Differential Expression of RNAseq Imprinted Genes from Bovine Females Before and After Puberty.

The productivity of beef cows depends on early reproduction traits such as puberty and has an economic impact on the efficiency of production system. Imprinted genes modulate many important endocrine processes such as growth, the onset of puberty and maternal reproductive and behavior. The role of imprinted genes in puberty is a challenging subject since they show the reciprocal role of maternal and paternal genomes in progeny.

In silico characterization of fructosyl peptide oxidase properties from Eupenicillium terrenum.

Fructosyl peptide oxidase (FPOX) enzyme from Eupenicillium terrenum has a high potential to be applied as a diagnostic enzyme. The aim of the present study is the characterization of FPOX from E. terrenum using different bioinformatics tools.

Survival prognostic factors in patients with acute myeloid leukemia using machine learning techniques.

This paper identifies prognosis factors for survival in patients with acute myeloid leukemia (AML) using machine learning techniques. We have integrated machine learning with feature selection methods and have compared their performances to identify the most suitable factors in assessing the survival of AML patients. Here, six data mining algorithms including Decision Tree, Random Forrest, Logistic Regression, Naive Bayes, W-Bayes Net, and Gradient Boosted Tree (GBT) are employed for the detection model and implemented using the common data mining tool RapidMiner and open-source R package.

Heterologous expression, purification, and refolding of SRY protein: role of L-arginine as analyzed by simulation and practical study.

Escherichia coli is a widely-used cell factory for recombinant protein production, nevertheless, high amount of produced protein is seen in aggregated form. The purpose of this study was to improve the solubility of recombinant bovine sex-determining region Y protein (rbSRY) by exploring the effect of temperature, inducer, and water-arginine mixed solvent. Codon-optimized rbSRY expressed in Rosetta-gami B (DE3) pLysS and purified by NI-NTA His-select affinity chromatography in the native and denaturing conditions.

Genome imprinting in stem cells: A mini-review.

Genomic imprinting is an epigenetic process result in silencing of one of the two alleles (maternal or paternal) based on the parent of origin. Dysregulation of imprinted genes results in detectable developmental and differential abnormalities. Epigenetics erasure is required for resetting the cell identity to a ground state during the production of induced pluripotent stem (iPS) cells from somatic cells.

Characterization of bovine (Bos taurus) imprinted genes from genomic to amino acid attributes by data mining approaches.

Genomic imprinting results in monoallelic expression of genes in mammals and flowering plants. Understanding the function of imprinted genes improves our knowledge of the regulatory processes in the genome. In this study, we have employed classification and clustering algorithms with attribute weighting to specify the unique attributes of both imprinted (monoallelic) and biallelic expressed genes.

Attribute selection and model evaluation for the maternal and paternal imprinted genes in bovine (Bos Taurus) using supervised machine learning algorithms.

Imprinted genes display biased expression of paternal and maternal alleles in mammals. They are marked through epigenetic process during gametogenesis. Characterization of imprinted genes has expanded our understanding of the regulation and function of genes.
