Abstract
Paeoniflorin (PF) has been demonstrated to have an anti-allergic and anti-inflammatory effect in the treatment of allergic contact dermatitis (ACD). However, its clinical application is hampered by the lacking of comprehensive mechanical explanation. This research aimed to study the effect of PF on the proliferation, apoptosis and cytokines secretion as well as the expression of nuclear factor-kappa B (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways of T lymphocytes activation in vitro and in vivo. We found that PF depressed human T lymphocytes activation via inhibition ofinterferon-gamma (IFN-γ) production and NF-κB/IκBα and p38 MAPK signaling pathway in vitro, also PF could attenuate such ACD responses by inhibiting the production of IFN-γ and NF-κB/IκBα pathway in T lymphocytes of ACD mouse model, suggesting that PF might be useful for the treatment of T cell-mediated allergic inflammatory disorders such as ACD. This would make PF a promising T cell-targeted drug candidate for further study because of its immunosuppressive and anti-inflammatory effects.

SPECTROCHIMICA ACTA. PART A, MOLECULAR AND BIOMOLECULAR SPECTROSCOPY 2020; 228:117718. [PMID: 31818647 DOI: 10.1016/j.saa.2019.117718] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/02/2019] [Revised: 10/09/2019] [Accepted: 10/26/2019] [Indexed: 06/10/2023]
Abstract
Mitoxantrone (MTX), one representative of anthraquinone ring anticancer drugs, reveals excellent anticancer effects in acute leukemia. Though current studies have shown that MTX-induced acute leukemia cell apoptosis is implemented by inserting into DNA, and then leading to DNA breakage and the subsequent transcription termination, but the specific location information of MTX embedded in DNA remains unknown. In this study, combining surface enhanced Raman scattering (SERS) and principal component analysis (PCA), we achieve the biochemical changes of MTX-induced Jurkat cell apoptosis and the location information of MTX embedded in DNA. In contrast, we also present the corresponding result of Daunorubicin (DNR)-induced Jurkat cell apoptosis. It is found that the location of MTX embedded in DNA of Jurkat cell is different from DNR, in which the action site of MTX is mainly implemented by blocking and destroying AT base pairs while DNR is performed by embedding and destroying GC base pairs and then the base A. Clearly, this achieved information is very useful for the designing and modification of anthraquinone ring anticancer drugs.
