Snow White and the Seven Dwarfs: a fairytale for endocrinologists.

Endocr Connect 2021 Apr 1. Epub 2021 Apr 1.

S Livadas, Endocrine Unit, Athens Medical Centre, Athens, 10563, Greece.

'Snow White and the Seven Dwarfs', a fairytale that is widely known across the Western world, was originally written by the Brothers Grimm, and published in 1812. Though each dwarf was first given an individual name in the 1912 Broadway play by the same title, in Walt Disney's 1937 film 'Snow White and the Seven Dwarfs', they were renamed, and their names have become household words. As it is well known, myths, fables, and fairytales, though appearing to be merely children's tales about made-up and magical beings and places, have, more often than not, originated from real facts.

Biofactors 2021 Apr 20. Epub 2021 Apr 20.

Centro Andaluz de Biología del Desarrollo, Universidad Pablo de Olavide-CSIC-JA, Sevilla, Spain.

Coenzyme Q (CoQ ) deficiency is a rare disease characterized by a decreased accumulation of CoQ in cell membranes. Considering that CoQ synthesis and most of its functions are carried out in mitochondria, CoQ deficiency cases are usually considered a mitochondrial disease. A relevant feature of CoQ deficiency is that it is the only mitochondrial disease with a successful therapy available, the CoQ supplementation. Read More

Transcriptome-wide investigation of stop codon readthrough in Saccharomyces cerevisiae.

PLoS Genet 2021 Apr 20;17(4):e1009538. Epub 2021 Apr 20.

Department of Microbiology and Physiological Systems, University of Massachusetts Medical School, Worcester, Massachusetts, United States of America.

Translation of mRNA into a polypeptide is terminated when the release factor eRF1 recognizes a UAA, UAG, or UGA stop codon in the ribosomal A site and stimulates nascent peptide release. However, stop codon readthrough can occur when a near-cognate tRNA outcompetes eRF1 in decoding the stop codon, resulting in the continuation of the elongation phase of protein synthesis. At the end of a conventional mRNA coding region, readthrough allows translation into the mRNA 3'-UTR. Read More

Robust Estimation of Upscaling Factor on Double JPEG Compressed Images.

IEEE Trans Cybern 2021 Apr 20;PP. Epub 2021 Apr 20.

As one of the most important topics in image forensics, resampling detection has developed rapidly in recent years. However, the robustness to JPEG compression is still challenging for most classical spectrum-based methods, since JPEG compression severely degrades the image contents and introduces block artifacts in the boundary of the compression grid. In this article, we propose a method to estimate the upscaling factors on double JPEG compressed images in the presence of image upscaling between the two compressions. Read More

Saliency-Based Multilabel Linear Discriminant Analysis.

IEEE Trans Cybern 2021 Apr 20;PP. Epub 2021 Apr 20.

Linear discriminant analysis (LDA) is a classical statistical machine-learning method, which aims to find a linear data transformation increasing class discrimination in an optimal discriminant subspace. Traditional LDA sets assumptions related to the Gaussian class distributions and single-label data annotations. In this article, we propose a new variant of LDA to be used in multilabel classification tasks for dimensionality reduction on original data to enhance the subsequent performance of any multilabel classifier.

KenDTI: an ensemble model based on network integration and CNN for drug-target interaction prediction.

IEEE/ACM Trans Comput Biol Bioinform 2021 Apr 20;PP. Epub 2021 Apr 20.

The identification of drug-target interactions (DTIs) is an essential step in the process of drug discovery. As experimental validation suffers from high cost and low success rate, various computational models have been exploited to infer potential DTIs. The performance of DTI prediction depends heavily on the features extracted from drugs and target proteins. Read More

-Analysis of the Multi-Omics Data Identified the Ataxia Telangiectasia Mutated Gene as a Potential Biomarker of Breast Invasive Carcinoma.

Genet Test Mol Biomarkers 2021 Apr;25(4):263-275

Department of Biotechnology, Institute of Biochemistry, Biotechnology and Bioinformatics, The Islamia University of Bahawalpur, Bahawalpur, Pakistan.

The elevated global burden of the breast invasive carcinoma (BRIC) and lack of appropriate biomarkers for its early detection and treatment requires extensive investigation to enhance understanding regarding BRIC associated molecular alterations. Ataxia telangiectasia mutated () is a multifunctional tumor suppressor gene, which participates in the DNA damage response pathway and cellular checkpoint activation. Several studies have reported the reduction of expression as a reliable biomarker of BRIC. Read More
