Deciphering Macrophage and Monocyte Code to Stratify Human Breast Cancer Patients

Area of Science:

• Oncology
• Immunology
• Genomics

Background:

• Tumor-associated macrophages (TAMs) play a crucial role in cancer progression.
• Understanding the transcriptional changes in TAMs induced by different cancers is vital for developing new diagnostic and prognostic tools.

Purpose of the Study:

• To analyze the transcriptional profile of monocytes and macrophages influenced by human breast and endometrial cancers.
• To identify novel biomarkers within TAMs for breast cancer patient stratification and prognosis.

Main Methods:

• Transcriptional profiling of monocytes and macrophages from cancer patients.
• Bioinformatic analysis to identify differentially expressed genes.
• Validation of potential biomarkers in relevant cancer models.

Main Results:

• Human breast and endometrial cancers imprint distinct transcriptional profiles on monocytes and macrophages.
• SIGLEC1 and CCL8 were identified as significantly upregulated in TAMs associated with breast cancer.
• These biomarkers showed potential for distinguishing between different stages or subtypes of breast cancer.

Conclusions:

• SIGLEC1 and CCL8 are proposed as novel biomarkers for TAMs in breast cancer.
• These biomarkers may aid in patient stratification and prognosis, offering new avenues for personalized cancer therapy.
