Abstract
RNA therapeutics represent a rapidly expanding platform with game-changing prospects in personalized medicine. The disruptive potential of this technology will overhaul the standard of care with reference to both primary and specialty care. To date, RNA therapeutics have mostly been delivered parenterally via injection, but topical administration followed by intradermal or transdermal delivery represents an attractive method that is convenient to patients and minimally invasive. The skin barrier, particularly the lipid-rich stratum corneum, presents a significant hurdle to the uptake of large, charged oligonucleotide drugs. Therapeutic oligonucleotides need to be engineered for stability and specificity and formulated with state-of-the-art delivery strategies for efficient uptake. This review will cover various passive and active strategies deployed to enhance permeation through the stratum corneum and achieve effective delivery of RNA therapeutics to treat both local skin disorders and systemic diseases. Some strategies to achieve selectivity between local and systemic administration will also be discussed.

Abstract
All the nanotechnological devices designed for medical purposes have to deal with the common requirement of facing the complexity of a living organism. Therefore, the development of these nanoconstructs must involve the study of their structural and functional interactions and the effects on cells, tissues, and organs, to ensure both effectiveness and safety. To this aim, imaging techniques proved to be extremely valuable not only to visualize the nanoparticles in the biological environment but also to detect the morphological and molecular modifications they have induced. In particular, histochemistry is a long-established science able to provide molecular information on cell and tissue components in situ, bringing together the potential of biomolecular analysis and imaging. The present review article aims at offering an overview of the various histochemical techniques used to explore the impact of novel nanoproducts as therapeutic, reconstructive and diagnostic tools on biological systems. It is evident that histochemistry has been playing a leading role in nanomedical research, being largely applied to single cells, tissue slices and even living animals.

Abstract
The E6 and E7 oncoproteins of high-risk types of human papillomavirus (HR-HPV) are crucial for the development of cervical cancer (CC). Small interfering RNAs (siRNAs) are explored as novel therapies that silence these oncogenes, but their clinical use is hampered by inefficient delivery systems. Modification (pegylation) with polyethylene glycol (PEG) of liposomal siRNA complexes (siRNA lipoplexes) may improve systemic stability. We studied the effect of siRNA targeting HPV16 E6, delivered via cationic liposomes (lipoplexes), on cellular processes in a cervical carcinoma cell line (CaSki) and its potential therapeutic use. Lipoplexes-PEG-HPV16 E6, composed of DOTAP, Chol, DOPE, and DSPE-PEG2000 were prepared. The results showed that pegylation (5% DSPE-PEG2000) provided stable siRNA protection, with a particle size of 86.42 ± 3.19 nm and a complexation efficiency of over 80%; the siRNA remained stable for 30 days. These lipoplexes significantly reduced HPV16 E6 protein levels and restored p53 protein expression, inhibiting carcinogenic processes such as proliferation by 25.74%, migration (95.7%), and cell invasion (97.8%) at concentrations of 20 nM, 200 nM, and 80 nM, respectively. In conclusion, cationic lipoplexes-PEG-HPV16 E6 show promise as siRNA carriers for silencing HPV16 E6 in CC.

Abstract
Chitosan nanoparticles (NPs) serve as useful multidrug delivery carriers in cancer chemotherapy. Chitosan has considerable potential in drug delivery systems (DDSs) for targeting tumor cells. Doxorubicin (DOX) has limited application due to its resistance and lack of specificity. Chitosan NPs have been used for DOX delivery because of their biocompatibility, biodegradability, drug encapsulation efficiency, and target specificity. In this review, various types of chitosan derivatives are discussed in DDSs to enhance the effectiveness of cancer treatments. Modified chitosan-DOX NP drug deliveries with other compounds also increase the penetration and efficiency of DOX against tumor cells. We also highlight the endogenous stimuli (pH, redox, enzyme) and exogenous stimuli (light, magnetic, ultrasound), and their positive effect on DOX drug delivery via chitosan NPs. Our study sheds light on the importance of chitosan NPs for DOX drug delivery in cancer treatment and may inspire the development of more effective approaches for cancer chemotherapy.

Development of ligand modified erythrocyte coated polydopamine nanomedicine to codeliver chemotherapeutic agent and oxygen for chemo-photothermal synergistic cancer therapy.

