Summary

Background:

Nicotinamide riboside (NR) is a vitamin B3 dietary supplement. It may help improve muscle function, that may in turn may improve a person s exercise capacity. Researchers want to study how skeletal muscle responds to NR in an individual who has Li-Fraumeni Syndrome and slow muscle energy recovery after exercise.

Objective:

To study how nicotinamide riboside affects skeletal muscle after exercise.

Eligibility:

One person at least 18 years old with Li-Fraumeni syndrome and a certain gene mutation

Design:

The participant will be screened with a medical history, physical exam, and blood and urine tests.

The participant may also have a heart test.

The participant will maintain their regular diet and supplements during the study.

The participant will take the study drug as 1-4 tablets twice a day for 12 weeks. The participant may be contacted with reminders and questions about side effects.

The participant will have 4-5 visits over 18-30 weeks. At visits, the participant will repeat screening tests. At some visits they will also have:

* Ultrasound of the heart with a wand placed on the chest.
* Test of oxygen used at rest and exercise, while wearing a face mask.
* Exercise test on a treadmill or bicycle with electrodes on the skin.
* Magnetic resonance spectroscopy. The participant will have no caffeine for 12 hours. Then they will lie in a machine for about 2 hours. Sometimes they will lie still. Sometimes they will be asked to move.

Health questionnaire

The participant may have a skin sample taken by needle.

The participant will be withdrawn from the study if they become pregnant.

Conditions

  • Cancer
  • Skin Fibroblasts
  • Muscle Weakness

Interventions

DIETARY_SUPPLEMENT

Nicotinamide Riboside (NR)

Niacin is a form of vitamin B3 and has been used to treat hypercholesterolemia for many years. There is growing evidence that nicotinamide adenine dinucleotide (NAD+ can maintain mitochondria through various mechanisms and that it is possible to improve mitochondrial function by dietary supplementation with the vitamin B3 analogue nicotinamide riboside (NR), an intermediate in the NAD+ salvage pathway. We have observed that culturing the fibroblasts of a LFS patient with mitochondrial deficiency in medium containing NR rescues the defect in mitochondrial respiration.
