Based on the reactions of other scientists to her work, McClintock felt she risked alienating the scientific mainstream, and from 1953 stopped publishing accounts of her research on controlling elements.
Her work on controlling elements and gene regulation was conceptually difficult and was not immediately understood or accepted by her contemporaries; she described the reception of her research as "puzzlement, even hostility".
Following Jacob and Monod's 1961 Journal of Molecular Biology paper "Genetic regulatory mechanisms in the synthesis of proteins", McClintock wrote an article for American Naturalist comparing the lac operon and her work on controlling elements in maize.
In reference to her decision 20 years earlier to stop publishing detailed accounts of her work on controlling elements, she wrote in 1973: "Over the years I have found that it is difficult if not impossible to bring to consciousness of another person the nature of his tacit assumptions when, by some special experiences, I have been made aware of them.
Details of mammary biopsy, RNA isolation, microarray procedure, primer design and qPCR analysis are found in Additional File 1. Oligonucleotides that were flagged with "-100" by GenePix were removed from the analysis, and the remaining data were normalized to control for dye effects using the median of control elements on the microarray.
We propose a simple but effective implicit-surface-based (ISB) method for constructing composite porous scaffolds (including gradient, hybrid, hierarchical, stochastic porous structures, or their combinations) based on a certain number of control elements (points, line segments, polylines, polygons, etc).
Their conclusion is worth citing at length for it marks a clear break with the tenor of much of the literature on homoeostatic regulation: The attribution of control elements to biological structures always contains the problem of semantic simplification, because the biological structure is reduced to a singular meaning.
The translation of Control elements is more complicated, because they are translated into a transition or a reaction depending on enclosed Control elements.
They may act indirectly through membrane receptors and signal pathways or directly on transcriptional control elements.
Permanent excitation of nerve cells due to the absence of negative regulation is another example of the impact of xenobiotics on one or several control elements of signal transduction.
