Inverse Association Between Serum Vitamin B12 Concentration and Obesity Among Adults in the United States

Frontiers in Endocrinology, 2019
Introduction: Several studies have suggested that vitamin B12 deficiency is more common in obese individuals. We evaluated the cross-sectional associations of serum vitamin B12 concentrations with obesity in a nationally representative sample of adults ...

Developing HaloTag and SNAP‐Tag Chemical Inducers of Dimerization to Probe Receptor Oligomerization and Downstream Signaling

Angewandte Chemie International Edition, EarlyView.
Controlling protein interactions is key to studying signaling. Antibody methods have limits, but chemical inducers of dimerization (CIDs) using HaloTags and SNAP‐Tags offer precise control. We present CIDs to covalently link heteromers with varied linkers and a FRET‐based sensor.

Metabolic engineering of Escherichia coli for de novo biosynthesis of vitamin B12

bioRxiv, 2018
The only known source of vitamin B12 (adenosylcobalamin) is from bacteria and archaea. Here, using genetic and metabolic engineering, we generate an Escherichia coli strain that produces vitamin B12 via an engineered de novo aerobic biosynthetic pathway.

Vitamin B12 Status Upon Short-Term Intervention with a Vegan Diet—A Randomized Controlled Trial in Healthy Participants

Nutrients, 2019
Vegans are at an increased risk for certain micronutrient deficiencies, foremost of vitamin B12. Little is known about the short-term effects of dietary change to plant-based nutrition on vitamin B12 metabolism. Systemic biomarkers of vitamin B12 status,

Dual Functions of Dietary Rubber Seed Oil Supplementation: Enriching N‐3 Polyunsaturated Fatty Acids and Enhancing Antioxidant Capacity in Pekin Ducks

Animal Research and One Health, EarlyView.
Dietary RSO supplementation improved growth performance, simultaneously enriched n‐3 polyunsaturated fatty acids (n‐3 PUFA), and enhanced antioxidant capacity in Pekin ducks, which suggested that RSO has the potential to be a novel n‐3 PUFA source and an antioxidant for Pekin ducks to generate animal functional foods.

Blood Concentrations of Homocysteine and Methylmalonic Acid among Demented and Non-Demented Swedish Elderly with and without Home Care Services and Vitamin B12 Prescriptions

Dementia and Geriatric Cognitive Disorders Extra, 2012
Background and Aims: Total plasma homocysteine (tHcy) has been suggested as a risk factor of dementia. Our aim was to investigate potential differences in tHcy status in relation to the prescription of vitamin B12 and dementia diagnosis.

Is high vitamin B12 status a cause of lung cancer?

International Journal of Cancer, 2019
Vitamin B supplementation can have side effects for human health, including cancer risk. We aimed to elucidate the role of vitamin B12 in lung cancer etiology via direct measurements of pre‐diagnostic circulating vitamin B12 concentrations in a nested ...
