Leveraging the observed sensitivity of muscle cells to atorvastatin in clinical settings and utilizing untargeted metabolomic analysis of atorvastatin-treated RD rhabdomyosarcoma cells, we identified reduced levels of aminoadipic acid, an intermediate in lysine catabolism...However, we demonstrated that it is catabolically cleaved to p-nitroanilide, with this molecule driving the cytotoxic activity observed in our experiments. Although lysine metabolism was not fully suppressed by lysine-p-nitroanilide, these findings provide valuable insights for developing novel therapies for rhabdomyosarcoma.
Fusion cells accumulated abundant intracellular lipid droplets and were highly sensitive to simvastatin treatment in vitro and in vivo. Together, this study uncovered that CBX3-SNX10-ANO6 signaling facilitates generation of an aggressive tumor-LAM fusion cell subpopulation that promotes metastasis, revealing an alternative metastatic mechanism and exposing putative therapeutic vulnerabilities. Single-cell transcriptomic profiling combined with functional and clinical validation identifies fusion of tumor cells and lipid-associated macrophages mediated by the CBX3-SNX10-ANO6 axis as a potentially targetable mechanism driving cancer metastasis.
Moreover, we identified simvastatin as a potent inhibitor of CDT1, effectively inhibiting CDT1-mediated centrosome amplification and PGCC formation. In summary, our findings reveal a critical role for CDT1 in driving centrosome amplification and PGCC formation through activation of the PLK4/SASS6 axis, which subsequently contributes to therapeutic resistance and malignant progression.

PPH reverses PTX resistance by targeting cholesterol-lipid rafts to inhibit multiple ABC transporters. This offers a safer adjuvant for PTX-based breast cancer therapy and a translational framework for other drug-resistant malignancies.

The RT-qPCR results of zebrafish verified that Pitavastatin inhibited the expression of HMGCR, while Cabazitaxel inhibited the expression of TUBB1. Our study suggested that Pitavastatin has therapeutic effects on OA, while Cabazitaxel increases the risk of OA.
P2/3, N=177, Terminated, Universitaire Ziekenhuizen KU Leuven | Recruiting --> Terminated; Due to the university's termination of its contract with the online questionnaire platform, we decided to discontinue the study before reaching the anticipated sample size.
Loss of p53 function is strongly associated with venetoclax resistance, and adding venetoclax to 5-azacitidine provides no overall survival benefit in TP53 -mutant AML. The pro-apoptotic actions of pitavastatin depend on depletion of geranylgeranyl pyrophosphate (GGPP) and can be recapitulated by inhibiting GGPP synthase or geranylgeranyltransferase-1 enzymes. These results provide a mechanistic rationale for adding pitavastatin to AML regimens to prevent or overcome venetoclax resistance.
