Tumor energy source found by scientists at Hiroshima University, University of Cincinnati and Keio University

Tumor energy source found by scientists at Hiroshima University, University of Cincinnati and Keio University

Original text by University of Cincinnati. Edited by Emma Buchet, Hiroshima University. UC researchers unlock cancer cells’ feeding mechanism, central to tumor growth The findings could lead to new treatments by blocking tumor growth at its roots. An international team led by researchers from the University of Cincinnati and Japan’s Keio and Hiroshima universities has… Read more

Scientists discover origin of cell mask that hides stomach cancer

Scientists discover origin of cell mask that hides stomach cancer

A layer of cells that look like normal stomach lining on top of sites of stomach cancer can make it difficult to spot after removal of a Helicobacter pylori infection. In a recent study, researchers from Hiroshima University have uncovered the origin of this layer of cells: it is produced by the cancer tissue itself…. Read more

Family dynamics: molecules from the same family have different effects in cancer prognosis

Family dynamics: molecules from the same family have different effects in cancer prognosis

Scientists observe that one molecule increases liposarcoma tumor cell spread and aggression while another molecule from the same family decreases migration and cell proliferation. Researchers at Hiroshima University have found that different levels of two molecules of the same family—TIMP-1 and TIMP-4—can influence prognosis of liposarcoma. High levels of TIMP-1 lead to a poor prognosis… Read more

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… Read more

Studying cancer DNA in blood may help personalize treatment in liver cancer

Studying cancer DNA in blood may help personalize treatment in liver cancer

  Fragments of cancer DNA circulating in a patient’s bloodstream could help doctors deliver more personalized treatment for liver cancer, Japanese researchers report. The new research may help address a particular challenge posed by liver cancers, which can be difficult to analyze safely. One serious risk of existing biopsy methods is that doctors who want… Read more
