In accordance with this, we find that DDK inhibition caused premature mitotic entry resulting in mitotic abnormalities such as anaphase bridges, lagging chromosomes, and cells with >2 poles in Ewing sarcoma cells. This abnormal progression through mitosis resulted in mitotic catastrophe as evidenced by the formation of micronuclei and induction of DNA damage. Together, these findings suggest that DDK activity is required for the faithful and timely completion of DNA replication in Ewing cells and that DDK inhibition may present a viable therapeutic strategy for the treatment of Ewing sarcoma.Renal cell carcinoma (RCC) is a lethal urinary malignancy. Circular RNAs (circRNAs) contribute to the malignant phenotype and progression of several types of human cancers, including RCC. In this study, we identified relatively low hsa_circ_0060927 (circCYP24A1) expression in RCC tissue through high-throughput sequencing and RT-qPCR. Fluorescence in situ hybridization (FISH) was used to validate the expression and subcellular localization of circCYP24A1 in RCC tissues. CCK-8, Transwell, EdU, and wound-healing assays indicated that circCYP24A1 overexpression inhibited the proliferation, invasion, and migration of RCC cells. Dual-luciferase reporter, RNA immunoprecipitation (RIP), FISH, and RNA-pulldown assays verified that circCYP24A1 inhibited RCC progression by sponging miR-421, thus inducing CMTM-4 expression. Xenograft assays and metastasis models further indicated that circCYP24A1 significantly inhibited the metastasis and proliferation of RCC cells in vivo. Taken together, circCYP24A1 is a prognosis-related circRNA in RCC that functions through the circCYP24A1/miR-421/CMTM-4 axis to modulate RCC progression.Dynamic changes in physiologic oxygen are required for proper placenta development; yet, when low-oxygen levels persist, placental development is halted, culminating in preeclampsia (PE), a serious complication of pregnancy. Considering mitochondria's function is intimately linked to oxygen changes, we investigated the impact of oxygen on mitochondrial dynamics in placental mesenchymal stromal cells (pMSCs) that are vital for proper placental development. Transmission electron microscopy, proximity ligation assays for mitochondrial VDAC1 and endoplasmic reticulum IP3R, and immunoanalyses of p-DRP1 and OPA1, demonstrate that low-oxygen conditions in early 1st trimester and PE promote mitochondrial fission in pMSCs. Increased mitochondrial fission of mesenchymal cells was confirmed in whole PE placental tissue sections. Inhibition of DRP1 oligomerization with MDiVi-1 shows that low oxygen-induced mitochondrial fission is a direct consequence of DRP1 activation, likely via HIF1. Mitophagy, a downstream event prompted by mitochondrial fission, is a prominent outcome in PE, but not 1st trimester pMSCs. We also investigated whether mesenchymal-epithelial interactions affect mitochondrial dynamics of trophoblasts in PE placentae. Exposure of trophoblastic JEG3 cells to exosomes of preeclamptic pMSCs caused heightened mitochondrial fission in the cells via a sphingomyelin-dependent mechanism that was restored by MDiVi-1. Our data uncovered dichotomous regulation of mitochondrial fission and health in human placental mesenchymal cells under physiologic and pathologic hypoxic conditions and its impact on neighboring trophoblast cells.Childhood obesity leads to hippocampal atrophy and altered cognition. However, the molecular mechanisms underlying these impairments are poorly understood. The neurotrophic factor neuregulin-1 (NRG1) and its cognate ErbB4 receptor play critical roles in hippocampal maturation and function. This study aimed to determine whether exogenous NRG1 administration reduces hippocampal abnormalities and neuroinflammation in rats exposed to an obesogenic Western-like diet (WD). Lewis rats were randomly divided into four groups (12 rats/group) (1) control diet+vehicle (CDV); (2) CD + NRG1 (CDN) (daily intraperitoneal injections 5 μg/kg/day; between postnatal day, PND 21-PND 41); (3) WD + VEH (WDV); (4) WD + NRG1 (WDN). Neurobehavioral assessments were performed at PND 43-49. Brains were harvested for MRI and molecular analyses at PND 49. We found that NRG1 administration reduced hippocampal volume (7%) and attenuated hippocampal-dependent cued fear conditioning in CD rats (56%). NRG1 administration reduced PSD-95 proteinnerabilities observed in obese individuals.To develop inhibitors targeting DNA damage repair pathways is important to improve the effectiveness of chemo- and radiotherapy for cancer patients. Rad51 mediates homologous recombination (HR) repair of DNA damages. It is widely overexpressed in human cancers and overwhelms chemo- and radiotherapy-generated DNA damages through enhancing HR repair signaling, preventing damage-caused cancer cell death. Therefore, to identify inhibitors of Rad51 is important to achieve effective treatment of cancers. Transcription factor Nanog is a core regulator of embryonic stem (ES) cells for its indispensable role in stemness maintenance. In this study, we identified Nanog as a novel inhibitor of Rad51. It interacts with Rad51 and inhibits Rad51-mediated HR repair of DNA damage through its C/CD2 domain. Moreover, Rad51 inhibition can be achieved by nanoscale material- or cell-penetrating peptide (CPP)-mediated direct delivery of Nanog-C/CD2 peptides into somatic cancer cells. Furthermore, we revealed that Nanog suppresses the binding of Rad51 to single-stranded DNAs to stall the HR repair signaling. This study provides explanation for the high γH2AX level in unperturbed ES cells and early embryos, and suggests