脂肪组织和骨骼肌是对肥胖和身体活动反应强烈的器官,表现出高分泌活性。为了确定新的假定的脂肪代谢因子,将瘦肉(C57BL/6J)和肥胖(高脂饮食和NZO的C57BL/6J)小鼠、久坐和耐力训练的C57BL/6J小鼠以及肌肉内脂肪含量不同的牛的骨骼肌和脂肪组织的比较表达研究与人类分泌组数据相结合并进行评分。在高度调控的转录本中,我们鉴定出119个肌因子,79个脂肪因子和22个脂肪因子。对这些候选药物的网络分析显示,细胞外基质的重塑和组织纤维化是其中一些候选药物的相关功能。鉴于纤维化与肥胖和2型糖尿病中脂肪-肌肉交叉的病理生理相关性及其在农场动物运动适应和肉质中的生理作用,它们代表了在不同研究领域和物种中进一步研究的有趣候选者。
Abstract Adipose tissue and skeletal muscle are organs that respond strongly to obesity and physical activity exhibiting high secretory activity. To identify novel putative adipomyokines, comparative expression studies of skeletal muscle and adipose tissue of lean (C57BL/6J) and obese (C57BL/6J on a high-fat diet and NZO) mice, of sedentary and endurance trained C57BL/6J mice and of cattle characterized by different amounts of intramuscular fat were combined with human secretome data and scored. In highly regulated transcripts, we identified 119 myokines, 79 adipokines and 22 adipomyokines. Network analysis of these candidates revealed remodelling of extracellular matrix and tissue fibrosis as relevant functions of several of these candidates. Given the pathophysiogical relevance of fibrosis for adipose-muscle-cross-talk in obesity and type 2 diabetes and its physiological role in exercise adaptation and meat quality of farm animals, they represent interesting candidates for further investigations in different research areas and species.
