Abstract
Cutaneous squamous cell carcinoma (cSCC) is a common type of skin cancer that can result in significant morbidity, although it is usually well-managed and rarely metastasizes. However, the lack of commercially available cSCC cell lines hinders our understanding of this disease. This study aims to establish and characterize a new metastatic cSCC cell line derived from a Brazilian patient. A tumor biopsy was taken from a metastatic cSCC patient, immortalized, and named HCB-541 after several passages. The cytokeratin expression profile, karyotypic alterations, mutational analysis, mRNA and protein differential expression, tumorigenic capacity in xenograft models, and drug sensitivity were analyzed. The HCB-541 cell line showed a doubling time between 20 and 30 h and high tumorigenic capacity in the xenograft mouse model. The HCB-541 cell line showed hypodiploid and hypotetraploidy populations. We found pathogenic mutations in TP53 p.(Arg248Leu), HRAS (Gln61His) and TERT promoter (C228T) and high-level microsatellite instability (MSI-H) in both tumor and cell line. We observed 37 cancer-related genes differentially expressed when compared with HACAT control cells. The HCB-541 cells exhibited high phosphorylated levels of EGFR, AXL, Tie, FGFR, and ROR2, and high sensitivity to cisplatin, carboplatin, and EGFR inhibitors. Our study successfully established HCB-541, a new cSCC cell line that could be useful as a valuable biological model for understanding the biology and therapy of metastatic skin cancer.

Abstract
OBJECTIVE This study aimed to evaluate the association between self-reported race/color and ancestry in Brazilian patients with breast cancer. METHODS This was an observational, transversal, epidemiological study, evaluating race and ancestry in 1,127 patients with breast cancer. For genetic ancestry, a 46-AIM-INDEL panel was used. The ancestral profile was evaluated with the Structure v.2.3.3 software. Descriptive statistics were performed. To assess differences between race and ancestry, an analysis of variance with Bonferoni adjustment was used. RESULTS The race distribution was 77.7% white, 17.6% brown, 4.1% black, 0.4% yellow, and 0.3% cafuse. The African ancestry proportion was significantly (p<0.001) more evident in black [0.63±0.21 (0.17-0.96)], followed by brown [0.25±0.16 (0.02-0.70)], and less frequent in white skin color. The European ancestry proportion was significantly (p<0.001) higher in white [0.72±0.17 (0.02-0.97)], followed by brown [0.57±0.19 (0.12-0.92)], yellow [0.27±0.31 (0.12-0.620], and black [0.24±0.19 (0.02-0.72)]. The Asiatic ancestry proportion is significantly (p<0.001) higher in yellow [0.48±0.51 (0.04-0.93)]. The Amerindian ancestry proportion frequency was the least frequent in all groups, and cafuse patients did not express differences between all race groups. The brown race group presented differences in African and European ancestry. CONCLUSION Although we found many similarities between white European ancestry, black African ancestry, and yellow Asian ancestry, there is great miscegenation between patients. Although they can be labeled as having one race, they do present many ancestral genes that would allow their inclusion in another race group.

