AI Article Synopsis

  • This study investigates the role of chemokines and their receptors, specifically CCR7 and ACKR4, in breast cancer development and metastasis, looking at their expression in both metastatic and non-metastatic tissue.
  • Researchers used RT-PCR to analyze these receptors in breast cancer samples and ELISA to measure CCL21 levels in the serum, comparing findings to healthy controls.
  • The results show higher levels of CCR7 and CCL21 in metastatic cases, while ACKR4 is more expressed in non-metastatic cases, suggesting that targeting these chemokine receptors could potentially improve treatment outcomes and cancer prognosis.

Article Abstract

Aims: Breast cancer is the most severe malignant tumor in women. Chemokines and their receptors appear to be implicated in tumorigenesis and metastatic pattern. Also the scavenger atypical chemokine receptors are emerging as crucial regulators for the availability of chemokines. Therefore the aim of the present study is to evaluate the expression of CCR7, ACKR4 and their ligand; CCL21 in human breast cancer.

Main Methods: In this study, RT-PCR was done to detect the expression of CCR7 and ACKR4 in 50 non-metastatic and 30 metastatic breast cancer tissue. Also CCL21 level in the serum of study group was detected by ELISA. The expression of all markers is compared to 80 control healthy individual.

Key Findings: Our results revealed the increase in expression of CCR7 and CCL21 level in metastatic group compared to non-metastatic and control groups while ACKR4 expression is significantly increased in breast tissues of non-metastatic patients compared to both control and metastatic groups. Also there was significant positive correlation between CCR7 expression and CCL21 level in cancer patients and significant negative correlation between ACKR4 and both CCR-7 and CCL21 in both non-metastatic and metastatic cancer groups.

Significance: Thus, it might be elucidating that ACKR4 and CCR7 could be a novel target for tumor therapy as targeting the chemokine-receptors axis might represent a powerful tool to prevent infiltration and metastasis and consequently improve cancer prognosis and treatment.

Lysyl oxidase (LOX), a copper-containing secretory oxidase, plays a key role in the regulation of extracellular stiffness through cross-linking with collagen and elastin. Among the LOX family of enzymes, LOX-like 4 (LOXL4) exhibits pro-tumor and anti-tumor properties; therefore, the functional role of LOXL4 in tumor progression is still under investigation. Here, we first determined that transforming growth factor-β1 (TGF-β1) significantly decreased LOXL4 expression in human breast cancer MDA-MB-231 cells, which suggested that decreased LOXL4 may participate in tumor progression.

Urotropine, an antibacterial agent to treat urinary tract bacterial infections, can be also considered as a repurposed drug with formaldehyde-mediated anticancer activity. Recently, we have synthesized urotropine surface modified iron oxide nanoparticles (URO@FeO NPs) with improved colloidal stability and limited cytotoxicity against human fibroblasts. In the present study, we have investigated URO@FeO NP-mediated responses in a panel of forty phenotypically different breast cancer cell lines along with three non-cancerous corresponding cell lines.

Breast cancer is the most commonly diagnosed type of cancer and the leading cause of cancer-related death in women worldwide. Highly targeted therapies have been developed for different subtypes of breast cancer, including hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-positive breast cancer. However, triple-negative breast cancer (TNBC) and metastatic breast cancer disease are primarily treated with chemotherapy, which improves disease-free and overall survival, but does not offer a curative solution for these aggressive forms of breast cancer.

Nowadays, chemotherapy and immunotherapy remain the major treatment strategies for Triple-Negative Breast Cancer (TNBC). Identifying biomarkers to pre-select and subclassify TNBC patients with distinct chemotherapy responses is essential. In the current study, we performed an unbiased Reverse Phase Protein Array (RPPA) on TNBC cells treated with chemotherapy compounds and found a leading significant increase of phosphor-AURKA/B/C, AURKA, AURKB, and PLK1, which fall into the mitotic kinase group.

The aim of the study is to analyze the relationship between personality traits of women with hereditary predisposition to breast/ovarian cancer and their obstetric history and cancer-preventive behaviors. A total of 357 women, participants of 'The National Program for Families With Genetic/Familial High Risk for Cancer', were included in the study. The Neo Five-Factor Inventory (NEO-FFI) and a standardized original questionnaire designed for the purpose of the study were used.
