Abstract
A series of amino- and hydroxytetraphenylporphyrin derivatives was found to have activity against the human immunodeficiency virus type 1 (HIV-1) in human peripheral blood mononuclear cells. Activity tends to be associated with increased hydrophilicity of the porphyrins for the porphyrins with one substituent on each phenyl ring but there is no clear pattern for the porphyrins with two substituents on each phenyl ring. The antiviral activity of certain porphyrins has been demonstrated in the absence of light, suggesting a non-photochemical process. Whereas only some of the porphyrins that inhibit HIV-1 in culture inhibit HIV-1 reverse transcriptase in a cell-free system, none of those tested inhibit DNA polymerase α.

Abstract
Photodynamic therapy (PDT) is a novel cancer therapy inducing irreversible photodamage to tumor tissue via photosensitizer-mediated oxidative cytotoxicity. The cellular and molecular responses associated with PDT are only partially understood. We have reported previously the generation of several photosensitizer-specific PDT-resistant cell variants of HT29 human colon adenocarcinoma cells by selecting cells from sequential PDT treatment using different photosensitizers. In this report, we describe the use of messenger RNA (mRNA) differential display to identify genes that were differentially expressed in the parental HT29 cells compared with their resistant variants. In comparison with parental HT29 cells, mRNA expression was increased in the PDT-resistant cell variants for BNIP3, estrogen receptor-binding fragment-associated gene 9, Myh-1c, cytoplasmic dynein light chain 1, small membrane protein I and differential dependent protein. In contrast, expression in the PDT-resistant variants was downregulated for NNX3, human HepG2 3' region Mbol complementary DNA, glutamate dehydrogenase, hepatoma-derived growth factor and the mitochondrial genes coding for 16S ribosomal RNA (rRNA) and nicotinamide adenine dinucleotide (NADH) dehydrogenase subunit 4. The reduction for mitochondrial 16S rRNA in the PDT-resistant variants was confirmed by Northern blotting, and the elevated expression of the proapoptotic BNIP3 in the PDT-resistant variants was confirmed by Northern and Western blotting analysis. We also examined the expression of some additional apoptosis-regulating genes using Western blotting. We show an increased expression of Bcl-2 and heat shock protein 27 and a downregulation of Bax in the PDT-resistant variants. In addition, the mutant p53 levels in the parental HT29 cells were reduced substantially in the PDT-resistant variants. We suggest that the altered expression in several mitochondrial and apoptosis-regulating genes contributes to PDT resistance.

Abstract
The subcellular, cellular and tissue/tumour interactions with non-toxic photosensitizing chemicals plus non-thermal visible light (photodynamic therapy (PDT) are reviewed. The extent to which endothelium/vasculature is the primary target is discussed, and the biochemical opportunities for manipulating outcome highlighted. The nature of tumour destruction by PDT lends itself to imaging outcome by MRI and PET.

Abstract
The binding properties of meso-tetrakis(N-methylpyridinium-4-yl)porphyrin (H(2)TMPyP) to RNA and DNA.RNA hybrid duplexes were studied by absorption and circular dichroism (CD) spectra. The duplexes studied were poly(rA).poly(rU), poly(rA).poly(dT), poly(rI).poly(rC), poly(rI).poly(dC), poly(rG).poly(rC), and poly(rG).poly(dC). The hypochromicity (about 40%) and the bathochromic shift (about 15 nm) of the porphyrin Soret absorption band upon binding were quite similar among the duplexes examined. The large bathochromic shift and hypochromicity suggested a significant perturbation in the porphyrin pi electrons upon binding. H(2)TMPyP was found to bind in a single step to poly(rI).poly(rC), poly(rG).poly(rC), and poly(rG).poly(dC) and in a multistep manner to poly(rA).poly(rU), poly(rA).poly(dT), and poly(rI).poly(dC). The induced CD spectra in the visible range suggested that the porphyrin preferred to bind to the RNA duplexes with self-stacking along the polymer surface and to the hybrids with intercalation, at least at higher duplex load. This implied a distinct conformational difference between the RNA duplexes and DNA.RNA hybrids, and a drug molecule is able to recognize the difference. The number of binding sites per base pairs (n), however, was very different among the RNA duplexes examined. We also found that the intensity of the bisignate-induced CD bands is proportional to the n value. This suggested that the transition moments on the neighboring porphyrins are interacting considerably with each other to produce intense induced CD peaks.

