By integrating new and published data on CD34+ human stem-progenitor cell transcripts, a team of American researchers have mapped a transcriptome that may offer insights into the process of blood system development.
Obama said that the US is in danger of slipping from its lead spot in science innovation and called for "a historic investment" in research and education that would fuel innovation as the GI Bill did a half-century ago.
The data demonstrate that siRNAs that are 21 nucleotides in length or longer suppress both hemangiogenesis and lymphangiogenesis in vivo, regardless of their targets or sequences, due to the activation of TLR3.
Using microarray and Northern blot analyses, Johns Hopkins University researchers discovered that the levels of almost all miRNAs increases following cell-cell contact in Drosophila and mammalian cell lines, regardless of whether these cells display contact inhibition.
A group of Atlanta researchers used a technique called desorption electrospray ionization mass spectrometry to help characterize antibacterial and antifungal compounds on the surface of a tropical red algae.
Based on comparisons between piRNA clusters in mouse, rat, and other mammalian genomes, University of Michigan researchers found evidence that piRNAs are likely under positive selection and capable of rapid expansion.
