Researchers report the function of reverse-twisting DNA

Normally, the two strands of the DNA double helix wind around each other in a right-handed spiral. However, there is another conformation called Z-DNA in which the strands twist to the left. The function of Z-DNA has remained ...

Using artificial RNA editing to restore genetic code

Various genetic diseases caused by point mutations have no established therapeutic approaches. Prof. Tsukahara and colleagues (Japan Advanced Institute of Science and Technology) are studying a therapeutic method using artificial ...

Two genes linked to why telomeres stretch in cancer cells

Scientists at Johns Hopkins have provided more clues to one of the least understood phenomena in some cancers: why the "ends caps" of cellular DNA, called telomeres, lengthen instead of shorten.

Scientists identify genes tied to increased risk of ovarian cancer

A team of researchers at UCLA's Jonsson Comprehensive Cancer, Cedars-Sinai Cancer and Dana-Farber Cancer Institute have newly identified 34 genes that are associated with an increased risk for developing the earliest stages ...
