Abstract
The repair of infected bone defects (IBDs) is still a great challenge in clinic. A successful treatment for IBDs should simultaneously resolve both infection control and bone defect repair. Hydrogels are water-swollen hydrophilic materials that maintain a distinct three-dimensional structure, helping load various antibacterial drugs and biomolecules. Hybrid hydrogels may potentially possess antibacterial ability and osteogenic activity. This review summarizes the recent progress of different kinds of antibacterial agents (including inorganic, organic, and natural) encapsulated in hydrogels. Several representative hydrogels of each category and their antibacterial mechanism and effect on bone repair are presented. Moreover, the advantages and disadvantages of antibacterial agent hybrid hydrogels are discussed. The challenge and future research directions are further prospected.

Abstract
Extensive research over past few decades has highlighted the challenges of chemotherapy and prompted the need for multimodality therapy because chemotherapy alone cannot fully eradicate the tumor due to physiological barriers in its effective delivery and systemic side effects. It can be mitigated by adopting nanoparticles as more effective delivery method, but none of them completely prevents drug toxicities. Utilizing multiple therapeutic modes such as phototherapy that can act synergistically with chemotherapy in controlling tumor growth, while reducing the overall dosage, could become a preferred route for cancer management. Careful selection of nanoparticle system, which can simultaneously deliver both drug and photosensitizer, can significantly enhance the therapeutic outcome. Therefore, in this paper, we report development and potential of immune-compatible and long circulating nanoerythrosomes for enhancing the therapeutic potential of camptothecin and indocyanine green against murine cancer model. The RBCs membrane simultaneously loaded the nonpolar drug and amphiphilic photosensitizer in its lipid bilayer, which self-assembled to form stable nanoparticles. These nano constructs absorbed light in the near-infrared region and hence are suitable for targeting deep seated tissues. The dual chemo-phototherapy had great effect on cell viability and had therapeutic value.

Abstract
This review presents principles and novelties in the field of tissue optical clearing (TOC) technology, as well as application for optical monitoring of drug delivery and effective antimicrobial phototherapy. TOC is based on altering the optical properties of tissue through the introduction of immersion optical cleaning agents (OCA), which impregnate the tissue of interest. We also analyze various methods and kinetics of delivery of photodynamic agents, nanoantibiotics and their mixtures with OCAs into the tissue depth in the context of antimicrobial and antifungal phototherapy. In vitro and in vivo studies of antimicrobial phototherapies, such as photodynamic, photothermal plasmonic and photocatalytic, are summarized, and the prospects of a new TOC technology for effective killing of pathogens are discussed.

Abstract
Photodynamic therapy (PDT) is a mild but effective method to treat certain types of cancer upon irradiation with visible light. Here, three isomeric methylpyridinium alkynylanthracenes 1o─p were evaluated as sensitizers for PDT. Upon irradiation with blue or green light, all three compounds show the ability to initiate strand breaks of plasmid DNA. The mayor species responsible for cleavage is singlet oxygen (1 O2 ) as confirmed by scavenging reagents. Only isomers 1m and 1p can be incorporated into HeLa cells, whereas isomer 1o cannot permeate through the membrane. While isomer 1m targets the cell nucleus, isomer 1p assembles in the cellular cytoplasm and impacts the cellular integrity. This is in accordance with a moderate toxicity of 1p in the dark, whereas 1m exhibits no dark toxicity. Both isomers are suitable as PDT reagents, with a CC50 of 3 μm and 75 nm, for 1p and 1m, respectively. Thus, derivative 1m, which can be easily synthesized, becomes an interesting candidate for cancer therapy.

Abstract
Photodynamic Therapy (PDT) is a therapeutic modality used for several malignant and premalignant skin disorders, including Bowen's disease skin cancers and Superficial Basal Cell Carcinoma (BCC). Several photosensitizers (PSs) have been explored for tumor destruction of skin cancers, after their activation by a light source of appropriate wavelength. Topical release of PSs avoids prolonged photosensitization reactions associated with systemic administration; however, its clinical usefulness is influenced by its poor tissue penetration and the stability of the active agent. Nanotechnology-based drug delivery systems are promising tool to enhance the efficiency for PDT of cancer. This review focuses on PSs encapsulated in nanocarriers explored for PDT of skin tumors.

Abstract
Mitochondria-targeted photodynamic therapy (Mt-PDT), which enables the photogenerated cytotoxic oxygen species with fatal oxidative damage to block mitochondrial functions, has been considered as a promising method to enhance the anticancer effectiveness. Aiming at the challenges of PDT, in the past few decades, numerous mitochondria-targeting molecular agents have been developed to boost the PDT efficacy via directly destroying the mitochondria or activating mitochondria-mediated cell death pathways. Herein, a review for recent advances of Mt-PDT is highlighted including: mitochondrial targeting design principles and strategies, therapeutic performance of mitochondria-targeted agents-mediated PDT as well as the agent-free Mt-PDT. In addition, it puts together the achievements of the combinatory mitochondria-anchoring PDT and other anticancer strategies, demonstrating the advantages provided by Mt-PDT. The existing challenges are discussed and future settlements for the development of mitochondria-specific agents are also forecasted.