Abstract
The use of conventional chemotherapy often faces limitations such as severe side effects, weak tumor tissue specificity, and the development of multidrug resistance. To conquer these challenges, numerous novel drug carriers have been designed in recent years. However, due to the complex processes of tumor development, metastasis and recurrence, single chemotherapy cannot fulfill the goals of clinical diverse treatment. In this work, by utilizing the inherent characteristics of surface-modified erythrocyte and the outstanding photothermal conversion capability of polydopamine (PDA), we designed and constructed a biomimetic multifunctional nanomedicine DPPR NPs to codeliver chemotherapeutic agent doxorubicin (DOX) and oxygen. The results showed that DPPR NPs exhibited inspiring features including nanoscale droplet size, good physicochemical stability, and sustained, pH-, and NIR triggered drug release behavior. It can dramatically prolong the systematic circulation time and elevated the drug accumulated level in the tumor site. Moreover, DPPR NPs could be effectively internalized into tumor cells and destroyed the intracellular redox balance to mediate cell apoptosis. It exerted excellent in vivo tumor targeting effect, photothermal conversion efficiency, ultrasound imaging responses, antitumor efficacy, and good compatibility. In summary, DPPR NPs provide a biomimetic drug delivery platform to organically combine chemotherapy and photothermal therapy for precise cancer treatment.

Abstract
Cis-Diaminedichloroplatinum (cisplatin, CDDP) remained among the most widely used anti-cancer agents; however, management of the dose-limiting side effects is still a great hurdle to its therapeutic potential. In the framework of this investigation, novel approach was developed for CDDP encasement within liposome based on the formation of a coordination bond between the platinum (II) atom and a carboxylic group in aspartic acid (AA) and glutamic acid (GA). We have also compared two methods of preparation based on equilibration and conventional lipid film hydration. For this, first FTIR spectra of the conjugates confirmed coordination bond between Pt and the carboxylate moieties. The PEGylated liposomes composed of HSPC, cholesterol and DPPG had a size of 134 to 197 nm and negative zeta potential (-14.20 to -20.90 mv). Cytotoxicity study revealed IC50 values of <7 µg/ml for liposomes. In vivo plasma retention following iv administration indicated the potential of liposome in maintaining cisplatin levels within the circulation, while free cisplatin and cisplatin conjugates were promptly eliminated. Anti-tumor efficacy studies following iv injections at 3 mg/kg cisplatin weekly for three weeks in C26 tumor bearing BALB/c mice demonstrated the potential of the cisplatin liposomes in tumor growth inhibition. Pt-complexes were not as effective as liposomal formulations showing the crucial role of liposomes in maintaining cisplatin levels within blood circulation. Overall, the developed cisplatin liposome seems to be a promising therapeutic approach for targeting solid tumors.

Abstract
Objective Lung cancer has high morbidity and mortality. We aimed to determine the value
of netrin-1 for the diagnosis and chemotherapeutic monitoring of lung
cancer. Methods Thirty pairs of lung cancer tissues and serum were collected. Netrin-1
expression was detected by immunohistochemistry and enzyme-linked
immunosorbent assay. Netrin-1 expression was downregulated in A549 cells
using small interfering RNA, and the effect of netrin-1 on cisplatin-induced
lung cancer cell apoptosis was determined by flow cytometry. Results Netrin-1-positivity was significantly higher in lung cancer tissues than in
paracarcinoma tissues and high expression of netrin-1 was closely related to
a poor prognosis. Serum netrin-1 levels were also significantly higher in
lung cancer patients than in healthy donors, and were higher in patients
with lung cancer before the beginning of chemotherapy compared with after
the completion of four cycles of chemotherapy. Netrin-1 knockdown increased
the rate of cisplatin-induced apoptosis in A549 cells. Conclusions Netrin-1 expression was increased in tissues and serum from lung cancer
patients and decreased after chemotherapy, suggesting that it may be a
potential diagnostic marker and indicator of chemosensitivity. Netrin-1 may
participate in cisplatin resistance by reducing apoptosis, thus providing a
new strategy for addressing chemoresistance in patients with lung
cancer.

