| description | Abstract Objective TWIST1 is known to promote glycolysis and contribute to pancreatic cancer development; however, its underlying mechanisms remain poorly understood. This study aims to elucidate the molecular mechanisms by which TWIST1 influences aerobic glycolysis in pancreatic ductal adenocarcinoma (PDAC). Methods The expression levels of TWIST1, MMP9, MT1-MMP, and FDX1 in clinical tissues and cancer cell lines were assessed using quantitative reverse transcription PCR (QRT-PCR). Cell treatments with Elesclomol-Cu and 2-deoxyglucose (2DG) were conducted. Immunofluorescence staining and immunoprecipitation analyses were performed to investigate the binding relationship between TWIST1 and HK2. Colony formation and Transwell assays were utilized to evaluate the effects of TWIST1 on cell proliferation, migration, and invasion. Western blotting was employed to detect proteins related to cuproptosis and apoptosis, while ubiquitination assays assessed TWIST1's regulation of HK2 ubiquitination. Results TWIST1 expression was significantly elevated in PDAC tissues, and over-expression of TWIST1 in PDAC cells enhanced colony formation and cell proliferation. Notably, HK2 levels were markedly higher in pancreatic cancer tissues compared to adjacent normal tissues. TWIST1 was found to directly bind and interact with HK2, showing co-localization in the cytoplasm of PDAC cells. Furthermore, TWIST1 was shown to stabilize HK2 by inhibiting its ubiquitin-mediated degradation. Knockdown of TWIST1 or HK2 enhanced the inhibitory effects of 2DG on cell migration and invasion. Treatment with Elesclomol-Cu and 2DG significantly reduced the expression of the cuproptosis-related factor FDX1 with no impact on other cell death factors. Conclusion This study demonstrates that TWIST1 regulates the ubiquitination and degradation of HK2, thereby promoting glycolysis-induced cuproptosis and facilitating pancreatic cancer invasion and metastasis. Understanding the underlying mechanisms of PDAC, including the regulation of key proteins such as HK2 by TWIST1, is crucial for developing more effective treatment strategies. Findings highlight the importance of targeting these molecular pathways, which could lead to improved diagnostic and therapeutic approaches, ultimately enhancing patient outcomes and prognosis. |
