Documenting den characteristics of bears and wolves in the Greater Yellowstone Ecosystem using LIDAR technology

Wildlife Society Bulletin, EarlyView.
Previous studies have documented den site characteristics through physical measurements recorded by researchers in the field. Using the light detection and ranging (LiDAR) sensor onboard an Apple iPad Pro, we scanned the interior of black and grizzly bear dens (n = 9) located in the Greater Yellowstone Ecosystem (GYE) to generate point clouds of den ...

Comprehensive Analysis of the Expression and Prognosis for in Breast Carcinoma

Cell Transplantation, 2020
Secreted frizzled-related proteins ( SFRPs ) are a group of five secreted glycoproteins— SFRP1 , SFRP2 , SFRP3 (frizzled related protein , FRZB ), SFRP4 , and SFRP5 —which contain a frizzled-related cysteine-rich domain and a netrin module.

Structure and functional motifs of GCR1, the only plant protein with a GPCR fold? [PDF]

, 2013
Whether GPCRs exist in plants is a fundamental biological question. Interest in deorphanizing new G protein coupled receptors (GPCRs), arises because of their importance in signaling.

BubR1 Insufficiency Drives Transcriptomic Alterations and Pathology Associated With Cardiac Aging and Heart Failure

Aging Cell, EarlyView.
Transcriptomic and cellular analyses of BubR1 hypomorphic hearts reveal disruptions in key pathways and upregulation of markers linked to impaired cardiac structure and function. Comparative transcriptomic analysis shows that BubR1 insufficiency mirrors changes seen in aged and failing hearts. A key finding of this study is that BubR1 levels decline in

BRAIDing receptors for cell-specific targeting

eLife
Systemic toxicity is a major challenge in the development of therapeutics. Consequently, cell-type-specific targeting is needed to improve on-target efficacy while reducing off-target toxicity.

Alternative Polyadenylation Contributes to Fibroblast Senescence in Pulmonary Fibrosis

Aging Cell, EarlyView.
In aging or fibrotic fibroblasts, NUDT21 is downregulated, leading to alternative polyadenylation/3′ UTR shortening of STAT3 pathway genes, enhancing their protein expression and promoting STAT3 phosphorylation. Activated STAT3 signaling subsequently drives the expression and release of senescence‐associated secretory phenotype (SASP) factors, thereby ...

Forced expression of Wnt antagonists sFRP1 and WIF1 sensitizes chronic myeloid leukemia cells to tyrosine kinase inhibitors

Tumor Biology, 2017
Chronic myeloid leukemia is a clonal myeloproliferative disorder that arises from the neoplastic transformation of the hematopoietic stem cell, in which the Wnt/β-catenin signaling pathway has been demonstrated to play an important role in disease ...

A potential role for Dkk-1 in the pathogenesis of osteosarcoma predicts novel diagnostic and treatment strategies. [PDF]

, 2007
Canonical Wnt signaling is an osteo-inductive signal that promotes bone repair through acceleration of osteogenic differentiation by progenitors. Dkk-1 is a secreted inhibitor of canonical Wnt signaling and thus inhibits osteogenesis.

Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.
