Abstract
Metastasis is the dominant cause of patient death in small-cell lung cancer (SCLC), and a better understanding of the molecular mechanisms underlying SCLC metastasis may potentially improve clinical treatment. Through genome-scale screening for key regulators of mouse Rb1-/- Trp53-/- SCLC metastasis using the pooled CRISPR/Cas9 library, we identified Cullin5 (CUL5) and suppressor of cytokine signaling 3 (SOCS3), two components of the Cullin-RING E3 ubiquitin ligase complex, as top candidates. Mechanistically, the deficiency of CUL5 or SOCS3 disrupted the functional formation of the E3 ligase complex and prevented the degradation of integrin β1, which stabilized integrin β1 and activated downstream focal adhesion kinase/SRC (FAK/SRC) signaling and eventually drove SCLC metastasis. Low expression levels of CUL5 and SOCS3 were significantly associated with high integrin β1 levels and poor prognosis in a large cohort of 128 clinical patients with SCLC. Moreover, the CUL5-deficient SCLCs were vulnerable to the treatment of the FDA-approved SRC inhibitor dasatinib. Collectively, this work identifies the essential role of CUL5- and SOCS3-mediated integrin β1 turnover in controlling SCLC metastasis, which might have therapeutic implications.

Abstract
The morphology, karyotype, in vitro growth properties, and expression of tyrosine kinase receptors and proto-oncogenes are reported for a newly established large cell undifferentiated lung carcinoma cell line (RVH-6849). The results were analyzed concomitantly with those for two well-established cell lines from an adenocarcinoma of the lung (A549) and a squamous cell carcinoma (A431). All three cell lines demonstrated common ultrastructural features of epithelial cells, but only RVH-6849 had frequent aggregates of centrioles and annulate lamellae (AL) and was polyploid, having five to seven copies of chromosome 7 by karyotype analysis. All three cell lines expressed transforming growth factor alpha (TGF-alpha), epidermal growth factor receptor (EGFR), c-erb B-2, and c-met genes. RVH-6849 cells, however, expressed the most messenger RNA (mRNA) for TGF-alpha, c-erb B-2, and c-met. Only EGFR mRNA was expressed more in the other two cell lines, especially in A431 cells. AL represent an exaggerated form of the nuclear membrane-pore complex that is found in actively proliferating cells such as germ and some neoplastic cells. AL are suspected to be involved in the deposition or processing of mRNA: The enhanced coexpression of AL and mRNAs of three tyrosine kinase-containing receptors in RVH-6849 cells may represent such a relationship.

Abstract
In the United States, the 20th century witnessed the emergence of a lung cancer epidemic that peaked and began to decline by the century's end, a decline that continues today. However, lung cancer continues to be an unabating pandemic. In research carried out over the last half of the 20th century, many factors were causally associated with lung cancer and studies were implemented to identify determinants of susceptibility to these factors. Cigarette smoking was identified as the single most predominant cause of the lung cancer epidemic, but other causes were found, including workplace agents (eg, asbestos, arsenic, chromium, nickel, and radon) and other environmental factors (passive smoking, indoor radon, and air pollution). Contemporary epidemiologic research on lung cancer now focuses on a new set of issues, primarily related to susceptibility to the well-identified causal factors, particularly smoking, and on the consequences of changes in tobacco products for risks to smokers. Diet and the possibility of reducing risk through chemoprevention remain a focus of research emphasis through experimental and observational approaches. Questions have also been raised about possible differences in susceptibility to lung cancer by sex and race. Population patterns in smoking prevalence will continue to be the most powerful predictor of the future occurrence of lung cancer. Evaluation of recent US patterns in smoking prevalence indicates that for the next approximately 10 to 15 years, lung cancer rates will decrease, but will then level off starting in approximately 2030. Unless further reductions in the prevalence of cigarette smoking are achieved over the next decade, lung cancer will remain as an all too common, but avoidable, disease.

Abstract
Our understanding of lung cancer biology has rapidly expanded in recent years. Lung cancer, unlike most human cancers, can be traced to an environmental risk factor in the majority of cases, and this fact is reflected in the vast number of genetic alterations discovered in lung tumors whose pathogenesis is believed to be mediated by carcinogen exposure. The discovery of these alterations has led to a greater understanding of tumor development. The dramatic progress in the understanding of the genetic and molecular basis of oncogenesis and the induction of immunity has led to a rejuvenation of efforts to apply this new knowledge to this common and refractory disease. Further, the resurgent interest in cancer immunology and tumor-host interactions holds promise for the development of new approaches to treatment based on harvesting the immune systems ability to recognize these alterations. Hopefully, this understanding will lead to novel approaches with real and convincing clinical efficacy once some of these strategies are tested in carefully performed randomized clinical trials with appropriate power to detect meaningful differences.

Abstract
The genetic lesions that lead to the development of small cell lung carcinoma (SCLC) remain incompletely defined. To identify recurrent allelic deletions in specific chromosomal regions that could serve as markers for tumor suppressor gene (TSG) inactivation in SCLC, we performed a comprehensive allelotype analysis of all 39 nonacrocentric autosomal arms. Alterations in 158 polymorphic microsatellite alleles were examined in 24 pairs of human SCLC tumor and normal control DNA samples. A total of 2,107 informative reactions were analyzed. This analysis revealed allelic losses of 100% on chromosome arm 3p, >85% loss within chromosome arms 13q and 17p, and >70% loss within chromosome arms 4q, 5q, 15q, and 16q. The allelic deletions on chromosome arms 15q and 16q have not been defined previously for SCLC and are candidate regions to harbor novel TSGs. Genes Chromosomes Cancer 27:323-331, 2000.