Abstract
OBJECTIVE To better understand the immune microenvironment of pancreatic ductal adenocarcinomas (PDACs), here we explored the relevance of T and B cell compartmentalisation into tertiary lymphoid structures (TLSs) for the generation of local antitumour immunity. DESIGN We characterised the functional states and spatial organisation of PDAC-infiltrating T and B cells using single-cell RNA sequencing (scRNA-seq), flow cytometry, multicolour immunofluorescence, gene expression profiling of microdissected TLSs, as well as in vitro assays. In addition, we performed a pan-cancer analysis of tumour-infiltrating T cells using scRNA-seq and sc T cell receptor sequencing datasets from eight cancer types. To evaluate the clinical relevance of our findings, we used PDAC bulk RNA-seq data from The Cancer Genome Atlas and the PRINCE chemoimmunotherapy trial. RESULTS We found that a subset of PDACs harbours fully developed TLSs where B cells proliferate and differentiate into plasma cells. These mature TLSs also support T cell activity and are enriched with tumour-reactive T cells. Importantly, we showed that chronically activated, tumour-reactive T cells exposed to fibroblast-derived TGF-β may act as TLS organisers by producing the B cell chemoattractant CXCL13. Identification of highly similar subsets of clonally expanded CXCL13 + tumour-infiltrating T cells across multiple cancer types further indicated a conserved link between tumour-antigen recognition and the allocation of B cells within sheltered hubs in the tumour microenvironment. Finally, we showed that the expression of a gene signature reflecting mature TLSs was enriched in pretreatment biopsies from PDAC patients with longer survival after receiving different chemoimmunotherapy regimens. CONCLUSION We provided a framework for understanding the biological role of PDAC-associated TLSs and revealed their potential to guide the selection of patients for future immunotherapy trials.

Abstract
BACKGROUND Metastatic lymph node involvement influences therapy decisions and serves as a prognostic indicator in oral squamous cell carcinoma (OSCC). However, many early-stage patients with clinically negative lymph nodes exhibit no metastasis upon surgical staging. This study aimed to identify differentially expressed miRNAs capable of distinguishing pathologically positive (pN+) from negative (pN0) nodes in OSCC patients without clinical evidence of lymph node metastases (cN0). METHODS Expression levels of 798 miRNAs were assessed in tumor samples from 10 pN+ and 10 pN0 patients using the Nanostring nCounter platform. Validation was performed in an independent cohort of 15 pN+ and 24 pN0 patients through RT-qPCR. RESULTS Eight miRNAs exhibited differential expression between pN0 and pN+ patients. Notably, hsa-miR-99a-5p demonstrated high sensitivity and specificity in predicting patients at higher risk of positive lymph nodes. CONCLUSIONS These findings highlight hsa-miR-99a-5p as a potential biomarker for detecting lymph node metastasis in primary OSCC tumors.

Abstract
OBJECTIVES MCL-1 and PD-L1 proteins are related to carcinogenesis mechanisms in differentiated thyroid carcinoma(DTC). Tumor antigens stimulate the expression of PD-1 in immune cells, which binds to PD-L1 of tumor cells, inducing immune escape from the tumor. MCL-1, an anti-apoptotic member of the BCL-2 family, is necessary for the survival of T and B lymphocytes and has a high oncogenic potential. We aim to evaluate the clinical utility and relevance of MCL-1 and PD-L1 in the long-term prognosis of DTC. METHODS 120 DTC patients after total thyroidectomy and radioiodine therapy followed for a minimum of 2 years were included. Demographic features, tumor histopathology, persistence/recurrence risk, factors associated with outcome, initial response to therapy, persistence or disease-free at the follow-up were related to MCL-1 and PD-L1 immunohistochemical expression and BRAFV600E mutation. RESULTS 100(83.3%) were women, 46.64 ± 16.73 years old at diagnosis; 37(30.8%) patients were at high, 45(37.5%) of intermediate and 38(31.7%) of low disease recurrence/persistence risk. At the end of follow-up of 124.86 ± 65.36 months, 48(42.5%) had persistent disease. 103(85.8%) patients had papillary thyroid carcinoma (PTC), 17(14.2%) follicular thyroid carcinoma (FTC). In PTC, moderate/strong PD-L1 and MCL-1 expressions were associated to BRAFV600E (p=0.0467; p=0.0044). PD-L1 was also associated with tall cell subtype (p=0.0274). In FTC, weak PD-L1 expression was associated to the largest nodule diameter (p=0.0100). Strong/moderate PD-L1 expression was associated to T2 and the weak expression with T3 in TNM classification (p=0.0490). Moderate MCL-1 expression was associated to smoking (p=0.0350). CONCLUSIONS PDL-1, marker of progression of tumor cells and MCL-1, anti-apoptotic marker, were associated with PTC carrying BRAFV600E mutation, while PDL-1 was associated with more aggressive PTC subtype. MCL-1 and PD-L1 could be useful in composing a panel to assess the prognosis of PTC patients. On the other hand, both markers seemed to have lower relevance to FTC patients.

