Too Much of a Good Thing: Important Mechanism in Hormone-Sensitive Breast Cancer Uncovered

In two out of three breast tumors, extraordinarily high levels of the estrogen receptor ERá are found. Scientists of the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) have now uncovered a mechanism which causes this overproduction. This result might contribute to...

Researchers: RNA Snippet Helps Make Individuals Remarkably Alike

EVANSTON, Ill. --- “No two people are alike.” Yet when we consider the thousands of genes with frequent differences in genetic composition among different people, it is remarkable how much alike we are. Uniformity, or singleness of form, is not unique to humans but a general property...

New insights into hearing loss

Human and mouse share hearing deficit caused by mutation in microRNAIn parallel studies in human and mouse, two groups of researchers have come to the same conclusion: that a new kind of gene is associated with progressive hearing loss. The new gene - called a microRNA - is a tiny fragment of RNA...

MicroRNA undermines tumor suppression

CAMBRIDGE, Mass.  —A small piece of RNA, or microRNA (miRNA), ratchets down the activity of the tumor-suppressor gene p53, according to a study by Whitehead Institute and Genome Institute of Singapore and the Institute of Molecular and Cell Biology in Singapore.While p53 functions to...
