OBJECTIVE: To investigate the efficacy of Gouqizi () seed oil (FLSO) on D-gal induced inflammation in testis of rats and .
METHODS: In aging Sertoli cells (TM4 cells) induced by D-galactose (D-gal), the expression of upregulated aging-related proteins. The number of cells counted by cell counting kit (CCK)-8 assay showed a high number of cells disposed with FLSO at 50, 100 and 150 μg/mL compared to that for the aging model. , male Sprague-Dawley rats ( = 50, 8-week-old, 230-255 g) were randomly categorized into control, aging model, and FLSO (low-, medium-, and high-dose) groups. The expression of nuclear factor-κB (NF-κB) and its upstream factors [Janus kinase 1 (JAK1) and signal transducerand activator of transcription 1 (STAT1)] was detected by Western blot and immunofluorescence, related inflammatory factors quantified by enzyme-linked immunosorbent assay. Evaluation of testicular tissue by Johnsen score, the spermatogenic function was explored.
RESULTS: The expression of interleukin-1β (IL-1β) ( < 0.05), IL-6 ( < 0.001), and tumor necrosis factor α (TNF-α) ( < 0.05) was decreased significantly, while that of heme oxygenase-1 (HO-1) ( < 0.001) and IL-10 ( < 0.05) was increased in cells disposed with FLSO 100 μg/mL. FLSO inhibited the expression of NF-B and declined p-p65/p65 ( < 0.01), as detected by Western blotting. In, the levels in serum of IL-1β ( < 0.001), IL-6 ( < 0.05), and TNF-( < 0.01) declined while IL-10 ( < 0.05) was upregulated post-FLSO treatment. In addition, the expression of JAK-1 and STAT1 increased significantly in testicular tissue of rats treated with FLSO as compared to the aging model of rats ( < 0.001), while the expression of NF-κB ( < 0.001) declined in the testis in the FLSO group, as assessed by immunofluorescence. The levels of inhibor B and testosterone in serum both increased (< 0.05).
CONCLUSIONS: In conclusion, this study determined the protective effects of FLSO to tolerate inflammatory injury in the testis, indicating that FLSO alleviates inflammation JAK-1/STAT1/NF-κB pathway.
