Int J Nanomedicine 2024; 19:7215-7236. [PMID: 39050875 PMCID: PMC11268760 DOI: 10.2147/ijn.s427144] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2023] [Accepted: 05/29/2024] [Indexed: 07/27/2024] Open
Abstract
Introduction Current therapeutic strategies, including immune checkpoint blockade (ICB), exhibit limited efficacy in treating hepatocellular carcinoma (HCC). Nanoparticles, particularly those that can accumulate specifically within tumors and be activated by sonodynamic therapy (SDT), can induce immunogenic cell death (ICD); however, ICD alone has not achieved satisfactory therapeutic effectiveness. This study investigates whether combining ICB with ICD induced by nanoparticle-mediated SDT could enhance anti-tumor immunity and inhibit HCC growth. Methods We developed an iron-based micelle nanodelivery system encapsulating the Near-Infrared Dye IR-780, which was surface-modified with a cyclic tripeptide composed of arginine-glycine-aspartic acid (cRGD). This led to the synthesis of targeted IR780@FOM-cRGD nanoparticles. These nanoparticles were specifically engineered to kill tumor cells under sonication, activate immunogenic cell death (ICD), and be used in conjunction with immune checkpoint blockade (ICB) for the treatment of hepatocellular carcinoma (HCC). Results The synthesized IR780@FOM-cRGD nanoparticles had an average diameter of 28.23±1.750 nm and a Zeta potential of -23.95±1.926. Confocal microscopy demonstrated that IR780@FOM-cRGD could target HCC cells while minimizing toxicity to healthy cells. Upon sonodynamic activation, these nanoparticles consumed significant amounts of oxygen and generated substantial reactive oxygen species (ROS), effectively killing tumor cells and inhibiting the proliferation, invasion, and migration of H22 cells. Hemolysis assays confirmed the in vivo safety of the nanoparticles, and in vivo fluorescence imaging revealed significant accumulation in tumor tissues. Mouse model experiments showed that combining ICB(which induced by Anti-PD-L1) with ICD (which induced by IR780@FOM-cRGD), could effectively activated anti-tumor immunity and suppressed tumor growth. Discussion This study highlights the potential of IR780@FOM-cRGD nanoparticles to facilitate tumor eradication and immune activation when used in conjunction with Anti-PD-L1 therapy. This combination represents a non-invasive, efficient, and targeted approach for the treatment of hepatocellular carcinoma (HCC). By integrating sonodynamic therapy with immunotherapy, this strategy promises to substantially improve the effectiveness of traditional treatments in combating HCC, offering new avenues for clinical application and therapeutic innovation.

Abstract
BACKGROUND/AIMS Colon cancer remains a life-threating disease with increasing morbidity and mortality worldwide despite the advancement in modern medical treatment. Therefore, novel and effective anti-colon cancers drugs are urgently needed. In this study, we investigated the anti-metastatic property EnDuo, a modified version of Endostar, and the underlying mechanisms. METHODS Colon cancer cells were treated with different concentrations of EnDuo (50 μg/mL, 100 μg/mL, 200 μg/mL), and Endostar (100 μg/mL) as positive control. Cell Counting Kit-8 assay was performed to test the effect of EnDuo on cell viability. A scratch wound assay and transwell assay were employed to evaluate the relocation and motility of malignant colon cells following treatment with EnDuo. Western blot analysis was used to determine inhibitory effects of EnDuo by detecting the phosphorylation level of AKT and ERK proteins, and the expression of MMP-2 and MMP-9 proteins. RESULTS Our results showed that EnDuo impedes the migration of colon cancer cells in a dose-dependent manner. At the molecular level, EnDuo induced a significant reduction in the phosphorylation of AKT and ERK proteins, and inhibited the expression of MMP-2 and MMP-9 proteins. CONCLUSIONS Collectively, these results demonstrate that EnDuo exhibits a comparable anti-metastatic effect by suppressing the migration of colon cancer cells. Possibly, EnDuo interrupts the PI3K/AKT/ERK signaling pathway to arrest cell migration. Our study provides a novel insight to the potential clinical applications of EnDuo against colon cancers in the future.

Curr Cancer Drug Targets 2020; 20:306-315.

