“…Gorlova used quantitative reverse transcription (RT-PCR) to detect the expression of PinX1 in 73 cases of GC and used microsatellite marker d8s277 to further study the loss of heterozygosity (LOH) in 45 cases (11,12). It was found that in 73 cases of GC, the expression of PinX1 decreased in 50 cases (68.5%) (tumor and normal control < 0.5%) (13)(14)(15). In addition, LOH of the PinX1 gene was detected in 15 (33.3%) of 45 GC cases, which was significantly related to the decreased expression of the PinX1 gene (P = 0.031) (16).…”
