TLDR
The mT/mG mouse as mentioned in this paper is a double-fluorescent Cre reporter mouse that expresses membrane-targeted tandem dimer tomato (mT) prior to Cre-mediated excision and membranetargeted green fluorescent protein (mG) after excision.Abstract:
The Cre/loxP system has been used extensively for conditional mutagenesis in mice. Reporters of Cre activity are important for defining the spatial and temporal extent of Cre-mediated recombination. Here we describe mT/mG, a double-fluorescent Cre reporter mouse that expresses membrane-targeted tandem dimer Tomato (mT) prior to Cre-mediated excision and membrane-targeted green fluorescent protein (mG) after excision. We show that reporter expression is nearly ubiquitous, allowing visualization of fluorescent markers in live and fixed samples of all tissues examined. We further demonstrate that mG labeling is Cre-dependent, complementary to mT at single cell resolution, and distinguishable by fluorescence-activated cell sorting. Both membrane-targeted markers outline cell morphology, highlight membrane structures, and permit visualization of fine cellular processes. In addition to serving as a global Cre reporter, the mT/mG mouse may also be used as a tool for lineage tracing, transplantation studies, and analysis of cell morphology in vivo.read more

TL;DR: A set of Cre reporter mice with strong, ubiquitous expression of fluorescent proteins of different spectra is generated and enables direct visualization of fine dendritic structures and axonal projections of the labeled neurons, which is useful in mapping neuronal circuitry, imaging and tracking specific cell populations in vivo.

TL;DR: The authors show that the PHD1 controls muscle mass in a hydroxylation-independent manner and prevents the degradation of leucine sensor LRS during oxygen and amino acid depletion to ensure effective mTORC1 activation in response to leucines.

Coupling of angiogenesis and osteogenesis by a specific vessel subtype in bone
TL;DR: In this paper, the authors identify a new capillary subtype in the murine skeletal system with distinct morphological, molecular and functional properties, which mediate growth of the bone vasculature, generate distinct metabolic and molecular microenvironments, maintain perivascular osteoprogenitors and couple angiogenesis to osteogenesis.

CNS stem cells express a new class of intermediate filament protein.
TL;DR: The predicted amino acid sequence of the nestin gene product shows that nestin defines a distinct sixth class of intermediate filament protein, extending a model in which transitions in intermediate filament gene expression reflect major steps in the pathway of neural differentiation.
