On the other hand, there is an inherent difficulty in defining DNA segments and their variants that can be qualified as regulatory in contrast, for example, to easily qualifiable alterations in the protein-coding sequences.
For example, to construct a genome alteration print, Popova et al. (2009) require a good segmentation algorithm: 'the absence of true breakpoints could significantly alter the GAP pattern'.
For example, to our knowledge apparent epigenetic alterations have not been observed in either AtCTF7 RNAi or atctf7 plants [ 17, 18].
This lack of an energetic barrier for Zn II) may be important for its catalytic properties, allowing for changes in coordination number throughout the catalytic cycle (from four- to five-coordinate, for example, to accommodate the intermediate) and for alterations in the reactivity of the metal ion.
While we do not know to what extent the evolution of resistance to specific treatments may occur in cancer prevention, as mentioned above, there is a risk that aggressive metastatic mutants may be selected by low-dose preventive therapies, for example, due to alteration of the microenvironment (Albini and Sporn 2011).
For example, alterations to fibroblasts adjacent to the transformed epithelium involve proliferation, growth factor expression and even local estrogen production.
Nonetheless, it remains to be determined whether B-cell superantigens (for example, staphylococcal protein A, staphylococcal enterotoxin D) [ 24] might play a role in GPA, which, for example, would lead to alterations in the Ig V gene repertoire of B cells.
Color changes, for example, are due to alterations in chlorophyll, carotenoid and other pigment content of the plastids and vacuoles [ 5- 7].
The catalog of Notch ICD mutations generated by our analysis of the CCLE data base provides an opportunity to functionally characterize the effects of these mutations, for example with regard to alterations in signaling strength [ 46], intracellular routing [ 47] or the ability to intersect with other signaling mechanisms [ 6].
Minor modifications to the setup would allow for automatic dual wavelength operation, for example shot-to-shot alteration.
