Alexei Poliakov et al.
The Journal of cell biology, 183(5), 933-947 (2008-12-03)
In this study, we investigated whether the ability of Eph receptor signaling to mediate cell repulsion is antagonized by fibroblast growth factor receptor (FGFR) activation that can promote cell invasion. We find that activation of FGFR1 in EphB2-expressing cells prevents...

Cell death and differentiation, 26(8), 1453-1466 (2018-10-27)
Transmembrane protein 268 (TMEM268) encodes a novel human protein of previously unknown function. This study analyzed the biological activities and molecular mechanisms of TMEM268 in vivo and in vitro. We found that TMEM268 deletion decreases cell viability, proliferation, and cell...

Cryobiology, 85, 63-72 (2018-10-08)
Cryopreservation of endothelium is one of the major challenges in the cryopreservation of complex tissues. Human umbilical vein endothelial cells (HUVECs) in suspension are available commercially and recently their post-thaw cell membrane integrity was significantly improved by cryopreservation in 5%...

Citrullination, the deimination of peptidylarginine residues into peptidylcitrulline, has been implicated in the etiology of several diseases. In multiple sclerosis, citrullination is thought to be a major driver of pathology through hypercitrullination and destabilization of myelin. As such, inhibition of...

Journal of cell science, 132(4) (2018-09-29)
EB proteins track the ends of growing microtubules and regulate microtubule dynamics both directly and by acting as the hub of the tip-tracking network. Mammalian cells express cell type-specific combinations of three EB proteins with different cellular roles. Here, we...

The EMBO journal, 28(12), 1684-1696 (2009-05-09)
Agonist-induced ubiquitination of the beta(2) adrenergic receptor (beta(2)AR) functions as an important post-translational modification to sort internalized receptors to the lysosomes for degradation. We now show that this ubiquitination is reversed by two deubiquitinating enzymes, ubiquitin-specific proteases (USPs) 20 and...
Jason Fan et al.
Molecular metabolism, 34, 97-111 (2020-03-18)
Diabetes is characterized by pancreatic β-cell dedifferentiation. Dedifferentiating β cells inappropriately metabolize lipids over carbohydrates and exhibit impaired mitochondrial oxidative phosphorylation. However, the mechanism linking the β-cell's response to an adverse metabolic environment with impaired mitochondrial function remains unclear. Here...

EMBO reports, 21(10), e50718-e50718 (2020-08-14)
Senescent cells display senescence-associated (SA) phenotypic programs such as stable proliferation arrest (SAPA) and a secretory phenotype (SASP). Senescence-inducing persistent DNA double-strand breaks (pDSBs) cause an immediate DNA damage response (DDR) and SAPA, but the SASP requires days to develop....

Decorin is a member of small leucine-rich proteoglycan family, which is involved in multiple biological functions mainly as a structural and signaling molecule, and disturbances in its own metabolism plays a crucial role in the pathogenesis of osteoarthropathy. In this...
Shiny Shengzhen Guo et al.
Development (Cambridge, England), 147(22) (2020-10-15)
The notochord drives longitudinal growth of the body axis by convergent extension, a highly conserved developmental process that depends on non-canonical Wnt/planar cell polarity (PCP) signaling. However, the role of cell-matrix interactions mediated by integrins in the development of the...

Leda Lacaria et al.
Biochemical and biophysical research communications, 525(4), 836-840 (2020-03-14)
Living cells interact with the extracellular matrix (ECM) transducing biochemical signals into mechanical cues and vice versa. Thanks to this mechano-transduction process, cells modify their internal organization and upregulate their physiological functions differently. In this complex mechanism integrins play a...

Integrative biology : quantitative biosciences from nano to macro, 9(2), 123-134 (2017-01-20)
Microenvironmental cues comprising surface-mediated and soluble factors control cellular signaling mechanisms underlying normal cellular responses that define homeostatic and diseased cell states. In order to measure cell signaling in single adherent cells, we developed a novel microsphere-based flow cytometry approach....

Broad applications of electropolymerized conducting polymers (CPs) often prefer thinner soft electrodes to comply with downscaling of the fabrication resolution. However, high conductivity of existing CP films vanishes as thickness decreases to the nanoscale (i.e., below 100 nm), with an...

Nature materials, 20(3), 410-420 (2020-10-21)
Contractile actomyosin networks are responsible for the production of intracellular forces. There is increasing evidence that bundles of actin filaments form interconnected and interconvertible structures with the rest of the network. In this study, we explored the mechanical impact of...

Aneuploidy, an abnormal chromosome number, has been linked to aging and age-associated diseases, but the underlying molecular mechanisms remain unknown. Here we show, through direct live-cell imaging of young, middle-aged, and old-aged primary human dermal fibroblasts, that aneuploidy increases with...

Smad4 mutant embryos arrest shortly after implantation and display a characteristic shortened proximodistal axis, a significantly reduced epiblast, as well as a thickened visceral endoderm layer. Conditional rescue experiments demonstrate that bypassing the primary requirement for Smad4 in the extra-embryonic...

Conferring antithrombogenicity to tissue-engineered vascular grafts remains a major challenge, especially for urgent bypass grafting that excludes approaches based on expanding autologous endothelial cells (ECs) that requires weeks of cell culture. Adipose-derived stem cells (ASCs) are available from most patients...
