Abstract
BACKGROUND Cervical cancer chemotherapy calls for the efficiently delivery of anticancer drug into cancer cells by nanoparticles. In this study, folate (FA) modified, cisplatin (CIS)-loaded nanostructured lipid carriers (NLCs) were constructed and evaluated. METHODS FA containing polyethylene glycol (PEG)-distearoylphosphatidylethanolamine (DSPE) (FA-PEG-DSPE) was synthesized. FA-PEG-DSPE modified, CIS-loaded NLCs (FA-CIS-NLCs) were prepared. Their particle size, zeta potential, drug encapsulation efficiency (EE) and in vitro delivery behavior were evaluated. In vitro cytotoxicity study of FA-CIS-NLCs was tested in human cervix adenocarcinoma cell line (HeLa cells). In vivo anti-tumor efficacies of the carriers were evaluated on a mice-bearing cervical cancer model. RESULTS The optimum FA-CIS-NLCs formulations have a particle size of 143.2 nm and a +25.7 mV surface charge. FA-CIS-NLCs displayed the best anti-tumor activity than other formulations in vitro and in vivo. CONCLUSIONS The results demonstrated that FA-CIS-NLCs were efficient in selective delivery to cancer cells over-expressing FA receptors (FRs). FA-CIS-NLCs targeted transfer CIS to the cervical cancer cells, enhance the anti-tumor capacity. The novel constructed NLCs could function as outstanding nanocarriers for the delivery of drugs for the targeted treatment of cervical cancers.

Polymeric complex micelles with double drug-loading strategies for folate-mediated paclitaxel delivery. Colloids Surf B Biointerfaces 2015; 131:191-201. [PMID: 25988283 DOI: 10.1016/j.colsurfb.2015.04.057] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/03/2015] [Revised: 04/15/2015] [Accepted: 04/27/2015] [Indexed: 02/07/2023]
Abstract
Drug loading is a key procedure in the preparation of drug-loaded nano-carriers. In this study, the paclitaxel (PTX)-loaded polymeric complex micelles (FA-P123-PTX/PTX micelles) with double drug-loading strategies were designed and prepared to improve the drug loading percentage of carriers and its anti-tumor efficiency. PTX was simultaneously conjugated to pluronic P123 (P123) polymer and encapsulated inside the P123 complex micelle. Folate (FA) was linked to the surface of micelles for the active target delivery of micelles to tumor cells. The FA-P123-PTX/PTX micelles showed spherical shaped with high drug loading of 18.08±0.64%. The results of cellular uptake studies suggested that FA could promote the internalization of micelles into the FR positive cells. FA-P123-PTX/PTX micelles showed significant higher anti-tumor activity against FR positive tumor cells compared to Taxol(®) (p<0.05). Moreover, the FA-P123-PTX/PTX micelles exhibited higher anti-tumor efficacy in B16 bearing mice with better safety property compared with Taxol(®). These results suggested that FA-P123-PTX/PTX micelles with double drug-loading strategies showed great potential for targeted delivery of anti-cancer drugs.

Co-delivery of doxorubicin and siRNA by a simplified platform with oligodeoxynucleotides as a drug carrier. Colloids Surf B Biointerfaces 2015; 126:531-40. [PMID: 25618822 DOI: 10.1016/j.colsurfb.2015.01.006] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2014] [Revised: 12/26/2014] [Accepted: 01/04/2015] [Indexed: 12/14/2022]
Abstract
The greatest challenge in combining chemotherapy and gene therapy is the construction of a suitable platform for the co-delivery of the drug and the therapeutic gene. In this study, a simplified and effective system for the co-loading and intracellular co-delivery of doxorubicin (Dox) and siRNA was developed. Oligodeoxynucleotides with CGA repeating units (CGA-ODNs) were introduced to load Dox. The loading mechanism was based on the ability of Dox to intercalate within double-stranded 5'-GC-3' or 5'-CG-3' sequences. Poly(ethyleneimine) (PEI) was used to condense siRNA and Dox loaded CGA-ODNs (CGA-ODNs-Dox) to obtain Dox and siRNA co-loaded nanocomplexes (PEI/CGA-ODNs-Dox&siRNA, PDR). The cellular uptake of PDR in A549 and HepG2 cells was 39.52% and 36.78%, respectively, indicating that the co-loading and co-delivery effect was achieved through the mono-loading method. An in vitro drug release study indicated that CMCS-poly(ethylene glycol) (PEG)-NGR (CPN) modified PDR (CPN-PDR) displayed a pH-triggered drug release property due to the reversed surface charge of CMCS in an acidic environment. Cellular uptake studies also confirmed that the disassembly of CPN-PDR was induced by an acidic pH in the extracellular matrix. Moreover, lysosomal escape of both Dox and siRNA was observed. Successful accumulation of Dox in the cell nucleus and siRNA in the cytoplasm was also demonstrated. Consequently, the novel construction of a simplified loading method and high co-delivery efficiency was proven to be a promising platform for the co-delivery of drug and siRNA.

