Abstract
BACKGROUND Polygenic risk scores (PRSs) have been used to stratify colorectal cancer (CRC) risk in the general population, whereas its role in Lynch syndrome (LS), the most common type of hereditary CRC, is still conflicting. We aimed to assess the ability of PRS to refine CRC risk prediction in European-descendant individuals with LS. METHODS 1465 individuals with LS (557 MLH1, 517 MSH2/EPCAM, 299 MSH6 and 92 PMS2) and 5656 CRC-free population-based controls from two independent cohorts were included. A 91-SNP PRS was applied. A Cox proportional hazard regression model with 'family' as a random effect and a logistic regression analysis, followed by a meta-analysis combining both cohorts were conducted. RESULTS Overall, we did not observe a statistically significant association between PRS and CRC risk in the entire cohort. Nevertheless, PRS was significantly associated with a slightly increased risk of CRC or advanced adenoma (AA), in those with CRC diagnosed <50 years and in individuals with multiple CRCs or AAs diagnosed <60 years. CONCLUSION The PRS may slightly influence CRC risk in individuals with LS in particular in more extreme phenotypes such as early-onset disease. However, the study design and recruitment strategy strongly influence the results of PRS studies. A separate analysis by genes and its combination with other genetic and non-genetic risk factors will help refine its role as a risk modifier in LS.

Abstract
BACKGROUND Patients with serrated polyposis syndrome (SPS) have multiple and/or large serrated colonic polyps and higher risk for colorectal cancer. SPS inherited genetic basis is mostly unknown. We aimed to identify new germline predisposition factors for SPS by functionally evaluating a candidate gene and replicating it in additional SPS cohorts. METHODS After a previous whole-exome sequencing in 39 SPS patients from 16 families (discovery cohort), we sequenced specific genes in an independent validation cohort of 211 unrelated SPS cases. Additional external replication was also available in 297 SPS cases. The WNK2 gene was disrupted in HT-29 cells by gene editing, and WNK2 variants were transfected using a lentiviral delivery system. Cells were analysed by immunoblots, real-time PCR and functional assays monitoring the mitogen-activated protein kinase (MAPK) pathway, cell cycle progression, survival and adhesion. RESULTS We identified 2 rare germline variants in the WNK2 gene in the discovery cohort, 3 additional variants in the validation cohort and 10 other variants in the external cohorts. Variants c.2105C>T (p.Pro702Leu), c.4820C>T (p.Ala1607Val) and c.6157G>A (p.Val2053Ile) were functionally characterised, displaying higher levels of phospho-PAK1/2, phospho-ERK1/2, CCND1, clonogenic capacity and MMP2. CONCLUSION After whole-exome sequencing in SPS cases with familial aggregation and replication of results in additional cohorts, we identified rare germline variants in the WNK2 gene. Functional studies suggested germline WNK2 variants affect protein function in the context of the MAPK pathway, a molecular hallmark in this disease.

Abstract
Screenwide is a case-control study (2017−2021) including women with incident endometrial and ovarian cancers (EC and OC), BRCA1/2 and MMR pathogenic variant carriers, and age-matched controls from three centers in Spain. Participants completed a personal interview on their sociodemographic factors, occupational exposure, medication, lifestyle, and medical history. We collected biological specimens, including blood samples, self-collected vaginal specimens, cervical pap-brush samples, uterine specimens, and, when available, tumor samples. The planned analyses included evaluation of the potential risk factors for EC/OC; evaluation of molecular biomarkers in minimally invasive samples; evaluation of the cost-effectiveness of molecular tests; and the generation of predictive scores to integrate different epidemiologic, clinical, and molecular factors. Overall, 182 EC, 69 OC, 98 BRCA pathogenic variant carriers, 104 MMR pathogenic variant carriers, and 385 controls were enrolled. The overall participation rate was 85.7%. The pilot study using 61 samples from nine EC cases and four controls showed that genetic variants at the variant allele fraction > 5% found in tumors (n = 61 variants across the nine tumors) were detected in paired endometrial aspirates, clinician-collected cervical samples, and vaginal self-samples with detection rates of 90% (55/61), 79% (48/61), and 72% (44/61) by duplex sequencing, respectively. Among the controls, only one somatic mutation was detected in a cervical sample. We enrolled more than 800 women to evaluate new early detection strategies. The preliminary data suggest that our methodological approach could be useful for the early detection of gynecological cancers.

Abstract
Oncogenic mutations of KRAS are found in the most aggressive human tumors, including colorectal cancer. It has been suggested that oncogenic KRAS phosphorylation at Ser181 modulates its activity and favors cell transformation. Using nonphosphorylatable (S181A), phosphomimetic (S181D), and phospho-/dephosphorylatable (S181) oncogenic KRAS mutants, we analyzed the role of this phosphorylation to the maintenance of tumorigenic properties of colorectal cancer cells. Our data show that the presence of phospho-/dephosphorylatable oncogenic KRAS is required for preserving the epithelial organization of colorectal cancer cells in 3D cultures, and for supporting subcutaneous tumor growth in mice. Interestingly, gene expression differed according to the phosphorylation status of KRAS. In DLD-1 cells, CTNNA1 was only expressed in phospho-/dephosphorylatable oncogenic KRAS-expressing cells, correlating with cell polarization. Moreover, lack of oncogenic KRAS phosphorylation leads to changes in expression of genes related to cell invasion, such as SERPINE1, PRSS1,2,3, and NEO1, and expression of phosphomimetic oncogenic KRAS resulted in diminished expression of genes involved in enterocyte differentiation, such as HNF4G. Finally, the analysis, in a public data set of human colorectal cancer, of the gene expression signatures associated with phosphomimetic and nonphosphorylatable oncogenic KRAS suggests that this post-translational modification regulates tumor progression in patients.

Abstract
Tumor targeting and intratumoral virus spreading are key features for successful oncolytic virotherapy. VCN-11 is a novel oncolytic adenovirus, genetically modified to express hyaluronidase (PH20) and display an albumin-binding domain (ABD) on the hexon. ABD allows the virus to self-coat with albumin when entering the bloodstream and evade neutralizing antibodies (NAbs). Here, we validate VCN-11 mechanism of action and characterize its toxicity. VCN-11 replication, hyaluronidase activity and binding to human albumin to evade NAbs was evaluated. Toxicity and efficacy of VCN-11 were assessed in mice and hamsters. Tumor targeting, and antitumor activity was analyzed in the presence of NAbs in several tumor models. VCN-11 induced 450 times more cytotoxicity in tumor cells than in normal cells. VCN-11 hyaluronidase production was confirmed by measuring PH20 activity in vitro and in virus-infected tumor areas in vivo. VCN-11 evaded NAbs from different sources and tumor targeting was demonstrated in the presence of high levels of NAbs in vivo, whereas the control virus without ABD was neutralized. VCN-11 showed a low toxicity profile in athymic nude mice and Syrian hamsters, allowing treatments with high doses and fractionated administrations without major toxicities (up to 1.2x1011vp/mouse and 7.5x1011vp/hamster). Fractionated intravenous administrations improved circulation kinetics and tumor targeting. VCN-11 antitumor efficacy was demonstrated in the presence of NAbs against Ad5 and itself. Oncolytic adenovirus VCN-11 disrupts tumor matrix and displays antitumor effects even in the presence of NAbs. These features make VCN-11 a safe promising candidate to test re-administration in clinical trials.

