Detailed product of the expected length was seen in all the SCLC-derived cell pulsed field analysis, including double digests with the enzymes used lines examined. A primer set for GNAI2, however, failed to detect any to construct the map (see Fig. lc), indicated that the 360-kilobase Not! PCR product from GLC2O.

Both probes detect the same As a first step in the analysis of the region homozygously deleted 650-kilobase Not! fragment and the same 350-kilobase M1uI X Not! from GLC2O, the CEPH YAC library was screened with DD1-specific and 350-kilobase Nru! X Not! fragments. This positions DD1 in an primers. Thirty individual yeast colonies, all originating from the already established long range map (16) at a distance of slightly less same DDJ-positive library address 181H1, contained YACs varying than 350 kilobases from UBE1L (see also Fig. 74, which we formerly in length from 60—340 kilobases (Fig. 3). FISH analysis with. the longest YAC proved that it was nonchimeric. By applying a vector SCLC ette-PCR protocol to four of these YACs, we could demonstrate that they had identical endclones. For 19 individual 181H1 YACS, we HP * constructed an M1uI,NruI, and Not! restriction map. A comparison of these maps with the pulsed-field map showed that the left endclone I (H1L) of all 181H1 YACS mapped at 80 kilobases from DD1 in the @@ UBE1L ilO-kilobase genomic Not! fragment, i.e., within the GLC2Odeletion. Indeed, amplification of GLC2O DNA with primers derived from H1L failed to produce a PCR product. The right endclone (H1R) mapped at 45 kilobases from the Nru!/Mlu! site between UBE1L and APEH. Thus, in control DNA, the endclones of 181H1 span a genomic region @ DD1 —.•q of about 475 kilobases, implying that even the longest (340-kilobase) YAC we obtained still carries a deletion of some 135 kilobases. In 8 of 15 YACS, the deletion included the DD1 homologous sequence. We subsequently screened the YAC library with primers specific for H1L, H1R, and UBE1L, respectively. This resulted in four more YACS. 407A1 1 (nonchimeric; 300 kilobases) is positive for H1R and @ ZnF1 6 ——.@-@ _ .. UBE1L but not for DD1. This YAC also overlaps with the loci APEH and D3F15S2, and thus extends away from DDJ. 191D3 (chimeric) is positive for H1R but not for UBE1L.

In the structural part of the gene, no mutations could be namely 407A11 and 181B3, isolated with the endclones of 181H1, detected. Tumor suppressor genes can, however, be distinguished in plus one at a larger distance, for which we used the nonchimeric YAC two classes (29). The so-called class ! tumor suppressor genes are 264C5, isolated with MYL3. By first hybridizing YACS 407A11 and those in which loss of function results from mutation or deletion of 264C5 to prometaphase chromosomes from blood lymphocytes, YAC DNA. UBE1L, therefore, cannot be a class I tumor suppressor gene. 407A1 1 containingAPEH and UBE1L turned out to map centromeric For class II tumor suppressor genes, loss of function is caused by a to 264C5, containing MYL3 (Fig. 4). From a subsequent interphase regulatory block of expression. Such genes are supposed to be regu FISH analysis of 407A1 1 and 181B3 in combination with 264C5 lated from a different locus. Also for UBEJL, there is still the (results not shown), the order of the YACS from telomere to centro possibility that its expression is under direct positive control of a class mere could be established as 264C5—407A11—181B3.This implies I gene, which would defme UBEJL as a class II tumor suppressor that the UBE1L locus flanks the homozygous deletion at the telomeric gene. One or more class I gene(s) are, however, most likely present in end, whereas the ZnFJ6 locus flanks the deletion at its centromeric the 3p2l region in view of the results of microcell-mediated chromo end.

The introduction of either the whole of on interphase nuclei from normal lymphocytes in combination with chromosome 3 (30) or only part of it (6, 31) into tumor cell lines the cosmid containing DDJ, we could confirm that DD1 mapped resulted in a reduction of tumorigenicity. This is readily explained by between UBE1L and ZnFJ6 (Fig. 4b). When the same analysis was the assumption that a class I tumor suppressor gene must have been carried out on GLC2O cells, no signal was caused by the DD1- containing cosmid in any of the interphase nuclei analyzed (Fig. 4c). introduced.

A HOMOZYGOUS 3p2l DELETION IN AN SCLC CELL LINE

gous deletions occurred on chromosomes 5, 8 and X/Y, respectively (34). The latter two were found repeatedly in a small number of cell lines. The X/Y deletion was also detected in a lymph node metastasis. Since it did not occur in the primary tumor, it cannot be a primary event. Instead, this kind of homozygous deletion may reflect an increased genomic instability during progression of lung cancer in vivo or in vitro. Homozygous deletions on chromosome 9 were detected in 4 of 26 non-SCLC-derived cell lines but not in 6 SCLC derived cell lines (35). This is in line with the relatively high fre quency of loss of heterozygosity of 9p in non-SCLC (36). The smallest region of overlap of these homozygous deletions on chro mosome 9 is between the MTAP gene and the IFN gene cluster in band p22. From this region, a gene has been isolated which shows mutations in a variety of tumors, including non-SCLC (37, 38). A large homozygous deletion at 3pl2—l3 has been described to occur in the SCLC cell line U2020 (14, 39). As this deletion is not in 3p2l, the most commonly deleted region in lung cancer, its significance is unclear. More recently, homozygous 3p2l deletions have been reported in lung cancer-derived cell lines (10, 11). A cosmid that was mapped to 3p2l.3 by in situ hybridization detected homozygous deletions in 5 of 36 lung cancer cell lines (10). Thirty-nine more cosmids from 3p2l.3—
