New work from UC Davis and the University of Utah shows how the 3D structure of DNA inside a germ cell commits it to develop into a sperm cell. The discovery could improve understanding of fertility ...

About 9% of men of reproductive age in the United States experience fertility problems. One of the many causes of male ...

Two new studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature Structural ...

Early in the development of sperm, a strange event happens: the X and Y chromosomes condense into tight packages and are sequestered away from the other 44 human chromosomes. If any part of this ...

Two new landmark studies show how a seeming tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published March 3 as two papers in ...

Gene expression related to fertilization, sperm motility, and sperm structure in the testes of Tle6 -deficient mice showed an overall increase. Together, the findings of this study highlighted the ...

Researchers led by Meng Wenxiang from the Institute of Genetics and Developmental Biology of the Chinese Academy of Sciences have shown that knocking out of the calmodulin-regulated ...

A colony of human embryonic stem cells is seen on a computer monitor at the University of Wisconsin–MadisonDarren Hauck / Getty Researchers at Newcastle University in England report they have coaxed ...

Researchers showed how what appears to be a tangle of DNA is actually organized into a structure that coordinates thousands of genes to form a sperm cell. The work, published as two papers in Nature ...

Researchers at the UC Davis College of Biological Sciences have discovered that a little-known protein called ATF7IP2 helps to inactivate the X and Y chromosomes during cell divisions that lead to ...
