SRY (sex-determining region Y)-box 13 (Sox13), a member of group D of the SRY-related high mobility group (HMG) box (Sox) family, is a critical regulator of embryonic development and cartilage formation. Few studies have investigated the role of Sox13 in tumorigenesis. The present study reveals the clinical significance and biological function of Sox13 in hepatocellular carcinoma (HCC). First, the expression of Sox13 in HCC samples was evaluated by qRT-PCR and western blotting, and its association with clinicopathological features and prognosis was determined. We found that Sox13 expression was higher in tumor tissue than in paired nontumor tissue. The upregulation of Sox13 was associated with poor differentiation, metastasis, recurrence and poor overall, and tumor-free survival of HCC patients. The function of Sox13 on HCC cell migration and invasion was then assessed by Transwell assay, and the results demonstrated that Sox13 promoted HCC cell invasion, migration, and epithelial-to-mesenchymal transition (EMT). Notably, the invasion, migration, and EMT of HCC cells induced by Sox13 overexpression could be abolished by Twist1 depletion, and Sox13 was positively correlated with Twist1 at both the mRNA and protein levels. Mechanistically, we revealed that Sox13 activated Twist1 transcription and consequently upregulated Twist1 expression. Furthermore, Sox13 formed a heterodimer with Sox5, and this heterodimer functionally cooperated to enhance the transcriptional activity of Twist1. Our findings suggest that Sox13 serves as an oncogene in HCC, and might be a novel prognostic and therapeutic candidate.MicroRNAs regulate gene expression at the posttranscriptional level, and this process has been shown to be implicated in the pathological processes of temporal lobe epilepsy. At present, studies about the impact of microRNA-181a (miR-181a) on epilepsy have focused on hippocampal neurons, and the effect of miR-181a on other cells in the hippocampus remains poorly understood. Herein, we explored the role of miR-181a-5p in a lithium-pilocarpine model of epilepticus in immature rats. We found that the hippocampal expression level of miR-181a-5p was increased. Inhibition of miR-181a-5p protected the hippocampus against epilepsy, including hippocampal insults, neuronal apoptosis, astrocyte and microglia activation, neuroinflammation, oxidative stress, mitochondrial function, and cognitive dysfunction. Moreover, miR-181a-5p inhibition exerted a seizure-suppressing effect via SIRT1 upregulation. Overall, our findings reveal the potential role of the miR-181a-5p/SIRT1 pathway in the development of temporal lobe epilepsy, and this pathway may represent a novel target for ameliorating epilepsy and its sequelae.With the understanding of the complex interaction between the tumour microenvironment and immunotherapy, there is increasing interest in the role of immune regulators in the treatment of head and neck squamous cell carcinoma (HNSCC). Activation of T cells and immune checkpoint molecules is important for the immune response to cancers. Immune checkpoint molecules include cytotoxic T lymphocyte antigen 4 (CTLA-4), programmed death 1 (PD-1), T-cell immunoglobulin mucin protein 3 (TIM-3), lymphocyte activation gene 3 (LAG-3), T cell immunoglobin and immunoreceptor tyrosine-based inhibitory motif (TIGIT), glucocorticoid-induced tumour necrosis factor receptor (GITR) and V-domain Ig suppressor of T cell activation (VISTA). Many clinical trials using checkpoint inhibitors, as both monotherapies and combination therapies, have been initiated targeting these immune checkpoint molecules. This review summarizes the functional mechanism and use of various immune checkpoint molecules in HNSCC, including monotherapies and combination therapies, and provides better treatment options for patients with HNSCC.The effects of donor-derived natural killer (NK) cell alloreactivity on disease relapse and transplant-related mortality following allogeneic stem cell transplantation have been described while the impact of recipient-derived NK cell alloreactivity on donor engraftment is not well known. Epitopes of HLA Class I molecules act as ligands for NK cell killer immunoglobulin-like receptors (KIR) regulating their cytotoxicity. As such, NK cell alloreactivity is predictable from KIR ligand mismatches between donors and recipients. We analyzed the impact of KIR ligand mismatch (KIR-L-MM) on donor engraftment in 70 cord blood transplants (CBT) and 26 haploidentical transplants (HaploSCT). In CBT, host-versus-graft-directed KIR-L-MM predicted primary graft failure; an effect not mitigated by use of ATG. This trend was most significant with HLA-C KIR-L-MM. In addition, graft-versus-host-directed KIR-L-MM predicted the dominant cord blood unit in double CBT. In the limited HaploSCT cohort, host-versus-graft-directed KIR-L-MM did not predict graft failure. Time to neutrophil engraftment was unaffected by KIR-L-MM in either CBT or HaploSCT.  https://www.selleckchem.com/  The direction of KIR-L mismatch may be a parameter to consider when selecting CBT units to ensure successful engraftment. The role of KIR-L-MM in CBT and HaploSCT engraftment merits further exploration in a large transplant database.The plasticity of cancer cell invasion represents substantial hindrance for effective anti-metastatic therapy. To better understand the cancer cells' plasticity, we performed complex transcriptomic and proteomic profiling of HT1080 fibrosarcoma cells undergoing mesenchymal-amoeboid transition (MAT). As amoeboid migratory phenotype can fully manifest only in 3D conditions, all experiments were performed with 3D collagen-based cultures. Two previously described approaches to induce MAT were used doxycycline-inducible constitutively active RhoA expression and dasatinib treatment. RNA sequencing was performed with ribo-depleted total RNA. Protein samples were analysed with tandem mass tag (TMT)-based mass spectrometry. The data provide unprecedented insight into transcriptome and proteome changes accompanying MAT in true 3D conditions.In the USA, California's highly-regarded Tobacco Control Program (CTCP) has defined its goal as "ending the tobacco epidemic for all population groups" by 2035. To understand local advocates' perceptions of endgame-oriented policies, we interviewed 28 advocates from California communities that had recently adopted tobacco control policies. There was no consensus among participants on which specific policies would constitute the tobacco endgame in California. There was an agreement, however, that policymakers should promote policies that would impact communities with the highest tobacco use prevalence and that policies should be 'clean', avoiding exemptions. Participants were cognizant of California's history of tobacco control policy innovations beginning locally and eventually being adopted at the state level. Many commented that recent policy innovations in the state had begun a conversation that made more 'radical' ideas seem possible. California tobacco control advocates are engaged in local endgame policy discussions and prepared to advance California's endgame goal.
