    <i>Introduction</i>: Mutations affecting p53 or its upstream activator Chk2 are associated with resistance to DNA-damaging chemotherapy in breast cancer. ATM (Ataxia Telangiectasia Mutated protein) is the key activator of p53 and Chk2 in response to genotoxic stress. Here, we sought to evaluate ATM's potential role in resistance to chemotherapy.<p> <p><i>Methods</i>: We sequenced <i>ATM</i> and ...
  • No evidence that portion size influences food consumption in male Sprague Dawley rats 

    Naneix, Fabien; Pinder, Sophie C.; Summers, Megan Y.; Rouleau, Renee M.; Robinson, Eric; Myers, Kevin P.; McCutcheon, James E. (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-04-18)
    In studies of eating behavior that have been conducted in humans, the tendency to consume more when given larger portions of food, known as the portion size effect (PSE), is one of the most robust and widely replicated findings. Despite this, the mechanisms that underpin it are still unknown. In particular, it is unclear whether the PSE arises from higher-order social and cognitive processes that ...
