O-9: The Central Role of Mitochondrial Function in Quality of Human Oocyte
Background: Mitochondria are the most aboudent and small essential organelles found in eukaryotic cells. These are semiautonomous organelles for the production of cellular ATP that through its various biochemical pathways. The primary pathway for ATP production is OXPHOS via the electron transfer chain (ETC) which is encoded by nuclear DNA and mtdna genomes. Mitochondria consist of double stran...
متن کاملRearrangements of human mitochondrial DNA (mtDNA): new insights into the regulation of mtDNA copy number and gene expression.
Mitochondria from patients with Kearns-Sayre syndrome harboring large-scale rearrangements of human mitochondrial DNA (mtDNA; both partial deletions and a partial duplication) were introduced into human cells lacking endogenous mtDNA. Cytoplasmic hybrids containing 100% wild-type mtDNA, 100% mtDNA with partial duplications, and 100% mtDNA with partial deletions were isolated and characterized. ...
متن کاملMitochondrial transcription factor A regulates mtDNA copy number in mammals.
Mitochondrial DNA (mtDNA) copy number regulation is altered in several human mtDNA-mutation diseases and it is also important in a variety of normal physiological processes. Mitochondrial transcription factor A (TFAM) is essential for human mtDNA transcription and we demonstrate here that it is also a key regulator of mtDNA copy number. We initially performed in vitro transcription studies and ...
متن کاملO-38: Concurrent Whole-Genome Haplotyping and Copy-Number Profiling of Single Cells
Background Methods for haplotyping and DNA copynumber typing of single cells are paramount for studying genomic heterogeneity and enabling genetic diagnosis. Before analyzing the DNA of a single cell by microarray or next-generation sequencing, a whole-genome amplification (WGA) process is required, but it substantially distorts the frequency and composition of the cell’s alleles. As a conseque...
متن کاملQuantification of Protein Copy Number in Yeast: The NAD+ Metabolome
Saccharomyces cerevisiae is calorie-restricted by lowering glucose from 2% to 0.5%. Under low glucose conditions, replicative lifespan is extended in a manner that depends on the NAD+-dependent protein lysine deacetylase Sir2 and NAD+ salvage enzymes. Because NAD+ is required for glucose utilization and Sir2 function, it was postulated that glucose levels alter the levels of NAD+ metabolites th...
