RESEARCH ARTICLES
Microenvironmental stimuli induce different macrophage polarizations in experimental models of emphysema
Summary: The CS-induced model showed M1 and M2-related genes and chemokines, whereas the PPE-induced model showed a downregulation of M2- and an increase in M1-related genes and chemokines.
Soft substrate maintains proliferative and adipogenic differentiation potential of human mesenchymal stem cells on long-term expansion by delaying senescence
Summary: hMSCs retain their stemness by delaying senescence when expanded in vitro on soft polyacrilamide gel.
Quantitative analysis of the ThrbCRM1-centered gene regulatory network
Summary: Systematic variation of the levels of a transcriptional reporter plasmid, its trans-acting factors and transcription factor binding sites reveals properties of a retinal enhancer during development.
TXNIP mediates high glucose-induced mitophagic flux and lysosome enlargement in human retinal pigment epithelial cells
Summary: Mitophagy is critical for removing damaged mitochondria and maintaining cellular health. Here, the influence of high glucose and TXNIP on mitophagy-lysosome axis dysregulation in human retinal pigment epithelium is revealed.
penner/lgl2 is required for the integrity of the photoreceptor layer in the zebrafish retina
Summary: Knockdown of penner/lgl2 leads to a breakdown of the outer plexiform layer and the outer limiting membrane in the zebrafish retina due to impaired cell adhesion.
Actin cytoskeleton remodeling defines a distinct cellular function for adhesion G protein-coupled receptors ADGRL/latrophilins 1, 2 and 3
Summary: Synapses involve the adhesion function of latrophilins within existing neuronal extensions. We show that latrophilins engage the actin cytoskeleton, both constitutively and upon ligand stimulation, to dictate cell extension patterns.
Characterization and comparative analyses of transcriptomes of cloned and in vivo fertilized porcine pre-implantation embryos
Summary: Comparative transcriptome analyses of cloned and in vivo fertilized pre-implantation embryos: transcriptional defects and reprogramming barriers in porcine somatic cell nuclear reprogramming.
The chromodomain helicase CHD4 regulates ERBB2 signaling pathway and autophagy in ERBB2+ breast cancer cells
Summary: Inhibition of CHD4 expression impairs cell proliferation and survival through downregulation of ERBB2 signaling and block of autophagy. Therefore, CHD4 should be considered a potential target in ERBB2+ breast cancers.
Transcriptomic analysis of Spodoptera frugiperda Sf9 cells resistant to Bacillus thuringiensis Cry1Ca toxin reveals that extracellular Ca2+, Mg2+ and production of cAMP are involved in toxicity
Summary: Insect cell lines sensitive and resistant to entomopathogenic toxins were developed. Comparative transcriptomic analysis performed on these cell lines provides new information about mechanisms of toxins toxicity.
Higher incubation temperatures produce long-lasting upward shifts in cold tolerance, but not heat tolerance, of hatchling geckos
Summary: Hatchling geckos from current temperature incubation tolerated cold better than hatchlings from future temperature incubation. The developmental shift in cold tolerance persisted for 6 months, and could therefore influence hatchling survival.
Prostaglandin E2 promotes embryonic vascular development and maturation in zebrafish
Summary: Overproduction of PGE2 causes inflammation and cancer and its blockage results in serious physiological consequences. This study investigated the novel roles of PGE2 in early vascular development of zebrafish.
Nematicidal actions of the marigold exudate α-terthienyl: oxidative stress-inducing compound penetrates nematode hypodermis
Summary: α-terthienyl, an exudate of the marigold, effectively penetrates the nematode hypodermis in Caenorhabditis elegans dauer and Meloidogyne incognita J2 larvae, and exerts nematicidal activity through oxidative stress induction.
Dominant-negative inhibition of canonical Notch signaling in trophoblast cells does not disrupt placenta formation
Summary: Using transgenic mice with a dominant-negative form of Mastermind-like1 and Cyp19-Cre and Tpbpa-Cre drivers, we found that dominant negative inhibition of canonical Notch signaling in trophoblast cells does not disrupt placenta formation.
Motion characteristics of human roller skating
Summary: The motion characteristics of human roller skating are studied using the theory of mechanism design. The skating inverted pendulum is used to describe roller skating with one supporting leg.
Distinct gene-selective roles for a network of core promoter factors in Drosophila neural stem cell identity
Summary: A subset of TAFs has been identified as regulators of NSC identity in Drosophila, which could inform human neurological disorders linked to TAF variants.
Effect of intracerebroventricular epinephrine microinjection on blood pressure and urinary sodium handling in gestational protein-restricted male adult rat offspring
Summary: We evaluated the effect of intracerebroventricular microinjections of adrenergic agonists at increasing concentrations, and μ1 and μ2-adrenergic receptors antagonists on blood pressure and urinary sodium in hypertensive low- and normal-protein rat offdpring.
METHODS & TECHNIQUES
Simultaneous expression of ClopHensor and SLC26A3 reveals the nature of endogenous oxalate transport in CHO cells
Summary: We expressed the fluorescent fusion protein, ClopHensor, for the first time in a multi-well format to assess for bicarbonate and chloride exchange by an endogenous oxalate transporter in CHO cells.

Daniel Gorelick on Open Access and Read & Publish in Biology Open
Editor-in-Chief, Daniel Gorelick, talks about Biology Open, the importance of Open Access publishing and how The Company of Biologists’ Read & Publish initiative benefits researchers.
A new model for cephalopod neurobiology
Fabián Vergara-Ovalle and colleagues show the distribution of the nitric oxide system within the nervous system, particularly in areas associated with olfactory and visual information processing, in Octopus maya. Since these octopi can be cultured in the lab, they represent a valuable model for studying cephalopod neurobiology.
How we support early-career researchers
Biology Open, its sister journals and its not-for-profit publisher, The Company of Biologists, support early-career researchers in numerous ways, helping them grow their network and raise their profile. Find out what we can do to support you.