Abstract
Single chemotherapy often causes severe adverse effects and drug resistance to limit therapeutic efficacy. As a noninvasive approach, photothermal therapy (PTT) represents an attractive option for cancer therapy due to the benefits of remote control and precise treatment methods. Nanomedicines constructed with combined chemo-photothermal properties may exert synergistic effects and improved antitumor efficacy. In this study, we developed polydopamine (PDA)-coated nanoparticles grafted with folic acid (FA) and polyethylene glycol to transport doxorubicin (DOX) for targeted cancer therapy. The results showed that this delivery vehicle has a nanoscale particle size and narrow size distribution. No particle aggregation or significant drug leakage was observed during the stability test. This system presented excellent photothermal conversion capability under near-infrared light (NIR) laser irradiation due to the PDA layer covering. In vitro dissolution profiles demonstrated that sequential and triggered DOX release from nanoparticles was pH-, NIR irradiation-, and redox level-dependent and could be best fitted with the Ritger-Peppas equation. FA modification effectively promoted the intracellular uptake of nanoparticles by HepG2 cells and therefore significantly inhibited cell recovery and induced tumor cell apoptosis. Compared to the free DOX group, nanoparticles reduced the DOX concentration in the heart to avoid drug-related cardiotoxicity. More importantly, the in vivo antitumor efficacy results showed that compared with the single chemotherapy strategy, the nanoparticle group exerted combined and satisfactory tumor growth inhibition effects with good biocompatibility. In summary, this nanocarrier delivery system can organically combine chemotherapy and PTT to achieve effective and precise cancer treatment.

Abstract
Combination treatment through the co-delivery of drugs and genes by nanoformulations may achieve a synergistic effect. In our previous study, poly(amidoamine) dendronized chitosan derivative (PAMAM-Cs) showed good gene transfection efficiency and low cytotoxicity. Here, we incorporated hydrophobic deoxycholic acid (DCA) onto the chitosan backbone of PAMAM-Cs to obtain an amphiphilic derivative-PAMAM-Cs-DCA, which could self-assemble into cationic nanoparticles (NPs). The resulting NPs with diameters of 140-220 nm can encapsulate the hydrophobic anticancer drug doxorubicin (DOX) in the core while bind pDNA via the positively charged PAMAM shell. PAMAM-Cs-DCA NPs could completely complex with pDNA at a ratio of nitrogen to phosphorous (N/P) low as 1 and the complexes achieved a transfection efficiency up to 74 % at N/P 20. Moreover, low-dose co-delivered DOX could enhance the transgene expression, showing a synergistic effect. These results suggest that PAMAM-Cs-DCA NPs hold great promise to co-deliver chemotherapeutics and nucleic acid drugs.

Abstract
Oestrogens and androgens play important roles in normal and cancerous tissue and have been shown to negatively regulate pigment epithelium-derived factor (PEDF) expression in sex hormone-responsive tumours. PEDF suppresses tumour growth and its downregulation by oestrogen is implicated in tumorigenesis, metastasis, and progression. PEDF expression is reduced in cancerous tissue of the prostate, breast, ovary, and endometrium compared to their normal tissue counterparts, with a link between PEDF downregulation and sex hormone signalling observed in pre-clinical studies. PEDF reduces growth and metastasis of tumour cells by promoting apoptosis, inhibiting angiogenesis, increasing adhesion, and reducing migration. PEDF may also prevent treatment resistance in some cancers by downregulating oestrogen receptor signalling. By interacting with components of the tumour microenvironment, PEDF counteracts the proliferative and immunosuppressive effects of oestrogens, to ultimately reduce tumorigenesis and metastasis. In this review, we focus on sex hormone regulation of PEDF's anti-tumour action in sex hormone-responsive tumours.

