Researchers discover an unexpected link between DNA winding and metabolism in the gut to ameliorate aging. Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell...

New research in mice indicates that a drug commonly used to suppress the immune system in recipients of organ transplants may also reduce tissue damage and neuropathic pain after spinal cord injury. Rapamycin, which is an inhibitor of the mammalian target of rapamycin (mTOR) signaling pathway, has a variety of cellular functions and is known to possess both immunosuppressant and anti-tumor properties. In their previous work, investigators at the Tohoku University Graduate School of Medicine in Japan found that rapamycin treatment can reduce nerve damage and locomotor impairment after spinal cord injury...

For a long time it has been known protein TOR – Target of Rapamycin – controls cell growth and is involved in the development of diseases such as cancer and diabetes. Researchers have now examined the structure of mammalian TOR complex 1 (mTORC1) in more detail.

About 25 years ago, Prof. Michael Hall discovered the protein “Target of Rapamycin” (TOR) at the Biozentrum. It is one of the most studied proteins of the protein kinase family, an important family of regulatory proteins that control many cellular processes. TOR, in mammals called mTOR, is very important for cellular signalling and is implicated in various diseases such as cancer, diabetes, and neurodegeneration...
