Abstract
The development of drug delivery systems with high drug loading capacity, low leakage at physiological pH, and rapid release at the lesion sites remains an ongoing challenge. In this work, core-shell poly(6-O-methacryloyl-D-galactose)@poly(tert-butyl methacrylate) (PMADGal@PtBMA) nanoparticles (NPs) of sub-50 nm are facilely synthesized by reversible addition-fragmentation chain transfer (RAFT) soap-free emulsion polymerization with the assistance of 12-crown-4. A hydrophilic poly(methacrylic acid) (PMAA) core can then be revealed after deprotection of the tert-butyl groups, which is negatively charged and can adsorb nearly 100% of incubated doxorubicin (DOX) from a solution at pH 7.4. The physical shrinkage of PMAA chains below pH 6.0 endows the core with the squeezing effect, therefore realizing rapid drug release. It is demonstrated that the DOX release rate of PMADGal@PMAA NPs at pH 5 was 4 times that at pH 7.4. Cellular uptake experiments confirm the high targeting ability of the galactose modified PMADGal shell to human hepatocellular carcinoma (HepG2) cells. The fluorescence intensity of DOX in HepG2 cells is 4.86 times that of HeLa cells after 3 h incubation. Moreover, 20% cross-linked NPs show the highest uptake efficiency by HepG2 cells due to their moderate surface charge, size and hardness. In summary, both the core and the shell of PMADGal@PMAA NPs promise the rapid site-specific release of DOX in HepG2 cells. This work provides a facile and an effective strategy to synthesize core-shell NPs for hepatocellular carcinoma targeting therapy.

Abstract
Bortezomib (BTZ) is the first proteasome inhibitor approved by the Food and Drug Administration. It can bind to the amino acid residues of the 26S proteasome, thereby causing the death of tumor cells. BTZ plays an irreplaceable role in the treatment of mantle cell lymphoma and multiple myeloma. Moreover, its use in the treatment of other hematological cancers and solid tumors has been investigated in numerous clinical trials and preclinical studies. Nevertheless, the applications of BTZ are limited due to its insufficient specificity, poor permeability, and low bioavailability. Therefore, in recent years, different BTZ-based drug delivery systems have been evaluated. In this review, we firstly discussed the functions of proteasome inhibitors and their mechanisms of action. Secondly, the properties of BTZ, as well as recent advances in both clinical and preclinical research, were reviewed. Finally, progress in research regarding BTZ-based nanoformulations was summarized.

RESEARCH 2020; 2020:8970135.

Abstract
Intravesical chemotherapy has been recommended after the gold standard of transurethral resection of the bladder tumor to prevent bladder cancer (BC) from local recurrence in the clinic. However, due to rapid urine excretion and barrier protection of the bladder wall, the clinical performances of chemotherapeutic drugs are severely compromised. In the present work, a smart positively charged disulfide-crosslinked nanogel of oligoarginine-poly(ethylene glycol)–poly(L-phenylalanine-co-L-cystine) (R9-PEG–P(LP-co-LC)) was prepared to prolong the retention period and enhance the penetration capability of chemotherapeutic agent toward the bladder wall. PEG significantly improved the aqueous dispersibility of the 10-hydroxycamptothecin (HCPT)-loaded R9-PEG–P(LP-co-LC) (i.e., R9NG/HCPT) and enhanced the mucoadhesive capability by the nonspecific interaction between PEG chain and the bladder mucosa accompanied with the electrostatic interaction between the cationic R9 and negatively charged bladder mucosa. Besides, R9, as a cell-penetrating peptide, efficiently penetrated through the cell membrane and delivered carried cargo. The disulfide bond endowed the selective release behavior of HCPT triggered by the intracellular reductive microenvironment. As an advanced chemotherapeutic nanoformulation, the smart R9NG/HCPT demonstrated superior cytotoxicity against human BC 5637 cells in vitro and remarkably enhanced tumor suppression activity toward orthotopic BC models of mouse and rat in vivo, indicating its great potential in the clinical intravesical BC chemotherapy.

