The prognosis of esophageal squamous cell carcinoma is poor. We hereby presented a highly integrated and clinically relevant precision nanomedicine strategy to target ESCC molecularly and physically for significant improvement of the treatment efficacy. We firstly identified PI3K overexpression in patient samples and its relation to poor patient survival. With our highly versatile tumor-targeted drug delivery platform (DCM), we were able to load a potent but toxic docetaxel (DTX) and a PI3K inhibitor (AZD8186) with favorable physical properties...

The synthesis procedure of nanoparticles based on thermal degradation produces organic solvent dispersible iron oxide nanoparticles (OA-IONP) with oleic acid coating and unique physicochemical properties of the core. Some glycosides with hydrophilic sugar moieties bound to oleyl hydrophobic chains have antimitotic activity on cancer cells but reduced in vivo applications because of the intrinsic low solubility in physiological media, and are prone to enzymatic hydrolysis. In this manuscript, we have synthetized and characterized OA-IONP-based micelles encapsulated within amphiphilic bioactive glycosides...

Gambogic acid (GA) possesses good anti-tumor efficacy in preclinical studies, however, its poor hydrophilicity, short blood circulation time and side effect limited its clinical application. In this work, monomethyl poly(ethylene glycol)-poly(ε-caprolactone) (MPEG-PCL) copolymer was synthesized and used to encapsulate GA by a facile one-step solid dispersion and form nano-sized micelles (GA micelles). The GA micelles exhibited small average particle size (29±2 nm), high encapsulation efficiency (92.1±0.3%), and long drug release time-in vitro...

The continuing increase of cancer morbidity and death rate requires efficient therapeutic strategies. The traditional chemotherapy usually fails to treat cancer or prolong survival rate due to its toxicity to normal cells, side effects and lack of targeting capacity. In recent years, nanomaterials have shown great potentials to treat various cancers efficiently. Graphene-based nanomaterials, especially graphene oxide (GO) and reduced GO (rGO), have arisen as promising candidates for cancer therapy. Due to their unique physicochemical and optical properties including the extremely large surface area, modifiable active groups, great biocompatibility and strong photothermal effect, they can act either as tunable carriers or active agents for advanced chemotherapeutics delivery and cancer therapy...

Lymph metastasis is a vital pathway of cancer cell dissemination, and insidious lymph node metastasis increases the risk of distant cancer metastasis. Current therapies for lymph metastasis are largely restricted by limited targeting and penetration capacity. Herein, we report that an r9 cell-penetrating peptide-based cabazitaxel nanovehicle (r9-CN) displays prominent lymph metastasis targeting and deep penetration ability after intravenous injection for effective anti-metastasis therapy. Methods: The r9-CN and CN nanovehicles were prepared by thin film dispersion, using DSPE-PEG2000 as the nano-carrier material and cabazitaxel as the model drug to fabricate r9-modified nano-micelles by self-assembly...

Singlet oxygen has won a great deal of attention to catalysis and biological studies due to its strong oxidizing properties. However, the photosensitizers which require for the generation of singlet oxygen remain inadequate because of their lack of long-wavelength absorption, weak hydrophilicity, and poor biocompatibility. Here, we develop near-infrared laser activated supramolecular photosensitizers (isophthalic acid/layered double hydroxide nanohybrids) for efficient two-photon photodynamic therapy. The singlet oxygen quantum yield of nanohybrid is up to 0...

Temozolomide (TMZ) is the current first-line chemotherapy for treatment of glioblastoma multiforme (GBM). However, similar to other brain therapeutic compounds, access of TMZ to brain tumors is impaired by the blood-brain barrier (BBB) leading to poor response for GBM patients. To overcome this major hurdle, we have synthesized a set of TMZ-encapsulating nanomedicines made of four cationic liposome (CL) formulations with systematic changes in lipid composition and physical-chemical properties. The targeting nature of this nanomedicine is provided by the recruitment of proteins, with natural targeting capacity, in the biomolecular corona (BC) layer that forms around CLs after exposure to human plasma (HP)...