Abstract
CONTEXT Lynch syndrome (LS) is the most common inherited colorectal and endometrial cancer syndrome, caused by germline mutations in DNA mismatch repair (MMR) genes. It is also characterized by an increased risk of other tumors with lower prevalence, such as adrenal cortical carcinoma (ACC), an endocrine tumor with an incidence of <2 cases/million individuals/year. Most ACC developed during childhood are associated with hereditary syndromes. In adults, this association is not as well established as in children. Previous studies showed a 3.2% prevalence of LS among patients with ACC. EVIDENCE ACQUISITION The objective of this study is to determine the prevalence of ACC in a Spanish LS cohort and their molecular and histological characteristics. This retrospective study includes 634 patients from 220 LS families registered between 1999 and 2018. EVIDENCE SYNTHESIS During the follow-up period, 3 patients were diagnosed with ACC (0.47%); all were carriers of a MSH2 germline mutation. The 3 ACC patients presented loss of expression of MSH2 and MSH6 proteins. One tumor analysis showed loss of heterozygosity of the MSH2 wildtype allele. Our findings support previous data that considered ACC as a LS spectrum tumor. CONCLUSION MMR protein immunohistochemistry screening could be an efficient strategy to detect LS in patients with ACC.

Abstract
INTRODUCTION Germline CNVs are important contributors to hereditary cancer. In genetic diagnostics, multiplex ligation-dependent probe amplification (MLPA) is commonly used to identify them. However, MLPA is time-consuming and expensive if applied to many genes, hence many routine laboratories test only a subset of genes of interest. METHODS AND RESULTS We evaluated a next-generation sequencing (NGS)-based CNV detection tool (DECoN) as first-tier screening to decrease costs and turnaround time and expand CNV analysis to all genes of clinical interest in our diagnostics routine. We used DECoN in a retrospective cohort of 1860 patients where a limited number of genes were previously analysed by MLPA, and in a prospective cohort of 2041 patients, without MLPA analysis. In the retrospective cohort, 6 new CNVs were identified and confirmed by MLPA. In the prospective cohort, 19 CNVs were identified and confirmed by MLPA, 8 of these would have been lost in our previous MLPA-restricted detection strategy. Also, the number of genes tested by MLPA across all samples decreased by 93.0% in the prospective cohort. CONCLUSION Including an in silico germline NGS CNV detection tool improved our genetic diagnostics strategy in hereditary cancer, both increasing the number of CNVs detected and reducing turnaround time and costs.

Abstract
INTRODUCTION Actionable somatic molecular alterations are found in 15% to 20% of NSCLC in Europe. NSCLC is a tumor observed in patients with germline TP53 variants causing Li-Fraumeni syndrome (LFS), but its somatic molecular profile is unknown. METHODS Retrospective study of clinical and molecular profiles of patients with NSCLC and germline TP53 variants. RESULTS Among 22 patients with NSCLC and LFS (n = 23 lung tumors), 64% were women, median age was 51 years, 84% were nonsmokers, 73% had adenocarcinoma histological subtype, and 84% were diagnosed with advanced-stage disease. These patients harbored 16 distinct germline TP53 variants; the most common was p.R158H (5/22; three in the same family). Personal and family histories of cancer were reported in 71% and 90% of patients, respectively. In most cases (87%, 13/15), lung cancer was diagnosed with a late onset. Of the 21 tumors analyzed, somatic oncogenic driver mutations were found in 19 of 21 (90%), EGFR mutations in 18 (exon 19 deletion in 12 cases, L858R in three cases, and G719A, exon 20 insertion, and missing mutation subtype, each with one case), and ROS1 fusion in one case. A PI3KCA mutation was concurrently detected at diagnosis in three EGFR exon 19-deleted tumors (3/12). The median overall survival was 37.3 months in 14 patients treated with EGFR inhibitors; seven developed resistance, five (71%) acquired EGFR-T790M mutation, and one had SCLC transformation. CONCLUSIONS Driver oncogenic alterations were observed in 90% of the LFS tumors, mainly EGFR mutations; one ROS1 fusion was also observed. The germline TP53 variants and lung cancer carcinogenesis driven by oncogenic processes need further evaluation.

Abstract
Background Serrated polyposis syndrome (SPS) is a clinical entity characterised by large and/ormultiple serrated polyps throughout the colon and increased risk for colorectal cancer (CRC). The basis for SPS genetic predisposition is largely unknown. Common, low-penetrance genetic variants have been consistently associated with CRC susceptibility, however, their role in SPS genetic predisposition has not been yet explored. Objective The aim of this study was to evaluate if common, low-penetrance genetic variants for CRC risk are also implicated in SPS genetic susceptibility. Methods A case-control study was performed in 219 SPS patients and 548 asymptomatic controls analysing 65 CRC susceptibility variants. A risk prediction model for SPS predisposition was developed. Results Statistically significant associations with SPS were found for seven genetic variants (rs4779584-GREM1, rs16892766-EIF3H, rs3217810-CCND2, rs992157-PNKD1/TMBIM1, rs704017-ZMIZ1, rs11196172-TCF7L2, rs6061231-LAMA5). The GREM1 risk allele was remarkably over-represented in SPS cases compared with controls (OR=1.573, 1.21–2.04, p value=0.0006). A fourfold increase in SPS risk was observed when comparing subjects within the highest decile of variants (≥65) with those in the first decile (≤50). Conclusions Genetic variants for CRC risk are also involved in SPS susceptibility, being the most relevant ones rs4779584-GREM1, rs16892766-EIF3H and rs3217810-CCND2.

Abstract
Due to the anatomical continuity of the uterine cavity with the cervix, genomic exploitation of material from routine Pap smears and other noninvasive sampling methods represent a unique opportunity to detect signs of disease using biological material shed from the upper genital tract. Recent research findings offer a promising perspective in the detection of endometrial cancer, but certain questions need to be addressed in order to accelerate the implementation of novel technologies in a routine screening or clinical setting. We discuss here new perspectives on detection of endometrial cancer using genomic and other biomarkers in minimally invasive sampling methods with a special focus on public health classic screening criteria, highlighting current gaps in knowledge.

Abstract
INTRODUCTION The current availability of genomic information represents an opportunity to develop new strategies for early detection of cancer. New molecular tests for endometrial cancer may improve performance and failure rates of histological aspirate-based diagnosis, and provide promising perspectives for a potential screening scenario. However, the selection of relevant biomarkers to develop efficient strategies can be a challenge. MATERIALS AND METHODS We developed an algorithm to identify the largest number of patients with endometrial cancer using the minimum number of somatic mutations based on The Cancer Genome Atlas (TCGA) dataset. RESULTS The algorithm provided the number of subjects with mutations (sensitivity) for a given number of biomarkers included in the signature. For instance, by evaluating the 50 most representative point mutations, up to 81.9% of endometrial cancers can be identified in the TCGA dataset. At gene level, a 92.9% sensitivity can be obtained by interrogating five genes. DISCUSSION We developed a computational method to aid in the selection of relevant genomic biomarkers in endometrial cancer that can be adapted to other cancer types or diseases.

