Red-eared slider turtles are genetically bipotential for sex determination. In this species, as in many other reptiles, incubation temperature of the egg determines gonadal sex. At higher incubation temperatures females are produced and increasing temperature appears to increase estrogen production in the embryonic brain. Treatment of eggs incubating at a male-producing temperature with exogeno...

OBJECTIVE Sonic hedgehog is produced in gastric epithelial cells and plays a crucial role in parietal cell function and the regulation of gastric epithelial cell differentiation. Emerging evidence suggests that the sonic hedgehog pathway is not only involved in the development of cancers but also in their progression and aggressiveness. METHODS To assess its prognostic value in gastric cancer...
