Abstract
Xanthotoxin (XAT) is a natural furanocoumarins, a bioactive psoralen isolated from the fruit of the Rutaceae plant Pepper, which has received increasing attention in recent years due to its wide source and low cost. By collecting and compiling literature on XAT, the results show that XAT exhibits significant activity in the treatment of various diseases, including neuroprotection, skin repair, osteoprotection, organ protection, anticancer, antiinflammatory, antioxidative stress and antibacterial. In this paper, we review the pharmacological activity and potential molecular mechanisms of XAT for the treatment of related diseases. The data suggest that XAT can mechanistically induce ROS production and promote apoptosis through mitochondrial or endoplasmic reticulum pathways, regulate NF-κB, MAPK, JAK/STAT, Nrf2/HO-1, MAPK, AKT/mTOR, and ERK1/2 signaling pathways to exert pharmacological effects. In addition, the pharmacokinetics properties and toxicity of XAT are discussed in this paper, further elucidating the relationship between structure and efficacy. It is worth noting that data from clinical studies of XAT are still scarce, limiting the use of XAT in the clinic, and in the future, more in-depth studies are needed to determine the clinical efficacy of XAT.

Pharmaceutics 2021; 13:pharmaceutics13101558.

Abstract
Extracorporeal photopheresis (ECP), an immunomodulatory therapy for the treatment of chronic graft-versus-host disease (cGvHD), exposes isolated white blood cells to photoactivatable 8-methoxypsoralen (8-MOP) and UVA light to induce the apoptosis of T-cells and, hence, to modulate immune responses. However, 8-MOP-ECP kills diseased and healthy cells with no selectivity and has limited efficacy in many cases. The use of 5-aminolevulinic acid (ALA) and light (ALA-based photodynamic therapy) may be an alternative, as ex vivo investigations show that ALA-ECP kills T-cells from cGvHD patients more selectively and efficiently than those treated with 8-MOP-ECP. The purpose of this phase I-(II) study was to evaluate the safety and tolerability of ALA-ECP in cGvHD patients. The study included 82 treatments in five patients. One patient was discharged due to the progression of the haematological disease. No significant persistent changes in vital signs or laboratory values were detected. In total, 62 adverse events were reported. Two events were severe, 17 were moderate, and 43 were mild symptoms. None of the adverse events evaluated by the internal safety review committee were considered to be likely related to the study medication. The results indicate that ALA-ECP is safe and is mainly tolerated well by cGvHD patients.

Abstract
Background We explored the mechanisms underlying tumorigenesis in oral tongue squamous cell carcinoma (OTSCC) with the goal of uncovering prognostic molecular biomarkers. Methods An mRNA sequencing dataset was obtained from The Cancer Genome Atlas (TCGA) database, and differentially expressed genes (DEGs) were selected using R language software packages. Functional enrichment analysis was conducted with DAVID software and protein-protein interaction (PPI) networks were constructed using the STRING database. The relationship between hub genes and overall survival (OS) was evaluated by Kaplan-Meier analysis and Cox proportional hazard regression models. Expression of the candidate gene, carbonic anhydrase 9 (CA9), was verified by real-time RT-PCR, western blotting, and immunohistochemistry. Results DEGs (n=581) were obtained from 11 OTSCC samples and corresponding adjacent non-tumor tissues. Gene ontology (GO) analysis revealed that most DEGs were implicated in anterior/posterior pattern specification, embryonic skeletal system morphogenesis, and multicellular organism development, and pathway analysis suggested that DEGs were associated with neuroactive ligand-receptor interaction, calcium signaling pathway and transcriptional misregulation in the cancer. A PPI network consisting of 301 nodes and 2011 edges was constructed and 71 hub genes, with high degrees of connectivity in the network, were identified. Kaplan-Meier analysis of the hub genes indicated that high expression of CA9, LHX1, and KISS1R and low expression of CCKAR were associated with poor OS in OTSCC; however, only CA9 was a significant prognostic factor influencing survival in OTSCC on multivariate analysis. High expression of CA9 was associated with poor pathological T-stage. CA9 tumor specificity was confirmed using the Gene Expression Omnibus (GEO) database and further molecular tests. Conclusions We identified key DEGs that may assist in the molecular understanding of OTSCC. CA9 warrants further exploration as potential prognostic biomarker and therapeutic target in OTSCC.

