Abstract
Multidrug resistance (MDR) and metastasis are the major obstacles in cancer chemotherapy. Nanotechnology-based combination therapy is a useful strategy. Recently, the combination of biologics and small drugs has attracted much attention in cancer therapy. Yet, the treatment outcomes are often compromised by the different pharmacokinetic profiles of the co-administered drugs thus leading to inconsistent drug uptake and suboptimal drug combination at the tumor sites. Nanotechnology-based co-delivery offers a promising method to address this problem, which is well demonstrated in the use of small drug combinations. However, co-delivery of the drugs bearing different physicochemical properties (e.g., proteins and small drugs) remains a formidable challenge. Herein, we developed a self-assembled nanosystem for co-delivery of trichosanthin (TCS) protein and albendazole (ABZ) as a combination therapy for overcoming MDR and metastasis. TCS is a ribosome-inactivating protein with high antitumor activity. However, the druggability of TCS is poor due to its short half-life, lack of tumor-specific action, and low cell uptake. ABZ is a clinically used antihelmintic drug, which can also inhibit tubulin polymerization and thus serve as a potential antitumor drug. In our work, ABZ was encapsulated in the albumin-coated silver nanoparticles (termed ABZ@BSA/Ag NP). The thus-formed NPs were negatively charged and could tightly bind with the cationic TCS that was modified with a cell-penetrating peptide (CPP) low-molecular-weight protamine (termed rTL). Via the stable charge interaction, the nanosystem (rTL/ABZ@BSA/Ag NP) was self-assembled, and featured by the TCS corona. The co-delivery system efficiently inhibited the proliferation of the drug-resistant tumor cells (A549/T and HCT8/ADR) by impairing the cytoskeleton, arresting the cell cycle, and enhancing apoptosis. In addition, the migration and invasion of tumor cells were inhibited presumably due to the impeded cytoskeleton functions. The anti-MDR effect was further confirmed by the in vivo studies with the subcutaneous A549/T tumor mouse model. More importantly, the co-delivery system was demonstrated to be able to inhibit metastasis. The co-delivery system of TCS/ABZ provided a potential strategy for both overcoming drug resistance and inhibiting tumor metastasis.

Abstract
Malignant glioma is one of the most untreatable cancers because of the formidable blood-brain barrier (BBB), through which few therapeutics can penetrate and reach the tumors. Biologics have been booming in cancer therapy in the past two decades, but their application in brain tumor has long been ignored due to the impermeable nature of BBB against effective delivery of biologics. Indeed, it is a long unsolved problem for brain delivery of macromolecular drugs, which becomes the Holy Grail in medical and pharmaceutical sciences. Even assisting by targeting ligands, protein brain delivery still remains challenging because of the synthesis difficulties of ligand-modified proteins. Herein, we propose a rocket-like, multistage booster delivery system of a protein toxin, trichosanthin (TCS), for antiglioma treatment. TCS is a ribosome-inactivating protein with the potent activity against various solid tumors but lack of specific action and cell penetration ability. To overcome the challenge of its poor druggability and site-specific modification, intein-mediated ligation was applied, by which a gelatinase-cleavable peptide and cell-penetrating peptide (CPP)-fused recombinant TCS toxin can be site-specifically conjugated to lactoferrin (LF), thus constructing a BBB-penetrating, gelatinase-activatable cell-penetrating nanohybrid TCS toxin. This nanohybrid TCS system is featured by the multistage booster strategy for glioma dual-targeting delivery. First, LF can target to the BBB-overexpressing low-density lipoprotein receptor-related protein-1 (LRP-1), and assist with BBB penetration. Second, once reaching the tumor site, the gelatinase-cleavable peptide acts as a separator responsive to the glioma-associated matrix metalloproteinases (MMPs), thus releasing to the CPP-fused toxin. Third, CPP mediates intratumoral and intracellular penetration of TCS toxin, thereby enhancing its antitumor activity. The BBB penetration and MMP-2-activability of this delivery system were demonstrated. The antiglioma activity was evaluated in the subcutaneous and orthotopic animal models. Our work provides a useful protocol for improving the druggability of such class of protein toxins and promoting their in-vivo application for targeted cancer therapy.