Abstract
Most next generation sequencing (NGS) studies identified candidate genetic variants predisposing to colorectal cancer (CRC) but do not tackle its functional interpretation to unequivocally recognize a new hereditary CRC gene. Besides, germline variants in already established hereditary CRC-predisposing genes or somatic variants share the same need when trying to categorize those with relevant significance. Functional genomics approaches have an important role in identifying the causal links between genetic architecture and phenotypes, in order to decipher cellular function in health and disease. Therefore, functional interpretation of identified genetic variants by NGS platforms is now essential. Available approaches nowadays include bioinformatics, cell and molecular biology and animal models. Recent advances, such as the CRISPR-Cas9, ZFN and TALEN systems, have been already used as a powerful tool with this objective. However, the use of cell lines is of limited value due to the CRC heterogeneity and its close interaction with microenvironment. Access to tridimensional cultures or organoids and xenograft models that mimic the in vivo tissue architecture could revolutionize functional analysis. This review will focus on the application of state-of-the-art functional studies to better tackle new genes involved in germline predisposition to this neoplasm.

Abstract
Background Preoperative chemoradiotherapy followed by surgical mesorectal resection is the standard of care for locally advanced rectal carcinomas. Yet, predicting that patients will respond to treatment remains an unmet clinical challenge. Experimental design Using laser-capture microdissection we isolated RNA from stroma and tumour glands from prospective pre-treatment samples (n = 15). Transcriptomic profiles were obtained hybridising PrimeView Affymetrix arrays. We modelled a carcinoma-associated fibroblast-specific genes filtering data using GSE39396. Results The analysis of differentially expressed genes of stroma/tumour glands from responder and non-responder patients shows that most changes were associated with the stromal compartment; codifying mainly for extracellular matrix and ribosomal components. We built a carcinoma-associated fibroblast (CAF) specific classifier with genes showing changes in expression according to the tumour regression grade (FN1, COL3A1, COL1A1, MMP2 and IGFBP5). We assessed these five genes at the protein level by means of immunohistochemical staining in a patient's cohort (n = 38). For predictive purposes we used a leave-one-out cross-validated model with a positive predictive value (PPV) of 83.3%. Random Forest identified FN1 and COL3A1 as the best predictors. Rebuilding the leave-one-out cross-validated regression model improved the classification performance with a PPV of 93.3%. An independent cohort was used for classifier validation (n = 36), achieving a PPV of 88.2%. In a multivariate analysis, the two-protein classifier proved to be the only independent predictor of response. Conclusion We developed a two-protein immunohistochemical classifier that performs well at predicting the non-response to neoadjuvant treatment in rectal cancer.

Abstract
Hypomethylation of DNA is a hallmark of cancer and its analysis as tumor biomarker has been proposed, but its determination in clinical settings is hampered by lack of standardized methodologies. Here, we present QUAlu (Quantification of Unmethylated Alu), a new technique to estimate the Percentage of UnMethylated Alu (PUMA) as a surrogate for global hypomethylation. QUAlu consists in the measurement by qPCR of Alu repeats after digestion of genomic DNA with isoschizomers with differential sensitivity to DNA methylation. QUAlu performance has been evaluated for reproducibility, trueness and specificity, and validated by deep sequencing. As a proof of use, QUAlu has been applied to a broad variety of pathological examination specimens covering five cancer types. Major findings of the preliminary application of QUAlu to clinical samples include: (1) all normal tissues displayed similar PUMA; (2) tumors showed variable PUMA with the highest levels in lung and colon and the lowest in thyroid cancer; (3) stools from colon cancer patients presented higher PUMA than those from control individuals; (4) lung squamous cell carcinomas showed higher PUMA than lung adenocarcinomas, and an increasing hypomethylation trend associated with smoking habits. In conclusion, QUAlu is a simple and robust method to determine Alu hypomethylation in human biospecimens and may be easily implemented in research and clinical settings.

Abstract
Delivery of the so-called Tumor Treatment Fields (TTFields) has been proposed as a cancer therapy. These are low magnitude alternating electric fields at frequencies from 100 to 300 kHz which are applied continuously in a non-invasive manner. Electric field delivery may produce an increase in temperature which cannot be neglected. We hypothesized that the reported results obtained by applying TTFields in vivo could be due to heat rather than to electrical forces as previously suggested. Here, an in vivo study is presented in which pancreatic tumors subcutaneously implanted in nude mice were treated for a week either with mild hyperthermia (41 °C) or with TTFields (6 V/cm, 150 kHz) and tumor growth was assessed. Although the TTFields applied singly did not produce any significant effect, the combination with chemotherapy did show a delay in tumor growth in comparison to animals treated only with chemotherapy (median relative reduction=47%). We conclude that concomitant chemotherapy and TTFields delivery show a beneficial impact on pancreatic tumor growth. Contrary to our hypothesis, this impact is non-related with the induced temperature increase.

Abstract
BACKGROUND Approximately 20% of patients with stage II colorectal cancer will experience a relapse. Current clinical-pathologic stratification factors do not allow clear identification of these high-risk patients. ColoPrint (Agendia, Amsterdam, The Netherlands, http://www.agendia.com) is a gene expression classifier that distinguishes patients with low or high risk of disease relapse. METHODS ColoPrint was developed using whole-genome expression data and validated in several independent validation cohorts. Stage II patients from these studies were pooled (n = 416), and ColoPrint was compared with clinical risk factors described in the National Comprehensive Cancer Network (NCCN) 2013 Guidelines for Colon Cancer. Median follow-up was 81 months. Most patients (70%) did not receive adjuvant chemotherapy. Risk of relapse (ROR) was defined as survival until first event of recurrence or death from cancer. RESULTS In the pooled stage II data set, ColoPrint identified 63% of patients as low risk with a 5-year ROR of 10%, whereas high-risk patients (37%) had a 5-year ROR of 21%, with a hazard ratio (HR) of 2.16 (p = .004). This remained significant in a multivariate model that included number of lymph nodes retrieved and microsatellite instability. In the T3 microsatellite-stable subgroup (n = 301), ColoPrint classified 59% of patients as low risk with a 5-year ROR of 9.9%. High-risk patients (31%) had a 22.4% ROR (HR: 2.41; p = .005). In contrast, the NCCN clinical high-risk factors were unable to distinguish high- and low-risk patients (15% vs. 13% ROR; p = .55). CONCLUSION ColoPrint significantly improved prognostic accuracy independent of microsatellite status or clinical variables, facilitating the identification of patients at higher risk who might be considered for additional treatment.

