The metabolism of cyclopropane fatty acids by Tetrahymena pyriformis.
Cyclopropane fatty acids are readily metabolized by whole cells of Tetrahymena pyriformis when the fatty acids are presented either as components of intact Escherichia coli cells or as free fatty acids added to the medium. cis-ll,lZ[methylene-14C]Methyleneoctadecanoic acid was degraded with the production of 14COz by whole T. pyriformis cells or a particulate fraction derived from them. In the ...
متن کاملThe Fine Structure of the Nuclei of Tetrahymena Pyriformis throughout the Cell Cycle
The fine structure of the nuclei of logarithmically growing Tetrahymena pyriformis, strain HSM, was studied at 30-minute intervals throughout the cell cycle. Organisms were selected at similar stages of cytokinesis by means of a braking pipette, incubated, fixed in OsO(4), and embedded in agar to facilitate subsequent preparation for electron microscopy. Aggregates of micronuclear chromatin und...
متن کاملControl of tubulin and actin gene expression in Tetrahymena pyriformis during the cell cycle.
Poly(A)-containing mRNA was isolated from division synchronized populations of the ciliated protozoan, Tetrahymena pyriformis. The level of tubulin and actin mRNA at specific cell cycle stages was analyzed by hybridization to tubulin and actin cDNA probes and by gel analysis of their in vitro translation products. The pattern of fluctuation of tubulin mRNA levels was similar to that observed fo...
متن کاملA Modular Model of Cyclic AMP Signaling in Yeast: Linking Cell Cycle Progression and Energy Metabolism
The pursuit of a systems-level understanding of biological processes constitutes one of the central goals of systems biology. In this work, a combination of experimental techniques and mathematical modeling has been applied to analyze the impact of signal transduction via the second messenger cyclic AMP (cAMP) on the coordination of energy metabolism and cell cycle progression in the yeast Sacc...
متن کاملCyclic AMP, a nonessential regulator of the cell cycle.
Flow-microfluorimetric analysis has been carried out on populations of exponentially growing S49 mouse lymphoma cells treated with dibutyryl cyclic AMP. The drug produces a specific concentration-dependent block in the G-1 phase of the cell cycle while other phases of the cycle are not perceptibly altered. The cell cycle of a line of mutant cells lacking the cyclic AMP-dependent protein kinase ...
