[Detection of gamma-interferon mRNA in JEG-3 choriocarcinoma cell line by means of polymerase chain reaction].
1994
: To investigate the pathogenesis of choriocarcinoma the authors employed a newly developed gene amplification method by reverse polymerase chain reaction for the detection of gamma-interferon messenger RNA in JEG-3 choriocarcinoma cell line. Polymerase chain reaction products were analysed by agarose gel electrophoresis. Using 1 Kb DNA ladder as a marker, 84 base-pair fragment was selectively amplified correlating with published gamma-interferon gene fragment length. Because cDNA contains a virtually complete copy of the mRNA this method provides an evidence for the expression of gamma-interferon gene in JEG-3 choriocarcinoma cell line. Based on these results a potential autocrine mechanism may be present in JEG-3 choriocarcinoma cell line.
