Abstract
BACKGROUND Comprehensive next-generation sequencing is widely used for precision oncology and precision prevention approaches. We aimed to determine the yield of actionable gene variants, the capacity to uncover hereditary predisposition and liquid biopsy appropriateness instead of, or in addition to, tumor tissue analysis, in a real-world cohort of cancer patients, who may benefit the most from comprehensive genomic profiling. METHODS Seventy-eight matched germline/tumor tissue/liquid biopsy DNA and RNA samples were profiled using the Hereditary Cancer Panel (germline) and the TruSight Oncology 500 panel (tumor tissue/cfDNA) from 23 patients consecutively enrolled at our center according to at least one of the following criteria: no available therapeutic options; long responding patients potentially fit for other therapies; rare tumor; suspected hereditary cancer; primary cancer with high metastatic potential; tumor of unknown primary origin. Variants were annotated for OncoKB and AMP/ASCO/CAP classification. RESULTS The overall yield of actionable somatic and germline variants was 57% (13/23 patients), and 43.5%, excluding variants previously identified by somatic or germline routine testing. The accuracy of tumor/cfDNA germline-focused analysis was demonstrated by overlapping results of germline testing. Five germline variants in BRCA1, VHL, CHEK1, ATM genes would have been missed without extended genomic profiling. A previously undetected BRAF p.V600E mutation was emblematic of the clinical utility of this approach in a patient with a liver undifferentiated embryonal sarcoma responsive to BRAF/MEK inhibition. CONCLUSIONS Our study confirms the clinical relevance of performing extended parallel tumor DNA and cfDNA testing to broaden therapeutic options, to longitudinally monitor cfDNA during patient treatment, and to uncover possible hereditary predisposition following tumor sequencing in patient care.

Abstract
BACKGROUND Most of large epidemiological studies on melanoma susceptibility have been conducted on fair skinned individuals (US, Australia and Northern Europe), while Southern European populations, characterized by high UV exposure and dark-skinned individuals, are underrepresented. OBJECTIVES We report a comprehensive pooled analysis of established high- and intermediate-penetrance genetic variants and clinical characteristics of Mediterranean melanoma families from the MelaNostrum Consortium. METHODS Pooled epidemiological, clinical and genetic (CDKN2A, CDK4, ACD, BAP1, POT1, TERT, and TERF2IP and MC1R genes) retrospective data of melanoma families, collected within the MelaNostrum Consortium in Greece, Italy and Spain, were analysed. Univariate methods and multivariate logistic regression models were used to evaluate the association of variants with characteristics of families and of affected and unaffected family members. Subgroup analysis was performed for each country. RESULTS We included 839 families (1365 affected members and 2123 unaffected individuals). Pathogenic/likely pathogenic CDKN2A variants were identified in 13.8% of families. The strongest predictors of melanoma were ≥2 multiple primary melanoma cases (OR 8.1; 95% CI 3.3-19.7), >3 affected members (OR 2.6; 95% CI 1.3-5.2) and occurrence of pancreatic cancer (OR 4.8; 95% CI 2.4-9.4) in the family (AUC 0.76, 95% CI 0.71-0.82). We observed low frequency variants in POT1 (3.8%), TERF2IP (2.5%), ACD (0.8%) and BAP1 (0.3%). MC1R common variants (≥2 variants and ≥2 RHC variants) were associated with melanoma risk (OR 1.4; 95% CI 1.0-2.0 and OR 4.3; 95% CI 1.2-14.6, respectively). CONCLUSIONS Variants in known high-penetrance genes explain nearly 20% of melanoma familial aggregation in Mediterranean areas. CDKN2A melanoma predictors were identified with potential clinical relevance for cancer risk assessment.