Abstract
PURPOSE Breast cancer molecular subtypes show significant differences in different ethnic groups in the United States, but no study has evaluated genetic ancestry in breast cancer in Brazilian women. METHODS Breast cancer patients from distinct parts of Brazil were evaluated. Molecular subtypes were determined by immunohistochemistry. Genetic ancestry was evaluated using a panel of 46 AIMs (ancestry informative markers), which classified genetic ancestry as European, African, Asian, and Amerindian. PCR products were subjected to capillary electrophoresis and analyzed using GeneMapper 4.0 software. Ancestry was evaluated with Structure v.2.3.3 software. Ancestry was tested for correlations with geographic region and molecular subtype. The chi-square test and ANOVA with Bonferroni adjustment were applied. RESULTS Genetic ancestry and clinical data were evaluated in 1127 patients. Higher rates of self-reported white ethnicity, European ancestry, and HER-2- luminal tumors were identified in the South region, which may influence age at diagnosis and result in a higher rate of early tumors. Conversely, higher rates of African ancestry in the North and Northeast regions, self-reported nonwhite ethnicity, HER-2+ tumors, and triple-negative tumors were noted. Triple-negative and HER-2+ tumors were associated with higher advanced and metastatic disease rates at diagnosis, with triple-negative tumors being more frequent in young women. CONCLUSION Differences in genetic ancestry, self-reported ethnicity, and molecular subtype were found between Brazilian demographic regions. Knowledge of these features may contribute to a better understanding of age at diagnosis and the molecular distribution of breast cancer in Brazil.

Abstract
BRAF and TERT oncogenes hotspot mutations are associated with a more aggressive outcome in thyroid carcinomas (TC). TERT promoter (pTERT) mutations (C228T and C250T) are related to cancer growth and reduced overall- and disease-free survivals in TC. We report a patient followed up for 8 years with a poorly differentiated thyroid carcinoma (PDTC) presenting an extremely aggressive course, who developed a large volume of metastases in a short period. Molecular analysis of the primary tumor revealed two pTERT mutations (C228T and C250T), and no BRAF V600E mutation. pTERT mutations C228T and C250T have been described as mutually exclusive, indicating that one mutation is enough for telomerase activation and exerts its action in thyroid tumorigenesis. This report describes both pTERT hotspot mutations in the same PDTC patient presenting a very aggressive course, even for PDTC, suggesting a relationship between the two events. However, more studies are needed to prove this causality.

Abstract
Background: EGFR mutations are present in approximately 15−50% of non-small cell lung cancer (NSCLC), which are predictive of anti-EGFR therapies. At variance, NSCLC patients harboring KRAS mutations are resistant to those anti-EGFR approaches. Afatinib and allitinib are second-generation pan-EGFR drugs, yet no predictive biomarkers are known in the NSCLC context. In the present study, we evaluated the efficacy of pan-EGFR inhibitors in a panel of 15 lung cancer cell lines associated with the KRAS mutations phenotype. Methods: KRAS wild-type sensitive NCI-H292 cell line was further transfected with KRAS mutations (p.G12D and p.G12S). The pan-EGFR inhibitors’ activity and biologic effect of KRAS mutations were evaluated by cytotoxicity, MAPK phospho-protein array, colony formation, migration, invasion, and adhesion. In addition, in vivo chicken chorioallantoic membrane assay was performed in KRAS mutant cell lines. The gene expression profile was evaluated by NanoString. Lastly, everolimus and pan-EGFR combinations were performed to determine the combination index. Results: The GI50 score classified two cell lines treated with afatinib and seven treated with allitinib as high-sensitive phenotypes. All KRAS mutant cell lines demonstrated a resistant profile for both therapies (GI50 < 30%). The protein array of KRAS edited cells indicated a significant increase in AKT, CREB, HSP27, JNK, and, importantly, mTOR protein levels compared with KRAS wild-type cells. The colony formation, migration, invasion, adhesion, tumor perimeter, and mesenchymal phenotype were increased in the H292 KRAS mutated cells. Gene expression analysis showed 18 dysregulated genes associated with the focal adhesion-PI3K-Akt-mTOR-signaling correlated in KRAS mutant cell lines. Moreover, mTOR overexpression in KRAS mutant H292 cells was inhibited after everolimus exposure, and sensitivity to afatinib and allitinib was restored. Conclusions: Our results indicate that allitinib was more effective than afatinib in NSCLC cell lines. KRAS mutations increased aggressive behavior through upregulation of the focal adhesion-PI3K-Akt-mTOR-signaling in NSCLC cells. Significantly, everolimus restored sensibility and improved cytotoxicity of EGFR inhibitors in the KRAS mutant NSCLC cell lines.

