Transcription factor helps tumors grow in low oxygen, resist anticancer therapies

Transcription factor helps tumors grow in low oxygen, resist anticancer therapies

  An international team of researchers found how cancer cells respond to DNA damage signaling when in low oxygen, or hypoxia. Through comprehensive gene expression analyses, the team determined how one family of genes controls DNA damage response, as well as how it weakens the effectiveness of anticancer therapies. Our bodies have strict molecular mechanisms that help us respond to hypoxia. These mechanisms are not just limited to helping us adapt to higher altitudes when climbing up a mountain. They also arise in diseases such as anemia, diabetes, or cancers. In the case of a new study led by Keiji Tanimoto’s team at Hiroshima University (HU), hypoxia indicates developments or… Read more

A Conversation with Distinguished Professor Hideki Ohdan Distinguished Professor Hideki Ohdan identifies himself as a “surgeon scientist.” He grew up in Hiroshima city and completed a Medical Degree in 1988 and a PhD degree in 1997, both from Hiroshima University. Now, he leads an active medical practice and research laboratory at Hiroshima University Hospital. His career has focused on removing biological barriers to match organ donors with patients who need organ transplants. This project is driven by the immediate needs of clinical patients, but involves solving a larger scientific mystery: how does the immune system recognize its own body as native cells to ignore and recognize foreign cells as invaders… Read more
