Abstract
The human high mobility group (HMG) protein (HMGI-C) belongs to the HMG family of
architectural transcription factors which are expressed only during embryonic development,
and not in normal adult tissues. Considerable interest has recently been shown in
HMGI-C and its expression in a variety of neoplastic tissues, whereas no expression could
be found in normal tissue adjacent to the tumour. So far, no data is available on
the expression of HMGI-C in the peripheral blood of patients with solid tumours. In this study we analysed
the expression of HMGI-C in peripheral blood samples of 61 patients with breast cancer and 35 healthy donors
using a haemi-nested reverse transcriptase–polymerase chain reaction (RT-PCR) technique.
No HMGI-C could be detected in any of the healthy donors' samples. In the three prognostic
groups according to the Nottingham Prognostic Score, the proportion of patients expressing
HMGI-C differed significantly (P=0.001). The worse the prognosis was, the more patients expressed HMGI-C. This is the first report on the expression of HMGI-C in the peripheral blood of patients with breast cancer and our data suggest that
this expression is correlated with a poor prognosis.
