The last two decades we have witnessed an exciting development of metabolomics techniques and approaches. Without disregarding the other analytical tools, the two main analytical pillars are currently mass spectrometry (MS) and nuclear magnetic resonance spectroscopy (NMR). The total extracts of numerous plants, yeast, and human bio fluids were comprehensively characterised. With the equipment getting increasingly sensitive, we now see the first examples of cell and tissue metabolomes being, at least partially, resolved, with cancer cells and tissues being in the centre of attention.
Again the main challenges to be expected are: i) can we fully elucidate all detected metabolites, and ii) can we develop protocols for robust extraction and detection of the small metabolites? There are several interesting questions to be addressed: a) how can we learn from previous metabolomics studies, b) how can we organize the tremendous amount of data and metadata on metabolites in the most efficient way, and c) how can software tools help us solving the metabolomics challenges?
Herewith I invite you to contribute to this special issue of Metabolites: original research, a reviewing of the initial attempts, and ideas on how to tackle the cell and tissue metabolomics challenges in the nearby future are all welcome, from both the plant and human metabolomics field.

Abstract: Mitochondrial dysfunction(s) (MDs) can be defined as an alteration of the mitochondria including mitochondrial uncoupling, mitochondrial depolarization, inhibition of mitochondrial respiratory chain, mitochondrial network fragmentation, mitochondrial or nuclear DNA mutations and mitochondrial accumulation of protein aggregates. These MDs are known to be induced by several pathological states/diseases including cancer, obesity, muscular and neurological troubles. On the other hand, these conditions can also induce several mitochondrial dysfunctions by themselves. Induction of MDs can alter secretion of several metabolites (i.e. pro-inflammatory cytokines), reactive oxygen species (ROS) production and modify several cell signaling pathways (cytosolic calcium concentration, AMPK, PI3K, Akt, PKC, MEK pathways) in order to attempt to resolve the mitochondrial dysfunction or to ultimately trigger cell death. Along with ROS, many metabolites, such as fatty acids and derived compounds, could be also secreted into the blood stream by cells suffering from mitochondrial dysfunctions. In this review, we propose to summarize how some metabolites are able to induce or can be modified by a mitochondrial dysfunction, along with the signaling pathways and transcription factors involved in this process, with a strong emphasis on MU. For this purpose, we will summarize how it is possible to identify consequences or causes of a mitochondrial dysfunction by using complementary transcriptomics, proteomics (2D gels, liquid chromatography, gas chromatography) and metabolomics (liquid chromatography associated with mass spectrometry analysis, NMR spectrometry, PET scan, nanofluidic analysis of isolated mitochondria) approaches.
