PMID- 9071573 OWN - NLM STAT- MEDLINE DCOM- 19970612 LR - 20061115 IS - 1045-2257 (Print) IS - 1045-2257 (Linking) VI - 18 IP - 3 DP - 1997 Mar TI - A 3p21.3 region is preferentially eliminated from human chromosome 3/mouse microcell hybrids during tumor growth in SCID mice. PG - 200-11 AB - We have previously shown that four markers spanning the 3p24-p21.3 region, THRB, AP20R, D3S1029, and D3S32, were regularly eliminated from three human chromosome 3 (chr3)/mouse microcell hybrids (MCHs) during tumor growth in SCID mice. In an attempt to narrow down the eliminated region, we have studied 22 new SCID mouse tumors derived from 5 MCH lines carrying human chr3. They were analyzed by fluorescence in situ hybridization (FISH), Southern blotting, and polymerase chain reaction (PCR). MCHs that carried human chr1, chr8, chr13, and chr17 were examined as controls. We could identify a common eliminated region (CER) at 3p21.3, bordered distally by D3S1260 and proximally by D3S643/D3F15S2. Eight of 53 chr3-specific PCR markers, AP20R, D3S966, D3S3559, D3S1029, WI-7947, D3S2354, AFMb362wb9, and D3S32. were localized within the CER. This finding is consistent with the notion that a tumor suppressor gene may be located in this area, as suggested by frequent loss of heterozygosity (LOH) within this region observed in several types of solid tumors.
