History
These sequences were first discovered in 1988 in poliovirus RNA and encephalomyocarditis virus RNA in the labs of Nahum Sonenberg and Eckard Wimmer, respectively. They are described as distinct regions of RNA molecules that are able to attract the eukaryotic ribosome to the mRNA molecule and, therefore, allow translation initiation to occur. This process became known as the internal initiation of translation. It has been hypothesized that IRES elements have a distinct secondary or even tertiary structure, but similar structural features at the levels of either primary or secondary structure that are common to all IRES segments have not been reported to date.
Cancer: 5′-UTR of Laminin-B1 harbors IRES between −293 and −1 upstream of the start codon.

Famous quotes containing the word history:
“In the history of the United States, there is no continuity at all. You can cut through it anywhere and nothing on this side of the cut has anything to do with anything on the other side.”
—Henry Brooks Adams (1838–1918)
“These anyway might think it was important
That human history should not be shortened.”
—Robert Frost (1874–1963)
“What you don’t understand is that it is possible to be an atheist, it is possible not to know if God exists or why He should, and yet to believe that man does not live in a state of nature but in history, and that history as we know it now began with Christ, it was founded by Him on the Gospels.”
—Boris Pasternak (1890–1960)
