Prostate apoptosis response-4 and tumor suppression: it’s not just about apoptosis anymore
The tumor suppressor prostate apoptosis response-4 (Par-4) has recently turned ‘twenty-five’. Beyond its indisputable role as an apoptosis inducer, an increasing and sometimes bewildering, new roles for Par-4 are being reported.

The Many Hats of Sonic Hedgehog Signaling in Nervous System Development and Disease. [PDF]
Sonic hedgehog (Shh) signaling occurs concurrently with the many processes that constitute nervous system development. Although Shh is mostly known for its proliferative and morphogenic action through its effects on neural stem cells and progenitors, it ...

Systematic analysis of the intersection of disease mutations with protein modifications
Background Perturbed posttranslational modification (PTM) landscapes commonly cause pathological phenotypes. The Cancer Genome Atlas (TCGA) project profiles thousands of tumors allowing the identification of spontaneous cancer-driving mutations, while ...

Cell–cell signalling: Frog frizbees [PDF]
The recent discovery that Frizzled proteins are receptor for Wnts has been quickly followed by the identification of a secreted protein, Frzb, that is related to Frizzled, expressed by the Spemann organizer in frog embryos and can bind to and antagonize Wnt developmental signalling molecules.

CRISPR/Cas9-based editing of a sensitive transcriptional regulatory element to achieve cell type-specific knockdown of the NEMO scaffold protein [PDF]
The use of alternative promoters for the cell type-specific expression of a given mRNA/protein is a common cell strategy. NEMO is a scaffold protein required for canonical NF-κB signaling.

Direct control of lysosomal catabolic activity by mTORC1 through regulation of V-ATPase assembly
mTORC1 blocks lysosomal nutrient generation. Here, the authors show that mTORC1 inactivation triggers V-ATPase assembly, which rapidly initiates lysosomal acidification and degradation of protein contents throughout the lysosomal population.

SUMOylation and cell signalling
AbstractSUMOylation is a highly transient post‐translational protein modification. Attachment of SUMO to target proteins occurs via a number of specific activating and ligating enzymes that form the SUMO‐substrate complex, and other SUMO‐specific proteases that cleave the covalent bond, thus leaving both SUMO and target protein free for the next round ...

Cells experience various osmotic perturbation, but cellular osmosensing mechanisms remain obscure. Here, the authors report that cells recognize osmotic stress from the inside through macromolecular crowding-driven and poly(ADP-ribose)-conditioned liquid–

Alternative cell death pathways and cell metabolism [PDF]
While necroptosis has for long been viewed as an accidental mode of cell death triggered by physical or chemical damage, it has become clear over the last years that necroptosis can also represent a programmed form of cell death in mammalian cells.
