FEBS Open Bio, EarlyView.Glioblastoma cells express calcitonin receptor variants (CT receptor isoforms) that may help them survive stress. Using qPCR, transcript‐specific long‐read nanopore sequencing, immunofluorescence co‐localisation and comparative sequence analysis, this study identifies a novel alternatively spliced CALCR transcript that encodes the CTb receptor isoform ...

Metchnikoff’s scientific ideas and modernity
Annals of Mechnikov's Institute, 2020 On May 15, 2015, we celebrated the 170th anniversary of the Ilya Metchnikoff, the author of the hypothesis about parenchymella, the father of cellular immunology and inflammation theory, founder of gerontology, aging and longevity science.

Advanced Science, EarlyView.The sea cucumber Holothuria leucospilota detects blue and adjacent wavelengths of light via an r‐opsin with a maximum absorption at 459 nm. In the oral tentacles, papillae, and tube feet, distinct light‐sensing structures with specialized morphologies are formed, constituting a unique pentaradial and bilateral combined photoreception system.

Embryonic development of the Mediterranean starfish Hacelia attenuata
Developmental Dynamics, EarlyView.Abstract Background Starfish play essential ecological roles as predators and ecosystem regulators; however, detailed developmental descriptions exist for only a handful of species, none of which are from the Mediterranean Sea. Results In this study, we provide the first full account of the development of the Mediterranean starfish Hacelia attenuata ...

The Development of Transplanted Fragments of Fundulus Gastrulae [PDF]
Proceedings of the National Academy of Sciences, 1953 It was reported by Lutherl some time ago that for the egg of Salmo both embryonic and extra-em'ryonic sectors of the blastoderm accomplished considerable differentiation after transplantation at early gastrula stages to the yolk-sac epithelium of older trout fry.

Zebrafish ventral gastrula fate map reveals neural crest progenitor domain
Developmental Dynamics, EarlyView.Abstract Background Fate maps relate progenitor cell positions to later fates and locations of their progeny, revealing early embryonic organization. Previous zebrafish fate maps identified the origin of germ layers and derivative cell fates, but ventral gastrula progenitor domains were not fully resolved. In particular, the neural crest, a multipotent