Abstract
OBJECTIVE Pancreatic islet betacell tumours occur either sporadically or as part of inherited neoplastic syndromes, most commonly multiple endocrine neoplasia (MEN) type 1. Recently, a transgenic mouse model has been established in which the expression of the SV40 large T antigen was targeted to betacells by the rat insulin promoter, leading to the development of multiple pancreatic betacell tumours. In the advanced stages of tumour evolution, these tumours exhibited a high prevalence of loss of heterozygosity (LOH) on mouse chromosomes 9 and 16, at regions syntenic with regions 3q, 3p21, 6q12, 15q24 and 22q of the human genome. DESIGN Loss of heterozygosity in human islet cell tumours was analysed in a PCR based approach at regions of the human genome syntenic with the mouse loci linked to pancreatic betacell tumours as well as the MEN1 gene on chromosome 11q13. These included 35 microsatellite markers in the human chromosomal regions 3q, 3p21, 6q12, 11q13, 15q24 and 22q. PATIENTS 21 patients diagnosed with insulinoma were analysed. Histologically, 16 tumours were benign, while 5 were malignant insulinomas. RESULTS Thirteen of 21 (62%) tumours were found to have loss of genetic material on chromosome 3. The shortest region of overlap implicated a deletion at 3p14.2-3p21 region, corresponding to the marker D3S1295. We did not detect a substantial frequency of LOH in the other syntenic regions, except for the region of MEN 1 gene on 11q13 found to be deleted in 6 (29%) cases, including 3 of 4 tumours from MEN 1 families. Deletions of 3p14. 2-3p21 were observed in 8 of 15 (53%) benign tumours, and in 5 of 6 (83%) malignant neoplasms. CONCLUSIONS These results indicate the high frequency of 3p14.2-3p21 deletions in human pancreatic betacell neoplasms. These finding suggest the presence of a tumour suppressor gene in this region, that may be important in the microevolution of these tumours towards malignancy.

Abstract
Transient pulmonary neuroendocrine cell hyperplasia and non-neuroendocrine lung tumors develop in nitrosaminetreated hamsters, which we hypothesized might modulate epithelial cell phenotype by expressing gene(s) homologous to human chromosome 3p gene(s) deleted in small cell carcinoma of the lung (SCLC). We differentially screened a chromosome 3 library using nitrosamine-treated versus normal hamster lung cDNAs and identified hepatocyte growth factor-like/macrophage-stimulating protein (HGFL/MSP) in injured lung. HGFL/MSP mRNA is low to undetectable in human SCLC and carcinoid tumors, but the HGFL/MSP tyrosine kinase receptor, RON, is present and functional on many of these neuroendocrine tumors. In H835, a pulmonary carcinoid cell line, and H187, a SCLC cell line, HGFL/ MSP induced adhesion/flattening and apoptosis. Using viable cell counts to assess proliferation after 14 d of treatment with HGFL/MSP, there is growth inhibition of H835 but not H187. Nitrosamine-treated hamsters also demonstrate pulmonary neuroendocrine cell apoptosis in situ during the same time period as expression of the endogenous HGFL/ MSP gene, immediately preceding the spontaneous regression of neuroendocrine cell hyperplasia. These observations suggest that HGFL/MSP might regulate neuroendocrine cell survival during preneoplastic lung injury, which could influence the ultimate tumor cell phenotype.

Abstract
Genetic alterations seen in established lung cancers are also often found in premalignant respiratory epithelium. The frequency, usual order, biologic consequences, and prognostic import of the alterations are only beginning to be studied. Increased knowledge regarding pulmonary premalignancy may provide earlier, more treatable endpoints for early detection and therapy.

Abstract
The concept that cells can become malignant upon the elimination of parts of chromosomes inhibiting cell division dates back to Boveri in 1914. Deletions occurring in tumor cells are therefore considered a first indication of possible locations of tumor suppressor gene. Approaches used to localize and identify the paradigm of tumor suppressors, RB1, have also been applied to localize tumor suppressor genes on 3p, the short arm of chromosome 3. This review discusses the methodological advantages and limitations of the various approaches. From a review of the literature on losses of 3p in different types of solid tumors it appears that some tumor types show involvement of the same region, while between others the regions involved clearly differ. Also discussed are results of functional assays of tumor suppression by transfer of part of chromosome 3 into tumor cell lines. The likelihood that a common region of deletions would contain a tumor suppressor is strongly enhanced by coincidence of that region with a chromosome fragment suppressing tumorigenicity upon introduction in tumor cells. Such a situation exists for a region in 3p21.3 as well as for one or more in 3p12-p14. The former region is considered the location of a lung cancer suppressor. The same gene or a different one in the same region may also play a role in the development of other cancers including renal cell cancer. In the latter cancer, there may be additional roles of the VHL region and/or a 3p12-p14 region. The breakpoint region of a t(3;8) originally found to be constitutively present in a family with hereditary renal cell cancer now seems to be excluded from such a role. Specific genes on 3p have been suggested to act as suppressor genes based on either their location in a common deletion region, a markedly reduced expression or presence of aberrant transcripts, their capacity to suppress tumorigenicity upon transfection in to tumor cells, the presumed function of the gene product, or a combination of several of these criteria. A number of genes are evaluated for their possible role as a tumor suppressor according to these criteria. General agreement on such a role seems to exist only for VHL. Though hMLH1 plays an obvious role in the development of specific mismatch repair-deficient cancers, it cannot revert the tumor phenotype and therefore cannot be considered a proper tumor suppressor. The involvement of VHL and MLH1 also in some specific hereditary cancers allowed to successfully apply linkage analysis for their localization. TGFBR2 might well have a tumor suppressor function. It does reduce tumorigenicity upon transfection. Other 3p genes coding for receptor proteins THRB and RARB, are unlikely candidates for tumor suppression. Present observations on a possible association of FHIT with tumor development leave a number of questions unanswered, so that provisionally it cannot be considered a tumor suppressor. Regions that have been identified as crucial in solid tumor development appear to be at the edge of synteny blocks that have been rearranged through the chromosome evolution which led to the formation of human chromosome 3. Although this may merely represent a chance occurrence, it might also reflect areas of genomic instability.

