Cytoskeleton Integrity refers to the robust, functional, and structurally sound state of the complex network of protein filaments—microfilaments, intermediate filaments, and microtubules—that provides mechanical support and organization to the cell. Maintaining this integrity is paramount for cellular processes such as cell division, motility, intracellular transport, and the crucial ability of cells to sense and respond to their mechanical environment. In hormonal health, its proper function is vital for receptor presentation and signal transduction efficiency.
Origin
The term combines ‘cytoskeleton,’ derived from the Greek ‘cyto’ (cell) and ‘skeleton’ (framework), with ‘integrity,’ denoting completeness and soundness. This concept is foundational to cell biology, acknowledging that the cell is not a simple fluid bag but a highly organized, mechanically active structure. The focus on integrity highlights the clinical relevance of its vulnerability to damage from oxidative stress or nutrient deficiencies.
Mechanism
The mechanism of integrity is maintained by the dynamic assembly and disassembly of its protein components, which allows the cell to change shape and move while resisting external forces. Hormones can influence this network; for example, certain steroids modulate actin filament dynamics, thereby altering cell shape and function. When integrity is compromised, cellular mechanotransduction fails, leading to impaired cellular signaling, reduced hormonal responsiveness, and ultimately, cellular senescence or apoptosis.
