Module 10 EN Welcome to your Module 10 EN Environmental epigenetics studies based on simple epidemiological models are sufficient to conclusively prove a causal link between air pollution and epigenetic changes. TRUE FALSE None Why is studying DNA methylation alone insufficient for understanding exposure-related effects? DNA methylation is only relevant in early development. DNA methylation is one of many epigenetic modifications and cannot fully explain exposure-related effects on its own. Other epigenetic modifications do not influence gene expression. DNA methylation does not change in response to environmental exposures. None Epigenetic changes occur by altering the DNA sequence itself, leading to permanent genetic mutations. TRUE FALSE None Epigenetic differences play only a minor role in individual responses to air pollution, making them irrelevant for identifying at-risk populations or guiding public health policies. FALSE TRUE None Population study design and controlled crossover exposure studies are two study designs that can be used to study the effects of air pollution on DNAm. TRUE FALSE None Exposure to pollutants like nickel, arsenic, iron, and polyaromatic hydrocarbons alters histone methylation and acetylation. FALSE TRUE None What advantages does GWIS have over GWAS? Homogeneity between studies Simple exposure assessment It explores GxE interactions in studies where exposure information is available Small sample requirements None Epidemiological-land use regression (LUR) study design compares people living in high- and low-pollution areas, such as industrial vs. rural regions. TRUE FALSE None Which of the following methods is promising for studying the epigenetic alterations induced by particulate matter (PM) exposure? Gene knockdown experiments DNA methylation profiling and histone modification analysis Protein structure analysis RNA sequencing None Large population studies on how air pollution affects histone modifications are abundant and well-established.