Novel Polymeric Hybrid Nanocarrier for Curcumin and Survivin shRNA Co-delivery Augments Tumor Penetration and Promotes Synergistic Tumor Suppression. Front Chem 2020; 8:762. [PMID: 33134256 PMCID: PMC7550741 DOI: 10.3389/fchem.2020.00762] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2020] [Accepted: 07/22/2020] [Indexed: 02/05/2023] Open
Abstract
A major barrier for co-delivery of gene medicine with small molecular chemotherapeutic drugs in solid tumors is the inadequate tumor penetration and transfection. In this study, a novel polymeric nanocarrier with integrated properties of tumor penetration, nuclear targeting, and pH-responsive features was designed, and further used to achieve the synergistic anti-tumor effect of curcumin (CUR) and survivin shRNA (pSUR). The polymeric hybrid nanocarrier was constructed from the FDA-approved polymer PLGA and a novel conjugated triblock polymer W5R4K-PEG2K-PHIS (WPH). CUR and pSUR were simultaneously encapsulated in the dual-drug-loaded nanoparticles (CUR/pSUR-NPs) by a modified double-emulsion solvent evaporation (W/O/W) method. The obtained nanoparticles exhibited better pharmaceutical properties with a uniform spherical morphology and sustained release manners of CUR and pSUR. Excellent features including preferable cellular uptake, efficient endosomal escape, enhanced tumor penetration, and elevated transfection efficiency were further proven. Additionally, a markedly enhanced anti-tumor efficacy for CUR/shRNA-NPs was achieved on SKOV-3 and Hela cells. The synergistic anti-tumor effect involved the inhibition of tumor cell proliferation, induction of cell apoptosis, and the activation of caspase-3 pathways. This work sets up an innovative co-delivery nanosystem to suppress tumor growth, contributing to the development of a comprehensive nanoparticulate strategy for future clinical applications.

Abstract
As one of the leading and most important metal-based drugs, platinum-based pharmaceuticals are widely used in the treatment of solid malignancies. Despite significant side effects and acquired drug resistance have limited their clinical applications, platinum has shown strong inhibitory effects for a wide assortment of tumors. Drug delivery systems using emerging technologies such as liposomes, dendrimers, polymers, nanotubes and other nanocompositions, all show promise for the safe delivery of platinum-based compounds. Due to the specificity of nano-formulations; unwanted side-effects and drug resistance can be largely averted. In addition, combinational therapy has been shown to be an effective way to improve the efficacy of platinum based anti-tumor drugs. This review first introduces drug delivery systems used for platinum and combinational therapeutic delivery. Then we highlight some of the recent advances in the field of drug delivery for combinational therapy; specifically progress in leveraging the cytotoxic nature of platinum-based drugs, the combinational effect of other drugs with platinum, while evaluating the drug targeting, side effect reducing and sitespecific nature of nanotechnology-based delivery platforms.

Abstract
Colorectal cancer (CRC) is a major cause of cancer-related mortality worldwide. Moreover, metastasis is one of the main causes of death in CRC patients. Nanotechnology-based gene therapy has shown significant therapeutic benefits in recent clinical trials for cancer treatment. Recent studies have shown that pigment epithelium-derived factor (PEDF) protein can inhibit tumor growth and metastasis by anti-angiogenesis and pro-apoptosis. In this study, we prepared a PEDF-DNA-loaded liposome for cancer-targeted gene therapy for metastatic CRC using an iRGD peptide. Our results showed that cancer-targeted PEDF-DNA liposomes (R-LP/PEDF) exhibited enhanced inhibitory effects on invasion, migration, and pro-apoptosis of CRC cells in vitro. In addition, it reduced metastasis tumor nodules in lung and prolonged the survival time in a mouse model of metastatic CRC.

Abstract
Combination treatment through simultaneous delivery of anticancer drugs and gene with nano-formulation has been demonstrated to be an elegant and efficient approach for colorectal cancer therapy. Recently, sorafenib being studied in combination therapy in colorectal cancer (CRC) attracted attention of researchers. On the basis of our previous study, pigment epithelium-derived factor (PEDF) loaded nanoparticles showed good effect on CRC in vitro and in vivo. Herein, we designed a combination therapy for sorafenib (Sora), a multi-kinase inhibitor and PEDF, a powerful antiangiogenic gene, in a nano-formulation aimed to increase anti-tumor effect on CRC for the first time. Sora and PEDF were simultaneously encapsulated in PEG-PLGA based nanoparticles by a modified double-emulsion solvent evaporation method. The obtained co-encapsulated nanoparticles (Sora@PEDF-NPs) showed high entrapment efficiency of both Sora and PEDF - and exhibited a uniform spherical morphology. The release profiles of Sora and PEDF were in a sustained manner. The most effective tumor growth inhibition in the C26 cells and C26-bearing mice was observed in the Sora@PEDF-NPs in comparison with none-drug nanoparticles, free Sora, mono-drug nanoparticles (Sora-NPs and PEDF-NPs) and the mixture of Sora-NPs and equivalent PEDF-NPs (Mix-NPs). More importantly, Sora@PEDF-NPs showed lower toxicity than free Sora in mice according to the acute toxicity test. The serologic biochemical analysis and mice body weight during therapeutic period revealed that Sora@PEDF-NPs had no obvious toxicity. All the data demonstrated that the simultaneously loaded nanoparticles with multi-kinase inhibitor and anti-angiogenic gene might be one of the most potential formulations in the treatment of colorectal carcinoma in clinic and worthy of further investigation.

