Abstract
FUS1/TUSC2 (FUSion1/TUmor Suppressor Candidate 2) is a tumor suppressor gene (TSG) originally described as a member of the TSG cluster from human 3p21.3 chromosomal region frequently deleted in lung cancer. Its role as a TSG in lung, breast, bone, and other cancers was demonstrated by several groups, but molecular mechanisms of its activities are starting to unveil lately. They suggest that Fus1-dependent mechanisms are relevant in etiologies of diseases beyond cancer, such as chronic inflammation, bacterial and viral infections, premature aging, and geriatric diseases. Here, we revisit the discovery of FUS1 gene in the context of tumor initiation and progression, and review 20 years of research into FUS1 functions and its molecular, structural, and biological aspects that have led to its use in clinical trials and gene therapy. We present a data-driven view on how interactions of Fus1 with the mitochondrial Ca2+ (mitoCa2+) transport machinery maintain cellular Ca2+ homeostasis and control cell apoptosis and senescence. This Fus1-mediated cellular homeostasis is at the crux of tumor suppressor, anti-inflammatory and anti-aging activities.

Abstract
The increase in the life expectancy of patients with renal cell carcinoma (RCC) in the last decade is due to changes that have occurred in the area of preclinical studies. Understanding cancer pathophysiology and the emergence of new therapeutic options, including immunotherapy, would not be possible without proper research. Before new approaches to disease treatment are developed and introduced into clinical practice they must be preceded by preclinical tests, in which animal studies play a significant role. This review describes the progress in animal model development in kidney cancer research starting from the oldest syngeneic or chemically-induced models, through genetically modified mice, finally to xenograft, especially patient-derived, avatar and humanized mouse models. As there are a number of subtypes of RCC, our aim is to help to choose the right animal model for a particular kidney cancer subtype. The data on genetic backgrounds, biochemical parameters, histology, different stages of carcinogenesis and metastasis in various animal models of RCC as well as their translational relevance are summarized. Moreover, we shed some light on imaging methods, which can help define tumor microstructure, assist in the analysis of its metabolic changes and track metastasis development.

Abstract
In 2012, an estimated 64,770 men and women were diagnosed with malignancy of the kidney and renal pelvis, of which 13,570 succumbed to their disease. Common genetic aberrations in renal cell carcinomas (RCCs) include loss of function of the VHL gene in clear-cell RCC, overexpression of the c-MET gene in papillary RCC type I, deficiency in the FH gene in papillary RCC type II and loss of heterozygozity of the BHD gene in chromophobe RCC. Recent studies illustrate epigenetic silencing of VHL, as well as alterations in histone modifications and their governing enzymes. The possibility of reversing these epigenetic marks has resulted in efforts to target these changes by utilizing inhibitors of HDACs, DNA methyltransferases and, recently, histone methyltransferases in preclinical and clinical studies. This article focuses on potential therapeutic interventions, and the implications of histone modifications and related enzyme alterations in RCC.

Abstract
Despite numerous studies reporting deregulated microRNA (miRNA) and gene expression patterns in clear cell renal cell carcinoma (ccRCC), no direct comparisons have been made to its presumed normal counterpart: the renal proximal tubular epithelial cells (PTECs). The aim of this study was to determine the miRNA expression profiles of 10 ccRCC-derived cell lines and short-term cultures of PTEC and to correlate these with their gene expression and copy-number profiles. Using microarray-based methods, a significantly altered expression level in ccRCC cell lines was observed for 23 miRNAs and 1630 genes. The set of miRNAs with significantly decreased expression levels include all members of the miR-200 family known to be involved in the epithelial to mesenchymal transition process. Expression levels of 13 of the 47 validated target genes for the downregulated miRNAs were increased more than twofold. Our data reinforce the importance of the epithelial to mesenchymal transition process in the development of ccRCC.

Abstract
Background Inactivaion of tumor suppressor genes (TSGs) by promoter CpG methylation frequently occurs in tumorigenesis, even in the early stages, contributing to the initiation and progression of human cancers. Deleted in lung and esophageal cancer 1 (DLEC1), located at the 3p22-21.3 TSG cluster, has been identified frequently silenced by promoter CpG methylation in multiple carcinomas, however, no study has been performed for lymphomas yet. Methods We examined the expression of DLEC1 by semi-quantitative reverse transcription (RT)-PCR, and evaluated the promoter methylation of DLEC1 by methylation-specific PCR (MSP) and bisulfite genomic sequencing (BGS) in common lymphoma cell lines and tumors. Results Here we report that DLEC1 is readily expressed in normal lymphoid tissues including lymph nodes and PBMCs, but reduced or silenced in 70% (16/23) of non-Hodgkin and Hodgkin lymphoma cell lines, including 2/6 diffuse large B-cell (DLBCL), 1/2 peripheral T cell lymphomas, 5/5 Burkitt, 6/7 Hodgkin and 2/3 nasal killer (NK)/T-cell lymphoma cell lines. Promoter CpG methylation was frequently detected in 80% (20/25) of lymphoma cell lines and correlated with DLEC1 downregulation/silencing. Pharmacologic demethylation reversed DLEC1 expression in lymphoma cell lines along with concomitant promoter demethylation. DLEC1 methylation was also frequently detected in 32 out of 58 (55%) different types of lymphoma tissues, but not in normal lymph nodes. Furthermore, DLEC1 was specifically methylated in the sera of 3/13 (23%) Hodgkin lymphoma patients. Conclusions Thus, methylation-mediated silencing of DLEC1 plays an important role in multiple lymphomagenesis, and may serve as a non-invasive tumor marker for lymphoma diagnosis.

Abstract
CONTEXT The diagnosis of primary renal cell carcinomas (RCCs) with both papillary architecture and cells with clear cytoplasm can be diagnostically challenging for practicing pathologists. The 4 main neoplasms in the differential diagnosis are clear cell RCC, papillary RCC, clear cell papillary RCC, and Xp11 translocation RCC. Accurate diagnosis has both prognostic and therapeutic implications. OBJECTIVE To highlight the helpful cytomorphologic, immunohistochemical, and cytogenetic features of each of these entities to enable reproducible classification. DATA SOURCES Published peer-reviewed literature was reviewed, accompanied by the authors' personal experiences. CONCLUSIONS Key morphologic clues and a focused immunohistochemical panel, including CK7, α-methylacyl coenzyme A racemase (AMACR), TFE3, cathepsin K, and carbonic anhydrase IX (CAIX), now allow most resected RCCs with papillary architecture and clear cells to be accurately classified. In other cases, cytogenetic and molecular findings can establish the diagnosis. Despite these tools, some RCCs with papillary architecture and clear cells do not fit into any of the described entities and currently remain unclassified.