Abstract
The majority of drugs and biomolecules need to be delivered into cells to be effective. However, the cell membranes, a biological barrier, strictly resist drugs or biomolecules entering cells, resulting in significantly reduced intracellular delivery efficiency. To overcome this barrier, a variety of intracellular delivery approaches including chemical and physical ways have been developed in recent years. In this review, the focus is on summarizing the nanomaterial routes involved in making use of a collection of receptors for the targeted delivery of drugs and biomolecules and the physical ways of applying micro- and nanotechnologies for high-throughput intracellular delivery.

The enhanced longevity and liver targetability of Paclitaxel by hybrid liposomes encapsulating Paclitaxel-conjugated gold nanoparticles. Int J Pharm 2014; 477:408-15.

Abstract
Organic and inorganic drug delivery systems both demonstrate their own advantages and challenges in practical applications. Combining these two drug delivery strategies in one system is expected to solve their current issues and achieve desirable functions. In this paper, gold nanoparticles (GNPs) and liposomes have been chosen as the model systems to construct a hybrid system and investigate its performance for the tumor therapy of Paclitaxel (PTX). The thiol-terminated polyethylene glycol (PEG400)-PTX derivative has been covalently modified on the surface of GNPs, followed by the encapsulation of PTX-conjugated GNPs (PTX-PEG400@GNPs) in liposomes. The hybrid liposomes solve the solubility and stability problems of gold conjugates and show high drug loading capacity. In vitro PTX release from the hybrid system maintains the similar sustained behavior demonstrated in its conjugates. Under the protection of a biocompatible liposome shell, encapsulated PTX shows enhanced circulation longevity and liver targetability compared to Taxol(®) and PTX-PEG400@GNPs suspension in the pharmacokinetic and biodistribution studies. These indicate that encapsulating drug-conjugated inorganic nanoparticles inside organic carriers maintains the superiority of both vehicles and improves the performance of hybrid systems. Although these attributes of hybrid liposomes lead to a better therapeutic capacity in a murine liver cancer model than that of the comparison groups, it shows no significant difference from Taxol(®) and conjugate suspension. This result could be due to the delayed and sustained drug release from the system. However, it indicates the promising potential for these hybrid liposomes will allow further construction of a compound preparation with improved performance that is based on their enhanced longevity and liver targetability of Paclitaxel.

Abstract
A multifunctional pH-sensitive polymeric nanoparticle system was developed for simultaneous tumor magnetic resonance imaging (MRI) and therapy. The nanoparticles were self-assembled using the multi-block polymer poly(lactic acid)-poly(ethylene glycol)-poly(l-lysine)-diethylenetriamine pentaacetic acid (PLA-PEG-PLL-DTPA) and the pH-sensitive material poly(l-histidine)-poly(ethylene glycol)-biotin (PLH-PEG-biotin). The anti-hepatocellular carcinoma (HCC) drug sorafenib was encapsulated inside the nanoparticles. Gd ions were chelated to the DTPA groups which were distributed on the nanoparticle surface. Biotinylated vascular endothelial growth factor receptor (VEGFR) antibodies were linked to the surface biotin groups of nanoparticles through the avidin linker to form the target pH-sensitive theranostic nanoparticles (TPTN). TPTN exhibited spherical or ellipsoidal shapes, uniform particle size distribution (181.4 ± 3.4 nm), positive zeta potential (14.95 ± 0.60 mV), high encapsulation efficiency (95.02 ± 1.47%) and drug loading (2.38 ± 0.04%). The pH-sensitive sorafenib release from TPTN was observed under different pH values (47.81% at pH = 7.4 and 99.32% at pH = 5.0, respectively). In cell cytotoxicity studies, TPTN showed similar antitumor effect against HepG2 cells compared to solubilized sorafenib solution after pre-incubation in acid PBS (pH = 5.0) for 1 h in vitro (P > 0.05). In in vivo anti-tumor studies, TPTN showed significantly higher antitumor effect in H22 tumor (VEGFR overexpressed cell line) bearing mice compared to the solubilized sorafenib solution (oral or i.v. administration) group (P < 0.05). In the MRI test, the T1 relaxivity value of TPTN was 17.300 mM(-1) s(-1) which was 3.6 times higher than Magnevist® (r1 = 4.8 mM(-1) s(-1)). As a positive contrast agent, TPTN exhibited higher resolution and longer imaging time (more than 90 min) in the MRI diagnosis of tumor-bearing mice compared to Magnevist® (more than 60 min). Furthermore, histological examination of TBN (blank TPTN, without sorafenib loaded) showed no visible tissue toxicity compared to normal saline. Thus, TPTN possessed dual-loading drugs and imaging agents, active targeting and pH-triggered drug release properties in one platform with good biocompatibility. All of these results indicated that TPTN was a promising theranostic carrier which could be a platform for the development of novel multifunctional theranostic agents.

