Abstract
Polymer-based nanoparticles have proven to be viable carriers of therapeutic agents. In this study, we have developed nanoparticles (NPs) from polypeptide-polyethylene glycol based triblock and diblock copolymers. The synthesized block copolymers poly(ethylene glycol)-b-poly(glutamic acid)-b-poly(ethylene glycol) (GEG) and poly(ethylene glycol)-b-poly(glutamic acid) (EG) conjugated with folic acid for targeting specificity (EGFA) have been used to encapsulate methotrexate (MTX) to form M-GEG and M-EGFA NPs aimed at passive and active targeting of cervical carcinoma. In-vitro SRB cytotoxicity and hemolysis assays revealed that these NPs were cytocompatible to healthy human cells and hemocompatible to human RBCs. Cellular uptake by FACS demonstrated their prompt internalization by human cervical carcinoma (HeLa) cells and points toward an apoptotic mechanism of cell kill as confirmed by AO/EB staining as well as histological analysis of explanted HeLa tumors. Pharmacokinetics and biodistribution studies were performed in New Zealand albino rabbits and HeLa xenografted Athymic mice models, respectively, by radiolabeling these NPs with 99mTc. Passive tumor accumulation and active targeting of MTX-loaded polymeric nanoparticles to folate expressing cells were confirmed by intravenous administration of these 99mTc-labeled M-GEG and M-EGFA NPs in HeLa tumor bearing nude mice and clearly visualized by whole-body gamma-SPECT images of these mice. Survival studies of these xenografted mice established the antiproliferative effect of these MTX-loaded NPs while corroborating the targeting effect of folic acid. These studies proved that the M-GEG NPs and M-EGFA NPs could be effective alternatives to conventional chemotherapy along with simultaneous diagnostic abilities and thus potentially viable theranostic options for human cervical carcinoma.

Abstract
Nanogels (NGs) are currently under extensive investigation due to their unique properties, such as small particle size, high encapsulation efficiency and protection of active agents from degradation, which make them ideal candidates as drug delivery systems (DDS). Stimuli-responsive NGs are cross-linked nanoparticles (NPs), composed of polymers, natural, synthetic, or a combination thereof that can swell by absorption (uptake) of large amounts of solvent, but not dissolve due to the constituent structure of the polymeric network. NGs can undergo change from a polymeric solution (swell form) to a hard particle (collapsed form) in response to (i) physical stimuli such as temperature, ionic strength, magnetic or electric fields; (ii) chemical stimuli such as pH, ions, specific molecules or (iii) biochemical stimuli such as enzymatic substrates or affinity ligands. The interest in NGs comes from their multi-stimuli nature involving reversible phase transitions in response to changes in the external media in a faster way than macroscopic gels or hydrogels due to their nanometric size. NGs have a porous structure able to encapsulate small molecules such as drugs and genes, then releasing them by changing their volume when external stimuli are applied.

Abstract
The combination of nanotechnology and medicine will be the next generation of vehicles for targeted drug delivery. Carboxymethyl chitosan loaded with the anticancer drug C-phycocyanin and the CD59-specific ligand peptide for cancer cell targeting were used to create C-phycocyanin/carboxymethyl chitosan-CD59-specific ligand peptide nanoparticles using the ionic-gelation method. Optimal synthesis conditions, selected by response surface methodology, comprised the ratio carboxymethyl chitosan:C-phycocyanin = 3:1, and carboxymethyl chitosan and CaCl2 concentrations of 2.0 and 1.0 mg/mL, respectively. The resulting nanoparticles were spherical, with diameters of approximately 200 nm; the entrapment efficient was about 65%; and the drug loading was about 20%. The release of C-phycocyanin from C-phycocyanin/carboxymethyl chitosan nanoparticles was pH sensitive and had a sustainable effect in vitro. Guided by the CD59-specific ligand peptide, the nanoparticles efficiently targeted the surface of HeLa cells and had an obvious inhibitory effect on HeLa cell proliferation as determined by methyl thiazolyl tetrazolium assays. The nanoparticles were hemocompatible and induced apoptosis by upregulation of cleaved caspase-3 and cleaved polyADP-ribose polymerase proteins, and downregulation of Bcl-2 proteins. Our study provides a novel approach to the research and development of marine drugs, and support for targeted therapy using anticancer drugs.

