Constitutive activation of notch signaling results in excessive cellular proliferation and a wide range of malignan-cies.

متن کاملDNA sampling from eggshells and microsatellite genotyping in rare tropical birds: Case study on Brazilian Merganser
This study shows that sampling maternal DNA from hatched and abandoned eggshells is a viable noninvasive strategy for studying the genetics of rare or endangered tropical birds, as exemplified here by the Brazilian Merganser (Mergus octosetaceus). Eighteen microsatellites were isolated from enriched libraries and nine heterologous loci from related species were tested. Seven loci were amplified...
