Implication of extrinsic and intrinsic apoptotic pathways in the targeted therapy of hepatocellular carcinoma using aptamer-labeled viramidine nanoparticles. BMC Cancer 2022; 22:1106. [PMID: 36309655 PMCID: PMC9617343 DOI: 10.1186/s12885-022-10201-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Accepted: 10/19/2022] [Indexed: 11/10/2022] Open
Abstract
Hepatocellular carcinoma (HCC) is a global health problem with regional differences in epidemiological statistics. Co-assembling the drug nanoparticles and targeting moieties could improve the therapeutic delivery of anti-cancer drugs. In this attempt, we tracked the extrinsic and intrinsic apoptotic pathways in HCC cells using viramidine (VRM)-loaded aptamer (APT) nanoparticles. In these NPs, both APT and VRM act as targeted ligands/drugs to HCC cells. The NPs were characterized using TEM, ESI–MS, FTIR, and 1H NMR. The results showed uniform particles with round and smooth shapes on the nano-scale. SRB-based cytotoxicity was performed and IC50 values were measured for HCC versus normal cells upon the proposed treatments. The flow cytometry technique was applied to determine apoptosis, then confirmed using genetic and protein analyses. In addition, nitric oxide (NO) and its enzyme (iNOS) were analyzed to examine the effect of reactive nitrogen species (RNS) on apoptosis induction. The present findings indicated that Huh-7 cells were more sensitive to APT-VRM NPs than HepG2 cells, recording the lowest IC50 values (11.23 ± 0.23 µM and 16.69 ± 1.12 µM), as well as the highest significant increase in the apoptotic cells (61.5% and 42%), respectively. Intriguingely, normal BHK-21 cells recorded undetectable IC50 values in the applied NPs, confirming their targeted delivery ability. The genetic expression and protein levels of c-FLIP, Bcl-2, and TNF-α were down-regulated, while FADD, caspase 8, caspase 3, caspase 9, and Bax were up-regulated upon treatment with APT-VRM NPs. The prepared VRM NPs labeled with APT could significantly elevate NO via activation of iNOS. In conclusion, APT-VRM NPs bioconjugate interferes with HCC cells through NO-mediated extrinsic and intrinsic apoptosis.

Abstract
Carbon dots (CDs) have been a promising theranostic tool with high biocompatibility and a tailorable fluorescence profile. Herein, we report the synthesis of highly fluorescent amine-functionalized CDs from low molecular weight chitosan (LMWC) and silk-fibroin (SF) blends. The synthesized CDs were quasi-spherical in shape with a size of 3 ± 1.5 nm. A significant increase in fluorescent intensity and quantum yield was achieved upon increasing the SF content due to nitrogen doping. For inducing target specificity to cancer cells, biotin was covalently conjugated to the CDs, and the conjugation was determined by FTIR spectroscopy. The conjugate was further loaded with 5-fluorouracil (5-FU) as a model anti-cancer drug. The MTT assay showed increased cytotoxicity of the conjugated CDs in cancer cells compared to normal cells. The live-cell imaging in MCF-7 cell lines showed bright blue-colored fluorescence and increased internalization of the conjugated CDs than the non-conjugate ones due to receptor-mediated endocytosis.

Abstract
This manuscript aims to provide the latest update on polymeric nanoparticle drug delivery system for breast cancer treatment after 2015 and how research-oriented it is based on the available research data. Therefore, the authors have chosen breast cancer which is the most frequent and common reason for mortality in women worldwide. The first-line treatment for breast cancer treatment is chemotherapy, apart from surgery, radiation and hormonal therapy. Chemotherapy is associated with lesser therapeutics and undesirable side effects and hence. In addition, drug resistance affects the therapeutic dose to the target site. Although various nano-based formulations have been developed for effective treatment, the polymeric nanoparticles effectively avoid the lacunae of conventional chemotherapy. There has been an effort made to understand the chemotherapy drugs and their conventional formulation-related problems for better targeting and effective drug delivery for breast cancer treatment. Thus, the polymeric nanoparticles as a strategy overcome the associated problems with resulting dose reduction, enhanced bioavailability, reduced side effects, etc. This present review has compiled the research reports published from 2015 to 2021 from different databases, such as PubMed, Google Scholar, ScienceDirect, which are related to breast cancer treatment in which the drug delivery of numerous chemotherapeutic agents alone or in combination, including phytoconstituents formulated into various polymer-based nanoparticles.