Abstract
BACKGROUND & AIMS Development of pancreatic ductal adenocarcinoma (PDAC) involves activation of c-Ki-ras2 Kirsten rat sarcoma oncogene homolog (KRAS) signaling, but little is known about the roles of proteins that regulate the activity of oncogenic KRAS. We investigated the activities of proteins that interact with KRAS in PDAC cells. METHODS We used mass spectrometry to demonstrate that heterogeneous nuclear ribonucleoproteins (HNRNP) A2 and B1 (encoded by the gene HNRNPA2B1) interact with KRAS G12V. We used co-immunoprecipitation analyses to study interactions between HNRNPA2B1 and KRAS in KRAS-dependent and KRAS-independent PDAC cell lines. We knocked down HNRNPA2B1 using small hairpin RNAs and measured viability, anchorage-independent proliferation, and growth of xenograft tumors in mice. We studied KRAS phosphorylation using the Phos-tag system. RESULTS We found that interactions between HRNPA2B1 and KRAS correlated with KRAS-dependency of some human PDAC cell lines. Knock down of HNRNPA2B1 significantly reduced viability, anchorage-independent proliferation, and formation of xenograft tumors by KRAS-dependent PDAC cells. HNRNPA2B1 knock down also increased apoptosis of KRAS-dependent PDAC cells, inactivated c-akt murine thymoma oncogene homolog 1 signaling via mammalian target of rapamycin, and reduced interaction between KRAS and phosphatidylinositide 3-kinase. Interaction between HNRNPA2B1 and KRAS required KRAS phosphorylation at serine 181. CONCLUSIONS In KRAS-dependent PDAC cell lines, HNRNPA2B1 interacts with and regulates the activity of KRAS G12V and G12D. HNRNPA2B1 is required for KRAS activation of c-akt murine thymoma oncogene homolog 1-mammalian target of rapamycin signaling, interaction with phosphatidylinositide 3-kinase, and PDAC cell survival and tumor formation in mice. HNRNPA2B1 might be a target for treatment of pancreatic cancer.

Abstract
The most studied genetic susceptibility factors involved in gastric carcinoma (GC) risk are polymorphisms in the inflammation-linked genes interleukin 1 (IL1) B and IL1RN. Despite the evidence pointing to the IL1 region, definite functional variants reproducible across populations of different genetic background have not been discovered so far. A high density linkage disequilibrium (LD) map of the IL1 gene cluster was established using HapMap to identify haplotype tagSNPs. Eighty-seven SNPs were genotyped in a Portuguese case-control study (358 cases, 1,485 controls) for the discovery analysis. A replication study, including a subset of those tagSNPs (43), was performed in an independent analysis (EPIC-EurGast) containing individuals from 10 European countries (365 cases, 1284 controls). Single SNP and haplotype block associations were determined for GC overall and anatomopathological subtypes. The most robust association was observed for SNP rs17042407, 16Kb upstream of the IL1A gene. Although several other SNP associations were observed, only the inverse association of rs17042407 allele C with GC of the intestinal type was observed in both studies, retaining significance after multiple testing correction (p = 0.0042) in the combined analysis. The haplotype analysis of the IL1A LD block in the combined dataset revealed the association between a common haplotype carrying the rs17042407 variant and GC, particularly of the intestinal type (p = 3.1 × 10(-5) ) and non cardia localisation (p = 4.6 × 10(-3) ). These results confirm the association of IL1 gene variants with GC and reveal a novel SNP and haplotypes in the IL1A region associated with intestinal type GC in European populations.

Abstract
Increased secretion of EGFR ligands amphiregulin and TGFα by limited KRAS-mutant clones is suggested as a paracrine resistance mechanism to anti-EGFR antibodies in colorectal cancer models. These findings are biologically sound but need to be replicated, including in the clinical setting, to foresee whether they are clinically relevant and therapeutically exploitable.

Abstract
SUMMARY Colorectal cancer (CRC) tumors are highly heterogeneous at a molecular level. Recent studies have proposed molecular classifications of intrinsic CRC molecular subtypes identified after applying unsupervised clustering methods to genome-wide data. Those subtypes, characterized by their distinct clinical and biological features, provide new insight about the complexity of CRC. A common finding shared by almost all analyses was the identification of microsatellite instable tumors as an independent cluster, which is associated to better prognosis. Clusters of tumors characterized by a high stromal component exhibited a poor outcome. Moreover, some of the clusters were associated with response to standard chemotherapy or targeted agents. Regarding biological functions underlying tumor subtypes, recurrent ones across different studies were WNT pathway activation, epithelial-to-mesenchymal transition or cancer stem cell-like phenotype. Now, the challenge is to translate these findings into a comprehensive CRC classification and characterization helpful for patients’ stratification and better clinical management.

Abstract
PURPOSE The microRNA-34b/c (miR-34b/c) is considered a tumor suppressor in different tumor types and a transcriptional target of TP53. The main objectives of this study were to investigate the clinical implications of miR-34b/c methylation in patients with early-stage lung adenocarcinoma and to determine the functional role of miR-34b/c re-expression in lung adenocarcinoma cell lines. EXPERIMENTAL DESIGN Aberrant methylation and expression of miR-34b/c were assessed in 15 lung adenocarcinoma cell lines and a cohort of 140 early-stage lung adenocarcinoma. Lung adenocarcinoma cell lines were transfected with miR-34b/c and the effects upon cell proliferation, migration, invasion, and apoptosis were investigated. RESULTS Aberrant methylation of miR-34b/c was detected in 6 (40%) of 15 lung adenocarcinoma cell lines and 64 of 140 (46%) primary lung adenocarcinoma. Expression of miR-34b/c was significantly reduced in all methylated cell lines and primary tumors, especially with TP53 mutations. Patients with increased miR-34b/c methylation had significantly shorter disease-free and overall survival as compared to patients with unmethylated or low level of miR-34b/c methylation. Ectopic expression of miR-34b/c in lung adenocarcinoma cell lines decreased cell proliferation, migration, and invasion. CONCLUSIONS Epigenetic inactivation of miR-34b/c by DNA methylation has independent prognostic value in patients with early-stage lung adenocarcinoma. Reexpression of miR-34b/c leads to a less aggressive phenotype in lung adenocarcinoma cell lines.

Abstract
In this article, the effectiveness of a multi-targeted chemo-switch (C-S) schedule that combines metronomic chemotherapy (MET) after treatment with the maximum tolerated dose (MTD) is reported. This schedule was tested with gemcitabine in two distinct human pancreatic adenocarcinoma orthotopic models and with cyclophosphamide in an orthotopic ovarian cancer model. In both models, the C-S schedule had the most favourable effect, achieving at least 80% tumour growth inhibition without increased toxicity. Moreover, in the pancreatic cancer model, although peritoneal metastases were observed in control and MTD groups, no dissemination was observed in the MET and C-S groups. C-S treatment caused a decrease in angiogenesis, and its effect on tumour growth was similar to that produced by the MTD followed by anti-angiogenic DC101 treatment. C-S treatment combined an increase in thrombospondin-1 expression with a decrease in the number of CD133+ cancer cells and triple-positive CD133+/CD44+/CD24+ cancer stem cells (CSCs). These findings confirm that the C-S schedule is a challenging clinical strategy with demonstrable inhibitory effects on tumour dissemination, angiogenesis and CSCs.

