The matricellular protein Fibulin-5 regulates β-cell proliferation in an autocrine/paracrine manner

open access: yesiScience
Summary: The matricellular protein Fibulin-5 (Fbln5) is a secreted protein that is essential for elastic fiber formation, and pancreatic islets are usually surrounded by the extracellular matrix (ECM), which includes elastic fibers.

Uncoupling protein 2 and aldolase B impact insulin release by modulating mitochondrial function and Ca2+ release from the ER

open access: yesiScience, 2022
Summary: Uncoupling protein 2 (UCP2), a mitochondrial protein, is known to be upregulated in pancreatic islets of patients with type 2 diabetes (T2DM); however, the pathological significance of this increase in UCP2 expression is unclear.

Evolving more efficient digital circuits by allowing circuit layout evolution and multi-objective fitness [PDF]

open access: yes, 1999
We use evolutionary search to design combinational logic circuits. The technique is based on evolving the functionality and connectivity of a rectangular array of logic cells whose dimension is defined by the circuit layout.

Bridging the gap between omics and earth system science to better understand how environmental change impacts marine microbes [PDF]

open access: yes, 2015
The advent of genomic-, transcriptomic- and proteomic-based approaches has revolutionized our ability to describe marine microbial communities, including biogeography, metabolic potential and diversity, mechanisms of adaptation, and phylogeny and ...

Complementary approaches to understanding the plant circadian clock [PDF]

open access: yes, 2010
Circadian clocks are oscillatory genetic networks that help organisms adapt to the 24-hour day/night cycle. The clock of the green alga Ostreococcus tauri is the simplest plant clock discovered so far.

FXR in bone metabolism: An emerging regulator

open access: yesiScience
Summary: Farnesoid X receptor (FXR), a core regulator of bile acid metabolism, is also a key modulator of bone metabolism that influences bone remodeling by regulating osteoblast and osteoclast activities.

Essential versus accessory aspects of cell death: recommendations of the NCCD 2015 [PDF]

open access: yes, 2014
Cells exposed to extreme physicochemical or mechanical stimuli die in an uncontrollable manner, as a result of their immediate structural breakdown. Such an unavoidable variant of cellular demise is generally referred to as ‘accidental cell death’ (ACD).

Molecular and cellular mechanisms underlying the evolution of form and function in the amniote jaw. [PDF]

open access: yes, 2019
The amniote jaw complex is a remarkable amalgamation of derivatives from distinct embryonic cell lineages. During development, the cells in these lineages experience concerted movements, migrations, and signaling interactions that take them from their ...

P-cadherin-dependent adhesions are required for single lumen formation and HGF-mediated cell protrusions during epithelial morphogenesis

open access: yesiScience
Summary: During epithelial morphogenesis, in vivo, epithelial cells form cysts enclosing a single, hollow lumen and extend protrusions as a precursor for tubulogenesis.

RNA interference in marine and freshwater sponges [PDF]

open access: yes, 2011
Background: The marine sponge Tethya wilhelma and the freshwater sponge Ephydatia muelleri are emerging model organisms to study evolution, gene regulation, development, and physiology in non-bilaterian animal systems. Thus far, functional methods (i.e.,
