OBJECTIVE: To investigate the expression of leukemia inhibitory factor (LIF) in the decidua of normal early pregnancy, threatened abortion and inevitable abortion.
METHOD: We examined LIF gene expression in the above-mentioned decidua by a quantitative reverse transcription-polymerase chain reaction (RT-PCR) method, and also examined the serum pregesterone, human chorionic gonadotrapin (hCG) by radioimmunoassay in all cases.
RESULTS: (1) Serum levels of pregesterone and hCG are: (91.5 +/- 27.2) nmol/L, (69.9 +/- 14.9) kU/L in normal early pregnancy; (88.4 +/- 24.7) nmol/L, (57.6 +/- 11.2) kU/L in threatened abortion respectively. There was no difference in the levels of pregesterone and hCG between the two groups (P > 0.05). While serum pregesterone, hCG levels in inevitable group were (33.1 +/- 19.6) nmol/L, (10.3 +/- 3.2) kU/L respectively. Compared with normal early pregnancy and threatened abortion group, the levels of serum pregesterone and hCG reduced significantly (P < 0.05). (2) The expression of LIF in three groups: There was no statistically significant difference in the levels of LIF expression between the normal early pregnancy group (2.10 +/- 0.32) and threatened abortion (1.92 +/- 0.20) groups, while the levels of LIF expression in inevitable abortion group (0.7 +/- 0.06) was lower than those in normal early pregnancy group and threatened abortion group (P < 0.05, respectively).
CONCLUSION: The reduction of LIFmRNA expression in the decidua of early pregnancy may decrease the serum pregesterone and hCG levels and cause inevitable abortion.
