Vitamin K prevents cell death: A new function for a long-known molecule
Phys.org ^ | 8/3/2022 | Helmholtz Association of German Research Centres

Posted on 08/03/2022 9:24:20 PM PDT by LibWhacker

A team of researchers located at Helmholtz Munich reports on a novel function of vitamin K, which is generally known for its importance in blood clotting. The researchers discovered that the fully reduced form of vitamin K acts as an antioxidant efficiently inhibiting ferroptotic cell death. Ferroptosis is a natural form of cell death in which cellular iron plays an important role and which is characterized by the oxidative destruction of cellular membranes. In addition, the team identified FSP1 as the warfarin-insensitive enzyme reducing vitamin K, the identity of which had been postulated but remained unknown for more than half a century.

During the last years, ferroptosis has been implicated as a driver of Alzheimer's disease and acute organ injuries among many other diseases. Thus, the present findings put forward the concept that vitamin K treatment might be a new powerful strategy to ameliorate these ferroptosis-related diseases.

Vitamin K is a potent ferroptosis suppressor

Since ferroptosis prevention is considered a highly promising approach for the therapy of many degenerative diseases, new mechanisms and compounds regulating ferroptosis are extensively being explored. To identify these new molecules, a team of researchers led by Dr. Eikan Mishima and Dr. Marcus Conrad, both from the Institute of Metabolism and Cell Death at Helmholtz Munich, along with collaborators from Tohoku University (Japan), University of Ottawa (Canada) and Technical University of Dresden (Germany), systematically studied a number of naturally occurring vitamins, as well as their derivatives. "Surprisingly, we identified that vitamin K, including phylloquinone (vitamin K1) and menaquinone-4 (vitamin K2), is able to efficiently rescue cells and tissues from undergoing ferroptosis," Dr. Eikan Mishima, first author of the study explained.

Unraveling the long sought-after vitamin K reducing enzyme FSP1

In 2019 a team of researchers around Dr. Marcus Conrad already identified an enzyme as a novel and strong inhibitor of ferroptosis: ferroptosis suppressor protein-1, short FSP1. The research team now found that the fully reduced form of vitamin K (i.e., vitamin K hydroquinone) acts as a strong lipophilic antioxidant and prevents ferroptosis by trapping oxygen radicals in lipid bilayers. In addition, they identified that FSP1 is the enzyme that efficiently reduces vitamin K to vitamin K hydroquinone, thereby driving a novel non-canonical vitamin K cycle. Since vitamin K is critically involved in blood clotting processes, the team further showed that FSP1 is responsible for the vitamin K-reduction pathway insensitive against warfarin, one of the most commonly prescribed anticoagulants.

Breakthrough in understanding vitamin K metabolism

Unraveling the identity of this enzyme solved the last riddle of vitamin K metabolism in blood clotting and elucidated the molecular mechanism of why vitamin K constitutes the antidote for overdosing of warfarin. "Our results therefore link the two worlds of ferroptosis research and vitamin K biology. They will serve as the stepping stone for the development of novel therapeutic strategies for diseases where ferroptosis has been implicated," Dr. Marcus Conrad highlighted. In addition, since ferroptosis most likely constitutes one of the oldest types of cell death, the researchers hypothesize that vitamin K might be one of the most ancient types of naturally occurring antioxidants. "Thus, new aspects of the role of vitamin K throughout the evolution of life are expected to be unveiled," Dr. Marcus Conrad explained.

The research was published in Nature.

Could you please stop telling everyone how old you are in every post you reply to. It gets old.

I'll need to see ID for everyone in this car. Registration and proof of insurance, too.

No sir. I was 81 last year. And 80 in 2020 when Biden won by hiding in his Basement it was a smart move by Biden. If voters had seen how senile and lefty liberal he was, he would have lost.

Only reason I mention my age is because I want all freezers to follow my health habits and live longer than lefty liberals. If I can do ballet dancing at 82, it proves daily aerobic 30 minute exercise is better than any vitamins, better than any nutrition supplements. I picked up daily exercise habit at age 59 to try to cure so many health issues I had and was forced to retire from a secure high paying job with government. Now I have zero health issues and age 100 in good health and with ample energy looks possible. Have a blessed day.

Started taking vitamin K a few months ago after I read an article here on FR showing it was producing positive results in mice with brain function.

Get your D3 tested. Shoot for 75 ng/ml. You get there by taking 10000 D3 daily. And it costs $2 less than last year. Or take one every other day to make it 5000 D3 daily

If I get to 90 ng/ml that’s OK with me. But my last test came in at 75
