ERVs and Multiple Sclerosis, #3

ERVs and Multiple Sclerosis ERVs and Multiple Sclerosis, #2 Hmmm… This new paper on the association between ‘active’ ERVs and Multiple Sclerosis is a step back, and a step forward, at the same time: Expression of HERV-Fc1, a human endogenous retrovirus, is increased in patients with active Multiple Sclerosis. If you go back and read…

ERVs, epigenetics, and the alcoholic brain

Let me make this clear, for like the millionth time: You do not want transposable elements in your genome (DNA transposons, ERVs, LINEs, SINEs, etc) to be active and functional. You are happy, happy, happy that these elements are junk. Yes, occasionally a transposable element has been domesticated for the hosts purposes. Yes, I know,…

Arnie is a very happy dog (see photo in upper left). Its always a party when Arnie is around– He loves everyone and everything… … Everything, that is, except cats. It didnt used to be like that. Arnie used to like cats just fine. But then one day, when he was a puppy… Neighbor: Hey…

HERVs and disease and junk DNA

I love junk DNA. Well, thats an understatement– I mean I love is SO MUCH I created a blog dedicated to a particular form of junk DNA, endogenous retroviruses. I love how we can learn fantastic things about organisms (and their diseases) from, basically, dumpster-diving though millions and millions of years of mistakes and accidents…

HERVs and HIV-1

Quick recap of ERVs for new readers of ERV (or long-time readers who have forgotten!)– ERVs are retroviruses that accidentally infected an egg/sperm cell, and became a permanent part of that egg/sperms DNA. That egg/sperm then went on to successfully generate a viable embryo, and because that retrovirus was part of the egg/sperms DNA, it…

PERVs not a risk, manimals imminent

If there is one ERV I genuinely love talking about on ERV, its PERVs– Porcine Endogenous Retroviruses. And you all should care about them too– Pigs and their PERVs (or, lack of PERVs, or lack of infectious PERVs) might one day have a direct impact on you or your friends/family. Clinical trials involving tissue from…

Barnyard Week: BoERVs in Big Bos Taurus

Like BlagHag, I have a soft-spot for astrology. Not that I ever ‘believed’ in it, I have just always loved the stars and the moon and zodaic stuff is just fun. Via that, Ive also always had a soft-spot for cows. I am a Taurus, and I just think cows are pretty: I also love…

I LOVE talking about PERVs on ERV. PERVs. PERVs. EVEN MOAR PERVs. I LOVE PERVs! Well… PERVs as in Piggie Porcine Endogenous Retroviruses. Not pervs as in Catholic Priests and Teh Popes advisers. Thats a different story. Because the need for organs for transplants is so high, and because pigs are pretty great sources for…

So I got the idea to do this after stumbling across a bunch of viral/farmyard stories this week. I know its currently Tuesday, not Sunday, so, SURPRISE!!! BARNYARD WEEK! If you ERV readers are anything like me, you have spent countless nights tossing and turning in bed, unable to sleep, unable to stop pondering one…

SQUEEEEEEEEE!!!!!!!! The first sequenced carnivore genome shows complex host-endogenous retrovirus relationships. ONE note of dismay: They did not include a picture of the boxer they sequenced. WTF??? Substitute picture: see more dog and puppy pictures Fun quickies! Despite Arnies love of getting into the garbage, dogs have much less junk DNA via proviral ERVs than…
