Germline GATA2 heterozygous mutations were identified as complex immunodeficiency and hematological syndromes characterized by cytopenia (monocytes, B-cells, NK-cells), susceptibility to mycobacterium, fungus, or Epstein-Barr virus (EBV) infection, and myelodysplastic syndrome (MDS)/acute myelogenous leukemia (AML) development. Herein, we report a patient with AML who had a fatal infection after allogeneic hematopoietic stem cell transplantation (HSCT) due to impaired immune reconstitution associated with GATA2 mutation. A 15-year-old man was diagnosed with AML with monosomy 7. His family history was negative for immunodeficiency and hematological disorders. He attained complete remission after HSCT from an HLA-identical sister. Post-HSCT examinations performed 15 months later revealed pancytopenia, especially monocytopenia and the absence of B and NK cells, resulting in the occurrence of donor-type MDS. Twenty-one months after HSCT, he developed central nervous system aspergillosis and finally died of the disease. Two months later (24 months after PBSCT), the donor was diagnosed with persistent EBV infection accompanied by MDS with multilineage dysplasia. Genetic analysis of GATA2 revealed a novel heterozygous mutation (c.1023_1026dupCGCC) in both siblings.  https://www.selleckchem.com/products/jib-04.html  GATA2 mutations were highly prevalent among adolescent MDS/AML patients with monosomy 7. Therefore, the screening of GATA2 mutations in relatives is necessary when performing HSCT from a relative donor.Adolescents' popularity and popularity goal have been shown to be related to their aggression and alcohol use. As intervention efforts increasingly aim to focus on prosocial alternatives for youth to gain status, it is essential to have a comprehensive understanding of how popularity and popularity goal are associated with aggression and substance use as well as prosocial behaviors over time. The current study examined the bidirectional associations of aggression (overt and relational aggression), alcohol use, and prosocial behavior with popularity and popularity goal in adolescence across 3 years using cross-lagged panel analyses. Participants were 839 Dutch adolescents (Mage = 13.36, SD = 0.98; 51.3% girls). The results indicated that popularity was consistently positively associated with popularity goal, but popularity goal did not significantly predict subsequent popularity. Popularity positively predicted elevated aggression and alcohol use, but lower levels of prosocial behavior. For the full sample, alcohol use and overt aggression in grade 7 both predicted subsequent popularity in grade 8. However, when considering gender differences, overt aggression no longer was a significant predictor of popularity. These results were discussed in terms of the dynamic interplay between popularity, popularity goal, and behaviors, and in terms of implications for prevention and intervention efforts.Deficiency of caspase recruitment domain-containing protein 9 (CARD9) is an autosomal recessive primary immunodeficiency disorder, which typically predisposes immunocompetent individuals to single fungal infections and multiple fungal infections are very rare. We study an otherwise healthy 48-year-old man, who had been admitted to our hospital diagnosed with deep dermatophytosis caused by Trichophyton rubrum for three times at 29, 33 and 48 years old, respectively. At the age of 39 years, he suffered from cutaneous mucormycosis due to Mucor irregularis. Moreover, he had a long history of superficial fungal diseases and occasional oral candidiasis. Whole-exome sequencing revealed two compound heterozygous splicing variants in CARD9 gene, c. 184 + 5 G > T and c. 951G > A, confirmed by Sanger sequencing. Patients with recurrent fungal infections especially invasive fungal infections in the absence of known immunodeficiencies should be tested for CARD9 mutations.Retinoblastoma (RB) is a common intraocular malignant tumor. The growing evidence has reported that circular RNAs (circRNAs) play critical roles in RB development. Therefore, the purpose of the study is to investigate the regulatory mechanism of circDHDDS in RB. The real-time quantitative polymerase chain reaction (RT-qPCR) assay was used to quantify the expression levels of circDHDDS, miR-361-3p, and WNT3A in RB tissues and cells (RPCs, Y-79, and WERI-Rb-1). The proliferation and cell cycle of RB cells were assessed by colony formation assay and flow cytometry assays, respectively. The migration and invasion of RB cells were measured by transwell assay. The protein expression levels of Nectin-3 (CD113), SOX2, Nanog, and WNT3A were measured by Western blot assay. The functional targets of circDHDDS and miR-361-3p were predicted by bioinformatics databases, and the dual-luciferase reporter assay was used to confirm the interaction relationship between miR-361-3p and circDHDDS or WNT3A. The functional role of circDHDDS silencing in vivo was evaluated by xenograft experiment. We found that circDHDDS was overexpressed in RB tissues and cells compared with normal retinas tissues and retinal pigment epithelial cells, correspondingly. Furthermore, silencing of circDHDDS impeded proliferation, migration, invasion, and induced cell cycle arrest in vitro, which were abolished by knockdown of miR-361-3p. The in vivo experiments also suggested that tumor growth was inhibited by knockdown of circDHDDS. Moreover, we also found that miR-361-3p specifically bound to WNT3A, and overexpression of miR-361-3p suppressed RB development by decreasing WNT3A expression. Summarily, circDHDDS, a molecule sponge of miR-361-3p, regulated the expression of WNT3A. Therefore, circDHDDS/miR-361-3p/WNT3A axis stimulated the development of RB by regulation of proliferation, cell cycle program, migration, and invasion of RB cells.Low sensitivity of cancer stem cells toward regular cancer therapy strategies is an important issue in the field of cancer remedy. The concept of cancer stem cell elimination has been a topic of interest in the field of molecular medicine for a long time. At the current study, it was aimed to elevate the sensitivity of cancer stem-like cells toward radiotherapy by treating with Oct4-Sox2 complex decoy oligodeoxynucleotides (ODNs). After treating HT29 and HT29-ShE cells with Oct4-Sox2 complex decoy ODNs, and analyzing the cellular uptake and localization of decoys, treated cells and control groups were subjected to irradiation by fractionated 6MV X-ray with a final dose of 2 Gy. Thereafter, the influence of radiotherapy on ODNs treated groups and control group was investigated on cell viability, cell cycle, apoptosis, colonosphere formation and scratch assay. Cellular uptake and localization assays demonstrated that decoy ODNs can efficiently be transfected to the cells and reside in subcellular compartment, where they pose their action on gene regulation.
