... biosynthesis. Imaging mass spectrometry visualized lactate-rich tissues, such as the dorsal or posterior neural tube, somites and head mesenchyme. Furthermore, we found that the heterochronic gene Lin28a could act as a regulator of the metabolic changes observed during CB. Perturbation of glucose metabolism...

... protein with two homologs in mice: Lin28a and Lin28b. Here we show that Lin28a/b are enriched in early NPCs and their expression declines during neural differentiation. Lin28a single-knockout mice show reduced NPC proliferation, enhanced cell cycle exit and a smaller brain, whereas mice lacking both...

.... The Xenopus genome contains two Lin28-related genes, lin28a and lin28b. lin28a is expressed zygotically, whereas lin28b is expressed both zygotically and maternally. Both lin28a and lin28b are expressed in pluripotent cells of the Xenopus embryo and are enriched in cells that respond to mesoderm-inducing...
