EPSA1 and VPF genes expression during embryonic and larval development period of Beluga, Huso huso

Background: The Endothelial PAS domain-containing protein 1 (EPSA1) is the key transcriptional regulator of hypoxic response and Vascular Permeability Factor (VPF) is an important growth factor for vascular development and angiogenesis. OBJECTIVES: In the present study, the levels of the EPSA1 coding gene and VPF transcripts were evaluated during Larval development of Beluga, Huso huso. METHODS...

Lens Induction in the Salamander (Amblystoma punctatum) with Special Reference to Conditions in Experimentally Produced Cyclopia *

It has long been known that the early optic vesicle and cup are much concerned with the growth and differentiation of the lens in the vertebrate eye. Le Cron"2 first demonstrated this fact when he isolated the lens-forming cells in Amblystoma embryos at various early stages in development by merely removing the underlying optic anlage. His experiments showed that the longer the lens epithelium ...

Effects of Salinity on Embryonic and Early Larval Development of a Tropical Sea Urchin, Salmacis sphaeroides

Effects of salinity on fertilization, embryonic stage, and early larval development and growth performances of short-spined white sea urchin, Salmacis sphaeroides were conducted under a controlled laboratory condition. The experiment was carried out with seven salinity treatments (15, 20, 25, 30, 35, 40 and 45 PSU), each of which was triplicated. Significantly highest fertilization success was ...
