ID09, A Newly-Designed Tubulin Inhibitor, Regulating the Proliferation, Migration, EMT Process and Apoptosis of Oral Squamous Cell Carcinoma.

ABSTRACT: Microtubules, a major target in oral squamous cell carcinoma (OSCC) chemotherapy, contribute to multiple malignant biological behaviors, including proliferation, migration, and epithelial-mesenchymal transition (EMT). Surpassing traditional tubulin inhibitors, ID09 emerges with brilliant solubility, photostability, and drug-sensitivity in multidrug-resistant cells. Its anti-tumor effects have been briefly verified in lung adenocarcinoma and hepatocellular carcinoma. However, whether OSCC is sensitive to ID09 and the potential mechanisms remain ambiguous, which are research purposes this study aimed to achieve. Various approaches were applied, including clone formation assay, flow cytometry, wound healing assay, Transwell assay, cell counting kit-8 assay, Western blot, qRT-PCR, and in vivo experiment. The experimental results revealed that ID09 not only contributed to cell cycle arrest, reduced migration, and reversed EMT, but accelerated mitochondria-initiated apoptosis. Remarkably, Western blot detected diminishment in expression of Mcl-1 due to the deactivation of Ras-Erk pathway, resulting in ID09-induced apoptosis, proliferation and migration suppression, which could be offset by Erk1/2 phosphorylation agonist Ro 67-7476. This study initially explored the essential role Mcl-1 played and the regulatory effect of Ras-Erk pathway in anti-cancer process triggered by tubulin inhibitor, broadening clinical horizon of tubulin inhibitors in oral squamous cell carcinoma chemotherapy application.

Project description:PurposeBreast cancer (BC), with varying histopathology, biology and response to systemic treatment, is the second leading cause of cancer-related mortality. Previous studies have inferred that the expression of mitochondrial ribosomal proteins (MRPs) is possibly related to the occurrence/progression of BC. MRPL13 might be one of the potential MRP candidates that are involved in BC tumorigenesis, but its role in BC has rarely been reported. The purpose of the current study was to evaluate the prognostic significance of MRPL13, as well as to explore its potential biological functions in BC.Materials and methodsA series of bioinformatic and statistical methods were adopted to assess the MRPL13 expression profile, its relationship with clinicopathological characteristics, copy number variation (CNV), impact on clinical outcomes and relevant functions. All the results are analysed by 1097 BC patients collected from The Cancer Genome Atlas (TCGA) dataset and 52 clinical samples for immunohistochemistry (IHC) assay.ResultsThe results demonstrated that the expression of MRPL13 in BC tissues was remarkably elevated than that in normal breast tissues. In addition, the Kaplan-Meier curves and Cox model indicated that patients with high MRPL13 expression were connected to a worse prognosis, heralding the independent prognostic value of this protein in BC. Moreover, an enrichment analysis showed that MRPL13 was mainly involved in cell cycle/division-related, RNA processing (degradation/splicing), MYC targets and the MTORC1 pathways. In addition, RNA interference (RNAi)-mediated MRPL13 silencing remarkedly inhibited proliferation and migration as well as the expression of EMT-related genes of BC cells in vitro. Mechanistically, attenuation of MRPL13 significantly suppressed the phosphorylation of AKT and mTOR, which could be partially abolished by 740Y-P (a PI3K agonist).ConclusionOur results provide evidence for the first time that increased MRPL13 expression correlates with adverse clinicopathological variables and unfavorable clinical outcomes of BC patients. Knockdown of MRPL13 restrains the proliferation and migration potential and EMT process of BC through inhibiting PI3K/AKT/mTOR signaling pathway.
