요약Tumorigenesis hinges on the reprogramming of cellular metabolism, a consequence of oncogenic mutations both directly and indirectly. Cancer cell metabolism, characterized by its adeptness at extracting essential nutrients from nutrient-deficient environments, profoundly influences gene expression, cellular differentiation, and the tumor microenvironment. Consequently, understanding the adaptive metabolic processes of cancer cells is crucial for deciphering their rapid growth. Metabolomics profiling emerges as a potent tool, capable of monitoring changes in tumor metabolism, assessing treatment response, predicting individual metabolic shifts in response to cancer therapy, measuring medication efficacy, and tracking drug resistance.We examined reported volatiles in cell cultures of lung cancer to better understand the origins of cancer-associated VOCs and highlight the metabolic processes of lung cancer that could be responsible for the endogenous synthesis of these VOCs and pinpoint the protein-encoding genes involved in these pathways. We then employed a novel ionization technique, secondary electrospray ionization (SESI) coupled to a high-resolution mass spectrometer (HRMS), for the rapid and online analysis of cancer derived volatiles in-vitro. In the context of lung cancer, we identified 60 significant volatile organic compounds (VOCs) associated with cancer cells, distinguishing between non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) through partial least squares-discriminant analysis (PLS-DA). Our work also suggested unique chemical composition of in-vitro headspace profiles, when lung cancer cells are treated with drug.While SESI-HRMS analyses are innovative analytical techniques, the nature of this ionization renders data collection susceptible to ion competition. To address challenges, we developed a novel pseudo-targeted approach, database-assisted globally optimized targeted (dGOT)-SESI-HRMS, using the microbial-VOC (mVOC) database and spectral stitching methods. This approach, validated with anaerobic bacterial cultures, successfully identified 109 VOCs, with 88 confirmed as culture-derived volatiles. Annotation was also achieved with a total of 25 unique volatiles referenced to standard databases allowing for biological interpretation. Successful development of this VOC analysis method enabled robust analysis of the volatilome associated with distinct interventions in mice. Subsequent analyses uncovered unique volatile profile of mice with unique microbiome composition as well as cancer, when compared to WT mice, respectively. Our data corroborated reports that the systemic metabolic alterations dictated between the microbiome and the host, or disease state translate to changes in the volatilome.Additionally, metabolomics serves as a powerful analytical tool to survey metabolism. We employed two unbiased high-throughput techniques to uncover metabolic deregulations associated with acquired ibrutinib resistance in lymphoma. Integration of the data uncovered genetic perturbations and identified key players, such as IL4I1, influencing metabolic reprogramming in the drug-resistant lymphomas. This comprehensive approach underscores the power of metabolomics for revealing systemic metabolic and volatile changes associated with cancer cells.