Abstract
Ovarian cancer (OC) is the deadliest gynecological cancer. Standard treatment of OC is based on cytoreductive surgery followed by chemotherapy with platinum drugs and taxanes; however, innate and acquired drug-resistance is frequently observed followed by a relapse after treatment, thus, more efficient therapeutic approaches are required. Combination therapies involving phototherapies and chemotherapy (the so-called chemophototherapy) may have enhanced efficacy against cancer, by attacking cancer cells through different mechanisms, including DNA-damage and thermally driven cell membrane and cytoskeleton damage. We have designed and synthesized poly(lactic-co-glycolic) nanoparticles (PLGA NPs) containing the chemo-drug carboplatin (CP), and the near infrared (NIR) photosensitizer indocyanine green (ICG). We have evaluated the drug release profile, the photodynamic ROS generation and photothermal capacities of the NPs. Also, the antitumoral efficiency of the NPs was evaluated using the SKOV-3 cell line as an in vitro OC model, observing an enhanced cytotoxic effect when irradiating cells with an 800 nm laser. Evidence here shown supports the potential application of the biodegradable photoresponsive NPs in the clinical stage due to the biocompatibility of the materials used, the spatiotemporal control of the therapy and, also, the less likely development of resistance against the combinatorial therapy.

Abstract
Melanoma is the most aggressive malignant skin tumor and arises from melanocytes. The resistance of melanoma cells to various treatments results in rapid tumor growth and high mortality. As a local therapeutic modality, photodynamic therapy has been successfully applied for clinical treatment of skin diseases. Photodynamic therapy is a relatively new treatment method for various types of malignant tumors in humans and, compared to conventional treatment methods, has fewer side effects, and is more accurate and non-invasive. Although several in vivo and in vitro studies have shown encouraging results regarding the potential benefits of photodynamic therapy as an adjuvant treatment for melanoma, its clinical application remains limited owing to its relative inefficiency. This review article discusses the use of photodynamic therapy in melanoma treatment as well as the latest progress made in deciphering the mechanism of tolerance. Lastly, potential targets are identified that may improve photodynamic therapy against melanoma cells.

Abstract
Background: There is no doubt that hyperthermia is one of the powerful radiosensitizers. Finding a proper mechanism working in hyperthermia/radiation combination is still pronounced challenge. Objectives: This study is focusing on the anti-cancer activities (anti-proliferative, anti-angiogenic and antiapoptotic) of thermoradiotherapy. Materials and Methods: Liver cancer cell line (HepG2) was treated by 37oC, 40oC and 43oC hyperthermia degrees combined with three radiation doses (2 Gy, 4 Gy and 8 Gy) for 24, 48 and 72 hrs. Cell viability, apoptotic/necrotic cell screening, apoptotic (BAX and FasL) and antiapoptotic (BCL-2 and GRP78) genes, and pro-angiogenic mediators [vascular endothelial- (VEGF) and Platelet derived-growth factors (PDGF) ware investigated. Results: Our data showed that 40oC temperature combined with 4 Gy radiation gives a significant decrease (p<0.05) in cell viability. Maximum cytotoxicity was reported 48 hr post-treatment followed by slight restoration of cell viability after 72 hr. Compared with untreated cells, only 5% of viable cells with a high percentage of apoptotic (31%) and necrotic (63%) cells were demonstrated in 40oC/4 Gy/48 hr group. Expression of pro-apoptotic genes (BAX and FasL) were increased after hyperthermia with apparent elevation in 40oC/4 Gy/48 hr group coincides with moderate expression of antiapoptotic BCL-2 and GRP78 genes. A significant reduction (p<0.001; p<0.05) in VEGF and PDGF levels; respectively was shown at 40oC/4 Gy/48 hr group. Conclusions: This pilot study proposed 40oC mild temperature hyperthermia as a favorable hyperthermal condition with 4 Gy radiotherapy in HCC treatment. A further research has to be performed considering an application of more than one session of radiothermal therapy at 40oC/4 Gy for total abrogation of cancer cells.