Abstract
BACKGROUND The incidence of cutaneous melanoma is increasing in Italy, in parallel with the implementation of gene panels. Therefore, a revision of national genetic assessment criteria for hereditary melanoma may be needed. The aim of this study was to identify predictors of susceptibility variants in the largest prospective cohort of Italian high-risk melanoma cases studied to date. MATERIALS AND METHODS From 25 Italian centers, we recruited 1044 family members and germline sequenced 940 cutaneous melanoma index cases through a shared gene panel, which included the following genes: CDKN2A, CDK4, BAP1, POT1, ACD, TERF2IP, MITF and ATM. We assessed detection rate according to familial status, region of origin, number of melanomas and presence and type of non-melanoma tumors. RESULTS The overall detection rate was 9.47% (5.53% analyzing CDKN2A alone), ranging from 5.14% in sporadic multiple melanoma cases (spoMPM) with two cutaneous melanomas to 13.9% in familial cases with at least three affected members. Three or more cutaneous melanomas in spoMPM cases, pancreatic cancer and region of origin predicted germline status [odds ratio (OR) = 3.23, 3.15, 2.43, P < 0.05]. Conversely, age > 60 years was a negative independent predictor (OR = 0.13, P = 0.008), and was the age category with the lowest detection rate, especially for CDKN2A. Detection rate was 19% when cutaneous melanoma and pancreatic cancer clustered together. CONCLUSIONS Gene panel doubled the detection rate given by CDKN2A alone. National genetic testing criteria may need a revision, especially regarding age cut-off (60) in the absence of strong family history, pancreatic cancer and/or a high number of cutaneous melanomas.

Abstract
PURPOSE Ataxia-Telangiectasia Mutated (ATM) has been implicated in the risk of several cancers, but establishing a causal relationship is often challenging. Although ATM single-nucleotide polymorphisms have been linked to melanoma, few functional alleles have been identified. Therefore, ATM impact on melanoma predisposition is unclear. METHODS From 22 American, Australian, and European sites, we collected 2,104 familial, multiple primary (MPM), and sporadic melanoma cases who underwent ATM genotyping via panel, exome, or genome sequencing, and compared the allele frequency (AF) of selected ATM variants classified as loss-of-function (LOF) and variants of uncertain significance (VUS) between this cohort and the gnomAD non-Finnish European (NFE) data set. RESULTS LOF variants were more represented in our study cohort than in gnomAD NFE, both in all (AF = 0.005 and 0.002, OR = 2.6, 95% CI = 1.56-4.11, p < 0.01), and familial + MPM cases (AF = 0.0054 and 0.002, OR = 2.97, p < 0.01). Similarly, VUS were enriched in all (AF = 0.046 and 0.033, OR = 1.41, 95% CI = 1.6-5.09, p < 0.01) and familial + MPM cases (AF = 0.053 and 0.033, OR = 1.63, p < 0.01). In a case-control comparison of two centers that provided 1,446 controls, LOF and VUS were enriched in familial + MPM cases (p = 0.027, p = 0.018). CONCLUSION This study, describing the largest multicenter melanoma cohort investigated for ATM germline variants, supports the role of ATM as a melanoma predisposition gene, with LOF variants suggesting a moderate-risk.

Abstract
BACKGROUND A polygenic inheritance involving high, medium and low penetrance genes has been suggested for melanoma susceptibility in adults, but genetic information is scarce for paediatric patients. OBJECTIVE We aim to analyse the major high and intermediate melanoma risk genes, CDKN2A, CDK4, POT1, MITF and MC1R, in a large multicentre cohort of Italian children and adolescents in order to explore the genetic context of paediatric melanoma and to reveal potential differences in heritability between children and adolescents. METHODS One-hundred-twenty-three patients (<21 years) from nine Italian centres were analysed for the CDKN2A, CDK4, POT1, MITF, and MC1R melanoma predisposing genes. The rate of gene variants was compared between sporadic, familial and multiple melanoma patients and between children and adolescents, and their association with clinico-pathological characteristics was evaluated. RESULTS Most patients carried MC1R variants (67%), while CDKN2A pathogenic variants were found in 9% of the cases, the MITF E318K in 2% of patients and none carried CDK4 or the POT1 S270N pathogenic variant. Sporadic melanoma patients significantly differed from familial and multiple cases for the young age at diagnosis, infrequent red hair colour, low number of nevi, low frequency of CDKN2A pathogenic variants and of the MC1R R160W variant. Melanoma in children (≤12 years) had more frequently spitzoid histotype, were located on the head/neck and upper limbs and had higher Breslow thickness. The MC1R V92M variant was more common in children than in adolescents. CDKN2A common polymorphisms and MC1R variants were associated with a high number of nevi. CONCLUSION Our results confirm the scarce involvement of the major high-risk susceptibility genes in paediatric melanoma and suggest the implication of MC1R gene variants especially in the children population.

