Photodiagnosis Photodyn Ther 2023; 44:103861. [PMID: 37879425 DOI: 10.1016/j.pdpdt.2023.103861] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2023] [Revised: 10/23/2023] [Accepted: 10/23/2023] [Indexed: 10/27/2023]
Abstract
BACKGROUND We previously developed a site-specific transvascular drug delivery system (DDS) based on photomechanical waves (PMWs) or laser-induced stress/shock waves (LISWs). In this study, we investigated the validity of this method to deliver a clinical photosensitizer, talaporfin sodium (TS), to subcutaneous tumors in mice and to enhance the efficacy of photodynamic therapy (PDT). METHODS TS solution (2.5 mg/kg) was intravenously injected into mice. Immediately thereafter, PMWs were applied to the tumor by irradiating a laser target with a Q-switched ruby laser pulse (0.8 J/cm2). Five hours after TS administration, some tumors were excised to evaluate the depth distribution of the delivered TS under a fluorescence microscope. Other tumors were subjected to PDT by irradiating the tissues with a 665 nm continuous-wave laser diode (75 mW/cm2, 667 s) at this timepoint. The effects of PDT were evaluated on the basis of the two primary therapeutic mechanisms of TS-mediated PDT: i) damage to tumor cells and ii) damage to endothelial cells of tumor vessels, i.e., the vascular shutdown effect on tumors. RESULTS PMW application significantly increased the accumulation of TS in the tumor parenchyma but not in the tumor vessel walls; the endothelial cell junctions of tumor vessels should be the route of TS delivery enhanced by PMWs. Thus, as a result of PMW application followed by PDT, while the vascular shutdown effect on the tumors was not enhanced, direct damage to the tumor cells was increased, resulting in significant tumor growth retardation without body weight loss for 7 days after treatment.

Abstract
Phototherapies, in the form of photodynamic therapy (PDT) and photothermal therapy (PTT), have great application prospects in the field of biomedical science due to high precision and non-invasiveness. Because of the limited therapeutic efficacy of single phototherapy, researchers start to focus on combined PTT-PDT. Here, we designed a composite nanomaterial for PTT-PDT. H-TiO2 mesoporous spheres were prepared by sol-gel method and hydrogenation treatment. After modification with polydopamine (PDA), they were combined with indocyanine green (ICG) and NPe6 photosensitizers and coated by thermosensitive liposomes to prepare H-TiO2 @PDA@ICG@NPe6 @Lipo nanocomposite component. The results indicated a substantial improvement of the component in the aspects of spectral response range, photothermal conversion efficiency and light absorption performance by modification and photosensitizers, in the absence of any toxicities on cells. Thermal induction and sequential irradiation with 808 nm and 664 nm lasers induced the aggregation of H-TiO2 @PDA@ICG@NPe6 @Lipo at the tumor site to generate hyperthermia and massive reactive oxygen species (ROS), resulting in decreased cell activity or even cell apoptosis and restrained growth of allograft tumors. These findings underscore the favorable effects of H-TiO2 @PDA@ICG@NPe6 @Lipo on the combined phototherapies and provide approaches for the development of nano-drugs in the context of liver cancer.

Photodiagnosis Photodyn Ther 2023; 41:103321. [PMID: 36738905 DOI: 10.1016/j.pdpdt.2023.103321] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2022] [Revised: 02/01/2023] [Accepted: 02/01/2023] [Indexed: 02/05/2023]
Abstract
OBJECTIVE Photoaging is characterized by wrinkles in the skin and the deterioration of the skin barrier function, mainly caused by long-term exposure to ultraviolet (UV) radiation. Photodynamic therapy (PDT) has been shown to treat photoaging. The novel photosensitizer ShengTaiBuFen(STBF) is a derived substance of Chlorin e6(Ce6) that can exert photodynamic effects directly. In this study, we investigated the availability and the mechanism of STBF-PDT in the treatment of photoaging. METHODS Fluorophotometer was used to determine therapeutic parameters for in vivo experiments. Camera photographs, dermoscopy, HE and Masson staining, skin pH, trans epidermal water loss (TEWL), epidermal water content, and sebum testing were used together to evaluate the results of the treatment. Dark toxicity and therapeutic parameters for in vitro experiments were determined by CCK8 analysis. Scratch assay was used to identify the cell migration of STBF-PDT on HaCaT cells. qPCR and Western blot were used to evaluate the TGF-β/Smad signaling pathway in human dermal fibroblast (HDF) cells. RESULTS We investigated the optimal STBF concentration and time of incubation in vivo and in vitro experiments. STBF-PDT improved the skin phenotype of photoaged mice. The skin of photoaged mice treated with 80 J/cm2 STBF-PDT became smooth, while skin flakes were reduced. The epidermis of STBF-PDT-treated mice was thinner, and the cells were neatly arranged, with increased dermal collagen. In vitro, STBF-PDT promoted the migration of HaCaT cells below a light dose of 0.1 J/cm2. HDF cells co-cultured with HaCaT cells treated with low-dose STBF-PDT showed activation of the TGF-β pathway. CONCLUSION As a novel photosensitizer, STBF-mediated low-dose PDT could reverse photoaging via the TGF-β pathway.