Abstract
The present study was designed to compare the effect of indocyanine green (ICG)-enhanced laser (810 nm) thermocoagulation method and photodynamic therapy (PDT) on circumscribed choroidal hemangioma (CCH). A total of 36 patients (36 pair of eyes) diagnosed with CCH in the Ocular Fundus Disease Center of The Affiliated Hospital of Medical College of Ningbo University from June 2010 to January 2016 were selected and randomly divided into two groups. ICG-enhanced thermocoagulation was used to treat 18 patients (18 pair of eyes), and PDT was used to treat the remaining 18 patients (18 pair of eyes). The best corrected visual acuity of the affected eyes was observed before and after treatment, and changes in the tumor were observed through ocular fundus photochromes under the ophthalmoscope. The changes in tumor size and height were examined through B-scan ultrasonography. The changes in serous retinal fluid were examined by optical coherence tomography (OCT). A total of 36 patients were followed-up for 3, 7, 11 and 24 weeks after laser therapy with an average of 18 weeks. It was seen that the subretinal serous exudation disappeared in 36 patients through the fundus examination after treatment, and B-scan ultrasonography showed that the tumor size was reduced. Among 18 patients undergoing ICG-enhanced thermocoagulation treatment, the visual acuity of 72.2% of them was improved, while that of the remaining 27.8% was stable, and there were no patients with decreased visual acuity; the fundus observation showed that when tumor atrophy occurred, the tumor turned white accompanied with mild pigment disorders, but retinal and choroidal normal vessels were not damaged. Among 18 patients undergoing PDT treatment, the visual acuity of 44.4% was increased, that of 50% was stable, and that of 5.6% of the patients was decreased; through fundus observation, tumor atrophy scars and alignment, a large number of hyperplasia or pigment loss and partial vascular occlusion could be seen. The results indicated that in the treatment of CCH, ICG-enhanced laser (810 nm) thermocoagulation and PDT can lead to tumor atrophy and promote the absorption of exudation. However, the damage of ICG-enhanced laser thermocoagulation to normal fundus tissues is significantly smaller than that of PDT, and the former has higher safety.

Abstract
The Food and Drug Administration-approved Indocyanine Green can be used as a photosensitizer to kill cancer cells selectively. Although indocyanine green is advantageous as a photosensitizer in terms of strong absorption in the near-infrared region, indocyanine green-based cancer treatment is still not approved as a clinical method. Some reasons for this are aggregation at high concentrations, rapid clearance of the photosensitizer from the body, low singlet oxygen quantum yield, and the uncertainty concerning its action mechanism. This in vitro study focuses on two of these points: "what is the cell inhibition mechanism of indocyanine green-based therapy?" and "how the dose-dependent aggregation problem of indocyanine green alters its cell inhibition efficiency?" The following experiments were conducted to provide insight into these points. Nontoxic doses of indocyanine green and near-infrared laser were determined. The aggregation behavior of indocyanine green was verified through experiments. The singlet oxygen quantum yield of indocyanine green at different concentrations were calculated. Various indocyanine green and energy densities of near-infrared light were applied to prostate cancer, neuroblastoma, and colon cancer cells. An MTT assay was performed at the end of the first, second, and third days following the treatments to determine the cell viability. Temperature changes in the medium during laser exposure were recorded. ROS generation following the treatment was verified by using a Total Reactive Oxygen Species detection kit. An apoptosis detection test was performed to establish the cell death mechanism and, finally, the cellular uptakes of the three different cells were measured. According to the results, indocyanine green-based therapy causes cell viability decrease for three cancer cell lines by means of excessive reactive oxygen species production. Different cells have different sensitivities to the therapy possibly because of the differentiation level and structural differences. The singlet oxygen generation of indocyanine green decreases at high concentrations because of aggregation. Nevertheless, better cancer cell killing effect was observed at higher photosensitizer concentrations. This result reveals that the cellular uptake of indocyanine green was determinant for better cancer cell inhibition.

Combination of Near Infrared Light-Activated Photodynamic Therapy Mediated by Indocyanine Green with Etoposide to Treat Non-Small-Cell Lung Cancer. Cancers (Basel) 2017; 9:cancers9060063. [PMID: 28587258 PMCID: PMC5483882 DOI: 10.3390/cancers9060063] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2017] [Accepted: 06/01/2017] [Indexed: 11/17/2022] Open
Abstract
Indocyanine green (ICG) has been reported as a potential near-infrared (NIR) photosensitizer for photodynamic therapy (PDT) of cancer. However the application of ICG-mediated PDT is both intrinsically and physiologically limited. Here we report a combination of ICG-PDT with a chemotherapy drug etoposide (VP-16), aiming to enhance the anticancer efficacy, to circumvent limitations of PDT using ICG, and to reduce side effects of VP-16. We found in controlled in vitro cell-based assays that this combination is effective in killing non-small-cell lung cancer cells (NSCLC, A549 cell line). We also found that the combination of ICG-PDT and VP-16 exhibits strong synergy in killing non-small-cell lung cancer cells partially through inducing more DNA double-strand breaks (DSBs), while it has a much weaker synergy in killing human normal cells (GM05757). Furthermore, by studying the treatment sequence dependence and the cytotoxicity of laser-irradiated mixtures of ICG and VP-16, we found that the observed synergy involves direct/indirect reactions between ICG and VP-16. We further propose that there exists an electron transfer reaction between ICG and VP-16 under irradiation. This study therefore shows the anticancer efficacy of ICG-PDT combined with VP-16. These findings suggest that ICG-mediated PDT may be applied in combination with the chemotherapy drug VP-16 to treat some cancers, especially the non-small-cell lung cancer.

