Summary

Despite the advanced therapeutics and enhanced overall survival of breast cancer patients, the mortality rate due to the disease has been increasing over the past few years. Breast cancer tumor genetics and epigenetics research is growing due to advanced genomics and spatial biology technologies and tools. The tumor's genetic/epigenetic makeup cannot only reflect the subtype of breast cancer but also can be correlated to the overall status of the patient's characteristics and lifestyle and any other disease or risk factor. With bioinformatics and big data repositories, we have found specific gene mutations that can correlate with the patients' older or younger age, such as the famous p53 mutation and PIK3CA mutations. Therefore, molecular pathology is having a big impact on the way cancer is diagnosed and treated. Traditionally, hormone receptor biomarkers ER, PR, and HER-2 were the first to be used in any pathology testing; however, more biomarkers for breast cancer were validated using laboratory studies; some got into clinical use; a successful example is the drug Alpelisib small molecule inhibitor that targets the PIK3CA-mutated breast cancer. Olaparib is another drug that was developed to treat patients with metastatic HER2- and BRCA1 or BRCA2 mutated breast cancer tumors. Pembrolizumab is a type of immunotherapy, an anti-programmed death receptor ligand 1 (PD-1) monoclonal antibody; PD1/PDL1 inhibitors were used in the treatment of triple-negative breast cancer TNBC and showed better survival and response to chemotherapy. This issue will focus on all the up-to-date studies that show advanced research using the newest genetic and epigenetic biomarkers to advance the choice of breast cancer drug targets. The issue will open to original research articles and reviews involving translational and clinical cancer research around but not limited to the following topics: 

Aberrant Sialic Acid Expression and Its Role In Regulating Metastasis in Breast Cancer

Epigenetic Biomarkers Regulating Metastasis in Breast Cancer

Contemporaneous Perioperative Inflammatory and Angiogenic Cytokine Profiles of Surgical Breast Cancer Patients: Clinical Implications.

    Abstract Background: Breast cancer still stands to be the foremost contributor to cancer-related incidence and mortality in women globally accounting for about 14% of all female cancer-related deaths worldwide. This research seeks to illustrate the mechanisms and clinical findings of natural products against breast cancer treatment. Methodology: Required data for this review article was retrieved employing several readily obtainable search databases, including Web of Science® (Thomson Reuters, USA), PubMed® (U.S. National Library of Medicine, USA), and SciVerse Scopus® (Elsevier Properties S.A., USA), taking into consideration certain search terms like “breast cancer,” “natural products against breast cancer,” and “Clinically… More >

    Abstract Objectives: While programmed cell death 1 (PD-1) inhibitors have improved cancer treatment, the function and mechanisms of programmed cell death ligand 1 (PD-L1), particularly when expressed by cancer cells, remain unclear. This study aims to explore the role of PD-L1 within breast cancer cells and identify key targets for future immunotherapy. Methods: RNA-seq was performed on breast cancer cells with silenced PD-L1 to screen for differentially expressed genes, followed by bioinformatics analysis. Clinical specimens from breast cancer patients undergoing primary surgery without preoperative treatment were collected, along with in vitro analysis to validate the potential mechanism.

    Abstract Objectives: Deubiquitinase OTUB2 plays a critical role in the progression of various tumors. However, its specific role in triple-negative breast cancer (TNBC) remains unclear. This study aims to elucidate the biological function of OTUB2 in TNBC and uncover the underlying mechanisms. Methods: First, we found that the expression of OTUB2 was upregulated in TNBC by bioinformatics analysis, we then validated its expression in TNBC tissues and cells using immunohistochemistry (IHC) and qPCR and plotted the survival curves by Kaplan-Meier method. Gene set enrichment analysis (GSEA) suggested that OTUB2 may be involved in tumor proliferation and metastasis.… More >
