Summary MicroRNAs are involved in the control of tumour progression and in metastatic cascade dynamics. However, the role of microRNAs in distant organ reorganization at the premetastatic stage is less clear, although the process of premetastatic niche formation is a crucial event according to modern concepts of tumour dissemination. The role of the present study was to investigate the expression levels of miR‐155, miR‐21, miR‐205 and miR‐let7b, as well as that of their target genes, in target organs of melanoma metastasis at the premetastatic stage. The expression levels of both the pro‐oncogenic miR‐155 and the tumour suppressive miR‐205 were found to be altered in the premetastatic liver of melanoma B16‐bearing mice. Bioinformatics analysis identified the target genes of miR‐155 to be nuclear factor, erythroid 2 like 2 (NFE2L2), secretogranin II, miR‐205, semaphorin 5A and vascular endothelial growth factor A (VEGFA). Among those, the redox status regulatory factor NFE2L2 was downregulated, which corresponded to increased levels of miR‐155. Due to the ability of pro‐oxidative events to initiate angiogenesis, VEGFA levels were evaluated in the premetastatic liver by immunohistochemistry, which revealed increased VEGFA expression in the central parts of the organ and diminished expression in the periphery. Taken together, these findings may support the concept of functional organ reorganization due to melanoma progression.

Background Cancer is a highly complex disease, which involves the cooperation of tumor cells with multiple types of host cells and the extracellular matrix. Cancer studies that rely solely on static measurements of individual cell types are insufficient to dissect this complexity. In the last two decades, intravital microscopy has established itself as a powerful technique that can significantly improve our understanding of cancer by revealing the dynamic interactions governing cancer initiation, progression, and treatment effects in living animals. This review focuses on intravital multiphoton microscopy (IV‐MPM) applications in mouse models of cancer. Recent findings IV‐MPM studies have already enabled a deeper understanding of the complex events occurring in cancer at the molecular, cellular, and tissue levels. Multiple cell types present in different tissues influence cancer cell behavior via activation of distinct signaling pathways. As a result, the boundaries in the field of IV‐MPM are continuously being pushed to provide an integrated comprehension of cancer. We propose that optics, informatics, and cancer (cell) biology are coevolving as a new field. We have identified four emerging themes in this new field. First, new microscopy systems and image processing algorithms are enabling the simultaneous identification of multiple interactions between the tumor cells and the components of the tumor microenvironment. Second, techniques from molecular biology are being exploited to visualize subcellular structures and protein activities within individual cells of interest and relate those to phenotypic decisions, opening the door for “in vivo cell biology”. Third, combining IV‐MPM with additional imaging modalities or omics studies holds promise for linking the cell phenotype to its genotype, metabolic state, or tissue location. Finally, the clinical use of IV‐MPM for analyzing efficacy of anticancer treatments is steadily growing, suggesting a future role of IV‐MPM for personalized medicine. Conclusion IV‐MPM has revolutionized visualization of tumor‐microenvironment interactions in real time. Moving forward, incorporation of novel optics, automated image processing, and omics technologies in the study of cancer biology, will not only advance our understanding of the underlying complexities but will also leverage the unique aspects of IV‐MPM for clinical use.

“…Prior to the formation of overt metastatic disease, DTCs persist in the brain for months or years, and effective engagement with the metastatic niche is essential for colonization and outgrowth (Harper et al, 2016; Hosseini et al, 2016; Massagué and Obenauf, 2016; Sosa et al, 2014 . While the classic 'seed and soil' hypothesis highlights the importance of optimal DTCs arriving in a permissive metastatic microenvironment, recent studies into metastatic seeding, dormany, and outgrowth have revealed dynamic coevolutionary processes between DTCs and the metastatic niche (CeliàTerrassa and Kang, 2018) . Indeed, successful metastatic adaptation requires organspecific interactions with the surrounding parenchymal cells and extracellular matrix (Obenauf and Massagué, 2015) , and the diversity of these interactions (Chen et al, 2016; ContrerasZárate et al, 2019; Er et al, 2018; Schnepp et al, 2017; Zhang et al, 2015 , combined with the evolving heterogeneity of the DTCs themselves, renders the mechanistic dissection required for the development of treatment options challenging.…”

Manuscript Summary:Rab11b upregulation in the brain microenvironment promotes recycling of cargo proteins required for breast cancer brain metastasis, including increased surface expression of integrin β1, which allows brain extracellular matrix attachment and mechanotransduction. Inhibition of the mevalonate pathway with statins prevents geranylgeranylation of Rab11b, decreasing cargo recycling, and inhibiting brain metastasis.

Rab11bmediated control of integrin β1 surface expression allows ligation to the brain ECM, activating mechanotransduction signaling to allow survival and proliferation. We propose a model in which upregulation of Rab11b allows disseminated cells to recycle needed proteins during metastatic adaptation, without strictly requiring transcription and translation, to allow for metastatic outgrowth. 6/10/2019 Rab11b-mediated integrin recycling promotes brain metastatic adaptation and outgrowth -Google Docs https://docs.google.com/document/d/133ky5YwP8HxilKMV1nLO0styFXb_a77AufdN8Q_jytI/edit 3/27 AUTHOR