Abstract
Sporadic clear cell renal cell carcinoma (cRCC) is genetically characterized by the recurrent loss of the short arm of chromosome 3, with a hotspot for copy number loss in the 3p21 region. We applied a method called "gene identification by nonsense-mediated mRNA decay inhibition" to a panel of 10 cRCC cell lines with 3p21 copy number loss to identify biallelic inactivated genes located at 3p21. This revealed inactivation of the histone methyltransferase gene SETD2, located on 3p21.31, as a common event in cRCC cells. SETD2 is nonredundantly responsible for trimethylation of the histone mark H3K36. Consistent with this function, we observed loss or a decrease of H3K36me3 in 7 out of the 10 cRCC cell lines. Identification of missense mutations in 2 out of 10 primary cRCC tumor samples added support to the involvement of loss of SETD2 function in the development of cRCC tumors.

Abstract
BACKGROUND The human fragile histidine triad (FHIT) gene is a putative tumor suppressor gene, which is located at chromosome region 3p14.2. It was suggested that the loss of heterozygosity (LOH), homozygous deletions, and abnormal expression of the FHIT gene were involved in several types of human malignancies. MATERIALS AND METHODS To determine the role of FHIT in various cancers, we have performed structural and functional analysis of FHIT in detail. RESULTS AND DISCUSSION The protein FHIT catalyzes the Mg(2+) dependent hydrolysis of P1-5 cent-O-adenosine-P3-5 cent-O-adenosine triphosphate, Ap3A, to AMP, and ADP. The reaction is thought to follow a two-step mechanism. Histidine triad proteins, named for a motif related to the sequence H-cent-H-cent-H-cent-cent- (cent, a hydrophobic amino acid), belong to superfamily of nucleotide hydrolases and transferases. This enzyme acts on the R-phosphate of ribonucleotides, and contain a approximately 30-kDa domain that is typically a homodimer of approximately 15 kDa polypeptides with catalytic site. CONCLUSION Here we have gathered information is known about biological activities of FHIT, the structural and biochemical bases for their functions. Our approach may provide a comparative framework for further investigation of FHIT.

Abstract
Abstract
Purpose: Claudin-1 is a tight junction protein described in normal tissues as well as in malignancies. We aimed to assess the diagnostic or prognostic significance of claudin-1 expression in renal cell carcinoma and to correlate the expression of claudin-1 with clinical, histopathologic, and prognostic parameters in renal cell carcinoma.
Experimental Design: A tissue microarray was constructed using formalin-fixed, paraffin-embedded tissue from renal cell carcinomas and corresponding normal renal tissue from 318 patients. The protein expression of claudin-1 was assessed and correlated to clinicopathologic tumor parameters including patient survival. A separate cohort of 44 papillary renal cell carcinoma was used for validation of results.
Results: Claudin-1 was expressed in 29.9% of renal cell cancer cases. Whereas the vast majority of clear cell carcinomas were negative for claudin-1, most papillary tumors (76-86%) were positive. Claudin-1 expression was associated with markers of unfavorable tumor biology in clear cell renal cell carcinoma, whereas the opposite was valid for papillary renal cell carcinoma. In clear cell renal cell carcinoma claudin-1 positivity was a prognosticator of shortened disease-specific patient survival in univariate analysis (P = 0.008), which also remained significant in multivariate analyses in the clinically important subgroups of nonmetastasized or asymptomatic patients.
Conclusions: Claudin-1 is expressed in the majority of papillary renal cell carcinomas, suggesting a diagnostic value of this marker. Its expression is an independent prognosticator of shortened disease-specific patient survival in clinically relevant subgroups of clear cell renal cell carcinoma. Further functional studies are needed to clarify the different biological roles of claudin-1 expression in these histologic subtypes of renal cell carcinoma.

Abstract
CONTEXT Deletion of the short arm of chromosome 3 (3p deletion) is a cytogenetic abnormality generally associated with clear cell renal cell carcinoma, the most aggressive form of renal epithelial tumor. OBJECTIVE To cytogenetically characterize 24 renal tumors in order to check the incidence and the type of 3p deletions, as well as to identify new genes putatively participating in renal tumorigenesis and test the protein products of the von Hippel-Lindau (VHL) and fragile histidine triad (FHIT) genes. DESIGN We analyzed 24 renal tumors by conventional cytogenetics, comparative genomic hybridization, and fluorescence in situ hybridization. We then performed a comparative expression study of the proteins pVHL and Fhit. RESULTS In our series of 24 renal tumors, the 3p deletion was the most frequent genetic alteration (15/24); the other features were partial trisomy 5q, 8p deletion, and monosomy 9 and 14. The 3p deletion was long and terminal, and no interstitial deletion was identified. By immunohistochemistry, we found that for the 2 genes of interest, VHL and FHIT, loss or decrease in protein expression were very frequently observed in clear cell renal cell carcinoma and not always associated with a 3p deletion (14/20 in clear cell renal cell carcinoma). CONCLUSIONS Our studies characterize the 3p deletion as long and terminal and identify no interstitial deletion in that chromosome. Fhit and pVHL protein expression loss appear to be independent, as they can be dissociated. Our data are supportive of a role for FHIT (in addition to VHL) in renal tumorigenesis. No other gene with particular potential interest in renal tumorigenesis could be identified among the selected genes.

Abstract
We have previously found that the borders of evolutionarily conserved chromosomal regions often coincide with tumor-associated deletion breakpoints within human 3p12-p22. Moreover, a detailed analysis of a frequently deleted region at 3p21.3 (CER1) showed associations between tumor breaks and gene duplications. We now report on the analysis of 54 chromosome 3 breaks by multipoint FISH (mpFISH) in 10 carcinoma-derived cell lines. The centromeric region was broken in five lines. In lines with highly complex karyotypes, breaks were clustered near known fragile sites, FRA3B, FRA3C, and FRA3D (three lines), and in two other regions: 3p12.3-p13 ( approximately 75 Mb position) and 3q21.3-q22.1 ( approximately 130 Mb position) (six lines). All locations are shown based on NCBI Build 36.1 human genome sequence. The last two regions participated in three of four chromosome 3 inversions during primate evolution. Regions at 75, 127, and 131 Mb positions carry a large ( approximately 250 kb) segmental duplication (tumor break-prone segmental duplication [TBSD]). TBSD homologous sequences were found at 15 sites on different chromosomes. They were located within bands frequently involved in carcinoma-associated breaks. Thirteen of them have been involved in inversions during primate evolution; 10 were reused by breaks during mammalian evolution; 14 showed copy number polymorphism in man. TBSD sites showed an increase in satellite repeats, retrotransposed sequences, and other segmental duplications. We propose that the instability of these sites stems from specific organization of the chromosomal region, associated with location at a boundary between different CG-content isochores and with the presence of TBSDs and "instability elements," including satellite repeats and retroviral sequences.