Abstract
Purpose This study aimed to explain the influence of zein nanosphere (ZN NS) formulation on the pharmacotherapeutic profile of PTS in MCF7 cells. Methods Liquid–liquid phase separation was used to formulate PTS-ZN NSs. The formulations developed were evaluated for particle-size analysis, encapsulation efficiency, and in vitro diffusion. Also, assays of cytotoxicity, uptake, cell-cycle progression, annexin V, apoptotic gene mRNA expression and biochemical assays were carried out. Results The PTS-ZN NS formulation selected showed 104.5±6.2 nm, 33.4±1.8 mV, 95.1%±3.6%, and 89.1%±2.65% average particle size, zeta-potential, encapsulation efficiency and in vitro diffusion, respectively. With MCF7 cells, IC50 was reduced approximately 15-fold, with increased cellular uptake, accumulation in the G2/M phase, increased percentage of cells in the pre-G1 phase, amelioration of early and late apoptosis, raised mRNA expression of CASP3 and CASP7, lower expression of cyclin-CDK1, and enhanced oxidant potential through decreased glutathione reductase (GR) activity, and enhanced reactive oxygen–species generation and lipid-peroxidation products. Conclusion PTS-ZN NSs indicated enhanced antiproliferative, proapoptotic, and oxidant potential toward MCF7 cells compared to free PTS. Ameliorated results of nanosized carriers, cellular uptake, and sustained diffusion may contribute to these outcomes.

Abstract
Thirty-two new diosgenin derivatives were designed, synthesized, and evaluated for their cytotoxic activities in three human cancer cell lines (A549, MCF-7, and HepG2) and normal human liver cells (L02) using an MTT assay in vitro. Most compounds, especially 8, 18, 26, and 30, were more potent when compared with diosgenin. The structure-activity relationship results suggested that the presence of a succinic acid or glutaric acid linker, a piperazinyl amide terminus, and lipophilic cations are all beneficial for promoting cytotoxic activity. Notably, compound 8 displayed excellent cytotoxic activity against HepG2 cells (IC50 = 1.9 μM) and showed relatively low toxicity against L02 cells (IC50 = 18.6 μM), showing some selectivity between normal and tumor cells. Studies on its cellular mechanism of action showed that compound 8 induces G0/G1 cell cycle arrest and apoptosis in HepG2 cells. Predictive studies indicated that p38α mitogen-activated protein kinase (MAPK) is the optimum target of 8 based on its 3D molecular similarity, and docking studies showed that compound 8 fits well into the active site of p38α-MAPK and forms relatively strong interactions with the surrounding amino acid residues. Accordingly, compound 8 may be used as a promising lead compound for the development of new antitumor agents.

Abstract
In the golden age of pharmaceutical nanocarriers, we are witnessing a maturation stage of the original concepts and ideas. There is no doubt that nanoformulations are extremely valuable tools for drug delivery applications; the current challenge is how to optimize them to ensure that they are safe, effective and scalable, so that they can be manufactured at an industrial level and advance to clinical use. In this context, lipid nanoparticles have gained ground, since they are generally regarded as non-toxic, biocompatible and easy-to-produce formulations. Pharmaceutical applications of lipid nanocarriers are a burgeoning field for the transport and delivery of a diversity of therapeutic agents, from biotechnological products to small drug molecules. This review starts with a brief overview of the characteristics of solid lipid nanoparticles and discusses the relevancy of performing systematic preformulation studies. The main applications, as well as the advantages that this type of nanovehicles offers in certain therapeutic scenarios are discussed. Next, pharmacokinetic aspects are described, such as routes of administration, absorption after oral administration, distribution in the organism (including brain penetration) and elimination processes. Safety and toxicity issues are also addressed. Our work presents an original point of view, addressing the biopharmaceutical aspects of these nanovehicles by means of descriptive statistics of the state-of-the-art of solid lipid nanoparticles research. All the presented results, trends, graphs and discussions are based in a systematic (and reproducible) bibliographic search that considered only original papers in the subject, covering a 7 years range (2013-today), a period that accounts for more than 60% of the total number of publications in the topic in the main bibliographic databases and search engines. Focus was placed on the therapeutic fields of application, absorption and distribution processes and current efforts for the translation into the clinical practice of lipid-based nanoparticles. For this, the currently active clinical trials on lipid nanoparticles were reviewed, with a brief discussion on what achievements or milestones are still to be reached, as a way of understanding the reasons for the scarce number of solid lipid nanoparticles undergoing clinical trials.

