Once per life cycle, mitotic nuclear divisions are replaced by meiosis I and II - reducing chromosome number from the diploid level to a haploid genome and recombining chromosome arms by crossing-over. In animals, all this happens during formation of eggs and sperm - in yeasts before spore formation. The mechanisms of reciprocal exchange at crossover/chiasma sites are central to mainstream meiosis. To initiate the meiotic exchange of DNA, surgical cuts are made as a form of calculated damage that subsequently is repaired by homologous recombination. These key events are accompanied by...

Chloroplasts are essential for the survival and flourishing of life on Earth. Over the years, chloroplast biology has been studied in a variety of different organisms, leading to the significant disadvantage that findings which were made by using different experimental systems or species were not always directly cross-comparable. The relatively recent adoption of Arabidopsis thaliana as the model organism of choice for plant science research, across the globe, has led to its emergence as a pre-eminent system for research on chloroplasts and other types of plastid. In Chloroplast...

Because of the huge potential of human embryonic stem (hES) cells, especially the newly developed human induced pluripotent stem (hiPS) cells, in disease treatment and life quality improvement, enormous efforts have been made to develop new methodologies to translate lab discoveries in stem cell research into bed-side clinical technologies. In Human Embryonic and Induced Pluripotent Stem Cells: Lineage-Specific Differentiation Protocols, experts in the field present a comprehensive collection of protocols designed for labs around the world. The topics covered in this detailed volume...

Rhim and Kremer's state-of-the-art volume on Human Cell Transformation: Role of Stem Cells and the Microenvironment highlights the latest findings on the current state of human cell transformation model systems and provides the insight into the molecular and cellular changes involved in the conversion of normal cells to neoplastic cells.

Chapters cover all recently developed novel human cell models. In addition, the rapidly growing fields of knowledge regarding not only stem cells in cancer progression, but also the role of the microenvironments in human carcinogenesis are...

Cell cycle checkpoints control the fidelity and orderly progression of eukaryotic cell division. By controlling the orderly progression of critical cell cycle events such as DNA replication and chromosome segregation and ensuring proper repair of damaged DNA, cell cycle checkpoints function to ensure genome integrity. Mechanisms of checkpoint controls are not only the research focus of investigators interested in mechanisms that regulate the cell cycle, but are also the interests of researchers studying cancer development as it is increasingly clear that loss of cell cycle checkpoints,...

Lysosomes are membrane-surrounded organelles which are present in all animal cells. The importance of this organelle is underlined by an increasing number of human diseases, which are associated with an impaired function of the lysosomal compartment.

This book summarizes the current state-of-the art knowledge about this unique organelle. It addresses the biogenesis of this compartment, the transport of lysosomal proteins, the role of the lysosomal membrane in lysosomal stability and transport, the function of lysosomal proteases and hydrolases, lysosomal storage disorders, and new...

Since its first discovery in the early 90 s, the NF-kB/Rel transcription factor family has drawn the attention of experimental biologists, medical profession, and biotech/pharmaceutical industries for its broad and diverse roles in all aspects of human biology and disease. NF-kB/Rel Transcription Factor Family intends to provide an up-to-date guide to the ever-expanding knowledge in the field of NF-kB/Rel transcription factor family.

Mapping of animal genomes has generated huge databases and several new concepts and strategies, which are useful to elucidate origin, evolution and phylogeny. Genetic and physical maps of genomes further provide precise details on chromosomal location, function, expression and regulation of academically and economically important genes. The series "Genome Mapping and Genomics in Animals" provides comprehensive and up-to-date reviews on genomic research on a large variety of selected animal systems, contributed by leading scientists from around the world.

Animal cell technology is a growing discipline of cell biology which aims to understand structures, functions and behaviors of differentiated animal cells, and also to ascertain their abilities to be used in industrial and medical purposes. The goal of animal cell technology includes accomplishments of clonal expansion of differentiated cells with useful ability, optimization of their culture conditions and pharmaceutically important proteins and the application of animal cells to gene therapy, artificial organs and functional foods.

This book contains the proceedings of the 17th...