Abstract
von Hippel-Lindau disease (VHL) is a rare autosomal-dominant disorder in which affected individuals develop tumors in a number of locations. It occurs at a frequency of one per 36,000 population. Metastatic renal cell carcinoma (RCC) remains the leading cause of mortality in patients with clear cell RCC arising from mutations in the VHL tumor suppressor. RCC is the presenting feature in only 10% of VHL patients. VHL patients can present with a number of other renal lesions, such as hemangiomas and benign adenomas, in addition to simple cysts and RCC. We have investigated VHL gene mutations in familial RCC. The study cohort consisted of four patients with synchronous VHL and RCC and 31 kindreds. Analysis of the chromosomes was performed by the Moorehead method. Although none of the kindreds investigated had clinical evidence of VHL disease, 22 were found to have a VHL gene mutation consisting of deletions on the short arm of chromosomes 3, 17, and 19. Detailed clinical examination of the 22 kindreds with a VHL mutation revealed cerebellar hemangioblastoma (three kindreds), meningioma (two) and renal cell carcinoma (five). No VHL gene mutation was detected in nine kindreds. The prevalence of VHL gene mutations was 70.9% in the familial RCC kindreds. As a result of this study, the kindreds of patients with synchronous VHL and RCC have undergone molecular genetic testing and should be investigated for associated disorders.

Abstract
We show here that the promoter of E2F1 gene, encoding one of the key regulators of cell proliferation, is overly active in the presence of low amounts of triiodothyronine (T3) and in the presence of mutant thyroid hormone receptor. We also show that T3-thyroid hormone receptor pathway of regulation of molecular processes is disturbed in clear cell renal cell carcinoma (ccRCC) on several levels, including overexpression of thyroid hormone receptors and the disturbance of their binding to DNA and to the hormone. In comparison to the cancer-free kidneys and peritumoral respective control tissues, E2F1 mRNA and protein levels are significantly increased in cancer tissues. A significant correlation between E2F1 mRNA and protein levels has been found in both control types and ccRCCs. No correlation was observed between the amount of E2F1 mRNA and the amount of thyroid hormone receptors or their DNA or T3 binding activity, suggesting that the function of thyroid hormone receptors could be markedly disturbed in both tumor and peritumoral cells. In summary, we show that ccRCC is characterized by the overexpression of E2F1, which is likely a result of a deregulated control of T3-dependent molecular processes.

Mandatory chromosomal segment balance in aneuploid tumor cells. BMC Cancer 2007; 7:21.

Abstract
BACKGROUND Euploid chromosome balance is vitally important for normal development, but is profoundly changed in many tumors. Is each tumor dependent on its own structurally and numerically changed chromosome complement that has evolved during its development and progression? We have previously shown that normal chromosome 3 transfer into the KH39 renal cell carcinoma line and into the Hone1 nasopharyngeal carcinoma line inhibited their tumorigenicity. The aim of the present study was to distinguish between a qualitative and a quantitative model of this suppression. According to the former, a damaged or deleted tumor suppressor gene would be restored by the transfer of a normal chromosome. If so, suppression would be released only when the corresponding sequences of the exogenous normal chromosome are lost or inactivated. According to the alternative quantitative model, the tumor cell would not tolerate an increased dosage of the relevant gene or segment. If so, either a normal cell derived, or, a tumor derived endogenous segment could be lost. METHODS Fluorescence in Situ Hybridization based methods, as well as analysis of polymorphic microsatellite markers were used to follow chromosome 3 constitution changes in monochromosomal hybrids. RESULTS In both tumor lines with introduced supernumerary chromosomes 3, the copy number of 3p21 or the entire 3p tended to fall back to the original level during both in vitro and in vivo growth. An exogenous, normal cell derived, or an endogenous, tumor derived, chromosome segment was lost with similar probability. Identification of the lost versus retained segments showed that the intolerance for increased copy number was particularly strong for 3p14-p21, and weaker for other 3p regions. Gains in copy number were, on the other hand, well tolerated in the long arm and particularly the 3q26-q27 region. CONCLUSION The inability of the cell to tolerate an experimentally imposed gain in 3p14-p21 in contrast to the well tolerated gain in 3q26-q27 is consistent with the fact that the former is often deleted in human tumors, whereas the latter is frequently amplified. The findings emphasize the importance of even minor changes in copy number in seemingly unbalanced aneuploid tumors.

Abstract
PURPOSE We developed a rapid interphase fluorescence in situ hybridization (FISH) test to differentiate renal cell carcinoma (RCC) based on known genetic alterations and verified the suitability of this test for practical use. MATERIALS AND METHODS We composed 2 FISH test sets using 6 centromere specific and 2 region specific DNA probes of human chromosomes. Test set 1 contained centromeric probes for chromosomes 1, 2, 6 and 9, as labeled by 4 fluorescence dyes. For test set 2 we chose 3p24pter and 3p13p14 regions, and centromeric probes of chromosomes 7 and 17. Interphase nuclei of tumor specimens were prepared from 50 mum frozen tissue sections and fixed on slides. The 2 sets were hybridized simultaneously side by side on the same slide. RESULTS Seven clear cell carcinomas, 8 papillary carcinomas, 7 chromophobe RCCs and 3 oncocytomas were analyzed by interphase FISH. Results were compared with comparative genomic hybridization findings and pathological reports. Genetic alterations were detected in 22 of 25 analyzed tumors by FISH. FISH findings absolutely correlated with comparative genomic hybridization results. Of the analyzed carcinomas 22 could be identified correctly. In 3 tumors the histological subtypes were revised. CONCLUSIONS The results of this study demonstrate that the performed test set allows the accurate identification of RCC in 1 hybridization step. Therefore, FISH represents an effective method for the rapid classification of RCC.