Abstract
Background: Macrophage foam cells (FCs) play a crucial role in the initiation and progression of atherosclerosis. Reducing the formation or inducing the removal of FCs could ameliorate atherosclerosis. The present study examined whether the whole-cell vaccination using FCs could be used as novel prevention and treatment strategies to battle atherosclerosis. Methods: ApoE−/− mice with initial or established atherosclerosis were subcutaneously immunized three times with FCs in Freund's adjuvant. Results: Immunization with FCs resulted in an overt reduction of atherosclerotic lesion in the whole aorta and the aortic root with enhanced lesion stability. Subsequent study in mechanism showed that FCs vaccination dramatically increased CD4+ T cell and CD8+ T cell populations. Immunization with FCs significantly raised the plasma FCs-specific IgG antibodies. Of note, the FCs immune plasma could selectively recognize and bind to FC. FCs immune plasma significantly blocked the process of FCs formation, finally reduced the accumulation of FCs in plaque. Additionally, it was observed that FCs immunization down-regulated the expression level of atherosclerosis related pro-inflammatory cytokines, including IFN-γ, MCP-1, and IL-6 and enhanced the lesion stability with a significant increase in TGF-β1 level and collagen content. Conclusions: These findings demonstrate that the whole-cell vaccination using FCs significantly decreased lesion development and positively modulated lesion progression and stability by targeting FCs. The whole-cell FCs vaccine might represent a potential novel strategy for development of new antibodies and vaccines to the prevention or treatment of atherosclerosis.

Abstract
BACKGROUND While liposomal cisplatin has shown enhanced drug tolerability and higher targeting property as compared with the conventional cisplatin, the doubt remains whether lipoplatin could improve its anticancer efficacy. What's more, there is still no systematic evaluation of the safety profiles of lipoplatin comparing with original cisplatin. Thus, we performed a systematic literature search for randomized clinical trials directly comparing efficacy and safety of liposomal cisplatin versus its conventional nonliposomal cisplatin. METHODS The electronic search was conducted in PubMed, Embase, The Cochrane Library, and ClinicalTrials.gov from inception to February 10, 2018. The pooled odds ratio (OR) and 95% confidence intervals (CIs) of progressive disease (PD), partial response (PR), stable disease (SD), and adverse events (AEs) were obtained to assess the efficacy and safety. Heterogeneity was estimated using the I test (I > 50%, significant heterogeneity). RESULTS The search yielded 5 clinical trials that meet inclusion criteria, with a total of 523 patients. We found that the liposome encapsulated cisplatin was more clinical efficacious than cisplatin as assessed by PD rate (OR, 0.46; 95% CI, 0.28-0.74; P = .002), while subgroup analysis of the only nonsmall cell lung cancer (NSCLC) patients showed higher response rates in PR (OR, 0.46; 95% CI, 0.28-0.74; P = .002) and PD (OR, 0.46; 95% CI, 0.28-0.74; P = .002) simultaneously. In addition, the toxicity meta-analysis revealed lipoplatin was much less toxic than the original cisplatin, with respect to grade 3 to 4 neurotoxicity (OR, 0.18; 95% CI, 0.04-0.74; P = .02), grade 3 to 4 leukopenia (OR, 0.47; 95% CI, 0.26-0.85; P = .01), grade 3 to 4 neutropenia (OR, 0.26; 95% CI, 0.09-0.71; P = .009), grade 1 and 2 nausea/vomiting (OR, 0.50; 95% CI, 0.32-0.77; P = .002), and grade 3 and 4 asthenia (OR, 0.11; 95% CI, 0.03-0.42; P = .001). CONCLUSIONS This meta-analysis revealed that with both NSCLC and squamous cell carcinoma of the head and neck (SCCHN) patients, liposomal cisplatin-based chemotherapy offers significant advantages regarding the PD and reduced toxicities relative to conventional cisplatin.

