The origins of lactase persistence in Europe. [PDF]

PLoS Computational Biology, 2009
Lactase persistence (LP) is common among people of European ancestry, but with the exception of some African, Middle Eastern and southern Asian groups, is rare or absent elsewhere in the world.

Meta-analysis of lactase phenotypes on obesity, metabolic syndrome and milk consumption [PDF]

BMJ Nutrition, Prevention & Health
Background The variability in lactose digestion ability is categorised into lactase persistence and lactase non-persistence phenotypes, primarily determined by the 13 910 C>T single nucleotide polymorphism (rs4988235).

Characterization of putative mannoprotein in Kluyveromyces lactis for lactase production

Synthetic and Systems Biotechnology, 2023
Lactase is a member of the β-galactosidase family of enzymes that can hydrolyze lactose into galactose and glucose. However, extracellular lactase production was still restricted to the process of cell lysis.

Community based countrywide analysis of lactase persistence related genetic variants and their correlation with digestive symptoms in Libya. [PDF]

PLOS Global Public Health
Lactose intolerance is a complex symptomatic response to lactose maldigestion that is influenced by, but not strictly determined by, the down- regulation of the enzyme lactase.

Enzyme-Loaded Liposomal Edible Hydrogel Films to Enhance Lactase Activity in Perline Mozzarella [PDF]

Gels
Lactase enzyme-based products experience challenges including residual lactose that result in lactose intolerance. The purpose of this study was to develop polyelectrolyte polysaccharide-enriched lactase-encapsulated liposomal hydrogel films as an edible

Immobilization of enzymes for synergy in polymers to produce lactose free milk [PDF]

Scientific Reports
Stabilization of the enzyme lactase is of interest in obtaining lactose-free foods. Optimization of the lactase enzyme activity was investigated using various immobilization methods, including encapsulation, and electrospinning.

Baohe pill decoction treats diarrhea induced by high-fat and high-protein diet by regulating lactase-producing bacteria in intestinal mucosa

Frontiers in Microbiology, 2023
IntroductionThis study aimed to investigate the effects of Baohe pill decoction (BPD) on microbial, lactase activity, and lactase-producing bacteria in the intestinal mucosa of mice with diarrhea induced by high-fat and high-protein diet (HFHPD ...

Ancient DNA analysis reveals high frequency of European lactase persistence allele (T-13910) in medieval central europe. [PDF]

PLoS ONE, 2014
Ruminant milk and dairy products are important food resources in many European, African, and Middle Eastern societies. These regions are also associated with derived genetic variants for lactase persistence.

Ileal Lactase Expression Associates with Lactase Persistence Genotypes

Nutrients, 2021
(1) Background: Lactose digestion depends on persistence genotypes (including rs4988235), the frequency of which exhibits broad geographical variability. However, little is known about the relationship between lactase (LCT) genotypes and intestinal expression of LCT.
