Drug resistance represents a major obstacle in cancer management, and the mechanisms underlying stress adaptation of cells response to therapy-induced hostile environment are largely unknown. As central organelle for cellular energy supply, mitochondria can rapidly undergo dynamic changes integrate signaling pathways provide bioenergetic biosynthetic flexibility cells, which contributes multiple aspects tumor characteristics, including drug resistance. Therefore, targeting therapy overcoming has attracted increasing attention various types cancer. Multiple mitochondrial processes, dynamics, metabolism, apoptotic regulatory machinery, have been demonstrated be potential targets. However, recent insights into revealed complexity structure functions, elusive functions biology, inaccessibility mitochondria, posed challenges clinical application mitochondrial-based therapeutic strategies. discovery both novel mitochondria-targeting agents innovative approaches is urgently required. Here, we review most literature summarize molecular their intricate connection with In addition, an overview emerging strategies target effectively chemoresistance highlighted, emphasis on repositioning delivery approaches, may accelerate compounds therapy.

Mitochondria play a key role in both health and disease. Their function is not limited to energy production but serves multiple mechanisms varying from iron calcium homeostasis the of hormones neurotransmitters, such as melatonin. They enable influence communication at all physical levels through interaction with other organelles, nucleus, outside environment. The literature suggests crosstalk between mitochondria circadian clocks, gut microbiota, immune system. might even be hub supporting integrating activity across these domains. Hence, they (missing) link Mitochondrial dysfunction related metabolic syndrome, neuronal diseases, cancer, cardiovascular infectious inflammatory disorders. In this regard, diseases Alzheimer’s, Parkinson’s, amyotrophic lateral sclerosis (ALS), chronic fatigue syndrome (CFS), pain are discussed. This review focuses on understanding mitochondrial action that allow for maintenance pathways toward dysregulated mechanisms. Although have allowed us adapt changes over course evolution, turn, evolution has shaped mitochondria. Each evolution-based intervention influences its own way. use physiological stress triggers tolerance stressor, achieving adaptability resistance. describes strategies could recover functioning providing comprehensive, root-cause-focused, integrative approach recovering treating people suffering diseases.

Calcium Overload and Mitochondrial Metabolism

Biomolecules, Journal Year: 2022, Volume and Issue: 12(12), P. 1891 - 1891

Published: Dec. 17, 2022

Mitochondria calcium is a double-edged sword. While low levels of are essential to maintain optimal rates ATP production, extreme overcoming the mitochondrial retention capacity leads loss function. In moderate amounts, however, synthesis inhibited in calcium-titratable manner. consequences overload well-known, effects on function moderately loaded range remain enigmatic. These observations associated with changes mitochondria ultrastructure and cristae network. The present mini review/perspective follows up previous studies using well-established cryo–electron microscopy poses an explanation for observable depressed during calcium-overloaded states. results presented herein suggest that inhibition oxidative phosphorylation not caused by direct decoupling energy metabolism via opening calcium-sensitive, proteinaceous pore but rather separate related calcium-dependent phenomenon. Such states points towards ultrastructural modifications, enzyme activity changes, or interplay between both events.
