Classification of Neurotransmitters

Classification of Neurotransmitters

Neurotransmitters play a crucial role in the communication between neurons in the autonomic nervous system. Neurons in the autonomic nervous system can be cholinergic or adrenergic depending on the neurotransmitters synthesized. Cholinergic neurons use acetylcholine as their primary neurotransmitter. This includes all the preganglionic fibers of the sympathetic and pre- and postganglionic fibers of the parasympathetic nervous systems. In addition, neurons of the somatic nervous system also use...

Classification of Epithelial Tissues: Overview

Classification of Epithelial Tissues: Overview

Epithelial tissues are classified according to the shape of the cells and the number of cell layers formed. Cell shapes can be squamous (flattened and thin), cuboidal (square-like, as wide as it is tall), or columnar (rectangular, taller than it is wide). Additionally, the nucleus shape helps identify the type of epithelial cells. Squamous cells have flattened disc-shaped nuclei, cuboidal cells have spherical nuclei, and columnar cells have elongated nuclei.
Based on the number of cell layers,...

Classification of Epithelial Tissues: Stratified Epithelium

Classification of Epithelial Tissues: Stratified Epithelium

Stratified epithelium consists of several stacked layers of cells. They provide the durability to withstand constant physical and chemical attacks. Stratified epithelium is named after the shape of the most apical layer of cells. Stratified squamous epithelium is the most common type found in the human body. In this tissue, the apical cells are squamous, whereas the basal layer contains either columnar or cuboidal cells. The basal cells divide to form new daughter cells, which gradually become...

Background:

Breast cancer exhibits high prevalence, necessitating the identification of intrinsic subtype differences to elucidate underlying mechanisms.
Integrating multi-omics data offers a promising strategy to enhance the accuracy of breast cancer subtype classification.

Purpose of the Study:

To develop and evaluate DeepMO, a deep neural network model for classifying breast cancer subtypes using integrated multi-omics data.
To compare the performance of DeepMO against other methods using single-omics and multi-omics data.

Main Methods:

Collected mRNA, DNA methylation, and copy number variation (CNV) data from The Cancer Genome Atlas (TCGA).
Developed DeepMO, a deep neural network model comprising encoding and classification subnetworks for multi-omics data integration.
Applied feature selection techniques to identify significant genes and analyzed their enrichment in Gene Ontology (GO) terms and biological pathways.

Main Results:

DeepMO achieved superior accuracy and Area Under the Curve (AUC) in binary classification tasks compared to existing methods.
DeepMO demonstrated higher prediction accuracy in multi-classification tasks than single-omics and other multi-omics approaches.
Feature selection significantly impacted DeepMO's performance, and identified genes were associated with relevant biological processes.

Conclusions:

DeepMO provides an effective framework for breast cancer subtype classification by leveraging multi-omics data integration.
The model's ability to identify significant genes offers insights into breast cancer biology and potential therapeutic targets.
DeepMO represents a valuable tool for advancing multi-omics data analysis in cancer research.
