Normal chromosome ends elicit a limited DNA damage response
Researchers at the Salk Institute for Biological Studies discovered that cells co-opted the machinery that usually repairs broken strands of DNA to protect the integrity of chromosomes. This finding solves for the first time an important question that has long puzzled scientists. The natural ends of chromosomes look just like broken strands of DNA that a cell's repair machinery is designed...Changes to embryos can elicit change in adult fish
In a study illustrating the apparent linkages between the evolutionary development and embryonic development of species, researchers have uncovered the genetic elements that determine the structure and function of a simple biomechanical system, the lower jaw of the cichlid fish. In addition, they've shown that increasing expression of a particular gene in an embryo can lead to physical changes in...One signal elicits thousands of answers
Cell signaling mechanisms often transmit information via protein modifications, most importantly the reversible attachment of phosphate, the so-called protein phosphorylation. Researchers at the Max Planck Institute of Biochemistry in Martinsried have now developed a technology to identify and quantify the specific sites in proteins that get phosphorylated in answer to certain stimuli in living c...Fire department stem cell donors felicitated with 'Honor Roll of Life'
Two Fire Department City of New York fire fighters will be honored with “Honor Roll of Life” for donating their bone marrow cells for saving Leukemia patients. The two Fire fighters John Jensen and Joe Kazlauskas donated their stem cells from bone marrow for treatment // of two leukemia patients which helped to save their life. The fire department is very proud in helping human lives as...
