16. Role of Tripeptidyl peptidase II in cell cycle regulation and tumor progression
Abstract : Protein degradation is essential for many cellular functions and the ubiquitin-proteasome system controls the turnover of most cellular proteins and plays a pivotal role in the regulation of basic physiological processes and in the pathogenesis of many diseases. Alterations in the metabolism of proteins involved in the regulation of cell cycle and apoptosis may result in uncontrolled cell division, which em lead to malignant transformation and tumor development One melt example is the Burkitt's lymphoma (BL), a highly malignant B-cell tumor characterized by chromosomal translocations that constitutively activate the c-myc oncogene.

17. Mammalian cell cycle regulation : characterisation of three genes expressed in proliferating cells
Abstract : Proliferating cells undergo different phases in their life cycle. During interphase the cells grow and duplicate their DNA content, followed by a cell division phase, mitosis, which results in two daughter cells. READ MORE

18. In vitro studies on intestinal epithelial cell proliferation : effects of cytokines, Helicobacter pylori, serotonin and neuroendocrine peptides
Abstract : Previous studies suggest that bacteria and bacterial metabolites, proinflammatory cytokines, neuroendocrine peptides and amines may participate in the regulation of the gastrointestinal-epithelial cell kinetics. The complexity of interactions that take place in vivo makes it difficult to define the primary actions of these and other agents on gastrointestinal cell proliferation. READ MORE

19. The Heterogenic Final Cell Cycle of Retinal Horizontal Cells
Abstract : The cell cycle is a highly complex process that is under the control of several pathways. Failure to regulate and/or complete the cell cycle often leads to cell cycle arrest, which may be followed by programmed cell death (apoptosis). One cell type that has a variety of unique cell cycle properties is the horizontal cell of the chicken retina. READ MORE

20. Cell cycle regulation and DNA damage response : a record of polo-like kinase 1 activity
Abstract : Division and cell proliferation is an essence of life. A human cell has in its core a very simple yet a very complex machinery to coordinate cell cycle activities and events. READ MORE
