Measurement of Oxygen Consumption Rate (OCR) and Extracellular Acidification Rate (ECAR) in Culture Cells for Assessment of the Energy Metabolism 测定培养细胞中的消氧率(OCR)和细胞外酸化率(ECAR)以评估能量代谢 作者:Birte Plitzko and Sandra Loesgen日期:05/20/2018,浏览量:59814,Q&A: 1
Mammalian cells generate ATP by mitochondrial (oxidative phosphorylation) and non-mitochondrial (glycolysis) metabolism. Cancer cells are known to reprogram their metabolism using different strategies to meet energetic and anabolic needs (Koppenol et al., 2011; Zheng, 2012). Additionally, each cancer tissue has its own individual ...

Ex vivo Follicle Rupture and in situ Zymography in Drosophila 果蝇离体卵泡破裂和原位酶谱 作者:Elizabeth M Knapp, Lylah D Deady and Jianjun Sun日期:05/20/2018,浏览量:5317,Q&A: 0
Ovulation, the process of releasing a mature oocyte from the ovary, is crucial for animal reproduction. In order for the process of ovulation to occur, a follicle must be fully matured and signaled to rupture from the ovary. During follicle rupture in both mammals and Drosophila, somatic follicle cells are enzymatically degraded to allow ...