Abstract
OBJECTIVE To design and synthesize a novel near-infrared (NIR) fluorescent probe based on indocyanine Green (ICG), that can be applied in imaging living cells. RESULTS A highly fluorescent novel NIR fluorescent probe (IR-793) was synthesized in two steps. IR-793 had better fluorescence and optical stability than ICG. In addition, no obvious cytotoxicity effect of IR-793 was observed and cell viability was above 75% at the maximum concentration (120 nM). IR-793 also exhibited good performance in imaging living A549 cells. CONCLUSION IR-793, a novel NIR fluorescent probe that is stable, low-cost, highly fluorescent and low cytotoxicity, has been designed and synthesized for imaging living cells.

Abstract
The fluorescent dye indocyanine green (ICG) is clinically approved and has been applied for ophthalmic and intraoperative angiography, measurement of cardiac output and liver function, or as contrast agent in cancer surgery. Though ICG is known for its photochemical effects, it has played a minor role so far in photodynamic therapy or techniques for targeted protein-inactivation. Here, we investigated ICG as an antibody-conjugate for the selective inactivation of the protein Ki-67 in the nucleus of cells. Conjugates of the Ki-67 antibody TuBB-9 with different amounts of ICG were synthesized and delivered into HeLa and OVCAR-5 cells through conjugation to the nuclear localization sequence. Endosomal escape of the macromolecular antibodies into the cytoplasm was optically triggered by photochemical internalization with the photosensitizer BPD. The second light irradiation at 690 nm inactivated Ki-67 and subsequently caused cell death. Here, we show that ICG as an antibody-conjugate can be an effective photosensitizing agent. Best effects were achieved with 1.8 ICG molecules per antibody. Conjugated to antibodies, the ICG absorption peaks vary proportionally with concentration. The absorption of ICG above 650 nm within the optical window of tissue opens the possibility of selective Ki-67 inactivation deep inside of tissues.

Abstract
Oxidative stress mediated by photodynamic therapy (PDT) mediates the tumoricidal effect, but has also been shown to induce the expression of prosurvival molecules, such as cyclooxygenase-2 (COX-2), which is involved in tumor recurrences after PDT. However, the molecular mechanism is still not fully understood. In this study, we found that activated p38MAPK could significantly up-regulate the activity and expression of histone acetyltransferase p300 (p300HAT) in A375 and C26 cells treated with ALA-and chlorin e6 (Ce6)-mediated photodynamic treatment. A colony-formation assay showed that PDT-induced cytotoxicity was dramatically elevated in the presence of the p300HAT inhibitor anacardic acid (AA). Further studies showed that increased p300HAT acetylates histone H3 and NF-κB p65 subunit to up-regulate the COX-2 expression, which was reduced by AA or p300HAT shRNA. Using chromatin immunoprecipitation analysis, we found that the augmented acetylation of histone H3 and NF-κB increases their binding to the COX-2 promoter region. These in vitro findings were further verified in mice bearing murine C26 and human A375 tumors treated with liposomal Ce6 mediated PDT. Meanwhile, the combination of PDT and AA resulted in greater tumor regression in BALB/c mice bearing C26 tumors, compared with PDT only or combined with COX-2 inhibitor. Finally, we demonstrated that suppression of the PDT-induced p300HAT activity also resulted in the decreased expression of survivin, restoring caspase-3 activity and sensitizing PDT-treated cells from autophagy to apoptosis due to the Becline-1 cleavage. This study demonstrates for the first time the molecular mechanisms involved in histone modification induced by PDT-mediated oxidative stress, suggesting that HAT inhibitors may provide a novel therapeutic approach for improving PDT response.

Abstract
The aim of this study was to develop multifunctional poly lactide-co-glycolide (PLGA) nanoparticles with the ability to simultaneously deliver indocyanine green (ICG) and docetaxel (DTX) to the brain by surface decoration with the brain-targeting peptide angiopep-2 to achieve combined chemo-phototherapy for glioma under near-infrared (NIR) imaging. ICG was selected as a near-infrared imaging and phototherapy agent and DTX was employed as a chemotherapeutic agent. ICG and DTX were simultaneously incorporated into PLGA nanoparticles with higher stability. These nanoparticles were further decorated with angiopep-2 via the outer maleimide group of 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethyleneglycol)-2000]-maleinimide incorporated in the nanoparticles. The NIR image-guided chemo-phototherapy of the angiopep-2 modified PLGA/DTX/ICG nanoparticles (ANG/PLGA/DTX/ICG NPs) not only highly induced U87MG cell death in vitro, but also efficiently prolonged the life span of the brain orthotopic U87MG glioma xenograft-bearing mice in vivo. Thus, this study suggests that ANG/PLGA/DTX/ICG NPs have the potential for combinatorial chemotherapy and phototherapy for glioma.