Abstract
Background The malignant potential of tumour cells may be influenced by the molecular nature of KRAS mutations being codon 13 mutations less aggressive than codon 12 ones. Their metabolic profile is also different, with an increased anaerobic glycolytic metabolism in cells harbouring codon 12 KRAS mutations compared with cells containing codon 13 mutations. We hypothesized that this distinct metabolic behaviour could be associated with different HIF-1α expression and a distinct angiogenic profile. Methods Codon13 KRAS mutation (ASP13) or codon12 KRAS mutation (CYS12) NIH3T3 transfectants were analyzed in vitro and in vivo. Expression of HIF-1α, and VEGF-A was studied at RNA and protein levels. Regulation of VEGF-A promoter activity was assessed by means of luciferase assays using different plasmid constructs. Vascular network was assessed in tumors growing after subcutaneous inoculation. Non parametric statistics were used for analysis of results. Results Our results show that in normoxic conditions ASP13 transfectants exhibited less HIF-1α protein levels and activity than CYS12. In contrast, codon 13 transfectants exhibited higher VEGF-A mRNA and protein levels and enhanced VEGF-A promoter activity. These differences were due to a differential activation of Sp1/AP2 transcription elements of the VEGF-A promoter associated with increased ERKs signalling in ASP13 transfectants. Subcutaneous CYS12 tumours expressed less VEGF-A and showed a higher microvessel density (MVD) than ASP13 tumours. In contrast, prominent vessels were only observed in the latter. Conclusion Subtle changes in the molecular nature of KRAS oncogene activating mutations occurring in tumour cells have a major impact on the vascular strategy devised providing with new insights on the role of KRAS mutations on angiogenesis.

Abstract
In order to assess whether inherited genetic variability in the mucin genes associates with the evolution of gastric cancer precursor lesions (GCPLs), we genotyped 22 tagSNPs in MUC1, MUC6 and MUC2 genes of 387 patients with GCPLs that had been followed up for 12.8 years. According to the diagnosis at recruitment and at the end of follow-up, the lesions did not change in 43.1% of the patients, regressed in 28.7% and progressed in 28.2%. Three SNPs in the 3'-moiety of MUC2 were significantly associated with a decreased risk of progression of the lesions, whereas another four SNPs, located at the 5'-moiety, were found to be significantly associated either with increased [one single-nucleotide polymorphism (SNP)] or decreased (three SNPs) probability of regression. Stratified analysis indicated that significance was maintained only in those subjects positive for Helicobacter pylori infection and in those not consuming non-steroidal anti-inflammatory drugs, which were found protective against lesion progression. Haplotype analyses indicated the presence of two haplotypes, one in each moiety of the gene, that were significantly associated with decreased risk of progression of the lesions [odds ratio (OR) = 0.49 and 0.46; 95% confidence interval (CI) = 0.28-0.85 and 0.25-0.86, respectively]. The 5'-end haplotype was also associated with increased probability of regression (OR = 1.67; 95% CI = 1.02-2.73), altogether suggesting a protective role against progression of the precancerous lesions. No significant association was found with variants in MUC1 and MUC6 genes. These results indicate, for the first time, that genetic variability in MUC2 is associated with evolution of GCPLs, especially in H.pylori infected patients, suggesting a role of this secreted mucin in gastric carcinogenesis.

Abstract
Dermal neurofibromas (dNFs) are benign tumors of the peripheral nervous system typically associated with Neurofibromatosis type 1 (NF1) patients. Genes controlling the integrity of the DNA are likely to influence the number of neurofibromas developed because dNFs are caused by somatic mutational inactivation of the NF1 gene, frequently evidenced by loss of heterozygosity (LOH). We performed a comprehensive analysis of the prevalence and mechanisms of LOH in dNFs. Our study included 518 dNFs from 113 patients. LOH was detected in 25% of the dNFs (N = 129). The most frequent mechanism causing LOH was mitotic recombination, which was observed in 62% of LOH-tumors (N = 80), and which does not reduce the number of NF1 gene copies. All events were generated by a single crossover located between the centromere and the NF1 gene, resulting in isodisomy of 17q. LOH due to the loss of the NF1 gene accounted for a 38% of dNFs with LOH (N = 49), with deletions ranging in size from ∼80 kb to ∼8 Mb within 17q. In one tumor we identified the first example of a neurofibroma-associated second-hit type-2 NF1 deletion. Analysis of the prevalence of mechanisms causing LOH in dNFs in individual patients (possibly under genetic control) will elucidate whether there exist interindividual variation.

Abstract
Allelic imbalances at chromosome 4p have been largely documented in many different tumor types. In colorectal cancer, loss of heterozygosity (LOH) at 4p15 has been associated with tumor aggressiveness and poor patient outcome, however no target genes in the region have been identified to date. Since stromal interaction molecule 2 (STIM2) is located at 4p15.2 and has been proposed as a candidate gene for this region in glioblastoma multiforme, we aimed at investigating the role of STIM2 in colorectal cancer. We studied STIM2 transcript expression levels in a collection of xenografted primary colorectal tumors (n = 20) and a well-annotated tumor series of colorectal cancer (n = 140). We observed an overexpression of STIM2 in 63.5% of the cases that was associated with a less invasive phenotype. In vitro and in vivo functional studies with colon cancer cell lines revealed that overexpression of STIM2 reduced cell proliferation and tumor growth, respectively. Our work presents several lines of evidence indicating that STIM2 overexpression is a frequent trait in colorectal cancer that results in cell growth suppression, certifying that even in the absence of somatic genetic or epigenetic alterations, recurrent regions of LOH should still be considered a hallmark for the presence of relevant genes for tumorigenesis.

Abstract
Background: Defective DNA repair has a causal role in hereditary colorectal cancer (CRC). Defects in the base excision repair gene MUTYH are responsible for MUTYH-associated polyposis and CRC predisposition as an autosomal recessive trait. Numerous reports have suggested MUTYH mono-allelic variants to be low penetrance risk alleles. We report a large collaborative meta-analysis to assess and refine CRC risk estimates associated with bi-allelic and mono-allelic MUTYH variants and investigate age and sex influence on risk. Methods: MUTYH genotype data were included from 20 565 cases and 15 524 controls. Three logistic regression models were tested: a crude model; adjusted for age and sex; adjusted for age, sex and study. Results: All three models produced very similar results. MUTYH bi-allelic carriers demonstrated a 28-fold increase in risk (95% confidence interval (CI): 6.95–115). Significant bi-allelic effects were also observed for G396D and Y179C/G396D compound heterozygotes and a marginal mono-allelic effect for variant Y179C (odds ratio (OR)=1.34; 95% CI: 1.00–1.80). A pooled meta-analysis of all published and unpublished datasets submitted showed bi-allelic effects for MUTYH, G396D and Y179C (OR=10.8, 95% CI: 5.02–23.2; OR=6.47, 95% CI: 2.33–18.0; OR=3.35, 95% CI: 1.14–9.89) and marginal mono-allelic effect for variants MUTYH (OR=1.16, 95% CI: 1.00–1.34) and Y179C alone (OR=1.34, 95% CI: 1.01–1.77). Conclusions: Overall, this large study refines estimates of disease risk associated with mono-allelic and bi-allelic MUTYH carriers.

Abstract
Due to their ability to metabolize xenobiotics, glutathione S-transferases (GSTs) play an important role in cellular protection. GST family members mu (GSTM1) and theta (GSTT1) exhibit a common polymorphism that results in the complete deletion of the gene (null allele). Homozygous deletions, which result in the absence of the enzyme, are considered a risk factor for several diseases, including cancer. We report a simple, low cost, and high throughput assay for the simultaneous analysis of the GSTM1 and GSTT1 null polymorphisms in a single step. The assay is based on multiplex real-time PCR in the presence of SYBR Green I and genotype discrimination by melting curve analysis in a LightCycler. We have genotyped 792 samples to compare this new approach with conventional PCR followed by gel electrophoresis. Comparison of the methods gave a good agreement, with kappa values of 0.88 for GSTM1 and 0.64 for GSTT1. Reanalysis of discrepant samples indicated that absence of amplification of the larger GSTT1 fragment by conventional PCR accounted for most of the discrepancies. Moreover, the improved amplification efficiency of the real-time PCR results in a significant reduction of missing values. Due to its simplicity and low cost, this assay is well suited for the rapid analysis of GST-null genotypes in studies that involve large number of samples.

