Type of Research Project
- Basic science
What is the background of the project?
Diabetes mellitus (DM) is a complicated metabolic disease with various complications, including diabetic cardiomyopathy (DCM), and is a risk factor for the development of heart failure. DCM is the major cause of mortality and morbidity in DM patients and is characterized by abnormal ventricle structure and function in diabetic patients without coronary artery disease or hypertension. Patients and animal models of DCM exhibit structural cardiac remodeling, such as ventricular hypertrophy and interstitial fibrosis, and functional impairments, including systolic and diastolic dysfunctions. Currently, there is no specific therapy for DCM patients in clinical practice despite the critical need. Increased oxidative stress, alterations of energy metabolism, and apoptotic cardiac cell death, resulting from mitochondrial dysfunction are implicated in the pathogenesis of DCM and present potential therapeutic targets.
What is the aim of the project?
The aims of present study were to study mitochondrial dysfunction involved in DCM and pharmacological and genetic rescue of mitochondria can restore cardiac function in late-stage DCM.
What techniques and methods are used?
1. Molecular biology with polymerase chain reaction (PCR), reverse transcription polymerase chain reaction PCR (RT-PCR), real-time polymerase chain reaction, and sequencing 2. Fluorescence imaging with confocal microscope and image analysis 3. Electrophysiology with patch-clamp techniques and electrophysiological data analysis 4. In vivo cardiac function validation with echocardiography and echocardiographic data analysis 5. Mitochondrial function assay: oxygen consumption data analysis 6. Animal model of exercise
What is the role of the student?
- The tasks will be done under supervision
What are the tasks expected to be accomplished by the student?
The students will be involved in the techniques and methods as below: 1. Molecular biology with polymerase chain reaction (PCR), reverse transcription polymerase chain reaction PCR (RT-PCR), real-time polymerase chain reaction, and sequencing 2. Fluorescence imaging with confocal microscope and image analysis 3. Electrophysiology with patch-clamp techniques and electrophysiological data analysis 4. In vivo cardiac function validation with echocardiography and echocardiographic data analysis 5. Mitochondrial function assay: oxygen consumption data analysis 6. Animal model of exercise They will participate in the work-in-progress and the seminars. They can get the basic concept of energy metabolism, mitochondrial physiology and cardiac physiology. He or she can participate as co-author in the experiment for mitochondrial energy metabolic derangements in heart failure (depending on his/her contribution) He/she can be one of authors of original and review articles.
Will there be any theoretical teaching provided (preliminary readings, lectures, courses, seminars etc)
Yes, there are several theoretical teaching provided as below: 1. Miracle seminar: work-in-progress and journal reading, every friday 2. Lecture: invited lecture series, monthly seminar
What is expected from the student at the end of the research exchange? What will be the general outcome of the student?
- The student will prepare a poster - The student’s name will be mentioned in a future publication - The student will have the opportunity to present the results together with the supervisor at a conference
What skills are required of the student? Is there any special knowledge or a certain level of studies needed?
Literally, basic knowledge and concept for cell physiology taught at medical schools and other majors related to biology
Are there any legal limitations in the student’s involvement
