Hypericin-photodynamic therapy induces human umbilical vein endothelial cell apoptosis.
The conventional photosensitizers used in photodynamic therapy (PDT), such as haematoporphyrin (HP), have not yet reached satisfactory therapeutic effects on port-wine stains (PWSs), due largely to the long-term dark toxicity. Previously we have showed that hypericin exhibited potent photocytotoxic effects on Roman chicken cockscomb model of PWSs. However, the molecular mechanism of hypericin-m...
متن کاملPhotodynamic Therapy with Hypericin Improved by Targeting HSP90 Associated Proteins
In this study we have focused on the response of SKBR-3 cells to both single 17-DMAG treatment as well as its combination with photodynamic therapy with hypericin. Low concentrations of 17-DMAG without any effect on survival of SKBR-3 cells significantly reduced metabolic activity, viability and cell number when combined with photodynamic therapy with hypericin. Moreover, IC10 concentation of 1...
متن کاملHypericin in the Dark: Foe or Ally in Photodynamic Therapy?
Photosensitizers (PSs) in photodynamic therapy (PDT) are, in most cases, administered systemically with preferential accumulation in malignant tissues; however, exposure of non-malignant tissues to PS may also be clinically relevant, when PS molecules affect the pro-apoptotic cascade without illumination. Hypericin (Hyp) as PS and its derivatives have long been studied, regarding their photodyn...
متن کاملLiposome and Their Applications in Cancer Therapy
Liposomes, the vesicles of phospholipid bilayer, can encapsulate both hydrophilic and lipophilic drugs and protect them from degradation. Liposomes have been extensively studied and continue to create intense interest in research since their discovery in the mid-1960s. Since then, liposomes have been considered to be the most successful nanocarriers for drug deliver and have made their way to t...
متن کاملHypericin-photodynamic therapy inhibits proliferation and induces apoptosis in human rheumatoid arthritis fibroblast-like synoviocytes cell line MH7A
Objective(s): To elucidate the effects and potential mechanisms of hypericin-photodynamic therapy (HYP-PDT) for treating the human rheumatoid arthritis (RA) fibroblast-like synoviocyte (FLS) MH7A cell-line. Materials and Methods: MH7A cells were subjected to HYP-PDT intervention and apoptosis was evaluated via MTT, nuclear staining, and flowcytometry analyses. Intracellular reactive oxygen spec...
