Differential chromatin binding of the lung lineage transcription factor NKX2-1 resolves opposing murine alveolar cell fates in vivo.

Nat Commun 2021 05 4;12(1):2509. Epub 2021 May 4.

Department of Pulmonary Medicine, The University of Texas MD Anderson Cancer Center, Houston, TX, USA.

Differential transcription of identical DNA sequences leads to distinct tissue lineages and then multiple cell types within a lineage, an epigenetic process central to progenitor and stem cell biology. The associated genome-wide changes, especially in native tissues, remain insufficiently understood, and are hereby addressed in the mouse lung, where the same lineage transcription factor NKX2-1 promotes the diametrically opposed alveolar type 1 (AT1) and AT2 cell fates. Here, we report that the cell-type-specific function of NKX2-1 is attributed to its differential chromatin binding that is acquired or retained during development in coordination with partner transcriptional factors.

Sexual Minorities who Reject an LGB Identity: Who Are They and Why Does It Matter?

Issues Law Med 2021 ;36(1):27-43

Salt Lake City, Utah, United States.

Although some persons with minority sexual orientations do not identify as lesbian, gay, or bisexual (LGB), Minority Stress Theory (Meyer, 2003) has largely been developed utilizing LGB-identified samples. We examined a sample ( = 274) of sexual minorities with diverse religious and sexual identity labels to determine if those rejecting versus adopting an LGB identity were different in terms of religious, sexual, relational, and health characteristics. Results suggested those who reject an LGB identity are more likely to be religiously active, full members of their church, and highly intrinsic and theologically conservative in their religious viewpoint.

Node Centrality Measures Identify Relevant Structural MRI Features of Subjects with Autism.

Brain Sci 2021 Apr 14;11(4). Epub 2021 Apr 14.

National Institute for Nuclear Physics (INFN), Bologna Division, I-40127 Bologna, Italy.

Autism spectrum disorders (ASDs) are a heterogeneous group of neurodevelopmental conditions characterized by impairments in social interaction and communication and restricted patterns of behavior, interests, and activities. Although the etiopathogenesis of idiopathic ASD has not been fully elucidated, compelling evidence suggests an interaction between genetic liability and environmental factors in producing early alterations of structural and functional brain development that are detectable by magnetic resonance imaging (MRI) at the group level. This work shows the results of a network-based approach to characterize not only variations in the values of the extracted features but also in their mutual relationships that might reflect underlying brain structural differences between autistic subjects and healthy controls.

Prokaryotic taxonomy and nomenclature in the age of big sequence data.

ISME J 2021 Apr 6. Epub 2021 Apr 6.

Australian Centre for Ecogenomics, School of Chemistry and Molecular Biosciences, The University of Queensland, Brisbane, QLD, Australia.

The classification of life forms into a hierarchical system (taxonomy) and the application of names to this hierarchy (nomenclature) is at a turning point in microbiology. The unprecedented availability of genome sequences means that a taxonomy can be built upon a comprehensive evolutionary framework, a longstanding goal of taxonomists. However, there is resistance to adopting a single framework to preserve taxonomic freedom, and ever increasing numbers of genomes derived from uncultured prokaryotes threaten to overwhelm current nomenclatural practices, which are based on characterised isolates.

Computer-aided diagnosis of masses in breast computed tomography imaging: deep learning model with combined handcrafted and convolutional radiomic features.

J Med Imaging (Bellingham) 2021 Mar 29;8(2):024501. Epub 2021 Mar 29.

Radboud University Medical Center, Department of Medical Imaging, Nijmegen, The Netherlands.

A computer-aided diagnosis (CADx) system for breast masses is proposed, which incorporates both handcrafted and convolutional radiomic features embedded into a single deep learning model. The model combines handcrafted and convolutional radiomic signatures into a multi-view architecture, which retrieves three-dimensional (3D) image information by simultaneously processing multiple two-dimensional mass patches extracted along different planes through the 3D mass volume. Each patch is processed by a stream composed of two concatenated parallel branches: a multi-layer perceptron fed with automatically extracted handcrafted radiomic features, and a convolutional neural network, for which discriminant features are learned from the input patches.
