A secret to making macrophages (w/ Video)

Biologists at the California Institute of Technology (Caltech) have worked out the details of a mechanism that leads undifferentiated blood stem cells to become macrophages—immune cells that attack bacteria and other foreign ...

The TALE of new tools to study gene regulation

In nearly every organism's genome, scattered between genes that encode proteins, long regulatory regions stretch across expanses of DNA. Understanding what role these so-called enhancer regions play in controlling the activation ...

Scientists discover how rapamycin slows cell growth

University of Montreal researchers have discovered a novel molecular mechanism that can potentially slow the progression of some cancers and other diseases of abnormal growth. In the May 23 edition of the prestigious journal ...

Wound healing: 'See-saw' switch sends cells on the march

Many genes are transcribed into messenger RNA (mRNA) molecules that provide instructions for protein synthesis. Other genes encode regulatory RNAs known as 'microRNAs', which can block protein translation by binding to specific ...

How gold nanoparticles can help fight ovarian cancer

Positively charged gold nanoparticles are usually toxic to cells, but cancer cells somehow manage to avoid nanoparticle toxicity. Mayo Clinic researchers found out why, and determined how to make the nanoparticles effective ...
