Nectar is the staple diet of adult mosquitoes in the wild, but its availability is inconsistent and can be affected by rainfall. In urban centers, Aedes vectors commonly use man-made containers as their major habitat; however, they can colonize any items replenished by rainfall. Garbage output has increased significantly in recent years, at a time when collection frequency is reducing. Such garbage usually includes organic components, some of which are sweet and can be fed upon by other animals or become can containers for rainwater...

Yin Yang 1 (YY1) regulates early embryogenesis and adult tissue formation. However, the role of YY1 in stem cell regulation remains unclear. YY1 has a Polycomb group (PcG) protein-dependent role in mammalian cells. The PcG-independent functions of YY1 are also reported, although their underlying mechanism is still undefined. This paper reports the role of YY1 and BAF complex in the OCT4-mediated pluripotency network in mouse embryonic stem cells (mESCs). The interaction between YY1 and BAF complex promotes mESC proliferation and pluripotency...

BACKGROUND: Adenosine triphosphate (ATP)-dependent chromatin remodeling SWI/SNF-like BAF and PBAF complexes have been implicated in the regulation of stem cell function and cancers. Several subunits of BAF or PBAF, including BRG1, BAF53a, BAF45a, BAF180, and BAF250a, are known to be involved in hematopoiesis. Baf200, a subunit of PBAF complex, plays a pivotal role in heart morphogenesis and coronary artery angiogenesis. However, little is known on the importance of Baf200 in normal and malignant hematopoiesis...

Variants affecting the function of different subunits of the BAF chromatin-remodelling complex lead to various neurodevelopmental syndromes, including Coffin-Siris syndrome. Furthermore, variants in proteins containing PHD fingers, motifs recognizing specific histone tail modifications, have been associated with several neurological and developmental-delay disorders. Here, we report eight heterozygous de novo variants (one frameshift, two splice site, and five missense) in the gene encoding the BAF complex subunit double plant homeodomain finger 2 (DPF2)...

Lepidic adenocarcinoma previously known as bronchioloalveolar carcinoma (BAC) is a non-small cell lung cancer with an indolent presentation. Bronchial anthracofibrosis (BAF) is caused by long-standing exposure to biomass fuel smoke often in poorly ventilated kitchen. Middle lobe syndrome (MLS) due to BAF is not uncommon however, lepidic adenocarcinoma then known as BAC, presenting as MLS has been documented only once before in the Polish literature. A 68-year-old never-smoker female with biomass fuel smoke exposure presented with cough and breathlessness...

We report on the toxicity and bioaccumulation of three different types of Cd-based quantum dots (QDs), dispersed in aqueous medium, for a model plant Allium cepa L. It is believed that encapsulation of nanoparticles should reduce their toxicity and increase their stability in different environments; in this work we studied how QD encapsulation affects their phytotoxicity. Core, core/shell, and core/shell/shell QDs (CdTe, CdTe/ZnS, and CdTe/CdS/ZnS QDs capped by 2-mercaptopropionic acid) were tested and CdCl2 was used as a positive control...

The human interferon (IFN)-induced MxA protein is a key antiviral host restriction factor exhibiting broad antiviral activity against many RNA viruses, including highly pathogenic avian influenza A viruses (IAV) of the H5N1 and H7N7 subtype. To date the mechanism for how MxA exerts its antiviral activity is unclear, however, additional cellular factors are believed to be essential for this activity. To identify MxA cofactors we performed a genome-wide siRNA-based screen in human airway epithelial cells (A549) constitutively expressing MxA using an H5N1 reporter virus...

In a previous study on discovering new antimicrobial agents from microbial sources, nine bafilomycins were isolated from the fermentation broth of Streptomyces albolongus. Among them, bafilomycin C1 (Baf C1) showed strong antifungal activity against Candida albicans, with MIC value of 1.56 μg/mL. The aim of this study was to evaluate the action mechanism of Baf C1 against C. albicans. Quantitative PCR analysis revealed that ergosterol biosynthesis-related genes of C. albicans ACS1, HMG1, IDI1, ERG1, ERG2, ERG6, ERG7, ERG8, ERG9, ERG12, ERG13, ERG20, ERG24, ERG251, ERG252, ERG26, ERG27, and ERG28 were all down-regulated (Log2fold change < -1) after Baf C1(4 μg/mL) exposure...

To activate or repress specific genes, chromatin is constantly modified by chromatin-remodeling complexes. Among these complexes, the SWItch/Sucrose Non-Fermenting (SWI/SNF) complex, also referred to as BRG1-Associated Factor (BAF) complex, moves the nucleosome along chromatin using energy provided by ATP hydrolysis. In mammalian organisms, the SWI/SNF complex is composed of 10-15 subunits, depending on cell type, and a defect in one of these subunits can have dramatic consequences. In this review we will focus on the alterations identified in the SWI/SNF (BAF) complex subunits that lead to cancerous pathologies...

The mammalian SWI/SNF chromatin remodeling complex is a heterogeneous collection of related protein complexes required for gene regulation and genome integrity. It contains a central ATPase (BRM or BRG1) and various combinations of 10-14 accessory subunits (BAFs for BRM/BRG1 Associated Factors). Two distinct complexes differing in size, BAF and the slightly larger Polybromo-BAF (PBAF), share many of the same core subunits but are differentiated primarily by having either AT-rich interaction domain 1A/B (ARID1A/B in BAF) or ARID2 (in PBAF)...

The secondary effluent from a petrochemical wastewater treatment plant was treated by biological aerated filter (BAF) before and after ozonation, namely BAF1 and BAF2, respectively. The results showed that BAF2 fed with the ozonized secondary effluent exhibited a high efficiency in degrading organic pollutants. The removal efficiency of COD and NH4-N was 6.0 ± 3.2 and 48.2~18.6% for BAF1 and 12.5 ± 5.8 and 62.1~40.9% for BAF2, respectively, during the whole operation. The integration system of ozonation and BAF could tolerate a higher organic loading rate...

Neural tube defects (NTD) are among the most common birth defects in humans and yet their molecular etiology remains poorly understood. NTD are believed to result from the complex interaction of environmental factors with a multitude of genetic risk factors in a classical multifactorial disease model. Mendelian forms of NTD in which single variants are sufficient to cause the disease are extremely rare. We report a monozygotic twin with severe NTD (occipital encephalocele and myelomeningocele) and a shared de novo likely truncating variant in SMARCC1...

Soft-tissue sarcomas are increasingly characterized and subclassified by genetic abnormalities that represent underlying drivers of their pathology. Hallmark tumor suppressor gene mutations and pathognomonic gene fusions collectively account for approximately one-third of all sarcomas. These genetic abnormalities most often result in global transcriptional misregulation via disruption of protein regulatory complexes which govern chromatin architecture. Specifically, alterations to mammalian SWI/SNF (mSWI/SNF or BAF) ATP-dependent chromatin remodeling complexes and Polycomb repressive complexes cause disease-specific changes in chromatin architecture and gene expression across a number of sarcoma subtypes...
