Abstract:
In order to maintain a functional mitochondrial network, cells have developed a quality control mechanism, namely mitophagy. This process can be induced through different pathways. The most studied is the so-called PINK1/Parkin pathway, which is associated with ubiquitylation of several mitochondrial proteins that were initially found to be related to Parkinson's disease. Another type of mitophagy is known as receptor-mediated mitophagy, which includes proteins, such as BNIP3 and BNIP3L, also known as Nix. Through these two mechanisms, mitophagy fulfills its functions and maintains cellular homeostasis. Here, we summarize the current knowledge about the mechanisms of mitophagy regulation and their interplay with cancer progression as well as anticancer treatment.

- Molecular Biology
- Oncology
Background:
- Cells utilize mitophagy for mitochondrial quality control to maintain a functional mitochondrial network.
- Mitophagy is essential for cellular homeostasis and can be triggered via distinct pathways.
- Dysregulation of mitophagy is increasingly implicated in various disease states, including cancer.
Purpose of the Study:
- To summarize current knowledge on mitophagy regulation mechanisms.
- To elucidate the interplay between mitophagy and cancer progression.
- To review the role of mitophagy in anticancer treatment efficacy.
Main Methods:
- Literature review of mitophagy pathways, including PINK1/Parkin and receptor-mediated mitophagy (BNIP3, Nix).
- Analysis of studies investigating mitophagy's role in cancer development and progression.
- Examination of research on mitophagy modulation in cancer therapy.
Main Results:
- The PINK1/Parkin pathway involves ubiquitylation of mitochondrial proteins linked to Parkinson's disease.
