Vitamin B12 status and folic acid supplementation influence mitochondrial heteroplasmy levels in mice.

One-carbon metabolism is a complex network of metabolic reactions that are essential for cellular function including DNA synthesis. Vitamin B12 and folate are micronutrients that are utilized in this pathway and their deficiency can result in the perturbation of one-carbon metabolism and subsequent perturbations in DNA replication and repair. This effect has been well characterized in nuclear DNA but to date, mitochondrial DNA (mtDNA) has not been investigated extensively.

Mito-SiPE is a sequence-independent and PCR-free mtDNA enrichment method for accurate ultra-deep mitochondrial sequencing.

The analysis of somatic variation in the mitochondrial genome requires deep sequencing of mitochondrial DNA. This is ordinarily achieved by selective enrichment methods, such as PCR amplification or probe hybridization. These methods can introduce bias and are prone to contamination by nuclear-mitochondrial sequences (NUMTs), elements that can introduce artefacts into heteroplasmy analysis.

How Should Allopathic Physicians Respond to Native American Patients Hesitant About Allopathic Medicine?

American Indian (AI) and Indigenous peoples utilize traditional medicine/healing (TM/H) for health and well-being. Allopathic health care practitioners (HCPs) receive minimal training and education on TM/H and its application and integration into health care settings. Lack of knowledge and practice guidelines on how to navigate these 2 health care perspectives (allopathic and traditional) creates uncertainties in the treatment of AI and Indigenous peoples.
