The deep neural network model is based on translating protein sequences and structural information into a musical score that features different pitches for each of the amino acids, and variations in note length and note volume reflecting secondary structure information and information about the chain length and distinct protein molecules. We train a deep learning model whose architecture is composed of several long short-term memory units from data consisting of musical representations of proteins classified by certain features, focused here on alpha-helix rich proteins. Using the deep learning model, we then generate de novo musical scores and translate the pitch information and chain lengths into sequences of amino acids. We use a Basic Local Alignment Search Tool to compare the predicted amino acid sequences against known proteins, and estimate folded protein structures using the Optimized protein fold RecognitION method (ORION) and MODELLER. We find that the method proposed here can be used to design de novo proteins that do not exist yet, and that the designed proteins fold into specified secondary structures. We validate the newly predicted protein by molecular dynamics equilibration in explicit water and subsequent characterization using a normal mode analysis. The method provides a tool to design novel protein materials that could find useful applications as materials in biology, medicine, and engineering. © Author(s).Plasma exchange (PE), which directly removes some plasma thyroid hormones, is a treatment option for thyroid storm. However, the effect of PE has not been accurately assessed yet. Here we assessed the effect of PE in a patient with thyroid storm while taking into consideration the distribution of thyroid hormones in the extravascular space. A 51-year-old woman with thyroid storm underwent 2 PE procedures at our hospital. By measuring changes in thyroid hormone levels in plasma, fresh frozen plasma (FFP) used, and waste fluid during each 2.5-hour PE procedure, we calculated the efficiency of thyroid hormone removal based on the hypothesis that total thyroid hormone content before and after PE is the same. During the patient's first PE procedure, the estimated thyroxine (T4) balance in the extravascular space (ΔX) was -70 μg, which corresponds to approximately 19% of T4 in the waste fluid. During the second PE procedure, ΔX was -131 μg, which corresponds to approximately 52% of T4 in the waste fluid. These data indicated that the source of removed T4 during PE varies. Linsitinib solubility dmso The amount of T4 removed from the extravascular space should be taken into account during assessment of the effect of PE in thyroid storm. © Endocrine Society 2020.Breast cancer research has traditionally centred on genomic alterations, hormone receptor status and changes in cancer-related proteins to provide new avenues for targeted therapies. Due to advances in next generation sequencing technologies, there has been the emergence of long, non-coding RNAs (lncRNAs) as regulators of normal cellular events, with links to various disease states, including breast cancer. Here we describe our bioinformatic analyses of a previously published RNA sequencing (RNA-seq) dataset to identify lncRNAs with altered expression levels in a subset of breast cancer cell lines. Using a previously published RNA-seq dataset of 675 cancer cell lines, a subset of 18 cell lines was selected for our analyses that included 16 breast cancer lines, one ductal carcinoma in situ line and one normal-like breast epithelial cell line. Principal component analysis demonstrated correlation with well-established categorisation methods of breast cancer (i.e. luminal A/B, HER2 enriched and basal-like A/B). Through detailed comparison of differentially expressed lncRNAs in each breast cancer sub-type with normal-like breast epithelial cells, we identified 15 lncRNAs with consistently altered expression, including three uncharacterised lncRNAs. Utilising data from The Cancer Genome Atlas (TCGA) and The Genotype Tissue Expression (GETx) project via Gene Expression Profiling Interactive Analysis (GEPIA2), we assessed clinical relevance of several identified lncRNAs with invasive breast cancer. Lastly, we determined the relative expression level of six lncRNAs across a spectrum of breast cancer cell lines to experimentally confirm the findings of our bioinformatic analyses. Overall, we show that the use of existing RNA-seq datasets, if re-analysed with modern bioinformatic tools, can provide a valuable resource to identify lncRNAs that could have important biological roles in oncogenesis and tumour progression. © 2020 Production and hosting by Elsevier B.V. on behalf of KeAi Communications Co., Ltd.The 31- and 32-nt 5'-fragment of Y4-RNA (Y4RNAfr) exists abundantly in human peripheral blood plasma. Although physiological roles of the plasma Y4RNAfr are not well established, its potential utility as a diagnostic/prognostic marker for acute coronary syndrome was suggested. In this paper, to establish a normal range of the Y4RNAfr level in plasma, we measured plasma Y4RNAfr levels of 40 healthy persons using the method we have developed, and compared them with other blood test data. From the obtained data, we tentatively regarded less then 0.1 fmol/ng as normal for the Y4RNAfr level in peripheral blood plasma. And the white blood cell count (WBC) and the C-reactive protein (CRP) level showed moderate positive correlations with the Y4RNAfr level, suggesting that Y4RNAfr could be a potential novel inflammatory marker. We also measured the Y4RNAfr level in peripheral blood plasma from four multiple myeloma patients. The plasma Y4RNAfr level was abnormal in all four myeloma patients, and the levels for two patients were far beyond the normal level. The WBC for each patient was normal and the CRP levels for two patients were normal. These observations together suggest that a high level of Y4RNAfr in peripheral blood plasma and a normal WBC could be indicative of multiple myeloma. © 2020 Production and hosting by Elsevier B.V. on behalf of KeAi Communications Co., Ltd.
