NRAS is unique among RAS proteins in requiring ICMT for trafficking to the plasma membraneAmong the RAS isoforms, NRAS uniquely requires carboxyl methylation by ICMT for delivery to the plasma membrane because of having only a single palmitoylation as a second targeting signal.
Modulating HSF1 levels impacts expression of the estrogen receptor α and antiestrogen responseThis work shows that activation of the main cellular stress response pathway is responsible for antiestrogen resistance in breast cancer, a process that is reversible.
A systems-based method to repurpose marketed therapeutics for antiviral use: a SARS-CoV-2 case studyThis study describes complementary network-based and sequence similarity methods to identify drug repurposing opportunities predicted to directly target viral proteins, highlighting results for five human pathogens.
Renal CD169++ resident macrophages are crucial for protection against acute systemic candidiasisA renal CD169++ resident macrophage subpopulation controls Candida albicans growth, severe kidney inflammation, and immunopathology during acute systemic candidiasis.
GATA transcription factors, SOX17 and TFAP2C, drive the human germ-cell specification programThis work shows that GATA transcription factors transduce the BMP signaling and, with SOX17 and TFAP2C, induce the human germ-cell fate, delineating the mechanism for human germ-cell specification.
nNOS regulates ciliated cell polarity, ciliary beat frequency, and directional flow in mouse tracheaDirectional flow of mucus across the mucociliary epithelium enables the clearance of the airway. This study shows that nNOS supports the flow by regulating the planar polarity and ciliary beat frequency of ciliated cells in the tracheal epithelium.
The Wnt signaling receptor Fzd9 is essential for Myc-driven tumorigenesis in pancreatic isletsZacarías-Fluck, et al identify and validate the Wnt receptor Fzd9 as a key effector of Myc-Wnt signaling cross-talk in a mouse model of Myc-driven pancreatic insulinomas.
Kalirin-RAC controls nucleokinetic migration in ADRN-type neuroblastomaVideo and gene expression analyses coupled with the RNAi technique reveal microtubule-dependent, neuronal-like nucleokinetic migration in a noradrenergic type of neuroblastoma, providing a glimpse into the mechanism by which noradrenergic neuroblastoma cells may spread.