Abstract
In this study, we synthesized a Hoechst 33258–conjugated hyaluronated fullerene consisting of Hoechst 33258 (as a target moiety to detect necrotic tumor cells), hyaluronic acid (as a target polymer to bind the CD44 receptor overexpressed on the surface of tumor cells), and fullerene (as a photosensitizing agent). This conjugate self-assembled to form nanoparticles consisting of a hydrophilic block (Hoechst 33258 and hyaluronic acid) and a lipophilic block (fullerene). We utilized these nanoparticles to improve the antitumor efficacy via photodynamic tumor therapy. The HCT-116 cells that were damaged after the first photodynamic tumor therapy (using hyaluronated fullerene nanoparticles) were again targeted using Hoechst 33258–conjugated hyaluronated fullerene nanoparticles (detecting necrotic tissues). The experimental results revealed that the second photodynamic tumor therapy using Hoechst 33258–conjugated hyaluronated fullerene nanoparticles caused significant increases in the in vitro phototoxicity and the in vivo tumor inhibition, thereby suggesting their pharmaceutical potential for designing effective multiple photodynamic tumor therapy treatments.

Abstract
Infections with pathogens could cause serious health problems, such as septicemia and subsequent death. Some of these deaths are caused by nosocomial, chronic, or burn-related wound infections. Photodynamic therapy (PDT) can be useful for the treatment of these infections. Our aim was to investigate the antibacterial effect of indocyanine green (ICG) and 808-nm laser on a rat abrasion wound model infected with the multidrug resistant Staphylococcus aureus strain. Abrasion wounds were infected with a multidrug resistant clinical isolate of S. aureus. ICG concentrations of 500, 1000, and 2000 μg∕ml were applied with a 450 J∕cm2 energy dose. Temperature change was monitored by a thermocouple system. The remaining bacterial burden was determined by the serial dilution method after each application. Wounds were observed for 11 days posttreatment. The recovery process was assessed macroscopically. Tissue samples were also examined histologically by hematoxylin–eosin staining. Around a 90% reduction in bacterial burden was observed after applications. In positive control groups (ICG-only and laser-only groups), there was no significant reduction. The applied energy dose did not cause any thermal damage to the target tissue or host environment. Results showed that ICG together with a 808-nm laser might be a promising antibacterial method to eliminate infections in animals and accelerate the wound-healing process.

Abstract
BACKGROUND Indocyanine green (ICG) is a promising water-soluble photosensitizer for photodynamic therapy (PDT) of tumors. It was reported to have promising phototoxic effect on different cell lines. This study aimed to evaluate the efficacy of ICG as an efficient PS agent for skin cancer induced in mice. METHODS Skin squamous cell carcinoma was induced in female CD-1 mice by 7,12-dimethylbenzanthracene and 12-O-tetradecanoyl-phorbol-13-acetate followed by an ICG/PDT treatment. The laser irradiation for PDT was adjusted to cover the whole body of the mice to make sure that the treatment protocol will be delivered to multiple tumors. RESULTS The treatment of skin cancer by ICG/PDT using intravenously injected ICG initiated tumor cell death and significantly decreased cell proliferation as indicated by the reduction in proliferating cell nuclear antigen positivity. A significant reduction in the inflammatory mediators; tumor necrosis factor-α, nitric oxide and 5-lipoxygenase was reported, however the level of cyclooxygenase-2 (COX-2) was significantly elevated after ICG/PDT treatment. CONCLUSION The proposed ICG/PDT treatment modality showed a significant anti-tumor and anti-inflammatory activity against skin cancer accompanied with COX-2 elevation.

Abstract
Sixteen cases of malignant soft tissue sarcoma (STS; 10 canines and six felines) were treated with a novel triple therapy that combined photodynamic therapy, hyperthermia using indocyanine green with a broadband light source, and local chemotherapy after surgical tumor resection. This triple therapy was called photodynamic hyperthermal chemotherapy (PHCT). In all cases, the surgical margin was insufficient. In one feline case, PHCT was performed without surgical resection. PHCT was performed over an interval of 1 to 2 weeks and was repeated three to 21 times. No severe side effects, including severe skin burns, necrosis, or skin suture rupture, were observed in any of the animals. No disease recurrence was observed in seven out of 10 (70.0%) dogs and three out of six (50.0%) cats over the follow-up periods ranging from 238 to 1901 days. These results suggest that PHCT decreases the risk of STS recurrence. PHCT should therefore be considered an adjuvant therapy for treating companion animals with STS in veterinary medicine.