Abstract
PURPOSE Gastrointestinal stromal tumors (GISTs) are mesenchymal tumors of the gastrointestinal tract. Most (80 %) contain activating mutations in the KIT receptor tyrosine kinase, roughly 10 % in platelet-derived growth factor receptor-alpha (PDGFRA). In a small subset, BRAF mutations are an alternative molecular pathway. GISTs respond well to imatinib, but low response is seen in patients with wild-type KIT or PDGFRA. Resistance has also been reported as a result of mutations in downstream effectors such as BRAF. METHODS We provide here a molecular characterization of a series of primary GISTs from Italian patients. Of 121 GIST cases diagnosed between 2000 and 2012, 83 were evaluated by PCR amplification and direct sequencing for mutations in KIT exons 8, 9, 11, 13, and 17, PDGFRA exons 12, 14, and 18, and BRAF exon 15. Eighty-one GISTs also underwent K-RAS testing. RESULTS Sixty-four GISTs were positive: 55 had mutations in KIT and 9 in PDGFRA; 16 patients were mutation negative. Three samples came from NF1 patients and were KIT- and PDGFRA negative. Overall, we identified six novel mutations in KIT (p.K550_M552delinsL, p.Q556_W557delinsG p.Q556_G575del, p.W557_V559delinsQ p.P573_R588dup, p.G592_K593dup) and one novel mutation in PDGFRA (p.D842_N848delinsVDV), thus contributing to widening the spectrum of known mutations in GIST tumors and confirming the most frequently altered regions underlying GIST development. CONCLUSIONS Among the 64 KIT- and PDGFRA-positive sporadic patients in our series, no BRAF or KRAS mutations were identified, suggesting that co-occurrence of these mutations is likely to be rare in the northwestern Italian population and not a frequent cause of primary resistance to imatinib in KIT-positive GIST patients.

Abstract
A French and an Australian study have recently identified a rare germline functional variant in the microphthalmia-associated transcription factor (MITF) (E318K) that predisposes to familial and sporadic melanoma and to renal cell carcinoma (RCC), showing a new link between two tumour types with different risk factors and between deregulated sumoylation and cancer. The aim of this study was to test the prevalence of the MITF E318K mutation in 667 Italian melanoma patients. We observed significant associations between histological subtypes and family cancer history. Carriers exhibited a nearly threefold higher risk of developing melanoma compared with controls. Carriers were also more likely to have developed multiple primary melanomas (6.40-fold), compared with wt patients. Carriers with a personal and/or family history of pancreatic cancer and kidney cancer had a nearly 31- and eightfold higher risk of developing melanoma compared with wt patients. Our findings further support MITF as a medium-penetrance melanoma susceptibility gene, highlight a potential association with histological subtypes and suggest that MITF may predispose to pancreatic cancer.