Abstract
The ADAMTSs (a disintegrin and metalloproteinase with thrombospondin motifs) are a group of proteases that are found both in mammals and invertebrates. Since the prototype ADAMTS-1 was first described in 1997, there has been a rapidly expanding body of literature describing this gene family and the proteins they encode. The complete human family has 19 ADAMTS genes, together with three members of a newly identified subgroup, the ADAMTSL (ADAMTS-like) proteins, which have several domains in common with the ADAMTSs. The ADAMTSs are extracellular, multidomain enzymes whose known functions include: (i) collagen processing as procollagen N-proteinase; (ii) cleavage of the matrix proteoglycans aggrecan, versican and brevican; (iii) inhibition of angiogenesis; and (iv) blood coagulation homoeostasis as the von Willebrand factor cleaving protease. Roles in organogenesis, inflammation and fertility are also apparent. Recently, some ADAMTS genes have been found to show altered expression in arthritis and various cancers. This review highlights progress in understanding the structural organization and functional roles of the ADAMTSs in normal and pathological conditions.

Abstract
Here we report the complex pattern of genomic imbalances and rearrangements in a panel of 19 renal cell carcinoma cell lines detected with molecular cytogenetic analysis. Consistent heterogeneity in chromosome number was found, and most cell lines showed a near-triploid chromosome complement. Several cell lines showed deletions of the TP53 (alias p53), CDKN2A (alias p16), and VHL genes. Multiplex fluorescence in situ hybridization (M-FISH) analysis revealed chromosome 3 translocated to several other partners chromosomes, as well as breakage events commonly affecting chromosomes 1, 5, 8, 10, and 17. The most common abnormality detected with comparative genomic hybridization (CGH) was deletions of chromosome 3p, with loss of the RASSF1, FHIT, and p44S10 loci frequently involved. CGH gain of 5q showed overrepresentation of the EGR1 and CSF1R genes. Recurrent alterations to chromosome 7 included rearrangement of 7q11 and gains of the EGFR, TIF1, and RFC2 genes. Several lines exhibited rearrangement of 12q11 approximately q14 and overrepresentation of CDK4 and SAS loci. M-FISH revealed several other recurrent translocations, and CGH findings included loss of 9p, 14q, and 18q and gain of 8q, 12, and 20. Further genomic microarray changes included loss of MTAP, IGH@, HTR1B, and SMAD4 (previously MADH4) and gains of MYC and TOP1. An excellent correlation was observed between the genomic array and FISH data, demonstrating that this technique is effective and accurate. The aberrations detected here may reflect important pathways in renal cancer pathogenesis.

Abstract
Renal cell carcinomas (RCC) in adults are histologically heterogeneous solid tumors with specific chromosomal abnormality patterns included in the World Health Organization (WHO) classification. To overcome some of the drawbacks of cytogenetic and comparative genomic hybridization (CGH) analyses, we designed a first-generation cytogenetic diagnostic test using four-color fluorescence in situ hybridization (FISH) on interphase nuclei. We selected 51 bacterial artificial chromosome and P1-derived artificial chromosome clones covering 17 chromosomal regions involved in the abnormalities of the adult RCC histologic subtypes. An initial set of probes allowed the identification of clear-cell RCC, papillary RCC, and other RCC on a single slide. A second test allowed the detection of additional chromosomal abnormalities or aberrations specific to chromophobic RCC and oncocytomas. We tested 25 cases of RCC, and the results were in agreement with those of cytogenetic techniques and/or CGH methods. The techniques appeared to be very sensitive, because small tumoral cell clones that were undetected by other cytogenetic methods were identified with this method. It was concluded that the multicolor FISH test was specific and sensitive, easy to perform, and could be part of the investigation process in RCC.

Abstract
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<3-10(-7)). This observation suggests that tumour suppressor genes (TSG) in these regions could have a synergistic effect. The exceptionally high frequency of chromosome aberrations in NLJ-003 and NL3-001 loci suggests that multiple TSG(s) involved in different malignancies are located very near to these markers. Precise mapping of 15 independent HDs in the LUCA region allowed us to establish the smallest HD region in 3p21.3C located between D3S1568 (CACNA2D2 gene) and D3S4604 (SEMA3F gene). This region contains 17 genes. Mapping of 19 HDs in the AP20 region resulted in the localization of the minimal region to the interval flanked by D3S1298 and D3S3623 markers. Only four genes were discovered in this interval, namely, APRG1, ITGA9, HYA22 and VILL.

Abstract
PURPOSE OF REVIEW The combination of several recent molecular technologies, including comparative genomic hybridization, fluorescence in-situ hybridization and complementary DNA and tissue microarrays, has advanced our understanding of renal cancer. However, a great deal of information regarding the genetics of renal neoplasms has also emerged from the extensive cytogenetic investigations in the past decade. RECENT FINDINGS The correlation between cytogenetic or molecular genetic abnormalities and histomorphology is most consistent in clear cell and papillary types of renal cell carcinoma. However, gene expression profile studies have brought new insights into the classification of renal tumors, and may provide new markers that identify patients with a poor prognosis as well as identifying potential therapeutic targets. SUMMARY The integration of expression profile data and clinical parameters could serve to enhance the diagnosis and prognosis of renal cell carcinoma. The identification and evaluation of new molecular parameters will be necessities in cancer research and cancer treatment.

Abstract
In all, 31 renal cell carcinomas (RCCs) were examined for expression of the potential tumour suppressor LRIG1 (formerly Lig-1) and the epidermal growth factor receptor (EGFR). Eight matched samples of uninvolved kidney cortex were also evaluated. Gene expression was examined by quantitative real-time RT–PCR. In the eight matched sample pairs (uninvolved kidney cortex and tumour), protein expression was examined by immunohistochemistry. Conventional (clear cell) tumours showed an expected upregulation of EGFR. LRIG1 expression was generally downregulated in conventional and papillary RCC but not in chromophobic RCC. The ratio between EGFR and LRIG1 was more than 2.5-fold higher in the eight tumours compared with matched uninvolved kidney cortex and was at least two-fold higher than the mean normal ratio in 21 of 31 samples analysed. The observed downregulation of LRIG1 and increased EGFR/LRIG1 ratios are consistent with LRIG1 being a suppressor of oncogenesis in RCC by counteracting the tumour-promoting properties of EGFR. Further studies are justified to elucidate the explicit role of LRIG1 in the oncogenesis of RCC.

Abstract
By positional cloning, we identified two breakpoint-spanning genes in a familial clear cell renal cell carcinoma (CCRCC)-associated t(1;3)(q32.1;q13.3): LSAMP and NORE1 (RASSF1 homolog). Both genes are downregulated in 9 of 9 RCC cell lines. While the NORE1A promoter predominantly presents partial methylation in 6 of the cell lines and 17/53 (32%) primary tumors, the LSAMP promoter is completely methylated in 5 of 9 cell lines and in 14/53 (26%) sporadic and 4 familial CCRCCs. Expression of LSAMP and NORE1A proteins in CCRCC cell lines inhibited cell proliferation. These characteristics indicate that LSAMP and NORE1A may represent new candidate tumor suppressors for CCRCC.