Abstract
The poor solubility and permeability of most chemotherapeutic drugs lead to unsatisfactory bioavailability combined with insufficient drug concentration. In this study, positively charged nanoparticles based on chitosan were developed and synthesized to enhance tumor penetration capability of 10-Hydroxycamptothecin (HCPT) in order to improve the chemotherapeutic effect of melanoma. The HCPT encapsulated nanoparticles were noted as NPs/HCPT. NPs/HCPT was characterized by dynamic light scattering and zeta potential measurements. In addition, cell uptake, in vitro cytotoxicity, apoptosis and in vivo antitumor activity of NPs/HCPT were further investigated. The average diameter of NPs/HCPT was approximately 114.6 ± 4.1 nm. The viability of murine melanoma cell lines (B16F10 and B16F1) was significantly decreased due to interaction with NPs/HCPT. Moreover, NPs/HCPT significantly inhibited the progression of tumors. These investigations implied that cationic NPs/HCPT could be potentially applied as a promising drug delivery nanosystem.

Abstract
Cancer-specific bioimaging has been correlated with fluorescence-guided tumor therapy, garnering extensive interest from researchers. Herein, a highly efficient tumor-targeting fluorescent probe (NP-001), which is integrated with 4-hydroxy-1,8-naphthalimide and NVP-AUY922, for tumor imaging has been established. 4-Hydroxy-1,8-naphthalimide is a fluorescent molecule with remarkable imaging compatibility. NVP-AUY922 is a heat shock protein 90 (HSP90) inhibitor with preferential tumor selectivity that is conjugated to 4-hydroxy-1,8-naphthalimide as a tumor-targeting ligand. NP-002, a resorcinol-blocked probe which prevented binding with an amino acid residue of the HSP90 ATP binding pocket, was also synthesized as a control. In vitro and ex vivo assays showed that NP-001 could arrest cell proliferation, induce apoptosis and accumulate to inhibit HSP90. Confocal laser scanning microscopy (CLSM) also confirmed that NP-001 could be selectively internalized by tumor cells for cancer-specific bioimaging. Moreover, pharmacokinetic studies and histological analysis also indicated that NP-001 had a relatively longer retention time and showed no major organ-related toxicities. Overall, these encouraging data suggest that NP-001 is a promising new candidate for the early diagnosis of metastatic disease as well as targeted tumor imaging.

Abstract
Bortezomib (BTZ) is a proteasome inhibitor as approved by US FDA for the treatment of multiple myeloma. It exhibits significant anti-cancer properties, against solid tumors; but lacks aqueous solubility, chemical stability which hinders its successful formulation development. The present study is an attempt to deliver BTZ using N-(2-hydroxypropyl) methacrylamide (HPMA) based copolymeric conjugates and biotinylated PNPs in an effective manner. Study describes a systematic synthetic pathway to synthesize functional polymeric conjugates such as HPMA-Biotin (HP-BT) HPMA-Polylactic acid (HPLA) and HPMA-PLA-Biotin (HPLA-BT) followed by exhaustive characterization both spectroscopically and microscopically. Our strategy yielded polymeric nanoparticles (PNPs) of narrow size range of 199.7 ± 1.32 nm. Release studies were performed at pH 7.4 and 5.6. PNPs were 2-folds less hemolytic (p < 0.0001) than pure drug. BTZ loaded PNPs of HPLA-BT demonstrated significant anti-cancer activity against MCF-7 cells. IC50 value of these PNPs was 56.06 ± 0.12 nM, which was approximately two folds less than BTZ (p < 0.0001). Cellular uptake study confirmed that higher uptake of formulations might be an outcome of biotin surface tethering characteristics that enhanced selectivity and targeting of formulations efficiently. In vivo pharmacokinetics evidenced increased bioavailability (AUC0 t-∞) of DL-HPLA-BT PNPs (drug loaded) than BTZ with an improved half-life. Overall the developed PNPs led to the improved and effective BTZ delivery.