Abstract
Cancer development by the human papillomavirus (HPV) infection can occur through the canonical HPV/p53/RB1 pathway mediated by the E2/E6/E7 viral oncoproteins. During the transformation process, HPV inserts its genetic material into host Integration Sites (IS), affecting coding genes and miRNAs. In penile cancer (PeCa) there is limited data on the miRNAs that regulate mRNA targets associated with HPV, such as the TP53 and RB1 genes. Considering the high frequency of HPV infection in PeCa patients in Northeast Brazil, global miRNA expression profiling was performed in high-risk HPV-associated PeCa that presented with TP53 and RB1 mRNA downregulated expression. The miRNA expression profile of 22 PeCa tissue samples and five non-tumor penile tissues showed 507 differentially expressed miRNAs: 494 downregulated and 13 upregulated (let-7a-5p, miR-130a-3p, miR-142-3p, miR-15b-5p miR-16-5p, miR-200c-3p, miR-205-5p, miR-21-5p, miR-223-3p, miR-22-3p, miR-25-3p, miR-31-5p and miR-93-5p), of which 11 were identified to be in HPV16-IS and targeting TP53 and RB1 genes. One hundred and thirty-one and 490 miRNA binding sites were observed for TP53 and RB1, respectively, most of which were in seedless regions. These findings suggest that up-regulation of miRNA expression can directly repress TP53 and RB1 expression by their binding sites in the non-canonical seedless regions.

Abstract
Background The molecular profile of endometrial cancer has become an important tool in determining patient prognosis and their optimal adjuvant treatment. In addition to The Cancer Genome Atlas (TCGA), simpler tools have been developed, such as the Proactive Molecular Risk Classifier for Endometrial Cancer (ProMisE). We attempted to determine a genetic signature to build a recurrence risk score in patients diagnosed with low- and intermediate-risk endometrial cancer. Methods A case-control study was conducted. The eligible patients were women diagnosed with recurrence low- and intermediate-risk endometrial cancer between January 2009 and December 2014 at a single institution; the recurrence patients were matched to two nonrecurrence patients with the same diagnosis by age and surgical staging. Following RNA isolation of 51 cases, 17 recurrence and 34 nonrecurrence patients, the expression profile was determined using the nCounter® PanCancer Pathways Panel, which contains 770 genes. Results The expression profile was successfully characterized in 49/51 (96.1%) cases. We identified 12 genes differentially expressed between the recurrence and nonrecurrence groups. The ROC curve for each gene was generated, and all had AUCs higher than 0.7. After backward stepwise logistic regression, four genes were highlighted: FN1, DUSP4, LEF1, and SMAD9. The recurrence risk score was calculated, leading to a ROC curve of the 4-gene model with an AUC of 0.93, sensitivity of 100%, and specificity of 72.7%. Conclusion We identified a four-gene signature that may be associated with recurrence in patients with low- and intermediate-risk endometrial cancer. This finding suggests a new prognostic factor in this poorly explored group of patients with endometrial cancer.

