MetabolomicsA Generalized Strategy to Kill Leukemic Cells by Targeting the Regulatory Systems Governing Mitochondrial Membrane Potential
Targeting mitochondria emerges as a promising anti-leukemia strategy, yet selective mitochondrial disruption remains challenging. Here, we identified elevated mitochondrial membrane potential (MMP) as a hallmark of leukemic transformation and chemotherapy-resistant cells, prompting screening for MMP...

MetabolomicsATAD3A has a scaffolding role regulating mitochondria inner membrane structure and protein assembly

The ATPase Family AAA Domain Containing 3A (ATAD3A), is a mitochondrial inner membrane protein conserved in metazoans. ATAD3A has been associated with several mitochondrial functions, including nucleoid organization, cholesterol metabolism, and mitochondrial translation. To address its primary ro...

MetabolomicsCholesterol maintains the degradative capacity of lysosomes during clearance and recycling of dysfunctional mitochondria
Efficient clearance and recycling of dysfunctional mitochondria through the robust catabolic activity of lysosomes is essential for cellular health. However, how membrane lipids contribute to maintaining the degradative capacity of lysosomes remains poorly understood. Here, we show that cholesterol ...

TranscriptomicsTo analyze the effect of loss of mitochondria on the transcriptome of Candida albicans
This set of experiment was done in order to analyze the effect of a dysfunctional mitochondria on C. albicans. The mutant was obtained by deleting the gene FZO1, which is known to be involved in mitochondrial biogenesis in S. cerevisiae. We show that the deletion of FZO1 leads to a change in mitocho...

TranscriptomicsTranscription profiling of lung carcinoma and brain glioblastoma cells were analalyzed, with microarrays run both for control and treatment with dichloroacetate reveals a mitochondria-K+ channel axis is suppressed in cancer and its normalization promotes apoptosis inhibits cancer growth
The unique metabolic profile of most cancers (aerobic glycolysis) might confer apoptosis-resistance and be therapeutically targeted. Compared to normal cells, several human cancers have high mitochondrial membrane potential and low expression of the K+ channel Kv1.5, both contributing to apoptosis-r...

TranscriptomicsDemethyl fructiculin A (SCO-1) induces apoptosis by inducing reactive oxygen species in mitochondria
Demethyl fructiculin A is a diterpenoid quinone component of the exudates from Salvia corrugata (SCO-1) leafes. SCO-1 was recently reported to induce anoikis in mammalian cell lines via a molecular mechanism involving the presence of the membrane scavenging receptor CD36. However, experiments perfor...

ProteomicsMIRO-1 interacts with VDAC-1 to regulate mitochondrial membrane potential in Caenorhabditis elegans
Precise regulation of mitochondrial fusion and fission is essential for cellular activity and animal development. Imbalances between these processes can lead to fragmentation and loss of normal membrane potential in individual mitochondria. In this study, we show that MIRO-1 is stochastically elevat...

TranscriptomicsHeLa cell mitochondrial microRNAs
MicroRNAs (miRNAs) are small non-coding RNAs that associate with Argonaute 2 protein to regulate gene expression at the post-transcriptional level in the cytoplasm. However, recent studies have reported that some miRNAs localize to and function in other cellular compartments. Mitochondria harbour th...

TranscriptomicsOXPHOS deficiency activates global adaptation pathways to maintain mitochondrial membrane potential
Reduction of mitochondrial membrane potential is a hallmark of mitochondrial dysfunction. It activates adaptive responses in organisms from yeast to human to rewire metabolism, remove depolarized mitochondria, and degrade unimported precursor proteins. It remains unclear how cells maintain mitochond...