Abstract
Actin-binding proteins filamin A (FLNA) and B (FLNB) are expressed in endothelial cells and play an essential role during vascular development. In order to investigate their role in adult endothelial cell function, we initially confirmed their expression pattern in different adult mouse tissues and cultured cell lines and found that FLNB expression is concentrated mainly in endothelial cells, whereas FLNA is more ubiquitously expressed. Functionally, small interfering RNA knockdown of endogenous FLNB in human umbilical vein endothelial cells inhibited vascular endothelial growth factor (VEGF)-induced in vitro angiogenesis by decreasing endothelial cell migration capacity, whereas FLNA ablation did not alter these parameters. Moreover, FLNB-depleted cells increased their substrate adhesion with more focal adhesions. The molecular mechanism underlying this effect implicates modulation of small GTP-binding protein Rac-1 localization and activity, with altered activation of its downstream effectors p21 protein Cdc42/Rac-activated kinase (PAK)-4/5/6 and its activating guanine nucleotide exchange factor Vav-2. Moreover, our results suggest the existence of a signaling complex, including FLNB, Rac-1, and Vav-2, under basal conditions that would further interact with VEGFR2 and integrin alphavbeta5 after VEGF stimulation. In conclusion, our results reveal a crucial role for FLNB in endothelial cell migration and in the angiogenic process in adult endothelial cells.

Abstract
Large chromosomal regions can be suppressed in cancer cells as denoted by hypermethylation of neighbouring CpG islands and downregulation of most genes within the region. We have analysed the extent and prevalence of long-range epigenetic silencing at 2q14.2 (the first and best characterised example of coordinated epigenetic remodelling) and investigated its possible applicability as a non-invasive diagnostic marker of human colorectal cancer using different approaches and biological samples. Hypermethylation of at least one of the CpG islands analysed (EN1, SCTR, INHBB) occurred in most carcinomas (90%), with EN1 methylated in 73 and 40% of carcinomas and adenomas, respectively. Gene suppression was a common phenomenon in all the tumours analysed and affected both methylated and unmethylated genes. Detection of methylated EN1 using bisulfite treatment and melting curve (MC) analysis from stool DNA in patients and controls resulted in a predictive capacity of, 44% sensitivity in positive patients (27% of overall sensitivity) and 97% specificity. We conclude that epigenetic suppression along 2q14.2 is common to most colorectal cancers and the presence of a methylated EN1 CpG island in stool DNA might be used as biomarker of neoplastic disease.

Abstract
Gemcitabine shows a marked antitumor effect as a result of its cytotoxic action toward proliferative cells. In this article, we aim to investigate the potential antitumor and antiangiogenic effect of gemcitabine following a metronomic schedule that involves the regular administration of cytotoxic drugs at doses lower than standard treatment. In vitro results showed that human endothelial cells are more sensitive to gemcitabine (IC(50) 3 nmol/L) than pancreatic tumor cells (IC(50) 20 nmol/L). For in vivo studies, we used an orthotopic implantation model of human pancreatic carcinoma in nude mice. Gemcitabine was administered i.p. following a low-dose schedule (1 mg/kg/d for a month) and compared with the conventional schedule (100 mg/kg days 0, 3, 6, and 9 postimplantation). Metronomic treatment effect on established tumor was equivalent to standard administration. The measure of CD31 endothelial marked area allowed us to show an in vivo antiangiogenic effect of this drug that was further enhanced by using metronomic administration. This effect correlated with an induction of thrombospondin-1, a natural inhibitor of angiogenesis. Our results allow us to hypothesize that, in addition to a direct antiproliferative or cytotoxic antiendothelial cell effect, a secondary effect involving thrombospondin-1 induction might provide an explanation for the specificity of the effects of metronomic gemcitabine treatment.

Abstract
DNA hypomethylation is a common trait of colorectal cancer. Studies in tumor cell lines and animal models indicate that genome-wide demethylation may cause genetic instability and hence facilitate or accelerate tumor progression. Recent studies have shown that DNA hypomethylation precedes genomic damage in human gastrointestinal cancer, but the nature of this damage has not been clearly established. Here, we show a thorough analysis of DNA methylation and genetic alterations in two series of colorectal carcinomas. The extent of DNA demethylation but not of hypermethylation (both analyzed by amplification of intermethylated sites in near 200 independent sequences arbitrarily selected) correlated with the cumulated genomic damage assessed by two different techniques (arbitrarily primed PCR and comparative genomic hybridization). DNA hypomethylation-related instability was mainly of chromosomal nature and could be explained by a genome-wide effect rather than by the concurrence of the most prevalent genetic and epigenetic alterations. Moreover, the association of p53 mutations with genomic instability was secondary to DNA hypomethylation and the correlation between DNA hypomethylation and genomic instability was observed in tumors with and without mutation in the p53 gene. Our data support a direct link between genome-wide demethylation and chromosomal instability in human colorectal carcinogenesis and are consistent with the studies in model systems demonstrating a role of DNA demethylation in inducing chromosomal instability.

Abstract
INTRODUCTION Changes in breast cancer cell biology following hormonal treatment have been claimed as promising predictor markers of clinical benefit even outperforming clinical response. From previous work we selected 10 genes showing both a well known regulation by oestrogen and a high level of early transcriptional regulation following therapy with aromatase inhibitors. Here we use an animal breast cancer model to explore the feasibility of the determination of their expression in minimally invasive samples and to further assess the magnitude of their regulation by letrozole. ANIMAL AND METHODS: Aromatase inhibitor sensitive breast cancer tumours were grown in athymic mice under supplement with androstenedione. Following initial tumour growth animals were assigned to a control group or to receive letrozole at two different dosages. Fine needle aspirates were obtained at the moment of treatment assignation and one week later. Expression of the following genes at both time points was determined: Ki-67, Cyclin D1, pS2, Trefoil Factor 3, PDZ domain containing 1, Ubiquitin-conjugating enzyme E2C, Stanniocalcin 2, Topoisomerase 2 alfa, MAN1A1 and FAS. RESULTS Fine needles aspirates were found to be a feasible and reproducible technique for RNA extraction. Trefoil Factor 3, pS2, Cyclin D1 and Stanniocalcin 2 were significantly downregulated by letrozole. Among them pS2 appears to be most sensitive to aromatase inhibitor treatment even differentiating sub-optimal from optimal letrozole dosage. DISCUSSION We present pre-clinical evidence to justify the exploration in clinical trials of pS2, Trefoil factor 3, Cyclin D1 and Stanniocalcin as dynamic markers of oestrogen-driven pathway activation.