Abstract
Pancreatic adenocarcinoma (PC) is the third most common cancer associated with BRCA mutations. Most notice has been given to BRCA2, while the association between BRCA1 and PC is less widely reported. Recently, PALB2 has been implicated in both PC and breast cancer (BC) susceptibility. We selected 29 Italian PC patients from a case-control study of PC according to their personal and family history of both PC and breast/ovarian cancer (BC/OC) and tested them for presence of germline mutations in BRCA1, BRCA2 and PALB2. We identified no germline mutations or deletions in PALB2, but detected 7 BRCA mutations (4 in BRCA1 and 3 in BRCA2). These findings suggest that PALB2 does not play a major role in PC susceptibility in our population. As we found an almost equal frequency of germline mutations in BRCA1 and BRCA2, germline alterations in either of these genes may explain a subset of Italian families presenting both PC and BC/OC. Moreover, as we began the observation of these families from probands who are affected by PC, we provide here a direct assessment of the role of PALB2 and BRCA mutations in PC susceptibility.

Abstract
Lynch syndrome is an inherited cancer syndrome caused by germline mutations in mismatch repair (MMR) genes MLH1, MSH2, MSH6 and PMS2. LS predisposes to high risk of early-onset colorectal, endometrial and other tumors. Patients with Lynch syndrome have also been shown to have an elevated risk for pancreatic cancer (PC). In this study, we aimed to estimate the frequency of suspected Lynch syndrome among a series of 135 PC patients. Further, we wanted to determine the frequency of MMR gene mutations in the suspected Lynch syndrome cases. We also aimed to verify the pathogenicity of any novel non-truncating variants we might detect with a functional assay. Based on personal and/or familial cancer history, 19 patients were classified as suspected Lynch syndrome cases. DNA material for mutation analysis was available for eleven of them. Four patients were found to carry a total of five MLH1 or MSH2 variants. Of these, MSH2-Q402X, MSH2-G322D, and MLH1-K618A had been previously reported, while the MSH2-E205Q and MSH2-V367I variants were novel. MSH2-Q402X is a known stop mutation and reported here for the first time here in association with PC. MLH1-K618A was found in the unaffected branch of a kindred, suggesting that it may be a polymorphism or a low penetrance variant. MSH2-G322D likely does not cause a MMR defect, although this variant has also been associated with breast cancer as indeed seen in our patient. The novel variants MSH2-E205Q and MSH2-V367I were found in the same patient. Both novel variants were however functional in the applied MMR assay. Our findings suggest that only a small subset of pancreatic cancer patients carry pathogenic MMR mutations.

Abstract
BACKGROUND Breast cancer patients have a cumulative lifetime risk of 2%-15% of developing a contralateral metastatic or ex novo primary cancer. From prognostic and therapeutic viewpoints, it is important to differentiate metastatic from second primary. To distinguish these entities, we investigated whether the pattern of X chromosome inactivation could determine whether the two tumors derived from different progenitor cells. MATERIALS AND METHODS The clonality of bilateral breast cancer was evaluated through the X-inactivation analysis using the human androgen receptor gene (HUMARA) polymorphism and the histopathologic and molecular results were compared. A different or an identical pattern of X inactivation was considered as indicator of a second primary cancer or not informative, respectively. We considered morphological indicators of a new primary cancer the absence of concordance in the histological type or a better histological differentiation. RESULTS Ten patients with bilateral breast cancer were evaluated. Morphological criteria indicated that eight were second primary, a conclusion confirmed by the X-inactivation analysis. Two cases classified as recurrence according to morphological criteria were classified as second tumor by molecular analysis. CONCLUSION Our results show that the HUMARA clonality assay can improve the histological parameters in differentiating metastatic cancer from second primary cancer.

Abstract
Gorlin syndrome (GS) is inherited in an autosomal dominant pattern with high-penetrance and is characterized by a range of developmental anomalies and increased risk of developing basal cell carcinoma and medulloblastoma. Between 50% and 85% of patients with GS harbor germ line mutations in the only susceptibility gene identified to date, PTCH1, a key component in the Sonic Hedgehog signaling pathway. Another component in this pathway, SUFU, is known to be involved in susceptibility to medulloblastoma but has never been reported in GS patients to date. We have identified the known c.1022 + 1G>A SUFU germ line splicing mutation in a family that was PTCH1-negative and who had signs and symptoms of GS, including medulloblastoma. This is the first report of a germ line SUFU mutation associated with GS.

