    Akkermansia muciniphila Enhances the Antitumor Effect of Cisplatin in Lewis Lung Cancer Mice by Zhuo Chen, Xiang Qian, Shasha Chen, Xiaoxuan Fu, Guanjun Ma, Aiqin Zhang

    Published 2020-01-01
    “…In addition, transcriptome analysis indicated that Akk combining with CDDP increased obviously the levels of IFI27l2 and IGFBP7 and was related to those pathways including the cytokine-cytokine receptor interaction, Th17 cell differentiation, FOXO, JAK-STAT, and PI3K-Akt signaling pathways. These results suggested that the therapeutic efficacy of the combined treatment of Akk and CDDP was superior to the only CDDP treatment, which could enhance immune regulation and would be a promising strategy for the treatment of lung cancer.…”