Abstract
Cell-free DNA is present in different biological fluids and when released by tumor cells may contribute to pro-tumor events such as malignant transformation of cells adjacent to the tumor and metastasis. Thus, this study analyzed the effect of tumor cell-free DNA, isolated from the blood of prostate cancer patients, on non-tumor prostate cell lines (RWPE-1 and PNT-2). To achieve this, we performed cell-free DNA quantification and characterization assays, evaluation of gene and miRNA expression profiling focused on cancer progression and EMT, and metabolomics by mass spectrometry and cellular migration. The results showed that tumor-free cell DNA was able to alter the gene expression of MMP9 and CD44, alter the expression profile of nine miRNAs, and increased the tryptophan consumption and cell migration rates in non-tumor cells. Therefore, tumor cell-free DNA was capable of altering the receptor cell phenotype, triggering events related to malignant transformation in these cells, and can thus be considered a potential target for cancer diagnosis and therapy.

Abstract
BRAF, NRAS and TERT mutations occur in more than 2/3 of melanomas. Its detection in patient's blood, as circulating tumor DNA (ctDNA), represents a possibility for identification and monitoring of metastatic disease. We proposed to standardize a liquid biopsy platform to identify hotspot mutations in BRAF, NRAS and TERT in plasma samples from advanced melanoma patients and investigate whether it was associated to clinical outcome. Firstly, we performed digital polymerase chain reaction using tumor cell lines for validation and determination of limit of detection (LOD) of each assay and screened plasma samples from healthy individuals to determine the limit of blank (LOB). Then, we selected 19 stage III and IV patients and determined the somatic mutations status in tumor tissue and track them in patients' plasma. We established a specific and sensitive methodology with a LOD ranging from 0.13 to 0.37%, and LOB ranging from of 0 to 5.201 copies/reaction. Somatic mutations occurred in 17/19 (89%) patients, of whom seven (41%) had ctDNA detectable their paired plasma. ctDNA detection was associated with shorter progression free survival (p = 0.01). In conclusion, our data support the use of ctDNA as prognosis biomarker, suggesting that patients with detectable levels have an unfavorable outcome.

Abstract
BACKGROUND Oropharyngeal squamous cell carcinomas (OpSCCs) are commonly associated with high rates of treatment failure. OBJECTIVES To evaluate methylation-based markers in plasma from OpSCC patients as emerging tools for accurate/noninvasive follow-up. METHODS Pretreatment formalin-fixed paraffin-embedded (FFPE) biopsies (n = 52) and paired plasma (n = 15) were tested for the methylation of CCNA1, DAPK, CDH8, and TIMP3 by droplet digital PCR (ddPCR). RESULTS Seventy-one percent (37/52) of the biopsies showed methylation of at least one of the evaluated genes and tumor CCNA1 methylation was associated with recurrence-free survival. Methylated circulating tumor DNA (meth-ctDNA) was detected in 11/15 (73.3%) plasma samples; conversely, plasma samples from healthy controls were all negative for DNA methylation (area under the curve = 0.867; 95% confidence interval = 0.720-1.000). Additionally, preliminary results on the detection of meth-ctDNA in plasma collected during follow-up closely matched patient outcome. CONCLUSIONS The results suggest the feasibility of detecting meth-ctDNA in plasma using ddPCR and a possible application on routine setting after further validation.