Abstract
BACKGROUND Extracorporeal photopheresis (ECP) is one of the most widely used and effective cell-based therapies for the treatment of T-cell-mediated diseases. The patients' white blood cells (WBCs) are collected by apheresis and exposed to the photosensitizer 8-methoxypsoralen (8-MOP) and ultraviolet A (UVA) light before retransfusion. The UVA/8-MOP combination has been in use in ECP for more than 4 decades; however, whether ECP can be simplified by UVA light irradiation only has never been analyzed. STUDY DESIGN AND METHODS Peripheral blood mononuclear cells were treated with classical ECP or different UVA light doses only (UVAonly ). Treatment efficacy was investigated by apoptosis induction in WBC subsets, inhibition of T-cell proliferation, and the ability of monocytes to induce allogeneic T-cell expansion and to respond to lipopolysaccharide and interferon-γ stimulation in vitro. RESULTS High-dose UVAonly treatment (5 J/cm2 ) was as efficient as ECP to induce apoptosis within 48 hours. UVAonly treatment modulated the composition of the surviving cells by improving monocyte survival and promoting CD8+ T-cell apoptosis. Both ECP and UVAonly treatment inhibited anti-CD3/anti-CD28 triggered T-cell proliferation. Interestingly, whereas ECP-treated monocytes exhibited a markedly reduced capacity to respond to stimulation and to induce allogeneic T-cell proliferation, UVAonly treatment preserved monocyte functionality to some degree. CONCLUSIONS High-dose UVAonly and standard ECP showed comparable efficacy in inducing apoptosis and inhibiting direct T-cell proliferation. Hence, UVAonly treatment can be a simplified alternative to ECP therapy. Furthermore, increased monocyte survival with partially preserved functionality after UVAonly treatment may provide a novel method for immunoregulation.

Selective Killing of Activated T Cells by 5-Aminolevulinic Acid Mediated Photodynamic Effect: Potential Improvement of Extracorporeal Photopheresis. Cancers (Basel) 2020; 12:cancers12020377. [PMID: 32041351 PMCID: PMC7072277 DOI: 10.3390/cancers12020377] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/21/2020] [Revised: 01/28/2020] [Accepted: 02/04/2020] [Indexed: 01/08/2023] Open
Abstract
Extracorporeal photopheresis (ECP), a modality that exposes isolated leukocytes to the photosensitizer 8-methoxypsoralen (8-MOP) and ultraviolet-A (UV-A) light, is used to treat conditions such as cutaneous T-cell lymphoma and graft-versus-host disease. However, the current procedure of ECP has limited selectivity and efficiency; and produces only partial response in the majority of treated patients. Additionally, the treatment is expensive and time-consuming, so the improvement for this modality is needed. In this study, we used the concept of photodynamic therapy (PDT) with 5-aminolevulinic acid (ALA), a precursor of an endogenously synthesized photosensitizer protoporphyrin IX (PpIX) in combination with blue light to explore the possibility of targeting activated human blood T cells ex vivo. With various T-cell activation protocols, a high ALA-induced PpIX production took place in activated CD3+, CD4+CD25+, and CD8+ T cell populations with their subsequent killing after blue light exposure. By contrast, resting T cells were much less damaged by the treatment. The selective and effective killing effect on the activated cells was also seen after co-cultivating activated and resting T cells. Under our clinically relevant experimental conditions, ALA-PDT killed activated T cells more selectively and efficiently than 8-MOP/UV-A. Monocyte-derived dendritic cells (DCs) were not affected by the treatment. Incubation of ALA-PDT damaged T cells with autologous DCs induced a downregulation of the co-stimulatory molecules CD80/CD86 and also upregulation of interleukin 10 (IL-10) and indoleamine 2,3-dioxygenase expression, two immunosuppressive factors that may account for the generation of tolerogenic DCs. Overall, the data support the potential use of ALA-PDT strategy for improving ECP by selective and effective killing of activated T cells and induction of immune tolerance.

