From a systems perspective, these differential activities present themselves as an enhancement of

complexity [6]. Their presenting character turns out to be primarily communicative, as shown in the methodological discussion. Communication-technical considerations will be helpful LBH589 clinical trial to uncover mechanisms of action of modularly designed therapy approaches and to conceptualize how this novel way of treatment modulates sub-cellular and cellular communication. At first, these considerations involve a theory relating to communicative aspects of socially linked cell communities, such as the tumor compartment. The theory is also supported by observations derived from a unique pattern of modular therapies administered in a broad variety of metastatic tumors [6]. This

theory leads to the question how communication processes may be initiated (therapeutic aspect) in the context of the basic components of the communicative ‘metabolism’, which foster natural or therapeutically adjoined but implicitly evolutionary-linked tumor development. Induction of novel validity in informative cellular or intercellular communication processes by modular events may be an important mechanism promoting tumor evolution or treatment. Methods: A Formal-Pragmatic Communication Theory Clinical results used to support the formal-pragmatic communication theory refer to recently published data [6]. Definition of the Tumor’s Living World as a Holistic

Communicative Unit Exemplarily for cellular Vistusertib datasheet transcription www.selleckchem.com/products/Cyt387.html factors, their context-dependent and cell type-specific transcriptional activity illustrates the meaning of the term modularity. The activity is mirrored on a cellular level by the multi-functionality of, for instance, macrophages Sitaxentan or fibroblasts. Modularity in the present context is a formal-pragmatic communicative systems concept, describing the degree and specificity to which systems’ objects (cells, pathways, molecules, e.g. transcription factors, etc.) may be communicatively separated in a virtual continuum, reassembled and rededicated (e.g. co-option) to alter validity and denotation of communication processes. This concept refers to possible interactions between the systems objects in a tumor as well to the degree to which the communicative rules of the systems architecture (for establishing validity and denotation) enable or prohibit the focus on validity and denotation. Systems objects acquire the features of symbols, which are rich in content and which are able to acquire novel references by rearranging validity and, consecutively, denotation. Tumors consist of modules, which become a scientific object by communicatively uncovering the tumor’s living world (defined as the tumor’s holistic communicative world) with biomodulatory and therefore modularly designed events (for instance biomodulatory therapies).
