A Method to Visualize Cell Proliferation of <i>Arabidopsis thaliana</i>: A Case Study of the Root Apical Meristem. [PDF]
Plant DirectABSTRACT Plant growth and development rely on a delicate balance between cell proliferation and cell differentiation. The root apical meristem (RAM) of Arabidopsis thaliana is an excellent model to study the cell cycle due to the coordinated relationship between nucleus shape and cell size at each stage, allowing for precise estimation of the cell ...

Meta‐analysis of genome‐wide DNA methylation and integrative omics of age in human skeletal muscle
Journal of Cachexia, Sarcopenia and Muscle, Volume 12, Issue 4, Page 1064-1078, August 2021., 2021 Abstract Background Knowledge of age‐related DNA methylation changes in skeletal muscle is limited, yet this tissue is severely affected by ageing in humans. Methods We conducted a large‐scale epigenome‐wide association study meta‐analysis of age in human skeletal muscle from 10 studies (total n = 908 muscle methylomes from men and women aged 18–89 ...
