MetabolomicsTFAM loss induces nuclear actin assembly upon mDia2 malonylation to promote liver cancer metastasis
The mechanisms underlying cancer metastasis remain poorly understood. Here, we report that TFAM deficiency rapidly and stably induced spontaneous lung metastasis in mice with liver cancer. Interestingly, unexpected polymerization of nuclear actin was observed in TFAM-knockdown HCC cells when cytoske...

MetabolomicsSingle-cell lipidomic analysis of the Epithelial-Mesenchymal Transition (EMT) using MALDI-MSI

EMT is a metastasis-promoting process whose heterogeneity has been extensively studied at a gene expression level. EMT also involves reprogramming of lipid metabolism, however there has been little focus on heterogeneity on the lipid level. Here, we use MALDI-MSI to determine the levels of variou...

TranscriptomicsH. pylori G27 HP0518 mutant showed greater motility
Helicobacter pylori is a human gastric pathogen associated with gastric and duodenal ulcers as well as specific gastric cancers. It is well-evidenced that motility is essential for this pathogen to colonize human gastric tissues. We found that the H. pylori G27 HP0518 mutant showed greater motility ...

MetabolomicsObesogenic high-fat diet and MYC cooperate to promote lactate accumulation and tumor microenvironment remodeling in prostate cancer (Murine serum assays)

Cancer cells exhibit metabolic plasticity to meet oncogene-driven dependencies while coping with nutrient availability. A better understanding of how systemic metabolism impacts the accumulation of metabolites that reprogram the tumor microenvironment and drive cancer could facilitate development...

TranscriptomicsPancreatic cancercirculating tumor cells express a cell motility gene signature that predicts survival after surgery.
Most cancer deaths are caused by metastases, which are the end-results of circulating tumor cells (CTC) that detach from the cancer primary and succeed to survive in distant organs. The aim of the present study was to develop a gene signature of CTC and to assess its prognostic relevance after surge...

ProteomicsBistability in the Rac1, PAK and RhoA signalling network is a feature of cell motility.
Dynamic interactions between RhoA and Rac1, members of the Rho small GTPase family, play a vital role in the control of cell migration. Using predictive mathematical modelling and experimental validation in MDA-MB-231 mesenchymal breast cancer cells, we show that Rac1 and RhoA interactions via the P...

TranscriptomicsAn EMT-driven alternative splicing program occurs in human breast cancer and modulates cellular phenotype.
Regulation of cell-cell junction formation and regulation of cell migration were enriched among EMT (Epithelial-Mesenchymal Transition)-associated alternatively splicing events. Our analysis suggested that most EMT-associated alternative splicing events are regulated by one or more members of the RB...

TranscriptomicsNOTCH3 is a master-regulator of motility in neuroblastoma and is essential for cell survival
Migratory embryonal neuroblasts give rise to several tissues, including the sympathetic nervous system (SNS). Neuroblastomas are paediatric tumours of the peripheral SNS with a highly variable prognosis. We observed that high NOTCH3 expression in neuroblastomas correlated with a poor prognosis. Expr...

ProteomicsPhosphatase POPX2 exhibits dual regulatory functions in cancer metastasis
Cancer metastasis is a complex mechanism involving multiple processes. In an earlier study, we reported that the levels of serine/threonine phosphatase POPX2were positively correlated with cancer cell motility through modulating MAPK signaling. Surprisingly, here we found that POPX2 knockdown cells ...