Abstract
Many candidate anticancer drugs have suffered from their intrinsic hydrophobicity, which poses several obstacles for clinical application. To overcome this challenge and further improve the performance, herein a nanocrystal-based biomimetic formulation with a sandwich structure is developed. As the core, flake shaped nanocrystals (NCs) with high loading of the hydrophobic drug hydroxycamptothecin (HCPT) are synthesized via a mild nanoprecipitation process by exploring the template effect of serum albumin. Meanwhile, the camouflaged cancer cell membrane (CM) composed of plentiful membrane proteins endows the NCs with homotypic targeting capacity at tumor sites. In addition, the photosensitizer indocyanine green sandwiched between NCs and CM not only converts near infrared light to heat for photothermal treatment but also improves the dissolution of HCPT NCs for chemotherapy. These features corporately achieve the orchestration of chemo-photothermal combination therapy and completely inhibit tumor growth with few adverse effects, showing promise as a new modality for the utilization of hydrophobic drugs to treat cancer.

Abstract
The treatment of metastatic tumors is highly desirable in clinics, which has also increased the interest in the design of nanoscale drug delivery systems. Bone metastasis is one of the most common pathways in the metastasis of breast cancer, and it is also an important cause for tumor recurrence and death. The aryl boronate group, as an acid-labile linker, has been introduced into nano-assemblies in recent years. Especially, as a proteasome inhibitor anticancer drug with a boric acid group, bortezomib can facilitate the formation of pH-sensitive aryl boric acid ester linkage with the catecholic group. In this study, bortezomib-loaded micelles with bone targeting properties were constructed for the treatment of breast cancer bone metastasis. The mixed micelles employed alendronate (ALN) as the bone-targeting ligand and encapsulated bortezomib-catechol conjugates as the cargo. In vitro and in vivo studies showed that compared with free drugs or control micelles, these prodrug micelles (ALN-NP) exhibited many favorable properties such as reduced systemic toxicity and improved therapeutic effects. Therefore, ALN-NP is promising as a nanovehicle for bone-targeting delivery of chemotherapeutic drugs. Furthermore, this study offers a novel strategy combining bone targeting and aryl boronate-based pH-responsive drug release for anti-metastasis therapy.

Abstract
Initially, chemotherapy is effective for treatment of bladder cancer after transurethral resection of the bladder. However, certain patients progressively become unresponsive after multiple treatment cycles, which results from the rapid and almost complete excretion of clinically used formulations of antineoplastic agents with urinary voiding. Improving the mucoadhesiveness and penetrability of chemotherapeutic drugs are key factors in treatment of advanced bladder cancer. Here, a smart disulfide-crosslinked polypeptide nanogel of poly(l-lysine)-poly(l-phenylalanine-co-l-cystine) (PLL-P(LP-co-LC)) is developed to deliver 10-hydroxycamptothecin (HCPT) for treatment of orthotopic bladder cancer. The positively charged PLL-P(LP-co-LC) can significantly prolong the retention period and enhance the tissue permeability of HCPT within the bladder wall of rat. Moreover, the reduction-responsive polypeptide nanogel (i.e., NG/HCPT) possesses the capability to accurately and rapidly deliver HCPT in bladder cancer cells. NG/HCPT can significantly inhibit proliferation of human bladder cancer 5637 cells in vitro and enhance antitumor activity toward an orthotopic rat bladder cancer model in vivo. This work demonstrates that the smart polypeptide nanogel may function as a promising drug-delivery system for local chemotherapy of bladder cancer with unprecedented clinical benefits.

Abstract
Combination therapy with enhanced therapeutic and antimetastatic efficacy has become promising for cancer treatment. There is an urgent need to design a co-delivery system to sequentially release the drug pair at desired locations that can increase the intra-tumoral drug concentration and reduce the side effects. Inspired by virus architecture and function, herein, we developed a peptosome (PS)-based co-delivery system, PePm/PS/Curcumin (Cur), for the sequential release of the therapeutic peptide Pe and chemodrug Cur. PS was formed by the self-assembly of amphiphilic α-lactalbumin peptides obtained from enzymatic partial hydrolysis. Then, PS was self-cross-linked with disulfide bonds utilizing their endogenous thiol groups. The system is responsive to multiple tumor microenvironments and releases the drugs at specific tumor locations. First, after PS accumulation in tumor tissue via the EPR effect, the linkage peptide Pm in PS can be cleaved by matrix metalloproteinases (MMP) enzymatic hydrolysis. Pe can stay on the cell surface and antagonize the ErbB-2 receptor expression on the tumor cells. Moreover, the positively charged nature of remaining Mal-PS/Cur facilitates tumor cell internalization and induces a subsequent proton-sponge effect for lysosomal escape. Finally, Cur is released in the cytoplasm via a reduction-induced PS disassembly due to the high level of intracellular GSH. Both the in vitro and in vivo results exhibited an enhanced antitumor and antimetastatic efficacy of this system.

