...ections. Likewise, adding proBDNF to hippocampal sections deficient in tPA failed to bring about L-LTP. These experiments showed that both plasminogen and tPA are needed to bring about L-LTP. "Our study has provided a link between these two seemingly unrelated molecule systems in L-LTP," Dr. Lu said...S1P1 essential for tumor growth and is blocked by RNA interference
...ith Lewis lung carcinoma cells and examined tissue sections for S1P1 expression. S1P1 expression was found in the blood vessels only in the areas around the implanted tumor. The researchers then developed an RNA interference technique, a method that specifically blocks S1P1 expression. They showed that using...Crucial evolutionary link points to origins of modern cells

... of evolution, Groisman explains, these regulatory sections appear to take up larger portions of the DNA, allowing genes to be turned on and off in ways that are more intricately responsive to the environment and other factors. Human DNA, Groisman speculates, may be heavily packed with the factors that allow ...Researchers reconstruct parts of the genome of a common mammalian ancestor
... By examining which individual nucleotides and sections of DNA have changed and which have remained the same, geneticists can draw conclusions about which parts of our DNA are essential to the functioning of life. "Evolution is our laboratory," said Haussler. "Regions of the genome that have very importan...Wolfgang Heckl awarded Descartes Prize for Science Communication
