Abstract
Breast cancer represents a health concern worldwide for being the leading cause of cancer-related women's death. The main challenge for breast cancer treatment involves its heterogeneous nature with distinct clinical outcomes. It is clinically categorized into five subtypes: luminal A; luminal B, HER2-positive, luminal-HER, and triple-negative. Despite the significant advances in the past decades, critical issues involving the development of efficient target-specific therapies and overcoming treatment resistance still need to be better addressed. OMICs-based strategies have marked a revolution in cancer biology comprehension in the past two decades. It is a consensus that Next-Generation Sequencing (NGS) is the primary source of this revolution and the development of relevant consortia translating pharmacogenomics into clinical practice. Still, new approaches, such as CRISPR editing and epigenomic sequencing are becoming essential for target and biomarker discoveries. Here, we discuss genomics and epigenomics techniques, how they have been applied in clinical management and to improve therapeutic strategies in breast cancer, as well as the pharmacogenomics translation into the current and upcoming clinical routine.

Abstract
The aim of this study was to evaluate photobiomodulation effects on mRNA relative levels from genes of base excision repair and genomic stabilization in heart tissue from an experimental model of acute lung injury by sepsis. For experimental procedure, animals were randomly assigned to six main groups: (1) control group was animals treated with intraperitoneal saline solution; (2) LASER-10 was animals treated with intraperitoneal saline solution and exposed to an infrared laser at 10 J cm-2; (3) LASER-20 was animals treated with intraperitoneal saline solution and exposed to an infrared laser at 20 J cm-2; (4) acute lung injury (ALI) was animals treated with intraperitoneal LPS (10 mg kg-1); (5) ALI-LASER10 was animals treated with intraperitoneal LPS (10 mg kg-1) and, after 4 h, exposed to an infrared laser at 10 J cm-2 and (6) ALI-LASER20 was animals treated with intraperitoneal LPS (10 mg kg-1) and, after 4 h, exposed to an infrared laser at 20 J cm-2. Irradiation was performed only once and animal euthanasias for analysis of mRNA relative levels by RT-qPCR. Our results showed that there was a reduction of mRNA relative levels from ATM gene and an increase of mRNA relative levels from P53 gene in the heart of animals with ALI when compared to the control group. In addition, there was an increase of mRNA relative levels from OGG1 and APE1 gene in hearts from animals with ALI when compared to the control group. After irradiation, an increase of mRNA relative levels from ATM and OGG1 gene was observed at 20 J cm-2. In conclusion, low-power laser modulates the mRNA relative levels from genes of base excision repair and genomic stabilization in the experimental model of acute lung injury evaluated.

Abstract
Background: Mutations in the fibroblast growth factor receptor 3 (FGFR3) gene are related to skeletal dysplasias (SDs): acondroplasia (ACH), hypochodroplasia (HCH) and type I (TDI) and II (TDII) tanatophoric dysplasias. This study was designed to standardize and implement a high-resolution melting (HRM) technique to identify mutations in patients with these phenotypes. Methods: Initially, FGFR3 gene segments from 84 patients were PCR amplified and subjected to Sanger sequencing. Samples from 29 patients positive for mutations were analyzed by HRM. Results: Twelve of the patients FGFR3 mutations had ACH (six g.16081 G > A, three g.16081 G > C and three g.16081 G > A + g.16002 C > T); thirteen of patients with HCH had FGFR3 mutations (eight g.17333 C > A, five g.17333 C > G and five were negative); and four patients with DTI had FGFR3 mutations (three g.13526 C > T and one g.16051G > T and two patients with DTII (presented mutation g.17852 A > G). When analyzing the four SDs altogether, an overlap of the dissociation curves was observed, making genotyping difficult. When analyzed separately, however, the HRM analysis method proved to be efficient for discriminating among the mutations for each SD type, except for those patients carrying additional polymorphism concomitant to the recurrent mutation. Conclusion: We conclude that for recurrent mutations in the FGFR3 gene, that the HRM technique can be used as a faster, reliable and less expensive genotyping routine for the diagnosis of these pathologies than Sanger sequencing.

