This framework, although using classic probabilistic expressions, offers a novel view of the calculations used in the IMPACT model.
What ever the process, it seems likely that epigenetic changes regulating gene expression offer a more rapid means by which tumour cells can adapt to new environment such as cytotoxic drug therapy than genetic change and because such changes are heritable they can be passed on to daughter cells without the need for continuous selection pressure producing persistent acquired resistance.
In addition, the c-Fos gene is expressed following noxious input, and level of expression offers a marker of signals to sensory cells in the spinal cord [ 2- 4].

Given the importance of phytochromes in key plant developmental processes, genetically manipulating phytochrome expression offers a promising approach to crop improvement.
Sevigny has a pitiless quality (as evidenced in her recent complaint that Manchester was the grimmest place she had ever been) that must be a help if you're a killing machine, and her trademark bruised expression offered a fair enough sense of a woman with a past.
Overall these results indicate that E. coli expression offers a practical platform for the reproducible production of fully biologically active E5/K5-coil-tagged EGF, and support applications of heterodimerizing coil-tagged ligands, e.g. the targeting of viruses or other entities such as nanoparticles to tumor cells, or growth factor immobilization on cell culture scaffolds for tissue engineering.
SAGE (serial analysis of gene expression) offers a sequence-based, non-biased approach to comprehensive transcriptome analysis, with no prior knowledge of expression required [18].
Differential gene expression offers a viable window into the complexity of the cellular response to deviation from normal activity and to drug treatment.
Fluorescent protein expression offers a static view based on differential transcriptional activity between neuronal populations but eGFP expression can also be used as a sensor of neuronal ensemble and immediate-early promoter activity [27].
