PURPOSE The unique mechanism of tumor destruction by photodynamic therapy (PDT), resulting from apoptotic and necrotic killing of tumor cells accompanied by local inflammatory reaction and induction of heat shock proteins (HSPs), prompted us to investigate the antitumor effectiveness of the combination of PDT with administration of immature dendritic cells(More)
Basal cell carcinoma (BCC) is a distinctive manifestation in nevoid basal cell carcinoma syndrome (NBCCS) patients. Both inherited and acquired mutations of patched 1 (PTCH1), a tumor-suppressor gene controlling the activity of Smoothened (SMO), are the primary cause of the constitutive activation of the Hedgehog (HH) pathway, leading to the emergence of(More)
PURPOSE The effectiveness of interleukin (IL)-12-secreting tumor vaccines in the treatment of mouse tumors could be enhanced by concurrent application of cytokines and costimulatory molecules. We investigated the therapeutic potential of IL-12 gene-transduced melanoma vaccine in combination with CpG immunostimulatory oligodeoxynucleotide (ODN) 1826, an(More)
PURPOSE The study was designed to examine the impact of anemia on the antitumor efficacy of photodynamic therapy (PDT) in a murine colon-26 adenocarcinoma model syngeneic with BALB/c mice. EXPERIMENTAL DESIGN Acute hemolytic anemia was induced by a single i.p. injection of phenylhydrazine hydrochloride (150 mg/kg). Anemia induced by i.p. administration of(More)
Lovastatin, a drug successfully used in the clinic to prevent and to treat coronary heart disease, has recently been reported to decrease the incidence of melanoma in lovastatin-treated patients. Lovastatin has also been proved to potentiate antitumor effects of both cisplatin and TNF-alpha in murine melanoma models. Recently, an augmented therapeutic(More)
Photodynamic therapy (PDT), a promising therapeutic modality for the management of solid tumors, is a two-phase treatment consisting of a photosensitizer and visible light. Increasing evidence indicates that tumor cells in regions exposed to sublethal doses of PDT can respond by rescue responses that lead to insufficient cell death. We decided to examine(More)
Lovastatin, the drug used for the treatment of hypercholesterolemia, has previously been reported to exert antitumor activity in experimental murine models. Butyrate and butyric acid derivatives are well known to induce differentiation and apoptosis of tumour cells and also have recently gained acceptance as potential anticancer agents. In this study, we(More)
Neurons are exposed to damaging stimuli that can trigger cell death and subsequently cause serious neurological disorders. Therefore, it is important to define defense mechanisms that can be activated in response to damage to reduce neuronal loss. Here we report that cisplatin (CPDD), a neurotoxic anticancer drug that damages DNA, triggered apoptosis and(More)
Melanoma is one of the most aggressive cancers and its incidence is increasing worldwide. So far there are no curable therapies especially after metastasis. Due to frequent mutations in members of the mitogen-activated protein kinase (MAPK) signaling pathway, this pathway is constitutively active in melanoma. It has been shown that the SONIC HEDGEHOG(More)
In the present study, IL-12 gene-transduced B78-H1 melanoma cells (B78/IL-12) were used in combination with IL-15 to treat melanoma-bearing mice. Genetically modified B78/IL-12 cells, when injected subcutaneously, induced strong activation of antitumour mechanisms resulting in complete loss of tumourigenicity. In a therapeutic model, intratumoural injection(More)