Abstract
A deletion analysis of chromosome 3 was conducted in 72 cases of transitional cell carcinoma of the urinary bladder using seven microsatellites spanning the 3p arm and two additional microsatellites in 3q. Results showed that 19 of 72 (26.4%) cases had deletions in one or more 3p regions. Two regions of frequent deletion were identified: 3p12-14 and 3p21-23. Less frequent deletions at 3p24.2-25 were also observed. Deletions at 3p were weakly correlated with tumor grade, but strongly with pathological stage. Among 70 cases with histological grade available, 4 of 29 (13.8%) grade 1 and 2 tumors, and 15 of 41 (36.6%) grade 3 tumors showed allelic losses in one or more of the 3p regions studied (P = 0.055). Among 69 cases with pathological stage available, none of 27 superficial carcinomas (pTa, pTis, and pT1) showed 3p deletions, whereas 18 of 42 (42.9%) muscle invasive lesions (pT2, pT3, and pT4) displayed allelic losses at 3p (P < 0.001). In addition, 12 cases showed microsatellite instability, but there was no correlation between abnormalities and tumor grade or stage. No correlation was found between deletions at 3p21-23 and microsatellite instability. In conclusion, deletions at three discrete regions of 3p were identified in bladder carcinoma, suggesting the involvement of candidate tumor suppressor genes residing in these regions. Moreover, detection of allelic losses in these regions was associated with higher tumor grade and more advanced stage, suggesting their potential involvement in bladder tumor progression.

Abstract
Chromosomal deletions and translocations of human chromosome region 3p14 are observed in various human malignancies and suggest the existence of a tumor suppressor gene locus within this region. Tumors most frequently affected by these aberrations are small-cell lung cancer and renal-cell carcinoma. In continuation of our previously published YAC contig of chromosome region 3p14.2-p14.3, we report here on the construction of a YAC contig of at least 11 Mb that consisted of 171 YACs and covers the entire subregion 3p14.1. This contig includes the t(3;8) breakpoint of a hereditary renal-cell carcinoma localized in 3p14.2 and extends into human chromosome region 3p12-p13. It defines the order of 34 DNA probes in relation to reference markers D3S6 and D3S30 as well as the human protein tyrosine phosphatase-gamma gene. For 31 DNA probes we identified nonchimeric YACs by fluorescence in situ hybridization. The minimal tilling pathway consists of 16 yeast artificial chromosomes. As a prerequisite for identification of a putative tumor suppressor gene within this region, this contig renders human chromosome region 3p14.1 accessible to gene isolation.

Abstract
We have determined the allelotypes of 215 established lung cancer cell lines by PCR analysis at six loci on the short arm of chromosome 3 (3p): D3S3 (3p12-p13), D3S30 (3p13), D3S2 (3p14-p21.1), D3S32 (3p21), D3F15S2 (3p21), and THRB (3p24). Eighty-seven small cell lung cancer (SCLC), 93 non-small cell lung cancer (NSCLC), 6 extrapulmonary SCLC, 6 mesothelioma, and 23 normal B lymphocyte (BL) cell lines were analyzed. Low levels of heterozygosity at all six 3p loci were seen in both the SCLC and NSCLC cells. SCLC cell lines exhibited the lowest frequencies of heterozygosity at D3S3 (3%), D3S2 (3%), D3F15S2 (10%), and THRB (6%) when compared with frequencies of 8, 42, 48, and 34% at these same loci in the normal population. The lowest frequencies of heterozygosities among the NSCLC cell lines were seen at D3S3 (5%), DF15S2 (17%), and THRB (15%). Adenocarcinoma (Ad) was the only subtype of NSCLC that exhibited any heterozygosity (7%) at D3S3. In addition to D3S3, the lowest frequencies of heterozygosity were seen at D3F15S2 for Ad (9%), D3S2 for large cell carcinomas (8%), and THRB for adenosquamous (0%), bronchioloalveolar (0%), and large cell (8%) carcinomas. In summary, the 3p chromosome region near the D3S3 locus (3p12-p13) appears to be involved in all forms of lung cancer with additional involvement of regions close to the D3S2 (3p14-p21.1), D3F15S2 (3p21), and THRB (3p24) loci.