Abstract
BACKGROUND Integrins are crucial anti-cancer therapy targets. We previously showed that tablysin-15 is an integrin antagonist with its Arg-Gly-Asp motif in a novel structural context. OBJECTIVE Here we investigated the anti-cancer effects and mechanisms of action of tablysin-15 in melanoma cells. METHODS Cell adhesion, competitive binding, cell viability, and ATP chemiluminescence assays were used to analyze the binding of tablysin-15 to αvβ3 integrin and its phenotypic effects. Wound healing, transwells, and zymography were performed to detect motility and matrix metalloproteinase- 2/-9 activities. PARP and caspase-3 cleavage were used as apoptosis assays, while LDH release and flow cytometry were used for necrosis and cell cycle analysis. The expression of mRNAs and proteins of target molecules was measured by qRT-PCR and western blotting, respectively. RESULTS Tablysin-15 dose-dependently inhibited the proliferation, migration, and invasion of M21 cells through integrin αvβ3. The proliferation inhibition caused by tablysin-15 was attributable to G0/G1 phase arrest rather than apoptosis or necrosis. Furthermore, tablysin-15 suppressed MMP-2/- 9 activities and the mRNA expression of MMP-2/-9 and COX-2 but was upregulated TIMP-1 in M21 cells. Meanwhile, tablysin-15 suppressed the expression of cyclin D1/E and CDK 2/6, the phosphorylation of FAK, Akt, and ERK, and nuclear translocation of NF-κB, while increasing the expression of the CDK inhibitor p21waf1/C1. Taken together, tablysin-15 might inhibit melanoma cell metastasis and proliferation by competing with αvβ3 integrin, thereby blocking FAK-associated signaling pathways and nuclear translocation of NF-κB. CONCLUSION Tablysin-15 has reliable anti-cancer effects against M21 melanoma cells, suggesting tablysin-15 is a promising anti-tumor drug.

Abstract
Collectively migrating tumor cells have been recently implicated in enhanced metastasis of epithelial malignancies. In oral squamous cell carcinoma (OSCC), αv integrin is a crucial mediator of multicellular clustering and collective movement in vitro; however, its contribution to metastatic spread remains to be addressed. According to the emerging therapeutic concept, dissociation of tumor clusters into single cells could significantly suppress metastasis-seeding ability of carcinomas. This study aimed to investigate the anti-OSCC potential of novel endostatin-derived polypeptide PEP06 as a cluster-dissociating therapeutic agent in vitro. Firstly, we found marked enrichment of αv integrin in collectively invading multicellular clusters in human OSCCs. Our study revealed that metastatic progression of OSCC was associated with augmented immunostaining of αv integrin in cancerous lesions. Following PEP06 treatment, cell clustering on fibronectin, migration, multicellular aggregation, anchorage-independent survival and colony formation of OSCC were significantly inhibited. Moreover, PEP06 suppressed αv integrin/FAK/Src signaling in OSCC cells. PEP06-induced loss of active Src and E-cadherin from cell–cell contacts contributed to diminished collective migration of OSCC in vitro. Overall, these results suggest that PEP06 polypeptide 30 inhibiting αv integrin/FAK/Src signaling and disrupting E-cadherin-based intercellular junctions possesses anti-metastatic potential in OSCC by acting as a cluster-dissociating therapeutic agent.

Abstract
αvβ3 integrin expressed on cancer cell surfaces is associated with important cancer hallmarks including survival and metastasis and is thus a potential anticancer drug target. Tablysin-15 contains the RGD motif and is a high-affinity αvβ3 integrin antagonist. The aim of this study was to investigate the antitumor effect and mechanism of action of tablysin-15 against αvβ3 integrin high-expressing breast cancer cell lines in vitro and in vivo. Tablysin-15 dose-dependently inhibited the proliferation, migration, and invasion of two breast cancer cell lines via the αvβ3 integrin in vitro. Proliferation inhibition was attributable to G0/G1 phase cell cycle arrest rather than apoptosis or necrosis. Furthermore, tablysin-15 downregulated the activity and mRNA expression of MMP-2/-9, VEGF, and COX-2 but upregulated TIMP-1/-2 mRNA in both cell lines. Further, tablysin-15 suppressed the expression of CDK2, CDK6, cyclin D1, and cyclin E, the phosphorylation of FAK, Akt, GSK-3β, and ERK, and the nuclear translocation of NF-κB while increasing the expression of the CDK inhibitor p21waf1/C1. Lastly, tablysin-15 provided effective antitumor protection in vivo. Thus, tablysin-15 inhibits the metastasis and proliferation of breast cancer cells through binding αvβ3 integrin and blocking FAK-associated signaling pathways as well as nuclear translocation of NF-κB.

