl-tRNA synthetase complex-interacting multifunctional protein 1 (AIMP1)-derived peptide (AdP) has been developed as a cosmeceutical ingredient for skin anti-aging given its fibroblast-activating (FA) and melanocyte-inhibiting (MI) functions. However, a suitable strategy for the topical delivery of AdP was required due to its low-permeable properties. In this paper, the researcher developed hydrosol-based topical delivery system for AdP fragments which have effects on fibroblast and melanocyte. The optimized hydrosol showed 127-fold higher peptide deposition in STM than free FA-AdP. The quantification of the fluorescent dye-tagged FA-AdP in Strat-M membrane (STM) was carried out by near-infrared fluorescence imaging with Visque InVivo Smart.

Smart Microcapsules with Molecular Polarity- and Temperature-Dependent Permeability 2019 in vivo System
Title
Smart Microcapsules with Molecular Polarity- and Temperature-Dependent Permeability
Description
Microcapsules with molecule-selective permeation are appealing as microreactors, capsule-type sensors, drug and cell carriers, and artificial cells. In this paper, the researcher made water-in-oil-in-water (W/O/W) double-emulsion drops from two monomers and dodecanol with capillary microfluidic devices. The oil shell has selective permeability above melting point of dedecanol, which is drastically lowered below the melting point. The release from the oil shell was tested by in vivo fluorescence imaging with Visque InVivo Smart at specific time points after the subcutaneous injection of the ICG-loaded oil shell into the thigh of mice.

Oral Delivery of Honokiol Microparticles for Nonrapid Eye Movement Sleep 2019 in vivo System
Title
Oral Delivery of Honokiol Microparticles for Nonrapid Eye Movement Sleep
Description
Honokiol (HNK) is a small-molecule lignin extracted from Magnolia Officinalis, promoting nonrapid eye movement (NREM) sleep. However, the treatment of insomnia using HNK is restricted by its extremely low oral bioavailability. In this paper, the researcher made honokiol microparticle by loading honokiol into poly lactide-glycolide acid microparticles (HNK-MP). HNK-MP showed enhanced oral bioavailability, resulting in increased AUC0-12h and maximum blood concentration (Cmax), finally increased NREM sleep after oral administration in in vivo experiment. The researcher tested the biosafety of HNK-MP in vivo, and confirmed no damage in the gastrointestinal tract. The retention in the gastrointestinal tract was identified by ex vivo fluorescence imaging of the gastrointestinal tract with Visque InVivo Elite, after oral administration of HNK-MP to rats.

Title
Biodegradable Mesoporous Silica Achieved via Carbon Nanodots-Incorporated Framework Swelling for Debris-Mediated Photothermal Synergistic Immunotherapy
Description
The uniformly incorporating polymer-coated carbon nanodots (CDs) into ordered framework of mesoporous silica nanoparticles (CD@MSNs) was developed both for the photothermal therapy (PTT) and immunotherapy of cancer. The obtained CD@MSN showed enhanced photothermal effect and elevated targeting accumulation in vitro and in vivo. And CD@MSN-mediated PTT also showed immune-mediated inhibition of tumor metastasis by natural killer cells and macrophages. They observed biodistribution of CD@MSN by fluorescence imaging of isolated organs with Visque InVivo Smart at specific time points after injection into the body of mice.

Title
Osteogenesis and angiogenesis are simultaneously enhanced in BMP2-/VEGF-transfected adipose stem cells through activation of the YAP/TAZ signaling pathway.
Description
The osteogenic and angiogenic effect of BMP2-/VEGF-transfected adipose stem cells are simultaneously enhanced in critical-size calvarial defects and long-bone segmental defects in immunosuppressed rats. They identified with Visque InVivo Elite that the implanted stem cells did not migrate out of the implantation site by the 56th day. They suggest the possibility of using gene–cell therapy that can induce rapid angiogenesis and osteogenesis in inhospitable avascular environments.
