Utilising renal ultrasound insonation augment

项目摘要

This project will utilise a versatile ultrasound insonation system, comprising two high power single-element ultrasound transducers (1MHz unfocussed and 3.5MHz focussed) driven by an RF power amplifier and function generator. This novel technological application will be combined with the intravenous administration of both commercially available microbubbles or microbubbles developed in-house and used to determine whether perturbing a targeted organ (the kidney) can induce the release of microRNA molecules that provide important information regarding the the nature and structure of the organ. Following optimisation of the ultrasound insonation system and microbubble administration, experiments will determine which microRNA molecules are increased in the circulation or urine following perturbation of the normal kidney. Experiments will also use in situ hybridisation and flow cytometric cell sorting to define the cells of origin of the released microRNA molecules. Work will then be undertaken to examine the nature and cellular source of microRNA molecules released into the circulation from injured abnormal kidneys. This project will use the kidney as an exemplar organ and will develop and refine a new platform technology that may be used to interrogate the function and structure of other abdominal organs accessible to ultrasound as well as other tissues such as muscle etc.

该项目将利用多功能超声超声系统，包括两个高功率单元件超声换能器（1MHz非聚焦和3.5MHz聚焦），由射频功率放大器和函数发生器驱动。这种新颖的技术应用将与市售微泡或内部开发的微泡静脉给药相结合，用于确定干扰目标器官（肾脏）是否可以诱导microRNA分子的释放，从而提供有关器官性质和结构的重要信息。在优化超声系统和微泡给药后，实验将确定在正常肾脏受到干扰后，哪些microRNA分子在循环或尿液中增加。实验还将使用原位杂交和流式细胞术细胞分选来确定释放的microRNA分子的细胞来源。随后将开展工作，以检查从受损的异常肾脏释放到循环中的microRNA分子的性质和细胞来源。该项目将以肾脏为样本器官，并将开发和完善一种新的平台技术，该技术可用于询问其他腹部器官以及其他组织（如肌肉等）的功能和结构。