Abstract
INTRODUCTION Calcitonin measurement is advised in the diagnosis of thyroid nodules, as it is an accurate marker of medullary thyroid carcinoma (MTC). C-cell hyperplasia (CCH)-induced hypercalcitoninemia cannot be distinguished from that induced by MTC, unless surgery is performed. CASE We report the clinical and biological features of a patient with a family history of cancer, including melanoma and pancreatic cancer, who had previously undergone surgery for melanoma. He presented the unusual association of papillary thyroid carcinoma (PTC), normocalcemic hyperparathyroidism, and hypercalcitoninemia with a pathological response to pentagastrin, which was histologically deemed secondary to CCH. Multiple endocrine neoplasia (MEN) 2A was diagnosed. RET gene analysis showed a p.V804M missense mutation in exon 14, a low- but variably penetrant defect found in both sporadic and MEN2A-associated MTC/CCH, and a p.G691S polymorphism in exon 11. Furthermore, the germline P48T mutation was found in the CDKN2A gene exon 1, which is known to be associated with melanoma and pancreatic cancer. The patient showed the uncommon coexistence of a germline mutation in two suppressor genes, RET and CDKN2A; this finding, deemed to be a mere coincidence, did not modify the phenotype expected by each single mutation. CCH associated with V804M RET mutation is a precancerous condition and surgery is recommended. In order to exclude MTC, surgery is advised in patients with a pathological calcitonin response to pentagastrin, in the absence of thyroid autoimmunity. CCH-induced hypercalcitoninemia can be associated with thyroid cancers other than MTC (e.g., PTC). Family history is important in scheduling specific genetic screening in high-risk patients and their relatives.

Abstract
10543 Background: Mutations in the CDKN2A gene underlie melanoma susceptibility in as many as 50% of melanoma kindreds in selected populations, and several CDKN2A founder mutations have been described. Inherited mutations in CDKN2A have been found to be associated with other non-melanoma cancers including pancreatic cancer and neural system tumours. Here we report a novel germline mutation in exon 1 of the CDKN2A gene, E27X, which we first detected in melanoma patients living in or originally from a small geographic area bordering Liguria, in north-western Italy. A subset of melanoma kindreds positive for this mutation displayed pancreatic cancer and neuroblastoma. Methods: We investigated 70 pancreatic cancer patients from a case-control study living in or originally coming from a small geographic area bordering Liguria, in north-western Italy, for CDKN2A mutations and ARF. Results: 2 out of 70 patients displayed the E27X mutation and 1 of the 2 patients had a first degree relative affected by pancreatic cancer. Conclusions: E27X generates a premature stop codon, leading to dramatically reduced protein levels of p16 and leaving p14ARF unaltered. As pancreatic cancer and neural system tumours have been postulated to be preferentially associated with CDKN2A mutations located in exon 2 and/or affecting p14ARF alone, the position of E27X in exon 1a provides interesting insights towards clarifying the mechanisms by which the CDKN2A/ARF locus is involved in cancer predisposition. Its finding in pancreatic cancer patients confirms common susceptibility to melanoma and pancreatic cancer due to this CDKN2A exon 1 mutation. No significant financial relationships to disclose.

