Summary: Mitophagy is an essential cellular process that regulates mitochondrial quantity through autophagy, with BNIP3L/Nix serving as a receptor. BNIP3L is involved in various physiological and pathological processes and is crucial in the induction of mitophagy. This review provides an overview of BNIP3L-mediated mitophagy, its molecular regulation, and its potential role in human diseases such as cancer and neurological disorders.

Summary: The study found that nanoplastics can be internalized by cells and disrupt mitochondrial functionality, leading to aberrations in energy metabolism. Accumulation of nanoplastics in alimentary sources poses a significant hazard to the mammalian gastrointestinal system. The study also revealed that high concentrations of nanoplastics hinder the process of mitophagy, leading to pathological consequences and influencing gut microbiota composition and nutritional metabolism.

Summary: This study found that cadmium induces mitochondrial mass decrease by activating PINK1-Parkin and Nix pathways. Puerarin improved the decrease in mitochondrial membrane potential induced by Cd, and blocked mitophagy mediated by PINK1-Parkin and Nix, inhibiting Cd-induced mitochondrial mass decrease in rat cortical neurons both in vitro and in vivo.

Summary: This study investigated the effect of baicalin on mitophagy in the hippocampus of mice exposed to chronic unpredictable mild stress (CUMS) and explored its potential mechanism. The results showed that baicalin improved depressive-like behaviors in CUMS mice and ameliorated mitochondrial structural impairment in the hippocampus neuron. Baicalin increased NIX and AMPK, and improved mitophagy level and mitochondrial function in HT22 cells by directly binding to AMPK.

Summary: Mitophagy is a specialized form of autophagy that selectively removes mitochondria. BNIP3L/NIX, a well-studied mitophagy receptor, plays a crucial role in the programmed removal of healthy mitochondria across various cell types, but questions remain regarding its regulation and balancing between cellular life and death decisions.

Summary: Our study reveals that the mitochondrial translation elongation factor Tu located on the outer membrane of mitochondria can inhibit altered mitochondria-induced apoptosis through its autophagic function. The autophagy-competent TUFM is required for self-dimerization and mitophagy, and its stabilization upon autophagy activation could inhibit caspase-8 activation, providing insights into the regulation of apoptosis by mitophagy.

Summary: In this study, PD was found to inhibit the growth of human OS cells by upregulating apoptotic-related proteins and mitophagy-related proteins. The inhibition of LC3 or NIX decreased apoptosis and mitophagy in PD-treated cells. Knockdown of p38MAPK decreased mitochondrial dysfunction, autophagy, mitophagy, and NIX/LC3B expression in PD-treated cells. Binding affinity analysis revealed a strong binding affinity in the PD-NIX and PD-LC3 complexes. These findings suggest that PD-induced mitophagy inhibition may represent a novel therapeutic strategy for human OS by targeting the NIX/LC3 pathways.

Summary: This review summarizes the methods for identifying super-enhancers and core regulatory circuits in cancer cells, as well as the mechanisms by which master transcription factors and super-enhancers cooperatively regulate cancer-specific expression programs. It also discusses the cancer type and subtype specificity of core regulatory circuits and their significance in cancer biology.

Summary: Members of the IRF gene family, including IRF1, IRF2, IRF5, IRF8, and IRF9, are significantly upregulated in glioma and associated with advanced tumor grades and poorer outcomes. Low mutation rates but genetic alterations in IRFs are linked to more favorable patient survival. Functional analysis reveals IRFs involvement in glioma pathology mainly through inflammation- and immunity-related pathways, with correlations identified between IRFs and immune cell infiltration in glioma tissues. These findings suggest that IRF family members may serve as prognostic biomarkers and indicators of immune status in glioma patients.

Summary: Recent studies suggest that mitophagy, a selective autophagy process that removes damaged mitochondria, may be involved in various neurological disorders. This study found that the inflammation cytokine TNF-alpha impaired mitophagy in the prefrontal cortex, leading to the accumulation of damaged mitochondria and resulting in synaptic defects and behavioral abnormalities. The downregulation of the mitophagy protein NIX was observed in both patients with major depressive disorder and animal models, and restoring NIX levels alleviated behavioral abnormalities.

Summary: Analysis of RNASeq data from PBMCs of treatment naive TB patients and healthy controls showed dysregulation of metabolic pathways and upregulation of mitophagy due to M. tuberculosis (Mtb) infection. Transcriptomic data from NCBI-GEO database indicated that M. bovis (BCG) infection also induces similar metabolic rewiring and mitophagy pathways. Chronic Mtb infection and BCG in-vitro infection downregulated oxidative phosphorylation while upregulating glycolysis and mitophagy, suggesting non-pathogenic mycobacterial species BCG can be used as a model for studying Mtb infection outcomes.

Summary: Jionoside A1, a substance found in Rehmannia glutinosa, may have protective effects against ischemic stroke by reducing the consequences of ischemia-reperfusion injury and promoting neurological recovery. These findings provide theoretical justification for the application of Jionoside A1 in the treatment of ischemic stroke.

Summary: Selective autophagy is a key mechanism for the degradation of specific subcellular organelles and materials, as well as a defense mechanism against invading pathogens such as viruses. However, viruses have evolved strategies to counteract host antiviral defenses and manipulate selective autophagy for their successful infection. This review focuses on the regulation of selective autophagy by human herpesviruses.

Summary: Recently, it has been discovered that viruses can regulate selective autophagy to facilitate productive infections. Specifically, the human herpesvirus 8 (HHV-8) activates selective autophagy of mitochondria, called mitophagy, to inhibit antiviral immune responses during lytic infection in host cells. The viral interferon regulatory factor 1 (vIRF-1) of HHV-8 plays a crucial role in mitophagy activation by directly binding to mammalian autophagy-related gene 8 (ATG8) proteins, particularly GABARAPL1. The mitophagy receptor NIX promotes the interaction between vIRF-1 and GABARAPL1, and this interaction is essential for mitophagy activation and productive replication of HHV-8.
