Human papillomavirus (HPV) infections are associated with cervical cancer and other anogenital cancers. Despite progresses in HPV vaccination and screening, these cancers still show high incidence and mortality, requiring improved prognostic markers and tailored therapies. This review addresses the role of Matrix metalloproteinases (MMPs) in HPV-induced cancers and the modulation of MMP expression by HPV oncoproteins. Scientific literature indexed in PubMed and ScienceDirect about Human papillomavirus modulates matrix metalloproteinases was retrieved and critically analyzed, to obtain an overview of expression patterns and their implications for carcinogenesis and patient prognosis. Matrix metalloproteinases such as MMP1, MMP9 and MMP13 have been associated with patient prognosis in HPV-induced cancers and play a major role in the degradation of the extracellular matrix, tumor invasion and metastasis. The HPV E2 and E7 oncoproteins regulate MMP expression via AKT, MEK/ERK and AP-1 signaling among other mechanisms. Increased expression of MMPs is associated with cancer progression and poor prognosis in multiple HPV-induced cancers, suggesting their potential use as prognostic markers. The identification of specific signaling pathways that mediate MMP regulation by HPV is essential for developing efficient new cancer therapies.
