W przestrzeni kosmicznej astronautom towarzyszy\u0142o wiele r\u00f3\u017cnych stworze\u0144. Podobnie jak ludzie, wi\u0119kszo\u015bci z nich trudno jest przystosowa\u0107 si\u0119 do stanu niewa\u017cko\u015bci. Wyj\u0105tkiem jest malutki robak znany jako C. elegans, kt\u00f3ry wydaje si\u0119 radzi\u0107 sobie lepiej na orbicie ni\u017c na Ziemi.<\/p>\n<\/div>\n

Kiedy astronauta ESA Andr\u00e9 Kuipers po raz pierwszy uda\u0142 si\u0119 na Mi\u0119dzynarodow\u0105 Stacj\u0119 Kosmiczn\u0105 (ISS) w 2004 roku, do zabrania ze sob\u0105 wybrano C. elegans. Te mikroskopijne robaki wybrano, poniewa\u017c by\u0142y pierwsz\u0105 z\u0142o\u017con\u0105 form\u0105 \u017cycia, kt\u00f3rej wszystkie geny (elementy budulcowe kom\u00f3rek cia\u0142a) zosta\u0142y zsekwencjonowane.<\/p>\n

Nast\u0119pnie naukowcy odkryli, \u017ce siedem gen\u00f3w tych robak\u00f3w wykazywa\u0142o mniejsz\u0105 aktywno\u015b\u0107 w przestrzeni kosmicznej. Co zaskakuj\u0105ce, robaki wydawa\u0142y si\u0119 funkcjonowa\u0107 lepiej bez nich. Wyniki sugerowa\u0142y, \u017ce ich mi\u0119\u015bnie dostosowywa\u0142y si\u0119 do warunk\u00f3w panuj\u0105cych w przestrzeni kosmicznej. Czy loty kosmiczne mog\u0142yby spowolni\u0107 proces starzenia si\u0119 mi\u0119\u015bni?<\/p>\n

Eksperymenty laboratoryjne potwierdzi\u0142y, \u017ce inne robaki hodowane bez tych siedmiu gen\u00f3w r\u00f3wnie\u017c \u017cy\u0142y d\u0142u\u017cej i cieszy\u0142y si\u0119 lepszym zdrowiem. Poniewa\u017c ludzie maj\u0105 oko\u0142o 55% gen\u00f3w wsp\u00f3lnych z C. elegans, kolejnym krokiem by\u0142o ustalenie, jak mi\u0119\u015bnie cz\u0142owieka reaguj\u0105 na lot kosmiczny.<\/p>\n

Podczas swojej drugiej misji na Mi\u0119dzynarodowej Stacji Kosmicznej (ISS), kt\u00f3ra zako\u0144czy\u0142a si\u0119 1 lipca, Andr\u00e9 zabra\u0142 ze sob\u0105 kolejne robaki do dalszych bada\u0144. Tym razem jednak obiektem bada\u0144 by\u0142 r\u00f3wnie\u017c sam astronauta. Przed rozpocz\u0119ciem misji pobrano z jednej z jego n\u00f3g niewielki fragment mi\u0119\u015bnia i zachowano go do analizy. Naukowcy z niecierpliwo\u015bci\u0105 czekaj\u0105 teraz na por\u00f3wnanie tej pr\u00f3bki z mi\u0119\u015bniami, kt\u00f3re sp\u0119dzi\u0142y sze\u015b\u0107 miesi\u0119cy w stanie niewa\u017cko\u015bci. Jednak w przeciwie\u0144stwie do robak\u00f3w, Andr\u00e9 ma kilka tygodni na regeneracj\u0119 po m\u0119cz\u0105cej podr\u00f3\u017cy, zanim jego mi\u0119\u015bnie trafi\u0105 pod mikroskop.<\/p>","protected":false},"excerpt":{"rendered":"
