Objective: Breast cancer is a malignant tumor with high invasion and metastasis. TGF-β1-induced epithelial-mesenchymal transition (EMT) is crucially involved in the growth and metastasis of breast cancer. Wedelolactone (Wed) is extracted from herbal medicine Ecliptae Herba, which is reported to have antineoplastic activity. Here, we aimed to elucidate the efficacy and mechanism of Wed against breast cancer.
Methods: The effects of Wed on migration and invasion of 4T1 were detected. The expression of EMT-related markers was detected by Western blot and qPCR. The 4T1 orthotopic murine breast cancer model was established to evaluate the therapeutic effect of Wed on the growth and metastasis of breast cancer through TGF-β1/Smad pathway.
Results: Wed inhibited the proliferation, migration and invasion of 4T1. It exhibited concentration-dependent inhibition of p-Smad2/3. Wed also reversed the expression of EMT-markers induced by TGF-β1. In addition, Wed suppressed the growth and metastasis of breast cancer in mice. It also affected p-Smad3 expression as well as EMT-related genes, suggesting that its anti-breast cancer effect may be related to the TGF-β1/Smad pathway.
Conclusion: Wed reverses EMT by regulating TGF-β1/Smad pathway, potentially serving as a therapeutic agent for breast cancer. Wed is expected to be a potential drug to inhibit TGF-β1/Smad pathway-related diseases.

Purpose: Male breast cancer is an understudied disease with unique clinicopathological features. This study aims to evaluate the predictive value of the Clinical Treatment Score post-5 years (CTS5) in estimating late recurrence risk in estrogen receptor-positive (ER+) male breast cancer patients.
Methods: This retrospective study includes 65,711 ER+ early male (n = 611) and female (n = 65,100) breast cancer patients from the Surveillance, Epidemiology, and End Results (SEER) database diagnosed between 2010 and 2018.

Background: Risk reducing mastectomy (RRM) is an option for women with pathogenic germline variants in BRCA1 or BRCA2 (BRCA1/2). This study investigates and compares RRM-uptake among Norwegian BRCA1/2 carriers from 2008 to 2021, temporal trends, and incidence of breast cancer (BC) after surgery.
Methods: BRCA1/2 carriers without prior breast or ovarian cancer, tested at Oslo University Hospital between January 1st 2008 and December 31st 2021 were included in the study.

Background: The infiltration of tumor-infiltrating B cells and plasma cells in early-stage breast cancer has been associated with a reduced risk of distant metastasis. However, the influence of B-cell tumor infiltration on overall patient survival remains unclear.
Materials And Methods: This study explored the relationship between an antitumor immune response, measured by a 14-gene B-cell/immunoglobulin (IGG) signature, and mortality risk in 9638 breast cancer patients across three datasets.

Rationale And Objectives: To propose a novel MRI-based hyper-fused radiomic approach to predict pathologic complete response (pCR) to neoadjuvant therapy (NAT) in breast cancer (BC).
Materials And Methods: Pretreatment dynamic contrast-enhanced (DCE) MRI and ultra-multi-b-value (UMB) diffusion-weighted imaging (DWI) data were acquired in BC patients who received NAT followed by surgery at two centers. Hyper-fused radiomic features (RFs) and conventional RFs were extracted from DCE-MRI or UMB-DWI.

For the first time, our study provides a comprehensive examination of the anti-cancer effects of structural isomers of carene in breast cancer cells, specifically focusing on cell cycle inhibition and the induction of apoptosis. We utilized the hydro-distillation method to extract Piper nigrum seed essential oil (PNS-EO) and identified its bioactive components through gas chromatography-mass spectrometry (GC-MS) analysis. A total of 46 bioactive compounds were isolated via hydro-distillation, identified through GC-MS analysis, and validated by co-injection using GC analysis.