Abstract
Previous loss of heterozygosity (LOH) studies of chromosome 3p loci have displayed a 60% deletion frequency in non-small-cell lung cancers (NSCLC), as opposed to small-cell lung cancers, in which the 3p deletion is consistently found. However, the high stromal-cell admixture found in NSCLC and the use of the Southern-blot method lead to under-evaluation of this frequency. In this study, we used a very precise microdissection technique followed by PCR amplification of 6 3p21-22 polymorphic genomic sequences to analyze LOH in 86 NSCLC and in normal adjacent tissue. We found the sensitivity of the microdissection-PCR-based LOH technique higher than the sensitivity of the Southern-blot technique: 87% of the squamous-cell carcinomas and 84% of the large-cell undifferentiated carcinomas showed a clear LOH for a 3p21-22 locus. All doubly informative cases but 4 showed concordant deletion at all 3p21-22 loci. The analysis of 3p microsatellite sequences displayed only 2 cases of genomic instability, one of them also displaying features of tumoral heterogeneity as regards the instability genotype. Four carcinomas in situ adjacent to these NSCLC showed the same allelic profile as the invasive tumors. The only prognostic factors in this study were the disease stage and histology. The 3p21-22 deletion was not related to the stage of the disease and did not appear to be a significant prognostic factor of survival. 3p21 loss appears, so far, to be the most frequent and the earliest genetic alteration described in NSCLC, but does not seem to carry significant prognostic information in invasive tumors.

Abstract
In Australia, lung cancer is the most common malignancy in males and the largest cause of cancer deaths. Conventional management has not had a dramatic impact on the mortality rates from lung cancer, which has a case-fatality rate of over 90%. Recent developments in molecular and cellular biology have however, contributed to our knowledge of lung tumorigenesis, which will hopefully translate into clinical benefit for our patients. Many molecular abnormalities are common to both non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC) but there are differences between these histological types and even within the NSCLC subtypes. This review concentrates on NSCLC, which accounts for up to 85% of Australian lung cancers.

Abstract
Cytogenetic and molecular genetic studies have implicated many chromosomal aberrations in the pathogenesis of lung cancer. Deletions on 3p and 9p are presently the primary target for positional cloning of putative tumor suppressor genes. We have recently reported frequent loss of heterozygosity in three separate regions (HRAS, D11S12, D11S16) on 11p in freshly resected lung cancer specimens. Here we report cytogenetic and molecular genetic analyses of 26 permanently growing human lung cancer cell lines. Deletions indicating regions which may harbor potential tumor suppressor genes were found in 5/9 cell lines on 2p, 5/9 on 2q, 6/9 on 3p, 7/9 on 3q, 5/9 on 6q, 3/9 on 9p, 5/9 on 11p, and 6/9 on 13q. Reduction to hemizygosity or a statistically significant increase in the frequency of homozygosity on 11p was found for all markers investigated except for ST5 (D11S832E). Eight of twenty-six (31%) cell lines were hemizygous for D11S12 and 9/26 (35%) for D11S16. Seventeen of eighteen (94%) cell lines were homozygous for PTH (expected homozygosity, 53%), 15/15 (100%) for WT1 (expected homozygosity, 55%), and 16/18 (89%) for CAT (expected homozygosity, 50%). These results confirm the notion that 11p harbors several putative tumor suppressor genes which may become inactivated at different stages of tumor development and progression. They also provide a basis for selecting cell lines for genetic complementation specifically targeted at the regions described.

Abstract
A transplantable tumor and an in vitro culture cell line (GK-T3) were established from metastatic liver tissue of human small cell lung carcinoma (SCLC). Southern blot analysis revealed about 30-fold amplification of c-myc gene in the tumor cells in liver, xenografts, and in vitro cell line. The degree of c-myc amplification was essentially conserved through serial passages in nude mice and cultivation in vitro. The level of c-myc mRNA was significantly increased in these cells. Cytogenetically, numerical and complex structural abnormalities were observed in GK-T3 cells, including t(3p;6p), t(12q;17p), two homogeneously staining regions (hsrs) and several double minutes (dmins). These results suggest that activation of c-myc gene and alteration of gene(s) around these chromosomal breakpoints may play a role in tumorigenesis of GK-T3 SCLC.

Abstract
The rapid pace of research in the genetics of human cancer will predictably render any review of the topic out of date by the time of its publication. Prospects for the near future will likely include the identification of a chromosome 3p gene(s) linked with the development of familial renal cancer and, perhaps, also lung cancer. In addition, the availability from the Human Genome Project of an increasing number of well-characterized markers will accelerate the search for additional human recessive oncogenes. Many questions still remain about the etiology of lung cancer and how to apply this information for patient care. For example, identification of the cell of origin for small cell and non-small cell lung cancers will facilitate our understanding of the development of these tumors and improve the possibilities for future preventive strategies. In addition, we now realize that these cancers arise from the sequential accumulation of multiple genetic mutations (Table 3; Fig. 1). Therefore, a central question is which of these targets are essential for the process of carcinogenesis, and whether there is a critical temporal order for this process with a defined premalignant phase in a discrete field of bronchial tissue. In addition, are there genetically inherited susceptibilities to the development of lung cancer (either directly or via variabilities in carcinogen metabolism) that could be accurately identified in the general population? Finally, is there a rate-limiting mutation and will the genetic correction of this defect suffice to restore growth regulation, or will the replacement of multiple gene products be required for tumor suppression? We are already witnessing the beginnings of the use of molecular diagnostic markers as a research tool for assigning prognostic information. The expression of neuroendocrine markers in non-small cell lung cancer has recently been applied as an indicator of the potential response to combination chemotherapy [15]. Similar methods are being applied to the expression of tumor suppressor genes or the presence of somatic mutations in dominant oncogenes such as the ras gene. However, the clinical benefit of this prognostic information with currently available treatment programs is still uncertain.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
The short arm of chromosome 3 undergoes genetic loss in most small-cell lung cancers and renal cell carcinomas. The most frequently deleted region includes the DNF15S2 locus (mapped to 3p21), suggesting that a putative recessive tumor-suppressor gene might be located nearby. A cosmid clone, cA476, contains the D3S94 locus and two HTF islands and detects a PstI RFLP. We have isolated cDNAs homologous to conserved fragments within cA476; and these cDNAs have 96% sequence similarity to a cDNA derived from the DNF15S2 locus. Sequence information from cDNAs derived from both the rat and pig acyl-peptide hydrolase (E.C.3.4.19.1) gene show that they have a high degree of sequence similarity to cDNAs derived from D3S94 and DNF15S2, suggesting that they are all the same locus. Cosmid cA476 (DNF15S2) has been mapped, by fluorescent in situ hybridization, to chromosome 3p21.3. D3S94 and DNF15S2 are quite distinct from aminoacylase 1 (ACY1), which has been physically linked to D3S2, D3S92, and D3S93, all localized within 3p21.1.

