Summary of "Meta-analysis of mammary RNA seq datasets reveals the molecular understanding of bovine lactation biology."

The understanding of lactation biology at the gene expression level and the identification of candidate genes for milk synthesis and milk components are possible using recent advanced RNA seq technology. The purpose of this study is to understand the milk constituents synthesis, the molecular pathways responsible for milk synthesis and identification of candidate genes for milk production traits using whole mammary transcriptome dataset. We performed a meta-analysis of publically available RNA seq transcriptomics dataset of mammary tissue/milk somatic cells. Totally 11562 genes were commonly identified from all RNA seq based mammary gland transcriptomes. Functional annotation of commonly expressed genes revealed the molecular understanding of milk fat, protein and lactose synthesis process in mammary secretory cells and molecular pathways responsible for milk synthesis. Further, we identified several candidate genes responsible for milk production traits and constructed the gene regulatory network for RNA seq datasets. In conclusion, this study provides a basic understanding of lactation biology of cows at the gene expression level.

Medical and Biotech [MESH] Definitions

Meta-analysis of randomized trials in which estimates of comparative treatment effects are visualized and interpreted from a network of interventions that may or may not have been evaluated directly against each other. Common considerations in network meta-analysis include conceptual and statistical heterogeneity and incoherence.

Works consisting of studies using a quantitative method of combining the results of independent studies (usually drawn from the published literature) and synthesizing summaries and conclusions which may be used to evaluate therapeutic effectiveness, plan new studies, etc. It is often an overview of clinical trials. It is usually called a meta-analysis by the author or sponsoring body and should be differentiated from reviews of literature.

The molecular designing of drugs for specific purposes (such as DNA-binding, enzyme inhibition, anti-cancer efficacy, etc.) based on knowledge of molecular properties such as activity of functional groups, molecular geometry, and electronic structure, and also on information cataloged on analogous molecules. Drug design is generally computer-assisted molecular modeling and does not include pharmacokinetics, dosage analysis, or drug administration analysis.

MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.

The field of medicine concerned with understanding the biochemical basis of health and disease and involved in developing diagnostic and therapeutic methods that utilize MOLECULAR BIOLOGY techniques.
