TL;DR: Reduction of endothelial miRNAs by cell-specific inactivation of Dicer reduces postnatal angiogenic response to a variety of stimuli, including exogenous VEGF, tumors, limb ischemia, and wound healing.
Abstract: Posttranscriptional gene regulation by microRNAs (miRNAs) is important for many aspects of development, homeostasis, and disease. Here, we show that reduction of endothelial miRNAs by cell-specific inactivation of Dicer, the terminal endonuclease responsible for the generation of miRNAs, reduces postnatal angiogenic response to a variety of stimuli, including exogenous VEGF, tumors, limb ischemia, and wound healing. Furthermore, VEGF regulated the expression of several miRNAs, including the up-regulation of components of the c-Myc oncogenic cluster miR-17-92. Transfection of endothelial cells with components of the miR-17-92 cluster, induced by VEGF treatment, rescued the induced expression of thrombospondin-1 and the defect in endothelial cell proliferation and morphogenesis initiated by the loss of Dicer. Thus, endothelial miRNAs regulate postnatal angiogenesis and VEGF induces the expression of miRNAs implicated in the regulation of an integrated angiogenic response.

TL;DR: It is found that both Cry1 and Cry2 proteins are ubiquitinated and degraded via the SCFFbxl3 ubiquitin ligase complex, a prerequisite for the efficient and timely reactivation of Clock-Bmal1 and the consequent expression of Per1 and Per2, two regulators of the circadian clock that display tumor suppressor activity.
Abstract: One component of the circadian clock in mammals is the Clock-Bmal1 heterodimeric transcription factor. Among its downstream targets, two genes, Cry1 and Cry2, encode inhibitors of the Clock-Bmal1 complex that establish a negative-feedback loop. We found that both Cry1 and Cry2 proteins are ubiquitinated and degraded via the SCF(Fbxl3) ubiquitin ligase complex. This regulation by SCF(Fbxl3) is a prerequisite for the efficient and timely reactivation of Clock-Bmal1 and the consequent expression of Per1 and Per2, two regulators of the circadian clock that display tumor suppressor activity. Silencing of Fbxl3 produced no effect in Cry1-/-;Cry2-/- cells, which shows that Fbxl3 controls clock oscillations by mediating the degradation of CRY proteins.

TL;DR: In every diagnostic group, a highly significant correlation was found between total tau and phospho-tau (Alzheimer's disease, r(2)=0.73; frontotemporal dementia, r (2)=0.42), suggesting that the degree of phosphorylation of CSF-t Tau changes in different clinical conditions.

TL;DR: The 10-year results of a controlled trial of a policy of surgery and a strategy of radical radiotherapy in the treatment of patients with small-cell or oat-celled carcinoma of the bronchus diagnosed preoperatively on bronchial biopsy and thought likely to be operable were given in this paper.

TL;DR: The data presented here extend the definition of the human microbiome by providing a more complete and accurate picture of human microbiome biogeography, addressing questions best answered by a large dataset of subjects and body sites that are deeply sampled by sequencing.
Abstract: Background
Characterizing the biogeography of the microbiome of healthy humans is essential for understanding microbial associated diseases. Previous studies mainly focused on a single body habitat from a limited set of subjects. Here, we analyzed one of the largest microbiome datasets to date and generated a biogeographical map that annotates the biodiversity, spatial relationships, and temporal stability of 22 habitats from 279 healthy humans.
