Prehistoric Gene Reawakened To Battle HIV

Linuss points out research published in PLoS Biology that demonstrates the reawakening of latent human cells' ability to manufacture an HIV defense. A group of scientists led by Nitya Venkataraman began with the knowledge that Old World monkeys have a built-in immunity to HIV: a protein that can prevent HIV from entering cell walls and starting an infection. They examined the human genome for any evidence of a latent gene that could manufacture such a protein, and found the capability in a stretch of what has been dismissively termed "junk DNA." "In this work, we reveal that, upon correction of the premature termination codon in theta-defensin pseudogenes, human myeloid cells produce cyclic, antiviral peptides (which we have termed 'retrocyclins'), indicating that the cells retain the intact machinery to make cyclic peptides. Furthermore, we exploited the ability of aminoglycoside antibiotics to read-through the premature termination codon within retrocyclin transcripts to produce functional peptides that are active against HIV-1. Given that the endogenous production of retrocyclins could also be restored in human cervicovaginal tissues, we propose that aminoglycoside-based topical microbicides might be useful in preventing sexual transmission of HIV-1."

Well, if it works, and if recompiling with different options might break it... Just ship it! Too bad God remembered to strip the symbols at that point, because if he had left them in, we wouldn't have this silly evolution vs. intelligent design argument at all, and wouldn't have to figure out everything about our DNA by ourselves.

    Unfortunately no. By using the 'pwned' in reference to a potentially major scientific breakthrough you've actually made AIDS mutate to become airborne and highly contagious.

    It's called the 'Nantucket Principle'. Where using idiotic phrases in reference to intelligent work causes the work to be destroyed.

    Another case of this principle at work was when the Wright brothers tried their first airplane prototype. Just before they were going to do their first test flight Orville said something to the effect of 'We are going to codfloddle this strumpet!' which caused Bernoulli's principle to completely change, setting flight back many years.