Abstract
A tumor-targeting drug delivery system consists of a tumor recognition moiety and a directly linked cytotoxic agent or an agent attached to a water-soluble synthetic polymer carrier through a suitable linker. Conjugation of a drug with a polymer carrier can change its solubility, toxicity, biodistribution, blood clearance and therapeutic specificity. Increased therapeutic specificity of a polymer drug can be achieved by the attachment of a targeting moiety (e.g. a lectin, protein, antibody, or peptide) that specifically interacts with receptors on the target cells. A large number of tumor-specific peptides were described in recent years. After a short introduction, some important examples of peptide-targeted conjugates will be described and discussed.

Acta Biomater 2016; 40:243-253. [PMID: 27063495 DOI: 10.1016/j.actbio.2016.04.007] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/20/2015] [Revised: 03/28/2016] [Accepted: 04/06/2016] [Indexed: 12/22/2022]
Abstract
UNLABELLED The linear, Y-shaped, and linear-dendritic block copolymers of methoxy poly(ethylene glycol)-block-polyamidoamine-block-poly(l-glutamic acid) (MPEG-b-PAMAM-b-PGA) with one, two, four, and eight PGA arms but similar MPEG/PGA weight ratios (W/W) (named as P1PA, P2PA, P4PA and P8PA, respectively) were synthesized and comparatively investigated for doxorubicin hydrochloride (DOX) delivery. All the obtained block copolymers were highly biocompatible and could efficiently load DOX into nanoparticles (NPs) through electrostatic interaction. The NPs formed by linear (P1PA) or Y-shaped (P2PA) block copolymers and DOX were spherically shaped with smaller sizes, while the NPs formed from linear-dendritic block copolymers (P4PA and P8PA) were irregular in shape and larger in size. The P1PA/DOX and P2PA/DOX NPs exhibited better DOX protection and slower DOX release profile. However, cell cytotoxicity assays indicated that all the DOX-loaded NPs exhibited similar cytotoxicities with free DOX, indicating effective DOX release after cellular uptake. The NPs from linear and Y-shaped block copolymers greatly extended the blood circulation time, and displayed more accumulation in tumor site and less accumulation in the liver and kidney compared with the linear-dendritic counterparts. In addition, the P1PA/DOX and P2PA/DOX NPs also exhibited higher anti-tumor efficacy and less toxicity than the other DOX formulations. All these results indicated that the linear and Y-shaped MPEG-b-PAMAM-b-PGA block copolymers displayed better DOX delivery ability in anti-tumor treatment than the linear-dendritic copolymers. STATEMENT OF SIGNIFICANCE Polymeric NPs derived from block copolymers have emerged as effective vehicles for drug delivery. However, the majority of the researches in this field have involved simple linear block copolymers and there are very few comparative studies on the self-assembly, in vitro, and in vivo drug delivery by the block copolymers with similar composition but different architectures. In this study, a series of linear, Y-shaped, and linear-dendritic polypeptide-based block copolymers were prepared and thoroughly investigated for DOX delivery. These block polymers loaded DOX into NPs with different sizes and morphologies, and exhibited different anti-tumor capabilities both in vitro and in vivo. The results indicated that the architecture of the block copolymers played an important role in their drug delivery behaviors.

Abstract
Polymeric prodrugs formed by the conjugation of drugs onto polymers have shown great promise in cancer therapy because of the enhancement of water solubility, elimination of premature drug release, and the improvement of pharmacokinetics. To integrate the two advantages of upregulated stability during circulation and selective release of drug in cancer cells, a pH and reduction dual-sensitive prodrug nanogel (CLP) was synthesized via a simple one step "click chemistry". CLP was spherically shaped with a uniform diameter of 60.6 ± 13.7 nm and exhibited great stability in size against large volume dilution, high salt concentration, and long-time incubation in phosphate-buffered saline. Owing to the presence of hydrazone-bonded doxorubicin (DOX) and disulfide cross-linker, CLP released minimal amount (7.8%) of drug under normal physiological pH (i.e., 7.4) condition. But it released 85.5% of the loaded DOX at endosomal pH (i.e., 5.5) plus the presence of 5.0 mM GSH in 120 h. CLP could be effectively internalized by tumor cells and subsequently release DOX in the intracellular environment, resulting in effective proliferation inhibition of HeLa and MCF-7 cells. Furthermore, compared with free DOX and non-cross-linked prodrug micelle (NCLP), CLP accumulated more in tumor site but less in the normal organs, so that CLP performed the enhanced antitumor efficiency and reduced side-toxicities toward the MCF-7 human breast cancer xenograft nude mouse model. With convenient fabrication, favorable stability, controlled release properties, optimized biodistribution, and enhanced suppression of tumor growth, CLP held great potential for optimal antitumor therapy.

