Integrating different types of data, including electronic health records, imaging data, administrative and claims databases, large data repositories, the Internet of Things, genomics, and other omics data, is both a challenge and an opportunity that must be tackled head on. We explore some of the challenges and opportunities in optimizing data integration to accelerate breast cancer discovery and improve patient outcomes. Susan G.

In January 2016, the Metastatic Breast Cancer Alliance (the Alliance) convened a think tank of stakeholders from academia, government, industry, and patient advocacy to discuss gaps and opportunities in clinical and translational research in metastatic breast cancer. Priorities that emerged from the meeting included the following: the need for innovative preclinical model systems to study metastatic disease; increased sharing of resources and data; collaboration across cancer care teams and scientists; biorepositories for studies to identify biomarkers for treatment response; creation of patient registries to increase access to clinical trials and tissue procurement; and redesign of clinical trials in metastatic breast cancer. .

In addition to its well described function as an enzymatic inhibitor of specific caspases, X-linked inhibitor of apoptosis (X-linked IAP or XIAP) can function as a cofactor in Smad, NF-kappaB, and JNK signaling pathways. However, caspases themselves have been shown to regulate the activity of a number of signaling cascades, raising the possibility that the effect of XIAP in these pathways is indirect. Here we examine this question by introducing point mutations in XIAP predicted to disrupt the ability of the molecule to bind to and inhibit caspases.

We have studied the effects of two new synthetic triterpenoids, 2-cyano-3,12-dioxooleana-1,9-dien-28-oic acid (CDDO) and its derivative, 1-(2-cyano-3,12-dioxooleana-1,9-dien-28-oyl) imidazole (CDDO-Im), on transforming growth factor (TGF)-beta/Smad signaling. These agents, at nanomolar concentrations, increase the expression of TGF-beta-dependent genes, such as those for plasminogen activator inhibitor 1 and the type II TGF-beta receptor, and they synergize with TGF-beta in this regard. They prolong the activation of Smad2 induced by TGF-beta and markedly enhance the ability of Smad3 to activate a Smad binding element, CAGA-luciferase.