Abstract
![]()
Docetaxel
(DCX) is a second generation taxane. It is approved by
the U.S. Food and Drug Administration for the treatment of various
types of cancer, including breast, non-small cell lung, and head and
neck cancers. However, side effects, including those related to Tween
80, an excipient in current DCX formulations, can be severe. In the
present study, we developed a novel solid lipid nanoparticle (SLN)
composition of DCX. Trimyristin was selected from a list of high melting
point triglycerides as the core lipid component of the SLNs, based
on the rate at which the DCX was released from the SLNs and the stability
of the SLNs. The trimyristin-based, PEGylated DCX-incorporated SLNs
(DCX-SLNs) showed significantly higher cytotoxicity against various
human and murine cancer cells in culture, as compared to DCX solubilized
in a Tween 80/ethanol solution. Moreover, in a mouse model with pre-established
tumors, the new DCX-SLNs were significantly more effective than DCX
solubilized in a Tween 80/ethanol solution in inhibiting tumor growth
without toxicity, likely because the DCX-SLNs increased the concentration
of DCX in tumor tissues, but decreased the levels of DCX in major
organs such as liver, spleen, heart, lung, and kidney. DCX-incorporated
SLNs prepared with one or more high-melting point triglycerides may
represent an improved DCX formulation.

Synergistic enhancement of cancer therapy using a combination of ceramide and docetaxel. Int J Mol Sci 2014; 15:4201-20.

Abstract
Ceramide (CE)-based combination therapy (CE combination) as a novel therapeutic strategy has attracted great attention in the field of anti-cancer therapy. The principal purposes of this study were to investigate the synergistic effect of CE in combination with docetaxel (DTX) (CE + DTX) and to explore the synergy mechanisms of CE + DTX. The 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and combination index (CI) assay showed that simultaneous administration of CE and DTX with a molar ratio of 0.5:1 could generate the optimal synergistic effect on murine malignant melanoma cell (B16, CI = 0.31) and human breast carcinoma cell (MCF-7, CI = 0.48). The apoptosis, cell cycle, and cytoskeleton destruction study demonstrated that CE could target and destruct the microfilament actin, subsequently activate Caspase-3 and induce apoptosis. Meanwhile, DTX could target and disrupt the microtubules cytoskeleton, leading to a high proportion of cancer cells in G2/M-phase arrest. Moreover, CE plus DTX could cause a synergistic destruction of cytoskeleton, which resulted in a significantly higher apoptosis and a significantly higher arrest in G2/M arrest comparing with either agent alone (p < 0.01). The in vivo antitumor study evaluated in B16 tumor-bearing mice also validated the synergistic effects. All these results suggested that CE could enhance the antitumor activity of DTX in a synergistic manner, which suggest promising application prospects of CE + DTX combination treatment.

Abstract
Vascular endothelial growth factor receptor 2 (VEGFR2) is a potential cell-type biomarker in clinical diagnoses. Besides, it's the target protein of many tyrosine kinase inhibitors and its expression significantly associates with clinical performance of these inhibitors. VEGFR2 detection provides an early warning for diseases and a basis for therapy and drug screening. Some methods have been developed for VEGFR2 determination. However, they are usually performed indirectly and complexly. Herein, an electrochemical biosensing platform for VEGFR2 analysis has been first proposed. It can detect the total concentrations of the VEGFR2 protein in cells lysates directly and can be used to monitor the changes of VEGFR2 expression levels induced by treatments of different inhibitors. Moreover, the inhibitor-VEGFR2 interactions are illuminated through theoretical simulation. The simulation results agree well with the experimental data, indicating the veracity of the proposed method. The electrochemical detection methodology for VEGFR2 would be promising in clinical diagnosis and drug screening.

