A Robust Structural PGN Model for Control of Cell-Cycle Progression Stabilized by Negative Feedbacks
The cell division cycle comprises a sequence of phenomena controlled by a stable and robust genetic network. We applied a probabilistic genetic network (PGN) to construct a hypothetical model with a dynamical behavior displaying the degree of robustness typical of the biological cell cycle. The structure of our PGN model was inspired in well-established biological facts such as the existence of...
متن کاملEstablishing Correspondences between Attribute Spaces and Complex Concept Spaces Using Meta-PGN Classifier
In this paper, we present one approach for extending the learning set of a classification algorithm with additional metadata. It is used as a base for giving appropriate names to found regularities. The analysis of correspondence between connections established in the attribute space and existing links between concepts can be used as a test for creation of an adequate model of the observed worl...
متن کاملConstruction and functional study of pGN, a mammary gland-specific expression plasmid.
The aim of this study was to construct a mammary gland-specific expression vector, pGN, and to validate its function in expressing growth hormone (GH) both in vitro and in vivo. First, the GH gene was amplified and inserted downstream of the b-casein 5'-arm. Next, the neo gene was cloned downstream of the b-casein 3'-arm as a selection marker. To analyze the bioactivity of the pGN plasmid, we e...
متن کاملA two-dimensional population density approach to modeling the dLGN/PGN network
The interaction of two populations of integrate-and-fire-or-burst neurons representing thalamocortical cells from the dorsal lateral geniculate nucleus (dLGN) and thalamic reticular cells from the perigeniculate nucleus (PGN) is studied here using a population density approach. A two-dimensional probability density function that evolves according to a time-dependent advection-reaction equation ...
متن کاملP-37: (+)-Pulegone Reduced Cyp19 GeneExpression and Reduced Leydig CellsSteroidogenic Activity
Background: Pulegone (PGN) is a clear colorless oily liquid, which is widely used in different areas for flavoring foods, drinks, and dental products. There are several reports indicating that the metabolites of the PGN affect cytochrome-P450 family expression and activities. The cytochromes-P450 (cyp19) are involved in Leydig Cells aromatization. Therefore, present study was performed in order...