Abstract
BACKGROUND Roughly 40% of germinal mutations in melanoma families (MF) affect p16(INK4a) and p14(ARF). We investigated the association between INK4/ARF alterations and the occurrence of pancreatic cancer in MF and in sporadic pancreatic cancer (SPC) patients. PATIENTS AND METHODS Forty-nine MF, 66 SPC cases and 54 controls were enrolled. The INK4/ARF locus was screened. RESULTS As compared with the general population, the risk of pancreatic cancer (PC) was increased 9.4-fold [95% confidence interval (CI) 2.7-33.4] and 2.2-fold (95% CI 0.8-5.7) in G101W-positive and -negative MF, respectively, while mean ages at onset were 61 and 77 years, respectively. A 1.7 (95% CI 1.06-2.79) increased risk of cancer at any site was observed among first-degree relatives of SPC cases as compared with controls. The G101W founder mutation was detected in 4% of SPC cases but the rate increased to 13% when tumor clustering in either branch of families was taken into account. One G101W-positive PC patient with a melanoma in a first-degree relative harbored a germline deletion of the second allele, including exon 1B. CONCLUSIONS The presence of a deletion including exon 1B in two PC patients points to the involvement of p14(ARF) in the development of PC and may suggest that the increased risk of PC in MF is caused by impairment of both loci.

Abstract
BACKGROUND Leflunomide and its active metabolite A77 1726 reversibly inhibits the enzyme dihydro-orotate dehydrogenase, the rate limiting step in de novo synthesis of pyrimidines and progression of the cell cycle in different cell lines, mainly activated T lymphocytes. OBJECTIVE To analyse in vitro the possible anti-inflammatory effects exerted by A77 1726, on cultured macrophages, obtained from the synovial tissues of patients with rheumatoid arthritis (RA). METHODS The effects of different doses of A77 1726 on intracytoplasmic expression and extracellular concentration of inflammatory cytokines (tumour necrosis factor alpha (TNFalpha), interleukin (IL) 1beta, IL6), as well as the influence on production and expression of intercellular adhesion molecule-1 (ICAM-1) and cyclo-oxygenase 2 (COX-2) by primary cultures of synovial macrophages from patients with RA, were evaluated by immunocytochemistry and western blot analysis. The observations were made at four and 24 hours. RESULTS A progressive and significant time and dose dependent decrease of the number of positive macrophages for intracellular TNFalpha and IL1beta, treated with different doses of A77 1726, was found in comparison with untreated cells. The extracellular concentration of TNFalpha was found to be significantly decreased in media containing cultured macrophages at 24 hours for all tested doses of A77 1726. At 24 hours, a significant time and dose dependent decrease of ICAM-1 and COX-2 expression by cultured macrophages after A77 1726 treatment was found. CONCLUSIONS In conclusion, the mechanism of antiproliferative activity exerted by leflunomide on activated T lymphocytes seems to be the same mechanism (alteration of the cell cycle progression) which interferes with the functions of other activated cells-namely, the monocytes/macrophages, which are strongly involved in the inflammatory reaction in RA synovial tissue. The positive clinical results seem to confirm that leflunomide exerts an anti-inflammatory action on phagocytic cells in short and long term treatment of RA.

Abstract
Germline mutations of CDKN2A, at 9p21, are responsible for predisposition to melanoma in some families. However, evidence of linkage to 9p21 has been demonstrated in a significant proportion of kindreds with no detectable mutations in CDKN2A. It is possible that mutations in noncoding regions may be responsible for predisposition to melanoma in these families. We have analyzed approximately 1 kb of the CDKN2A promoter upstream of the start codon in an attempt to identify causal mutations in 107 melanoma families. Four sequence variants were detected. Two of these (A-191G and A-493T) did not segregate with disease and were present in a control population at a comparable frequency, indicating that they are unlikely to predispose to melanoma. The A-493T variant appeared to be in linkage disequilibrium with the previously described CDKN2A polymorphism Ala148Thr. The variant G-735A was detected in the control population, but segregation of this variant with melanoma within families could not be discounted. The fourth variant (G-34T), located in the 5' UTR, creates an aberrant initiation codon. This variant appeared to segregate with melanoma and was not detected in a control population. G-34T has recently been identified in a subset of Canadian melanoma families and was concluded to be associated with predisposition to melanoma. The creation of an aberrant initiation site in the 5' UTR may have an important role in carcinogenesis in a small percentage of families; however, mutations in the CDKN2A promoter appear to have a limited role in predisposition to melanoma.

