Post-weaning A1/A2 β-casein milk intake modulates depressive-like behavior, brain μ-opioid receptors, and the metabolome of rats [PDF]

iScience, 2021
Summary: The postnatal period is critical for brain and behavioral development and is sensitive to environmental stimuli, such as nutrition. Prevention of weaning from maternal milk was previously shown to cause depressive-like behavior in rats ...

Dietary β-casein A1 as a risk factor for the development of inflammatory processes in dogs [PDF]

Ciência Rural
: This study compared the effect of two diets, one containing A1 β-casein (test) and the other A2 β-casein (control) in dogs, analyzing inflammatory markers and blood parameters for 30 days.

Genotypic profiling of A1 and A2 β-casein alleles in Punganur cattle using PCR-RFLP [PDF]

Indian Journal of Animal Sciences
Milk is regarded as nature’s perfect food due to the presence of essential nutrients required for the growth and development of mammals. The consumption of milk with a specific β casein variant either A1 or A2 had a relationship with the risk of ...

Reproductive Neutrality of the A2 β-Casein Variant in Holstein Cows

Animals
The CSN2 gene encoding β-casein has gained increasing attention in dairy cattle breeding due to the global adoption of A2-oriented selection strategies.

Frequency of A1 and A2 alleles of the β-casein gene in cattle in the Cajamarca region of Peru [PDF]

Open Veterinary Journal
Background: Cow's milk β-casein has multiple genetic variants, the two most common of which are A1 and A2, which are encoded by the CSN2 gene. Evidence suggests that the A1 variant may negatively affect human health.

Detecting β-Casein Variation in Bovine Milk

Molecules, 2016
In bovine species, β-casein (β-CN) is characterized by genetic polymorphism. The two most common protein variants are β-CN A2 (the original one) and A1, differing from A2 for one amino acid substitution (Pro67 to His67).

GENETIC INSIGHTS INTO THE Β-CASEIN (CSN2) LOCUS IN HOLSTEIN-FRIESIANS: A STEP TOWARDS A2 MILK PRODUCTION

Trakia Journal of Sciences
Milk plays a major role as protein source in human diet. Among the casein fractions, β-casein, encoded by the CSN2 gene, is characterized by the presence of several polymorphic variants. The most predominant types in dairy cattle are A1 and

Effects of cow’s milk beta-casein variants on symptoms of milk intolerance in Chinese adults: a multicentre, randomised controlled study

Nutrition Journal, 2017
Background A major protein component of cow’s milk is β-casein. The most frequent variants in dairy herds are A1 and A2. Recent studies showed that milk containing A1 β-casein promoted intestinal inflammation and exacerbated gastrointestinal symptoms ...

Evaluating the potential impact of selection for the A2 milk allele on inbreeding and performance in Australian Holstein cattle

Frontiers in Animal Science, 2023
Selection decisions are generally based on estimated breeding values (EBV) for a combination of traits that are polygenic (e.g. milk production). However, in some cases, there is additional intense selection for a single allele, or SNP, for a perceived ...

Effects of surface passivation on gliding motility assays [PDF]

, 2010
In this study, we report differences in the observed gliding speed of microtubules dependent on the choice of bovine casein used as a surface passivator.