Abstract
BACKGROUNDS/AIM Photodynamic therapy (PDT) with Talaporfin sodium (Talaporfin) is an effective and safe treatment for central-type early-stage lung cancer (CELC) that is associated with less skin photosensitivity. However, PDT is mostly performed in hospital for the purpose of light shading management in Japan. It is expected that it will be possible to perform PDT with Talaporfin (Talaporfin-PDT) as a day treatment with ≥14 days of shading management at home. This study aimed to confirm the safety of Talaporfin-PDT as day treatment. METHODS We retrospectively investigated the occurrence of adverse events among consecutive patients who received PDT for CELC in a day treatment setting in the Respiratory Endoscopy Division of our institution between January 2010 and February 2020. RESULTS A total of 12 patients (16 treatments) received day treatment of Talaporfin-PDT. Among the 12 patients, one patient (one treatment) was followed at another hospital. No severe adverse events after treatment were observed among the remaining 11 patients (15 treatments). Mild photosensitivity on a photosensitivity test was observed in 3 (3 treatments) of the 11 patients (15 treatments) but no major photosensitivity was observed. This photosensitivity was a temporary reaction. CONCLUSION Talaporfin-PDT for CELC was safely performed as a day treatment.

Abstract
BACKGROUND Tumor eradication is one of the most important challengeable categories in oncological studies. In this account, besides the molecular genetics methods including cell therapy, gene therapy, immunotherapy, and general cancer therapy procedures like surgery, radiotherapy, and chemotherapy, photodynamic adjuvant therapy is of great importance. Photodynamic therapy (PDT) as a relatively noninvasive therapeutic method utilizes the irradiation of an appropriate wavelength which is absorbed by a photosensitizing agent in the presence of oxygen. In this procedure, a series of events lead to the direct death of malignant cells such as damage to the microvasculature and also the induction of a local inflammatory function. PDT has participated with other treatment modalities especially in the early stage of malignant tumors and has resulted in decreasing morbidity besides improving survival rate and quality of life. High spatial resolution of PDT has attracted considerable attention in the field of image-guided photodynamic therapy combined with chemotherapy of multidrug resistance cancers. Although PDT outcomes vary across the different tumor types, minimal natural tissue toxicity, minor systemic effects, significant reduction in long-term disease, lack of innate or acquired resistance mechanisms, and excellent cosmetic effects, as well as limb function, make it a valuable treatment option for combination therapies. SHORT CONCLUSION In this review article, we tried to discuss the potential of PDT in the treatment of some dermatologic and solid tumors, particularly all its important mechanisms.

JOURNAL OF PHOTOCHEMISTRY AND PHOTOBIOLOGY B-BIOLOGY 2019; 198:111586. [PMID: 31437760 DOI: 10.1016/j.jphotobiol.2019.111586] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/20/2019] [Revised: 07/28/2019] [Accepted: 08/07/2019] [Indexed: 01/08/2023]
Abstract
Metronomic photodynamic therapy (mPDT) has emerged as an attractive treatment for the selective destruction of tumor cells by induction of apoptosis. Here, we compared the effects of mPDT and acute photodynamic therapy (aPDT) on human SW837 colorectal cancer (CRC) cells. CRC cells were subjected to mPDT using various exposure durations, concentrations of 5-aminolevulinic acid (ALA), fluence rates and energy densities. The effects were compared with those induced by aPDT. We found that apoptosis and autophagy were earlier induced to a greater extent by mPDT than by the same dose applied as aPDT. The survival rates for mPDT vs. aPDT were 35.2%, 32.4%,27.6%,31.6% vs. 85.7%, 71.1%, 67.8%, 42.1% after 3, 6, 12, and 24 h PDT, respectively. For the same time points, the apoptotic rates for mPDT vs. aPDT were 43.2%, 47.3%, 54.7%, and 50.3% vs. 14.6%, 17.6%, 27.1%, and 53.2%, respectively. mPDT induced a peak rate of autophagy of 20.0% at 3 h, whereas aPDT induced two smaller peaks at 3 h (14.1%) and 12 h (15.8%). Advanced autophagosomes were more abundant in mPDT- than aPDT-treated cells and appeared earlier after mPDT (3 h) than after aPDT (3-12 h). Western Bloting results showed that the ratio of LC3B-II/β - actin at 3 h was higher (1.04 times) after mPDT than aPDT. Collectively, these datas indicated that ALA-mPDT was more effective than the same dose of ALA-aPDT at inducing SW837 CRC cell death via apoptosis and autophagy. Thus, mPDT may be a superior choice than aPDT for the treatment of human CRC.
