Especially, some significant genes such as RELA, LAMA4, PPBP were found play certain roles in the injury of BBB and the change of permeability in AD patients, thus leading to the change of immune microenvironment in AD brain.Towards repairing bone defects, calcium sulfate and calcium phosphate cement have been recognized as promising bone grafts. However, the current bone cements are generally lack of proper porosity for cell migration and new tissue formation. On the other hand, porous scaffold cannot be delivered by injection, which limits its use its clinical use. Herein, we develop a novel tricalcium phosphate/calcium sulfate granule to overcome the limitations of injectable cements and traditional scaffolds. The biocompatible granule underwent in situ self-setting to form scaffold with porous structure after injection. It contributes to calcium deposition and upregulation of osteogenic genes of mesenchymal stem cells in a time-dependent manner. Within three months, cavitary bone defects of distal rabbit femurs implanted the granules exhibited better bone formation than those with those implanted with autologous bone.Hypoxia-inducible factor 2 (HIF-2), is essential for cellular response to hypoxia and holds an important role in erythropoiesis, angiogenesis, tissue invasion and metastasis, thus, constituting an important therapeutic target. Maximal HIF-2 transcriptional activation requires HIF-2α phosphorylation by ERK1/2 that impairs its CRM1-mediated nuclear export. Herein, we reveal a novel interaction of HIF-2α with Reptin52, a multifunctional protein involved in cellular functions orchestrated both in the nucleus and the cytoplasm. HIF-2α and Reptin52 interact both in nuclear and cytoplasmic fractions, however, ERK1/2 pathway inactivation seems to favour their association in the cytoplasm. Notably, we demonstrate that Reptin52 reduces HIF-2 transcriptional activity, which results in decreased EPO secretion under hypoxia, by impairing HIF-2α stability via a non-canonical PHD-VHL-proteasome independent mechanism. This interaction represents a novel HIF-2 fine tuning mechanism that allows for distinct HIF1/2 isoforms regulation.Gastric cancer (GC) is the most common cancer worldwide. Although advances in the treatments, the oncogenic mechanisms are still largely unknown. RNF168 (ring-finger nuclear factor 168) is an important regulator of DNA double-strand break (DSB) repair, and its defects have been involved in the pathogenesis of a number of human diseases including cancer. However, its effects on GC are still unclear. In the study, we demonstrated that RNF168 expression was remarkably down-regulated in human GC tissues, and its low expression showed worse overall survival rate in GC patients. Importantly, we here reported that RNF168 directly interacted with Ras homolog gene family member C (RHOC) and induced its ubiquitination to promote RHOC degradation. RHOC exhibited higher expression in human GC tissues, and its knockdown significantly restrained cell proliferation, migration and invasion in GC cell lines. Moreover, RHOC knockdown led to a significant reduction in GC tumor growth in a xenograft mouse model. selleck products Additionally, histone deacetylase 1 (HDAC1) was found to be markedly decreased in GC cells with RHOC knockdown. Intriguingly, RHOC suppression-ameliorated proliferative and migratory ability in GC cells were significantly diminished by HDAC1 over-expression. Our in vivo studies finally confirmed that RHOC inhibition dramatically reduced the lung metastasis in nude mice. Collectively, all our results demonstrated that RNF168 directly interacted with RHOC to induce its degradation via promoting its ubiquitination, contributing to the inhibition of cell proliferation and metastasis in GC through decreasing HDAC1. Thus, targeting RNF168/RHOC/HDAC1 axis might be promising to develop effective therapies for GC treatment.Myocardial ischemia/reperfusion (MI/R) has high morbidity and mortality worldwide, but the underlying mechanisms have not been entirely understood. TRIM27 is one of the Tri-domain proteins (TRIM) family proteins with crucial roles in numerous life processes. In the study, we attempted to explore the effects of heart-conditional knockout of TRIM27 (TRIM27cKO) on MI/R progression both in vivo and in vitro. Our results showed that TRIM27 was strongly decreased in murine hearts with MI/R injury and in cardiomyocytes with hypoxic reoxygenation (HR) treatment. TRIM27cKO could further accelerate the infarction size and cardiac dysfunction in MI/R mice. Function study demonstrated that heart-selective TRIM27 deletion significantly aggravated apoptosis in hearts of MI/R mice through enhancing Caspase-3 activities. Moreover, inflammatory response due to MI/R injury was remarkably exacerbated in TRIM27cKO mice by strengthening nuclear factor κB (NF-κB) activation. In addition, p53 expression levels were dramatically up-regulated in hearts of MI/R mice and cardiomyocytes with HR treatment, which were further aggravated by TRIM27cKO. Intriguingly, we found that TRIM27 could interact with p53 and promote its ubquitination. Of note, suppressing p53 remarkably ameliorated TRIM27cKO-intensified apoptotic cell death and inflammation in HR-treated cardiomyocytes. Taken together, all these findings revealed that TRIM27/p53 axis may be involved in MI/R progression, and thus could be a therapeutic target for this disease treatment.

To provide real-world data on the impact of autologous hematopoietic stem cell transplantation (AHSCT) on treatment costs of patients with multiple sclerosis (MS) in Poland.

Medical data of 105 patients who underwent AHSCT in the years 2011 to 2016 were obtained from the National Health Fund (NHF) database. Treatment costs were calculated from the public payer’s perspective per patient-year for the total available period as well as 12 months before and after AHSCT. The statistical analysis was performed using MATLAB 2016b.

Mean treatment-related costs covered by the NHF per patient-year before and after the transplantation were €4314.9 and €1188.8 , respectively. The average cost of disease-modifying drugs per patient was reduced from €2497.9/year before to €65.3/year after AHSCT.

Although the initial cost of AHSCT is high, the costs involving AHSCT and post-AHSCT treatment could, according to our analysis, pay off in 3.9 years, when compared to the costs of disease-modifying drug therapy in aggressive MS.