Abstract
Background: Myocardial infarction (MI) is the most severe ischemic heart disease and di-rectly leads to heart failure till death. Target molecules have been identified in the event of MI including increasing angiogenesis, promoting cardiomyocyte survival, improving heart function and restraining inflammation and myocyte activation and subsequent fibrosis. All of which are substantial in cardiomy-ocyte protection and preservation of cardiac function. Methodology: To modulate target molecule expression, virus and non-virus-mediated gene transfer have been investigated. Despite successful in animal models of MI, virus-mediated gene transfer is hampered by poor targeting efficiency, low packaging capacity for large DNA sequences, immunogenicity induced by virus and random integration into the human genome. Discussion: Nanoparticles could be synthesized and equipped on purpose for large-scale production. They are relatively small in size and do not incorporate into the genome. They could carry DNA and drug within the same transfer. All of these properties make them an alternative strategy for gene transfer. In the review, we first introduce the pathological progression of MI. After concise discussion on the current status of virus-mediated gene therapy in treating MI, we overview the history and development of nanoparticle-based gene delivery system. We point out the limitations and future perspective in the field of nanoparticle vehicle. Conclusion: Ultimately, we hope that this review could help to better understand how far we are with nanoparticle-facilitated gene transfer strategy and what obstacles we need to solve for utilization of na-nomedicine in the treatment of MI.

Abstract
Colon cancer in men and breast cancer in women are regarded as major health burdens, accounting for majority of cancer diagnoses globally. Doxorubicin (DOX) resistance in breast and colon cancers represents the main reason of unsuccessful therapy. The rationale of this study is to explore whether selenium nanoparticles (nano-Se) can overcome this resistance obstacle of DOX nanoparticles (nano-DOX) in these cancerous cells. Nano-Se and nano-DOX were manufactured and characterized using electron microscopy and Malvern ZetaSizer, applied separately or in the form of combinatorial regimen against human breast cancer cells (MCF7 and MDA-MB-231) and human colorectal cancer cells (HCT 116 and Caco-2). Cytotoxicity, early/late apoptosis, necrosis, cellular zinc, glucose uptake, and redox status were assessed after applying different nano-treatments versus their free counterparts. Nano-DOX induces cytotoxicity in MCF7 and Caco-2 more than MDA-MB-231 and HCT 116 cancerous cells. In addition, nano-DOX plus nano-Se diminish MCF7 and Caco-2 chemoresistance higher than MDA-MB-231 and HCT 116 cancerous cells. Moreover, Se and DOX nano-platforms inhibit glucose uptake. Furthermore, nano-DOX increases nitric oxide (NO) and malondialdehyde (MDA) in cancer cells' media, while nano-DOX combination with nano-Se rebalances the redox status with zinc augmentation. We reported that Caco-2 cancer cells are more sensitive than HCT 116 cancer cells to nano-DOX and nano-Se. Nano-DOX plus nano-Se induces cytotoxicity-mediated late apoptosis in Caco-2 more than HCT 116 cell lines. This de novo strategy could have great power to overcome the problem of DOX resistance during colon cancer therapy.

Abstract
Current estimates indicate that hepatocarcinoma is the leading cause of death globally. There is interest in utilizing nanomedicine for cancer therapy to overcome side effects of chemo-interventions. Ribavirin, an antiviral nucleoside inhibitor, accumulates inside red blood cells, causing anemia. Its analog, viramidine, can concentrate within hepatocytes and spare red blood cells, thus limiting anemia. Hepatocarcinoma cells have a large number of asialoglycoprotein receptors on their membranes that can bind galactosyl-terminating solid lipid nanoparticles (Gal-SLN) and internalize them. Here, viramidine, 5-fluorouracil, and paclitaxel-loaded Gal-SLN were characterized inside cells. Cytotoxicities of free-drug, nano-void, and drug-loaded Gal-SLN were evaluated using HepG2 cells; over 3 days, cell viability was measured. To test the mechanistic pathway, we investigated in vitro apoptosis using flow cytometry and in ovo angiogenesis using the CAM assay. Results showed that 1 and 2 μM of the viramidine-encapsulated Gal-SLN had the highest cytotoxic effect, achieving 80% cell death with a steady increase over 3 days, with induction of apoptosis and reduction of necrosis and angiogenesis, compared to free-drugs. Gal-SLN application on breast cancer MCF-7 cells confirmed its specificity against liver cancer HepG2 cells. We conclude that viramidine-encapsulated Gal-SLN has anticancer and anti-angiogenic activities against hepatocarcinoma.