Abstract
We report chromosome 3p deletion mapping of 32 cervical carcinoma (CC) biopsies using 26 microsatellite markers located in frequently deleted 3p regions to detect loss of heterozygosity and homozygous loss. In addition, two STS markers (NLJ-003 and NL3-001) located in the 3p21.3 telomeric (3p21.3T) and 3p21.3 centromeric (3p21.3C) regions, respectively, were used for quantitative real-time PCR as TaqMan probes. We show that quantitative real-time PCR is reliable and sensitive and allows discriminating between 0, 1 and 2 marker copies per human genome. For the first time, frequent (five of 32 cases, i.e. 15.6%) homozygous deletions were demonstrated in CCs in both 3p21.3T and 3p21.3C regions. The smallest region homozygously deleted in 3p21.3C was located between D3S1568 (CACNA2D2 gene) and D3S4604 (SEMA3F gene) and contains 17 genes previously defined as lung cancer candidate Tumor suppressor genes (TSG(s)). The smallest region homozygously deleted in 3p21.3T was flanked by D3S1298 and NL1-024 (D3S4285), excluding DLEC1 and MYD88 as candidate TSGs involved in cervical carcinogenesis. Overall, this region contains five potential candidates, namely GOLGA4, APRG1, ITGA9, HYA22 and VILL, which need to be analysed. The data showed that aberrations of either NLJ-003 or NL3-001 were detected in 29 cases (90.6%) and most likely have a synergistic effect (P<0.01). The study also demonstrated that aberrations in 3p21.3 were complex and in addition to deletions, may involve gene amplification as well. The results strongly suggest that 3p21.3T and 3p21.3C regions harbor genes involved in the origin and/or development of CCs and imply that those genes might be multiple TSG(s).

Abstract
The kidney is a frequent site for chemically induced cancers in rodents and among the 10 most frequent sites for cancer in human patients. Renal cell carcinoma (RCC) is the most frequent upper urinary tract cancer in humans and accounts for 80-85% of malignant renal tumors. Hereditary RCC occurs in Eker rats that are heterozygous for an insertion mutation in the Tsc2 tumor suppressor gene. The germline mutation renders heterozygous mutants highly susceptible to renal carcinogens. The utility of this model in studying potential renal carcinogens is due to an ordered progression of proliferative renal lesions that can be identified and counted microscopically. The quantitative nature of the model allows for the production of statistically powerful data to understand the relative degree and potency of chemical effects and allow analysis of genetic alterations that may be chemical specific.

Abstract
To ascertain the involvement of human chromosome 3p and its established critical TSG regions in various epithelial malignancies, 21 polymorphic and 2 nonpolymorphic 3p markers were allelotyped in nonpapillary RCC, NSCLC, CC and BC from a total of 184 patients. LOH was observed with high frequency in all types of cancer studied: RCC (52/57, 91%), BC (41/51, 80%), NSCLC (30/40, 75%) and CC (27/36, 75%). Interstitial deletions, believed to signal TSG inactivation, were verified using the "L-allele rule" and real-time quantitative PCR. Significant correlation was observed between DNA copy numbers for 2 nonpolymorphic STS markers and LOH data for adjacent polymorphic loci. Interstitial deletions in 3p were demonstrated for all cancer types studied. However, the distribution of different types of deletion was characteristic for tumors from various locations. Large terminal deletions were predominantly seen in RCC and NSCLC (51% and 40%, respectively), correlating with clear cell RCC and squamous cell carcinomas of the lung. In addition to the LUCA region at 3p21.3 (centromeric), we found that the AP20 region (3p21.3, telomeric) was frequently affected in all 4 cancers, suggesting that this newly defined critical region contains multiple TSGs. Moreover, at least 3 candidate cancer-specific loci were identified. The telomeric 3p26.1-p25.3 region was predominantly deleted in RCC and NSCLC. The D3S1286 and D3S3047 markers (3p25.2-p24.3) were deleted nonrandomly in NSCLC. High-frequency LOH was detected in a segment mapped closely distal to the LUCA site (3p21.3), around the D3S2409 and D3S2456 markers.

Abstract
The etiology of RCC is incompletely understood and the inherited genetic contribution uncertain. Although there are rare mendelian forms of RCC stemming from inherited mutations, most cases are thought to be sporadic. We sought to determine the extent of familial aggregation among Icelandic RCC patients in general. Medical and pathologic records for all patients diagnosed with RCC in Iceland between 1955 and 1999 were reviewed. This included a total of 1,078 RCC cases, 660 males and 418 females. With the use of an extensive computerized database containing genealogic information on 630,000 people in Iceland during the past 11 centuries, several analyses were conducted to determine whether the patients were more related to each other than members drawn at random from the population. Patients with RCC were significantly more related to each other than were subjects in matched groups of controls. This relatedness extended beyond the nuclear family. RRs were significantly greater than 1.0 for siblings, parents and cousins of probands. RRs were 2-3 for first-degree relatives and 1.6 for third-degree relatives. The risk of RCC is significantly higher for members of the extended family of an affected individual, as well as the nuclear family. Our results indicate that germline mutations are significantly involved in what has been defined as sporadic RCC.

Abstract
We describe several relatives within one renal cell cancer (RCC) family sharing a constitutional t(2;3) (q35;q21). Based on molecular studies on several independent primary tumors in this family, a causative role for this translocation in tumor development was suggested. Subsequent positional cloning of the 3q21 chromosomal breakpoint revealed that this breakpoint disrupts a novel gene, DIRC2 (disrupted in renal cancer 2). This gene encodes an evolutionary conserved transmembrane protein and represents a novel member of the MFS superfamily of transporters. To evaluate whether DIRC2 is also targeted in sporadic RCC cases with cytogenetically defined 3q21 breakpoints, fluorescence in situ hybridization analysis was performed on metaphase spreads and/or interphase nuclei of 12 primary sporadic RCC using genomic clones from a 3q21 breakpoint-spanning contig as probes. Three breakpoints were mapped proximal to the familial breakpoint and nine breakpoints were mapped distal to this breakpoint. Two of the latter breakpoints were mapped in the contig within 1 Mb distance from the familial breakpoint. Because these clustered 3q21 breakpoints do not coincide with the familial 3q21 breakpoint, they most likely affect genes distinct from DIRC2.