Abstract
INTRODUCTION In the past decade, messenger RNA (mRNA) has been extensively explored in a wide variety of biomedical applications. However, efficient delivery of mRNA is still one of the key challenges for its broad applications in the clinic. Recently, lipid polymer hybrid nanoparticles (LPNs) are evolving as a promising class of biomaterials for RNA delivery, which integrate the physicochemical properties of both lipids and polymers. We previously developed an N1,N3,N5-tris(2-aminoethyl)benzene-1,3,5-tricarboxamide (TT) derived lipid-like nanomaterial (TT3-LLN) which was capable of effectively delivering multiple types of mRNA. In order to further improve the delivery efficiency of TT3-LLN, in this study, we focused on studying the effects of incorporating different polymers on establishing LPNs and aimed to develop an optimized lipid polymer hybrid nanomaterial for efficient mRNA delivery. METHODS We incorporated a series of biodegradable and biocompatible polymer materials into the formulation of TT3-LLNs to develop LPNs. mRNA delivery efficiency of different LPNs were evaluated and a systematic orthogonal optimization was further carried out. RESULTS Our data indicate that PLGA4 (MW 24,000-38,000 g/mol) dramatically increased delivery efficiency of TT3-LLNs in comparison to other polymers. Further optimization identified PLGA4-7 LPNs (PLGA:mRNA=9:1, mass ratio; TT3:DOPE:Cholesterol:DMG-PEG2000=25:25:45:0.75, molar ratio) as a lead formulation, which displayed significantly enhanced delivery of two types of mRNA in three different human cell lines as compared with TT3-LLNs. CONCLUSIONS Results from this study potentially provide new insights into developing LPNs for mRNA based therapeutics.

Abstract
To achieve superior therapeutic efficacy, the combination chemotherapy using two or more anticancer drugs in clinical practice has been generally accepted as a feasible strategy. On account of the concept of combination chemotherapy, co-delivery of anticancer drugs with nanotechnology gradually becomes a desired strategy and one of the research frontiers on modern drug delivery. In recent years, nano drug co-delivery system (NDCDS), which loads at least two anticancer drugs with different physicochemical and pharmacological properties into a combination delivery system, has achieved rapid development. NDCDS synergistically inhibited the growth of the tumor compared with the free drugs. In this review, we highlighted the current state of co-delivery nanoparticles and the most commonly used nanomaterial, discussed challenges and strategies, and prospect future development.

Abstract
While cancer remains the major cause of death worldwide, nanomaterial (NM)-based diagnosis and treatment modalities are showing remarkable potential to better tackle clinical oncology by effectively targeting therapeutic agents to tumors. NMs can selectively accumulate in solid tumors, and they can improve the bioavailability and reduce the toxicity of encapsulated cytotoxic agents. Additional noteworthy functions of NMs in cancer treatment include the delivery of contrast agents to image tumor sites, delivery of genetic materials for gene therapy, and co-delivery of multiple agents to achieve combination therapy or simultaneous diagnostic and therapeutic outcomes. Although several NM therapeutics have been successfully translated to clinical applications, the gap between the bench and the bedside remains ominously wide. Tumor heterogeneity and the disparity between pre-clinical and clinical studies have been identified as two of the major translational challenges of NM-based cancer therapies. Herein, we review a handful of recent research studies on the use of NMs in cancer therapy and imaging, with a limited discussion on the consequences of tumor heterogeneity and pre-clinical studies on translational research of NM-based delivery systems and propositions in the literature to overcome these challenges.