Abstract
Non-small cell lung cancer (NSCLC) and hepatocellular carcinoma (HCC) are very common in certain population around the world. Despite the recent advances in their diagnosis and therapy, their prognosis remains poor due to the development resistance to drug. Although doxorubicin (DOX) is considered to be one of the most anti-solid tumor drugs, developed resistance is contributing to unsuccessful outcome. The rationale of the current study is to explore the sensitizing capability of the DOX-treated cancer cells using the anticancer agents; bevacizumab (avastin; AV) and CCR2 inhibitor (CR) in their free- and nano-formulations. Here, the average size, polydispersity index (PDI), zeta potential, and entrpment effeciency (EE%) of the synthesized nanoparticles were measured. We investigated the effect of these platforms on the proliferation, apoptosis, necrosis, nitric oxide (NO), malondialdehyde (MDA), and zinc levels of human HCC (HepG2 and Huh-7) and NSCLC (A549) cancer cell lines. Glucose consumption rates using Huh-7 and A549 cancer cells were tested upon treatments. We demonstrated that AV and CR nano-treatments significantly suppressed A549 cell viability and activated apoptosis by NO level elevation. We concluded that AVCR NP plus DOX significantly induces A549 cytotoxicity-mediated apoptosis more than Huh-7 and HepG2 cells. This drug-drug nano-combination induced Huh-7 cytotoxicity-mediated apoptosis more than HepG2 cells. In conclusion, AVCR NP sensitized DOX-treated A549 and Huh-7 cells through reactive oxygen species (ROS)-stimulated apoptosis.

Int J Pharm 2019; 563:110-121. [PMID: 30935913 DOI: 10.1016/j.ijpharm.2019.03.056] [Citation(s) in RCA: 50] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/15/2018] [Revised: 03/27/2019] [Accepted: 03/27/2019] [Indexed: 02/06/2023]
Abstract
This research attempts to bring together the positive aspects of lipid nanoparticles and Quality by Design (QbD) approach for developing a novel drug delivery system for skin cancers and aktinic keratosis. Lipid nanoparticles which is one of the most efficacious options for topical treatment of skin diseases were prepared due to their ability to overcome the complex structure of skin barrier and to enhance the skin penetration. Since the formulation development contains complex variables of active ingredients, raw materials or production method; all the variables of the product should be elaborated. QbD approach which refers to design and develop formulations and manufacturing processes to maintain the prescribed product quality was also successfully adopted to achieve a time- and cost-saving process ensuring a high-quality product. 5-Fluorouracil (5-FU) loaded lipid nanoparticles, both solid lipid nanoparticles and nanostructured lipid carriers, were developed and characterized by following QbD steps. Optimal lipid nanoparticle formulation with guaranteed quality which was within the design space has been reached through the artificial neural networks. The optimal lipid nanoparticle formulation which is a NLC formulation with a mean particle size of 205,8 ± 9,34 nm, narrow size distribution (0.279 ± 0.01) and negative zeta potantial -30,20 ± 0,92 was produced by high pressure homogenization method. Cytotoxicity profiles of the optimal NLC was determined by cell culture studies on epidermoid carcinoma cells and human keratinocyte cells. Optimal NLC showed significantly higher anticancer effect on epidermoid carcinoma cells than free 5-FU and also less cytotoxicity towards human keratinocyte cells. Optimal NLC was formulated in hydrogel formulation for ease of application which has suitable occlusive and mechanical properties, viscocity and pH for patient complience. The cumulative amount of 5-FU in dermal tissues of rat skin was found 20.11 ± 2.14 μg/cm2 and 9.73 ± 0.87 μg/cm2 after application of NLC enriched hydrogel and 5-FU hydrogel respectively. In conclusion, this study showed that a time and cost saving process ensuring a high-quality product can be obtained by QbD guided formulation development study with the help of artificial neural networks. A novel semisolid dosage form enriched by NLC which is promising for topical treatment of skin cancers was developed.