Abstract
Hypoxia is an inherent condition of tumors and contributes to cancer development and progression. Hypoxia-inducible factors (HIFs) are the major transcription factors involved in response to low O2 levels, orchestrating the expression of hundreds of genes involved in cancer hallmarks’ acquisition and modulation of epigenetic mechanisms. Epigenetics refers to inheritable mechanisms responsible for regulating gene expression, including genes involved in the hypoxia response, without altering the sequence of DNA bases. The main epigenetic mechanisms are DNA methylation, non-coding RNAs, and histone modifications. These mechanisms are highly influenced by cell microenvironment, such as O2 levels. The balance and interaction between these pathways is essential for homeostasis and is directly linked to cellular metabolism. Some of the major players in the regulation of HIFs, such as prolyl hydroxylases, DNA methylation regulators, and histone modifiers require oxygen as a substrate, or have metabolic intermediates as cofactors, whose levels are altered during hypoxia. Furthermore, during pathological hypoxia, HIFs’ targets as well as alterations in epigenetic patterns impact several pathways linked to tumorigenesis, such as proliferation and apoptosis, among other hallmarks. Therefore, this review aims to elucidate the intricate relationship between hypoxia and epigenetic mechanisms, and its crucial impact on the acquisition of cancer hallmarks.

Abstract
BACKGROUND The targeted induction of reactive oxygen species (ROS) is a developing mechanism for cancer therapy. LQB-118 is a pterocarpanquinone and ROS-inducing agent with proven antineoplastic activity. Here, LQB-118 efficacy and mechanism of activity, were examined in Prostate Cancer (PCa) cell and tumor models. METHODS PC3, LNCaP, and LAPC4 PCa cells were applied. Dicoumarol treatment was used to inhibit quinone reductase activity. N-acetylcysteine (NAC) was applied as a ROS scavenger. ROS production was quantified by H2 DCFDA flow cytometry. LQB-118 treated cells were evaluated for changes in lipid peroxidation, viability, and apoptosis. Treatment-induced gene expression was measured by RT-qPCR and Western Blot. SOD1 knockdown was achieved with siRNA or miRNA mimic transfection. MicroRNA specificity was determined by 3'UTR reporter assay. Oral LQB-118 treatment (10 mg/kg/day) efficacy was determined in athymic male nude mice bearing subcutaneous PC3 xenograft tumors. RESULTS LQB-118 treatment triggered PCa cell death and apoptosis. Therapeutic activity was at least partially dependent upon quinone reduction and ROS generation. LQB-118 treatment caused an increase in cellular ROS and lipid peroxidation. Treated cells exhibited elevated levels of NQO1, Nrf2, and SOD1. The miRNAs miR-206, miR-1, and miR-101 targeted and reduced SOD1 expression. The knockdown of SOD1, by siRNA or miRNA, enhanced LQB-118 cytotoxicity. Orally administered LQB-118 treatment significantly reduced the growth of established PCa xenograft tumors. CONCLUSION LQB-118 is a developing and orally active pterocarpanquinone agent that effectively kills PCa cells through quinone reduction and ROS generation. The inhibition SOD1 expression enhances LQB-118 activity, presumably by impairing the cellular antioxidant response.

Abstract
LLL-3, an anthracene derived compound, has been shown to be a promising therapeutic agent for the treatment of some kinds of cancer such as chronic myeloid leukemia and glioblastoma. However, no data regarding the toxic properties of this compound have yet been described in the literature. The present work aimed to investigate the mutagenic and genotoxic activities of LLL-3 using the TA97, TA98, TA100, TA102 and TA104 Salmonella/microsome strains for the Ames test and the micronucleus assay with the mouse macrophage cell line RAW 264.7. The findings showed that LLL-3, at doses of 0.001, 0.01, 0.1, 1.0 and 10.0 μg/plate, did not induce mutagenic activity in the Salmonella strains used under the conditions tested, and nor did it present genotoxicity in RAW 264.7 cells, at 10.0, 100.0 and 1000.0 μg/mL doses. Moreover, it is important to point out that the mitotic index of the cells decreased after exposure to LLL-3 under the same conditions tested, which may suggest some cytostatic effect, since this compound acts by inhibiting STAT3. Since most drugs used in the treatment of cancer present mutagenic activity as an adverse effect, these results suggest that LLL-3 is a promising drug for cancer therapy.

Abstract
Drug resistance is a major hurdle for successful treatment of breast cancer, the leading cause of deaths in women throughout the world. The FOXM1 transcription factor is a potent oncogene that transcriptionally regulates a wide range of target genes involved in DNA repair, metastasis, cell invasion, and migration. However, little is known about the role of FOXM1 in cell survival and the gene targets involved. Here, we show that FOXM1-overexpressing breast cancer cells display an apoptosis-resistant phenotype, which associates with the upregulation of expression of XIAP and Survivin antiapoptotic genes. Conversely, FOXM1 knockdown results in XIAP and Survivin downregulation as well as decreased binding of FOXM1 to the promoter regions of XIAP and Survivin. Consistently, FOXM1, XIAP, and Survivin expression levels were higher in taxane and anthracycline-resistant cell lines when compared to their sensitive counterparts and could not be downregulated in response to drug treatment. In agreement with our in vitro findings, we found that FOXM1 expression is significantly associated with Survivin and XIAP expression in samples from patients with IIIa stage breast invasive ductal carcinoma. Importantly, patients co-expressing FOXM1, Survivin, and nuclear XIAP had significantly worst overall survival, further confirming the physiological relevance of the regulation of Survivin and XIAP by FOXM1. Together, these findings suggest that the overexpression of FOXM1, XIAP, and Survivin contributes to the development of drug-resistance and is associated with poor clinical outcome in breast cancer patients.

