Origins
MiRNA seems to generally to be found in different cell types, enriched in neuronal as well as normal and malignant hematopoietic cells and tissues.
The presence of miR-19 has been detected in a diverse range of vertebrate animals including green anole (Anolis carolinensis), primates (gorilla, human,…), cattle (Bos taurus), dog, chinese hamster (Cricetulus griseus), zebrafish (Danio rerio), horse (Equus caballus), Takifugu rubripes,Tetraodon nigroviridis, chicken (Gallus gallus), gray short-tailed opossum (Monodelphis domestica), platypus (Ornithorhynchus anatinus), Japanese medaka (Oryzias latipes), Xenopus laevis (frog), Tasmanian devil (Sarcophilus harrisii), pig (Sus scrofa) and Zebra Finch (Taeniopygia guttata).
In some of these species the presence of miR-19 has been shown experimentally, in others the genes encoding miR-19 have been predicted computationally.

Famous quotes containing the word origins:
“The settlement of America had its origins in the unsettlement of Europe. America came into existence when the European was already so distant from the ancient ideas and ways of his birthplace that the whole span of the Atlantic did not widen the gulf.”
—Lewis Mumford (1895–1990)
“Compare the history of the novel to that of rock ‘n’ roll. Both started out a minority taste, became a mass taste, and then splintered into several subgenres. Both have been the typical cultural expressions of classes and epochs. Both started out aggressively fighting for their share of attention, novels attacking the drama, the tract, and the poem, rock attacking jazz and pop and rolling over classical music.”
—W. T. Lhamon, U.S. educator, critic. “Material Differences,” Deliberate Speed: The Origins of a Cultural Style in the American 1950s, Smithsonian (1990)
“The origins of clothing are not practical. They are mystical and erotic. The primitive man in the wolf-pelt was not keeping dry; he was saying: “Look what I killed. Aren’t I the best?””
—Katharine Hamnett (b. 1948)