Abstract
This review focuses on recent investigations that used Pluronic P123 (P123) as pharmaceutical ingredients in vesicle, micelle, mixed micelle, in situ gel, tablet and emulsion. The main results from these studies show that P123 can significantly increase the stability of incorporated hydrophobic drugs with enhanced in vitro cytotoxicity and cellular uptake of anticancer drugs. Moreover, modified forms of P123 with RGD, folate or other targeted marker have shown its therapeutic potentials in various types of tumors and cancers. Furthermore, modified forms of P123 alone and/or mixed with other copolymers have less toxic effects and more tumor-specific delivery of anticancer drugs. They are promising materials as a nanoplatform for the drug delivery. Finally, the future perspectives of the field are briefly discussed.

Abstract
Bortezomib (BTZ) is the first proteasome inhibitor approved by the US-FDA is majorly used for the treatment of newly diagnosed and relapsed multiple myeloma including mantle cell lymphoma. BTZ is hydrophobic in nature and is a major cause for its minimal presence as marketed formulations. The present study reports the design, development and characterization of dendrimer based formulation for the improved solubility and effectivity of bortezomib. The study also equally focuses on the mechanistic elucidation of solubilization by two types of dendrimers i.e. fourth generation of poly (amidoamine) dendrimers (G4-PAMAM-NH2) and fifth generation of poly (propylene) imine dendrimers (G5-PPI-NH2). It was observed that aqueous solubility of BTZ was concentration and pH dependent. At 2mM G5-PPI-NH2 concentration, the fold increase in bortezomib solubility was 1152.63 times in water, while approximately 3426.69 folds increase in solubility was observed at pH10.0, respectively (p<0.05). The solubility of the drug was increased to a greater extent with G5-PPI-NH2 dendrimers because it has more hydrophobic interior than G4-PAMAM-NH2 dendrimers. The release of BTZ from G5-PPI-NH2 complex was comparatively slower than G4-PAMAM-NH2. The thermodynamic treatment of data proved that dendrimer drug complexes were stable at all pH with values of ΔG always negative. The experimental findings were also proven by molecular simulation studies and by calculating RMSD and intermolecular hydrogen bonding through Schrodinger software. It was concluded that PPI dendrimers were able to solubilize the drug more effectively than PAMAM dendrimers through electrostatic interactions.

Abstract
Hepatocellular carcinoma (HCC) is the most common primary liver cancer with high morbidity and mortality worldwide. Chemotherapy is recommended to patients with intermediate or advanced stage cancer. However, the conventional chemotherapy yields low desired response rates due to multidrug resistance, fast clearance rate, nonspecific delivery, severe side effects, low drug concentration in cancer cells, and so on. Nanoparticle-mediated targeted drug delivery system can surmount the aforementioned obstacles through enhanced permeability and retention effect and active targeting as a novel approach of therapeutics for HCC in recent years. The active targeting is triggered by ligands on the delivery system, which recognize with and internalize into hepatoma cells with high specificity and efficiency. This review focuses on the latest targeted delivery systems for HCC and summarizes the ligands that can enhance the capacity of active targeting, to provide some insight into future research in nanomedicine for HCC.

