Fify-seven Huichol Indians with a lifelong individual history and a 1,600-year cultural tradition of ingestion of peyote, a mescaline-containing cactus possessing hallucinogenic properties, were compared with 50 Huichol Indian controls and ten laboratory controls for effects on lymphocyte chromosomes. The frequency of abnormalities in the experimental and control groups did not differ significantly. Our results indicate that multigenerational ingestion of peyote is not associated with abnormalities in lymphocyte chromosomes.

Population diversity of three variants of the SLC47A2 gene (MATE2-K transporter) in Mexican Mestizos and Native Americans.

Background: MATE2-K is an efflux transporter protein of organic cation expressed mainly in the kidney and encoded by the SLC47A2 gene. Different variants of this gene have shown an impact on the pharmacokinetics of various drugs, including metformin, which represents one of the most widely used drugs in treating type 2 diabetes. The SLC47A2 gene variants have been scarcely studied in Mexican populations, especially in Native American groups.

Introduction: Along the Mesoamerican western margin, the Zacapu basin has yielded a large number of human remains demonstrating usage of artificial cranial modification (ACM). However, at the onset of the Middle Postclassic (1200-1400 AD) only few individuals still exhibit clear signs of ACM. Some authors have suggested that, rather than disappearing entirely, ACM may have become less visible anatomically, making it difficult to identify based on simple visual analyses.

Objective: To determine the number of micronuclei and nuclear anomalies in Mexico's indigenous population.
Materials And Methods: One hundred twenty indigenous individuals were evaluated, including thirty from the ethnicities Cora, Huichol, Tarahumara and Tepehuano. The number of micronuclei (MN) and any nuclear abnormality (NA) in oral mucosa cells, including cells with nuclear buds, binucleated cells, cells with karyolysis, karyorrhetic, condensed chromatin and pyknotic cells were determined for each participant.

Background: Mexico has an ancient tradition of alcohol drinking influenced by genetic and sociocultural factors. This study aimed to determine the distribution of the DRD2/ANKK1 TaqIA polymorphism in Mexican populations and to analyze its association with heavy drinking.
Methods: In a cross-sectional and analytical study, 680 unrelated subjects including two Native Amerindians groups (87 Nahuas and 139 Huicholes), and two Mestizos groups (158 subjects from Tepic, Nayarit and 296 subjects from Guadalajara, Jalisco) were enrolled.
