Proteomics is evolving as a multi-faceted tool for addressing various biochemical and biomedical queries in the field of scientific research. This involves various stages, ranging from sample preparation to data analysis and biological interpretation. Sample preparation involves isolating proteins from the sample source, purifying and digesting them to initiate shotgun proteomics. Shotgun proteomics identifies proteins by bottom-up proteomic approaches where proteins are identified from the fragmentation spectra of their own peptides. Paper I: deals with the simplification of functional characterization for nanoparticles intended for use in biomedicine. Proteomics was constructive in differentiating and semi-quantifying the surface of protein corona. This could be beneficial in predicting the interactions between nanoparticles and a biological entity like the cell or a receptor protein and provide initial valuable information related to targeting, uptake and safety. Paper II: deals with understanding effects of TiO2 nanoparticles on endothelial cells. A combinatorial approach, involving transcriptomics and proteomics was used to identify aberrations in the permeability and integrity of endothelial cells and tissues. Our study also investigated the correlation of size and how they motivated a differential cellular response. In case of intravenous entry for nanoparticles in targeted drug delivery systems, endothelial cells are the first barrier encountered by these drug carriers. This evaluation involving endothelial cell response could be very instrumental during the designing of NP based drug delivery systems. Paper III: Pharmaceuticals and its metabolites could be very hazardous, especially if its disposal is not managed properly. Since water bodies are the ultimate sink, these chemicals could end up there, culminating in toxicity and other ‘mixture effects’ in combination with other factors. To evaluate the effects of the pharmaceutical, propranolol and climatic factors like low salinity conditions, a microcosm exposure was designed and shotgun proteomics helped understand its impact on mussel gills. In this study too, a combination of transcriptomics and proteomics unveiled molecular mechanisms altered in response to stressors, both individually and in combination. Paper IV: An interplay of various factors like EBF1 and PAX5 determines B-cell lineage and commitment. This might have been materialized by direct and transient proteinprotein interactions. A unique method called BioID helped screen relevant interactions in living cells by the application of a promiscuous biotin ligase enzyme capable of tagging proteins through biotinylation based on a proximity radius. Biotinylation of endogenous proteins enabled their selective isolation by exploiting the high affinity of biotin and streptavidin on streptavidin coated agarose beads, leading to their identification by mass spectrometry. The biotinylated proteins were potential candidate interactors of EBF1 and PAX5, which were later confirmed by sequencing techniques like ChIP-Seq, ATAC seq, and visualization techniques like proximity ligation assay (PLA).

This book concisely describes the role of omics in precision medicine for cancer therapies. It outlines our current understanding of cancer genomics, shares insights into the process of oncogenesis, and discusses emerging technologies and clinical applications of cancer genomics in prognosis and precision-medicine treatment strategies. It then elaborates on recent advances concerning transcriptomics and translational genomics in cancer diagnosis, clinical applications, and personalized medicine in oncology. Importantly, it also explains the importance of high-performance analytics, predictive modeling, and system biology in cancer research. Lastly, the book discusses current and potential future applications of pharmacogenomics in clinical cancer therapy and cancer drug development.

Technologies collectively called omics enable simultaneous measurement of an enormous number of biomolecules; for example, genomics investigates thousands of DNA sequences, and proteomics examines large numbers of proteins. Scientists are using these technologies to develop innovative tests to detect disease and to predict a patient's likelihood of responding to specific drugs. Following a recent case involving premature use of omics-based tests in cancer clinical trials at Duke University, the NCI requested that the IOM establish a committee to recommend ways to strengthen omics-based test development and evaluation. This report identifies best practices to enhance development, evaluation, and translation of omics-based tests while simultaneously reinforcing steps to ensure that these tests are appropriately assessed for scientific validity before they are used to guide patient treatment in clinical trials.

Salivary Diagnostics surveys one of the most exciting areas of research in oral biology. Regarded as the mirror of the body, saliva has immense potential to yield real clinical improvements in our ability to diagnose, and hence treat, oral and systemic conditions. The composition of saliva and other oral fluids reflects the tissue fluid levels of therapeutic, hormonal, and immunological molecules, as well as the presence of markers for systemic and oral disease.
