Drosophila Mitochondrial Genomics

Mitochondria are present in almost all cell types in animals, including humans. Cellular energy production depends on mitochondria for the production of ATP and metabolic by-products through oxidative phosphorylation (OXPHOS) and can be involved in a variety of life activities including respiratory chain energy supply, tissue development, apoptosis and innate immunity. Mitochondrial function depends on approximately 1200 - 1500 proteins, most of which are encoded by the nuclear genome and transported to the mitochondria, and therefore mitochondrial variation shows multiple patterns of inheritance.

Quantitative genetic and genomic approaches have been applied to identify the underlying nuclear genetic machinery, but studies on the function and variation of the maternally inherited mitochondrial genome are limited. Drosophila melanogaster is a powerful and genetically manageable model for studying mitochondrial genetics, and the Drosophila mitochondrial genome is conserved with that of humans.

CD BioSciences targets the cutting-edge research of mitochondrial genomics. Not only do we study the structural, functional and genetic characteristics of mitochondria through Drosophila, but we also use Drosophila genetic mutants to help our clients discover the mechanisms of multi-system dysfunctional diseases caused by mitochondrial variants, including neurodegenerative diseases (Parkinson, Alzheimer and Huntington disease), cardiovascular diseases, cancer and the aging process. CD BioSciences offers a total solution for mitochondrial genome (Mt genome) sequencing and analysis through Illumina and PacBio platforms.
