Intracellular membrane trafficking is essential for organelle biogenesis, structure, and function; the exchange of material between organelles; and communication between the cell and its external environment. Genetic disorders affecting intracellular trafficking can lead to a variety of human diseases, but specific therapies for these diseases are notably lacking. In this article, we focus on how current knowledge about genetic disorders that affect intracellular trafficking can be used to develop strategies for cell-based assays in order to identify drugs using high-content screening approaches...

Reprogramming somatic cells to derive induced pluripotent stem cells (iPSCs) has provided a new method to model disease and holds great promise for regenerative medicine. Although genetically identical to their donor somatic cells, iPSCs undergo substantial changes in the epigenetic landscape during reprogramming. One such epigenetic process, X chromosome inactivation (XCI), has recently been shown to vary widely in human female iPSCs and embryonic stem cells (ESCs). XCI is a form of dosage compensation whose chief regulator is the noncoding RNA Xist...
