Targeted inhibition of mitochondrial oxidative phosphorylation (OXPHOS) complex generation is an emerging and promising cancer treatment strategy, but limited targets and specific inhibitors have been reported. Leucine-rich pentatricopeptide repeat-containing protein (LRPPRC) is an atypical RNA-binding protein that regulates the stability of all 13 mitochondrial DNA-encoded mRNA (mt-mRNA) and thus participates in the synthesis of the OXPHOS complex. LRPPRC is also a prospective therapeutic target for lung adenocarcinoma, serving as a promising target for OXPHOS inhibition.

Background: Autoimmune phenomena can be used in some patients with nonalcoholic fatty liver disease (NAFLD) in the clinic, but these patients are not autoimmune hepatitis patients.

Aim: To determine whether autoimmunity is present in patients with NAFLD, this study was performed.

Methods: A total of 104 patients with NAFLD diagnosed by liver biopsy at Tianjin Second People's Hospital between 2019 and 2023 were enrolled.

Hepatolenticular degeneration, also known as Wilson's disease, is a type of autosomal recessive genetic disorder of copper metabolism. The causative gene, ATP7B, is located on the long arm of chromosome 13 and encodes a P-type ATPase that is involved in copper transport. Pathogenic mutations in the ATP7B gene sequence lead to the diminished or lost function of the ATP7B protein, resulting in pathological copper deposition in organs such as the liver, brain, kidneys, and cornea.

Simple yet specific miRNA detection remains an enormous challenge due to its low abundance in samples and the high similarity among homologous miRNAs. Here, we propose a novel fluorescent approach for miRNA detection with greatly elevated accuracy by utilizing exonuclease-iii (Exo-iii) assisted twice target recognition. The proposed method involves a "Sensing probe" engineered with two loop sections to facilitate dual target miRNA recognition.
