    Abstract:
    To investigate if there are microsatellite loci in the long arm of chromosome 6 that have close relationship with non-small cell lung cancer, Multiple PCR approach was used to analyze the 36 loci in the long arm of chromosome 6. The PCR products were analyzed in PAGE and then the electrophoresis maps were analyzed with Genescan and Genotyper. There is different LOH frequency in different loci. The total frequency of LOH in 41 lung cancers was 78%(32/41), with the highest frequency of LOH was detected on the locus D6S302(75%). There are 14 loci which have LOH frequency more than 20% and the loci are mainly located in 2 regions: 6q16.3-q21 [6 loci D6S458 (21.43%), D6S1694 (26.92%), D6S1717 (35.71%), D6S1565 (40%), D6S302 (75%), D6S1706 (36.36%) and 6q26-q27 (5 loci D6S1550 (38.46%), D6S264 (20%), D6S1585 (25%), D6S446 (33.33%), D6S281 (30.77%)], There may be tumor suppressor genes located in the two regions, which have a close relationship with non-small cell lung cancer.
