| 1 | Regulatory Effect of E2,IL-6 and IL-8 on the Growth of Epithelial Ovarian Cancer Cells显示文摘To determine the regulatory effects of estrogen and cytokine IL-6 and IL-8 on the growth of epithelial ovarian cancer (OVCA), we first examined the status of estrogen receptors (ERα and ERβ), IL-6 receptor (IL-6Rα and gp130), and IL-8 receptor (IL-8RA and IL-8RB) on five epithelial OVCA cell lines by semiquantitative RT-PCR and Western blot analysis. Results showed that the expressions of these receptors were variable on the five cells.Those OVCA cells expressing the receptors were selected to study related molecular mechanism. MTT assay was performed to observe the effects of 17β-estradiol (E2), IL-6 and IL-8 on cell proliferation. We discovered that E2 markedly promoted the proliferation of CAOV-3 and OVCAR-3 cell in a time- and dose-dependent manner.Tamoxifen (Txf), an ER inhibitor, completely blocked the proliferation of the E2-induced cells, and IL-6- or/and IL-8-neutralizing antibody only showed partially blocking activity. IL-6 and IL-8 were able to significantly stimulate CAOV-3 and OVCAR-3 cell proliferation in a time- and dose-dependent manner, which had a potential synergistic effect on CAOV-3 cells but not on OVCAR-3 cells. The cell proliferation induced by these two cytokines was abolished completely by their specific neutralizing antibodies, partially by Txf, but not by unrelated goat IgG.Taken together, our results suggested that estrogen, IL-6 and IL-8 could modulate OVCA growth by forming a reciprocal cascade with amplifying effect.

| 2 | Combined cell grafting and VPA administration facilitates neural repair through axonal regeneration and synaptogenesis in traumatic brain injury显示文摘Neuronal regeneration and functional recovery are severely compromised following traumatic brain injury(TBl).Treatment options,including cell transplantation and drug therapy,have been shown to benefit TBl,although the underlying mechanisms remain elusive.In this study,neural stem cells(NSCs)are transplanted into TBl-challenged mice,together with olfactory ensheathing cells(OECs)or followed by valproic acid(VPA)treatment.Both OEC grafting and VPA treatment facilitate the differentiation of NSCs into neurons(including endogenous and exogenous neurons)and significantly attenuate neurological functional defects in TBl mice.Combination of NSCs with OECs or VPA administration leads to overt improvement in axonal regeneration,synaptogenesis,and synaptic plasticity in the cerebral cortex in TBl-challenged mice,as shown by retrograde corticospinal tract tracing,electron microscopy,growth-associated protein 43(GAP43),and synaptophysin(SYN)analyses.However,these beneficial effects of VPA are reversed by local delivery of N-methyl-D-aspartate(NMDA)into tissues surrounding the injury epicenter in the cerebral cortex,accompanied by a pronounced drop in axons and synapses in the brain.Our findings reveal that increased axonal regeneration and synaptogenesis evoked by cell grafting and VPA fosters neural repair in a murine model of TBl.Moreover,VPA-induced neuroprotective roles are antagonized by exogenous NMDA administration and its concomitant decrease in the number of neurons of local brain,indicating that increased neurons induced by VPA treatment mediate axonal regeneration and synaptogenesis in mice after TBl operation.Collectively,this study provides new insights into NSC transplantation therapy for TBI. | Sujuan Liu Haili Tian Yanmei Niu Chunxia Yu Lingjian Xie Zhe Jin Wenyan Niu Jun Ren Li Fu Zhi Yao | 2022 | Acta Biochimica et Biophysica Sinica2022，54，9： | 1 |
