The Ir(I) complex [Ir(μ-Cl)(coe)2 ]2 (coe = cis- cyclooctene) is a catalyst precursor for benzene alkenylation using Cu(II) carboxylate salts. Using [Ir(μ-Cl)(coe)2 ]2 , propenylbenzenes are formed from the reaction of benzene, propylene, and CuX2 (X = acetate, pivalate, or 2-ethylhexanoate). The Ir-catalyzed reactions selectively produce anti-Markovnikov products, trans -β-methylstyrene, cis -β-methylstyrene, and allylbenzene, along with minor amounts of the Markovnikov product, α-methylstyrene...

Homeobox genes encode developmental transcription factors regulating tissue-specific differentiation processes and drive cancerogenesis when deregulated. Dendritic cells (DCs) are myeloid immune cells occurring as two types, either conventional or plasmacytoid DCs. Recently, we showed that the expression of NKL-subclass homeobox gene VENTX is restricted to conventional DCs, regulating developmental genes. Here, we identified and investigated homeobox genes specifically expressed in plasmacytoid DCs (pDCs) and derived blastic plasmacytoid dendritic cell neoplasm (BPDCN)...

Multimodal measurements have become widespread in genomics, however measuring open chromatin accessibility and splicing simultaneously in frozen brain tissues remains unconquered. Hence, we devised Single-Cell-ISOform-RNA sequencing coupled with the Assay-for-Transposase-Accessible-Chromatin (ScISOr-ATAC). We utilized ScISOr-ATAC to assess whether chromatin and splicing alterations in the brain convergently affect the same cell types or divergently different ones. We applied ScISOr-ATAC to three major conditions: comparing (i) the Rhesus macaque ( Macaca mulatta ) prefrontal cortex (PFC) and visual cortex (VIS), (ii) cross species divergence of Rhesus macaque versus human PFC, as well as (iii) dysregulation in Alzheimer's disease in human PFC...

The majority of neocortical projection neurons are generated indirectly from radial glial cells (RGCs) mediated by intermediate progenitor cells (IPCs) in mice. IPCs are thought to be a great breakthrough in the evolutionary expansion of the mammalian neocortex. However, the precise ratio of neuron production from IPCs and characteristics of RGC differentiation process are still unclear. Our study revealed that direct neurogenesis was seldom observed and increased slightly at late embryonic stage. Besides, we conducted retrovirus sparse labelling combined carboxyfluorescein diacetate succinimide ester (CFSE) and Tbr2-CreER strain to reconstruct individual lineage tree in situ...

The low photoluminescence (PL) efficiency and unstable features of small blue-emitting CsPbX3 nanocrystals (NCs) greatly limit their applications in optoelectronics field. Herein, the synergistic and post-treatment kinetics are studied to create highly bright and anomalous stable violet (peak position of ≈408 nm) and blue (peak position of ∼ 466 nm) emitting perovskite NCs. Ligand and ion exchange mechanism are systematic studied by the evolution of absorption, PL, and fluorescence lifetime to evaluate ligand bonding, defect engineering, and non-radiative recombination...

Rett syndrome (RTT) is a rare genetic neurodevelopmental disorder that has no cure apart from symptomatic treatments. While intense research efforts are required to fulfill this unmet need, the fundamental challenge is to obtain sufficient patient data. In this study, we used human transcriptomic data of four different sample types from RTT patients including induced pluripotent stem cells, differentiated neural progenitor cells, differentiated neurons, and postmortem brain tissues with an increasing in vivo-like complexity to unveil specific trends in gene expressions across the samples...

Self-assembly of CuX2 (X- = BF4 - , PF6 - , and SbF6 - ) with a pair of chiral bidentate ligands, (1 R, 2 S )-(+)- and (1 S, 2 R )-(-)-1-(nicotinamido)-2,3-dihydro-1 H -inden-2-yl-nicotinate ( r,s -L or s,r -L), in a mixture solvent including ethanol in a glass vessel gives rise to SiF6 2- -encapsulated Cu2 L4 chiral cage products. The SiF6 2- anion from the reaction of X- with SiO2 of the glass-vessel surface acts as a cage template or cage bridge. One of the products, [SiF6 @Cu2 (SiF6 )( s,r -L)4 ]·3CHCl3 ·4EtOH, is one of the most effective heterogeneous catalysts for the oxidation of 3,5-di- tert -butylcatechol...

Growth hormone receptor (GHR)-deficient pigs were generated using the CRISPR/Cas9 system to investigate the involvement of GHR-mediated growth hormone (GH) signaling in androgen-associated gene expression of hepatic drug metabolizing enzymes (DMEs) and drug transporters. We initially confirmed that no wild-type GHR mRNA was present in GHR-/- (GHR-KO) pigs; in addition, as previously reported, those pigs exhibited decreases in body weight and serum insulin-like growth factor-1 concentration and an increase in serum GH concentration compared with the levels in GHR-/+ and GHR+/+ pigs with a wild-type GHR mRNA...

Autism spectrum disorders (ASD) are polygenic multifactorial disorders influenced by environmental factors. ASD-related differential DNA methylation has been found in human peripheral tissues, such as placenta, paternal sperm, buccal epithelium, and blood. However, these data lack direct comparison of DNA methylation levels with brain tissue from the same individual to determine the extent that peripheral tissues are surrogates for behavior-related disorders. Here, whole genome methylation profiling at all the possible sites throughout the mouse genome (>25 million) from both brain and blood tissues revealed novel insights into the systemic contributions of DNA methylation to ASD...