Abstract
The advent of various 'omic' technologies has increased expectations in the field of biomarkers. In an attempt to clarify how different strategies may contribute to improving prognostic classification and to identify new predictors of patient outcome we analyzed genomic and transcriptomic profiles in a series of R0 Dukes B and C colorectal carcinomas. We have compared the predictive capability of each approach against conventional clinicopathological and molecular parameters. At a genomic level, gains at 11q including amplification at 11q13 were an indicator of poorer outcome. In transcriptomic analyses we identified 68 genes whose expression levels correlated with survival (p<0.01) and included overexpression of WASF1, NFE2L2, and MMP9, and underexpression of ITGAL, TSC2, and SDF2. Gene expression levels paralleled chromosomal changes only in 56% of the genes, suggesting that, as a general trend, the direct effect of chromosomal copy number changes on gene expression levels is minimal. Classification of tumors by genomic and transcriptomic signatures resulted in non-overlapping subgroups and was not of prognostic value. We conclude that genomic and transcriptomic profiling of colorectal carcinomas may contribute as novel prognostic markers, but it does not improve outcome prediction when global profiles or signatures are considered.

Abstract
The aim of this study was to analyze the prognostic value of TP53 mutations in a consecutive series of patients with hepatic metastases (HMs) from colorectal cancer undergoing surgical resection. Ninety-one patients with liver metastases from colorectal carcinoma were included. Mutational analysis of TP53, exons 4-10, was performed by single-strand conformation polymorphism and sequencing. P53 and P21 protein immunostaining was assessed. Multivariate Cox models were adjusted for gender, number of metastasis, resection margin, presence of TP53 mutations and chemotherapy treatment. Forty-six of 91 (50.05%) metastases showed mutations in TP53, observed mainly in exons 5-8, although 14.3% (n = 13) were located in exons 9 and 10. Forty percent (n = 22) were protein-truncating mutations. TP53 status associated with multiple (> or =3) metastases (65.6%, P = 0.033), advanced primary tumor Dukes' stage (P = 0.011) and younger age (<57 years old, P = 0.03). Presence of mutation associated with poor prognosis in univariate (P = 0.017) and multivariate Cox model [hazard ratio (HR) = 1.80, 95% confidence interval (CI) = 1.07-3.06, P = 0.028]. Prognostic value was maintained in patients undergoing radical resection (R0 series, n = 79, P = 0.014). Mutation associated with a worse outcome in chemotherapy-treated patients (HR = 2.54, 95% CI = 1.12-5.75, P = 0.026). The combination of > or =3 metastases and TP53 mutation identified a subset of patients with very poor prognosis (P = 0.009). P53 and P21 protein immunostaining did not show correlation with survival. TP53 mutational status seems to be an important prognostic factor in patients undergoing surgical resection of colorectal cancer HMs.

Abstract
OBJECTIVES We have undertaken a comprehensive study of common polymorphisms in genes of DNA repair, exploring both the risk of developing colorectal cancer and the prognosis of patients. METHODS Subjects from a case-control study (377 cases and 329 controls) designed to assess gene-environment interactions were genotyped by use of an oligonucleotide microarray and the arrayed primer extension technique. Twenty-eight single nucleotide polymorphisms in 15 DNA repair genes were included. The candidate genes belong to different DNA repair pathways: base excision repair (OGG1, LIG3, APEX, POLB, XRCC1, PCNA, and MUTYH), nucleotide excision repair (ERCC1, ERCC2, ERCC4, and ERCC5), double-strand breaks repair (XRCC2, XRCC3, and XRCC9), and reversion repair (MGMT) genes. RESULTS Polymorphism OGG1 S326C was associated with an increased risk of colorectal cancer [odds ratio (OR), 2.3; 95% confidence interval (95% CI), 1.1-5.0], the risk being higher in younger individuals. A haplotype of ERCC1 was associated with increased risk (OR, 2.3; 95% CI, 1.0-5.3). POLB P242R was also associated with decreased risk (OR, 0.23; 95% CI, 0.05-0.99), although the number of variant allele carriers was low. In the univariate analysis, adjusted for age, sex, and Dukes' stage, three polymorphisms were significantly associated with better prognosis: XRCC1 R399Q [hazard ratio (HR), 0.38; 95% CI, 0.17-0.85], XRCC3 T141M (HR, 0.66; 95% CI, 0.45-0.97), and MGMT L84F (HR, 0.14; 95% CI, 0.02-0.99). ERCC1 19007T>C was associated with worse prognosis (HR, 1.51; 95% CI, 1.01-2.27). In a multivariate analysis, only XRCC1 R399Q and ERCC1 19007T>C remained significant. These associations were stronger among patients receiving adjuvant chemotherapy. CONCLUSIONS Although the overall effect of DNA repair genes in colorectal cancer etiology seems limited, their influence in the response to chemotherapy and prognosis may be more relevant. This knowledge may help to clarify the utility of specific adjuvant treatments according to the individual genetic background.

Abstract
BACKGROUND Mdm2 is a natural inhibitor of p53 function and its overexpression impairs p53 transcriptional activity. T-->G single-nucleotide polymorphism at position 309 (SNP309) of mdm2 induces overexpression of mdm2, but inhibits p53. OBJECTIVES To determine whether SNP309 is a risk-modifier polymorphism in colorectal cancer (CRC) and whether tumour selection of P53 mutations are influenced by SNP309. METHODS Single-stranded conformation polymorphism and automatic sequencing were performed. RESULTS SNP309 is not associated with the risk of CRC or recurrence of tumours. These data do not over-ride the tumour-selection capabilities of P53 mutations in CRC. However, a significant association with non-dominant-negative P53 mutations (p = 0.02) was found. CONCLUSIONS MDM2-SNP309 favours tumour selection of non-dominant negative P53 mutations in CRC, which also show an earlier age of tumour onset.

Abstract
Different mutant amino acids in the Ras proteins lead to distinct transforming capacities and different aggressiveness in human tumors. K-Ras Asp12 (K12D) is more prevalent in benign than in malignant human colorectal tumors, whereas K-Ras Val12 (K12V) associates with more advanced and metastatic carcinomas, higher recurrence and decreased survival. Here, we tested, in a nude mouse xenograft model, whether different human K-Ras oncogenes mutated at codon 12 to Val, Asp or Cys would confer NIH3T3 fibroblasts distinct oncogenic phenotypes. We studied tumor histology and growth, apoptotic and mitotic rates, activation of signal transduction pathways downstream of Ras and regulation of the cell cycle and apoptotic proteins in tumors derived from the implanted transformants. We found that the K12V oncogene induces a more aggressive tumorigenic phenotype than the K12D oncogene, whereas K12C does not induce tumors in this model. Thus, K12V mutant tumors proliferate about seven times faster, and have higher cellularity and mitotic rates than the K12D mutant tumors. A molecular analysis of the induced tumors shows that the K12V mutant protein interacts with Raf-1 and transduces signals mainly through the Erk pathway. Unexpectedly, in tumors induced by the K12D oncogene, the K-Ras mutant protein does not interact with Raf-1 nor activates the Erk canonical pathway. Instead, it transduces signals through the PI3K/Akt, JNK, p38 and FAK pathways. Finally, the higher growth rate of the K12V tumors associates with enhanced Rb phosphorylation, and PCNA and cyclin B upregulation, consistent with faster G1/S and G2/M transitions, without alteration of apoptotic regulation.