Abstract
Photodynamic therapy (PDT) utilizes the localized delivery of light to activate a photosensitizing drug (such as Photofrin) which is selectively retained by the tumour tissues. The intrinsic in vitro sensitivity of tumour cells to PDT is thought to be an important determinant of clinical tumour response to PDT. In this work we show the feasibility of using a viral capacity assay for adenovirus (Ad) DNA synthesis as an indicator of cellular sensitivity to and recovery from Photofrin-mediated PDT. Rif-1 mouse fibrosarcoma cells and a PDT resistant derivative, Rif-8A, as well as Chinese hamster ovary (CHO) cells and CHO-MDR multi-drug resistant mutant cells were studied. Consistent with the clonogenic survival of these cells, the capacity of PDT-treated cells for Ad DNA synthesis was greater for Rif-8A compared to Rif-1 cells and for CHO-MDR compared to CHO-N cells. Delaying infection of the Rif cells from immediately after, to 6 hours after PDT, resulted in an increased capacity for Ad DNA synthesis, which was greater for Rif-8A compared to Rif-1 cells, suggesting that the increased resistance of Rif-8A cells to PDT results from an elevated recovery and/or repair of PDT damage. The capacity of UV-irradiated cells for Ad DNA synthesis was also greater for Rif-8A compared to Rif-1 cells indicating a cross-resistance of Rif-8A cells to UV. These results suggest some overlap in the types of cellular damage induced by UV and PDT and/or overlap in the pathways for the repair of UV and PDT damage in Rif cells.

Abstract
Photodynamic therapy (PDT) is the treatment of malignant lesions with visible light following systemic or local administration of a photosensitizer or its precursor. Initially, hematoporphyrin derivative and a purified component called Photofrin II was used for clinical PDT. Later on interest has focused on new sensitizers with more favourable absorption as regards light transmission in tissues. Twenty years of clinical experience has revealed that PDT is best applied to early stage cancers. The present review discusses the basic components of PDT and its clinical use in treatment of cancer.

Abstract
Several observations reported in the literature suggest that singlet oxygen (1O2) might play a role in the clastogenic process in Fanconi anemia (FA) cells, and that the antioxidant status of xeroderma pigmentosum (XP) may also be altered. In order to test the ability of FA and XP cells, relative to normal cells, to cope with 1O2 damage, the effects of photosensitization by hematoporphyrin (HP) have been determined (i) on host cell reactivation (HCR) of damaged infecting herpes simplex virus (HSV) or transfecting SV40 DNA, and (ii) on DNA template capability and clonogenicity of treated cells. Results showed no significant difference among the three types of cells, either for the survival of HP-photosensitized HSV, or for the yields of SV40 virus following transfection of cultures with damaged viral DNA. The treatment of cells with HP plus 365-nm light leads to a dose-dependent, homothetic reduction of 18S and 28S ribosomal RNA (rRNA) synthesis, presumably through a mechanism other than the formation of transcription termination sites. After a 24-h post-exposure incubation, the rate of rRNA synthesis was restored to higher than normal levels in all cell lines. Finally, two FA cell lines showed a higher survival to HP photosensitization than two normal cell lines. Another FA cell line and XP-A and XP-C cells were in the range of sensitivity of the two normal strains for this treatment. These results indicate that FA cells possess an antioxidant defense system at least as efficient as that of normal cells for processing 1O2-induced damage.

Abstract
Research involving three important interactions of synthetic cationic porphyrins with nucleic acids: DNA binding, oxidative-reductive strand scission and photosensitized strand scission, is examined retrospectively. The observation that these porphyrins as a class can associate with DNA by intercalative binding, outside binding and outside binding with self-stacking, i.e., the "three-mode binding model", is evaluated with regard to supporting data from several studies including recent evidence from NMR spectroscopy. Results from investigations into the "nuclease-like" activity of the metallo-derivatives of this class of porphyrins are surveyed for demonstrations of base specificity and the mechanism of the chemical interaction. The ability of cationic porphyrins to induce photosensitized damage in DNA is also reviewed with an emphasis on their strand scission activity via a singlet oxygen intermediate.

Abstract
Binding of 5,10,15,20-tetrakis (N-methylpyridinium-4-yl)porphyrin (H2TMPyP4+) and its zinc complex (ZnTMPyP4+) to DNA is demonstrated by their coelectrophoresis and by absorption and fluorescence spectroscopic methods. Topoisomerisation of pBR322 DNA shows that H2TMPyP4+ unwinds DNA as efficiently as ethidium bromide showing that it intercalates at many sites. ZnTMPyP4+ may cause limited unwinding. Marked changes in the fluorescence spectra of the porphyrins are found in the presence of DNA. The fluorescence intensity of either H2TMPyP4+ or ZnTMPyP4+ is enhanced in the presence of poly (d(A-T)), whereas in the presence of poly (d(G-C] the fluorescence intensity of ZnTMPyP4+ is only slightly affected and that of H2TMPyP4+ markedly reduced. Both the porphyrins photosensitize the cleavage of DNA in aerated solution upon visible light irradiation.

Abstract
The subunit arrangement of wheat germ RNA polymerase II was examined using the cleavable cross-linking reagent dithiobis(succinimidyl propionate). Conditions were chosen such that the enzyme was active prior to treatment, and that most of the subunits were reactive towards the reagent. Our results indicate that the enzyme is made up from a central core involving the two large subunits, around which the small subunits are independently arranged. Possible relations between the overall structure and the role of individual subunits in transcription are discussed.
