The process enables some viruses to insert their genetic material into the DNA of healthy human cells, which can lead to tumors and other diseases.

Healthy human cells typically turn on nearly half of their 20,000 genes at any given time, and they choose those genes carefully to produce the desired cellular responses.

They then mimicked the effects of such mutations in lab dishes by systematically inactivating each of these cancer - associated genes in healthy human cells, creating 625 different perturbations that mirrored distinct genetic mutations seen in real breast and ovarian cancers.

And when he checked, Avivi found that the fibroblasts and their secretions didn't harm healthy human cells.

To determine whether the Zika virus caused this, a number of independent teams of researchers — including two in Brazil and one at the University of California, San Diego — created brain organoids from healthy human cells and infected some of them with the Zika virus.

James Christiansen, professor of biology at Drake University in DesMoines, is studying how telomeres, the simple, non-genetic DNAsequences that sheathe the ends of chromosomes, function in reptiles.Each time a healthy human cell divides, it loses a little bit of thetelomere, until the strands are too short to protect the chromosomes.At that point the DNA in a cell begins to break down, which triggerssenescence and death.

The 6 - HAP doesn't seem to be damaging to healthy human cells.