Abstract
Using fluorescence in situ hybridisation (FISH) the chromosomal location and relative order of six human chromosome 3 probes has been determined. The sensitivity of the technique has enabled the relative mapping of probes carrying inserts as small as 500 basepairs (bp), thus allowing the following proximal-distal probe order to be proposed: D3S30 (3p13-14), D3S4 (3p13-14), D3S2 (distal 3p14), D3S32 (3p21), D3S48E (3p21-23), and D3S11 (3p22-23). These data combined with the deletion mapping data of other researchers raise the possibility that the loss of more than one region of the short arm of chromosome 3 may be important in the development of small cell lung cancer.

Abstract
DNA was prepared from normal tissue and 19 lung cancer cell lines. Using probes which detect restriction fragment length polymorphisms at both the topoisomerase II alpha and beta loci, heterozygosity was detected at a frequency of 0.17 and 0.37 for the alpha and beta loci, respectively. Southern blot analysis of DNA extracted from lung cancer cell lines detected amplification of both the topoisomerase II alpha and ERBB2 genes in the adenocarcinoma line Calu3. These results indicate that topoisomerase II alpha and ERBB2 may be closely linked on chromosome 17 and coamplified during adenocarcinoma progression. Since topoisomerase II is a target for several anticancer drugs, it will be of interest to study alterations to topoisomerase II genes during tumour development, as these may in part determine the response of the tumour to chemotherapy.

Abstract
The tumors of patients with lung cancers often show loss of heterozygosity (LOH) at polymorphic loci on the short arm of chromosome 3. Most examples of small-cell lung carcinoma (SCLC) cannot be examined since they are infrequently resected. Small biopsies are, however, usually available from patients with this disease. We have used the polymerase chain reaction (PCR) to study lung tumor biopsies obtained by fiberoptic bronchoscopy and assign the genotype at 11 RFLPs in 7 well-established loci on 3p. We have demonstrated LOH in some and found that biopsy samples need to contain approximately 60% content of tumor cells if LOH is to be reliably detected. One SCLC tumor that we examined has an interstitial 3p deletion proximal to the locus D3F15S2 and thus provides information useful in mapping the position of the tumor suppressor gene on 3p.

Abstract
The functional role of oncogenes in human lung carcinogenesis has been investigated by transfer of activated oncogenes into normal cells or an immortalized bronchial epithelial cell line, BEAS-2B. Transfection of v-Ha-ras, Ki-ras, or the combination of myc and raf into BEAS-2B cells produced tumorigenic cell lines, while transfection of raf or myc alone produced nontumorigenic cell lines. In addition to studying the pathogenic role of oncogenes, we are attempting to define negative growth-regulating genes that have tumor-suppressive effects for human lung carcinomas. Our strategy to identify tumor-suppressor genes involves loss of heterozygosity studies, monochromosome-cell fusion, and cell-cell fusion studies. Loss of heterozygosity studies have revealed consistent allelic DNA sequence deletions on chromosome 17p in squamous cell carcinomas, while large cell carcinomas and adenocarcinomas retained this locus. Mutations in p53, a tumor-suppressor gene located on chromosome 17p, have been observed. Cell-cell hybrid clones produced from fusion of nontumorigenic BEAS-2B cells with tumorigenic HuT292DM cells generally are nontumorigenic. The mechanistic role of the known tumor-suppressor genes Rb-1 and p53 in the development of human lung carcinomas is being investigated in this epithelial cell model of human bronchogenic carcinogenesis.

Abstract
Cytogenetic studies were performed on 27 tumor cell lines (most of which were derived from metastatic lesions) and four fresh malignant pleural and pericardial effusions from 30 patients with non-small-cell lung cancer (non-SCLC). Many clonal structural (deletions and nonreciprocal translocations) and numerical abnormalities were found in each specimen. Statistical analysis revealed these changes were nonrandomly distributed among the chromosomes. A statistically significant number of chromosomal breakpoints were seen in regions 1q1, 1q3, 3p1, 3p2, 3q1, 3q2, 7q1, 13p1, 14p1, 15p1, and 17q1 when the regions were compared to the total haploid complement. In addition, when a given region was compared to other regions within the same chromosome, statistically significant numbers of breakpoints were noted for regions 1q3, 5q1, 7q1, 13p1, 14p1, 15p1, 16q2, 17q1, and 21p1. Specific chromosome bands showing the most frequent involvement in structural abnormalities were (in descending order) 3p14.2, 3q21, 19q13, 11p15, 1q11, 7q11, 1q21, 3p23, and 3p21. The breakpoints indicate areas to look for new dominant oncogenes activated by translocations, while the areas of deletions and loss of material by nonreciprocal translocations highlight areas to search for recessive oncogenes. These cytogenetic studies represent strong evidence that multiple genetic lesions are associated with the development of metastatic lung cancer, and provide a roadmap to search for new genes involved in the pathogenesis of lung cancer.

