Despite the importance of the retinal pigment epithelium (RPE) for vision, the molecular processes involved in its specification are poorly understood. We identified two new mutant alleles for the zebrafish gene chokh (chk), which display a reduction or absence of the RPE. Unexpectedly, the neural retina (NR) in chk is specified and laminated, indicating(More)
Heart failure is characterized by a debilitating decline in cardiac function, and recent clinical trial results indicate that improving the contractility of heart muscle cells by boosting intracellular calcium handling might be an effective therapy. MicroRNAs (miRNAs) are dysregulated in heart failure but whether they control contractility or constitute(More)
All cells have electric potentials across their membranes, but is there really compelling evidence to think that such potentials are used as instructional cues in developmental biology? Numerous reports indicate that, in fact, steady, weak bioelectric fields are observed throughout biology and function during diverse biological processes, including(More)
Epimorphic regeneration is a unique and complex instance of postembryonic growth observed in certain metazoans that is usually triggered by severe injury [Akimenko et al., 2003; Alvarado and Tsonis, 2006; Brockes, 1997; Endo et al., 2004]. Cell division and migration are two fundamental biological processes required for supplying replacement cells during(More)
