Environmental insults and compensative responses: when microbiome meets cancer

AbstractTumor microenvironment has recently been ascribed a new hallmark —the polymorphic microbiome. Accumulating evidence regarding the tissue specific territories of tumor-microbiome have opened new and interesting avenues. A pertinent question is regarding the functional consequence of the interface between host-microbiome and cancer. Given microbial communities ha ve predominantly been explored through an ecological perspective, it is important that the foundational aspects of ecological stress and the fight to ‘survive and thrive’ are accounted for tumor-micro(b)environment as well. Building on existing evidence and classical microbial ecology, here we a ttempt to characterize the ecological stresses and the compensative responses of the microorganisms inside the tumor microenvironment. What insults would microbes experience inside the cancer jungle? How would they respond to these insults? How the interplay of stress and microbial quest for surviva l would influence the fate of tumor? This work asks these questions and tries to describe this underdiscussed ecological interface of the tumor and its microbiota. It is hoped that a larger scientific thought on the importance of microbial competition sensing vis-à-vis tumor-microenvironment would be stimulated.