Abstract
Family history data from an incident case-control study of lung cancer conducted in the Texas Gulf Coast region between 1976 and 1980 were analyzed to evaluate the contribution of cancer in first-degree relatives to lung cancer risk. Odds ratios (OR) increased slightly as the number of relatives with any cancer increased (reaching 1.5 with 4 or more relatives with cancer). Risks were higher for tobacco-related cancers (OR = 1.5 for 2 or more relatives with these tumors) and greatest for first-degree relatives with lung cancer (OR = 2.8 for lung cancer in 2 or more relatives). For cases of squamous cell carcinoma and adenocarcinoma of the lung, risks with 3 or more relatives with any cancer were increased 2-fold (OR = 1.8 and 1.9 respectively), and a significantly elevated risk was found for having a first-degree relative with lung cancer for each histologic type (ORs from 1.7-2.1). Having a spouse with lung cancer increased lung cancer risk (OR = 2.5), and cases with lung cancer reported in a first-degree relative were diagnosed at an earlier age, as were case siblings with lung cancer.

Abstract
The tumors of patients with small cell lung carcinoma (SCLC) frequently exhibit the loss of alleles at polymorphic loci on the short arm of chromosome 3. We report the genotype analysis of six SCLC patients obtained using 15 chromosome 3 probes that identified 19 restriction fragment length polymorphisms (RFLPs). Five of the six patients were reduced to homozygosity in the tumor DNA at every informative 3p locus, and thus did not serve to delineate the deletion. However, the RFLP analysis of the tumor DNA of the sixth patient demonstrated both heterozygous and hemizygous loci on 3p and allowed the definition of an interstitial deletion that extends proximal to the D3S2 locus at 3p14.2-p21 to include at least 3p13-p14. The exclusion of the D3F15S2 locus from the deleted region, observed in this patient, is an uncharacteristic feature of SCLC deletions. This deletion includes the location of D3S30 and D3S4, and thus serves to map these loci within the proximal half of chromosome 3.

Abstract
Two non-small cell carcinoma cell lines from the major histopathologic groups of human lung cancers have been karyotyped: HS-24 was established from a squamous cell carcinoma, and SB-3 was obtained from a metastasis of a poorly differentiated adenocarcinoma. Endoreduplication is characteristic for both cell lines. Subsequent loss of chromosomes led finally to hypotetraploid karyotypes with modal chromosome numbers of 66-68 and 70-72 for HS-24 and SB-3, respectively. The structural analysis was performed by G- and C-banding. Stable overrepresentation of chromosomes 7, 8, 12, and 16 was found. Both cell lines developed a characteristic set of disomic and stable markers. Chromosomes involved in markers were 1, 2, 5, 6, 10, 11, 16, and 17. Consistent numerical and structural normality for chromosomes 4, 18, and 21 was observed.

Abstract
Cytogenetic study of seven cases of previously untreated lung squamous cell carcinomas (SQC) is reported. Chromosome numbers vary from 38 to 538, with a majority of hypotriploid karyotypes with complex rearrangements. The numbers of recurrent imbalances were evaluated in considering the average number of chromosomes or chromosome segments in each analyzed metaphase and for each case. In decreasing order of frequency, deficiencies for 3p, 5q, 8p, Y, 5p, 10p, 13, and, to a lesser degree, for 8q, 9, 10q, 11pter, 14, 15, and 21 were observed; the excesses principally involve 1q, 3q, and 7q. In three tumors, homogeneously staining regions were observed at various chromosome sites. Most chromosome rearrangements occurred after breakage in constitutive heterochromatin, and no recurrent breakpoints were found in euchromatin except 11p15. The major consequences of these anomalies may be chromosomal imbalances, leading to hemizygosity and perhaps related to gene dosage, rather than to alterations of genes.

Abstract
We have used 14 DNA probes, which detect 19 different restriction enzyme length polymorphisms, to search for heterozygosity on chromosome 3 in five cell lines isolated from patients with small cell lung carcinoma. The cell lines on karyotype analysis did not show the deletion in chromosome 3 characteristic of this disease. Our objective was to determine if allelic loss had occurred by some chromosomal mechanism other than deletion. Two of the cell lines are consistent with allelic loss having occurred by whole chromosome loss and reduplication. The third may have lost only the short arm due to i(3q) formation. The fourth cell line has an i(3q) chromosome, together with a translocation product involving the distal portion of the short arm of chromosome 3. Lack of evidence of heterozygosity for this distal portion of 3p suggests that a copy of the 3p homologue is involved in the translocation and therefore does not explain allelic loss of of the other homologue. The fifth, while also likely to have lost one chromosome homologue, has a submicroscopic deletion on all chromosome 3s, only detectable by RFLP analysis. Such homozygous deletions have recently proved useful in the isolation of tumour suppressor genes.

