The first major finding of this experiment
verifies that KM110r is able to target and selectively destroy U2OS cells
and is not toxic to hFOB cells over the range of temperatures 34°C, 37°C
and 39°C where hFOB cells are differentiating, which supports the initial
hypothesis. At 34°C and 37°C,
KM110r successfully eradicated all of the cancerous U2OS cells within the
experimentation period.
However, KM110r did not effectively destroy all cancerous cells at
39°C incubation, which was an unexpected finding. Furthermore at 37°C the
cancerous cells were completely eradicated at time periods 3 and 2 (for
trials #1 and #2 respectively), notably earlier than at 34°C
incubation. The second major finding is that the results
did not support identification of a specific point during in vitro cell differentiation that
the hFOB cells were infected by KM110r, rejecting the hypothesis that
under 39°C differentiation hFOB cells would become permissive to KM110r.
hFOB cells were not permissive to KM110r at any temperature condition.
Therefore the results suggest that KM110r is specific for changes leading
to tumorigenesis and not to changes leading to normal
differentiation.
The hFOB cells, at each of the three incubation
temperatures, grew at the same rate regardless of status of infection.
There was no significant difference between hFOB infected and uninfected
at each temperature condition. Significant changes in the growth curves of
U2OS infected cells at all temperatures were documented. These variations
were proven to be statistically different. The information generated by this novel
experimentation supports that KM110r is selectively oncolytic and is an
effective and safe oncolytic virus therapy under normal conditions of cell
growth and
differentiation. |
