Epigenetics
¿What is epigenetics?
Epigenetics studies (gene expression), how genes turn on or off without changing the DNA itself
-
My Example
Epigenetics is like adding sticky notes or highlighting certain sections to determine how the instructions are followed
Key mechanisms
-
Histone Modification
Modifications (acetylation, methylation) affect chromatin structure and gene accessibility
-
Gene expresion
-
Environmental triggers (diet, stress, exercise) can shape epigenetic patterns
-
Bariatic surgery
-
Alters DNA methylation patterns in genes related to metabolism, inflammation, and obesity
Results in changes in gene expression that contribute to long-term weight loss and improved metabolic health