A microporous covalent triazine polymer (CTP) network with a high surface area was synthesized via the Friedel-Crafts reaction and employed as a potential transport system for drug delivery and controlled release. The CTP was transformed to the nanoscale region by intense ultrasonication followed by filtration to yield nanoscale CTP (NCTP). This product showed excellent dispersibility in physiological solution while maintaining its chemical structure and porosity. An anticancer drug, doxorubicin (DOX), was loaded onto the NCTP through hydrophobic and π-π interactions, and its release was controlled at pH 4.8 and 7.4. The NCTP showed no toxicity toward cancer or normal cells, but the NCTP-DOX complex showed high efficacy against both types of cells in vitro. In-vitro cell imaging revealed that NCTP is a potential material for bioimaging. The potency of NCTP on cellular senescence was confirmed by the expression of senescence associated marker proteins p53 and p21. These results suggest that NCTP can be used as a new platform for drug delivery and imaging with potential applications in diagnosis and therapy.

Abstract
Targeting cancer cells using integrin receptor is one of the promising targeting strategies in drug delivery. In this study, we conjugated an integrin-binding ligand (GGRGDSK) peptide to chitosan oligosaccharide (COS) using sulfo-SMCC as a bifunctional linker to afford COS-SMCC-GGRGDSK. The conjugated polymer was characterized by FT-IR, (1)H NMR, (13)C NMR, and SEM. COS-SMCC-GGRGDSK did not show cytotoxicity up to a concentration of 1mg/mL in the human leukemia cell line (CCRF-CEM). The conjugate was evaluated for its ability to enhance the cellular uptake of a cell-impermeable cargo (e.g., F'-G(pY)EEI phosphopeptide) in CCRF-CEM, and human ovarian carcinoma (SK-OV-3) cancer cell lines. Additionally, RGD modified and unmodified COS polymers were used to prepare nanoparticles by ionic gelation and showed particle size ranging from 187 to 338nm, and zeta potential of 12.2-18.3mV using dynamic light scattering. The efficiency of COS-NPs and COS-SMCC-RGDSK NPs was assayed for translocation of two synthetic cytotoxic agents ((2-(2-aminoethylamino)-4-(4-chlorophenyl)-6-(1H-indol-3-yl) nicotinonitrile (ACIN), and 2-(2-aminoethylamino)-6-(1H-indol-3-yl)-4-(4-methoxyphenyl)-nicotinonitrile (AMIN)) into CCRF-CEM and human prostate (DU-145) cancer cell lines. The results showed a dramatic reduction in the cell viability on their treatment with RGD targeted COS NPs in comparison to paclitaxel (PTX), free drug, and drug-loaded COS NPs.

Abstract
The biopharmaceutical properties of supramolecular vesicular aggregates (SVAs) were characterized with regard to their physicochemical features and compared with cationic liposomes (CLs). Neutral and cationic SVAs were synthesized using two different copolymers of poly(aspartyl hydrazide) by thin-layer evaporation and extrusion techniques. Both copolymers were self-assembled in pre-formulated liposomes and formed neutral and cationic SVAs. Gemcitabine hydrochloride (GEM) was used as an anticancer drug and loaded by a pH gradient remote loading procedure, which significantly increased drug loading inside the SVAs. The resulting average size of the SVAs was 100 nm. The anticancer activity of GEM-loaded neutral and cationic SVAs was tested in human alveolar basal epithelial (A549) and colorectal cancer (CaCo-2) cells. GEM-loaded cationic SVAs increased the anticancer activity in A549 and CaCo-2 cells relative to free drug, neutral SVAs, and CLs. In vivo biodistribution in Wistar rats showed that cationic SVAs accumulate at higher concentrations in lung tissue than neutral SVAs and CLs. Cationic SVAs may therefore serve as an innovative future therapy for pulmonary carcinoma.

