Mechanical force regulates a variety of cellular functions through inducing modulations in nuclear chromatin structures and epigenetic landscapes(outside in). The epigenetic modifications, in turn,regulate gene expressions and affect phenotypic outcomes, including cytoskeletal organization and cell–cell/cell–ECM interactions(inside out). While there have been significant advances in the understanding of mechanotransduction in the nucleus, there is still a lack of knowledge on the potential mechanisms through which mechanical cues affect epigenetic and chromatin regulations to determine genetic outcomes. This review firstly focuses on the current understanding of epigenetic regulations and then summarizes how mechanotransduction and epigenetic modification couple together to regulate molecular and cellular functions, eventually causing functional phenotype changes e.g., ***, we introduce related technologies for mechanistic studies, particularly fluorescence resonance energy transfer(FRET) biosensors for the visualization of dynamic epigenetic regulations in single living cells, as well as the applications of FRET biosensors to visualize mechanotransduction events occurring in the nucleus. These studies could provide new insights into epigenetics in regulating the physiological and pathological processes in living cells under different mechanical environments.

ASSOCIATION OF PLASMA INSULIN WITH BLOOD PRESSURE AND SODIUM SENSITIVITY IN CHILDREN

引用

Journal of Pharmaceutical Analysis 1999年第2期13卷 137-141页

作者： Mou Jianjun,Liu Zhiquan,yang dingyi) Department of Cardiovascular Internal Medicine, First Affiliated Hospital,Xi′an Medical University, Xi′an 710061 Dept. of Cardiovasc. Internal Med. First Affiliated Hospital Xi'an Medical University Xi'an 710061 China

To study the relationship between plasma insulin level, sodium sensitivity and blood pressure, 150 children aged from 10 to 15 years with higher blood pressure (HBP) and 150 children matched for age and sex but with normal blood pressure were measured for plasma insulin with radioimmunoassay and sodium sensitivity with the tests of oral saline load and furosemide sodium volume depletion and followed for 5 years. The results showed that: ①In children with HBP and positive family history of hypertension (FH +), the plasma insulin level was significantly higher than that in the respective control group (P<0 01);②In children with high plasma insulin level, the percentiles of systolic blood pressure kept high and had a rising tendency during the follow up period; ③In children with sodium sensitivity, the plasma insulin level was higher than that in children with sodium resistance (P<0 01) and the plasma insulin level correlated positively with blood pressure increasing rate of post load (P<0 05). It is suggested that insulin mediated salt and water retention may be a basic pathogenic mechanism in sodium sensitivity, and involved in the development of essential hypertension.
