The different molecular subtypes of breast cancer are associated with variable clinical outcomes and therapeutic responses. Progranulin, a secreted glycoprotein, is involved in regulating cellular growth, migration, and survival. The expression of Progranulin has been reported in several human cancers, including breast cancer, but its role in different molecular subtypes of breast cancer remains unclear.Objective: This study aims to investigate the expression and clinical significance of Progranulin in different molecular subtypes of breast cancer.Methods: We will analyze the expression of Progranulin in tissue samples of breast cancer patients using immunohistochemistry (IHC) and Polymerase Chain Reaction (PCR) techniques. The samples will be classified into different molecular subtypes based on the expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2). The clinicopathological data of patients will be collected and analyzed for correlations with Progranulin expression.Expected Results: We expect to find differential expression of Progranulin in different molecular subtypes of breast cancer. We also expect to find correlations between Progranulin expression and clinicopathological factors such as tumor size, lymph node metastasis, and overall survival.Conclusion: The findings of this study may provide important insights into the molecular mechanisms underlying different subtypes of breast cancer and could have potential clinical implications for the diagnosis and treatment of breast cancer patients.
