Dagda et al. showed in this issue that cytosolic PINK1 released from the mitochondrion promotes dendritic outgrowth. This neurite-promoting activity of PINK1 is associated with the kinase activities of protein kinase A and is impaired by a pathogenic mutation in PINK1. The study by Dagda et al. has unravelled a novel mechanism underlying neurodegeneration caused by PINK1 mutation.

Research on the aetiology of neural tube defects (NTDs) has made progress in recent years. However, the molecular mechanism of apolipoproteins underlying NTDs development remains unclear. This study aimed to investigate the function of apolipoprotein M (ApoM) in the pathogenesis of NTDs and its underlying mechanisms.

The mitochondrial outer membrane (OMM) β-barrel proteins link the mitochondrion with the cytosol, endoplasmic reticulum, and other cellular membranes, establishing cellular homeostasis. Their active insertion and assembly in the outer mitochondrial membrane is achieved in an energy-independent yet highly effective manner by the Sorting and Assembly Machinery (SAM) of the OMM. The core SAM constituent is the 16-stranded transmembrane β-barrel Sam50.

Aims: Sterile inflammation is implicated in the development of heart failure (HF). Mitochondria plays important roles in triggering and maintaining inflammation. Mitophagy is important for regulation of mitochondrial quality and maintenance of cardiac function under pressure overload.

OMA1 is an ATP-independent zinc metalloprotease essential for maintaining mitochondrial homeostasis and plays a vital role in tumorigenesis. Depending on the type of cancer, a decrease in OMA1 expression has been linked to a varying prognosis for patients. The role of OMA1 in human osteosarcoma (OS), one of the most prevalent malignant bone tumors, remains elusive.

Introduction: Hyperglycemia is closely related to trophoblast dysfunction during pregnancy and results in suppressed invasion, migration, and pro-inflammatory cell death of trophoblasts. Hyperglycemia is a dependent risk factor for gestational hypertension accompanied by decreased placental growth factor (PLGF), which is important for maternal and fetal development. However, there is currently a lack of evidence to support whether PLGF can alleviate trophoblast cell dysfunction caused by high blood sugar.
