Natural flavonoid formononetin (FN) has anticancer effects, but the hydrophobic structure, characteristics of the short half-life in vivo, limiting its clinical wide-ranging application. In this study, FN loaded Pluronic (PF)@folic acid (FA) micelles (FN-PF@FA), were prepared to improve the solubility, bioavailability and targeting. FA coupling PF was prepared by carbodiimide crosslinker chemical method, FN-PF@FA micelles were prepared by modified film hydration method, and compared the antitumor activity of FN loaded micelles with free FN In Vitro. The spherical smooth surface of FN-PF@FA micelles had smaller particle size (112.3±5.3 nm), high encapsulation efficiency (86.14±2.68%), high negative zeta potential (-25.8±0.57 mV), low critical concentration CMC (0.03 mg/mL), and better sustained release profile. In addition, FN-PF@FA micelles have a positive targeting effect on oral squamous cell carcinoma cells (SCC3). In 48 hours, the growth inhibition of 50% (GI50) was 28.6±1.2 μg/mL for FN and 17.4±0.78 μg/mL for FN-PF, the dose dropped by nearly 38.46%. In addition, the GI50 value of FN-PF@FA was 9.5±0.3 μg/mL, 66.43% lower than FN and 44.83% lower than FN-PF. Furthermore, the laser scanning confocal microscopy revealed that the conjugation of FA significantly improves the active targeting ability of micelles. FN-PF@FA micelles have the potential to target the release of anticancer drugs with higher bioavailability, further provides a new avenue for the application of traditional Chinese medicine extract in oral malignant tumor.

AbstractOral squamous cell carcinoma (OSCC) is the most common oral cancer. The molecular mechanisms of this disease are not fully understood. Our previous studies confirmed that dysregulated function of long non-coding RNA (lncRNA) AC007271.3 was associated with a poor prognosis and overexpression of AC007271.3 promoted cell proliferation, migration, invasion, and inhibited cell apoptosis in vitro, and promoted tumor growth in vivo. However, the underlying mechanisms of AC007271.3 dysregulation remained obscure. In this study, our investigation showed that AC007271.3 functioned as competing endogenous RNA by binding to miR-125b-2-3p and by destabilizing primary miR-125b-2, resulted in the upregulating expression of Slug, which is a direct target of miR-125b-2-3p. Slug also inhibited the expression of E-cadherin but N-cadherin, vimentin, and β-catenin had no obvious change. The expression of AC007271.3 was promoted by the canonical nuclear factor-κB (NF-κB) pathway. Taken together, these results suggested that the classical NF-κB pathway-activated AC007271.3 regulates EMT by miR-125b-2-3p/Slug/E-cadherin axis to promote the development of OSCC, implicating it as a novel potential target for therapeutic intervention in this disease.

Mesenchymal Transition

Oral squamous cell carcinoma, one of the most prevalent cancer types in the world, has been confirmed under the influence of a key circadian gene, PER2, whose role has been identified in the development of some other types of cancers. However, the mechanism through which PER2 regulates the progress of OSCC remains largely unknown. In this study, we showed that besides the abnormal expression and subcellular localization of PER2 observed in OSCC tissues and cells as expected, these anomalous changes also existed in the adjacent noncancerous tissues, which was a novel finding in our research. The phase of PER2 rhythmic expression pattern in OSCC cells was later than that in oral keratinocytes in the protein level. In addition, we demonstrated that PER2 played as a resistant factor in the development of OSCC by upregulating TP53 and inhibiting epithelial-mesenchymal transition in vitro and in vivo. Taken together, our results identified that the development of OSCC is closely associated with PER2, the aberrant expression and subcellular localization of which facilitates the malignant progress.

Underlying Mechanisms

Abstract Resistance towards chemotherapy is a common complication in treatment of oral cancers, which leads to treatment failure and poor outcome. In recent years, a growing body of evidence has shown that tumour hypoxia significantly contributes to chemoresistance. Metformin, a widely used oral hypoglycaemic drug, can reportedly potentiate the efficacy of chemotherapeutic drugs in various cancers; however, the underlying mechanisms are intricate and have not been fully understood. In this study, we explored the role of metformin in chemosensitivity of oral squamous cell carcinoma cells (OSCC) to cisplatin both in vitro and in vivo, and attempted to elucidate its possible underlying mechanisms. Encouragingly, we found that metformin synergistically enhanced cisplatin cytotoxicity and reversed the chemoresistance to certain extent. This mechanism could likely be related with inhibition of the NF-κB/HIF-1α signal axis and lead to the downregulation of hypoxia-regulated genes products. Therefore, metformin could serve as a chemosensitiser for cisplatin-based regimens for OSCC, thereby providing a theoretical basis for future use in the treatment of oral cancers.