Abstract
Background Ductal carcinoma in situ is a non-obligate precursor of invasive breast carcinoma and presents a potential risk of over or undertreatment. Finding molecular biomarkers of disease progression could allow for more adequate patient treatment. We aimed to identify potential biomarkers that can predict invasiveness risk. Methods In this epithelial cell-based study archival formalin-fixed paraffin-embedded blocks from six patients diagnosed with invasive lesions (pure invasive ductal carcinoma), six with in-situ lesions (pure ductal carcinoma in situ), six with synchronous lesions (invasive ductal carcinoma with an in-situ component) and three non-neoplastic breast epithelium tissues were analyzed by gene expression profiling of 770 genes, using the nCounter® PanCancer Pathways panel of NanoString Technologies. Results The results showed that in comparison with non-neoplastic tissue the pure ductal carcinoma in situ was one with the most altered gene expression profile. Comparing pure ductal carcinoma in situ and in-situ component six differentially expressed genes were found, three of them (FGF2, GAS1, and SFRP1), play a role in cell invasiveness. Importantly, these genes were also differentially expressed between invasive and noninvasive groups and were negatively regulated in later stages of carcinogenesis. Conclusions We propose these three genes (FGF2, GAS1, and SFRP1) as potential biomarkers of ductal carcinoma in situ progression, suggesting that their downregulation may be involved in the transition of stationary to migrating invasive epithelial cells.

Abstract
Melanin is produced by melanocytes and protects against DNA damage by ultraviolet light. Unfortunately, the melanin protein present in melanoma tumor cells is often co-purified during DNA extraction, and this contamination may inhibit subsequent PCR methods, which directly impacts research applications and the molecular diagnostic tests needed for targeted therapeutics. There are presently no described purification protocols that efficiently remove melanin from genomic DNA. In this study, we compare six different methods for melanin removal from genomic DNA: Agarose Gel Electrophoresis, 1mg Chelex®-100, Chelex®-100 5%, centrifugation, OneStep™ PCR Inhibitor Removal Kit and centrifugation plus OneStep™ PCR Inhibitor Removal Kit. Each comparison was made using 16 formalin-fixed paraffin-embedded (FFPE) and 11 fresh cell line samples. All samples were initially tested using the multiplex PCR reaction for GAPDH gene that generates different sized amplified products: 100, 200, 300 and 400 base pairs, which could be inhibited by the addition of exogenous melanin. Six purification protocols were then applied, and all samples that amplified at least one GAPDH fragment were sequenced to analyze the presence of the BRAF V600E mutation. The efficiencies of amplification decreased for larger sized fragments in all methods. Our comparisons showed that centrifugation combined with the OneStep™ PCR Inhibitor Removal Kit was superior to all other methods for successful BRAF sequencing with 100% (100bp), 75% (200bp), 50% (300bp), and 31.3% (400bp) amplification efficiencies for the different amplicon sizes. In conclusion, this genomic DNA extraction method is highly efficient for successful PCR when tumor samples are contaminated with melanin.

Abstract
Epidermal growth factor (EGF) and its receptor (EGFR) play an important role in lung carcinogenesis. A functional single nucleotide polymorphism (SNP) in EGF promoter region (EGF+61 A>G-rs4444903) has been associated with cancer susceptibility. Yet, in lung cancer, the EGF+61 A>G role is unclear. The aim of this study was to evaluate the risk of lung cancer associated with EGF+61 A>G SNP in the Brazilian population. For that, 669 lung cancer patients and 1104 controls were analyzed. EGF+61 A>G genotype was assessed by PCR-RFLP and TaqMan genotyping assay. Both patients and controls were in Hardy-Weinberg equilibrium. As expected, uni- and multivariate analyses showed that tobacco consumption and age were significant risk factors for lung cancer. The genotype frequencies in lung cancer patients were 27.3% of AA, 47.4% of AG and 25.3% of GG, and for controls were 25.3% of AA, 51.6% of AG and 23.1% of GG. The allele frequencies were 51.1% of A and 48.9% of G for both cases and controls. No significant differences for the three genotypes (AA, AG and GG-codominant model) were observed between cases and controls. We then grouped AG and GG (recessive model) genotypes, as well as AA and AG (dominant model), and again, no significant differences were also found. This is the largest study to explore EGF+61 A>G polymorphism association with lung cancer risk and suggests that this SNP is not a risk factor for lung cancer in the Brazilian population.

