Cervical cancer (CC) is one of the most frequent cancers in women worldwide. The epithelial-mesenchymal transition (EMT) and the extracellular release of TGF-β are phenomena typically associated with different tumorigenic processes, including tumour cell proliferation and metastatization. Specific human microRNAs (miRNAs; miRs) involved in these tumorigenic processes have been identified, becoming important diagnostic and prognostic markers, and even potential therapeutic targets. In parallel, different studies have also shown that plant miRNAs can mediate a cross-kingdom regulation (CKR) of mammalian genes and modulate host's gene expression under pathological conditions, restoring the regulatory activity of endogenous miRNAs lost in cancer. In our previous studies, the miRNome from Moringa oleifera Lam. (henceforth moringa or mol) has been sequenced, showing the presence of several conserved miRNAs in the plant kingdom, whose ability to differentially regulate proliferation and apoptosis in healthy and cancer cells has been demonstrated. Furthermore, the effects of mol-miR treatment on tumorigenesis and EMT have been proved in liver tumour cells. According to these premises, we here investigated the proteomic profile of CC-derived HeLa cells exposed to a mol-miRNA pool, demonstrating the down-representation of specific factors involved in tumorigenesis. The treatment with plant miRs was able to modulate proteins involved in several biological processes linked to EMT. Furthermore, it reduced the expression of TGF-β and significantly inhibited cell motility, as observed following Scratch test and cell viability measurements, with a significant increase of apoptotic events. In conclusion, our results suggest and pave the way for the development of new potential therapeutic approaches based on CKR mediated by plant miRNAs for contrasting human cervical cancer, even in the form of adjuvants to classic treatments for limiting their side effects. |
