Expression levels of the GEFs studied related to NPI status of the tumours


Guanine Nucleotide Exchange Factors

NPI status
TRIO
VAV1
TIAM-1

(NPI < 3.4)
109 ± 44
0.45 ± 0.22
1957 ± 1466

(NPI 3.4–5.4)
234 ± 113
1.18 ± 1.06
506 ± 205

(NPI > 5.4)
315 ± 176
0.45 ± 0.41
298 ± 123

NPI = Nottingham Prognostic Index.

Levels of Trio showed a sequential increase with increased NPI status with a significant increase from NPI1 to NPI2 (p = 0.04). Expression of Vav1 showed no definitive pattern while TIAM-1 expression showed a sequential decrease with an increase in NPI status.