Abstract
The accumulation of multiple chromosomal abnormalities is a characteristic of the majority of colorectal cancers and has been attributed to an underlying chromosomal instability. Genetic instability is considered to have a key role in the generation of genetic and phenotypic heterogeneity in cancer cells. To shed light on the dynamics of chromosomal instability in colon cancer cells, we have analyzed genetic divergence in clonal and subclonal derivates of chromosomally unstable (SW480) and stable (HCT116, LoVo) cell lines. Conventional G-banding karyotyping and arbitrarily primed PCR (AP-PCR) fingerprinting were used to calculate genetic distances among clones and parental cells, and to trace tree-type phylogenies among individual cells and clonal cell populations. SW480 cells showed enhanced karyotypic heterogeneity in clones as compared with parental cells. Moreover, genetic clonal divergence was also increased after two consecutive episodes of single-cell cloning, demonstrating that the homogeneity induced by the bottleneck of cloning is disrupted by genetic instability during clonal expansion and, as a consequence, heterogeneity is restored. These results demonstrate genetic drift in clonal populations originated from isolated cells. The generated cell heterogeneity coupled with selection provides the grounds for the reported feasibility of pre-neoplastic and neoplastic cells to generate new phenotypic variants with increased evolutionary potential.

Abstract
OBJECTIVES Sporadic colorectal cancer (CRC) is considered a multifactorial disease where multiple exposures interact with the individual genetic background resulting in risk modulation. We performed an association study aimed to investigate the role of single nucleotide polymorphisms (SNPs) within genes of phase I (CYP1A1, CYP1A2, CYP1B1, CYP2A6, CYP2D6, CYP2E1, CYP2C9, CYP2C19, CYP3A4, ADH2, EPHX1) and phase II of the xenobiotic metabolism (ALDH2, COMT, GSTA2, GSTA4, GSTM1, GSTM3, GSTP1, GSTT2, MTHFR, NAT1, NAT2, NQO1, MnSOD2, SULT1A1, TPMT). METHODS We genotyped 377 cases and 326 controls, by use of an oligonucleotide micro-array and the arrayed primer extension technique (APEX). RESULTS N-acetyl-transferase 1 'rapid' phenotype and CYP1A2 -164C>A carriers were associated with increased risk of CRC, confirming data reported in previous studies. Interestingly, homozygotes for allele 48G within CYP1B1, a variant with an increased activity towards several substrates including sex hormones, were at increased risk (OR=2.81, 95% CI 1.32-5.99). Moreover, CYP1A1 SNPs T461N and -1738A>C were associated with a reduced risk of cancer (OR=0.52; 95% CI 0.31-0.88 and OR=0.69, 95% CI 0.50-0.94 for carriers, respectively). CONCLUSIONS The present data suggest a role for CYP1B1 and CYP1A1 as new candidate genes in the etiology of CRC and confirm the carcinogenic role of aromatic amines metabolism for colorectum.

Abstract
Human pancreatic adenocarcinomas are highly resistant to conventional treatment modalities, specially to chemotherapy. Among the genes that modulate apoptosis in response to cytotoxic drugs, the role of p53 has been demonstrated to be of paramount importance. Moreover, p53 is mutated in close to 50% of pancreatic cancer, which renders attractive the reintroduction of this gene as a way to enhance the action of chemotherapeutics. In this paper, gemcitabine, the most effective drug for the treatment of pancreatic tumors, has been selected to develop a new combination approach in vivo based on an administration schedule previously optimized in vitro. In a human xenograft model, the sequential administration of gemcitabine and p53 resulted in potent tumor growth inhibition. Statistical differences were observed with respect to the growth of tumors receiving only gemcitabine or p53. Moreover, the chemosensitization observed in tumors treated with the combination gemcitabine-p53 correlated with differential histological features such as important increases in intratumoral fibrosis and apoptotic levels, when compared with unimodal treatments. Taken together, our data indicate that reintroduction of p53 function in human pancreatic tumors in vivo allows to restore molecular pathways improving the response to gemcitabine. It may constitute a useful step towards a better clinical treatment of patients harboring pancreatic cancer.

Abstract
Inactivation of specific tumor suppressor genes by transcriptional silencing associated with hypermethylation of the promoter is a common event in cancer. We have applied the amplification of intermethylated sites (AIMS) technique to a 100 human colorectal cancers and seven cell lines to identify recurrent alterations that may unveil silenced tumor suppressor genes. Bisulfite sequencing was used to confirm differential DNA methylation results. Gene expression analysis was performed by real-time RT-PCR. An AIMS band recurrently displayed in tumors but not in normal tissues was isolated and identified as part of the CpG island of the prostacyclin synthase (PTGIS) gene promoter. PTGIS promoter was hypermethylated in 43 out of 100 colorectal cancers and in all cell lines. Bisulfite sequencing and clonal analysis confirmed the results obtained by AIMS and demonstrated biallelic hypermethylation of PTGIS promoter. Hypermethylation of the PTGIS promoter was associated with diminished gene expression, that was restored after treatment with demethylating and histone deacetylases inhibitor agents. PTGIS hypermethylation was associated with aneuploidy and p53 mutations. In the adjusted model, PTGIS methylation, but not p53 mutation, maintained the association with aneuploidy. We conclude that epigenetic inactivation of the PTGIS gene is a recurrent alteration in colorectal carcinogenesis.

Abstract
Sporadic colorectal cancer is considered a multifactorial disease in which multiple exposures interact with the individual genetic background resulting in risk modulation. Recent experimental data suggest a role of dopamine and dopamine receptors in the control of proliferation of the cells of colon and gastrointestinal tract. To investigate whether polymorphisms within dopamine receptors genes could have a role in modulating the risk of sporadic colorectal cancer, we did a case-control association study and genotyped 370 cases and 327 controls for seven single-nucleotide polymorphisms (SNP) of DRD2 (-141Cdel, 957T>C, TaqIB, TaqIA, 1412A>G, S311C, and 3208G>T) by a microarray-based technique. Three SNPs within DRD2 were associated with colorectal cancer, with a maximum odds ratio of 2.28 (95% confidence interval, 1.38-3.76) for carriers of the functional SNP -141Cdel. The haplotype which includes -141Cdel, together with the variants 957C and 1412G, shows an odds ratio of 2.86 (95% confidence interval, 1.58-5.18), as compared with the most frequent haplotype. The SNPs within DRD2 associated with colorectal cancer are known to be related to reduced levels of D2 dopamine receptor. Thus, our data point to a possible role of dopamine receptor DRD2 in modulating the risk of colorectal cancer. Future studies on dopamine receptor-mediated signal transduction may provide new insight into the mechanisms of colorectal cancer and suggest new therapeutic strategies.

Abstract
Colorectal cancer progression is characterized by the sequential acquisition of multiple genetic aberrations. Insights into the biology of cancer cell and the development of novel methodologies have open a new frontier in the search of independent molecular factors to better predict outcome. Besides the generation of a large list of candidate markers, their applicability in routine clinical settings has been hindered by the heterogeneity of the disease. The analysis of cumulated genetic damage offers a more comprehensive measure of the cancer cell's genomic disruption and appears as a gauge of malignant potential. The prognostic application of different determinants of genomic damage is reviewed.