Abstract
It is highly desired that satisfactory photoactive agents with ideal photophysical characteristics are explored for potent cancer phototherapeutics. Herein, bifunctional nanoparticles of low-bandgap donor-acceptor (D-A)-type conjugated-polymer nanoparticles (CP-NPs) are developed to afford a highly efficient singlet-to-triplet transition and photothermal conversion for near-infrared (NIR) light-induced photodynamic (PDT)/photothermal (PTT) treatment. CP-NPs display remarkable NIR absorption with the peak at 782 nm, and perfect resistance to photobleaching. Photoexcited CP-NPs undergo singlet-to-triplet intersystem crossing through charge transfer in the excited D-A system and simultaneous nonradiative decay from the electron-deficient electron acceptor isoindigo derivative under single-wavelength NIR light irradiation, leading to distinct singlet oxygen quantum yield and high photothermal conversion efficiency. Moreover, the CP-NPs display effective cellular uptake and cytoplasmic translocation from lysosomes, as well as effective tumor accumulation, thus promoting severe light-triggered damage caused by favorable reactive oxygen species (ROS) generation and potent hyperthermia. Thus, CP-NPs achieve photoactive cell damage through their photoconversion ability for synergistic PDT/PTT treatment with tumor ablation. The proof-of-concept design of D-A-type conjugated-polymer nanoparticles with ideal photophysical characteristics provides a general approach to afford potent photoactive cancer therapy.

Abstract
This work aims at developing an immunotherapeutic strategy to deliver a cancer DNA vaccine targeting dendritic cells (DCs), to trigger their maturation and antitumor function, and reduce immune escape using a polymeric nanocomplex of paclitaxel (PTX)-encapsulated sulfobutylether-β-cyclodextrin (SBE)/mannosylated N,N,N-trimethylchitosan (mTMC)/DNA. To enhance DC-targeting and revoke immunosuppression is the major challenge for eliciting effective antitumor immunity. This codelivery system is characterized by using low-dose PTX as an adjuvant that is included inside SBE, and the PTX/SBE further serves as an anionic crosslinker to self-assemble with the cationic mTMC/DNA polyplexes. This system is used in combination with a microneedle for transcutaneous vaccination. Once penetrating into the epidermis, the mannosylated nanocomplexes would preferentially deliver the pTRP-2 DNA vaccine inside the DCs. Phenotypic maturation is demonstrated by the increased expression of costimulatory molecules of CD80 and CD86, and the elevated secretion of IL-12p70. The mixed leucocyte reactions reveal that the PTX/SBE-mTMC/DNA nanocomplexes enhance the proliferation of CD4+ and CD8+ T cells, and inhibit the generation of immune-suppressive FoxP3+ T cells. The system shows high antitumor efficacy in vivo. The PTX/SBE-mTMC/DNA nanocomplexes for DC-targeted codelivery of DNA vaccine and adjuvant PTX yield synergistic effects on the DC maturation and its presenting functions, thus increasing immune stimulation and reducing immune escape.

Abstract
Gene therapy represents a promising cancer treatment featuring high efficacy and limited side effects, but it is stymied by a lack of safe and efficient gene-delivery vectors. Cationic polymers and lipid-based nonviral gene vectors have many advantages and have been extensively explored for cancer gene delivery, but their low gene-expression efficiencies relative to viral vectors limit their clinical translations. Great efforts have thus been devoted to developing new carrier materials and fabricating functional vectors aimed at improving gene expression, but the overall efficiencies are still more or less at the same level. This review analyzes the cancer gene-delivery cascade and the barriers, the needed nanoproperties and the current strategies for overcoming these barriers, and outlines PEGylation, surface-charge, size, and stability dilemmas in vector nanoproperties to efficiently accomplish the cancer gene-delivery cascade. Stability, surface, and size transitions (3S Transitions) are proposed to resolve those dilemmas and strategies to realize these transitions are comprehensively summarized. The review concludes with a discussion of the future research directions to design high-performance nonviral gene vectors.

