Vitamins as potent cancer treatments through regulating the activity and expression of MMP‐2 and MMP‐9

Bulletin of the Korean Chemical Society, Volume 47, Issue 6, Page 745-755, June 2026.
Vitamins could regulate both MMP‐2 and MMP‐9 expression and activity through transcriptional and MAPK signaling pathway modulation. This study highlights the potential of vitamins as low‐toxicity therapeutic or adjunct agents for targeting MMP‐mediated cancer progression. Abstract Matrix metalloproteinases (MMP‐2 and MMP‐9) are key regulators of cancer

Analytic validation of commercially available immunoassays for the measurement of serum cobalamin and folate concentrations in pigs

, 2016
BACKGROUND Cobalamin (vitamin B12 ) and folate (vitamin B9 ) are important for the amino acid metabolism and nucleic acid synthesis. Immunoassays for the measurement of both vitamins in serum are routinely used in people, cats, and dogs, serving as ...

Severe Lactic Acidosis in Decompensated Cirrhosis Despite Nondiagnostic Imaging

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Lactic acidosis is a strong predictor of mortality in cirrhosis, reflecting both impaired hepatic clearance and systemic tissue hypoxia. We describe a 38‐year‐old man with decompensated alcohol‐associated cirrhosis who developed severe lactic acidosis despite stable hemodynamics and initially nondiagnostic vascular imaging.

Bioenhancer‐Driven Modulation of Membrane Dynamics Improves B‐Vitamin Uptake in Caco‐2 Cells

ChemFoodChem, Volume 2, Issue 2, June 2026.
Natural bioenhancers such as extracts from ginger, turmeric, black pepper, and spearmint increase the uptake of vitamins B1, B5, B6, and B7 in Caco‐2 cells. Micellized formulations further increase efficacy. These findings indicate that altered membrane fluidity contributes to enhanced cellular absorption, providing a new route to improve vitamin B ...

Association of Type 2 Diabetes Mellitus With Dietary Vitamin B12 Intake in Individuals With Different Fat Mass and Obesity‐Associated (FTO) Genotypes

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Higher dietary vitamin B12 intake was inversely associated with the odds of type 2 diabetes mellitus among individuals carrying the TT genotype of the FTO rs9939609 polymorphism. These findings highlight the potential role of precision nutrition strategies in diabetes prevention.
