To study the effects of DNMT inhibitors, histologists often use techniques such as immunohistochemistry, which allows for the visualization of specific proteins within tissue sections. By examining the expression of proteins involved in cell cycle regulation, apoptosis, and differentiation, researchers can assess the impact of DNMT inhibition on cellular behavior. Additionally, histological staining techniques, such as hematoxylin and eosin (H&E) staining, can be used to observe changes in tissue architecture and cellular morphology.