Abstract
10 derivations of rat tracheal epithelial (RTE) cells, including normal cells, normal primary cultures, 7 tumorigenic cell lines and 1 nontumorigenic cell line transformed in vitro by treatment with 7,12-dimethylbenz[a]anthracene (DMBA), benzo[a]pyrene (BP) and/or 12-O-tetradecanoylphorbol-13-acetate (TPA) were examined for oncogene alterations. No abnormalities of Ha-ras or Ki-ras were seen that were suggestive of amplification, rearrangement or the presence of RFLPs. Analysis of specific-point mutations in Ha-ras using Pst I digestion (codon 12, GGA to GCA) or Ha-ras and Ki-ras using Xba I (codon 61, CAA to CTA) were negative. In one cell line derived by DMBA treatment, changes in the c-myc restriction digest pattern were seen after incubation with Bam HI and Hind III. Northern analysis revealed consistent differences between normal and transformed cells when probed with Ha-ras; c-myc expression was of low intensity, and the expression of Ki-ras could not be detected. Transfection of RTE cell DNAs into NIH/3T3 cells did not result in the appearance of morphologic transformants. The studies suggest that Ha-ras or Ki-ras codon 61 A to T transversions (CAA to CTA) are not associated with the immortal/tumorigenic phenotype in RTE cells transformed by DMBA or TPA, and are in contrast to results reported in some other biological systems.

Abstract
An understanding of the molecular pathogenesis of lung cancer has evolved from classic cytogenetic studies and the use of restriction fragment length polymorphisms to encompass the definition of specific genetic abnormalities associated with this disease. Activation of the dominant class of oncogenes is frequent, with involvement of the ras and myc families of genes being the best defined. Several examples of inactivation at specific loci exist and have been related to the presence of tumor suppressor genes, most notably the retinoblastoma gene, p53, and a putative gene located on the short arm of chromosome 3. As our understanding of the nature and interactions between these numerous genetic events evolves, new opportunities for early diagnosis, prevention, and treatment will arise.

Abstract
Von Hippel-Lindau (VHL) disease was initially reported to be linked to the RAF1 oncogene (3p25). We have ascertained and sampled two large multigenerational VHL families for linkage studies, in order to confirm the localization of the VHL gene as a prelude to fine mapping studies. The probes used in the analysis were p627 (RAF1) and pHeA12 (thyroid hormone receptor B) (3p24.1-3p22). VHL was analyzed as an autosomal dominant trait with age-dependent penetrance. The maximum lod score combining both families was z(theta) = 2.16 at theta = 0.0 for RAF1 and z(theta) = 2.20 at theta = 0.05 for thyroid hormone receptor B. Multipoint analysis using the RAF1 and thyroid hormone receptor B loci resulted in a peak lod score of 3.1 confirming linkage of VHL to this region of chromosome 3. However, the position of VHL relative to the two loci could not be established with certainty.

Abstract
Tumor suppressor genes are wild-type alleles of genes that play regulatory roles in cell proliferation, differentiation, and other cellular and systemic processes. It is their loss or inactivation that is oncogenic. The first evidence of tumor suppressor genes appeared in the early 1970s, but only within the past few years has a wealth of new information illuminated the central importance of these genes. Two or more different suppressor genes may be inactivated in the same tumors, and the same suppressors may be inactive in different tumor types (for example, lung, breast, and colon). The suppressor genes already identified are involved in cell cycle control, signal transduction, angiogenesis, and development, indicating that they contribute to a broad array of normal and tumor-related functions. It is proposed that tumor suppressor genes provide a vast untapped resource for anticancer therapy.

Abstract
Allele loss is a hallmark of chromosome regions harboring recessive oncogenes. Lung cancer frequently demonstrates loss of heterozygosity on 17p. Recent evidence suggests that the p53 gene located on 17p13 has many features of such an antioncogene. The p53 gene was frequently mutated or inactivated in all types of human lung cancer. The genetic abnormalities of p53 include gross changes such as homozygous deletions and abnormally sized messenger RNAs along with a variety of point or small mutations, which map to the p53 open reading frame and change amino acid sequence in a region highly conserved between mouse and man. In addition, very low or absent expression of p53 messenger RNA in lung cancer cell lines compared to normal lung was seen. These findings, coupled with the previous demonstration of 17p allele loss in lung cancer, strongly implicate p53 as an anti-oncogene whose disruption is involved in the pathogenesis of human lung cancer.

Abstract
DNA was prepared from tumour and normal tissue from 48 patients representing all common histological types of nonsmall-cell lung cancer. Using eight DNA probes, which detect nine restriction enzyme fragment length polymorphisms (RFLP) on chromosome 3, we established that among the 44 informative patients 32 had lost alleles on the short arm of one of their copies of chromosome 3. Of these 32, at least 13 had also lost alleles on the long arm of chromosome 3, suggesting that the whole chromosome might be lost. For one patient, cytogenetic analysis indicated that the mechanism of allelic loss was reciprocal translocation followed by chromosomal loss of one of the reciprocal products. Two patients with allelic loss distal to the D3S3 locus (which maps to 3p13-14) retained heterozygosity at that locus. These results indicate that loss of alleles on the short arm of chromosome 3 is a common event in lung tumours of the nonsmall-cell type, that this loss occurs by a variety of chromosomal mechanisms, and that the minimally deleted region is 3p13-14----3pter.

Abstract
We have isolated large numbers of human recombinants from a cosmid library constructed from an interspecific (hamster/human) somatic cell hybrid whose only human component is an intact chromosome 3. Unique sequence probes were isolated from these recombinants and were used to localize them along the length of chromosome 3 by hybridization to a somatic cell hybrid deletion panel. We identified two cosmids, cA84 (D3S92) and cA199 (D3S93), derived from within chromosomal band 3p21.1. Both cosmids contained multiple rare restriction sites that were tightly clustered within the cosmids. We have therefore identified, in a region consistently deleted in a variety of lung cancers, two cosmids that may contain genes that are candidates for involvement in lung cancer.

