Enrichment analysis revealed that differentially expressed genes of human OM-MSCs mainly participated in cell cycle regulation, secretin of cytokines and so on. Meanwhile, hypoxic condition significantly promoted proliferation and inhibited apoptosis of human OM-MSCs, following loss-of-function assays confirmed that lncRNA DARS-AS1 were involved in this regulatory process by hypoxic condition. Further prediction of targeted genes and the construction of lncRNA-miRNA-mRNA interaction network enriched the significance regarding the mechanism of DARS-AS1. Altogether, these findings provided a new perspective for understanding the molecules expression patterns in hypoxia that contributed to corresponding phenotype alterations of OM-MSCs.

GnRH-DFF40 (gonadotropin releasing hormone-DNA fragmentation factor 40) humanized recombinant immunotoxin serves as a prospective candidate for targeted therapy of malignancies with over-expressed gonadotropin releasing hormone receptor (GnRHR). In this study, we attempted to generate a GnRH-based chimeric protein composed of human DFF40 fused with GnRH which encodes an apoptotic nuclease and specifically targets cancer cells displaying GnRH receptor overexpression. A codon optimized, synthetic GnRH-DFF40 fusion gene and its single counterpart (DFF40) were constructed in pET28a expression vector. Cytotoxicity of these expressed proteins were evaluated on three breast cancer cell lines (MCF7, MDA-MB231, and SKBR3). The stability and biological activity of the recombinant proteins were investigated in the treated cell line and cell-free system. Also, the ability of this fusion and its single form in inducing apoptosis, and inhibiting metastasis and migration were evaluated by flow cytometry, migration assay and wound healing analysis, respectively. In silico analyses were also done to understand the specific interactions between GnRH and its receptor. GnRH-DFF40 fusion protein and DFF40 were successfully expressed. The purified chimeric protein showed dose-dependent cytotoxicity against all three cell lines. The recombinant fusion protein was biologically active with nucleolytic functionality and apoptosis induction ability. Moreover, the fusion could inhibit the invasion property of MDA-MB-231 cells. In silico analysis also showed that four residues from GnRH domain and 11 GnRHR residues had the most interaction sites for specific targeted delivery of the immunotoxin in cancer cells. Fusion construct could be a prospective candidate for targeted therapy of cancers upregulating GnRH receptor.

Antiretroviral therapy (ART) controls viral replication but cannot eradicate an infected virus and restore the immune response of patients. The gene expression profiles of whole blood, PBMCs, CD4+ and CD8+ T cells were obtained from GSE108297. Coexpression analysis was carried out to evaluate differentially expressed genes (DEGs) between strong and weak responder HIV controllers (HICs). Enrichment analysis was used to explore the biological functions of DEGs. https://www.selleckchem.com/products/VX-765.html The key genes with common DEGs were screened using the Lasso Cox model. Then, the immune scores of HICs and HAART were calculated by ssGSEA. The content of CD4+ and CD8+ T cells, key genes were verified by flow cytometry, RT-PCR and Western blot analysis. DEGs were clustered into 24 coexpression modules. DEGs related to general immune responses had the highest correlation with strong responding HICs, while DEGs mainly related to the apoptotic process had the highest correlation with weak responder HICs. The hub genes CD8A and CCT2, as well as the key genes TMEM132C and S100A9, were DEGs in HICs and HARRT. The immune score and flow cytometry showed that CD4+ and CD8+ T cells of HICs were lower than those of HARRT in whole blood. Experiments confirmed the expression of key genes in HICs and HARRT. The key genes identified in this study highlight the strong responder HICs features that to help the immune system control HIV-1 infection. These results will be useful for developing therapeutic targets.

In recent years, progress has been made in the study of β2-ARs. Here, we introduce the basic concepts of β2-ARs, related pathways, as well as application of blockers/agonists of β2-ARs, and β2-AR autoantibodies in COPD. Drugs targeting the β2-AR are being developed rapidly, and we expect them to improve the symptoms and prognosis of COPD patients in the future.After spinal cord injury (SCI), intestinal dysfunction has a serious impact on physical and mental health, quality of life, and social participation. Recent data from rodent and human studies indicated that SCI causes gut dysbiosis. Remodeling gut microbiota could be beneficial for the recovery of intestinal function and motor function after SCI. However, few studies have explored SCI with focus on the gut microbiota and "microbiota-gut-brain" axis. In this review, the complications following SCI, including intestinal dysfunction, anxiety and depression, metabolic disorders, and neuropathic pain, are directly or indirectly related to gut dysbiosis, which may be mediated by "gut-brain" interactions. Furthermore, we discuss the research strategies that can be beneficial in this regard, including germ-free animals, fecal microbiota transplantation, probiotics, phages, and brain imaging techniques. The current microbial research has shifted from descriptive to mechanismal perspective, and future research using new technologies may further demonstrate the pathophysiological mechanism of association of SCI with gut microbiota, elucidate the mode of interaction of gut microbiota and hosts, and help develop personalized microbiota-targeted therapies and drugs based on microbiota or corresponding metabolites.
