2. Carcinoma del Colonretto e Flogosi
Il carcinoma colorettale è una delle patologie tumorali maligne più diffuse nel mondo occidentale.
Come importanza nell’uomo è secondo solo al tumore al polmone, mentre nella donna viene dopo
il tumore al polmone e alla mammella.
La loro causa precisa è sconosciuta, ma hanno importanza, tra gli altri fattori, la dieta, una
predisposizione ereditaria, e alcune patologie definite pre-neoplastiche, come le malattie
infiammatorie croniche dell’intestino (morbo di Crohn e retto-colite ulcerosa) e la poliposi
intestinale.
Il carcinoma colorettale mostra un classico esempio di patogenesi multifattoriale.
Accanto a modificazioni genetiche, è necessario che il tumore acquisisca particolari caratteristiche
fenotipiche che gli consentano di svilupparsi, eludere il sistema immunitario, invadere i tessuti
circostanti, creare nuovi vasi e diffondere a distanza attraverso le vie ematiche e linfatiche.

3. Chaperonine e Genotossicità
Numerosi studi hanno dimostrato che tra le
caratteristiche fenotipiche assunte dalle
cellule tumorali del colon vi è l’aumento
intracellulare delle “Heat Shock Proteins –
HSPs”.

Abstract
Strains of bifidobacteria have many health-promotion effects. Whole cells or cytoplasm extracts of Bifidobacterium bifidum
BGN4, isolated from human feces, inhibited the growth of several cancer cell lines. The polysaccharide fraction (BB-pol) extracted
from B. bifidum BGN4 had a novel composition, comprising chiroinositol, rhamnose, glucose, galactose, and ribose. Three human
colon cancer cell lines were treated with BB-pol: HT-29, HCT-116, and Caco-2. Trypan blue exclusion assay and BrdU incorpora-
tion assay showed that BB-pol inhibited the growth of HT-29 and HCT-116 cells but did not inhibit the growth of Caco-2 cells.