RATIONALE: Multidrug resistance (MDR) occurs frequently and has a major challenge in tumor treatment. Lipid composition in cell membrane and the redox balance are closely associated with the development of MDR. The liquid extraction surface analysis in combination with mass spectrometry (LESA-MS) has the characteristics of minimal sample preparation, rapid analysis, high sensitivity and high throughput, and has obtained wide applications. METHODS: The LESA-MS was employed to in situ determine the lipids and other specific metabolites of intact MCF-7/ADR cells (adriamycin-resistant breast cancer cells) and its parental MCF-7/S cells grew on the glass slide...

Galactomannan isolated from the fruit rind of Punica granatum was previously reported to have excellent antioxidant, immunomodulatory and anticancer properties against both human and murine cancer cells. This polysaccharide was proved to be an anticancer agent either alone or as an adjuvant to chemotherapy. An exploration leads to the fabrication of silver nanoparticles with an average size around 30 nm and a negative surface charge of 35.2 mV using this biopolymer which acted both as reducing and capping agent and displayed good stability and biocompatibility...

The anti-PD-L1 monoclonal antibody (mAb) targeting PD-1/PD-L1 immune checkpoint has achieved outstanding results in clinical application and has become one of the most popular anti-cancer drugs. The mechanism of molecular recognition and inhibition of PD-L1 mAbs is not yet clear, which hinders the subsequent antibody design and modification. In this work, the trajectories of PD-1/PD-L1 and nanobody/PD-L1 complexes were obtained via comparative molecular dynamics simulations. Then, a series of physicochemical parameters including hydrogen bond, dihedral angle distribution, p K a value and binding free energy, and so forth, were all comparatively analyzed to investigate the recognition difference between PD-L1 and PD-1 and nanobody...

Utilizing the diverse features of biocompatible polymers to target drugs into the tumor/s has been a research hotspot since last decade. Such polymeric conjugates of anti-cancer drugs have proven their potential in providing sustained release of drugs with reduced systemic toxicity and improved tumor retention. Polymers like polyethylene glycol (PEG), N-(2-Hydroxypropyl) methacrylamide (HPMA), Polylactic-co-glycolic acid (PLGA), Polyamidoamine (PAMAM), and others remain exploited for their specific as well as shared characteristics in the rational delivery of anti-cancer agents...

Chemotherapy using cytotoxic agents, such as paclitaxel (PTX), is one of the most effective treatments for advanced ovarian cancer. However, due to nonspecific targeting of the drug and the presence of toxic solvents required for dissolving PTX prior to injection, there are several serious side effects associated with this treatment. In this study, we explored self-assembled lipid-based nanoparticles as PTX carriers, which were able to improve its antitumour efficacy against ovarian cancer. The nanoparticles were also functionalized with epidermal growth factor receptor (EGFR) antibody fragments to explore the benefit of tumor active targeting...

Programmed death-ligand 1 (PD-L1) is a critical regulator to defend tumor cells against immune surveillance. Thyroid hormone has been shown to induce PD-L1 expression in cancer cells. Its nano-particulated analogue, nano-diamino-tetrac (NDAT; Nanotetrac) is an anticancer/anti-angiogenic agent. In the current study, the inhibitory mechanism by which NDAT inhibited PD-L1 mRNA abundance and PD-L1 protein content in oral cancer cells was investigated. NDAT inhibited inducible PD-L1 expression and protein accumulation by the inhibition of activated ERK1/2 and PI3K...

Despite several advancements in the biomedical sciences, an efficient cancer therapy still remains a challenge. Nanomedicines have shown potential to overcome certain roadblocks faced in the existing treatment modalities. Losartan potassium (LP) which is a known vasodilator also exhibits anti fibrolytic and anti-metastatic properties altogether. Further, also being a potential angiotensin II type 1 receptor antagonist, it has been well explored for down regulating tumourogenic biomarkers like VEGF-A (Vascular endothelial growth factor A) and suppression of neovascularization, making it a suitable drug to target for cancer treatment...