Abstract
Tumor microenvironment-responsive nano drug delivery vehicles are gaining mounting attention in the field of biomedical sciences. The hypoxic response of the tumorous cells due to very low partial pressure of oxygen (some time less than 2.5 mm of Hg) in the tumor tissues makes hypoxia-responsive drug delivery system as the more appealing in cancer chemotherapy. Based on these considerations, we synthesized hypoxia-responsive polymeric materials methoxy poly (ethylene glycol)-block-poly (glutamic acid)-graft-6-(2-nitroimidazole) hexyl amine (mPEG-b-PLG-g-NID) by conjugation of the hydrophobic nitro imidazole derivative (NID)[6-(2-nitroimidazole) hexyl amine] with the pendant carboxylic group of poly (ethylene glycol)-block-poly (L-glutamic acid)(mPEG-b-PLG). The structure and degree of substitution were confirmed by proton NMR, FTIR, and UV-Vis spectroscopy. The degree of substitution was found to enhance with the increase in NID to polymer ratio. The hypoxia response of the material was evaluated by UV-Vis spectroscopy and zeta potential measurements. Doxorubicin was hydrophobically encapsulated in the micellar core of the hypoxia-responsive nanoparticles. The drug-loaded micelles showed faster release in hypoxic condition as compared to normoxic conditions. Moreover, the developed polymeric system was found non-toxic to MCF-7 cell line, thus suggesting its biocompatibility and suitability as drug delivery device.

Abstract
An amphiphilic anionic polypeptide, methoxypolyethylene glycol-poly (glutamic acid) (mPEG-PGA), was synthesized, characterized and evaluated as a nanocarrier for the cationic anticancer drug doxorubicin hydrochloride (DOX·HCl). The complex self-assembled into nanorods in aqueous solutions via electrostatic interactions and exhibited a superior drug loading content (50.8%) and drug loading efficiency (90.2%). The average major axis of the drug-loaded nanorods was approximately 300nm, as determined by transmission electron microscopy. An in vitro release assay showed that drug-loaded nanorods exhibited pH-sensitivity and sustained release. Haemolysis assays demonstrated that the polypeptide was haemocompatible, and the polypeptide drug carrier significantly reduced the haemolysis ratio of DOX·HCl. The pharmacokinetics study showed that DOX-loaded nanorods significantly prolonged the resident time in blood. An in vitro cytotoxicity study and cellular uptake assays demonstrated that the DOX-loaded nanorods resulted in higher cell proliferation inhibition and a higher level of tumour cell uptake in A549 cells than with free DOX·HCl. The prolonged circulation and enhanced antitumor efficacy of DOX-loaded nanorods shows promise for efficient cancer chemotherapy.

Abstract
Conjugates of anthracyclines are a new possibility for anticancer agent delivery, which seems to be a very promising alternative to the currently used cancer treatment strategies. In our study, we investigated the ability of a doxorubicin-transferrin (DOX-TRF) conjugate to induce cell death in two solid tumor cell lines: non-small cell lung cancer (A549) and hepatocellular liver carcinoma (HepG2). The observed effects of the DOX-TRF conjugate on these cell cultures were compared with those of free doxorubicin (DOX), a widely used antineoplastic therapeutic agent. Our results provided direct evidence that the investigated conjugate is considerably more cytotoxic to the examined human cancer cell lines than is DOX alone. Moreover, we confirmed that the antitumor efficacy of DOX-TRF conjugate is related to its apoptosis-inducing ability, which was shown during measurements of typical features of programmed cell death. In solid tumor cell lines, the DOX-TRF conjugate induced changes in cellular morphology, mitochondrial membrane potential and caspases-3 and -9 activities. Furthermore, all of the analyzed hallmarks of apoptosis were confirmed by the oligonucleosomal DNA fragmentation assay and by a real-time PCR quantitative study, which displayed the superiority of the conjugate-induced programmed cell death over free drug-triggered cell death.