Abstract
Docetaxel has been recognized as one of the most efficient anticancer drugs over the past decade; however, its poor water solubility and systemic toxicity have greatly limited its clinical application. In recent decades, the emergence of nanotechnology has provided new drug delivery systems for docetaxel, which can improve its water solubility, minimize the side effects and increase the tumor-targeting distribution by passive or active targeting. This review focuses on the research progress in nanoformulations related to docetaxel delivery – such as polymer-based, lipid-based, and lipid-polymer hybrid nanocarriers, as well as inorganic nanoparticles – addressing their structures, characteristics, preparation, physicochemical properties, methods by which drugs are loaded into them, and their in vitro and in vivo efficacies. Further, the targeted ligands used in the docetaxel nanoformulations, such as monoclonal antibodies, peptides, folic acid, transferrin, aptamers and hyaluronic acid, are described. The issues to overcome before docetaxel nanoformulations can be used in clinical and commercial applications are also discussed.

Abstract
Aim: The authors studied the bioimaging and delivery of drug-entrapped, nanostructured lipid carriers with quantum dots (QDs), called QDNLCs, for integrating imaging and therapy. Materials & methods: Nanostructured lipid carriers consisting of QDs, including lipophilic QDs, carboxyl-function QDs or PEG QDs were prepared. Application of the nanocarriers was evaluated by cytotoxicity, cell migration, cellular uptake, in vivo real-time tumor monitoring and drug accumulation in tumors. Results: All QDNLCs exhibited a size of 245 nm with camptothecin encapsulation of >99%. Cytotoxicity of the nanoparticles against melanoma cells was superior to that of free camptothecin. Carboxylic acid-conjugated QDNLCs (C-QDNLCs) showed the highest cell internalization and in vivo fluorescence labeling compared with the other carriers. Real-time bioimaging demonstrated that C-QDNLCs maintained signaling in tumors for at least 24 h. The camptothecin accumulation in melanomas increased by 6.4-fold after incorporation into C-QDNLCs. Conclusion: For the first time, nanostructured lipid carriers were coordinated with QDs and an anticancer drug to provide efficient tumor imaging and drug delivery.

Abstract
Ala-Glu-Tyr-Leu-Arg (AEYLR) was identified as a small peptide ligand targeting epidermal growth factor receptors (EGFR) in vitro in our previous study. The in vivo targeting ability of AEYLR and AEYLR-conjugated nanostructured lipid carriers (NLC) was studied in this paper. Near-infrared fluorescent (NIFR) dye 1,1'-dioctadecyltetramethyl indotricarbocyanine iodide (DiR)-loaded and AEYLR-modified NLC (A-D-NLC) were prepared. The average diameter, zeta potential, coupling efficiency between AEYLR and NLC and the amount of DiR released from A-D-NLC were used to evaluate their in vivo characteristics. AEYLR was labeled by Cy7 and A549 xenograft tumor-bearing mice model were establish. The in vivo distribution in tumor-bearing mice of A-D-NLC and Cy7-AEYLR was examined using NIRF imaging experiments at different times post-injection. AEYLR and AEYLR-conjugated NLC showed obvious targeting to A549 xenograft tumor compared with the control group. These results suggested that AEYLR-modified NLC could be considered as a promising targeted delivery system for combination cancer chemotherapy to improve therapeutic efficacy and to minimize adverse effects.

Abstract
The epidermal growth factor receptor (EGFR) serves an important function in the proliferation of tumors in humans and is an effective target for the treatment of cancer. In this paper, we studied the targeting characteristics of small peptides (AEYLR, EYINQ, and PDYQQD) that were derived from three major autophosphorylation sites of the EGFR C-terminus domain in vitro. These small peptides were labeled with fluorescein isothiocyanate (FITC) and used the peptide LARLLT as a positive control, which bound to putative EGFR selected from a virtual peptide library by computer-aided design, and the independent peptide RALEL as a negative control. Analyses with flow cytometry and an internalization assay using NCI-H1299 and K562 with high EGFR and no EGFR expression, respectively, indicated that FITC-AEYLR had high EGFR targeting activity. Biotin-AEYLR that was specifically bound to human EGFR proteins demonstrated a high affinity for human non-small-cell lung tumors. We found that AEYLR peptide-conjugated, nanostructured lipid carriers enhanced specific cellular uptake in vitro during a process that was apparently mediated by tumor cells with high-expression EGFR. Analysis of the MTT assay indicated that the AEYLR peptide did not significantly stimulate or inhibit the growth activity of the cells. These findings suggest that, when mediated by EGFR, AEYLR may be a potentially safe and efficient delivery ligand for targeted chemotherapy, radiotherapy, and gene therapy.

