...nts from a distance and therefore does not need to attach itself to the plant to elicit a response. When the researchers studied L. japonicus plants missing the receptors that receive signals from other organisms certain genes in the plant were modified to accomplish this they discovered that the plants ...New binding target for oncogenic viral protein
...brings them in close proximity to the enzymes that attach ubiquitin. The proteins recognized by Fbw7 play key roles in cell division, cell growth, differentiation, and cell death. "These proteins are also some of the most broadly acting cellular oncogenes, and include cyclin E, c-Myc, Notch, and c-Jun," not...Tailing the cause of a rare heart disease
...g loss lacks a region necessary for the protein to attach to other proteins that help it enter the cell nucleus. Only if the eya4 protein enters the nucleus can it play the appropriate role in gene regulation, said Seidman. "That finding suggests that this mutation causes a dramatic reduction in the amount ...Harnessing microbes, one by one, to build a better nanoworld

Then researchers attach fluorescent labels to nucleic acids (DNA or RNA) from the cells under study. These labeled nucleic acids are allowed to bind to the DNA on the slides. Researchers then use a microscope to measure how much of a specific nucleic acid is present. Genoty...New strategies to reduce hospital-acquired infections