Nanog-C/CD2 as a promising drug candidate applied to Rad51-related basic research and therapeutic application studies.BACKGROUND Acute hemorrhagic leukoencephalitis (AHLE) is a very rare fulminant post-infectious demyelinating disease of the CNS. We report an atypical presentation of AHLE involving unique brain areas 2 weeks following a viral upper-respiratory tract infection (URTI). Early diagnosis and proper management improve the prognosis of this disease, and AHLE can have a very poor prognosis and high mortality rate. CASE REPORT A 52-year-old male patient was referred for deteriorating consciousness 2 weeks after a viral URTI. An initial brain CT scan showed multiple patchy bilateral and diffuse hypodense areas including the cerebellar, occipital, parietal, and frontal lobes. The diagnostic workup also included CSF analysis and MRI of the brain, which revealed multiple areas of hemorrhagic involvement. Management included broad-spectrum antibiotics, acyclovir, mannitol, steroids, and plasmapheresis. On the fifth day of admission, brain CT showed severe diffuse edema and brain herniation. Unfortunately, despite prompt aggressive treatment measures, within 48 hours the patient died due to centrally-mediated hemodynamic instability. CONCLUSIONS We report a rare case of AHLE with a unique presentation and extensive unusual involvement of regions of periventricular and subcortical white matter, cerebellum, and midbrain. Early diagnosis along with appropriate management measures and intensive care can help decrease morbidity and mortality; therefore, prompt referral and high-level care should be sought for all patients who present with acute deteriorating consciousness. We hope that this report can help future studies to better characterize this rare disease and provide further guidance regarding prognosis and management.BACKGROUND Although serum uric acid (SUA) levels have been reported to be associated with atrial fibrillation (AF), the specific associations remain unclear. The purpose of this study was to investigate the potential relationship of serum uric acid levels to atrial fibrillation. MATERIAL AND METHODS We retrospectively analyzed clinical data of 970 consecutive hospitalized patients (M/F, 519/451; age, 64.78±13.49 years). The study included 478 patients with AF, and 492 age-matched patients with sinus rhythm and no history of arrhythmia as a control group. The t test, ANOVA, chi-squared test, or Fisher exact test were performed to analyze clinical baseline data. RESULTS Compared with the control group, patients with AF exhibited higher SUA levels (5.66±1.90 vs 5.35±1.55 mg/dL, P=0.006), especially women (P less then 0.001). Pearson correlation analysis showed SUA was influenced by A/G, PAB, and APOA1 in patients with AF. Logistic regression analysis showed SUA was associated with AF (total OR=1.002, 95% CI 1.000-1.003; women OR=1.005, 95% CI 1.003-1.007). After adjustment for clinical related factors for AF, SUA was still associated with AF (total OR=1.004, 95% CI 1.002-1.006; women OR=1.005, 95% CI 1.002-1.009). DASA-58 in vitro Also, elevated SUA was positively correlated with A/G and PAB and negatively correlated with APOA1. There were no significant differences in SUA levels in AF subtypes and complications. CONCLUSIONS Elevated SUA levels were associated with AF, but the independent association was significant only in women. Elevated SUA may promote other AF-related factors and participate in the pathological process of AF.
Simulation-based boot camps have been evaluated by fellows as an effective way to learn, to improve self-confidence, and to prepare for new responsibilities. However, existing studies do not explore how boot camps may contribute to other critical aspects of trainee development. Our objective was to use qualitative research methodology to characterize trainees' experiences of boot camp and its impact on their professional development.
This study used a phenomenological framework to explore fellows' experience of boot camp. Semistructured phone interviews were conducted with first-year neonatology fellows after attending the Regional Neonatology Boot Camp. Interviews were transcribed and coded for themes. The authors continually evaluated the coding categories in an iterative process until consensus was reached.
Seventy-seven first-year neonatal-perinatal medicine fellows representing 16 fellowship programs participated in the Regional Neonatology Boot Camp in 2016 and 2017. Fifteen fellows from 10 institd integrate these elements into the curriculum to support PIF and explicitly state PIF as a learning objective.
To analyze the trends of glaucoma surgery procedures over the past 5 years among hospitals across major provinces in China.
This was a retrospective observational study based on medical records. We obtained the annual numbers of commonly performed glaucoma incisional surgeries from 57 hospitals of 30 provincial regions in the Chinese Glaucoma Study Consortium (CGSC) from January 2015 to September 2019. The trend of glaucoma surgery was analyzed by Cochrane-Armitage trend test.
Trabeculectomy, cataract extraction combined with goniosynechialysis, cataract extraction combined with trabeculectomy, and surgical peripheral iridotomy (SPI) were the top 4 surgical procedures percentages of which have the most substantial change over the course of 2015 to 2019 (all Ptrend <0.001). Numbers of trabeculectomies decreased significantly from 47.59% in 2015 to 31.21% in 2019; cataract extraction combined with goniosynechialysis increased from 12.12% to 28.48%; cataract extraction combined with trabeculectomy increased from 13.
