    SMP alleviated cell damage by inhibiting NIK/NF-κB. After the appropriate SMP concentration (0, 0.01, 0.1, 1, 10, 20, 40, 80, or 160 μg/mL) was determined in normal Hepa1-6 cells, the effect of SMP on the expression of inflammation-induced marker genes was evaluated in Hepa1-6 cells overexpressing the NIK gene. Hepa1-6 cells were divided into the following five groups (n = 3): the oe-vector group (overexpressing vector and administered saline), the solvent group (overexpressing the NIK gene and administered solvent), and the SMP group (overexpressing the NIK gene and administered SMP at concentrations of 10, 20, or 40 μg/mL). (A) CCK8 assay was used to measure the viability of normal Hepa1-6 cells; (B) Protein expression levels of NRF2, NIK, and p52 determined via Western blot; (C) Relative dual luciferase activity indicating transcription activity; (D) mRNA expression levels of TNF-α, CCL2, and CCL5, as detected by qPCR; (E) Cytokine levels, including those of TNF-α, CCL2, and CCL5, were detected via ELISA; (F) The mRNA expression levels of CXCL5 and NOS2 were detected by qPCR. Data are presented as the mean ± SD from three independent experiments (n = 3), with three technical replicates per independent experiment. Statistical significance was determined by one-way ANOVA followed by the Student–Newman–Keuls post hoc test. N = 3, *P < 0.05, **P < 0.01, ***P < 0.001. SMP, Silybum marianum peptides.

Serine/threonine kinase mitogen-activated protein 4 kinase 4 (Map4k4) is linked with oxidative injury and possibly associated with premature ovarian failure and ovarian dysgenesis.. Herein, we investigated the function and mechanism of Map4k4 in a PCOS rat model. A microarray from GEO database identified Map4k4 was up-regulated in the ovarian of PCOS rats, and functional enrichments suggested that oxidative stress-associated changes are involved.
