[PMID: 37493703 PMCID: PMC10382077 DOI: 10.1590/1678-7757-2023-0162] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2023] [Accepted: 06/16/2023] [Indexed: 07/27/2023] Open
Abstract
BACKGROUND The roles and molecular mechanisms of tumor necrosis factor-α-induced protein 8-like 2 (TIPE2) in periodontitis remain largely unknown. OBJECTIVE This study aimed to determine the expression of TIPE2 and NF-κB p65 in rat Porphyromonas gingivalis-induced periodontics in vivo. METHODOLOGY Periodontal inflammation and alveolar bone resorption were analyzed using western blotting, micro-computed tomography, TRAP staining, immunohistochemistry, and immunofluorescence. THP-1 monocytes were stimulated using 1 μg/ml Pg. lipopolysaccharide (Pg.LPS) to determine the expression of TIPE2 in vitro. TIPE2 mRNA was suppressed by siRNA transfection, and the transfection efficiency was proven using western blotting and real-time PCR. The NF-κB pathway was activated by treating the cells with 1 μg/ml Pg.LPS to explore related mechanisms. RESULTS The expression of both TIPE2 and NF-κB p65 was increased in the gingival tissues of rat periodontitis compared with normal tissues. Positive expression of TIPE2 was distributed in inflammatory infiltrating cells and osteoclasts in the marginal lacunae of the alveolar bone. However, strong positive expression of TIPE2 in THP-1 was downregulated after Pg.LPS stimulation. TIPE2 levels negatively correlated with TNF-α and IL-1β. Decreased TIPE2 in THP-1 further promoted NF-κB p65 phosphorylation. Mechanistically, TIPE2 knockdown upregulated NF-κB signaling pathway activity. CONCLUSIONS Taken together, these findings demonstrate that TIPE2 knockdown aggravates periodontal inflammatory infiltration via NF-κB pathway. Interventions aimed at increasing TIPE2 may help in the therapeutic applications for periodontitis.

Aqueous Extract of Salvia miltiorrhiza Bunge- Radix Puerariae Herb Pair Attenuates Osteoporosis in Ovariectomized Rats Through Suppressing Osteoclast Differentiation. Front Pharmacol 2021; 11:581049. [PMID: 33708107 PMCID: PMC7941748 DOI: 10.3389/fphar.2020.581049] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2020] [Accepted: 12/11/2020] [Indexed: 11/21/2022] Open
Abstract
Traditional herb pair Salvia miltiorrhiza Bunge-Radix Puerariae (DG) owns various biological activities including anti-inflammatory and anti-oxidative stress. Oxidative stress is one high-risk factor for osteoporosis, then effect of DG on osteoporosis and underlying mechanisms was explored both in vivo and in vitro. Firstly, the predication from network pharmacology hinted that DG has the potential for ameliorating osteoporosis. Consistent with predication, DG significantly restored bone loss and deficiency of type II collagen, decreased TRAP and Cathepsin K positive areas in femur. Meanwhile it improved important characteristics of microarchitectural deterioration of tissue, reduced the numbers of NFATc1-positive osteoclast in the vertebra as well as decreased the serum osteoclast-specific cytokine RANKL and OPG release in OVX rats exhibiting its protective effect against osteoporosis. In vitro, DG noticeably decreased osteoclastic-special marker protein expressions of RANK, c-Fos and NFATc1. Furthermore, autophagy pathway p62/LC3B, ROS production and NF-κB were all activated by RANKL stimulation and blocked by DG pretreatment. Moreover, autophagy inhibitors, ROS scavenger, Ca2+ chelator and NF-κB inhibitor remarkably suppressed c-Fos and NFATc1 expressions. Taken together, DG may ameliorate osteoporosis by regulating osteoclast differentiation mediated by autophagy and oxidative stress. This study provided a mechanistic basis for DG treating osteoporosis and offered a safe dose for DG in preventing and improving bone diseases.

Abstract
Tumor necrosis factor-α-induced protein 8-like 1 (TIPE1) functions as a tumor suppressor in several types of cancer, including lung and breast cancer. The present study aimed to determine the level of expression and the function of TIPE1 in ovarian cancer. TIPE1 expression was determined in tissue microarrays and ovarian cancer cells, and these data were analyzed to assess the association between TIPE1 expression and prognosis in patients with ovarian cancer. The potential antitumor effects of TIPE1 were investigated in vitro and in a xenograft mouse model. Furthermore, the underlying molecular mechanism by which TIPE1 regulates ovarian cancer growth was determined via flow cytometric analysis, western blotting and rescue experiments. The results of the present study indicated that TIPE1 levels were markedly decreased in ovarian cancer tissues, and its level of expression was associated with a favorable prognosis of patients with ovarian cancer. In addition, ectopic TIPE1 expression significantly impaired A2780 and SKOV3 cell proliferation and colony formation in vitro, which was accompanied by efficient inhibition of xenograft tumor growth in mice. Investigations into the underlying molecular mechanism demonstrated that TIPE1 induced ovarian cancer cell apoptosis by promoting caspase protein expression. Inhibition of caspase-dependent apoptosis by z-VAD blocked TIPE1-mediated inhibition of the proliferation and induction of apoptosis in ovarian cancer cells. Collectively, the results of the present study suggest that TIPE1 may be a potential prognostic predictor and therapeutic target for patients with ovarian cancer.

Front Oncol 2019; 9:400.

Abstract
TIPE1, which acts as a cell death regulator, has emerged as a tumor suppressor in the process of carcinogenesis. However, our recent research demonstrated that it serves as an oncogene in the pathogenesis of cervical cancer, indicating that the role of TIPE1 in carcinogenesis needs to be further evaluated. In this study, we show that TIPE1 is able to inhibit breast cancer cell growth both in vivo and in vitro. Functionally, TIPE1 inhibits cancer cell proliferation preferentially by downregulating ERK phosphorylation. Furthermore, the expression of TIPE1 is decreased in breast cancer tissues compared to matched adjacent tissues, and its expression is positively correlated with patients' lifespan. These data indicate that TIPE1 suppresses breast cancer proliferation by inhibiting the ERK signaling pathway. This study also suggests that TIPE1 could serve as a potential therapeutic target and a diagnostic biomarker for breast cancer.
