To determine the cellular modifications of endogenous Nm23-H1 and -H2 by oxidative stress, cellular Nm23-H1 was co-purified with Nm23-H2 by immunoprecipitation using Nm23-H1 antibody (Figure 1A) and various PTMs were analyzed using nanoAcquity™ UPLC™/ESI/q-TOF tandem MS as described in methodology.
The next step in a transcriptomic approach would be the simultaneous analysis of viral and cellular modifications of transcription during PrV infection [ 10, 11] using porcine genomic tools.
This leads to numerous cellular modifications (for example, production of reactive oxygen species (ROS), DNA modifications and impairment of membrane permeability) resulting in neuronal apoptosis [ 49].
Metabolic depression may lead to functional cellular modification, post-translational modification of proteins (phosphorylation), and maintenance of homeostasis by ion transport.
Interestingly, these cellular modifications because of the genetic ablation of Hipk2 gave rise to a phenotype characterized by muscle and balance impairment suggesting Hipk2 involvement in cerebellar functions.
Ubiquitylation is one of important cellular modifications and regulates varieties of biological functions, such as cell cycle control, transcriptional regulation, and DNA repair (Hershko and Ciechanover 1998).
Although the mechanism remains unknown at present, it is clear that the product of the gef gene induces cellular modifications that are representative of apoptosis in these tumour cells.
Furthermore, it is unquestionable that an array of cellular modifications [ 8- 13] may contribute to muscle aging, and the pleiotropic nature of muscle aging muscle be recognized and accepted if we are to make significant progress towards its prevention and management.
The ageing process is accompanied by a variety of cellular modifications, and telomere shortening is a common finding.
Among chemicals, solvents are known to induce changes in smell abilities and concomitant histological and cellular modifications related to the type of molecule, concentration and time of exposure.