Abstract
The use of photodynamic therapy in cancer still remains limited, partly because of the lack of photosensitizer (PS) specificity for the cancerous tissues. Various molecular tools are available to increase PS efficiency by targeting the cancer cell molecular alterations. Most strategies use the protein-protein interactions, e.g. monoclonal antibodies directed toward tumor antigens, such as HER2 or EGFR. An alternative could be the targeting of the tumor glycosylation aberrations, e.g. T/Tn antigens that are truncated O-glycans over-expressed in numerous tumors. Thus, to achieve an effective targeting, PS can be conjugated to molecules that specifically recognize the Oglycosylation aberrations at the cancer cell surface.

Abstract
Extracorporeal photopheresis (ECP) is an autologous immunomodulatory cell therapy that consists of the ex vivo collection of mononuclear cells (MNCs), which are irradiated with UVA in the presence of the photosensitizing agent 8-methoxypsoralen (8-MOP) to induce cell apoptosis. This photoactivated cell preparation is then reinfused into the patient. While the clinical benefits of ECP are well-demonstrated, no study has yet characterized the influence of variations in the composition of the cell preparation on the efficacy of ECP in vitro. Here, we describe a standardized methodology for the in vitro assessment of ECP that uses the human lymphoma T-cell line and mimics the clinical procedure. By quantifying cell apoptosis, inhibition of cell proliferation, and 8-MOP consumption, we used this approach to characterize the specific influence of key variables on the cellular response to ECP. We found that (i) increases in hematocrit and plasma concentrations attenuated the cellular response to ECP; (ii) plasma concentration was the only variable tested that influenced 8-MOP consumption; and (iii) the loss of efficacy due to variations in the concentration of certain blood components could be counteracted by modulating the UVA dose. This methodology may enable evaluation of other leukapheresis preparation protocols and better determination of the optimal working parameters for ECP.

Abstract
A combination of a photosensitizer with light of matching wavelength is a common treatment modality in various diseases including psoriasis, atopic dermatitis and tumors. DNA damage and production of reactive oxygen intermediates may impact pathological cellular functions and viability. Here we set out to investigate the role of the nuclear DNA nick sensor enzyme poly(ADP-ribose) polymerase 1 in photochemical treatment (PCT)-induced tumor cell killing. We found that silencing PARP-1 or inhibition of its enzymatic activity with Veliparib had no significant effect on the viability of A431 cells exposed to 8-methoxypsoralen (8-MOP) and UVA (2.5J/cm(2)) indicating that PARP-1 is not likely to be a key player in either cell survival or cell death of PCT-exposed cells. Interestingly, however, another commonly used PARP inhibitor PJ-34 proved to be a photosensitizer with potency equal to 8-MOP. Irradiation of PJ-34 with UVA caused changes both in the UV absorption and in the 1H NMR spectra of the compound with the latter suggesting UVA-induced formation of tautomeric forms of the compound. Characterization of the photosensitizing effect revealed that PJ-34+UVA triggers overproduction of reactive oxygen species, induces DNA damage, activation of caspase 3 and caspase 8 and internucleosomal DNA fragmentation. Cell death in this model could not be prevented by antioxidants (ascorbic acid, trolox, glutathione, gallotannin or cell permeable superoxide dismutase or catalase) but could be suppressed by inhibitors of caspase-3 and -8. In conclusion, PJ-34 is a photosensitizer and PJ-34+UVA causes DNA damage and caspase-mediated cell death independently of PARP-1 inhibition.

Abstract
Carbonic anhydrase IX (CAIX) is reportedly overexpressed in several types of carcinomas and is generally considered a marker of malignancy. The current study investigated the association between membrane expression of CAIX and the clinicopathological characteristics in oral squamous cell carcinoma (OSCC) patients. The study used immunohistochemistry to examine CAIX expression in 271 OSCC specimens by tissue microarray (TMA) and assessed the effect of CAIX overexpression and knockdown on migration of oral cancer cells in vitro. We found that CAIX expression was associated with more advanced clinical stages (p = 0.030) and positive lymph node metastasis (p = 0.026). Importantly, CAIX expression was correlated with a poorer patient prognosis in a univariate survival analysis (p = 0.025). Moreover, CAIX suppression by small interfering RNA (siRNA) significantly reduced cellular migration in OECM-1 oral cancer cell. In conclusion, our study showed that the expression of CAIX in OSCC samples can predict the progression of OSCC and survival of OSCC patients in Taiwan.
