Characterization Of Adipocyte Mechanical Properties And Stretch Control Of Mechanosignaling In Adipocytes, Tasneem Bouzid

Dissertations and Doctoral Documents from University of Nebraska-Lincoln, 2023–

Obesity has reached global epidemic levels in recent decades and is the leading risk factor for type-2 diabetes (T2D). Adipose tissue behaves as a link between obesity and T2D, with dysfunctional extracellular matrix (ECM) remodeling, adipokine secretion and lipid metabolism leading to insulin resistance. The extracellular mechanophysical milieus is understood to regulate adipocyte differentiation and function through activation of mechanosensory machinery and related pathways. Therefore, exploring the adipocytic response to mechanical loading can provide great pathophysiological insight into obesity and T2D. Adipose tissue is exposed to various compound forces due to weight-bearing and movement, and adipocyte stiffness influences stress distribution …