Abstract
Activation of protooncogenes and inactivation of putative tumor suppressor genes are genetic lesions considered to be important in lung carcinogenesis. Fifty-four cases of non-small-cell lung cancer (23 adenocarcinomas, 23 squamous-cell carcinomas, and 8 large-cell carcinomas) were examined for loss of DNA sequences at 13 polymorphic genetic loci. Loss of heterozygosity was seen more frequently in squamous-cell carcinoma than in adenocarcinoma. The loss of DNA sequences from the short arm of chromosome 17 (D17S1 locus) was detected in 8 of 9 heterozygous cases of squamous-cell carcinoma and in only 2 of 11 heterozygous cases of adenocarcinomas. Furthermore, in 7 of these 8 squamous-cell carcinomas, loss of heterozygosity from chromosome 17 was accompanied by loss of DNA sequences from chromosome 11. The spectrum of allelic sequences lost from chromosome 11 was, however, similar in every type of carcinoma studied, and the data show two regions commonly deleted from chromosome 11 (11pter-p15.5 and 11p13-q13) that may have a role in the pathogenesis of all these types of non-small-cell bronchogenic carcinoma. Loss of DNA sequences from chromosome 3 was seen in 16 of 31 cases where the constitutive DNA was heterozygous-i.e., informative. These data included only 6 of 16 cases where loss of heterozygosity involved a chromosomal locus previously shown to be lost consistently in small-cell lung cancer (DNF15S2). Loss of heterozygosity at the chromosome 13q locus, D13S3, was seen in 9 of 21 informative cases, and in 2 cases, both adenocarcinomas, duplication of the intact DNA sequences suggested the possibility that mitotic recombination had occurred. Frequent DNA sequence deletions, including those from chromosome 17, in squamous-cell carcinomas may reflect the extensive mutagenic and clastogenic effects of tobacco smoke that may lead to inactivation of putative tumor-suppressor genes.

Abstract
To examine the extent and variation of allelic loss in a common adult tumor, polymorphic DNA markers were studied from every nonacrocentric autosomal arm in 56 paired colorectal carcinoma and adjacent normal colonic mucosa specimens. This analysis was termed an allelotype, in analogy with a karyotype. Three major conclusions were drawn from this analysis: (i) Allelic deletions were remarkably common; one of the alleles of each polymorphic marker tested was lost in at least some tumors, and some tumors lost more than half of their parental alleles. (ii) In addition to allelic deletions, new DNA fragments not present in normal tissue were identified in five carcinomas; these new fragments contained repeated sequences of the variable number of tandem repeat type. (iii) Patients with more than the median percentage of allelic deletions had a considerably worse prognosis than did the other patients, although the size and stage of the primary tumors were very similar in the two groups. In addition to its implications concerning the genetic events underlying tumorigenesis, tumor allelotype may provide a molecular tool for improved estimation of prognosis in patients with colorectal cancer.

Abstract
Previous studies have shown that c-Ha-ras-1 and other genes located on the short arm of chromosome 11 are frequently lost in a number of human tumors. We investigated whether similar losses of the c-Ha-ras-1 allele occurred in human squamous cell carcinomas (SCCs) and basal cell carcinomas (BCCs). DNAs were isolated from 35 pairs of skin tumors (25 BCCs and 10 SCCs) and matching normal skin from the same patients and analyzed for c-Ha-ras gene polymorphism by Southern blot hybridization. Sixteen BCC patients and 1 SCC patient were constitutionally heterozygous for the c-Ha-ras gene in their normal skin DNA. Of these 17 patients, five patients (four with BCC and one with SCC) (29%) showed loss of one of the c-Ha-ras alleles in their tumor DNA. One of the constitutionally heterozygous BCC patients exhibited deletion of the 6.6-kb c-Ha-ras allele and an extra copy of the 7.8-kb allele. In summary, loss of heterozygosity at the c-Ha-ras locus occurred frequently (29%) in the 17 human skin cancers studied. However, our finding that 90% of the patients with SCC, as opposed to 36% of the patients with BCC, had only one of the c-Ha-ras alleles in their normal skin tissue requires further study. Whether c-Ha-ras homozygosity has any bearing on genetic susceptibility to SCC remains to be established.

Abstract
Small cell lung cancer (SCLC) has been associated with loss of heterozygosity at several distinct genetic loci including chromosomes 3p, 13q, and 17p. To determine whether the retinoblastoma gene (Rb) localized at 13q14, might be the target of recessive mutations in lung cancer, eight primary SCLC tumors and 50 cell lines representing all major histologic types of lung cancer were examined with the Rb complementary DNA probe. Structural abnormalities within the Rb gene were observed in 1/8 (13%) primary SCLC tumors, 4/22 (18%) SCLC lines, and 1/4 (25%) pulmonary carcinoid lines (comparable to the 20 to 40% observed in retinoblastoma), but were not detected in other major types of lung cancer. Rb messenger RNA expression was absent in 60% of the SCLC lines and 75% of pulmonary carcinoid lines, including all samples with DNA abnormalities. In contrast, Rb transcripts were found in 90% of non-SCLC lung cancer lines and in normal human lung. The finding of abnormalities of the Rb gene in SCLC and pulmonary carcinoids (both neuroendocrine tumors) suggests that this gene may be involved in the pathogenesis of a common adult malignancy.
