Ancestry dependent balancing selection of placental dysferlin at high-altitude

Autor: William E. Gundling, Sasha Post, Nicholas P. Illsley, Lourdes Echalar, Stacy Zamudio, Derek E. Wildman

Publikováno v: Frontiers in Cell and Developmental Biology, Vol 11 (2023)

Introduction: The placenta mediates fetal growth by regulating gas and nutrient exchange between the mother and the fetus. The cell type in the placenta where this nutrient exchange occurs is called the syncytiotrophoblast, which is the barrier betwe

Hypoglycemia and the origin of hypoxia-induced reduction in human fetal growth.

Autor: Stacy Zamudio, Tatiana Torricos, Ewa Fik, Maria Oyala, Lourdes Echalar, Janet Pullockaran, Emily Tutino, Brittney Martin, Sonia Belliappa, Elfride Balanza, Nicholas P Illsley

Publikováno v: PLoS ONE, Vol 5, Iss 1, p e8551 (2010)

The most well known reproductive consequence of residence at high altitude (HA >2700 m) is reduction in fetal growth. Reduced fetoplacental oxygenation is an underlying cause of pregnancy pathologies, including intrauterine growth restriction and pre

Prevalence of Trypanosoma cruzi infection in blood banks of seven departments of Bolivia

Autor: Roxana Carrasco, Hortensia Miguez, Clara Camacho, Lourdes Echalar, Suzana Revollo, Tania Ampuero, Jean-Pierre Dedet

Publikováno v: Memorias do Instituto Oswaldo Cruz, Vol 85, Iss 1, Pp 69-73 (1990)

Trypanosoma cruzi infection was studied in 1,298 sera samples of blood banks from 7 capital departments of Bolivia, using the immunofluorescence test (IFI) and Enzyme Linked Immunosorbent Assay (Elisa). The percentages of positivity in these 7 depart

DNA Methylation Explains a Subset of Placental Gene Expression Differences Based on Ancestry and Altitude

Autor: Stacy Zamudio, N.P. Illsley, Priyadarshini Pantham, Derek E. Wildman, Lourdes Echalar, William E. Gundling

Objectives: The most pronounced effect of high altitude (>2700m) on reproductive outcomes is reduced birth weight. Indigenous Bolivians (Andean Native Americans) residing for generations at high altitudes have higher birth weights relative to more re

Where the O2goes to: preservation of human fetal oxygen delivery and consumption at high altitude

Autor: Enrique Vargas, Caitlin Dolan, Tatiana Torricos, Elfride Balanza, Wilma Tellez, Michael Brimacombe, Gladys Heredia, Lourdes Echalar, Nicholas P. Illsley, Ivan Maldonado, Lucrecia Postigo, Stacy Zamudio

Publikováno v: The Journal of Physiology. 587:693-708

Fetal growth is decreased at high altitude (> 2700 m). We hypothesized that variation in fetal O2 delivery might account for both the altitude effect and the relative preservation of fetal growth in multigenerational natives to high altitude. Partici

Maternal oxygen delivery is not related to altitude- and ancestry-associated differences in human fetal growth

Autor: Gladys Heredia, Tatiana Alvarez, Lourdes Echalar, Elfride Balanza, Tatiana Torricos, Ivan Maldonado, Nicholas P. Illsley, Carmelo Rodriguez, Julio Ameller, Wilma Tellez, Stacy Zamudio, Lucrecia Postigo, Enrique Vargas, Michael Brimacombe

Publikováno v: The Journal of Physiology. 582:883-895

Fetal growth is reduced at high altitude, but the decrease is less among long-resident populations. We hypothesized that greater maternal uteroplacental O2 delivery would explain increased fetal growth in Andean natives versus European migrants to hi

Evidence for extraplacental sources of circulating angiogenic growth effectors in human pregnancy

Autor: Tatiana Torricos, Olga A. Kovalenko, A. Al-Khan, Lourdes Echalar, Manuel Jesús Parodi Álvarez, N.P. Illsley, Stacy Zamudio

Pregnancy complications such as preeclampsia (PE) and intrauterine growth restriction (IUGR) are associated with reduced blood flow, contributing to placental and fetal hypoxia. Placental hypoxia is thought to cause altered production of angiogenic g