Abstract
Renal-cell carcinoma (RCC) is an important cause of morbidity and mortality, and its incidence has been increasing. Malignant transformation is thought to be associated with changes in the expression of several genes, and this alteration in gene expression is believed to be critical to the development of the malignant phenotype. In this study, the expression of about 60,000 genes/expressed sequence tags in clear-cell RCC, normal kidney, and a set of diseased nonmalignant kidneys was determined with the use of the Affymetrix microarray technique, and differences in gene expression were analyzed. Many genes were found to be differentially expressed in these two sample sets. The genes that were expressed greater than four times more in RCC, those expressed only in RCC, and those expressed greater than two times more in RCC and also expressed in a limited number of other tissues were analyzed for their expression in a variety of other normal and diseased tissues. Some of the genes identified were overexpressed only in RCC among the tissues examined, and some were overexpressed in several other malignant tissues in addition to RCC. Other genes were overexpressed in RCC compared with normal kidney but were also overexpressed in diseased nonmalignant kidney or a variety of other normal tissues. All of the RCC samples could be clustered together, separate from the normal and diseased kidney samples, with the use of the Eisen clustering technique and a set of 50 genes. The observed changes in gene expression in RCC should help further the understanding of the biology of RCC and may be useful in diagnosis, treatment, and imaging.

Abstract
Loss of genetic material from chromosome 3p21.3 is one of the most common and earliest events in the pathogenesis of lung cancer and many other solid tumors. The chromosomal area 3p21.3 is thought to harbor at least one important tumor suppressor gene, which, despite many years of investigation, has remained elusive. In our previous studies, we have identified and cloned a gene from the common homozygous deletion area at 3p21.3. The gene, named RASSF1A (Ras ASSociation domain Family 1A), has homology to a mammalian Ras effector. The RASSF1A gene is epigenetically inactivated in a large percentage of human lung cancers, in particular small cell carcinomas. A high frequency of methylation of RASSF1A is found also in breast cancers, renal cell carcinomas, ovarian, gastric and bladder cancers, and in neuroblastomas. The RASSF1A gene is a candidate for a tumor suppressor gene in 3p21.3.

Abstract
Previously, we described a family with renal cell carcinoma (RCC) and a constitutional balanced t(2;3) (q35;q21). Based on loss of heterozygosity and von Hippel-Lindau (VHL) gene mutation analyses in five tumor biopsies from three patients in this family, we proposed a multistep model for RCC development in which the familial translocation may act as a primary oncogenic event leading to (nondisjunctional) loss of the translocation-derived chromosome 3, and somatic mutation of the VHL gene as a secondary event related to tumor progression. Here, we describe the cytogenetic and molecular analysis of three novel tumors at early stages of development in two members of this family. Again, loss of derivative chromosome 3 was found in two of these tumors and a VHL mutation in one of them. In the third tumor, however, none of these abnormalities could be detected. These results underline our previous notion that loss of derivative chromosome 3 and VHL gene mutation play critical roles in familial RCC. In addition, they show that both anomalies may occur at relatively early stages of tumor development.

Abstract
Clear cell renal cell carcinomas (RCCs) are characterized by a deletion of chromosome 3p, which might result in the inactivation of the FHIT (fragile histidine triad) gene, a putative tumour suppressor gene. To explore the relevance of FHIT aberrations for tumour progression and prognosis in clear cell RCCs, FHIT protein expression was analysed in formalin-fixed tissue from 149 clear cell RCCs by immunohistochemistry. FHIT protein expression was found to be markedly reduced in all RCCs, when compared with adjacent non-neoplastic tubule epithelia. Although remaining below the FHIT levels of normal tubule epithelia, a significant increase of FHIT expression became evident from well (G1) to poorly (G3) differentiated clear cell RCCs (p=0.0001) and from low (pT1) to advanced (pT3) tumour stages (p=0.001). The log-rank test demonstrated a significant inverse correlation (p=0.0074) between FHIT expression and tumour aggressiveness as indicated by patient survival. Cox regression analysis revealed that FHIT expression is an independent prognostic parameter (p=0.0139) in clear cell RCCs. In conclusion, clear cell RCCs show a marked reduction of FHIT protein expression when compared with their putative cells of origin. In contrast to other tumour types, however, loss of FHIT protein expression is significantly less pronounced in poorly differentiated RCCs or advanced tumour stages. This versatility of FHIT expression during tumour progression suggests a role for reversible mechanisms of FHIT inactivation during the initiation and progression of clear cell RCCs.

Abstract
The etiology and progression of renal carcinomas (RCC) is still poorly understood. RCC have been classified into several pathological entities. The most frequent type, clear cell carcinoma, accounts for about 80% of sporadic RCC and shows several chromosome abnormalities documented both by conventional cytogenetics, loss of eterozygosity (LOH) and replication error (RER) studies. In 10 clear cell type sporadic RCC we evaluated LOH and RER using a set of 10 microsatellite markers covering the chromosome 3p region, which has been suggested for interstitial deletions. Electrophoresis was performed by automated sequencer ABI Prism 377 and data were analyzed with Genescan and Genotyper 2.5 softwares. We revealed allelic loss in 48,7% of informative microsatellites and a single case of RER. We found the highest LOH frequency in 3p25-26 region where maps Von Hippel-Lindau (VHL) oncosuppressor gene. In addition, DNA hypermethylation, an alternative mechanism of VHL gene silencing, was evaluated by methylation-specific PCR. However hypermethylation status was not detected in any of our tumor samples.

Abstract
Comparative genomic hybridization (CGH) has been applied to characterize 61 primary renal cell carcinomas derived histogenetically from the proximal tubulus. The tumor samples comprised 46 clear-cell renal cell carcinomas (ccRCCs) and 15 papillary renal cell carcinomas (pRCCs). Changes in the copy number of entire chromosomes or subregions were detected in 56 tumors (92%). In ccRCCs, losses of chromosome 3 or 3p (63%); 14q (30%); 9 (26%); 1 and 6 or 6q (17% each); 4 and 8 or 8p (15% each); 22 (11%); 2 or 2q and 19 (9% each); 7q, 10, 16, 17p, 18, and Y (7% each); and 5, 11, 13, 15, and 21 (4% each) were detected. Most frequent genomic gains in ccRCC were found on chromosome 5 (63%); 7 (35%); 1 or 1q (33%); 2q (24%); 8 or 8q, 12, and 20 (20% each); 3q (17%); 16 (15%); 19 (13%); 6 and 17 or 17q (11% each); and 4, 10, 11, 21, and Y (9% each). In pRCCs, gains in the copy number of chromosomes 7 and 17 (7/15, each) and 16 and 20 (6/15, each) were frequent. One pRCC showed amplification of subchromosome regions 2q22-->q33, 16q, 17q and the entire X chromosome. In pRCC, losses were less frequently seen than gains. Losses of chromosomes 1, 14, 15, and Y (3/15 each) and 2, 4, 6, and 13 (2/15 each) were observed. In ccRCCs, statistical evaluation revealed significant correlations of chromosomal imbalances with tumor stage and grade, i.e., a gain in copy number of chromosome 5 correlated positively with low tumor grade, whereas a gain of chromosomes 10 and 17 correlated positively with high tumor grade. Furthermore, loss of chromosome 4 correlated positively with high tumor stage.

