Abstract

Onset expression of Type 2 (NIDDM) diabetes and obesity metabolic syndromes (DOS) are characterized by premature, progressive cytoatrophy and organo-involution induced by dysregulated cellular gluco- and lipo-metabolic cascades. The consequential systemic, interstitial and intracellular hyperlipidemia disrupts normal cytointegrity and metabolic responsivity to the established hypercaloric pericellular environments. The sequential cytostructural, metabolic and endocrine disturbances associated with the development of progressive DOS-associated hypercytolipidemia compromises cellular metabolic response cascades and promotes cytochemical disturbances which culminate with nuclear lipoapoptosis and cytoatrophy. The dramatic alterations in interstitial glucose and lipid (free fatty acids/triglycerides) concentrations are recognized to influence interstitial and cytoplasmic microchemical environments, which markedly alter cellular nutrient diffusion and active trans-membrane flux rates. The progressive exacerbation of interstitial and cytoplasmic lipid imbibition has been demonstrated to be associated with DNA fragmentation by lipo-infiltration into the chromatin matrix, inducing structural disruption and physical dissolution, indexed as nuclear lipoapoptosis. Therapeutic reduction of the severity of hypercytolipidemia-induced structural and cytochemical compromise promotes the restoration of homeostatic metabolic support for normalized cytostructural indices and supportive cellular gluco- and lipo-metabolic cascades. The re-establishment of a homeostatic interstitial microenvironment moderates the severity of cytolipidemic compromise within affected cell types, reduces nuclear lipo-infiltration and DNA lipo-dissolution, resulting in the preservation of cytostructural integrity. Through the therapeutic restoration of extra- and intra-cellular microchemical environments in genetically dysregulated metabolic syndrome models, the coincident cytochemical, endocrine and metabolic disturbances associated with progressive hypercytolipidemia, resulting from the expressed systemic hypercaloric environmental and hepato-pancreatic endometabolic disturbances which characterize Type 2 (NIDDM) diabetes-obesity and metabolic (X) syndromes, may be ameliorated.

摘要

2型(非胰岛素依赖型糖尿病)糖尿病和肥胖代谢综合征(DOS)的发病表现特征为,细胞葡萄糖和脂质代谢级联失调引发的过早、进行性细胞萎缩和器官退化。随之而来的全身性、间质和细胞内高脂血症会破坏正常的细胞完整性以及对既定高热量细胞周围环境的代谢反应能力。与进行性DOS相关的高脂血症发展相关的一系列细胞结构、代谢和内分泌紊乱,损害了细胞代谢反应级联,并促进了细胞化学紊乱,最终导致核脂质凋亡和细胞萎缩。间质葡萄糖和脂质(游离脂肪酸/甘油三酯)浓度的显著变化被认为会影响间质和细胞质微化学环境,从而显著改变细胞营养物质扩散和主动跨膜通量速率。间质和细胞质脂质摄取的进行性加重已被证明与脂质浸润染色质基质导致的DNA片段化有关,从而诱导结构破坏和物理溶解,即核脂质凋亡。治疗性降低高脂血症引起的结构和细胞化学损害的严重程度,有助于恢复对正常细胞结构指标以及支持性细胞葡萄糖和脂质代谢级联的稳态代谢支持。稳态间质微环境的重建可减轻受影响细胞类型内脂质血症损害的严重程度,减少核脂质浸润和DNA脂质溶解,从而保持细胞结构完整性。通过在基因失调的代谢综合征模型中治疗性恢复细胞外和细胞内微化学环境,与进行性高脂血症相关的同时发生的细胞化学、内分泌和代谢紊乱,可能会得到改善。这些紊乱是由2型(非胰岛素依赖型糖尿病)糖尿病-肥胖和代谢(X)综合征所特有的全身性高热量环境以及肝胰内代谢紊乱所导致的。