Abstract
Germline mutations impairing the p16(INK4)-function have previously been demonstrated to be responsible for genetic predisposition in at least one half of melanoma-prone kindreds of North European origin. Familial melanoma kindreds have also been found to present an increased risk of pancreatic cancer and other cancers, but results relative to more common neoplasias incidence, in particular, are heterogeneous. We report here a clinical-epidemiological study, including the presence of additional neoplasias, in 14 apparently unrelated kindreds coming from a small geographic region of Northern Italy (Liguria), having therefore lived for generations in similar environmental conditions. We identified the common p16 missense mutation (Gly101Trp) reported in several previously studied kindreds, in 7 of 14 families, whereas the remaining 7 families had no detectable mutations in the coding region of p16 gene. Median age at diagnosis and other melanoma features were studied. When compared with the expected figures, based on regional incidence rates, a significant excess of pancreatic cancer, with 4 cases diagnosed, and of breast cancer, with 7 cases, was observed. The 7 families without apparent CDKN2A involvement were also negative for hot-spot exon 2 mutation of CDK4. Environmental factors do not appear to play a role in the excess of non-melanoma neoplasia in our families, as somewhat substantiated by the control group, composed of spouses and members of non-affected branches; they do not reveal any increased cancer incidence compared with the general population. Furthermore, given the proven significance of interaction between the melanoma susceptibility gene and the propensity to sunburns and other environmental risk factors, our results, obtained from a small but homogeneous sample, may have important implications for further risk assessment studies.

Abstract
To further clarify the complex transcriptional regulation of the human GM-CSF gene, which was extensively investigated in activated T cells, we have studied the role of an upstream NF-kappaB like site in the 5637 non-lymphoid cell line, which derives from a bladder carcinoma and constitutively produces GM-CSF. This sequence, named the A element, has an active role on GM-CSF transcription and is responsive to the tumor promoter PMA in transient transfection experiments. We describe here a heterodimeric binding complex of NF-kappaB subunits (c-Rel and p65) which is identical to the one obtained using the HIV-LTR-kappaB site as recognition sequence and different from the one (c-Rel and p50) observed with nuclear extracts from Mo T-lymphoid HTLV-II infected cells.

Abstract
To further extend the previous analysis of cis-acting elements and cognate trans-acting factors that contribute to GM-CSF transcriptional regulations, we have examined a promoter region between -1742 and -2010. DNase I footprinting assays showed four protected sequences named A, B, C and D. DNA transfections in the T-lymphoid Mo cell line, which constitutively expresses GM-CSF, indicated that the A element, located between -2002 and -1984, has a positive role on transcription. Further characterization by electrophoretic mobility shift assays in the presence of different competitor oligonucleotides showed that this element binds a factor of the NF-kappa B/Rel family.

Abstract
A human melanoma cell line, MEL-P, expressing granulocyte-macrophage colony-stimulating factor (GM-CSF) and its specific receptor was newly established from a primary nodular lesion of a patient with a particularly unfavourable prognosis. Cytogenetic, immunophenotypic, cytokine and intercellular adhesion molecule (ICAM)-1 production analyses confirmed that this cell line was similar to the fresh melanoma cells from which it had been established. MEL-P constitutes a valuable model for the study of multistep tumour progression and the role of biologically active GM-CSF production in human malignant melanoma. Our results show a decreasing expression of HLA class I molecules during in vitro culture, when GM-CSF secretion attains the highest levels, and a constantly high production of ICAM-1. The inhibitory effect of GM-CSF antisense treatment on cellular growth might suggest the presence of an autocrine mechanism. On the whole, these data are consistent with the possible involvement of high GM-CSF production in the metastatic competence of melanoma cells through the autocrine mechanism of growth and/or the activation of other migration-related molecules by its local production in metastatic invasion.