BACKGROUND: Major depressive disorder (MDD) is a type of emotional dysfunction, and its pathogenesis has not been fully elucidated. Specifically, the key molecules in depression-related brain regions that are involved in this disease and their contributions to this disease are currently unclear. METHODS: GSE53987 and GSE54568 were selected from the Gene Expression Omnibus (GEO) database. The data were standardized to identify the common differentially expressed genes (DEGs) in the cortex of MDD patients in the two datasets...

INTRODUCTION: Bipolar disorder (BD) is a chronic mental illness characterized by recurrent episodes of mania and depression and associated with social and cognitive disturbances. Environmental factors, such as maternal smoking and childhood trauma, are believed to modulate risk genotypes and contribute to the pathogenesis of BD, suggesting a key role in epigenetic regulation during neurodevelopment. 5-hydroxymethylcytosine (5hmC) is an epigenetic variant of particular interest, as it is highly expressed in the brain and is implicated in neurodevelopment, and psychiatric and neurological disorders...

Synthetic routes to the crystallization of two new box-like complexes, [Au6 (Triphos)4 (CuBr2 )](OTf)5 ·(CH2 Cl2 )3 ·(CH3 OH)3 ·(H2 O)4 ( 1 ) and [Au6 (Triphos)4 (CuCl2 )](PF6 )5 ·(CH2 Cl2 )4 ( 2 ) (triphos = bis(2-diphenylphosphinoethyl)phenylphosphine), have been developed. The two centrosymmetric cationic complexes have been structurally characterized through single-crystal X-ray diffraction and shown to contain a CuX2 - (X = Br or Cl) unit suspended between two Au(I) centers without the involvement of bridging ligands...

We previously identified androgen-dependent sex differences in the mRNA expression of drug metabolizing enzymes (DMEs), including CYPs, sulfotransferases and uridine 5'-diphospho-glucuronosyltransferases, and drug transporters in the pig liver and kidney. To elucidate the mechanism for such sex differences in pigs, we herein focused on the key regulators cut-like homeobox 2 (Cux2), B-cell lymphoma 6 (Bcl6), and signal transducer and activator of transcription 5b (Stat5b), which are reported to be responsible for the sex-biased gene expression of Cyps in the mouse liver...

Longitudinal traits, such as milk production traits in dairy cattle, are featured by having phenotypic values at multiple time points, which change dynamically over time. In this study, we first imputed SNP chip (50-100K) data to whole-genome sequence (WGS) data in a Chinese Holstein population consisting of 6,470 cows. The imputation accuracies were 0.88 to 0.97 on average after quality control. We then performed longitudinal GWAS in this population based on a random regression test-day model using the imputed WGS data...

Repeat expansions in the C9orf72 gene are the most common genetic cause of amyotrophic lateral sclerosis and familial frontotemporal dementia (ALS/FTD). To identify molecular defects that take place in the dorsolateral frontal cortex of patients with C9orf72 ALS/FTD, we compared healthy controls with C9orf72 ALS/FTD donor samples staged based on the levels of cortical phosphorylated TAR DNA binding protein (pTDP-43), a neuropathological hallmark of disease progression. We identified distinct molecular changes in different cell types that take place during disease progression...

Gliomas are one of the most prevalent brain tumors. This study sought to elucidate the mechanism of CUX2 in glioma development via ADCY1. CUX2 and ADCY1 expression in glioma predicted by bioinformatics analysis. Subsequent to gain- and loss-of-function experiments in glioma cells, cell proliferation was tested by CCK8 and plate clone formation assays, and cell migration and invasion by Transwell assay. The binding between CUX2 and ADCY1 was examined with dual-luciferase gene reporter and ChIP assays. The xenograft mouse model was established to verify the effect of the CUX2/ADCY1 axis on glioma cell growth in vivo...

Formation of the unexpected hexafluorosilicate (SiF6 2- ) anion during crystallization via self-assembly in glassware is scrutinized. Self-assembly of M(BF4 )2 (M2+ = Cu2+ and Zn2+ ) with tridentate N-donors (L) in a mixture solvent including methanol in a glass vessel gives rise to an SiF6 2- -encapsulated Cu3 L4 double-decker cage and a Zn2 L4 cage, respectively. Induced reaction of CuX2 (X- = PF6 - and SbF6 - ) instead of Cu(BF4 )2 , with the tridentate ligands, produces the same species. The formation time of SiF6 2- is in the order of anions BF4 - < PF6 - < SbF6 - under the given reaction conditions...

BACKGROUND: We used a hybrid machine learning systems (HMLS) strategy that includes the extensive search for the discovery of the most optimal HMLSs, including feature selection algorithms, a feature extraction algorithm, and classifiers for diagnosing breast cancer. Hence, this study aims to obtain a high-importance transcriptome profile linked with classification procedures that can facilitate the early detection of breast cancer. METHODS: In the present study, 762 breast cancer patients and 138 solid tissue normal subjects were included...

Cancer cells, in which the RAS and PI3K pathways are activated, produce high levels of reactive oxygen species (ROS), which cause oxidative DNA damage and ultimately cellular senescence. This process has been documented in tissue culture, mouse models, and human pre-cancerous lesions. In this context, cellular senescence functions as a tumour suppressor mechanism. Some rare cancer cells, however, manage to adapt to avoid senescence and continue to proliferate. One well-documented mode of adaptation involves increased production of antioxidants often associated with inactivation of the KEAP1 tumour suppressor gene and the resulting upregulation of the NRF2 transcription factor...