PEP06 polypeptide 30 exerts antitumour effect in colorectal carcinoma via inhibiting epithelial-mesenchymal transition. Br J Pharmacol 2018; 175:3111-3130. [PMID: 29722931 PMCID: PMC6031886 DOI: 10.1111/bph.14352] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2018] [Revised: 04/17/2018] [Accepted: 04/20/2018] [Indexed: 12/28/2022] Open
Abstract
BACKGROUND AND PURPOSE PEP06, a polypeptide modified from endostatin, was investigated for its antitumour effects on colorectal cancer (CRC) and the possible mechanisms of this antitumour activity were examined in in vitro and in vivo models. EXPERIMENTAL APPROACH After PEP06 treatment, cell proliferation and migration assays were performed in CRC cells. Epithelial-mesenchymal transition (EMT) progression was determined by Western blotting, immunofluorescent staining and immunohistochemistry in vitro and in a residual xenograft model. MiRNAs regulated by PEP06 were identified by miRNA microarray and verified by in situ hybridization and quantitative real-time PCR. The interactions between PEP06 and integrin αvβ3 were determined with Biacore SA biochips. The cellular function of miR-146b-5p was validated by gain-of-function and loss-of-function approaches. A mouse model of lung metastasis was used to determine the effect of PEP06 on metastatic growth. KEY RESULTS PEP06 did not affect cell viability but reduced migration and EMT in SW620 and HCT116 cells. PEP06 significantly repressed the expression of miR-146b-5p in these two cell lines through binding to integrin αvβ3. MiR-146b-5p was shown to increase EMT by targeting Smad4, and the miR-146b-5p-Smad4 cascade regulated EMT in CRC. PEP06 also suppressed CRC pulmonary metastasis, increased survival of mice and hampered residual tumour growth by inhibiting EMT through down-regulating miR-146b-5p. CONCLUSIONS AND IMPLICATIONS PEP06 is a polypeptide that inhibits the growth and metastasis of colon cancer through its RGD motif binding to integrin αvβ3, thereby down-regulating miR-146b-5p to inhibit EMT in vitro and in vivo. It might have potential as a therapeutic for CRC.

Abstract
Multifunctional nanoprobes have great potential as effective radiosensitizers and drug carriers. RGD-modified gold nanorods could increase the uptake of nanoparticles via receptor-mediated endocytosis in integrin alphaV beta3-overexpressing breast cancer cells, which could enhance the effects of radiation on tumor cells, leading to further radiosensitization. The purpose of our study was to demonstrate that RGD-conjugated mesoporous silica-encapsulated gold nanorods significantly enhanced the sensitization of triple-negative breast cancer to megavoltage energy. The results indicated that RGD-conjugated mesoporous silica-encapsulated gold nanorod multifunctional nanoprobes could achieve radiosensitization in vitro and in vivo, which suggests the potential translation of this nanotechnology to clinical applications in tumor-targeting and selective therapy.

Abstract
αvβ3 integrin receptors expressed on cancer cell surfaces play a crucial role in promoting tumor angiogenesis and cancer cell metastasis. Thus, cyclic arginyl-glycyl-aspartic acid (cRGD) peptides have been explored as a αvβ3 integrin receptor-specific targeting moiety for the targeted delivery of nanoparticle-loaded therapeutics. However, our previous study showed that cyclic RGD could act as a double-edged sword that, on one hand, extended the retention of cRGD-modified solid lipid nanoparticles (RGD-SLNs) at αvβ3 integrin receptor overexpressing breast carcinoma, and yet on the other hand, decreased the amount of tumor accumulation of RGD-SLNs attributable to the greater uptake by the mononuclear phagocyte system (MPS). Therefore, we aimed to optimize the RGD-decorated nanoparticle systems for (1) inhibiting αvβ3 integrin receptor overexpressing tumor cell metastasis and (2) increasing nanoparticle accumulation to tumor site. SLNs with cRGD content ranging from 0 to 10 % mol of total polyethyleneglycol (PEG) chains were synthesized. The binding of RGD-SLNs with αvβ3 integrin receptors increased with increasing cRGD concentration on the nanoparticles. RGD-SLNs were demonstrated to inhibit MDA-MB-231 cell adhesion to fibronectin and invasion through Matrigel. In vivo whole-body fluorescence imaging revealed that 1 % cRGD on the SLNs' surface had maximum tumor accumulation with extended tumor retention among all formulations tested in an orthotopic MDA-MB-231/EGFP breast tumor model. This work has laid a foundation for further development of anticancer drug-loaded optimized cRGD nanoparticle formulations for the treatment of breast cancer metastasis.

