Coffee's Caffeine-Producing Gene Isolated

matthewd writes: "Hackers everywhere should be interested in this AP article about the gene that is the key to caffeine production in coffee being isolated. (I also found another article that's almost a year old that is very similar.) Of course hackers wouldn't even be interested in coffee sans caffeine. However, once the genetic basis for caffeine production is isolated, the obvious application besides removing it from coffee is to insert this genetic codes into the human body, so that your body can produce caffeine on it's own (perhaps even regulated by the body's circadian rhythm). Everyone ready to hack their bodies?"

There is a broader implication though: It's known that many drugs come from or are discovered in naturally occuring plants and then synthesized. If the genetic basis for these types drugs can be discovered and replicated, you could turn the human body into it's own pharmacy. Maybe synthesizing salicin internally could be as effective as taking aspirin? (and less irritating for your stomach) Or maybe if the fundamental genetic operations that synthesize chemicals/proteins is discovered (the microcode of cells?) you could even synthesize chemicals that don't occur naturally. Perhaps in the future a "pharmaceutical organ" will be hacked into the human body specifically for this purpose.

Of course there's the other side to this, where people will want to synthesize certain chemcials in opiates or marijuana ... Fun to speculate about, at least!"

      One recent theory of sleep is that the bloodstream can't carry enough energy to the brain to sustain it. While awake, brains use bloodstream-delivered energy and stored energy. Sleep is needed to recharge the stored energy -- apparently it's stored in glial cells.

      It will be quite a challenge to alter the physiology and chemistry enough to solve that problem.

      This theory arose out of the simple observation that not having to sleep would be a tremendous evolutionary advantage -- so why are there not more animals that do not sleep?

      You are only partially wrong. Most neurologically active drugs do indeed bind to receptors of endogenous chemicals that they "impersonate," and have a direct effect on the levels and/or action of that transmitter. However, they seldom function as simple analogues -- a single drug can bind to many types of receptors, and can directly increase or decrease the levels of many endogenous compounds.

      Caffeine, though, is sort of a special case. Unlike the "classic" stimulants such as amphetamine, cocaine, or ephedra, it does not have a dramatic effect on dopamine or epinephrine (adrenaline) levels in the CNS. Instead, it increases calcium ion transfer in the nervous system, effectively lowering the threshold for a signal to get through. Every nerve cell in your body simply becomes more active, but continues carrying more or less the same data as before.

      Think of it this way: Most drugs work like new components in a computer, such as a processor or drive. Just like a processor upgrade, or new sound card, they fundamentally alter the way it operates, and may or may not be totally compatible with the rest of the system. Caffeine, on the other hand, is much more like overclocking the system bus. None of the data being transferred changes, but it moves at a faster rate from place to place.

      Unfortunately, just like OC'ing a machine, caffeinating your body doesn't do wonders for its reliability. Sometimes those nerve cells really don't take well to being pushed harder, and the signals start getting noisy while passing from place to place.

It's "enjoyable" effects are largely conditioned response, as people learn to expect and appreciate the perceived increase in their mental and physical energy levels.

      Drinking coffee is "just doing drugs," albeit in a socially acceptable and ritualistic fashion. Many "hard" drug users have an equal amount of daily ritual to their usage, and probably gain similar psychological imprinting. If you want to make caffeine a more "natural" reward, then trigger its release only after certain phsyical criteria are met, just as endorphins are only released when the body has a reason for it.

      However, the body already has a similar response in its use of adrenaline (or epinephrine to you Europeans out there).

An example from daily life would be the popularity of spicy food: in reaction to the pepper/chilli/blowtorch, the brain releases some endorphins to lessen the painful sensation you get from ingesting spicy foods. We perceive this release of endorphins to be pleasurable, in much the same way that a junkie perceives his shot of Heroin to be pleasurable. This probably explains the popularity of Mexican/Indian/etc. food.

      If you eat a lot of these foods over a prolonged period of time, you begin to become tolerant to the levels of endorphin that are released after each meal. The level of spiciness ("mild", say) you started out with no longer serves to give you your kick. So you move on to "fairly hot" and eventually "blitzkrieg" in order to "keep up your habit".

    The possibilities are endless.
    Of course, whenever you use something like this you'll pay the price later (fatigue, twiches, withdrawl, migranes) - you never get something for nothing. But wouldn't it be great to have the choice?

  27. Major Misconceptions! by Hatta · · Score: 3

    There is not just *one* gene responsible for producing caffeine, or any biomolecule. They are all produced through pathways consisting of multiple enzymes, and some sort of complex regulatory system where the cell might produce another molecule that inhibits one or more of the enzymes, or it may just stop producing enzymes and the "assembly line" get's backed up.

    I like that analogy. Each enzyme is like a laborer on an assembly line. What they've found here is one gene that makes one enzyme. Disable that gene and the assembly line can't procede past a certain point. You cannot just stick that gene in another organism, and expect to have a caffeine factory!

    It is however done, that bacteria are altered to produce chemicals, however in these cases, we don't care about gene regulation. They can spew out all the insulin they can!

