In this study we investigated the critical role of NOX1 in progression, metastasis and therapeutic sensitivity of HCC, and explored its potential as a therapeutic target. By comprehensive analysis of public databases and validation with in-house clinical specimens, we showed that NOX1 expression was significantly elevated in metastatic HCC that was correlated to poor patient prognosis.

Importantly, we demonstrated that combined sorafenib or radiotherapy with NOX1 inhibition synergistically reduced the metastatic potential of HCC cells and enhanced the therapeutic efficacy. Bioinformatics analysis revealed that NOX1 contributed to HCC metastasis and therapy resistance by modulating ROS homeostasis, cellular antioxidant systems and inflammatory pathways.

In this study, we investigated the effects of hypoxia on MIC19 and its regulatory mechanisms in non-small cell lung cancer (NSCLC). We showed that the expression levels of MIC19 were significantly increased in NSCLC, which were associated with advanced stages and a poor prognosis in patients with NSCLC.

We revealed that USP3 mediated the hypoxia-induced upregulation of MIC19 expression in A549 and PC9 cells. In the hypoxic microenvironment, HIF-1α bound to the USP3 promoter region and promoted USP3 expression, which in turn stabilized MIC19 through K48-linked deubiquitination, thereby driving NSCLC progression.

In this study we investigated the relationship between neuronal activity and neuroinflammation in an ischemic mouse model using chemogenetic techniques. MCAO cerebral ischemia model was established in mice; in vitro oxygen-glucose deprivation/reoxygenation (OGD/R) was established in PC12 neurons. By measuring c-Fos expression, we showed that MCAO caused the activation of both excitatory and inhibitory neurons within the M1 primary motor cortex, which subsequently induced reactive activation of local microglia through the secretion of unique neuronal extracellular vesicles (EVs). Chemogenetic inhibition of abnormal neuronal activity in stroke-affected cortical neurons reversed microglia activation and reduced neuronal apoptosis. By analyzing the miRNAs in EVs from the ischemic M1 cortex, we found that miR-128-3p was significantly downregulated in ischemia-challenged neurons and their EVs, leading to neuronal injury and proinflammatory polarization of microglia. Intravenous injection of miR-128-3p mimics significantly improved neuronal survival, reduced neuroinflammation accompanied by better functional recovery after ischemic stroke. In summary, stroke-induced abnormal neuronal activity reduces miR-128-3p levels in ischemic neurons and EVs, leading to increased microglia activation and neuronal injury after a stroke.

In vitro, KLX inhibited the proliferation and migration of HepG2 and Hep3B cells in a dose-dependent manner.
