Popis: We searched for chromosome 3p homo- and hemizygous losses in 23 lung cancer cell lines, 53 renal cell and 22 breast carcinoma biopsies using 31 microsatellite markers located in frequently deleted 3p regions. In addition, two sequence-tagged site markers (NLJ-003 and NL3-001) located in the Alu-PCR clone 20 region (AP20) and lung cancer (LUCA) regions, respectively, were used for quantitative real-time PCR (QPCR). We found frequent (10-18%) homozygous deletions (HDs) in both 3p21.3 regions in the biopsies and lung cancer cell lines. In addition, we discovered that amplification of 3p is a very common (15-42.5%) event in these cancers and probably in other epithelial malignancies. QPCR showed that aberrations of either NLJ-003 or NL3-001 were detected in more than 90% of all studied cases. HDs were frequently detected simultaneously both in NLJ-003 or NL3-001 loci in the same tumour (P
