推荐 为解决两栖动物表观遗传衰老研究工具匮乏问题，研究人员构建非洲爪蟾（Xenopus tropicalis）DNA 甲基化时钟。基于 192 只爪蟾皮肤样本的靶向亚硫酸氢盐测序，发现衰老相关 CpG 位点富集于异染色质等区域，且机制与哺乳动物保守。该工具为衰老生物学及跨 ...

We provide a simple, quantitative explanation for the capacity of the Xenopus embryo to scale pattern with size. Three key features of the BMP patterning network underlie this capacity.

A novel method for monitoring caspase activity in living Xenopus oocytes and early embryos is described here. The approach, using microinjection of a near-infrared caspase substrate that emits ...

Two genomes are better than one? African clawed frogs of the genus Xenopus (zen'-uh-pus, literally "strange foot") comprise more than 20 species native to sub-Saharan Africa. In the early 20th ...

They are named for the African clawed frog Xenopus laevis, which supplies all their cells, and the suggestion, encapsulated in the prefix, that something strange, alien, is at work. A xenobot ...

Xenopus, meaning "strange foot," is a genus of more than 20 frog species native to sub-Saharan Africa. When biologists discovered in the early 20th century that these frogs were unusually ...

The "Hogben test" got its start in 1930, when British biologist Lancelot Hogben began looking into what he called a godsend for hormone research: The African clawed frog, or Xenopus laevis.

The African clawed frog, Xenopus laevis, is a palm-sized, greenish-gray animal that hails from the ponds and rivers of sub-Saharan Africa, where it lived for millions of years without anyone ...

I am interested in how these networks form. I am especially interested in the molecular pathways underlying this process. My lab studies these questions in the developing visual system of the Xenopus ...

The Common Platanna (Xenopus laevis), is also known as the African Clawed Frog. PHOTO: Nick Evans THE Common Platanna (Xenopus laevis), also known as the African Clawed Frog, has got to be one of ...

Amphibian chytrid fungus seems to have spread around the world astride the South African clawed frog, Xenopus laevis, which was exported for use as a pregnancy test. Wait a second—how do you use ...

In 1938, Dr. Edward R. Elkan wrote in the British Medical Journal: The discovery of what is now known as the xenopus pregnancy test is based on experiments conducted by Hogben (1930, 1931), who ...