Garcia-Mazas C, Csaba N, Garcia-Fuentes M. Biomaterials to suppress cancer stem cells and disrupt their tumoral niche. Int J Pharm 2016; 523:490-505. [PMID: 27940172 DOI: 10.1016/j.ijpharm.2016.12.013] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2016] [Revised: 12/02/2016] [Accepted: 12/07/2016] [Indexed: 01/04/2023]
Abstract
Lack of improvement in the treatment options of several types of cancer can largely be attributed to the presence of a subpopulation of cancer cells with stem cell signatures and to the tumoral niche that supports and protects these cells. This review analyses the main strategies that specifically modulate or suppress cancer stem cells (CSCs) and the tumoral niche (TN), focusing on the role of biomaterials (i.e. implants, nanomedicines, etc.) in these therapies. In the case of CSCs, we discuss differentiation therapies and the disruption of critical cellular signaling networks. For the TN, we analyze diverse strategies to modulate tumor hypervascularization and hypoxia, tumor extracellular matrix, and the inflammatory and tumor immunosuppressive environment. Due to their capacity to control drug disposition and integrate diverse functionalities, biomaterial-based therapies can provide important benefits in these strategies. We illustrate this by providing case studies where biomaterial-based therapies either show CSC suppression and TN disruption or improved delivery of major modulators of these features. Finally, we discuss the future of these technologies in the framework of these emerging therapeutic concepts.

Enhanced and Extended Anti-Hypertensive Effect of VP5 Nanoparticles. Int J Mol Sci 2016; 17:ijms17121977. [PMID: 27898022 PMCID: PMC5187777 DOI: 10.3390/ijms17121977] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2016] [Revised: 11/11/2016] [Accepted: 11/18/2016] [Indexed: 02/05/2023] Open
Abstract
Hypertension has become a significant global public health concern and is also one of the most common risk factors of cardiovascular disease. Recent studies have shown the promising result of peptides inhibiting angiotensin converting enzyme (ACE) in lowering the blood pressure in both animal models and humans. However, the oral bioavailability and continuous antihypertensive effectiveness require further optimization. Novel nanoparticle-based drug delivery systems are helpful to overcome these barriers. Therefore, a poly-(lactic-co-glycolic) acid nanoparticle (PLGANPs) oral delivery system, of the antihypertensive small peptides Val-Leu-Pro-Val-Pro (VLPVP, VP5) model, was developed in this study and its antihypertensive effect was investigated in spontaneously hypertensive rats (SHRs) for the first time. The obtained VP5 nanoparticles (VP5-NPs) showed a small particle size of 223.7 ± 2.3 nm and high entrapment efficiency (EE%) of 87.37% ± 0.92%. Transmission electronic microscopy (TEM) analysis showed that the nanoparticles were spherical and homogeneous. The optimal preparation of VP5-NPs exhibited sustained release of VP5 in vitro and a 96 h long-term antihypertensive effect with enhanced efficacy in vivo. This study illustrated that PLGANPs might be an optimal formulation for oral delivery of antihypertensive small peptides and VP5-NPs might be worthy of further development and use as a potential therapeutic strategy for hypertension in the future.

Promising Nanocarriers for PEDF Gene Targeting Delivery to Cervical Cancer Cells Mediated by the Over-expressing FRα. Sci Rep 2016; 6:32427. [PMID: 27576898 PMCID: PMC5006243 DOI: 10.1038/srep32427] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2016] [Accepted: 08/09/2016] [Indexed: 02/05/2023] Open
Abstract
Cervical cancer presents extremely low PEDF expression which is associated with tumor progression and poor prognosis. In this study, folate receptor α (FRα)-targeted nano-liposomes (FLP) were designed to enhance the anti-tumor effect by targeting delivery of exogenous PEDF gene to cervical cancer cells. The targeting molecule F-PEG-Chol was firstly synthesized by a novel simpler method. FLP encapsulating PEDF gene (FLP/PEDF) with a typical lipid-membrane structure were prepared by a film dispersion method. The transfection experiment found FLP could effectively transfect human cervical cancer cells (HeLa cells). FLP/PEDF significantly inhibited the growth of HeLa cells and human umbilical vein endothelial cells (HUVEC cells) and suppressed adhension, invasion and migration of HeLa cells in vitro. In the abdominal metastatic tumor model of cervical cancer, FLP/PEDF administered by intraperitoneal injection exhibited a superior anti-tumor effect probably due to the up-regulated PEDF. FLP/PEDF could not only sharply reduce the microvessel density but also dramatically inhibit proliferation and markedly induce apoptosis of tumor cells in vivo. Moreover, the preliminary safety investigation revealed that FLP/PEDF had no obvious toxicity. These results clearly showed that FLP were desired carriers for PEDF gene and FLP/PEDF might represent a potential novel strategy for gene therapy of cervical cancer.
