Reduced malignant glioblastoma recurrence post-resection through the anti-CD47 antibody and Temozolomide co-embedded in-situ hydrogel system.

Infiltrative glioma growth makes surgical excision incomplete, and the residual tumor cells proliferate rapidly. Residual glioma cells evade phagocytosis by macrophages through upregulating anti-phagocytosis molecule CD47, which binds to the signal regulatory protein alpha (SIRPα) of macrophages. Specifically, blocking the CD47-SIRPα pathway is a potential strategy for post-resection glioma treatment.

Downregulation of miR-192 Alleviates Oxidative Stress-Induced Porcine Granulosa Cell Injury by Directly Targeting Acvr2a.

Follicular atresia is primarily caused by breakdown to granulosa cells (GCs) due to oxidative stress (OS). MicroRNAs (miRNAs) elicit a defense response against environmental stresses, such as OS, by acting as gene-expression regulators. However, the association between miRNA expression and OS in porcine GCs (PGCs) is unclear.

Multifunctional Hybrid Hydrogel System Enhanced the Therapeutic Efficacy of Treatments for Postoperative Glioma.

Glioma is the most lethal brain tumor with a poor prognosis, and a combination of multiple therapeutic strategies is critical for postoperative glioma treatment. Herein, a multifunctional hybrid hydrogel system (designated as CP&CL@RNP-Gel) was developed for local treatment of postoperative glioma. The system was composed of self-illuminating chlorin e6 (Ce6) conjugated with luminol molecule (CL)-loaded glioma-targeting paclitaxel prodrug nanoparticles and copper peroxide nanodots (CP NDs) coembedded into a three-dimensional thermosensitive hydroxypropyl chitin hydrogel frame.

Advances of nano drug delivery system for the theranostics of ischemic stroke.

From the global perspective, stroke refers to a highly common cause of disability and death. Ischemic stroke (IS), attributed to blood vessel blockage, preventing the flow of blood to brain, acts as the most common form of stroke. Thus far, thrombolytic therapy is the only clinical treatment for IS with the approval from the FDA.

Enhanced treatment of cerebral ischemia-Reperfusion injury by intelligent nanocarriers through the regulation of neurovascular units.

Reperfusion injury is one of the major causes of disability and death caused by ischemic stroke, and drug development focuses mainly on single neuron protection. However, different kinds of cells in the neurovascular units (NVUs), including neurons, microglia and vascular endothelial cells, are pathologically changed after cerebral ischemia-reperfusion injury, resulting in an urgent need to develop a drug delivery system to comprehensively protect the kinds of cells involved in the NVU. Herein, we have constructed a c(RGDyK) peptide modified, NF-κB inhibitor caffeic acid phenethyl ester (CAPE)-loaded and reactive nitrogen species (RNS) stimuli-responsive liposomal nanocarrier (R-Lipo-CAPE) to target ischemic lesions and then remodel the NVU to reduce the progression of cerebral ischemia-reperfusion injury.

In situ targeting nanoparticles-hydrogel hybrid system for combined chemo-immunotherapy of glioma.

It is well known that glioma is currently the most malignant brain tumor. Because of the existence of blood-brain barrier (BBB) and tumor cell heterogeneity, systemic chemotherapy exerts unsatisfied therapeutic effect for the treatment of glioma after surgical resection and may even damage the body's immune system. Here, we developed an in situ sustained-release hydrogel delivery system for combined chemo-immunotherapy of glioma by combined chemotherapy drug and immunoadjuvant through the resection cavity local delivery.

HDAC6 Is Involved in the Histone Deacetylation of In Vitro Maturation Oocytes and the Reprogramming of Nuclear Transplantation in Pig.

It remained unknown whether HDAC6 affected the histone deacetylation of in vitro maturation oocytes and the reprogramming of nuclear transplantation in pig. Our results indicated that HDAC6 specific inhibition did not affect overall HDAC activity and meiosis process, which increased histone H3K9/K14 and H4K8 acetylation of porcine in vitro maturation oocytes and pseudo-pronucleus embryos. HDAC6 inhibition also significantly enhanced the cleavage and blastocyst of nuclear transfer embryos (0.

Background: There are few clinical challenges associated with the treatment of colorectal cancer (CRC). Studies have shown that TGF-β plays a crucial role in CRC. Importantly, celastrol, a major components of the root extract of the traditional Chinese herb , has been shown to inhibit the growth, adhesion, and metastasis of human CRC cells through the inhibition of TGF-β1/Smad signaling.