Abstract
Abstract
Background: The treatment of early-stage head and neck squamous cell carcinoma (HNSCC) tumors is conducted through a multimodality approach including surgery, radiation, and chemotherapy, with curative rates of approximately 80-90%. However, only 30-50% of patients with locally advanced disease survive more than five years, despite the advances in surgical techniques and the recognized benefits of chemoradiation. In this scenario, improvement in patients' survival requires both early detection as well as the possibility of predicting, at the moment of diagnosis, which patients will benefit from a specific treatment. Tailoring the treatment is of great importance and may help in the management of treatment planning and follow-up, improving survival rates.
Objectives: The aim of the present study was to evaluate SNPs in genes involved in induction chemotherapy with cisplatin and paclitaxel, which are able to predict the response to an organ-preservation protocol based on chemoradiation.
Materials and Methods: For this purpose, we assessed the profile of 3.223 SNPs of 59 HNSCC patients with locally advanced and unresectable tumors undergoing treatment using the IonTorrent plataform.
Results: From 3,223 SPNs, only 323 were present in the study population and 21 SNPs showed a significant association with response to induction chemotherapy and/or concomitance. Regarding induction chemotherapy response, thirteen polymorphisms were statistically associated. The presence of SNPs rs776746 (CYP3A5 gene) (p=0.03), rs1883322 (PPARD gene) (p=0.03), rs10932374 (ERBB4 gene) (p=0.03), and rs2230806 (ABCA1 gene) (p=0.04) was associated with a favorable treatment response, whereas the remaining polymorphisms with statistical significance were associated with a lack of therapeutic response. It is interesting to note that the presence of three polymorphisms (rs10509681 (p=0.001), rs1058930 (p=0.03), and rs11572080 (p≤0.001)) in the CYP2C8 gene was associated with treatment resistance, showing the importance of these polymorphisms in the process of chemotherapy resistance. Similarly, polymorphisms rs12415607 (p=0.01), rs4353229 (p=0.02), and rs2227310 (p=0.02) in the CASP7 gene were associated with resistance to chemotherapy.
Conclusion: The results of this study suggest that the evaluation of SNPs could be an important tool for treatment planning and a prognosis predictor for HNSCC patients undergoing organ preservation protocols.

