Mouse Colonic Organ Culture:

Mouse fetal colonic tissues were obtained at E 18.5 with or without HC treatment during pregnancy, and 10-wk-old adult mice colonic tissues were cut into 3-mm pieces and cultured under conditions described in the human colonic organ culture section. After 2h at 37 C, tissues were stimulated with ultra purified LPS 0111:B4 from Escherichia coli (List Biological Laboratories, Campbell, CA) or PBS for 45min and 6h. Supernatants were collected and stored at 20 C for enzyme-linked immunosorbent assay (ELISA) analysis.

GBS Coculture with Extraplacental Choriodecidual Membranes:

GBS in early exponential growth phase was diluted with DMEM/1% FBS to an estimated 110⁶ colony forming units/mL (CFU/mL). Inoculant concentrations were validated by overnight growth on 5% sheep blood agar with erythromycin. GBS was heat killed by incubating bacterial culture at 70 C for 15 min. Lack of viability was confirmed by plating GBS on 5% sheep blood agar. LTA and LPS treatments were made in DMEM/1% FBS. Following a 24-h acclimation, the medium of the choriodecidual punches was replaced with 1 mL GBS inoculant (~110⁶ CFU/mL), LTA (1 g/mL), LPS (100 ng/mL), or fresh DMEM/1%FBS (control). Following 24 h of incubation with GBS, medium from the choriodecidual punches was filtered through a 0.2 m pore filter to remove the bacteria, and then stored at 80 C: this medium is referred to as GBS conditioned choriodecidual medium in this study. Medium from choriodecidual punches treated with LTA or LPS for 24 h was also 0.2 m filtered and then stored at 80 C: this medium is referred to as LTA or LPS conditioned choriodecidual medium. Coculture experiments were conducted in triplicate using extraplacental membranes from a minimum of seven women.

Gambogic acid suppresses the expression of cytokines at both mRNA and protein levels in LPS-stimulated bone marrow-derived primary macrophages:

We investigated the effects of gambogic acid on TLR4 ligand-induced cytokine expression in bone marrow-derived primary macrophages (BMDMs). When BMDMs were stimulated with LPS, a TLR4 ligand, gambogic acid reduced the protein levels of pro-inflammatory cytokines such as TNF, IL-1, IL-12, and IL-6 (Fig. 2), as well as the mRNA levels (Fig. 3), both of which are normally increased by LPS, demonstrating that the inhibitory effects of gambogic acid were achieved at the transcriptional level. …
