    A new study shows that cellular mRNAs can be organized and exported from the nucleus as functionally related groups by RNA-binding proteins, possibly corresponding to specific gene-expression networks activated by transcription factors. The combinatorial assortment of mRNAs as functional subsets has the potential to generate a variety of complex phenotypes from a modest number of genes.

    The focus of research on polycystic kidney disease (PKD) has recently shifted to the primary cilia of renal epithelial cells. A new study shows that the protein products of the genes mutated in PKD mediate mechanosensory calcium mobilization, suggesting that a disruption of fluid-flow sensing triggers abnormal cell proliferation and cyst growth.
