Background Tumor necrosis factor alpha (TNF-alpha), also known as cachetin, is a memberof the TNF superfamily of cytokines that is a potent lymphoid factor with effecs on a wide range of target cells. TNF exerts proinflamatory signals va binding and inducing trimerization of TNF-receptor 1 (TNF-R1) expressed on most normal and transformed cells. TNF signaling regulates hematopoiesis, differentiation, endothelial cell activation, apoptosis, lipid metabolism, tumor progression, and immune surveillance. Dysregulation of TNF or its receptors is implicated in numerous diseases including cancer, osteoporosis, autoimmune disease, diabetes, and atherosclerosis.

U2OS cells transfected with con‐shRNA (a), U2OS‐TNFR1‐KD + RelA‐KD (b), U2OS‐TNFR1‐KD + RelB‐KD (c), U2OS‐TNFR1‐KD + c‐RelA‐KD (d), U2OS‐SPD304 (e), U2OS‐TNFR1‐KD (f), U2OS‐RelA‐KD + CUL4B‐KD (g), U2OS‐CUL4B‐KD (h), U2OS‐TNFR1‐KD + CUL4B (i), U2OS‐SPD304 + CUL4B (j), U2OS‐TNFR1‐KD + RelA‐KD + CUL4B (k), U2OS‐TNFR1‐KD + RelB‐KD + CUL4B (l), and U2OS‐TNFR1‐KD + c‐Rel‐KD + CUL4B (m) were subjected to western blots to examine the protein levels of TNFR1, RelA, RelB, c‐Rel, and CUL4B. GAPDH was used as a loading control. (B) Blockage of the TNFa/NFkB axis inhibited osteosarcoma cell proliferation. Cells used in (A) were analyzed using the MTT assay to evaluate cell proliferation with absorbance measurement at 490 nm. (C) Blockage of the TNFa/NFkB axis decreased colony formation rates. Cells from A were seeded onto 12‐well plates and cultured with 0.1 mL of fresh medium containing 0.5% FBS for two weeks. **P < 0.001. (D) Blockage of the TNFa/NFkB axis decreased cell invasion. Cells from A were subjected to Boyden chamber assays, and the invasive cells were counted. **P < 0.001. (E) Blockage of the TNFa/NFkB axis decreased the in vivo tumor forming ability. Cells from A were injected intradermally into the flanks of mice. Tumor volumes were measured with fine calipers at 5‐day intervals.

(A) Representative microphotographs of tissue sections subjected to immunoperoxidase-based immunohistochemical staining for TNF-a (brown color), TNF-R1, and TNF-R2 (purple color) are shown. TNF-a, TNF-R1, and TNF-R2 immunostaining is strongly increased either in the hyperplastic lining or in the sublining layers of the HA synovium compared to non-inflamed OA control synovium. Original magnification: ×10 and ×20. Scale bar: 200 µm (×10 panels), 100 µm (×20 panels). (B) Western blotting of total protein extracts from the synovium of HA patients (n = 10) and OA controls (n = 8). Representative immunoblots for TNF-a, TNF-R1, and TNF-R2 are shown. The densitometric analysis of the bands normalized to a-tubulin is reported in the histograms. Data are the mean ± SEM of the optical density in arbitrary units (a.u.). * p < 0.05 vs. OA (Student’s t-test).

(A) Western blotting of total protein extracts from cultured HA-FLS and osteoarthritis control FLS (OA-FLS). Representative TNF-a, TNF-R1, and TNF-R2 immunoblots are shown; a-tubulin was used as a loading control. The densitometric analysis of the bands normalized to a-tubulin is reported in the histograms. Data are mean ± SEM of optical density in arbitrary units (a.u.). * p < 0.05 vs. OA-FLS (Student’s t-test). (B) Cell viability evaluated at the basal condition or after treatment with recombinant human TNF-a (10 ng/mL) using the water-soluble tetrazolium (WST)-1 cell proliferation reagent. Cell viability in response to TNF-a is expressed as the percentage increase/decrease over the basal response for both HA-FLS and OA-FLS. Bars represent the mean ± SEM. Results are representative of three independent experiments performed with each one of the six HA-FLS and six OA-FLS lines. * p < 0.05 vs. the respective basal condition (Student’s t-test). (C) Levels of active (cleaved) caspase-3 in HA-FLS and OA-FLS, as measured by the specific enzyme-linked immunosorbent assay on cell lysates. Data are the mean ± SEM of three independent experiments performed in triplicate with each one of the six HA-FLS and six OA-FLS lines.
Description Relative gene expression and localization of TLR4, IDO1 and AIF1 in the canine uterus. (A–C) Relative gene expression as determined by semi-quantitative real time (TaqMan) PCR (mean ± SEM). One-way ANOVA was applied to test the variation among the investigated groups, revealing: P = 0.0033 for TLR4, P = 0.03 for IDO1, and P = 0.04 for AIF1. In the case of P < 0.05, this was followed by Tukey-Kramer multiple comparisons post-test. Bars with asterisks differ at: *P < 0.05, **P < 0.01. (D–M) Immunohistochemical localization of members of the TNF-system, IDO1, and AIF1 in the canine uterus at selected stages of early pregnancy. Signals of TNFa were present in macrophages during the pre-implantation (D) and implantation (E) periods. Similarly, both TNFR1 (F) and TNFR2 (G,H) were present in macrophages. In addition, weaker signals for both receptors were also observed in epithelial cells of uterine glands during pre-implantation (F,G) and in endothelial cells (F,H). Positive signals of IDO1 were detected in macrophages between superficial glands during pre-implantation (I) and were also detected in endothelial cells at the time of implantation (J). At post implantation, weaker signals were observed in macrophages localized in deep endometrium layers, as well as in endothelial cells (K). AIF1 positive signals were identified in macrophages close to superficial uterine glands in pre-implantation (L) and implantation (M) stages, while at post-implantation they were localized in the deep layer of the endometrium (N). Some weak signals were also observed in uterine glands at the pre-implantation period (L), while apparently stronger signals were observed in the same glands at implantation (M) and post-implantation (N). Weak positive signals were also detected in endothelial cells (M, N) (solid arrow = macrophages; closed arrowhead = uterine gland; open arrowhead = blood vessel). No staining is observed in the isotype controls [inset in (D,F,G,I,L)].
