Product Description
Keeping pace with current discoveries in the study of apoptosis as a key biological regulatory mechanism, this guide analyzes the possible role of apoptosis in the pathogenesis of various disorders including cancer, diabetes, rheumatoid arthritis, and Parkinson's and Alzheimer's diseases. The only monograph to provide an all-encompassing approach to the topic, this guide explores in-vivo and in-vito mechanisms of apoptosis, in-vivo model systems, the genetic regulation of apopotosis, and information spanning key target organs.

In order to verify this information, more studies were needed with an increased number of children. Thus, the aim of the present work was to see if DDT and its metabolites were able to induce apoptosis of PBMC in exposed children. We performed a study in children living in three communities located in southern Mexico. During the year 2003, we studied a total of 61 healthy children; and during the year 2004, 57 children from the same communities were assessed. Apoptosis frequencies in PBMC in these children ranged from 0.10% to 8.30% during 2003 and from 0.12% to 16.20% during 2004, and although we detected exposure to DDT, DDD and DDE, significant association with apoptosis frequencies was found only with DDE blood levels (p=0.010 and 0.040 for 2003 and 2004 respectively). DNA damage and oxidative DNA damage were also studied in 2004 using the comet assay. The association between exposure to DDT or DDE and DNA damage was significant (p=0.004 and p=0.005 respectively), but the association between DDT or DDE and oxidative DNA damage and that of oxidative damage and apoptosis were not significant. Taking into account that DDE is the most persistent metabolite, it would be important to assess the effects of this DDE-induced apoptosis of PBCM in children living in areas where DDT was sprayed.

Product Description
This work addresses the homeostatic balance between the birth and death of cells in tissues, organs and organisms and emphasizes the molecular processes involved in cellular cycles. Aimed at undergraduates, this book is illustrated, using line drawings and cartoons to explain the concepts involved. It should be of use to those studying biology, biomedicine and medicine, and to those involved in laboratory-based cancer studies.

Product Description
The series Cell Engineering is the first and only major reference work on the development of cellular systems for the production of recombinant glycoproteins, gene and cell therapies, drug screening and tissue engineering. This volume on "Apoptosis" is intended to review the state-of-the-art with in-depth assessments of this type of programmed cell death. The aim of the volume is to make the recent developments in apoptotic research readily accessible to biologists, biotechnologists and cellular engineers. The implication of apoptosis in the suppression of diseases and prolonging survival of cells in culture is presented to indicate the great potential of apoptotic research for drug production and the development of human therapies. All chapters are written as self-contained treatments of the important topics in apoptosis that are presented on an essential information basis. Topics covered range from understanding the role of signalling and effector molecules, mathematical modelling of cell death, RNAi tools in apoptosis research, to monitoring and imaging of apoptosis. This volume will be an invaluable resource for biotechnologists and researchers in apoptosis, cell biology, cell culture and molecular medicine.

The high susceptibility of HMC to simian virus 40 (SV40)-mediated transformation is assumed to play a causative role in the pathogenesis of mesothelioma. The aim of this study was to investigate the asbestos-induced DNA damage in cultured HMC and SV40-transformed HMC (MeT-5A) compared with their malignant counterparts, i.e. human mesothelioma cells (MSTO). The time-dependent initiation of DNA-strand breaks as well as the induction of oxidative DNA base modifications were key factors for investigation. HMC, MeT-5A and MSTO cells were exposed to chrysotile and crocidolite asbestos (3@mg/cm^2) during different time periods (1-72h). DNA damage was investigated by use of the Comet assay and alkaline unwinding, the latter in combination with the Fpg protein. The P53 level was analyzed by immunofluorescence, and measurement of apoptosis was conducted by flow cytometry. We found a significant induction of DNA damage in asbestos-treated HMC already after an exposure time of 1.5h. This effect could not be observed in treated MeT-5A and MSTO cells. Also, a time-dependent significant increase in DNA-strand breaks was observed by alkaline unwinding in asbestos-treated HMC, but not in treated MeT-5A and MSTO cells. In none of the three cell lines we could detect oxidative DNA damage recognized by the Fpg protein (e.g. 8-oxo-guanine), up to 24 h after exposure to asbestos. In contrast to what was found in HMC, P53 was over-expressed in untreated MeT-5A and MSTO. The induction of apoptosis by asbestos fibers was suppressed in MeT-5A and MSTO cells. Crocidolite fibers induced the higher genotoxic effects and chrysotile the more pronounced apoptotic effects. We conclude that asbestos induces DNA damage in HMC already after a very short exposure time in the absence of 8-oxo-guanine formation. The presence of SV40-Tag in MeT-5A and MSTO cells results in an increased expression of P53, but not in additive genotoxic effects after exposure to asbestos. The deregulation of the apoptotic pathway may lead to proliferation of genomically damaged cells and finally to the development of mesothelioma.

However, cells can also respond to DSBs by undergoing programmed cell death. The mechanisms underlying the cellular decision on whether to repair and survive or to die are not well understood but may be related to the efficiency of repair or the extent of the damage. Presumably, a few easily reparable DSBs will not result in cell death in most cell types. However, abundant complex DSBs will present a severe challenge to the repair machineries with repeated attempts at repair likely to result in genome instability. For multicellular eukaryotes at least, struggling to complete repair is folly, whereas removal of severely damaged cells is a more sensible strategy. Here we discuss recent evidence linking DSBs to a highly regulated form of cell death termed, apoptosis. In particular, we focus on the roles of the tumour suppressor, p53 and a recently discovered role for an isotype of the linker histone H1. We present a hypothesis that the elevated levels of ssDNA produced during ongoing attempts at DSB repair may be involved in the switch from repair to apoptosis.

Singh, A simple method for accurate estimation of apoptotic cells, Exp. Cell Res. 256 (2000) 328-337] to tobacco root and leaf cells. In this assay, isolated nuclei are embedded in an agarose microgel on a microscope slide and low molecular-weight DNA fragments diffuse into the microgel. Exposure of the roots to hydrogen peroxide significantly increased the average nuclear area of isolated nuclei. After 4 and 24h of recovery, all DNA damage was repaired. The data clearly demonstrate that the manifestation of diffused nuclei upon exposure to hydrogen peroxide is not the result of non-repairable apoptotic or necrotic DNA fragmentation, but represents repairable genotoxin-induced DNA damage. In contrast, treatment with the alkylating agent ethyl methanesulphonate (EMS) followed by 24h of recovery produced a significant increase in the average nuclear area. The contribution of apoptosis to this increase cannot be excluded. Heat treatment of leaves at 50^oC for 1-15min leading to necrosis, and treatment of isolated nuclei with DNase-I, which digests DNA to nucleosome-sized fragments as during apoptosis, also led to a dose-dependent increase in the nuclear area. The use of different fluorochromes (ethidium bromide, DAPI or YOYO-1) for DNA staining yielded similar results in the DNA Diffusion Assay. As all types and sizes of diffused nuclei were observed after EMS and hydrogen peroxide treatments, we were unable to differentiate, on the basis of the structure of the nuclei, between apoptotic or necrotic DNA fragmentation and other types of genotoxin-induced DNA damage in plants.
