Cell pathway, disease linked to histone action

...in was identified that modifies H2A, which in turn regulates normal cell pathways and cell growth. When the function of this protein was blocked in tadpole embryos, the front-to-back body patterning that happens as they mature was altered, said Hengbin Wang, Ph.D., an assistant professor in the UAB Depart...

Biologists rediscover endangered frog population

...oo's Institute for Conservation Research was the first to breed a mountain yellow-legged frog in captivity. That amphibian has recently morphed from a tadpole into a froglet, or juvenile frog. "Historically, scientists have had great difficulty breeding frogs in captivity," said Jeff Lemm, an animal resear...

Carnegie's Donald Brown receives lifetime achievement award from Society for Developmental Biology

...lex problem, the control of gene expression that regulates the transformation of tadpoles into frogs. The many developmental changes that occur when a tadpole turns into a frog are controlled entirely by thyroid hormone. By studying its role in amphibian metamorphosis, Brown and colleagues developed a strate...

Climate change effects on imperiled Sierra frog examined

...water equivalent gone by 2090. Sierra Nevada Yellow-legged frogs need two to four years of permanent water to complete their development so repeated tadpole mortality from lakes drying up in summer leads to population decline. The scientists found the effect to be a distinct mortality mechanism that could ...

Researchers find signal that switches on eye development -- could lead to 'eye in a dish'

...ase2) had a dramatic affect on eye development in the tadpoles grown from these embryos. When introduced in cells that would form the head area of the tadpole multiple eyes appeared to be created. That was not the only surprise. When it was introduced in some cells that formed body parts outside the head are...

Nutrient pollution drives frog deformities by ramping up infections, says CU-Boulder study

...te in frogs rose by two- to five-times in those tanks, Johnson said. As few as 12 trematode larvae, known as cercariae, can kill or deform a single tadpole by burrowing into their limb regions and disrupting normal leg development, he said. A single infected snail can produce more than 1,000 cercariae in...

Time of day tempers tadpoles' response to predators

... To a tiny tadpole, life boils down to two basic missions: eat, and avoid being eaten. But there's a trade-off. The more a tadpole eats, the faster it grows big enough to transform into a frog; yet finding food requires being active, which ups the odds of becoming someone else's d...

Picky female frogs drive evolution of new species in less than 8,000 years

...apparently had diverged enough during their million-year separation that offspring of southern females and northern males failed to develop beyond the tadpole stage. Though crosses involving northern females and southern males successfully produced frogs, the offspring developed more slowly than the offsprin...