    A side thought about what they're proposing here. Many of these pathways are down-regulated by end product. It's feedback inhibition, like a thermostat. But I see a possible problem here. Say you have a 2 step process going from compound A through intermediate B and finishing at product C

    A--->B--->C
    ^ |
    --------

    (please excuse the awful ascii art)

    product C, in high concentrations stops production of intermediate B, but if the step from B to C is stopped, say by removing the gene for the necessary enzyme, there's nothing to stop the production of B, you'll end up with tons of B which may taste bad, be unhealthy, something, and no A, which may be required for something else.

    B BB B
    B B B
    A--->B-X->C
    BBB B BB
    BB BB B B

    Just some thoughts

  28. grafting Illicit-substance genes by Captain+Pillbug · · Score: 2

    Of course there's the other side to this, where people will want to synthesize certain chemcials in opiates or marijuana ... Fun to speculate about, at least!

    No kidding. Some day, it'll be feasible for someone to graft a THC gene into his own body so that he basically pisses marijuana. It's already silly for governments to wage war on a naturally occurring feral plant, but how much sillier will it be when it's no longer an external plant but instead one's own body? What'll happen when some enterprising and politically conscious person hacks his own genetic code so as to shit pellets with DeCSS engraved on them? Will his own offspring be contraband?

    Though it'd be nice for when I couldn't find a coke. Just need to find a way to make the process slow down or pick up as needed. Might have to install a dial. Only prob is if someone turns it up too fast by accident you might get seizures or something. It'd create a whole new series of medical problems (overdosing during pregnancy for instance)

    Alright, that said, I think this could really improve the state of decaf coffee. Currently, the way they make it is to (essentially) brew the beans once with an icky batch of chemicals that supposedly sucks out the caffiene, but leaves the flavor it. Yeah, right.

    But, if they could just disable the caf-gene so the caffeine was never produced at all, then no intermediate step, and therefore better decaf! This would be useful for those times when you're trying to "cut down" because you're drinking 15 cups a day... switch a few to genetically engineered decaf, and you get all the yummy fun without all the speed.

  33. We're already hacking our bodies by bugzilla · · Score: 2

    Yes, it's true. We, as a race, have been hacking our bodies since we've had them. Many of you probably have similar daily hacks that you perfom, as do I, to tune and enhance the operation of our bodies.

    We eat and drink caffeinated foods and beverages in an effort to enhance alertness and to defeat our own circadian rythms. We wear eyeglasses in order to improve on factory standard equipment and to protect these vital tissues from damaging rays whilst out and about in the Big Blue Room. Some of us even submit these oh-so-tender pieces of flesh to the awesome might of a laser for input correction and re-alignment. We wear an assortment of braces and supports to relieve muscle pain and fatigue, use caustic chemicals to enhance our physical appearance, and braces on our teeth to guide the growth and placement of what would otherwise be non-parallel placed mastication devices. And then there's the whole Pandora's box of plastic surgery...

    See what I mean? I know, I know, you're saying "but I want to tune my endorphin output using a heads-up display in my peripheral vision!" Hell, so do I. That's just hacking at the next level. We have been hacking our bodies for so long, most of us using the equivalent of rootkits, that we tend to forget that we are doing it. When articles like this talk about getting ready to hack your body they do so by keeping all of the daily hacks we all participate in below the base-line of what is currently possible.

    Humans will create something not because it is needed but instead because it is possible. Once these things are made and used widely then they are, in effect, just another part of the human body, or more accurately a module which can be elected for use or not. We are already hacking our bodies, just not at the desired level. This is good. For what good would a hack be that had no room for improvement at a later date? Boring, I say. So bring on the cybernetic implants, the gene therapy, the bio-computers peppered about my person and the nanites on the rampage within. Bring it on, and let the hacking continue!

    Hacking a body to make it perform better instead of optimally is a bad thing.
    You say the human body could syntetize caffeine itself but you could be much more friendly with your body by sleeping some time, even like Dali's flash sleep.
    Look at the "Tour de France": Most of its performers are taking loads of alien drugs and though they finish in the Tour's few first, finish completely stoned out of the competition.
    It is because of the current level of competition and because of the mediatic heavy fire that people feel likle beating more and more records not even because of the original sane thing that people call challenge or self-improvement but because they need recognition that people won't usually offer them if they just happen to be only cool.
    So, yes, of course, you could make your body synthetize coffee, drugs or even adamantium but it will still secrete shit on a dayly basis and you'll still have to do with this.

    Seen from Denmark the coffein obsession is an American phenomen. Everybody here drink some disgustingly strong tasting coffee in absurd quantities, and the idea of decaffenated anything (coffee, tea, cola) is meet with puzzlement. Why would anyone want that? The point being, most people here are coffein junkies, and don't know it or recognize it as a problem.

    Nerds are probably *less* coffein-addicted than the average population, simply because cola contains much less coffein than coffee.

  36. Body ALREADY produces caffeine-like substance.. by Sleepy · · Score: 2

    The reason that drugs "work" in the human body is because the the molecular structure of the drug fits a natural "keyhole" somewhere.

    Basically the body has natural recepticle's for natural hormones... drugs fit those keyholes - often imperfectly. Your body thinks caffeine is adrenaline and acts (mostly) accordingly. Your body naturally produces adrenaline, and it works a hell of a lot better than caffeine.

    I like caffeine because I can get a rush while still being a computer slug, but I understand the difference. :)

    I suspect if we could turn on and off adrenaline like we drink coffee, the body would develop some resistance...