Abstract
Targeting of drugs and their carrier systems by using receptor-mediated endocytotic pathways was in its nascent stages 25 years ago. In the intervening years, an explosion of knowledge focused on design and synthesis of nanoparticulate delivery systems as well as elucidation of the cellular complexity of what was previously-termed receptor-mediated endocytosis has now created a situation when it has become possible to design and test the feasibility of delivery of highly specific nanoparticle drug carriers to specific cells and tissue. This review outlines the mechanisms governing the major modes of receptor-mediated endocytosis used in drug delivery and highlights recent approaches using these as targets for in vivo drug delivery of nanoparticles. The review also discusses some of the inherent complexity associated with the simple shift from a ligand-drug conjugate versus a ligand-nanoparticle conjugate, in terms of ligand valency and its relationship to the mode of receptor-mediated internalization.

Abstract
The purpose of this study was to develop two novel drug delivery systems based on biodegradable docetaxel-lipid-based-nanosuspensions. The first one was poly(ethylene glycol)- modified docetaxel-lipid-based-nanosuspensions (pLNS). It was developed to increase the cycle time of the drug within the body and enhance the accumulation of the drug at the tumor site. The second one was targeted docetaxel-lipid-based-nanosuspensions (tLNS) using folate as the target ligand. The tLNS could target the tumor cells that overexpressed folate receptor (FR). The morphology, particle size, and zeta potential of pLNS and tLNS were characterized, respectively. The in vitro cytotoxicity evaluation of Duopafei®, pLNS, and tLNS were performed in human hepatocellular liver carcinoma HepG2 (FR−) and B16 (FR+) cells, respectively. The in vivo antitumor efficacy and pharmacokinetics, as well as the drug tissue distribution, were evaluated in Kunming mice bearing B16 cells. The particle size of pLNS was 204.2 ± 6.18 nm and tLNS had a mean particle size of 220.6 ± 9.54 nm. Cytotoxicity of tLNS against B16 (FR+) cell lines was superior to pLNS (P < 0.05), while there was no significant difference in the half maximum inhibitory concentration values for HepG2 (FR−) cells between pLNS and tLNS. The results of the in vivo antitumor efficacy evaluation showed that tLNS exhibited higher antitumor efficacy by reducing tumor volume (P < 0.01) compared with Duopafei and pLNS, respectively. The results of the in vivo biodistribution study indicate that the better antitumor efficacy of tLNS was attributed to the increased accumulation of the drug in the tumor.

Abstract
Taxanes have been recognized as a family of very efficient anticancer drugs, but the formulation in use for the two main taxanes-Taxol for paclitaxel and Taxotere for docetaxel-have shown dramatic side effects. Whereas several new formulations for paclitaxel have recently appeared, such as Abraxane and others currently in various phases of clinical trials, there is no new formulation in clinical trials for the other main taxane, docetaxel, except BIND-014, a polymeric nanoparticle, which recently entered phase I clinical testing. Therefore, we review herein the state of the art and recent abundance in published results of academic approaches toward nanotechnology-based drug-delivery systems containing nanocarriers and targeting agents for docetaxel formulations. These efforts will certainly enrich the spectrum of docetaxel treatments in the near future. Taxotere's systemic toxicity, low water solubility, and other side effects are significant problems that must be overcome. To avoid the limitations of docetaxel in clinical use, researchers have developed efficient drug-delivery assemblies that consist of a nanocarrier, a targeting agent, and the drug. A wide variety of such engineered nanosystems have been shown to transport and eventually vectorize docetaxel more efficiently than Taxotere in vitro, in vivo, and in pre-clinical administration. Recent progress in drug vectorization has involved a combined therapy and diagnostic ("theranostic") approach in a single drug-delivery vector and could significantly improve the efficiency of such an anticancer drug as well as other drug types.
