Vitamina A este responsabil\u0103 de o bun\u0103 acuitate vizual\u0103, un sistem imunitar <\/a>care func\u021bioneaz\u0103 \u00een mod corespunz\u0103tor \u015fi, mai nou, de suprimarea cancerului colorectal<\/a>.
\nUn nou studiu de la Stanford University School of Medicine arat\u0103 o leg\u0103tur\u0103 \u00eentre acidul retinoic, un compus derivat din vitamina A, \u015fi inhibarea cancerului colorectal la \u015foareci \u015fi la om. \u201eIntestinul este \u00een mod constant bombardat de organisme str\u0103ine. Exist\u0103 o leg\u0103tur\u0103 clar\u0103 \u00eentre boala inflamatorie a intestinului la om, ca de exemplu colita ulceroas\u0103, \u0219i eventuala dezvoltare a cancerului colorectal. Acidul retinoic e cunoscut de ani de zile ca fiind implicat \u00een suprimarea inflama\u0163iei \u00een intestin. Am conectat aceste lucruri \u015fi am \u00eencercat s\u0103 afl\u0103m dac\u0103 \u0219i cum nivelurile de acid retinoic afecteaz\u0103 \u00een mod direct dezvoltarea cancerului<\/em>\u201d, spune dr. Edgar Engleman, profesor de patologie \u015fi medicin\u0103.<\/p>\n

Acidul retinoic este esen\u021bial pentru mai multe procese de cre\u0219tere \u0219i dezvoltare \u0219i a f\u0103cut obiectul a numeroase studii \u0219tiin\u021bifice recente. Cercet\u0103torii au fost con\u0219tien\u021bi c\u0103 rela\u021bia acestui acid cu inflama\u021bia \u0219i microorganismele intestinale legate de imunitate este dificil de studiat, deoarece se degradeaz\u0103 rapid atunci c\u00eend este expus la lumin\u0103.<\/p>\n

\u201eA devenit foarte clar prin mai multe studii c\u0103 inflama\u0163ia cronic\u0103 este un factor foarte important de risc pentru mai multe tipuri de cancer. Acum, c\u0103 am demonstrat un rol al deficitului de acid retinoic \u00een cancerul colorectal, vrem s\u0103 identific\u0103m microorganismele specifice care ini\u021biaz\u0103 aceste schimb\u0103ri la om. \u00cen cele din urm\u0103, sper\u0103m s\u0103 afl\u0103m dac\u0103 descoperirile noastre ar putea fi utile pentru prevenirea sau tratamentul cancerului <\/a>colorectal<\/em>\u201d, a spus Engleman.<\/p>\n