Co-delivery of docetaxel and chloroquine via PEO-PPO-PCL/TPGS micelles for overcoming multidrug resistance. Int J Pharm 2015; 495:932-9. [PMID: 26456262 DOI: 10.1016/j.ijpharm.2015.10.009] [Citation(s) in RCA: 59] [Impact Index Per Article: 6.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2015] [Revised: 09/18/2015] [Accepted: 10/03/2015] [Indexed: 01/19/2023]
Abstract
The combination of two or more drug is a promising strategy to suppress the multidrug resistance (MDR) through different action mechanisms. Co-delivery drugs via polymeric micelle can minimize the amount of each drug and reduce toxic side effects. Here we co-encapsulate anticancer drug docetaxel (DTX) and autophagy inhibitor chloroquine (CQ) in complex micelles based on poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ϵ-caprolactone) (PEO-PPO-PCL) and D-α-tocopheryl poly(ethylene glycol) (TPGS) for enhancing anticancer effects. Two series copolymer with different length of hydrophobic chain were synthesized (PEO68-PPO34-PCL18 and PEO68-PPO34-PCL36) in our lab. The dual-drug micelles possessed nanosize and sustained release profile in vitro. Drug-loaded micelles have low hemolysis rate (<5%), indicating that they are safe for use in vivo. Studies on cellular uptake demonstrate that the micelles can effectively accumulate in cancer cells. Furthermore, in vitro cytotoxicity with different DTX/CQ mass ratio are studied and the sample with a DTX/CQ ratio of 0.8/0.2 is found to have the strongest synergism effect. The co-delivery micelles have obviously higher therapeutic effects against MCF-7 and MCF-7/ADR cells than either free drug or individually DTX-loaded micelles. The IC50 values of DTX/CQ-loaded PEO68-PPO34-PCL18/TPGS and PEO68-PPO34-PCL36/TPGS micelles are 134.16 and 194.74 fold smaller than that of free DTX after 48 h treatment with MCF-7/ADR cells, respectively. Therefore, the as-prepared co-delivery of DTX and CQ based on PEO-PPO-PCL/TPGS micelles can provide a promising combined therapeutic strategy for enhanced antitumor therapy.

Abstract
Multi-drug therapy is described as a simultaneous or sequential administration of two or more drugs with similar or different mechanisms of action and is recognized as a more efficient solution to combat successfully, various ailments. Polymeric micelles (PMs) are self-assemblies of block copolymers providing numerous opportunities for drug delivery. To date various micellar formulations were studied for delivery of drugs, nutraceuticals and genes; a few of them are in clinical trials. It was observed that there is an immense need for the development of PMs embedding multiple therapeutic agents to combat various ailments, including cancers, HIV/AIDS, malaria, multiple sclerosis, hypertension, infectious diseases, cardiovascular and metabolic diseases, immune disorders and many psychiatric disorders. Several combinations of drug-drug, drug-nutraceutical, drug-gene and drug-siRNA explored to date are detailed in this review, with a special emphasis on their potential and future perspectives. A summary of various preparation methods, characterization techniques and applications of PMs are also provided. This review presents a holistic approach on multi-drug delivery using micellar carriers and emphasizes on the development of therapeutic hybrids embedding novel combinations for safer and effective therapy.

Abstract
Multifunctional nanocomposites hold great potential to integrate therapeutic and diagnostic functions into a single nanoscale structure. In this paper, we prepared the MTX-PEG-CS-IONPs-Cy5.5 nanocomposites by functionalizing the surface of chitosan-decorated iron oxide nanoparticles (CS-IONPs) with polyethylene glycolated methotraxate (MTX-PEG) and near-infrared fluorescent cyanin dye (Cy5.5). A clinically useful PEGylated anticancer prodrug, MTX-PEG, was also developed as a tumor cell-specific targeting ligand for self-targeted cancer treatment. In such nanocomposites, the advantage was that the orthogonally functionalized, self-targeted MTX-PEG-CS-IONPs-Cy5.5 can synergistically combine an early phase selective tumor-targeting efficacy with a late-phase cancer-killing effect, which was also confirmed by dual model (magnetic resonance and fluorescence) imaging. Furthermore, with the aids of the folate (FA) receptor-mediated endocytosis (able to turn cellular uptake "off" in normal cells and "on" in cancer cells) and pH/intracellular protease-mediated hydrolyzing peptide bonds (able to turn drug release "off" in systemic circulation and "on" inside endo/lysosomes), the MTX-PEG-CS-IONPs-Cy5.5 could deliver MTX to FA receptors-overexpressed cancer cells, showing the improved anticancer activity with the reduced side effects. Together, the MTX-PEG-CS-IONPs-Cy5.5 could act as a highly convergent, flexible, and simplified system for dual model imaging and synergistically self-targeted cancer therapy, holding great promise for versatile biomedical applications in future.

