MicroRNA-326 (miR-326) was reported to be dysregulated and involved in the progression of multiple cancers. However, the clinical significance, biological role and underlying mechanism of miR-326 in the carcinogenesis of breast cancer are still unclear. In the present study, we showed that miR-326 was down-regulated in human breast cancer tissues and cell lines. Our results also revealed that miR-326 overexpression significantly suppressed breast cancer cell proliferation, migration and invasion, and induced cell cycle arrest at G/G phase. Furthermore, Sex determining region Y-box (SOX) protein 12 (SOX12), a known oncogene, was identified as a direct target of miR-326 by luciferase reporter assay. Moreover, miR-326 expression was inversely correlated with mRNA expression levels in human breast cancer specimens. Overexpression of SOX12 partially rescued the inhibitory effect on cell proliferation, migration and invasion in breast cancer cells caused by miR-326 overexpression. These findings suggested that miR-326 might play a suppressive role in breast cancer, at least in part, by targeting SOX12, rendering miR-326 a promising therapeutic target for breast cancer.

Purpose: Breast cancer remains a significant public health challenge globally, as well as in India, where it is the most frequently diagnosed cancer in females. Significant disparities in incidence, mortality, and access to health care across India's sociodemographically diverse population highlight the need for increased awareness, policy reform, and research.
Design: This review consolidates data from national cancer registries, global cancer databases, and institutional findings from a tertiary care center to examine the epidemiology, clinical challenges, and management gaps specific to India.

ObjectiveTo study the implications of implementing artificial intelligence (AI) as a decision support tool in the Norwegian breast cancer screening program concerning cost-effectiveness and time savings for radiologists.MethodsIn a decision tree model using recent data from AI vendors and the Cancer Registry of Norway, and assuming equal effectiveness of radiologists plus AI compared to standard practice, we simulated costs, effects and radiologist person-years over the next 20 years under different scenarios: 1) Assuming a €1 additional running cost of AI instead of the €3 assumed in the base case, 2) varying the AI-score thresholds for single vs. double readings, 3) varying the consensus and recall rates, and 4) reductions in the interval cancer rate compared to standard practice.

Background: Among childhood cancer survivors, germline rare variants in autosomal dominant cancer susceptibility genes (AD CSGs) could increase subsequent neoplasm (SNs) risks, but risks for rarer SNs and by age at onset are not well understood.
Methods: We pooled the Childhood Cancer Survivor Study and St Jude Lifetime Cohort (median follow-up = 29.7 years, range 7.

MicroRNAs (miRNAs) are critical regulators of gene expression in cancer biology, yet their spatial dynamics within tumor microenvironments (TMEs) remain underexplored due to technical limitations in current spatial transcriptomics (ST) technologies. To address this gap, we present STmiR, a novel XGBoost-based framework for spatially resolved miRNA activity prediction. STmiR integrates bulk RNA-seq data (TCGA and CCLE) with spatial transcriptomics profiles to model nonlinear miRNA-mRNA interactions, achieving high predictive accuracy (Spearman's ρ > 0.

Objective: This study employs integrated network toxicology and molecular docking to investigate the molecular basis underlying 4-nonylphenol (4-NP)-mediated enhancement of breast cancer susceptibility.
Methods: We integrated data from multiple databases, including ChEMBL, STITCH, Swiss Target Prediction, GeneCards, OMIM and TTD. Core compound-disease-associated target genes were identified through Protein-Protein Interaction (PPI) network analysis.