Abstract
BACKGROUND Indocyanine green (ICG) is a promising photosensitive agent for photodynamic therapy (PDT) of tumors. Encapsulating ICG dye in polymeric nanoparticles based on PEBBLE technology forming (ICG-PEBBLE) could improve the aqueous stability of the entrapped ICG molecules. The study objective is to investigate the PDT effect of free ICG-PEBBLE and its Anti-EGFR conjugate. METHODS Skin squamous cell carcinoma was induced in CD1 mice by dimethylbenzanthracene (DMBA) and 12-O-tetradecanoyl-phorbol-13-acetate (TPA) followed by a PDT protocol for four weeks. RESULTS PDT using ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR decreased skin tumor sizes. Our findings revealed that the inflammatory mediators tumor necrosis factor (TNF-α), nitric oxide (NO), cycloxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), the angiogenic mediator vascular endothelial growth factor (VEGF), and proliferating cell nuclear antigen (PCNA) were decreased, while apoptosis, caspase-3 and histone acetylation were induced in tumor bearing groups after PDT using both of ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR. CONCLUSION The present study indicated the effectiveness of PDT using ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR as an inhibitor modality for tumor size, apoptosis, angiogenesis and tumor inflammation. The conjugating of ICG-PEBBLE to anti-EGFR was found to be more effective in inhibiting VEGF and in increasing caspase-3 compared to free ICG-PEBBLE, but there were no other preferential PDT efficacy.

Molecular cytogenetic evaluation of the efficacy of photodynamic therapy by indocyanine green in breast adenocarcinoma MCF-7 cells. Photodiagnosis Photodyn Ther 2012; 10:194-202. [PMID: 23769286 DOI: 10.1016/j.pdpdt.2012.11.006] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2012] [Revised: 09/22/2012] [Accepted: 11/05/2012] [Indexed: 11/30/2022]
Abstract
BACKGROUND Photodynamic therapy (PDT) is used for the treatment of many types of predominantly epithelial cancers. Photosensitizer is taken up by fast growing tumor cells more actively than by other body cells and is activated by light, generating reactive oxygen species that cause cell death by necrosis or apoptosis. This study aimed to evaluate the efficacy of PDT with indocyanine green (ICG) through the investigation of TP53, HER-2 and TOP2A genes signals as breast cancer gene markers by interphase fluorescence in situ hybridization (nuc-FISH). METHODS The photosynthetizer ICG (200 μM) was applied to breast cancer cell line MCF-7 cells (adenocarcinoma) in combination with laser irradiation (807 nm) exposure for 20 min and then incubated for 12, 24 and 48 h. Cell viability was evaluated using trypan blue. The signals for nuc-FISH was investigated and counted for probes specific for the genes TP53 (17p13), HER-2 (17q11.2-q12), and TOP2A (17q21-q22), and BAC-probes RP11-746M1 in 17p11.2 and RP11-403E9 in 17q11.2. RESULTS The cell viability of MCF-7 did not reduced significantly when the cells were treated with ICG (200 μM) or exposed to laser irradiation for 20 min followed by incubation for 24 h. ICG/PDT treatment with laser irradiation exposure for 20 min reduced the cell viability after incubating cells for 12, 24 and 48 h highly significantly in a time dependent manner. For nuc-FISH analysis, TP53, HER-2, TOP2A, RP11-746M1 and RP11-403E9 signals did not reduce or increase in a significant manner when the cells were treated with ICG or exposed to laser irradiation for 20 min then incubated for 24h. PDT enhanced amplification of TP53 signals from nuc ish 17p13(TP53×2) to nuc ish 17p13(TP53×3) or nuc ish 17p13(TP53×4). However, the signals of HER-2 gene, TOP2A gene and BAC probes were reduced highly significantly when MCF-7 cells were treated with PDT with all time intervals. CONCLUSION ICG/PDT and laser induced cytotoxic effect in MCF-7 cells. Also, PDT enhanced TP53 gene amplification, and reduced HER-2, TOP2A, and BAC probes RP11-746M1 and RP11-403E9 signals. Therefore ICG/PDT can be used for breast cancer treatment. It has the potential to induce apoptotic effect and reduce HER-2 and TOP2A genes propagation. Further in vivo studies are needed to evaluate ICG/PDT as a promising therapeutic approach for breast cancer.

Photodynamic therapeutic activity of indocyanine green entrapped in polymeric nanoparticles. Photodiagnosis Photodyn Ther 2012; 10:173-85. [PMID: 23769284 DOI: 10.1016/j.pdpdt.2012.08.003] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2012] [Revised: 08/10/2012] [Accepted: 08/16/2012] [Indexed: 11/24/2022]
Abstract
BACKGROUND Photodynamic therapy (PDT) is a therapeutic modality involving the use of a photosensitizer agent activated by light of appropriate wavelength to selectively destroy tumor cells. Indocyanine green (ICG) is a promising photosensitive agent for PDT of tumor cells. The main disadvantage of using ICG in PDT is the instability of ICG in aqueous solutions. Encapsulating ICG dye in a biocompatible matrix based on PEBBLE technology showed an improvement of aqueous stability comparing with free ICG dye. The main objective of this study is to investigate the photodynamic effect of ICG-ormosil PEBBLEs on two different cell lines: human breast adenocarcinoma cells (MCF-7) and hepatocellular carcinoma cells (HepG2). METHODS ICG-embedded ormosil PEBBLEs were synthesized based on a sol-gel process, and characterized by transmission electron microscopy and other fluorescence tests. The cell viability was evaluated by MTT and trypan blue assays. Apoptosis, necrosis, and DNA damage (comet assay), were evaluated by fluorescence microscopic tests. RESULTS The results declared that ICG-ormosil PEBBLEs and free ICG both have the same cytotoxic and phototoxic effect on MCF-7 and HepG2 cell lines, where the apoptotic mode of cell death is preferentially occurred in case of PDT using ICG-ormosil PEBBLEs. Both ICG and ICG-ormosil PEBBLEs induced DNA damage after laser exposure. These results would suggest that entrapping ICG in Polymeric nanoparticles forming ICG-ormosil PEBBLEs improve the aqueous stability of the photosensitizer and in the same time retain its photodynamic activity, suggesting that it is preferred to use ICG-ormosil PEBBLEs instead of free ICG dye.