Abstract
The instability of PEGylated polylactide micelles is a challenge for drug delivery. Stereocomplex interaction between racemic polylactide chains with different configurations provides an effective strategy to enhance the stability of micelles as the nanocarriers of drugs. In this work, a stereocomplex micelle (SCM) self-assembled from the amphiphilic triblock copolymers comprising poly(ethylene glycol) (PEG), and dextrorotatory and levorotatory polylactides (PDLA and PLLA) was applied for efficient drug delivery. The spherical SCM showed the smallest scale and the lowest critical micelle concentration (CMC) than the micelles with single components attributed to the stereocomplex interaction between PDLA and PLLA. 10-Hydroxycamptothecin (HCPT) as a model antitumor drug was loaded into micelles. Compared with the loading micelles from individual PDLA and PLLA, the HCPT-loaded SCM exhibited the highest drug loading efficiency (DLE) and the slowest drug release in phosphate-buffered saline (PBS) at pH 7.4, indicating its enhanced stability in circulation. More fascinatingly, the laden SCM was demonstrated to have the highest cellular uptake of HCPT and suppress malignant cells most effectively in comparison to the HCPT-loaded micelles from single copolymer. In summary, the stereocomplex-enhanced PLA⁻PEG⁻PLA micelle may be promising for optimized drug delivery in the clinic.

Abstract
Recently discovered intratumoral diffusion resistance, together with poor solubility and nontargeted distribution of chemotherapeutic drugs, has significantly impaired the performance of cancer treatments. By developing a well-designed droplet-confined/cryodesiccation-driven crystallization approach, we herein report the successful preparation of nanocrystallites of insoluble chemotherapeutic drug paclitaxel (PTX) in forms of nanodots (NDs, ≈10 nm) and nanoparticles (NPs, ≈70 nm) with considerably high drug loading capacity. Superficially coated Pluronic F127 is demonstrated to endow the both PTX nanocrystallites with excellent water solubility and prevent undesired phagocyte uptake. Further decoration with tumor-penetrating peptide iRGD, as expected, indiscriminatively facilitates tumor cell uptake in traditional monolayer cell culture model. On the contrary, distinctly enhanced performances in inward penetration and ensuing elimination of 3D multicellular tumor spheroids are achieved by iRGD-NDs rather than iRGD-NPs, revealing the significant influence of particle size variation in nanoscale. In vivo experiments verify that, although efficient tumor enrichment is achieved by all nanocrystallites, only the iRGD-grafted nanocrystallites of ultranano size realize thorough intratumoral delivery and reach cancer stem cells, which are concealed inside the tumor core. Consequently, much strengthened restriction on progress and metastasis of orthotopic 4T1 mammary adenocarcinoma is achieved in murine model, in sharp contrast to commercial PTX formulation Taxol.

Abstract
Basal-like triple negative breast cancer (TNBC) has received particular clinical interest due to its high frequency, poor baseline prognosis and lack of effective clinical therapy. Bortezomib, which was the first proteasome inhibitor approved for the treatment of multiple myeloma, has been proven to be worth investigating for this subtype of breast cancer. In our study, the amphiphilic copolymer poly(ethylene glycol)-block-poly(d,l-lactide) (PEG-b-PLA) was utilized as an excellent delivery carrier of bortezomib (BTZ) to overcome its clinical limitations including low water solubility and unstable properties. Bortezomib encapsulated nanoparticles (NPBTZ) can efficiently deliver the drug into both CSCs (cancer stem cells) and non-CSCs, resulting in proliferation inhibition and apoptosis induction. Remarkably, NPBTZ can more effectively affect the stemness of CSCs compared with free BTZ. Administration of this drug delivery system can markedly prolong the bortezomib circulation half-life and augment the enrichment of drugs in tumor tissue, then enhance the suppression of tumor growth, suggesting the therapeutic promise of NPBTZ delivery in basal-like TNBC therapy.

Abstract
We present a dialysis technique to prepare the 10-hydroxycamptothecin (HCPT)-loaded nanoparticles (NPs) using methoxypolyethylene glycol-poly(D,L-lactide) (PEG-b-PLA) and PLA, respectively. Both HCPT-loaded PEG-b-PLA NPs and HCPT-loaded PLA NPs were characterized by differential scanning calorimetry (DSC), dynamic light scattering (DLS), transmission electron microscopy (TEM), scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM). The results showed that the HCPT-loaded PEG-b-PLA NPs and HCPT-loaded PLA NPs presented a hydrodynamic particle size of 120.1 and 226.8 nm, with a polydispersity index of 0.057 and 0.207, a zeta potential of -31.2 and -45.7 mV, drug encapsulation efficiency of 44.52% and 44.94%, and drug-loaded content of 7.42% and 7.49%, respectively. The HCPT-loaded PEG-b-PLA NPs presented faster drug release rate compared to the HCPT-loaded PLA NPs. The HCPT-loaded PEG-b-PLA NPs presented higher cytotoxicity than the HCPT-loaded PLA NPs. These results suggested that the HCPT-loaded PEG-b-PLA NPs presented better characteristics for drug delivery compared to HCPT-loaded PLA NPs.

