Chemokines driven ovarian cancer progression, metastasis and chemoresistance: Potential pharmacological targets for cancer therapy

Ovarian cancer is a leading cause of death among women globally often characterized by poor prognosis and aggressive tumor growth. The therapeutic outcomes of ovarian cancer patients are majorly limited by the development of acquired chemo/radioresistance and the lack of targeted therapies. The tumor microenvironment (TME) comprises a diverse population of cells including adipocytes, fibroblasts, tumor cells, and immune cells which play an imperative role in promoting tumor growth, invasion, and malignant phenotypes of cancer cells. The cells present in TME secrete various inflammatory mediators including chemokines and cytokines, which regulate the tumor progression and metastasis. This review article highlights new insights about the general mechanisms associated with chemokines-mediated cell proliferation, inflammation, tumor initiation, progression, metastasis, chemoresistance, and immune evasion in ovarian cancer. We also discuss the microRNAs (miRNAs) regulating the oncogenic potential of chemokines. Overall, this is a comparatively less explored area that could provide important insights into ovarian cancer development and a promising avenue for targeted therapy of ovarian cancer.