Abstract
The major aim of the present study was to develop an integrin receptor-targeted liposomal paclitaxel (PTX) to enhance the targeting specificity and therapeutic effect of PTX on hepatocellular carcinoma (HCC) cells. The specific Arg-Gly-Asp (RGD) ligand was conjugated to 1,2-distearoylphosphatidylethanolamine-polyethylene glycol 2000 to prepare the RGD-modified liposomes (RGD-LP). Furthermore, physicochemical characteristics of RGD-LP, including particle size, ζ potential, encapsulation efficiency and in vitro PTX release, were evaluated. RGD-modified liposomes were selected as the carrier for the present study, as they exhibit good biocompatibility and are easy to modify using RGD. The cellular uptake efficacy of RGD-LP by HepG2 cells was 3.3-fold higher than that of liposomes without RGD, indicating that RGD-LP may specifically target HepG2 cells by overexpressing integrin αvβ3 receptors. The RGD modification appeared to enhance the anti-proliferative activity of LP-PTX against HepG2 cells, with the extent of anti-proliferative activity dependent on the concentration of PTX and the incubation time. Additionally, evaluation of the homing specificity and anticancer efficacy of RGD-LP on the tumor spheroids indicated that solid tumor penetration was enhanced by the modification of RGD. In agreement with these in vitro findings, in vivo investigations demonstrated that RGD-LP-PTX exhibited a greater inhibitory effect on tumor growth in HepG2-bearing mice than LP-PTX or free PTX. Thus, RGD-LPs may represent an efficient targeted PTX delivery system for the treatment of patients with HCC.

Increased tumor targeted delivery using a multistage liposome system functionalized with RGD, TAT and cleavable PEG. Int J Pharm 2014; 468:26-38. [PMID: 24709209 DOI: 10.1016/j.ijpharm.2014.04.008] [Citation(s) in RCA: 77] [Impact Index Per Article: 7.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2014] [Revised: 04/03/2014] [Accepted: 04/03/2014] [Indexed: 12/20/2022]
Abstract
Though PEGylation has been widely used to enhance the accumulation of liposomes in tumor tissues through enhanced permeability and retention (EPR) effects, it still inhibits cellular uptake and affects intracellular trafficking of carriers. Active targeting molecules displayed better cell selectivity but were shadowed by the poor tumor penetration effect. Cell penetrating peptides could increase the uptake of the carriers but were limited by their non-specificity. Dual-ligand system may possess a synergistic effect and create a more ideal drug delivery effect. Based on the above factors, we designed a multistage liposome system co-modified with RGD, TAT and cleavable PEG, which combined the advantages of PEG, specific ligand and penetrating peptide. The cleavable PEG could increase the stability and circulation time of liposomes during circulation. After the passive extravasation to tumor tissues, the previously hidden dual ligands on the liposomes were exposed in a controlled manner at the tumor site through exogenous administration of a safe reducing agent L-cysteine. The RGD specifically recognized the integrins overexpressed on various malignant tumors and mediated efficient internalization in the synergistic effect of the RGD and TAT. Invitro cellular uptake and 3D tumor spheroids penetration studies demonstrated that the system could not only be selectively and efficiently taken up by cells overexpress ingintegrins but also penetrate the tumor cells to reach the depths of the avascular tumor spheroids. In vivo imaging and fluorescent images of tumor section further demonstrated that this system achieved profoundly improved distribution within tumor tissues, and the RGD and TAT ligands on C-R/T liposomes produced a strong synergistic effect that promoted the uptake of liposomes into cells after the systemic administration of L-cysteine. The results of this study demonstrated a tremendous potential of this multistage liposomes for efficient delivery to tumor tissue and selective internalization into tumor cells.

Abstract
BACKGROUND AND PURPOSE Endostatin (ES) is a c-terminal proteolytic fragment of collagen XVIII with promising antitumour properties in several tumour models, including human glioblastoma. We hypothesized that this peptide could interact with plasma membrane ion channels and modulate their functions. EXPERIMENTAL APPROACH Using cell proliferation and migration assays, patch clamp and Western blot analysis, we studied the effects of ES on the proliferation and migration of human glioblastoma U87 cells, mediated by T-type Ca²⁺ channels. KEY RESULTS Extracellular application of ES reversibly inhibited T-type Ca²⁺ channel currents (T-currents) in U87 cells, whereas L-type Ca²⁺ currents were not affected. This inhibitory effect was associated with a hyperpolarizing shift in the voltage-dependence of inactivation but was independent of G-protein and protein tyrosine kinase-mediated pathways. All three α₁ subunits of T-type Ca²⁺ channels (Ca(V) 3), α(1G) (Ca(V) 3.1), α(1H) (Ca(V) 3.2) and α(1I) (Ca(V) 3.3), were endogenously expressed in U87 cells. Using transfected HEK293 or CHO cells, we showed that only Ca(V) 3.1 and Ca(V) 3.2, but not Ca(V) 3.3 or Ca(V) 1.2 (L-type), channel currents were significantly inhibited. More interestingly, ES inhibited the proliferation and migration of U87 cells in a dose-dependent manner. Pretreatment of the cells with the specific T-type Ca²⁺ channel blocker mibefradil occluded these inhibitory effects of ES. CONCLUSION AND IMPLICATIONS This study provides the first evidence that the antitumour effects of ES on glioblastoma cells is through direct inhibition of T-type Ca²⁺ channels and gives new insights into the future development of a new class of antiglioblastoma agents that target the proliferation and migration of these cells.
