Insights into transgenerational epigenetics from studies of ciliates

Insights into transgenerational epigenetics from studies of ciliates SUMMARY: This article summarizes what we know about ciliate epigenetics so far. The first section is an introduction to their weird nucleus situation: ciliates have two types of nuclei, the macronucleus and the micronucleus. Several examples of ciliate epigenetics are given in sections 2 and 3. Some… Continue reading Insights into transgenerational epigenetics from studies of ciliates

Air Pollution, Early Life Microbiome, and Development

Air Pollution, Early Life Microbiome, and Development SUMMARY: This is a short review of how environmental factors during pregnancy could possibly affect the baby’s development after birth. Effects include being more prone to allergies, obesity, and autism. Many of the results turned out to be inconclusive. The authors give the following reasons: gut microbiota changes… Continue reading Air Pollution, Early Life Microbiome, and Development

Variation in the human immune system is largely driven by non-heritable influences

Variation in the human immune system is largely driven by non-heritable influences SUMMARY: This study was a twin study. The researchers looked at different elements of the immune system: T-cells, NK cells, B-cells, cytokines, etc. and saw that the development of these cells were influenced by non-heritable factors such as the environment and random epigenetic… Continue reading Variation in the human immune system is largely driven by non-heritable influences

Effects of Fat Loss on Inflammation

Substantial fat mass loss reduces low-grade inflammation and induces positive alteration in cardiometabolic factors in normal-weight individuals SUMMARY: This study looked at “normal weight female physique athletes” and how weight loss (specifically loss of visceral fat) decreased inflammation and increased enzymes that were beneficial for cardiovascular health. Results showed that weight loss upregulated genes that… Continue reading Effects of Fat Loss on Inflammation

How the Microbiome Can Change Brain Development

Early Disruption of the Microbiome Leading to Decreased Antioxidant Capacity and Epigenetic Changes: Implications for the Rise in Autism SUMMARY: This is a rather long, but very interesting, article about all the ways gut microbiome can be disrupted. The products of the the gut microbiome can affect brain development, but the article also focuses on… Continue reading How the Microbiome Can Change Brain Development
