- Endometrial cancer(EC) is increasing worldwide, but its molecular mechanisms remain unclear. This study explored whether RBM15B-mediated m6A modification of FOXM1 promotes EC progression through the AURKA/TPX2 axis and epithelial-mesenchymal transition(EMT). Bioinformatics analyses assessed FOXM1 expression and prognosis in EC. RNA pull-down, MeRIP-PCR, dot blot, and RNA stability assays examined m6A regulation. Colony formation, Transwell, wound healing, and tumor sphere assays evaluated malignant behaviors. FOXM1 was significantly upregulated in EC and associated with unfavorable prognosis. Functional assays showed that FOXM1 enhanced proliferation, migration, invasion, and stemness of EC cells. Mechanistically, RBM15B increased m6A modification of FOXM1 mRNA and promoted expression. RBM15B knockdown inhibited malignant phenotypes and reduced activation of the downstream AURKA/TPX2 pathway. RBM15B-mediated m6A methylation stabilizes FOXM1 expression, activates the AURKA/TPX2 axis, and promotes EMT and EC progression. Targeting the RBM15B/FOXM1/AURKA/TPX2 pathway may offer therapeutic potential. - Source: PubMed

Zhang LijingWu Ping - Centrosomes are key microtubule-organizing centers required for accurate spindle assembly and chromosome segregation, and their dysfunction in cancer creates therapeutic vulnerabilities. Prior work identified a synthetic lethal interaction between TRIM37 overexpression and Polo-like kinase 4 inhibition (PLK4i) in 17q23-amplified tumors, motivating the clinical development of centrosome-depleting PLK4 inhibitors. However, the broader determinants of sensitivity and resistance to PLK4 inhibition remain poorly defined. Using genome-wide CRISPR-Cas9 screening, we identify multiple genetic suppressors of sensitivity to centrosome depletion, including loss of as a general escape mechanism, mediated by enhanced activation of Aurora kinase A (AURKA) on the spindle. This process requires NuMA, which scaffolds robust acentrosomal spindle assembly, and operates independently of the TRIM37-regulated pathway that restores pericentriolar material (PCM) foci to reconstitute microtubule-organizing center activity. We further show that centrosome depletion creates a dependence on the AURKA-TPX2 axis for spindle assembly, such that modulation of this pathway shapes cellular responses to PLK4 inhibition. Loss of PPP6C elevates AURKA activity and confers resistance, whereas disruption of the AURKA-TPX2 axis sensitizes cells to centrosome depletion. Together, these findings reveal how centrosome depletion rewires mitotic organization, rendering cells dependent on distinct adaptive spindle assembly pathways. - Source: PubMed

Yeow Zhong YChang Fang-ChiXu Lance YHolland Andrew J - Pancreatic cancer is a highly aggressive malignancy with a 5-year relative survival rate of only 13%. Current treatment options have limited efficacy, and mRNA vaccines offer a new direction for its treatment. However, how to accurately identify antigen targets that possess tumor specificity, functional relevance, and immunogenicity remains the key bottleneck restricting the clinical translation of mRNA vaccines for pancreatic cancer. Recent clinical studies have advanced KRAS mutant vaccines and personalized neoantigen mRNA vaccines, yet most rely on single antigens or highly individualized designs, limiting scalability and broader clinical applicability. In this systematic review, we integrated evidence from public databases and experimental studies to identify and evaluate 16 potential pancreatic cancer mRNA vaccine antigens (ADAM9, WNT7A, TMOD3, MET, EFNB2, TPX2, AGPS, OSBPL9, KDM5A, NRAS, SCP-1, GAGE, RAB5A, ANO6, CHMP2B, and PAK2). All candidates were initially selected based on aberrant tumor expression and further prioritized using stratification strategies incorporating antigen-presenting cell infiltration, immune-related cell death pathways such as ferroptosis and pyroptosis, and functional relevance to tumor progression. ADAM9 and PAK2 showed high expression in pancreatic cancer and strong associations with tumor proliferation, invasion, and immune regulation. SCP-1 and GAGE, as cancer-testis antigens, exhibited high tumor specificity and immunogenic potential. In addition, KDM5A and ANO6 may enhance antitumor efficacy through modulation of ferroptosis or pyroptosis. Nevertheless, several candidates remain constrained by normal tissue expression or limited mechanistic evidence. This review provides a stratified framework for antigen prioritization and highlights key challenges in pancreatic cancer mRNA vaccine development, offering guidance for future multi-antigen vaccine design and translational immunotherapy. - Source: PubMed

Zhu JianfuHe AiminZhang YujingHuang BingZhang JunliWang YingQin JingxiaoZhang Zhaohui - Accurate chromosome segregation requires dynamic kinetochore-microtubule attachments that, under the regulation of Aurora family kinases, biorient and align replicated chromosomes. In , Aurora A acts with the TPX2-related activator TPXL-1 to regulate these attachments and control spindle length. We show that, in addition to prominent spindle pole localization, TPXL-1-AurA has a chromatin-associated pool positioned between the sister kinetochores. Structural modeling and biochemical analysis support TPXL-1 directly recognizing the nucleosome acidic patch via an arginine anchor. Disrupting this interaction selectively removed chromatin-bound TPXL-1-AurA and caused chromosome missegregation, whereas elevation of the chromatin pool disrupted chromosome alignment. These opposing perturbations inversely affected kinetochore recruitment of the microtubule-binding Ska complex. These results support spatially distinct TPXL-1-AurA populations acting sequentially, with the spindle pole pool controlling spindle length by switching kinetochores out of a depolymerization-coupled state, and the chromatin pool controlling attachment stabilization to ensure biorientation prior to anaphase. - Source: PubMed
