Aspirin may exhibit antitumor activities, as it is able to inhibit cell proliferation. However, the ability of aspirin to inhibit cellular proliferation in Hep-2 cells and its underlying molecular mechanisms have been poorly determined. The aim of the present study was to investigate whether aspirin may induce cell apoptosis in the neoplastic cell line Hep-2. The effects of aspirin on the migratory and invasive abilities of Hep-2 cells were also investigated using Transwell assays. In the present study, it was demonstrated that aspirin induced apoptosis and inhibited proliferation, migration and invasion in Hep-2 cells. Aspirin also significantly decreased the expression of B-cell lymphoma 2 (Bcl-2) and caspase-3, and increased the expression of Bcl-2-associated X protein, suggesting that aspirin induced apoptosis through the intrinsic apoptotic pathway. Hep-2 cells treated with aspirin exhibited a significant upregulation of phosphatase and tensin homolog (PTEN) and decreased levels of phosphorylated protein kinase B (AKT). However, the total amount of AKT protein was not altered in response to aspirin treatment. Furthermore, the expression of nuclear factor (NF)-κB and survivin, which are the downstream targets of the PTEN/AKT signaling pathway, was inhibited. These results indicated that the molecular mechanism underlying the antitumor effects of aspirin may be associated with the inhibition of tumor invasion and induction of apoptosis by regulating the activity of the PTEN/AKT/NF-κB/survivin signaling pathway.

Novel thiazole analogs 3a, 3b, 4, 5, 6a-g, 8a, 8b, 9a-c, 10a-d and 11 were designed and synthesized as molecular mimetics of sunitinib. antitumor activity of the obtained compounds was investigated against HepG2, HCT-116, MCF-7, HeP-2 and HeLa cancer cell lines. The obtained data showed that compounds 3b and 10c are the most potent members toward HepG2, HCT-116, MCF-7 and HeLa cells.

Laryngeal squamous cell carcinoma is a common type of head and neck cancer. This study investigated the role of the TRPM2 channel in doxorubicin (DOX)-induced cell damage in human laryngeal squamous cancer cells (Hep-2). Cells were exposed to various DOX concentrations and the appropriate dose was found.

Background: Lidocaine is a traditional local anesthetic, which has been reported to trigger apoptosis through the mitochondrial pathway, independent of death receptor signaling. Cuproptosis is a copper triggered mitochondrial cell death mode. In this study, we explored the biological effects of lidocaine on cuproptosis in Hep-2 cells and studied the relevant mechanisms.

Human metapneumovirus (HMPV) is an important causative agent of respiratory tract disease. Fundamental knowledge of the interaction between HMPV and the innate immune system could lead to the design of novel antiviral therapies. Previously, we demonstrated that HMPV M2-2 deletion mutants had hypermutated genomes and contained defective interfering particles (DIs), which are potent inducers of the IFN response.
