An Information Entropy-Based Approach for Computationally Identifying Histone Lysine Butyrylation

Butyrylation plays a crucial role in the cellular processes. Due to limit of techniques, it is a challenging task to identify histone butyrylation sites on a large scale. To fill the gap, we propose an approach based on information entropy and machine learning for computationally identifying histone butyrylation sites. The proposed method achieves 0.92 of area under the receiver operating characteristic (ROC) curve over the training set by 3-fold cross validation and 0.80 over the testing set by independent test. Feature analysis implies that amino acid residues in the down/upstream of butyrylation sites would exhibit specific sequence motif to a certain extent. Functional analysis suggests that histone butyrylation was most possibly associated with four pathways (systemic lupus erythematosus, alcoholism, viral carcinogenesis and transcriptional misregulation in cancer), was involved in binding with other molecules, processes of biosynthesis, assembly, arrangement or disassembly and was located in such complex as consists of DNA, RNA, protein, etc. The proposed method is useful to predict histone butyrylation sites. Analysis of feature and function improves understanding of histone butyrylation and increases knowledge of functions of butyrylated histones.

(CNN) — Google users in the United States had a lot of questions about blood pressure, the keto diet and hiccups in 2019. Those topics were among the 10 most-searched health-related questions on the search engine this year, according to new data from Google. The list was based on search terms collected between January and early December. Last year, the top health-related questions Googled by people in the US included what is amyotrophic lateral sclerosis, or ALS, what is endometriosis and how long does weed stay in your urine. In 2017, what is lupus, how long does the flu last and what causes hiccups were some of the...

Conclusion: The expression of lncRNAs is abnormal in the kidney of LN. LncRNA RP11-2B6.2 is a novel positive regulator of IFN-I pathway through epigenetic inhibition of SOCS1, which provides a new therapeutic target to alleviate over-activated IFN-I signaling in LN. Introduction Systemic lupus erythematosus (SLE) is a heterogeneous autoimmune disorder characterized by the occurrence of a wide range of autoantibodies and organ damage and predominantly affects women at childbearing age (1, 2). Lupus nephritis (LN) is considered one of the most prevalent and serious complications of SLE with high morbidity and mortali...

Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...

Conclusion This paper summarizes the current findings regarding the anti-colitis activity of plant-derived alkaloids and shows how these alkaloids exhibit significant and beneficial effects in alleviating colonic inflammation. These natural alkaloids are not only promising agents for IBD treatment but are also components for developing new wonder drugs. However, the underlying molecular mechanisms or toxicological evaluation of most plant-derived alkaloids still require much scientific research, and their actual efficacies for IBD patients have not been verified well in field research. Thus, further clinical trials to elu...

In this study, we collected a comprehensive multi-dimensional data from GWAS, gene expression, and methylation studies and generated transcriptome-wide association study (TWAS) data to further interpret the GWAS association results. We applied our previously developed method called mega-analysis of Odds Ratio (MegaOR) to prioritize CD candidate genes (CDgenes). As a result, we identified consensus sets of CDgenes (62–235 genes) based on the evidence matrix. We demonstrated that these CDgenes were significantly more frequently interact with each other than randomly expected. Functional annotation of these genes highli...

Conclusion An integrating computational case study, which involves molecule docking, MD simulations, ensemble docking, MM/GB(PB)SA binding free energy calculations and decompositions, has been conducted toward type I1/2 NIK inhibitors to further illuminate their binding mechanisms. As conventional RRD docking methods and IFD cannot well reflect the relative activity, ensemble docking by using MRCs is adopted and the docking result is largely improved, suggesting that protein flexibility is vitally important in type I1/2 inhibitors binding. Then, MD simulations combined with MM/GB(PB)SA binding free energy calculations are...

Discussion Flushing is usually thought of as a benign condition such as blushing, but can be quite irritating if it is frequent or persistent (i.e. menopausal hot flashes) or even pathologic (i.e. malignancy). “Flushing is a subjective and sensation of warmth that is accompanied by reddening of the skin anywhere on the body but favors the face, neck, and upper torso…. Flushing can be broadly divided into episodic or persistent. Episodic flashing is mediated by the release of endogenous vasoactive mediators or medications, while persistent flushing result in a fixed facial erythema with telangiectasias and cyan...

BY UWE REINHARDT In tribute to Uwe we are re-running this instant classic from THCB’s archives. Originally published on Jan 31, 2017. Everyone knows (or should know) that forcing a commercial health insurer to write for an individual a health insurance policy at a premium that falls short of the insurer’s best ex ante estimate of the cost of health care that individual will require is to force that insurer into what economists might call an unnatural act. Remarkably, countries that rely on competing private health insurers to operate their universal, national health insurance systems all do just that. They a...

As our waistlines thicken and our activity levels decrease, another chronic illness threatens to disturb our comfortable lifestyles. And, because it ’s relatively unknown, diagnosis comes as a shock to patients, who usually associate liver disease with heavy consumption of alcohol.Non-alcoholic steatohepatitis (NASH) is an advanced form of non-alcoholic fatty liver disease (NAFLD), where fat accumulates in the liver. It is most commonly associated with obesity, insulin resistance, metabolic syndrome and/or genetic polymorphisms, and is aggravated by inflammation and fibrosis.  First identified in the 1980s, its ...