Abstract
This study was undertaken to evaluate the effects of indocyanine green as a sensitizer in both photodynamic and radiation therapy on MCF-7 human breast cancer cells line. The cells were incubated with indocyanine green at different concentrations for 24h and were then exposed in the independent treatment groups to a non-coherent light at different fluence rates and X-ray ionizing radiation at different dose rates. In addition, combination effects of this chemo, photo, and radiotherapy were evaluated. The percentage of the cell survival was investigated using the MTT assay. The results showed that indocyanine green had no significant cytotoxic effects up to 100 μM but as a photosensitizer had a strong cytotoxic effect on cancer cells. Despite, indocyanine green could not act as a radiosensitizer. Furthermore, it is surprising to find that 50 μM of indocyanine green in combination with light at 60 J/cm(2) and 4 Gy of X-ray radiation astonishingly killed cancer cells and reduced the percentage of viable cancer cells to be 3.42%. According to the findings, we observed the same efficacy of treatment by adding a low dose of radiation and reducing light fluence rate. In fact, it appears from our data that the adverse effects of photodynamic therapy can be partially abated without reducing the efficacy of treatment. Obviously, this new therapeutic avenue in breast cancer therapy could be worth further investigation and elucidation and should be tested in vivo models for being applied in human therapy.

Abstract
This review updates the recent advances and applications of three prominent synchrotron radiation techniques, microprobe X-ray fluorescence spectroscopy/imaging, X-ray absorption spectroscopy, and infrared microspectroscopy, and highlights how these tools are useful to the medicinal chemist. A brief description of the principles of the techniques is given with emphasis on the advantages of using synchrotron radiation-based instrumentation rather than instruments using typical laboratory radiation sources. This review focuses on several recent applications of these techniques to solve inorganic medicinal chemistry problems, focusing on studies of cellular uptake, distribution, and biotransformation of established and potential therapeutic agents. The importance of using these synchrotron-based techniques to assist the development of, or validate the chemistry behind, drug design is discussed.

Abstract
We examined the effects of photodynamic hyperthemal therapy (PHT), which is a combination of photodynamic therapy (PDT) and hyperthermia (HT), on the apoptosis and cell cycle progression of murine melanoma B16F10 cells. The percentage of apoptotic cell was determined by flow cytometry using fluorescein isothiocyanate (FITC)-conjugated Annexin V and propidium iodide (PI) double staining. The cell cycle analysis was performed by PI staining with flow cytometry. The expression of cyclins and heat shock protein 70 (Hsp70) were examined by a Western blotting analysis. PHT induces death in B16F10 cells, and PHT-mediated apoptosis occurred acutely and persistently in vitro. Our study demonstrated that PHT using indocyanine green (ICG) and near infrared (NIR) light source induces apoptosis and G0/G1 cell cycle arrest in the B16F10 cells.

Abstract
Leukemia is one of the most common and aggressive adult cancers, as well as the most prevalent childhood cancer. Leukemia is a cancer of the hematological system and can be divided into a diversity of unique malignancies based on the onset of the disease as well as the specific cell lineages involved. Cancer stem cells, including recently identified leukemia stem cells (LSCs), are hypothesized to be responsible for cancer development, relapse, and resistance to treatment, and new therapeutics targeting these cellular populations are urgently needed. Nontoxic and nonaggregating calcium phosphosilicate nanoparticles (CPSNPs) encapsulating the near-infrared fluoroprobe indocyanine green (ICG) were recently developed for diagnostic imaging and drug delivery as well as for photodynamic therapy (PDT) of solid tumors. Prior studies revealed that specific targeting of CPSNPs allowed for enhanced accumulation within breast cancer tumors, via CD71 targeting, or pancreatic cancer tumors, via gastrin receptor targeting. In the present study, ICG-loaded CPSNPs were evaluated as photosensitizers for PDT of leukemia. Using a novel bioconjugation approach to specifically target CD117 or CD96, surface features enhanced on leukemia stem cells, in vitro ICG-CPSNP PDT of a murine leukemia cell line and human leukemia samples were dramatically improved. Furthermore, the in vivo efficacy of PDT was dramatically enhanced in a murine leukemia model by utilizing CD117-targeted ICG-CPSNPs, resulting in 29% disease-free survival. Altogether, this study demonstrates that leukemia-targeted ICG-loaded CPSNPs offer the promise to effectively treat relapsing and multidrug-resistant leukemia and to improve the life of leukemia patients.

