When plants perceive stress signals from their surroundings, a number of physiological, biochemical and molecular modifications occur (Krasensky and Jonak 2012).
At a molecular level, modifications occurring from chemical reactions between the fixative and nucleic acids may cause nucleic acid fragmentation and degradation of the RNA [ 7].
We move from a structural overview to the broad cellular and synaptic context of neuroligins, intermolecular interactions, and molecular modifications that occur within a synapse.
Molecular mechanisms involved in Gli1 and Gli2 function have so far addressed specific residues affected by post-translational modifications occurring outside the DNA binding domain.
The expression of TNF-α is regulated in a complex network of molecular events, wherein epigenetic modifications occur both developmentally and in response to acute stimulation (Lee et al. 2003; Sullivan et al. 2007).
In vitro models have been widely used to identify the specific functions of the endothelium and to understand the molecular modifications that might occur during angiogenesis.
The widely used size-based criteria have increasingly become inadequate where early measures of response are required to avoid toxicity of ineffective treatments, as biological, physiologic, and molecular modifications in tumours occur before changes in gross tumour size.
A disease outcome likely results from aberrant activity of many different molecular pathways, and thus it is likely that epigenetic modifications occur at multiple genes or genic regions.
We are unable to identify the precise role of each modification because all the modifications occurred at the same time.
What's more, over two-thirds of modifications occur outside of the program.
Often different post-translational modifications occur in tandem, and the cross talk between these modifications determines the final cellular outcome.