Active radar guides missile to its target: receptor-based targeted treatment of hepatocellular carcinoma by nanoparticulate systems. Tumour Biol 2014; 36:55-67. [PMID: 25424700 DOI: 10.1007/s13277-014-2855-3] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2014] [Accepted: 11/13/2014] [Indexed: 02/07/2023] Open
Abstract
Patients with hepatocellular carcinoma (HCC) usually present at advanced stages and do not benefit from surgical resection, so drug therapy should deserve a prominent place in unresectable HCC treatment. But chemotherapy agents, such as doxorubicin, cisplatin, and paclitaxel, frequently encounter important problems such as low specificity and non-selective biodistribution. Recently, the development of nanotechnology led to significant breakthroughs to overcome these problems. Decorating the surfaces of nanoparticulate-based drug carriers with homing devices has demonstrated its potential in concentrating chemotherapy agents specifically to HCC cells. In this paper, we reviewed the current status of active targeting strategies for nanoparticulate systems based on various receptors such as asialoglycoprotein receptor, transferrin receptor, epidermal growth factor receptor, folate receptor, integrin, and CD44, which are abundantly expressed on the surfaces of hepatocytes or liver cancer cells. Furthermore, we pointed out their merits and defects and provided theoretical references for further research.

Abstract
As an intrinsic characteristic of many anticancer drugs, low solubility in physiological conditions limits the usage of these active ingredients in clinics. To overcome this bottleneck, we attempt to design and construct a high-performance magnetic-targeted delivery system based on uniform iron oxide hollow spheres. Via a facile one-pot solvothermal route, well-defined iron oxide hollow spheres were prepared with inexpensive inhesion. Compared with previously reported mesoporous Fe3O4 nanoparticles, our iron oxide hollow spheres have a larger void space giving the structures a higher storage capacity for guest molecules. In our present work, camptothecin (CPT) was selected as a model insoluble anticancer drug to confirm the efficiency of drug-loading and chemotherapy in vitro. Detailed anticancer efficacy was further investigated by using MTT assays and microscope imaging methods, indicating that these iron oxide hollow spheres are promising for insoluble drug delivery.

Abstract
Nanoparticles composed of galactosylated chitosan oligosaccharide (Gal-CSO) and adenosine triphosphate (ATP) were prepared for hepatocellular carcinoma cell-specific uptake, and the characteristics of Gal-CSO/ATP nanoparticles were evaluated. CSO/ATP nanoparticles were prepared as a control. The average diameter and zeta potential of Gal-CSO/ATP nanoparticles were 51.03 ± 3.26 nm and 30.50 ± 1.25 mV, respectively, suggesting suitable properties for a drug delivery system. Subsequently, the cytotoxicity of Gal-CSO/ATP nanoparticles were examined by the methyl tetrazolium (MTT) assay, and the half maximal inhibitory concentration (IC50) values were calculated with HepG2 (human hepatocellular carcinoma cell line) cells. The results showed that the cytotoxic effect of nanoparticles on HepG2 cells was low. In the meantime, it was also found that the Gal-CSO/ATP nanoparticles could be uptaken by HepG2 cells, due to expression of the asialoglycoprotein receptor (ASGP-R) on their surfaces. The presented results indicate that the Gal-CSO nanoparticles might be very attractive to be used as an intracellular drug delivery carrier for hepatocellular carcinoma cell targeting, thus warranting further in vivo or clinical investigations.

