“…Mitochondria play an important role in multiple processes, such as hyphal development, resistance to stress, virulence, apoptosis and sensitivity of yeast cells to drugs[ 31 – 33 ]. Cardiolipin and its precursor PG, the principal anionic phospholipid in mitochondrial membranes, are key elements in the response conferring resistance to osmotic and thermal stresses[ 34 , 35 ].…”

Candida albicans, one of the most common fungal pathogens, is responsible for several yeast infections in human hosts, being resistant to classically used antifungal drugs, such as azole drugs. Multifactorial and multistep alterations are involved in the azole resistance in Candida albicans. In this study, a FCZ-resistant C. albicans strain was obtained by serial cultures of a FCZ-susceptible C. albicans strain in incrementally increasing concentrations of FCZ. We performed an integrated profile of different classes of molecules related to azole resistance in C. albicans by combining several mass-spectrometry based methodologies. The comparative metabolomic study was performed with the sensitive and resistant strains of C.albicans to identify metabolites altered during the development of resistance to fluconazole, while the intervention strains and non-intervention strains of C.albicans to identify metabolites altered involved in cross-resistant to azole drugs. Our analysis of the different metabolites identified molecules mainly involved in metabolic processes such as amino acid metabolism, tricarboxylic acid cycle and phospholipid metabolism. We also compared the phospholipid composition of each group, revealing that the relative content of phospholipids significantly changed during the development of resistance to azole drugs. According with these results, we hypothesized that the metabolism shift might contribute to azole drugs resistance in C.albicans from multifactorial alterations. Our result paves the way to understand processes underlying the resistance to azole drugs in C. albicans, providing the basis for developing new antifungal drugs.

“…However, a mitochondrial response regulator (Srr1p) has been identified. 39,40 Srr1p appears to be unique to the Candida clade, with the exception of C. krusei 39 A knockout ssr1D is defective in hyphal development, adaptation to osmotic/oxidative stresses, and is avirulent. The participation of Srr1p in a signal pathway and its role in mitochondrial functions are unknown.…”

“…However, it is not clear whether acetylation of mitochondrial proteins takes place in the cytosol before their mitochondrial import or inside mitochondria? How the acetylation status influences mitochondrial function and nuclear cross-talk or even two-component signaling pathways that regulate fungal virulence [43] remains open. Notably, mitochondria and intrinsic signaling pathways play key roles in fungal pathogenesis [43, 44], but a link of acetylation, mitochondria, and virulence remains to be discovered.…”
