Inner membrane mitochondrial protein (Mic60) (Mic60)

Mic60, also known as Mitofilin or IMMT, is a fundamental structural protein of the inner mitochondrial membrane and the primary component of the Mitochondrial contact site and cristae organizing system (MICOS) (Source: UniProt Q16891). It plays a decisive role in maintaining mitochondrial cristae junctions and anchoring the inner membrane to the outer membrane, which is vital for metabolic homeostasis, protein trafficking, and mitochondrial DNA stability (Source: PubMed 22114354). In clinical research, Mic60 is recognized for its involvement in various pathologies; its deficiency leads to the collapse of mitochondrial architecture, a hallmark of neurodegenerative conditions like Parkinson's disease and certain cardiomyopathies (Source: PubMed 26830860). Conversely, in oncology, Mic60 mRNA is investigated as a therapeutic target where its knockdown via RNA interference can trigger mitochondrial stress and selective apoptosis in cancer cells by disrupting their metabolic adaptation (Source: PubMed 25781180). Research indicates that Mic60 levels are often suppressed in advanced cancers to facilitate metabolic reprogramming, yet its complete loss can be lethal to the cell (Source: PubMed 30104379). Targeting the Mic60 mRNA transcript allows for the modulation of these mitochondrial structures, potentially sensitizing tumors to other therapies. However, because Mic60 is vital for normal cellular respiration, therapeutic strategies must carefully address the risk of systemic mitochondrial toxicity (Source: PubMed 21944719). Current experimental approaches focus on localized delivery or tumor-specific promoters to mitigate these safety concerns.