Abstract
BACKGROUND Surface functionalization of gold nanoparticles (AuNPs) has emerged as a promising field of research with enormous biomedical applications. The folate (FA)-attached polymer-gold nanoconjugates play vital role in targeting the cancer cells. METHODS AuNPs were synthesized by using di- or tri-carboxylate-polyethylene glycol (PEG) polymers, including citrate-PEG (CPEG), malate-PEG (MAP), and tartrate-PEG (TAP), as a reducing and stabilizing agent. After synthesis of polymer-AuNPs, the freely available hydroxyl and carboxylate groups of CPEG, MAP, and TAP were used to attach a cancer cell-targeting agent, FA, via a 1-Ethyl-3-(3-dimethylaminopropyl) carbodiimide/N-hydroxy succinimide coupling reaction to obtain FA-CPEG-AuNP, FA-MAP-AuNP, and FA-TAP-AuNP nanocon-jugates, respectively. The 5-fluorouracil (5FU) was attached to π back-bonded carbonyl oxygens of the nanoconjugates, and the in vitro drug release profile was studied by high pressure liquid chromatography. Biocompatibility profiles of the FA-CPEG-AuNP, FA-MAP-AuNP, and FA-TAP-AuNP nanoconjugates were investigated using adult human dermal fibroblasts. Anti-breast cancer activity of 5FU-loaded nanoconjugates was investigated using MCF-7 breast cancer cells. RESULTS X-ray photoelectron spectroscopy and Fourier-transform infrared spectroscopy analyses confirmed that AuNPs attached to CPEG, MAP, or TAP via the formation of π back bonding between AuNPs and the ester carbonyl group. The π back-bonded nanoconjugates exhibited sustained release of 5FU up to 27 days. FA-MAP-AuNPs exhibited an IC50 at 5 µg/mL, while FA-CPEG-AuNPs and FA-TAP-AuNPs showed the IC50 at 100 µg/mL toward MCF-7 cancer cells. CONCLUSION The developed polymer π back-bonded multifunctional gold nanoconjugates could be used as a potential drug delivery system for targeting MCF-7 cancer cells.

Abstract
BACKGROUND Acyclovir use is limited by a high frequency of administration of five times a day and low bioavailability. This leads to poor patient compliance. OBJECTIVES To overcome the problem of frequent dosing, we used nanotechnology platform to evaluate the proof of concept of substituting multiple daily doses of acyclovir with a single dose. METHODS Acyclovir was formulated as solid lipid nanoparticles (SLN). The nanoparticles were characterized for particle size, surface charge and morphology and in vitro drug release. The pharmacokinetic and pharmacodynamic of SLN acyclovir were compared with conventional acyclovir in a mouse model. RESULTS SLN showed drug loading of 90.22% with 67.44% encapsulation efficiency. Particle size was found to be of 131 ± 41.41 nm. In vitro drug release showed 100% release in SIF in 7 days. AUC0-∞ (119.43 ± 28.74 μg/ml h), AUMC0-∞ (14469 ± 4261.16 μg/ml h) and MRT (120.10 ± 9.21 h) were significantly higher for ACV SLN as compared to ACV AUC0-∞ (12.22 ± 2.47 μg/ml h), AUMC0-∞ (28.78 ± 30.16 μg/ml h) and MRT (2.07 ± 1.77 h), respectively (p<0.05). In mouse model, a single dose of ACV SLN was found to be equivalent to ACV administered as 400mg TID for 5 days in respect to lesion score and time of healing. CONCLUSION The proof of concept of sustained-release acyclovir enabling administration as a single dose was thus demonstrated.

Abd-Rabou AA, Shalby AB, Ahmed HH. Selenium Nanoparticles Induce the Chemo-Sensitivity of Fluorouracil Nanoparticles in Breast and Colon Cancer Cells. Biol Trace Elem Res 2019; 187:80-91. [PMID: 29748931 DOI: 10.1007/s12011-018-1360-8] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/30/2017] [Accepted: 04/19/2018] [Indexed: 01/02/2023]
Abstract
Drug resistance is a major challenge of breast and colon cancer therapies leading to treatment failure. The main objective of the current study is to investigate whether selenium nanoparticles (nano-Se) can induce the chemo-sensitivity of 5-fluorouracil (FU)-encapsulated poly (D, L-lactide-co-glycolide) nanoparticles (nano-FU) in breast and colon cancer cell lines. Nano-Se and nano-FU were synthesized and characterized, then applied individually or in combination upon MCF7, MDA-MB-231, HCT 116, and Caco-2 cancerous cell lines. Cytotoxicity, cellular glucose uptake, and apoptosis, as well as malondialdehyde (MDA), nitric oxide (NO), and zinc (Zn) levels, were investigated upon the different treatments. We have resulted that nano-FU induced cell death in MCF7 and Caco-2 more effectively than MDA-MB-231 and HCT 116 cell lines. Moreover, nano-FU plus nano-Se potentiate MCF7 and Caco-2 chemo-sensitivity were higher than MDA-MB-231 and HCT 116 cancerous cell lines. It is relevant to note that Se and FU nano-formulations inhibited cancer cell bioenergetics via glucose uptake slight blockage. Furthermore, nano-FU increased the levels of NO and MDA in media over cancer cells, while their combinations with nano-Se rebalance the redox status with Zn increment. We noticed that MCF7 cell line is sensitive, while MDA-MB-231 cell line is resistant to Se and nano-Se. This novel approach could be of great potential to enhance the chemo-sensitivity in breast and colon cancer cells.
