Cercet\u0103torii de la Universitatea Na\u021bional\u0103 din Singapore au folosit bacterii concepute genetic \u00eentr-un probiotic (mediu bacterian, propice bunei func\u021bionari a colonului, flor\u0103 bacterian\u0103 fiziologic\u0103) care se leag\u0103 de suprafa\u021ba celulelor cancerului colorectal \u0219i secret\u0103 o enzim\u0103 care transform\u0103 o substan\u021b\u0103 g\u0103sit\u0103 \u00een legumele cruciferoase, cum ar fi broccoli, \u00eentr-un puternic agent anticancerigen. Elementul principal al acestui sistem de \u021bintire a cancerului este o form\u0103 de modificare genetic\u0103 a lui E. coli Nissle, o specie bacterian\u0103 inofensiv\u0103 g\u0103sit\u0103 \u00een intestin. Cercetarea urm\u0103rea s\u0103 distrug\u0103 celulele canceroase din intestin, permi\u021b\u00e2ndu-le s\u0103 preia acest agent anticanceros. Deoarece celulele normale nu pot face aceast\u0103 conversie \u0219i nu sunt afectate de toxin\u0103, sistemul este de a\u0219teptat s\u0103 vizeze numai celulele cancerului colorectal.<\/p>\n

Testarea a demonstrate c\u0103 mai mult de 95% din celulele cancerului colorectal testate au fost ucise de amestecul de probiotice modificate genetic cu un extract de broccoli sau ap\u0103 care con\u021bine substan\u021ba dietetic\u0103. \u00cens\u0103, acest amestec nu a avut niciun impact asupra altor tipuri de celule canceroase, cum ar fi cele ale cancerului de s\u00e2n sau de stomac.<\/p>\n

Potrivit studiului, combina\u021bia de probiotic-vegetal\u0103 a sc\u0103zut cu 75% \u00a0num\u0103rul tumorilor la \u0219oarecii cu cancer colorectal. De asemenea, \u00een compara\u021bie cu \u0219oarecii de control, c\u0103rora nu le-a fost furnizat amestecul, tumorile \u0219oarecilor trata\u021bi au fost de trei ori mai mici.<\/p>\n

Echipa de cercet\u0103tori acrediteaz\u0103 c\u0103 aceste probiotice ar putea servi \u00een viitor \u00een scop dublu: la prevenirea \u0219i cur\u0103\u021barea celulelor canceroase reziduale dup\u0103 opera\u021bie sau la chimioradioterapie. Se sper\u0103 c\u0103 pacien\u021bii cu cancer colorectal ar putea lua probioticele ca supliment alimentar \u00eempreun\u0103 cu consumul de broccoli pentru a preveni cancerul colorectal sau pentru a reduce ratele de recidiv\u0103 dup\u0103 interven\u021bia chirurgical\u0103.<\/p>\n

Cercet\u0103torii consider\u0103 c\u0103 un aspect important al descoperirii este acela c\u0103 oamenii \u00ee\u0219i pot transforma dieta normal\u0103 \u00eentr-un regim terapeutic durabil \u0219i ieftin. De asemenea, se sper\u0103 ca aceast\u0103 strategie s\u0103 fie un complement util terapiilor curente de cancer.<\/p>\n

Cancerul colorectal este al treilea cel mai frecvent cancer la nivel mondial, iar inciden\u021ba acestuia se preconizeaz\u0103 c\u0103 va cre\u0219te \u00een urm\u0103torii c\u00e2\u021biva ani. Studiul, care a fost coordonat de dr. Chun-Loong Ho, a fost recent publicat \u00een revista Nature Biomedical Engineering.<\/p>\n","protected":false},"excerpt":{"rendered":"