Abstract
It is well accepted that near-infrared (NIR) lasers are appropriate to ablate benign lesions and induce irreversible thermal injury in deeply seated blood vessels. At this wavelength, the laser light penetrates deep (3-5 mm) into the skin. However, many researchers have reported noticeable pain, extending from mild to severe, during and immediately after NIR laser treatment. Intravenous administration of an exogenous chromophore [indocyanine green (ICG), dye] can effectively convert NIR laser light into heat. In this approach, the presence of ICG has shown to enhance thermal injury of blood vessels in the treatment of healthy tissues. However, the effectiveness of thermal injury on the regression of cutaneous carcinomas during ICG/NIR laser therapy has not been assessed. The purpose of our study was to evaluate the potential benefit of using ICG/NIR laser therapy to regress superficial carcinoma with thermal injury. Two groups of A/J mice with subcutaneous mammary adenocarcinoma tumors (7-9 mm) were irradiated with a 808-nm NIR laser preceded by tail vein injection of ICG dye or sterile saline. Histological evaluation of the subcutaneous tissue revealed minor thermal damage and necrosis in the laser/saline group and substantial damage (up to 100% necrosis) in the laser/ICG group. The laser/ICG-treated group showed a steady reduction in tumor volume compared to the laser/saline group: 48% by day 5 (p = 0.045) and 69-70% by days 8, 9 and 10 (p values 0.0005 or less). The vascular-targeted ICG-NIR laser therapy appears to have potential for treating superficial tumors.

Abstract
We study fluorescence lifetime of indocyanine green (ICG) using femtosecond laser and sensitive detection based on time-correlated single-photon counting. A time-resolved multichannel spectral system is constructed and applied for determination of the fluorescence lifetime of the ICG in different solvents. Emission properties of ICG in water, milk, and 1% intralipid solution are investigated. Fluorescence of the fluorophore of different concentrations (in a range of 1.7-160 μM) dissolved in different solutions is excited by femtosecond pulses generated with the use of Ti:Sa laser tuned within the range of 740-790 nm. It is observed that fluorescence lifetime of ICG in water is 0.166 ± 0.02 ns and does not depend on excitation and emission wavelengths. We also show that for the diffusely scattering solvents (milk and intralipid), the lifetime may depend on the dye concentration (especially for large concentrations of ICG). This effect should be taken into account when analyzing changes in the mean time of arrival of fluorescence photons excited in ICG dissolved in such optically turbid media.

Abstract
Metastatic malignant melanoma remains one of the most dreaded skin cancers worldwide. Numerous factors contribute to its resistance to hosts of treatment regimes and despite significant scientific advances over the last decade in the field of chemotherapeutics and melanocytic targets, there still remains the need for improved therapeutic modalities. Photodynamic therapy, a minimally invasive therapeutic modality has been shown to be effective in a number of oncologic and non-oncologic conditions. Using second-generation stable, lipophilic photosensitizers with optimised wavelengths, PDT may be a promising tool for adjuvant therapy in combating melanoma. Potential targets for PDT in melanoma eradication include cell proliferation inhibition, activation of cell death and reduction in pro-survival autophagy and a decrease in the cellular melanocytic antioxidant system. This review highlights the current knowledge with respect to these characteristics and suggests that PDT be considered as a good candidate for adjuvant treatment in post-resected malignant metastatic melanoma. Furthermore, it suggests that primary consideration must be given to organelle-specific destruction in melanoma specifically targeting the melanosomes - the one organelle that is specific to cells of the melanocytic lineage that houses the toxic compound, melanin. We believe that using this combined knowledge may eventually lead to an effective therapeutic tool to combat this highly intractable disease.

Abstract
Current efforts in structural biology aim to integrate structural information within the context of cellular organization and function. X-rays and infrared radiation stand at opposite ends of the electromagnetic spectrum and act as complementary probes for achieving this goal. Intense and bright beams are produced by synchrotron radiation, and are efficiently used in the wavelength domain extending from hard X-rays to the far-infrared (or THz) regime. While X-ray crystallography provides exquisite details on atomic structure, Fourier transform infrared microspectroscopy (FTIRM) is emerging as a spectroscopic probe and imaging tool for correlating molecular structure to biochemical dynamics and function. In this manuscript, the role of synchrotron FTIRM in bridging the gap towards 'functional biology' is discussed based upon recent achievements, with a critical assessment of the contributions to biological and biomedical research.
