Limb regeneration in brittle stars

A new study published in Frontiers in Zoology examined the developmental process involved in regulating limb regeneration in brittle stars (Amphiura filiformis) following amputation of an arm. Limb regeneration is a multi-stage process involving initial healing and repair of the wounded site, initial growth of the limb followed by development of more complex layers of cells until…

Exercise grows bigger fish

A new study published in the American Journal of Physiology – Regulatory, Integrative and Comparative Physiology explored the effects of exercise on growth and hormone regulation in gilthead sea bream (Sparus aurata). The main hormones that regulate growth are, perhaps not surprisingly, growth hormone and insulin-like growth factor. Researchers discovered young gilthead seam bream that underwent…

New research published in PLOS Genetics shows that starving C. elegans (Caenorhabditis elegans) during the late larval stage of development when the worms are undergoing tissue growth and formation halts cellular activity at previously unknown checkpoints in their development. These findings show that nutrition is an important cue to signal whether or not the worms should…

How zebrafish sense calcium

Calcium is very important for the normal development, growth and survival of most vertebrates. Therefore, regulation of calcium intake and disposal is well-controlled. Mammals obtain most of their calcium from the diet, whereas fish obtain calcium by absorbing it from the external environment. For adults, this occurs in the gills and for larvae it is…