Abstract
Clear cell-type renal cell carcinomas (clear RCC) are characterized almost universally by loss of heterozygosity on chromosome 3p, which usually involves any combination of three regions: 3p25-p26 (harboring the VHL gene), 3p12-p14.2 (containing the FHIT gene), and 3p21-p22, implying inactivation of the resident tumor-suppressor genes (TSGs). For the 3p21-p22 region, the affected TSGs remain, at present, unknown. Recently, the RAS association family 1 gene (isoform RASSF1A), located at 3p21.3, has been identified as a candidate lung and breast TSG. In this report, we demonstrate aberrant silencing by hypermethylation of RASSF1A in both VHL-caused clear RCC tumors and clear RCC without VHL inactivation. We found hypermethylation of RASSF1A's GC-rich putative promoter region in most of analyzed samples, including 39 of 43 primary tumors (91%). The promoter was methylated partially or completely in all 18 RCC cell lines analyzed. Methylation of the GC-rich putative RASSF1A promoter region and loss of transcription of the corresponding mRNA were related causally. RASSF1A expression was reactivated after treatment with 5-aza-2'-deoxycytidine. Forced expression of RASSF1A transcripts in KRC/Y, a renal carcinoma cell line containing a normal and expressed VHL gene, suppressed growth on plastic dishes and anchorage-independent colony formation in soft agar. Mutant RASSF1A had reduced growth suppression activity significantly. These data suggest that RASSF1A is the candidate renal TSG gene for the 3p21.3 region.

Abstract
We identified a novel familial case of clear-cell renal cancer and a t(3;6)(q12;q15). Subsequent cytogenetic and molecular analyses showed the presence of several abnormalities within tumour samples obtained from different patients. Loss of the der(3) chromosome was noted in some, but not all, of the samples. A concomitant VHL gene mutation was found in one of the samples. In addition, cytogenetic and molecular evidence for heterogeneity was obtained through analysis of several biopsy samples from one of the tumours. Based on these results and those reported in the literature, we conclude that loss of der(3) and subsequent VHL gene mutation may represent critical steps in the development of renal cell cancers in persons carrying the chromosome 3 translocation. Moreover, preliminary data suggest that other (epi)genetic changes may be related to tumour initiation.

Abstract
The expression patterns of 7075 genes were analyzed in four conventional (clear cell) renal cell carcinomas (RCC), one chromophobe RCC, and two oncocytomas using cDNA microarrays. Expression profiles were compared among tumors using various clustering algorithms, thereby separating the tumors into two categories consistent with corresponding histopathological diagnoses. Specifically, conventional RCCs were distinguished from chromophobe RCC/oncocytomas based on large-scale gene expression patterns. Chromophobe RCC/oncocytomas displayed similar expression profiles, including genes involved with oxidative phosphorylation and genes expressed normally by distal nephron, consistent with the mitochondrion-rich morphology of these tumors and the theory that both lesions are related histogenetically to distal nephron epithelium. Conventional RCCs underexpressed mitochondrial and distal nephron genes, and were further distinguished from chromophobe RCC/oncocytomas by overexpression of vimentin and class II major histocompatibility complex-related molecules. Novel, tumor-specific expression of four genes-vimentin, class II major histocompatibility complex-associated invariant chain (CD74), parvalbumin, and galectin-3-was confirmed in an independent tumor series by immunohistochemistry. Vimentin was a sensitive, specific marker for conventional RCCs, and parvalbumin was detected primarily in chromophobe RCC/oncocytomas. In conclusion, histopathological subtypes of renal epithelial neoplasia were characterized by distinct patterns of gene expression. Expression patterns were useful for identifying novel molecular markers with potential diagnostic utility.

Abstract
By passaging microcell hybrids (MCHs) containing human chromosome 3 (chr3) on A9 mouse fibrosarcoma background through severe combined immunodeficient (SCID) mice (elimination test), we have previously defined a 1-Mb-long common eliminated region 1 (CER1) at 3p21.3, a second eliminated region (ER2) at 3p21.1-p14 and a common retained region (CRR) at 3q26-qter. In the present work, chr3 was transferred by microcell fusion into the human nonpapillary renal cell carcinoma line KH39 that contained uniparentally disomic chr3. Four MCHs were generated. Compared with KH39, they developed fewer and smaller tumors, which grew after longer latency periods in SCID mice. The tumors were analyzed in comparison with corresponding MCHs by chr3 arm-specific painting, 19 fluorescent in situ hybridization (FISH) probes, and 27 polymorphic markers. Three MCHs that maintained the intact exogenous chr3 in vitro lost one 3p copy in all 11 tumors. Seven of 11 tumors lost the exogenous 3p, whereas four tumors contained mixed cell populations that lacked either the exogenous or one endogenous KH39 derived 3p. In one MCH the exogenous chr3 showed deletions within CER1 and ER2 already in vitro. It remained essentially unchanged in 8/9 derived tumors. The third, exogenous copy of the 3q26-q27 region (part of CRR) was retained in 16/20 tumors. It can be concluded that the human/human MCH-based elimination test identifies similar eliminated and retained regions on chr3 as the human/murine MCH-based test.

Abstract
ADAM-TS/metallospondin genes encode a new family of proteins with structural homology to the ADAM metalloprotease-disintegrin family. However, unlike other ADAMs, these proteins contain thrombospondin type 1 (TSP1) repeats at the carboxy-terminal end and are secreted proteins instead of being membrane bound. Members of the ADAM-TS family have been implicated in the cleavage of proteoglycans, the control of organ shape during development, and the inhibition of angiogenesis. We have cloned a new member of the ADAM-TS/metallospondin family designated here as ADAMTS9. This protein has a metalloprotease domain, a disintegrin-like domain, one internal TSP1 motif, and three carboxy-terminal TSP1-like submotifs. In contrast to other ADAM-TS family members, ADAMTS9 is expressed in all fetal tissues examined as well as some adult tissues. Using FISH and radiation hybrid analysis, we have localized ADAMTS9 to chromosome 3p14.2-p14.3, an area known to be lost in hereditary renal tumors.