Abstract
In the present study, a gene and drug codelivery system was developed by electrostatic binding of polyethylenimine-poly(l-lysine)-poly(l-glutamic acid) (PELG), polyethylenimine (PEI), cis-aconityl-doxorubicin (CAD), and DNA. Zeta potential and drug release analysis confirmed the pH-responsive charge conversion and acid-sensitive drug release functional properties of the PELG/PEI/(DNA+CAD) system. Gel retardation assay and transfection experiment showed the codelivery system had effective DNA binding ability and good transfection efficiency on HepG2 cells. The therapeutic gene p53 was further employed to study its combinational effects with CAD. Cytotoxicity assay showed the half inhibitory concentration (IC50) of the PELG/PEI/(p53+CAD) codelivery system was lower than that of the gene or the drug delivery system. Confocal laser scanning microscopy (CLSM) showed that the drug and gene could be delivered into the cells simultaneously. A significant increase of p53 gene expression was achieved after HepG2 cells treated by PELG/PEI/(p53+CAD) codelivery system. The apoptosis experiment indicated clearly that the codelivery system could lead an effective apoptosis on tumor cells, which was beneficial for the treatment of cancer. The biodistribution and tumor accumulation of the codelivery system was explored via in vivo imaging in subcutaneous xenograft and in situ tumor models. The tumor and some major organs were excised and imaged, and the results showed that the codelivery system can accumulate efficiently in tumor for both tumor models. It can be suggested from the above results that the PELG/PEI/(DNA+CAD) codelivery system will have great potential applications in cancer therapy.

Abstract
The amphiphilic diblock copolymer composed of methoxy poly(ethylene glycol) and racemic oligoleucine was synthesized which formed into micelle with uniform size in aqueous environment. Doxorubicin (DOX) was loaded into micelle aided by noncovalent interactions with high drug loading efficiency. The DOX-loaded micelle (referred as M-DOX) demonstrated the sustained drug release in vitro and excellent antiproliferative capability toward both MG63 and Saos-2 cells. Furthermore, for both MG63 and Saos-2-xenografted BALB/c nude mouse models, M-DOX exhibited enhanced intratumoral distribution, improved antitumor efficacy, and reduced side effects compared with free DOX. Therefore, the polypeptide micelle showed a bright prospect for controlled delivery of antitumor drugs in vivo.

Abstract
The multi-modal combination therapy is proved powerful and successful to enhance the antitumor efficacy in clinics as compared with single therapy modes. In this study, the potential of combining chemotherapy with antiangiogenic therapy for the treatment of non-small-cell lung cancer is explored. Towards this aim, OEGylated carboxymethyl cellulose-(2-(2-(2-methoxyethoxy)ethoxy)methyl)oxirane (CMC-ME2MO) is prepared by treating CMC with ME2MO in the alkaline aqueous solution, and used to efficiently carry doxorubicin (DOX) with high drug-loading content (16.64%) and encapsulation efficiency (99.78%). As compared to free DOX, the resulting nanoparticles show not only the favorable stability in vitro but also the prolonged blood circulation, improved safety and tolerability, optimized biodistribution, reduced systemic toxicity, and enhanced antitumor efficacy in vivo, indicates a potential utility in cancer chemotherapy. Furthermore, the combination of the DOX-loaded polysaccharide nanoparticles and antiangiogenic drug endostar provides synergistic effects of chemotherapy and antiangiogenic therapy, which shows the highest efficiency in tumor suppression. The combination approach of the DOX-containing nanomedicine and endostar for efficient treatment of non-small-cell lung cancer is first proposed to demonstrate the synergistic therapeutic effect. This synergistic combination proves to be a promising therapeutic regimen in cancer therapy and holds great potential for clinical application.