Abstract
Radiotherapy remains a major approach to adjuvant therapy for patients with advanced colorectal cancer, however, the fractionation schedules frequently allow for the repopulation of surviving tumors cells, neoplastic progression, and subsequent metastasis. The aim of the present study was to analyze the transgenerational effects induced by radiation and evaluate whether it could increase the malignant features on the progeny derived from irradiated parental colorectal cancer cells, Caco-2, HT-29, and HCT-116. The progeny of these cells displayed a differential radioresistance as seen by clonogenic and caspase activation assay and had a direct correlation with survivin expression as observed by immunoblotting. Immunofluorescence showed that the most radioresistant progenies had an aberrant morphology, disturbance of the cell-cell adhesion contacts, disorganization of the actin cytoskeleton, and vimentin filaments. Only the progeny derived from intermediary radioresistant cells, HT-29, reduced the E-cadherin expression and overexpressed β-catenin and vimentin with increased cell migration, invasion, and metalloprotease activation as seen by immunoblotting, wound healing, invasion, and metalloprotease activity assay. We also observed that this most aggressive progeny increased the Wnt/β-catenin-dependent TCF/LEF activity and underwent an upregulation of mesenchymal markers and downregulation of E-cadherin, as determined by qRT-PCR. Our results showed that the intermediate radioresistant cells can generate more aggressive cellular progeny with the EMT-like phenotype. The Wnt/β-catenin pathway may constitute an important target for new adjuvant treatment schedules with radiotherapy, with the goal of reducing the migratory and invasive potential of the remaining cells after treatment.

Abstract
PURPOSE Breast cancer treatments can induce important cardiovascular complications. The aim of this study was to evaluate cardiac alterations after irradiation and chemotherapy in an animal model. MATERIAL AND METHODS Wistar rats were divided into three groups: Control, TC+ IR (received chemotherapy and irradiation) and IR (received only irradiation). After 5 months, echocardiography was performed, the animals were euthanized, and the left ventricle was analyzed using light microscopy techniques and Polymerase Chain Reaction (PCR). RESULTS Echocardiography showed decreases in ejection fraction and cardiac output, in TC+ IR group. Both TC+ IR and IR showed reduced intramyocardial vessel-to-cardiomyocyte ratio, increased connective tissue, cardiomyocyte hypertrophy, increased numbers of apoptotic nuclei and increased Bax/Bcl2 expression. We also observed increased Transforming growth factor (TGF) beta 1 mRNA expression in both groups, but type 1 Procollagen expression was increased in TC+ IR group only. CONCLUSIONS The study suggests that the induced cardiac remodelling begins with the reduction of intramyocardial vessels in the left ventricle tissue. The main consequence is the loss of cardiomyocytes through apoptosis, leading to the replacement of healthy tissue by fibrous tissue. It was observed that the damage caused by the combination of irradiation and chemotherapy induced functional alterations that did not occur when the animals were only irradiated.

Abstract
Galanin and its receptors have been shown to be expressed in undifferentiated mouse embryonic stem (ES) cells through transcriptome and proteomic analyses. Although transcriptional regulation of galanin has been extensively studied, the regulatory proteins that mediate galanin expression in mouse ES cells have not yet been determined. Through sequence alignments, we have found a high degree of similarity between mouse and human galanin upstream sequences at -146 bp/+69 bp (proximal region) and -2,408 bp/-2,186 bp (distal region). These regions could be recognized by ES cell nuclear proteins, and EMSA analysis suggests a specific functionality. Analysis of the proximal region (PR) using EMSA and ChIP assays showed that the CREB protein interacts with the galanin promoter both in vitro and in vivo. Additional EMSA analysis revealed that an SP1 consensus site mediated protein-DNA complex formation. Reporter assays showed that CREB is an activator of galanin expression and works cooperatively with SP1. Furthermore, analysis of the distal region (DR) using EMSA assays demonstrated that both HOX-F and PAX 4/6 consensus sites mediated protein-DNA complex formation, and both sites inhibited luciferase activity in reporter assays. These data together suggest that CRE and SP1 act as activators at the basal promoter, while HOX-F and PAX 4/6 act as silencers of transcription. The interplay of these transcription factors (TF) may drive regulated galanin expression in mouse ES cells.
