Abstract The survival of cancer cells after detaching from the extracellular matrix (ECM) is essential for metastatic cascade. programmed cell death detachment known as anoikis, acting a metastasis barrier. However, most aggressive escape anoikis and other patterns to initiate This study revealed role migration-inducing protein (CEMIP) in autophagy modulation resistance during ECM detachment. CEMIP amplification resulted protective induction via mechanism dependent on dissociation B-cell...

Abstract Recent research has shown that ferroptosis, the iron-dependent accumulation of lipid peroxides leads to cell death, suppresses cancer metastasis. However, role ferroptosis in prostate metastasis not been completely elucidated. In current study, we identified essential serum/glucocorticoid regulated kinase 2 (SGK2) promoting by inhibiting ferroptosis. We found expression SGK2 was higher metastatic and predicted poor clinical outcomes. knockdown inhibited capacity cells vivo vitro,...

Gastrodin is the main bioactive ingredient of a famous Chinese herb Rhizoma Gastrodiae. Many studies have reported that gastrodin has antioxidative and neuroprotective effects, although its effect on longevity mechanism neuroprotection not been well studied. Here, we use Drosophila melanogaster as model to investigate effects gastrodin. significantly extended lifespan, increased climbing ability, enhanced resistance oxidative stress, enzyme activities superoxide dismutase (SOD) catalase...

Cells detached from the extracellular matrix (ECM) can trigger different modes of cell death, and survival ECM-detached cells is one prerequisites for metastatic cascade. Ferroptosis, a form iron-dependent programmed has recently been found to be involved in matrix-detached cancer cells. However, molecular mechanisms by which escape ferroptosis are not fully understood. Here, we observed that migration-inducing protein (CEMIP) upregulation facilitates resistance during ECM detachment...

Acquisition of the chemoresistance to docetaxel (DTX), a microtubule-targeting agent, has been huge obstacle in treatment for metastatic castration-resistant prostate cancer (mCRPC). Recently, strategies targeting mitosis error correction mechanism including chromosomal passenger complex (CPC) were reported reverse resistance anticancer agents. Meanwhile, accumulating evidence indicated important roles circRNAs DTX (PCa). However, whether could regulate chemosensitivity by affecting remains...
