These results do not contradict the hypothesis that ETBF strains can be proinflammatory and oncogenic bacteria, but additional studies are needed to understand the possible role of ETBF in colorectal carcinogenesis .
In summary, our results show that dysregulation of polyamine metabolism in all stages of CRC can be associated with chronic inflammation mediators rather than with the infection caused by ETBF.
The samples with high rates of ETBF colonization tend to have higher expression of SMOX, especially in normal tissue (compared to the other norms).
For Australian fisheries, onboard scientific observers from the Australian Fisheries Management Authority have recorded size composition data for wahoo in the ETBF since 2002.
the 2 commercial fisheries, ETBF and New Caledonia, and the EC Rec) were used to construct length-converted catch curves according to the methods of Pauly (1983, 1984a, 1984b).
t] = the selectivity and fishing mortality at age for the ETBF, EC Rec, and New Caledonia (New Cal) fisheries, respectively.
Observer data from the ETBF were investigated to identify the life status of wahoo upon hauling--ranging from dead and in rigor mortis to alive and vigorous.
In the IBD group, all the patients positive for ETBF
had active disease, which suggests an association with disease activation or flare-up.
They observed that mice infected with ETBF developed diarrhoea that resolved quickly, but within a week, the animals developed inflammation and small tumours in the colon.
Drew Pardoll, an immunologist and cancer researcher at Johns Hopkins, speculates that in humans, infection with ETBF "produces a low-level inflammation that persists for a long time.
If what we are seeing in mice holds true in humans, the chronic inflammation damages genetic material in the colon cells, allowing them to grow uncontrollably and develop into tumors earlier and more progressively than if they were not infected with ETBF," Pardoll says.
Sears and Pardoll believe that ETBF may collude with other types of normal bacteria in the gut to promote cancer.
