Letting Go of the Status Quo: One Program's Experience Discontinuing Ethics Committees and Creating Alternative Structures for Engagement.

AbstractThe authors describe their Ethics Program's transition from utilizing ethics committees to instead implementing a three-initiative structure consisting of Ethics Grand Rounds, an Ethics Liaison Network, and an Ethics Advisory Group. They first outline the history of ethics committees. Then, they discuss the history of their Ethics Program and the challenges that ethics committees posed.

A Novel CRISPR/Cas9-mediated Mouse Model of Colon Carcinogenesis.

Background & Aims: Human sporadic colorectal cancer (CRC) results from a multistep pathway with sequential acquisition of specific genetic mutations in the colorectal epithelium. Modeling CRC in vivo is critical for understanding the tumor microenvironment. To accurately recapitulate human CRC pathogenesis, mouse models must include these multi-step genetic abnormalities.

Bioethics in Gerontology: Developing a Typology of Ethical Issues in Assisted Living.

Assisted living (AL) simultaneously is home to older adults who cannot live independently and a place where people work and visit and, therefore, where value conflicts are apt to arise. In this report we present the "Typology of Ethical Issues in Assisted Living" with emphasis on its development. The typology derives from a synthesis of frameworks used in acute care spaces adapted and applied to data collected as part of an ethnographic study involving AL residents with dementia.

The oncogenic function of PLAGL2 is mediated via ASCL2 and IGF2 and a Wnt-independent mechanism in colorectal cancer.

Colorectal cancer (CRC) tumorigenesis and progression are linked to common oncogenic mutations, especially in the tumor suppressor , whose loss triggers the deregulation of TCF4/β-Catenin activity. CRC tumorigenesis is also driven by multiple epimutational modifiers such as transcriptional regulators. We describe the common (and near-universal) activation of the zinc finger transcription factor and Let-7 target PLAGL2 in CRC and find that it is a key driver of intestinal epithelial transformation.
