The Pentagon is undergoing what Mr. Rumsfeld has called a process of transformation, reviewing the location and size of its bases and the numbers of troops deployed overseas to incorporate improvements in the ability to gather intelligence, target weapons and field forces quickly.
The enhanced photochemical activity of these highly structured composites can be utilized in many fields of optoelectronics like environmental remediation, water splitting, CO2 photoreduction and selective organic transformation, reviewed, e.g. in [69].
This is exemplified by the observations that human embryonic stem cells have specific epigenetic signatures [12] [14], many tissue-specific genes present promoter DNA methylation-dependent regulation (reviewed in [15], [16]), and finally, aberrant hypermethylation-mediated repression of genes involved in cell differentiation results in malignant transformation (reviewed in [17], [18]).
Myc proteins regulate normal proliferation, cell growth, and apoptosis, cellular functions aberrantly regulated by excess Myc during malignant transformation (reviewed in [ 13]).
The morphological correlate manifests as loss of cell polarity towards spindle-shaped transformation (reviewed in Thiery, 2002; Thiery et al, 2009; Lim and Thiery, 2012).
This generalized genetic instability is thought to lead to the accumulation of additional mutations that eventually allow Brca1-deficient cells to undergo neoplastic transformation (reviewed in [ 2]).
Despite its many shortcomings, continuous cell culture remains the most common model system for investigating molecular mechanisms of normal differentiation, disease, and neoplastic transformation (reviewed in [ 1]).
Since AML1 is required for differentiation of haematopoietic cells, AML1 ETO expression leads to a block in myeloid development and leukaemic transformation (reviewed in Jones and Saha, 2002).
Disorganisation of the actin cytoskeleton is a characteristic feature of transformation (reviewed in Pawlak and Helfman, 2001) and the potential to reinstate normal cytoskeletal structure and function represents a promising target for cancer therapy.
Even though the mechanisms by which the virus engenders disease are not yet completely understood, numerous evidences indicate the multifunctional Tax protein as essential for malignant transformation (reviewed in [ 9]).
