ABSTRACT: Single crystals of octaiodine henacosarsenic pentacosagermanium were grown by chemical transport reactions. The structure is isotypic with the analogous clathrates-I. In this structure, the statistically occupied clathrand atoms (As,Ge)(46) form bonds in a distorted tetra-hedral coordination and their arrangement can define two polyhedra of different sizes; one is an (As,Ge)(20) penta-gonal dodeca-hedron, and the other is an (As,Ge)(24) tetra-kaideca-hedron. The guest atom (iodine) resides inside these polyhedra with site symmetry m3 (Wyckoff position 2a) and 2m (Wyckoff position 6d), respectively.

Project description:Background: Acute lung injury (ALI) is a life-threatening disease without effective chemotherapy at present. Liang-Ge-San (LGS) is a famous traditional Chinese medicine formula, which is used to treat ALI in China. However, only a few studies have addressed the mechanisms of LGS in ALI. Purpose: To evaluate the anti-inflammatory effects of LGS on lipopolysaccharide (LPS)-induced ALI, and to explore its underlying molecular mechanism. Methods: Murine RAW264.7 cells were treated with LGS and LPS (1 μg/ml). The generation of IL-6, TNF-α, IL-1β was detected by ELISA. The protein expressions of STAT3 and P-STAT3 (Tyr705) were determined by Western blotting and fluorescence confocal microscopy. STAT3 transcriptional activity was investigated by luciferase reporter gene assay. qPCR was used to detect the expressions of microRNA-21 (miR-21), STAT3, and IL-6. DSS cross-linking assay was used to assess the change of STAT3 dimer. In vivo anti-inflammatory effects of LGS were evaluated in an ALI mouse model induced by tracheal instillation of LPS (3 mg/kg). The anti-ALI effects were evaluated by ELISA, qPCR, Western blotting, BCA, and H&E assays. Results: LGS suppressed LPS-stimulated IL-6, TNF-α, and IL-1β generation in murine macrophages RAW264.7. Moreover, LGS down-regulated protein levels of P-STAT3 (Tyr705) and STAT3, inhibited STAT3 transcriptional activity, and up-regulated miR-21. Furthermore, blockage of miR-21 antagonized the inhibitory effects of LGS on the production of IL-6 and the expressions of P-STAT3 (Tyr705) and STAT3 as well as the formation of STAT3 dimer. Critically, LGS up-regulated the expression of miR-21 and inhibited the protein expressions of STAT3 and P-STAT3 (Tyr705) to reduce the release of IL-6 and inflammatory cell infiltration as well as the degree of edema in LPS-induced ALI mice. Conclusion: LGS inhibited LPS-induced ALI through up-regulating miR-21 and subsequently inhibiting the STAT3 signaling pathway, thereby decreasing the release of IL-6.

Project description:BackgroundEpithelial ovarian cancer (EOC) is the most common cause of gynecological malignancy-related mortality. Ovarian clear cell carcinoma (CCC) has unique clinical characteristics and behaviors that differ from other histological types of EOC, including a frequent association with endometriosis and a highly chemoresistant nature, resulting in poor prognosis. However, factors underlying its malignant behavior are still poorly understood. Aberrant expression of microRNAs has been shown to be involved in oncogenesis, and microRNA-21 (miR-21) is frequently overexpressed in many types of cancers. The aim of this study was to investigate the role of miR-21 in 17q23-25 amplification associated with CCC oncogenesis.MethodsWe identified 17q23-25 copy number aberrations among 28 primary CCC tumors by using a comparative genomic hybridization method. Next, we measured expression levels of the candidate target genes, miR-21 and PPM1D, for 17q23-25 amplification by real-time RT-PCR analysis and compared those data with copy number status and clinicopathological features. In addition, immunohistochemical analysis of PTEN (a potential target of miR-21) was performed using the same primary CCC cases. We investigated the biological significance of miR-21 overexpression in CCC using a loss-of-function antisense approach.Results17q23-25 amplification with both miR-21 overexpression and PTEN protein loss was detected in 4/28 CCC cases (14.2%). The patients with 17q23-25 amplification had significantly shorter progression-free and overall survival than those without 17q23-25 amplification (log-rank test: p = 0.0496; p = 0.0469, respectively). A significant correlation was observed between miR-21 overexpression and endometriosis. Both PTEN mRNA and PTEN protein expression were increased by miR-21 knockdown in CCC cells. We also confirmed that miR-21 directly bound to the 3'-untranslated region of PTEN mRNA using a dual-luciferase reporter assay.ConclusionsMiR-21 is a possible driver gene other than PPM1D for 17q23-25 amplification in CCC. Aberrant expression of miR-21 by chromosomal amplification might play an important role in CCC carcinogenesis through the regulation of the PTEN tumor suppressor gene.

Project description:Background: LINE-1 elements make up the most abundant retrotransposon family in the human genome. Full-length LINE-1 elements encode their own reverse transcriptase (RT). They are expressed at low levels in normal cells and abundantly in cancer cells. RT down-regulation, by either RNA interference to LINE-1 elements, or by RT inhibitory drugs, was previously found to reduce proliferation and promote differentiation in cancer cells and to antagonize tumor growth in animal models. Results: We report that the RT inhibitor efavirenz effectively inhibit proliferation of a variety of human tumorigenic cell lines while only slightly affecting the proliferation of human normal fibroblast cell line, a difference that nicely matches RT expression in the former cell lines and its lack in the latter. The finding of Alu and LINE-1 containing DNA:RNA hybrid molecules - identified by CsCl density gradients - selectively in cancer but not in normal cells, suggests that RNA transcripts from these retroelements are candidate substrates for reverse transcription. These hybrids disappear in tumor cells treated with efavirenz, under the same conditions which induce an extensive reprogrammed expression profiles for protein-coding genes, microRNAs (miRNAs) and ultraconserved regions (UCRs). The RT-sensitive miRNAs and UCRs are significantly associated with Alus sequences. Conclusions: A novel RT-dependent mechanism governs the balance between single-stranded and double-stranded RNA production. In cancer cells, the abundant LINE-1-encoded RT reverse-transcribes retroelement-derived mRNAs, generating RNA:DNA hybrids. We propose that this impairs the formation of double-stranded RNAs and the ensuing production of small regulatory RNAs, with a direct impact on gene expression. RT inhibition restores the M-^QnormalM-^R small RNA profile and the regulatory networks that depend on them. Thus, the retrotransposon-encoded RT drives an epigenetic mechanism crucial to maintenance of the transformed state in tumor cells.
