Epigenetic alterations of tumor suppressor genes (TSG) involved in the onset and progression of Breast Cancer (BC) may serve as biomarkers for early detection and prediction of disease prognosis. We have herein tried to determine the methylation status of TSG, in our 50 BC patients and their association with clinicopathological parameters. The methylation status of the gene in fresh tissue samples from 50 patients with BC was assessed by methylation-specific polymerase chain reaction (MS-PCR). The mean age of BC patients was 49.30 ± 9.75 years. Of 50 BC samples tested, 21 (42%) had methylated gene. gene hypermethylation was significantly associated with age ≤ 50 years, premenopausal status and advanced BC stage. Multivariate analysis revealed a strong association between advanced BC stage (Stage III and Stage IV) and hypermethylation (P = 0.008, RR = 5.996, 95% CI = 1.581-22.739). methylation was significantly associated with Triple Negative BC (TNBC) (P = 0.045, OR = 4.181, 95% CI = 1.030-16.981). These findings indicate that hypermethylation frequently occurs in BC. Hypermethylation of in young, premenopausal, TNBC and with advance stage in BC patients suggests its association with aggressive BC.

Background: The online nature of decision aids (DAs) and related e-tools supporting women's decision-making regarding breast cancer screening (BCS) through mammography may facilitate broader access, making them a valuable addition to BCS programs.

Objective: This systematic review and meta-analysis aims to evaluate the scientific evidence on the impacts of these e-tools and to provide a comprehensive assessment of the factors associated with their increased utility and efficacy.

Methods: We followed the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and conducted a search of MEDLINE, PsycINFO, Embase, CINAHL, and Web of Science databases from August 2010 to April 2023.

Mammography is one of the main methods available for breast cancer screening in Brazil. However, differences in timely access and performance of the exam can be highlighted based on social determinants of health, considered relevant due to their influence on the health situation of a population. Thus, the present study aimed to identify the social determinants of health associated with access to and performance of mammography in Brazilian women.

This article aims to identify the relationship between material deprivation and mortality from breast, cervical, and prostate neoplasms in the Brazilian adult population and the relationship between ethnicity/skin color and material deprivation. This cross-sectional ecological study calculated the mean mortality rate per 100,000 inhabitants, and deaths were standardized by age and gender and redistributed per to ill-defined causes, stratified by age group and ethnicity/skin color. We applied the Negative Binomial model, containing the interaction between ethnicity/skin color and the Brazilian Deprivation Index (IBP).

Pathway analysis plays a critical role in bioinformatics, enabling researchers to identify biological pathways associated with various conditions by analyzing gene expression data. However, the rise of large, multi-center datasets has highlighted limitations in traditional methods like Over-Representation Analysis (ORA) and Functional Class Scoring (FCS), which struggle with low signal-to-noise ratios (SNR) and large sample sizes. To tackle these challenges, we use a deep learning-based classification method, Gene PointNet, and a novel $P$-value computation approach leveraging the confusion matrix to address pathway analysis tasks.

BRCA1 deficiency is observed in approximately 25% of triple-negative breast cancer (TNBC). BRCA1, a key player of homologous recombination (HR) repair, is also involved in stalled DNA replication fork protection and repair. Here, we investigated the sensitivity of BRCA1-deficient TNBC models to the frequently used replication chain terminator gemcitabine, which does not directly induce DNA breaks.