Abstract
INTRODUCTION The livertaxis of glycyrrhizic acid-conjugated bovine serum albumin (GL-BSA) has been reported in the literature. Now, in this paper, we describe a novel type of drug-targeted delivery system containing 10-hydroxycamptothecin (HCPT) with liver tumor targeting. METHODS First, GL was coupled to BSA then HCPT was encapsulated in GL-BSA by high-pressure homogenization emulsification. In the experimental design, the influencing variables on particle size and drug loading efficiency were determined to be BSA concentration, volume ratio of water to organic phase, and speed and speed duration of homogenization as well as homogenization pressure and the number of times homogenized at certain pressures. Particle size plays an important role in screening optimal conditions of nanoparticles preparation. Characteristics of 10-hydroxycamptothecin-loaded glycyrrhizic acid-conjugated bovine serum albumin nanoparticles (GL-BSA-HCPT-NPs), such as the drug encapsulation efficiency, drug loading efficiency, and GL-BSA content were studied. In addition, the morphology of the nanoparticles (NPs) and weight loss rate were determined and Fourier transform infrared spectroscopy, X-ray diffraction spectroscopy, and thermal analysis performed. RESULTS The average particle size of the sample NPs prepared under optimal conditions was 157.5 nm and the zeta potential was -22.51 ± 0.78 mV; the drug encapsulation efficiency and drug loading efficiency were 93.7% and 10.9%, respectively. The amount of GL coupling to BSA was 98.26 μg/mg. Through physical property study of the samples, we determined that the HCPT had been successfully wrapped in GL-BSA. In vitro drug-release study showed that the nanoparticles could release the drug slowly and continuously. Hemolysis testing showed the safety of GL-BSA as a novel drug delivery system. The targeting properties of GL-BSA-HCPT-NPs were studied in an in vitro cell uptake study and cell proliferation assay. Cells incubated with GL-BSA-HCPT-NPs and labeled with fluorescein isothiocyanate showed more extensive fluorescence spots and stronger fluorescence intensity than samples without GL conjugation. MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay was used to determine the inhibitory rate of the samples. It was found that the inhibitory rate of GL-BSA-HCPT-NPs develops as concentration rises. Further, the inhibitory rate of GL-BSA-HCPT-NPs was higher at the same concentration and had a lower half maximal inhibitory concentration value than the other samples. The half maximal inhibitory concentration values of GL-BSA-HCPT-NPs, BSA-HCPT-NPs, and HCPT sodium were 0.78 ± 0.015, 1.62 ± 0.039, and 7.93 ± 0.255 μg/mL, respectively. CONCLUSION The results of this study show GL-BSA-HCPT to be a promising new vehicle for hepatocellular carcinoma-targeting therapy.

Abstract
While chitosan (CS) has been researched widely as a non-viral vector, its usefulness has been limited by its low cell specificity and transfection efficiency. Therefore, we successfully synthesized galactosylated chitosan (GC) and complexed it with an enhanced green fluorescent protein plasmid (pIRES-EGFP) for transfection into cultured H22 cells (murine hepatic cancer cell line) using various GC/EGFP (N/P) charge ratios. Maximal gene transfection rates detected by flow cytometry occurred at an N/P ratio 5:1. Compared with those of lipofectin/EGFP and naked pIRES-EGFP, GC/EGFP complexes show a very efficient cell-selective transfection to hepatocytes. The MTT assay detected relatively low cytotoxicity in cells transfected with GC. A recombinant plasmid granulocyte-macrophage colony-stimulating factor (GM-SCF) and interleukin (IL) 21 (pIRES/GM-CSF-IL21) was successfully constructed and GC/GM-CSF-IL21 nanoparticles (average diameter, 82.1 nm) were administered via the tail vein of mice with liver metastasis of colon cancer model, for 5 consecutive days. The GC/GM-CSF-IL21 nanoparticles exhibited hepatocyte and passive tumor specificity, increased therapeutic efficacy compared to control groups, promoted leukocytes to aggregate in tumor tissues, and activated the cytotoxicity of natural killer (NK) cells and cytolytic T lymphocyte (CTL). Our results indicate that GC can be used in gene therapy to improve transfection efficiency and can be used as an immunological stimulant in vivo.