Abstract
The UBE1L gene isolated from the chromosome 3p21 region has an extremely reduced level of mRNA in lung cancer. Sequence analysis showed a 45% homology to the human ubiquitin-activating enzyme E1 at the amino acid level. To further characterize the protein product, we generated UBE1L protein-specific antibodies. Immunoblot analysis revealed a full-length gene product of approximately 112 kDa. Assessment of the level and distribution pattern of the UBE1L protein in normal and tumor tissue using the generated antibodies showed that the UBE1L protein was present in normal lung cells and non-lung cancer cell lines, but was undetectable in all 14 human lung cancer cell lines analyzed. This difference in expression of the UBE1L protein between normal lung tissue and lung tumor-derived cell lines suggests a possible involvement of an E1-like protein in the origin and/or progression of lung tumors.

Abstract
We have recently developed an allele titration assay (ATA) to assess the sensitivity and influence of normal cell admixture in loss of heterozygosity (LOH) studies based on CA-repeat. The assay showed that these studies are biased by the size-dependent differential sensitivity of allele detection. Based on these data, we have set up new criteria for evaluation of LOH. By combining these new rules with comparative genome hybridization (CGH) we have shown the presence of interstitial deletions in renal cell carcinoma (RCC) biopsies and cell lines. At least three out of 11 analysed RCC cell lines and three out of 37 biopsies contain interstitial deletions on chromosome 3. Our study suggests the presence of several regions on human chromosome 3 that might contribute to tumor development by their loss: (i) 3p25-p26, around the VHL gene (D3S1317); (ii) 3p21. 3-p22 (between D3S1260 and D3S1611); (iii) 3p21.2 (around D3S1235 and D3S1289); (iv) 3p13-p14 (around D3S1312 and D3S1285). For the first time, AP20 region (3p21.3-p22) was carefully tested for LOH in RCC. It was found that the AP20 region is the most frequently affected area. Our data also suggest that another tumor suppressor gene is located near the VHL gene in 3p25-p26.

Abstract
A variety of human cancers, including renal cell carcinoma (RCC), show frequent heterozygous deletion events in 3p21.3. An approximate 400-kb segment from within 3p21.3 is suspect of harboring a tumor suppressor gene, as it is homozygously deleted in three lung cancer cell lines and heterozygously deleted in virtually all lung tumors. Loss of heterozygosity (LOH) studies of this segment are hampered by the absence of highly informative markers. We have identified several new nucleotide repeats that map within this region, and have used these to complement our previous LOH studies in RCC. Our present analysis clearly shows that the common region of homozygous deletions in the lung cancer cell lines is always contained within the smallest region of overlap of heterozygous deletions in RCC.

Abstract
Normal tissue contamination of tumors may eclipse the detection of loss of heterozygosity (LOH) by microsatellite analysis and may also hamper isolation of tumor suppressor genes. To test the potential impact of this problem, we prepared artificial mixtures of mouse-human microcell hybrid lines that carried different alleles of the same chromosome 3 marker. After performing an allele titration assay, we found a consistent difference between the LOH of a high molecular weight (H) allele and the LOH of a low molecular weight (L) allele of the same CA repeat marker. It follows that normal tissue admixtures will be less of a problem when LOH affects a H allele than with a L allele. Random screening of 100 papers published between 1994 and 1999 revealed that the loss of a L allele was recorded at about half the frequency (52%) of loss of a H allele. To avoid this bias, we have developed rules for the evaluation of LOH data. We suggest that the loss of a L allele should be given more weight than the loss of a H allele in LOH studies using microsatellite markers.

Abstract
BACKGROUND Alterations of chromosome region 3p14 are observed in numerous human malignancies. Because the pattern of allelic losses suggests the existence of at least one tumor suppressor gene within this region, we established a library of yeast artificial chromosomes (YACs) containing contiguous human 3p14 sequences to permit a search for tumor suppressor loci within the 3p14 region by use of functional complementation. METHODS YACs specific for human chromosome region 3p14 were transduced by spheroplast fusion into cells of the human nonpapillary renal carcinoma cell line RCC-1, which shows a cytogenetically detectable 3p deletion and is tumorigenic in nude mice. RESULTS We identified a 3p14.2-specific YAC clone, located in the vicinity of the fragile histidine triad (FHIT) gene (but toward the telomere), that is capable of inducing sustained suppression of tumorigenicity in nude mice and of activating cellular senescence in vitro. Among 23 mice given injections of RCC-1 cells containing this YAC, 16 (70%) remained tumor free for at least 6 months, whereas tumor formation occurred after a median of 6 weeks in control mice given injections of either RCC-1 parental cells or a revertant cell line (in which the YAC had lost all human sequences) or RCC-1 parental cells containing other, unrelated YACs. Similar results were obtained following microcell-mediated transfer of the entire human chromosome 3. CONCLUSION These data provide strong evidence for the existence of a novel tumor suppressor locus adjacent to the previously identified candidate tumor suppressor gene, FHIT, in 3p14.2. Positional cloning of the novel suppressor element within the 3p14.2-specific YAC and the sequence's molecular and functional characterization should add to the understanding of the pathogenesis of renal cell carcinoma and other human tumors that exhibit 3p14 aberrations.

Abstract
Comparative allelotyping of the short arm of human chromosome 3 (3p) in four types of epithelial carcinomas was performed using an identical set of polymorphic markers. In total, 117 samples of non-papillary renal cell carcinoma (RCC), non-small cell lung carcinoma (NSCLC), carcinoma of uterine cervix (CC), and breast carcinoma (BC) were screened for loss of heterozygosity (LOH) with 10 di-, tri- and tetrameric markers covering nine bands of 3p. High LOH frequencies were detected in at least one locus: RCC (36/43, 84%), BC (20/26, 77%), NSCLC (16/24, 67%), and CC (15/24, 62%). Small interstitial deletions prevailed in BC and CC whereas large continuous and discontinuous deletions were mainly found in RCC and NSCLC. Different epithelial tumors displayed unique LOH profiles with partial overlaps in 3p26.1, 3p21.31, and 3p13. The overlap around D3S2409 (3p21.31) appeared common for RCC, BC and CC.
