Regeneration in bipinnaria larvae of the bat star Patiria miniata induces rapid and broad new gene expression
BACKGROUND Some metazoa have the capacity to regenerate lost body parts. This phenomenon in adults has been classically described in echinoderms, especially in sea stars (Asteroidea). Sea star bipinnaria larvae can also rapidly and effectively regenerate a complete larva after surgical bisection. Understanding the capacity to reverse cell fates in the larva is important from both a developmenta...
متن کاملNme Gene Family Evolutionary History Reveals Pre-Metazoan Origins and High Conservation between Humans and the Sea Anemone, Nematostella vectensis
BACKGROUND The Nme gene family is involved in multiple physiological and pathological processes such as cellular differentiation, development, metastatic dissemination, and cilia functions. Despite the known importance of Nme genes and their use as clinical markers of tumor aggressiveness, the associated cellular mechanisms remain poorly understood. Over the last 20 years, several non-vertebrat...
متن کاملThe effect of monsoon on fish larva assemblage changes in Gowatr Bay, North Oman Sea
The study and research of abundance and diversity variation of fish larva (Ichthyoplankton stages) was done in Gowatr Bay during autumn 2006 - summer 2007. Five stations were selected for sampling, and Bongo-Net with 300µ mesh size was towing from bottom to surface. During of survey, totally 531 larvae belong to 11 families were collected and identified. The mean abundance estimated 12.17 larva...
متن کاملPreliminary studies on the impact of fish cage culture rainbow trout (Oncorhynchus mykiss) on zooplankton structure in the southwestern Caspian Sea
The ecosystem of the Caspian Sea have been strikingly changed by human activities. This area has undergone significant ecological alterations and serious environmental degradation since the beginning of 1990s. The impact of fish cage culture on the zooplankton community was studied in the southwestern Caspian Sea, off Jafrud during January to April 2013. A total of 12 zooplankton belonging to 9...
متن کاملMechanisms of tentacle morphogenesis in the sea anemone Nematostella vectensis.
Evolution of the capacity to form secondary outgrowths from the principal embryonic axes was a crucial innovation that potentiated the diversification of animal body plans. Precisely how such outgrowths develop in early-branching metazoan species remains poorly understood. Here we demonstrate that three fundamental processes contribute to embryonic tentacle development in the cnidarian Nematost...
