AbstractThough the earliest stages of oncogenesis, post initiation, are not well understood, it is generally appreciated that a successful transition from a collection of dysregulated cells to an aggressive tumor requires complex ecological interactions between cancer cells and their environment. One key component of tumorigenesis is immune evasion. To investigate the interplay amongst the ecological behaviour of mutualism and immune evasion, we used a computational simulation framework.

AbstractCancer hallmarks describe key physiological characteristics that distinguish cancers from normal tissues. The temporal order in which these hallmarks appear during cancer pathogenesis is of interest from both evolutionary and clinical perspectives but has not been investigated before. Here, we order hallmarks based on the allele frequency and selective advantage of mutations in cancer hallmark genes across >10k untreated primary tumors and >8K healthy tissues.

1. IntroductionEpiscopic microscopy refers to imaging techniques that utilize serial sectioning and block-face imaging to create high-resolution large-volume three-dimensional (3D) datasets. High Resolution Episcopic Microscopy (HREM) and its associated techniques (namely, Optical HREM, Episcopic fluorescent image capture (EFIC) and multi-fluorescent HREM (MF-HREM) (A)), require samples to be embedded in a supporting material to enable automated sectioning at the micron scale.