Abstract
Abstract
Lung cancer is a malignancy with high incidence and mortality, being in Brazil the second most common cancer in men and the fourth in women. Epidermal growth factor (EGF) and its receptor (EGFR) play a central role in lung carcinogenesis, once EGF/EGFR interaction activates several intracellular pathways that control cellular growth, proliferation, differentiation, migration, and apoptosis. The association has been described between a single nucleotide polymorphism (SNP) in EGF promoter region (EGF+61 A>G – rs4444903) and cancer susceptibility to distinct tumors, including melanoma, gliomas, gastric cancer, hepatocellular carcinoma, and others. In lung cancer, the results are still scarce and unclear, with different reports showing discrepant results. Therefore, the aim of this study is to evaluate the risk of lung cancer development associated with the EGF+61 A>G SNP in a Brazilian population. For that, 437 lung cancer patients and 1104 controls were included in this study. Following DNA isolation from both tumor (FFPE) and controls (blood), the EGF+61 A>G genotype was assessed by polymerase chain reaction–restriction fragment length polymorphism (PCR-RFLP), and TaqMan Genotyping Assay, respectively. Statistical analysis included chi-square and Mann-Whitney tests, and logistic regression model to estimate Odds Ratios. As expected, uni- and multivariate analyses showed that tobacco consumption (p<0.001; OR=4.6; 95% CI 3.53-6.2 for smokers and p<0.001; OR 1.9; 95% CI 1.48-2.56 for ex-smokers) and age (p<0.001; OR=1.03; 95% CI 1.02-1.04 per year) were important risk factors for lung cancer. The genotype frequencies observed in lung cancer patients were 27.9% of AA, 45.1% of AG, and 20% of GG, and for controls were 25.3% of AA, 51.6% of AG, and 23.1% of GG. The allele frequencies were 51% of A and 49% of G in patients, and 50% of each allele in controls. Hardy-Weinberg equilibrium was estimated among patients and controls and no deviation was found in control group. However, patient's group revealed a p=0.039. No significant differences for the three genotypes (AA, AG, and GG) were observed between cases and controls (p=0.064; AG genotype: OR=0.79; 95% CI 0.605-1.033 and GG genotype: OR=1.05; 95% CI 0.78-1.43). We further grouped AG and GG genotypes and compared with the AA genotype, and also did not found significant differences (p=0.3; OR=0.87; 95% CI 0.681-1.120). Moreover, overall survival was calculated for patients considering AG/GG versus AA genotypes, and no significant differences were observed (p=0.21). In conclusion, the present study suggests that EGF+61 A>G polymorphism is not a risk factor for lung cancer in the Brazilian population.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSCC) is the sixth most common type of cancer. The majority of patients present advanced stage disease and has poor survival. Therefore, it is imperative to search for new biomarkers and new alternative and effective treatment options. Most cancer cells rely on aerobic glycolysis to generate energy and metabolic intermediates. This phenotype is a hallmark of cancer, characterized by an increase in glucose consumption and production of high amounts of lactate. Consequently, cancer cells need to up-regulate many proteins and enzymes related with the glycolytic metabolism. Thus, the aim of this study was to characterize metabolic phenotype of oral cavity cancers (OCC) by assessing the expression pattern of monocarboxylate transporters (MCTs) 1, 2 and 4 and other proteins related with the glycolytic phenotype. MATERIAL AND METHODS We evaluated the immunohistochemical expression of MCT1, MCT4, CD147, GLUT1 and CAIX in 135 human samples of OCC and investigated the correlation with clinicopathological parameters and the possible association with prognosis. RESULTS We observed that all proteins analyzed presented significantly higher plasma membrane expression in neoplastic compared to non-neoplastic samples. MCT4 was significantly associated with T-stage and advanced tumoral stage, while CD147 was significantly correlated with histologic differentiation. Interestingly, tumors expressing both MCT1 and MCT4 but negative for MCT2 were associated with shorter overall survival. CONCLUSION Overexpression of MCT1/4, CD147, GLUT1 and CAIX, supports previous findings of metabolic reprograming in OCC, warranting future studies to explore the hyper-glycolytic phenotype of these tumors. Importantly, MCT expression revealed to have a prognostic value in OCC survival.

Abstract
The fruit-flies Drosophila paranaensis and Drosophila mercatorum pararepleta are sibling species belonging to the repleta group. Females of these two species are normally considered to be morphologically indistinguishable while males only differ consistently in the morphology of their genitalia. These species are sympatric throughout a large area of their geographic distribution. In this study, we investigated the degree of morphological divergence between D. paranaensis and D. mercatorum pararepleta based on morphometric analysis of their wings. The ellipse method was used to describe the placement of the longitudinal and transversal wing veins as well as the size of the wing and the shape of its outline. The heritability under laboratory and field conditions was also estimated from the parameters generated. Multivariate analysis showed that wing morphology possessed sufficient differences to discriminate between the two species with a successful classification rate of 95-98% for females and 82-87% for males. The results of the autoclassification were confirmed by a cross-validation test for females (92-96%). Most measurements possessed significant natural heritability (a mean of 0.48 for D. mercatorum and 0.88 for D. paranaensis), indicating that the variation observed was related to differences in genes acting additively. The principal difference between the two species was in the placement of the posterior transverse wing vein. However, the pattern of morphological variation in the wings of both species was similar, possibly because of shared restrictions in wing development pathways.
