Evolutionary formation of melatonin and vitamin D in early life forms: insects take centre stage

open access: yesBiological Reviews, Volume 99, Issue 5, Page 1772-1790, October 2024.
ABSTRACT Melatonin, a product of tryptophan metabolism via serotonin, is a molecule with an indole backbone that is widely produced by bacteria, unicellular eukaryotic organisms, plants, fungi and all animal taxa. Aside from its role in the regulation of circadian rhythms, it has diverse biological actions including regulation of cytoprotective ...

Interaction between dietary and lifestyle risk factors and N-Acetyltransferase polymorphisms in B-Cell lymphoma etiology [PDF]

open access: yes, 2015
Background: Gene-environment interactions are suggested to play a role in lymphomagenesis. Methods: We tested the interaction between the NAT1/NAT2 phenotype, as inferred by the respective genotypes, and exposure to dietary and lifestyle risk factors ...

Sexually dimorphic traits are associated with subsistence strategy in African faces from the Sahel/Savannah belt

open access: yesAmerican Journal of Human Biology, Volume 36, Issue 4, April 2024.
Abstract Objectives Previous research revealed that in some African populations, food‐production strategies are associated with facial shape. Nomadic pastoralists living in the African Sahel/Savannah belt have a different facial morphology than their sedentary neighbors. We investigated whether the lifestyle associated with a subsistence pattern has an

The role of the human acetylation polymorphism in the metabolic activation of the food carcinogen 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) [PDF]

open access: yes, 2017
The metabolic activation of the heterocyclic food carcinogen 2-amino-3-methylimidazo[4,5-f]quinoline (IQ) by two human cytochrome P450 monooxygenases (P4501A1 and P4501A2) and two human N-acetyltransferases (NAT1 and NAT2) was investigated.

Arylamine N-Acetyltransferase 1 Regulates Expression of Matrix Metalloproteinase 9 in Breast Cancer Cells: Role of Hypoxia-Inducible Factor 1-α

open access: yesMolecular Pharmacology, 2019
Arylamine N-acetyltransferase 1 (NAT1) is a drug-metabolizing enzyme that influences cancer cell proliferation and survival. However, the mechanism for these effects is unknown. Because of previous observations that NAT1 inhibition decreases invasiveness,

Antimicrobial properties of garlic oil against human enteric bacteria: evaluation of methodologies and comparisons with garlic oil sulfides and garlic powder. [PDF]

open access: yes, 2001
The antimicrobial effects of aqueous garlic extracts are well established but those of garlic oil (GO) are little known. Methodologies for estimating the antimicrobial activity of GO were assessed and GO, GO sulfide constituents, and garlic powder (GP ...