Glioma and microenvironment dual targeted nanocarrier for improved antiglioblastoma efficacy.

Drug delivery systems based on nanoparticles (nano-DDS) have aroused attentions for the treatment of glioblastoma (GBM), the most malignant brain cancer with a dismal prognosis. However, there are still numerous unmet challenges for traditional nano-DDS, such as the poor nanoparticle penetration, short retention in the GBM parenchyma and low glioma targeting ability. Herein, we used Pep-1 and CREKA peptides to construct a novel multifunctional GBM targeting nano-DDS (PC-NP).

Enhanced Antiglioblastoma Efficacy of Neovasculature and Glioma Cells Dual Targeted Nanoparticles.

Combining treatment of anticancer cells and antiangiogenesis is considered to be a potential targeted strategy for brain glioblastoma therapy. In this study, by utilizing the overexpression of Interleukin 13 receptor α2 (IL-13Rα2) on the glioma cells and heparan sulfate on neovascular endothelial cells, we developed a paclitaxel (PTX) loaded Pep-1 and CGKRK peptide-modified PEG-PLGA nanoparticle (PC-NP-PTX) for glioma cells and neovasculature dual-targeted chemotherapy to enhance the antiglioma efficacy. There were significant differences both on the enhancement of cellular uptake in HUVEC and C6 cells and on the improvement of in vitro antiglioma activity in the respect of proliferation, tumor spheroid growth, tube formation, and migration between PC-NP-PTX and Taxol and NP-PTX.

PEGylated Polyamidoamine dendrimer conjugated with tumor homing peptide as a potential targeted delivery system for glioma.

Glioblastoma multiforme (GBM) is the most common and aggressive primary central nervous system (CNS) tumor with a short survival time. The failure of chemotherapy is ascribed to the low transport of chemotherapeutics across the Blood Brain Tumor Barrier (BBTB) and poor penetration into tumor tissue. In order to overcome the two barriers, small nanoparticles with active targeted capability are urgently needed for GBM drug delivery.

Dual targeted nanocarrier for brain ischemic stroke treatment.

Focal cerebral ischemia, known as stroke, causes serious long-term disabilities globally. Effective therapy for cerebral ischemia demands a carrier that can penetrate the blood-brain barrier (BBB) and subsequently target the ischemia area in brain. Here, we designed a novel neuroprotectant (ZL006) loaded dual targeted nanocarrier based on liposome (T7&SHp-P-LPs/ZL006) conjugated with T7 peptide (T7) and stroke homing peptide (SHp) for penetrating BBB and targeting ischemia area, respectively.

Improved anti-glioblastoma efficacy by IL-13Rα2 mediated copolymer nanoparticles loaded with paclitaxel.

Glioma presents one of the most malignant brain tumors, and the therapeutic effect is often limited due to the existence of brain tumor barrier. Based on interleukin-13 receptor α2 (IL-13Rα2) over-expression on glioma cell, it was demonstrated to be a potential receptor for glioma targeting. In this study, Pep-1-conjugated PEGylated nanoparticles loaded with paclitaxel (Pep-NP-PTX) were developed as a targeting drug delivery system for glioma treatment.

miR-539 induces cell cycle arrest in nasopharyngeal carcinoma by targeting cyclin-dependent kinase 4.

Dysregulation of microRNAs has been demonstrated to contribute to malignant progression of cancers, including nasopharyngeal carcinoma (NPC). miR-539 was previously reported to be significantly downregulated in osteosarcoma. However, the potential role and mechanism of action of miR-539 in the initiation and progression of NPC remain largely unknown.

Enhanced anti-ischemic stroke of ZL006 by T7-conjugated PEGylated liposomes drug delivery system.

The treatment for ischemic stroke is one of the most challenging problems and the therapeutic effect remains unsatisfied due to the poor permeation of drugs across the blood brain barrier (BBB). In this study, HAIYPRH (T7), a peptide that targeted to transferrin receptor (TfR) can mediate the transport of nanocarriers across the BBB, was conjugated to liposomes for ischemic stroke targeting treatment of a novel neuroprotectant (ZL006). T7-conjugated PEGylated liposomes (T7-P-LPs) loaded with ZL006 (T7-P-LPs/ZL006) were showed satisfactory vesicle size and size distribution.
