Analyzing functions of molecules that control calcium
signaling in cardiac myocytes using a confocal laser scanning
  The prognoses of patients with heart diseases, such as heart failure and arrhythmia, tend to be poor. Therefore pathophysiological mechanisms and therapeutic strategies for heart diseases have been intensively studied. The heart consists of cardiac myocytes. Calcium ion (Ca2+) in cardiac myocytes plays an essential role in the regulation of cardiac function. Cardiac myocytes continue to beat by maneuvering the intracellular Ca2+. On the other hand, Ca2+ is extremely toxic to cardiac myocytes, when they lose control of it. The dysregulation of Ca2+ causes serious problems such as arrhythmia and heart failure due to ectopic excitation and contractile dysfunction, respectively. By elucidating the mechanism for fine-tuning of Ca2+ and its failure in cardiac myocytes, our laboratory is opening up novel therapeutic strategies against heart diseases.

Microfertilization using a manipulator to inject a sperm in an egg cell
Microfertilization using a manipulator to inject a sperm in an
egg cell
  While fertility treatment, such as in vitro fertilization, has made dramatic progress and is widely applied, it has been reported that the rates of disorders caused by epigenetics— that is, heritable changes in gene expression without abnormality in DNA or gene sequence—are high in children conceived by assisted reproductive technology (ART). We are elucidating the relation between epigenetics and fertility treatment with the aim of offering safer reproductive medicine, considering the long-term health of children.
  We analyze samples obtained without imposing a burden on patients or employing invasive procedures, such as samples taken from the placenta of women who gave birth as a result of fertility treatment or using culture media for fertilized eggs to study in vitro fertilization in comparison to spontaneous pregnancy. Our objective is the clarification of specific mechanisms that illuminate how and at what stage the health of children conceived by ART is affected.