Abstract
Current cancer nanomedicines can only mitigate adverse effects but fail to enhance therapeutic efficacies of anticancer drugs. Rational design of next-generation cancer nanomedicines should aim to enhance their therapeutic efficacies. Taking this into account, this review first analyzes the typical cancer-drug-delivery process of an intravenously administered nanomedicine and concludes that the delivery involves a five-step CAPIR cascade and that high efficiency at every step is critical to guarantee high overall therapeutic efficiency. Further analysis shows that the nanoproperties needed in each step for a nanomedicine to maximize its efficiency are different and even opposing in different steps, particularly what the authors call the PEG, surface-charge, size and stability dilemmas. To resolve those dilemmas in order to integrate all needed nanoproperties into one nanomedicine, stability, surface and size nanoproperty transitions (3S transitions for short) are proposed and the reported strategies to realize these transitions are comprehensively summarized. Examples of nanomedicines capable of the 3S transitions are discussed, as are future research directions to design high-performance cancer nanomedicines and their clinical translations.

Abstract
Drug-conjugated gold nanoparticles (GNPs), which are generally constructed with many molecules of thiol-terminated polyethylene glycol (PEG)-drug decorated on their surfaces via a thiol-Au covalent bond, are promising and efficient nanoprodrugs. However, because of the exposure of the hydrophobic drug molecules on the surface of the conjugate, in vivo stability, opsonization, and subsequent inefficient therapy become the main issues of this system. To solve these problems without complicating the structures of gold conjugates, herein we propose a method to change the relative position of PEG and the drug. A novel gold conjugate (GNP-NHN═Dox-mPEG) with doxorubicin (Dox) shielded by PEGylation on the surface of GNPs is designed. It demonstrates improved solubility, stability, and dispersion and achieves a two-step stimulus-responsive drug release in response to an acidic environment in lysosomes and then esterase in the cytoplasm. This unique manner of release enables the cytoplasm to act as a reservoir for sustained drug delivery into the nucleus to improve antitumor efficacy in vivo. The intratumoral drug concentrations of the conjugate reach 14.4 ± 1.4 μg/g at 8 h, a two-fold increase in the drug concentration compared with that of the doxorubicin hydrochloride group. This molecular design and regulation approach is facile but important in modulating the in vivo performance of nanovehicles and demonstrates its vital potential in developing effective nanoparticle-based drug delivery agents.

Abstract
Heparin is a kind of naturally occurring polymer with excellent biocompatibility and solubility. It is characterized by dense of negative charge, higher than any endogenous components. Heparin can bind with various cationic peptides and proteins, thereby providing a useful noncovalent linkage for building a drug delivery system. As a case in point, heparin/cell-penetrating peptides (CPP) interaction is strong, and remains stable in vivo. They can be used to modify different proteins, respectively, and subsequently, by simply mixing the modified proteins, a protein-protein conjugate can be form via the stable heparin/CPP linkage. This linkage could not be broken unless addition of protamine that bears higher cationic charge density than CPP, and CPP thus can be substituted and released. Of note, heparin is a potent antagonist of CPP, and their binding naturally inhibits CPP-mediated drug cell penetration. Based on this method, we developed a heparin-regulated macromolecular prodrug-type system, termed ATTEMPTS, for drug targeting delivery. In this review article, we mainly summary the application of ATTEMPTS in delivery of various macromolecular drugs for cancer therapy, and also introduce the heparin-regulated nanoprobes for tumor imaging.

Abstract
Multidrug resistance (MDR) is a main obstacle in cancer chemotherapy. The MDR mechanisms involve P-glycoprotein (P-gp) overexpression, abnormality of apoptosis-related protein, and altered expression of drug-targeting proteins. Therapeutic proteins are emerging as candidates for overcoming cancer MDR because of not only their large molecular size that potentially circumvents the P-gp-mediated drug efflux but also their distinctive bioactivity distinguished from small-molecular drugs. Herein we report trichosanthin, a plant protein toxin, possesses synergistic effect with paclitaxel (PTX) in the PTX-resistance A549/T nonsmall cell lung cancer (NSCLC) cells, by reversing PTX-caused caspase 9 phosphorylation and inducing caspase 3-dependent apoptosis. Moreover, via intein-mediated site-specific protein ligation, a matrix metalloproteinase (MMP)-activatable cell-penetrating trichosanthin delivery system was constructed by modification of a cell-penetrating peptide and MMP-2-sensitive PEGylation to overcome the limitation of in vivo application of trichosanthin, by improving the short half-life and poor tumor targeting, as well as immunogenicity. In a mouse model bearing A549/T tumor, the MMP-activatable trichosanthin was further tested for its application for MDR reversal in combination with PTX liposomes. The delivery system showed synergy effect with PTX-loaded liposome in treating MDR cancer in vivo.
