For deeper mechanistic insights, SPARK Microgravity can integrate -omics analyses into your microgravity study. Our -omics data packages (genomics, transcriptomics, proteomics, or metabolomics) examine how the spaceflight environment influences molecular profiles. After the completion of an experiment on the ISS, we either preserve samples in-flight or immediately upon return and process them following strict GCP/GLP-compliant protocols. Whether it’s RNA sequencing to spot gene expression changes or proteomic profiling to see pathway activation, these datasets can identify biomarkers and targets affected by microgravity. Such knowledge is invaluable for understanding drug mechanisms or stress responses. For instance, highlighting pathways that are up- or down-regulated when cancer cells grow in microgravity. All -omics results are delivered with rigorous bioinformatic analysis and can be correlated with phenotypic outcomes for a comprehensive insight.
The -omics service helps you if your drug worked and why and how to make it better.
The -omics service delivers actionable insights that go far beyond a typical assay. It’s about turning data into knowledge: you don’t just learn if your drug worked, you learn why and how to make it better. By revealing the molecular underpinnings of tumor response, you gain a competitive edge – proprietary knowledge of pathways and biomarkers that others might miss. It also provides a form of risk insurance: with comprehensive data in hand, you can justify decisions to halt a program or advance it with confidence, backed by evidence that resonates with scientific and financial stakeholders. In short, you get a 360° view of your therapeutic’s impact, which is invaluable in making informed, successful development decisions.
Early studies have made striking discoveries through such -omics analyses. For instance, a 2024 study on colorectal cancer organoids found that microgravity induced significant changes in gene expression: it dysregulated an entire family of genes (TBC1D3) and upregulated cell-cycle processes, correlating with the organoids’ faster growth and heightened sensitivity to chemotherapy1. This same study’s drug screen showed an enhanced response to 5-FU (a common chemo drug) under microgravity – a clue that gravity affects drug potency at the molecular level2.
In one organoid line, key histone genes and modifiers were almost completely silenced in orbit3. Such a dramatic loss of certain histone gene expression (coupled with downregulation of chromatin regulators KMT2C/D/E) suggests that weightlessness alters chromatin structure and gene regulation in ways not seen at 1g. These discoveries are only possible by taking a deep -omics dive. By comparing microgravity vs. Earth samples, scientists have also identified activation of stress pathways and DNA repair mechanisms unique to microgravity exposure.
For example, a tumor organoid might express different markers and fall into a different transcriptomic category under microgravity4, indicating a change in its biology. Perhaps towards a more aggressive or more drug-sensitive state. All of this rich information comes from -omics data.
In summary, systematically analyzing gene and protein changes has revealed why microgravity-grown tumors often show different growth or drug responses. It unearths new mechanisms (like altered apoptosis signaling or cytoskeletal gene changes) and highlights potential therapeutic targets. For example, if microgravity makes the tumor heavily rely on a certain survival pathway, that pathway could be a drug target on Earth. Each genomic or proteomic discovery adds to our understanding of cancer’s “gravity context,” and guides developers in crafting better strategies, such as combination therapies to exploit microgravity-vulnerable pathways.
The -omics outputs from microgravity-cultured tumors closely resemble what we get from actual patient tumor analyses. You can expect data sets such as RNA sequencing results, proteomic profiles, or even metabolomic readouts that capture the tumor’s internal state. What makes it “in vivo-like” is the complexity and relevance of the patterns.
For example, you may find that the gene expression profile of a microgravity-grown organoid aligns with a known clinical subtype of that cancer. In one study, researchers noted a shift in the consensus molecular subtype (CMS) of a colorectal tumor organoid under microgravity6 meaning the gravity-free environment pushed the organoid’s gene profile closer to what’s seen in aggressive tumors in patients. These kinds of comprehensive data tell you not just one or two markers, but thousands of genes and how their expression interrelates.
You’ll see pathway enrichment analyses: data might show that G2M cell-cycle checkpoints and mitotic pathways are significantly enriched under microgravity (which was reported in the colorectal organoids study)7, much like rapidly proliferating tumors in patients. If your drug was applied, you’ll get a read on how the tumor’s biology reacted – did it upregulate stress genes? induce apoptosis genes?
Such multi-dimensional data is analogous to taking a biopsy from a patient’s tumor before and after treatment and doing whole-genome profiling. Additionally, the noise and variability in these data reflect real-world biology: microgravity organoids have heterogeneous cell populations (like real tumors), so your -omics data will show a mixture of signals from perhaps cancer stem-like cells vs. differentiated cells, etc., rather than the overly uniform (and less clinically relevant) signals from 2D cell lines.
In practical terms, expect to receive a detailed report listing significantly changed genes, key pathways activated or suppressed, heatmaps comparing conditions, and possibly correlations to known databases . For instance, matching the organoid’s gene signature to thousands of patient samples to see what it most closely resembles. This can mirror an in vivo scenario where you’d do genomic profiling to guide therapy, except here you’re doing it in a preclinical experiment, saving time and guiding decisions before you ever go to trial.
Harnessing -omics data in microgravity matters on multiple levels.
By understanding the full molecular impact of a drug, companies can avoid late-stage failures. For example, if -omics data reveals your drug isn’t hitting its target pathway (or the tumor is compensating by activating an alternative pathway), you can course-correct early – perhaps by modifying the drug, adjusting the dose, or adding a combo agent. This can save enormous costs and time that would have been spent on a likely-failing strategy.
The dream of giving the right drug to the right patient hinges on knowing molecular markers of response. Microgravity -omics can identify those markers under highly realistic conditions. This means when your drug moves to clinical trials, you could include a companion diagnostic (based on a gene signature, for instance) to select patients who are most likely to respond, improving trial success rates.
The data generated can lead to new hypotheses and spin-off projects. Discovering that, say, microgravity suppresses a tumor’s DNA repair genes might suggest a vulnerability – perhaps on Earth, combining a DNA-damaging agent with a microgravity-mimicking inhibitor could be a novel therapy. In essence, you might find entirely new ways to kill cancer by studying how gravity absence stresses the cells. Many researchers view microgravity as a “black box” that, when opened with -omics, could reveal fundamental truths about cancer biology.
In the eyes of investors, partners, or regulatory agencies, having hard data on mechanisms can be very persuasive. Rather than just saying “our drug shrank an organoid,” you can show how it reprogrammed the tumor’s gene expression. For example, “it downregulated these oncogenes and activated immune pathways”. This level of detail demonstrates a deep understanding of your product and can expedite discussions with the FDA or grant funders by answering questions proactively. Overall, -omics data packages ensure you’re not operating in the dark. The -omics data packages illuminate the molecular story behind efficacy or failure, which is ultimately why drugs succeed or fail in patients.
