    Oncology Research, Vol.32, No.5, pp. 943-953, 2024, DOI:10.32604/or.2023.044775 - 23 April 2024

    Abstract Breast and lung cancers are the leading causes of mortality and most frequently diagnosed cancers in women and men, respectively, worldwide. Although the antitumor activity of chalcones has been extensively studied, the molecular mechanisms of isoliquiritigenin analog 2', 4', 4-trihydroxychalcone (metochalcone; TEC) against carcinomas remain less well understood. In this study, we found that TEC inhibited cell proliferation of breast cancer BT549 cells and lung cancer A549 cells in a concentration-dependent manner. TEC induced cell cycle arrest in the S-phase, cell migration inhibition in vitro, and reduced tumor growth in vivo. Moreover, transcriptomic analysis revealed that TEC More > Graphic Abstract

    Qiao Zhou1,2,3,, Nanxue Cui1,2,3,, Shihai Zhang1,2,3,#, Miaomiao Zhou4,#, Younian Xu1,2,3,#

    European Cytokine Network, Vol.34, No.3, pp. 21-27, 2023, DOI:10.1684/ecn.2023.0487

    Abstract Thymic stromal lymphopoietin (TSLP) is highly expressed in the central nervous system in response to inflammation, but its exact function remains unclear. In this study, we used a model of LPS-stimulated microglia to investigate the direct impact of TSLP on microglial activation and the underlying mechanism. We measured oxidative stress, expression of microglial activation markers, and inflammatory indexes. The results show that TSLP treatment increased the expression of TSLP receptors and reduced LPS-induced oxidative stress, inflammation, and the expression of M1-type markers in microglia. Interestingly, TSLP treatment also influenced the differentiation of microglia towards the More >
