The Biological Role of LRPPRC in Human Cancers.

The leucine-rich pentatricopeptide repeat-containing (LRPPRC) protein, a member of the pentatricopeptide repeat (PPR) family, is a mitochondria-associated protein that regulates various biological processes, including cell cycle progression and mitochondrial gene translation. LRPPRC has also been identified as an important causative gene in several mitochondrial diseases. N6-methyladenosine (m6A) is the most prevalent and extensive modification of mRNA in eukaryotes, playing a significant role in cellular proliferation, differentiation, and oncogenesis. As an m6A regulator, LRPPRC has been shown to play an important role in the development of various human metabolic diseases and malignant tumors. This review mainly focuses on summarizing the biological roles of LRPPRC in a variety of human malignant tumors, emphasizing the molecular mechanisms LRPPRC is involved in and its potential impact on tumor prognosis.
