BACKGROUND: Epithelial tissues of the gastrointestinal tract and the liver express predominantly cytokeratin 8 and cytokeratin 18. In vitro experiments and animal studies have demonstrated a ...

Deep in the Pacific, humans have tracked a mysterious whale’s call for decades—but no other whale seems to respond. And now, we might be running out of time to find the source.

OutSee’s discovery team, from left, are James Peach, chief operating officer, Chang Lu, chief scientific officer and ...

The Religious ‘Nones’ are now the largest religious cohort in the U.S. (28%). They are more prevalent among American adults ...

Study finds surprising way that genetic mutation causes Huntington's disease, transforming understanding of the disorder Researchers studying brain cells from Huntington's patients show that the ...

Researchers in the group of Dr. Myriam Charpentier discovered a mutation in a gene in the legume Medicago truncatula that reprograms the signaling capacity of the plant so that it enhances ...

For 30 years, researchers have known that Huntington's is caused by an inherited mutation in the Huntingtin (HTT) gene, but they didn't know how the mutation causes brain cell death. A study ...

A mutation that causes an amino-acid substitution in a channel called CNGC15 in the plant cell’s nucleus boosts the formation of such endosymbiotic relationships. Studying ion channels in their ...

Their findings, published in Nature Aging, describe a never-before-seen link between the two most accepted explanations: random genetic mutations and predictable epigenetic modifications.

This means that the damage has multiple chances to generate harmful mutations, which can lead to cancer. While most known types of DNA damage are fixed by our cells' in-house DNA repair mechanisms ...
