Kinetics of Squalene Quenching Singlet Oxygen and the Thermal Degradation Products Identification.

Squalene has been proven to possess various bioactive functions that are widely present in vegetable oils. A more comprehensive understanding of the reaction behavior of squalene under oxidative conditions was achieved by studying its antioxidant capacity and thermal degradation products. The total singlet oxygen quenching rate constant ( ) of squalene was 3.

PKD1 deficiency induces Bronchiectasis in a porcine ADPKD model.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is a prevalent genetic disorder, mainly characterized by the development of renal cysts, as well as various extrarenal manifestations. Previous studies have shown that ADPKD is related to bronchiectasis, while its pathogenic mechanism is unclear. In previous studies, we have generated the PKD1 pigs to simulate the progression of cyst formation and physiological alterations similar to those seen in ADPKD patients.

Activation of PI3K/p110α in the Lung Mesenchyme Affects Branching Morphogenesis and Club Cell Differentiation.

Epithelial-mesenchymal interaction is required for normal growth, morphogenetic patterning, and cellular differentiation in developing lungs. Various signaling pathways have been defined in establishing the patterning of this branched organ. The phosphoinositide-3-kinase (PI3K) signaling plays an important role in disease pathogenesis but remains largely uncharacterized in embryonic development.

TMEM116 is required for lung cancer cell motility and metastasis through PDK1 signaling pathway.

Transmembrane protein (TMEM) is a family of protein that spans cytoplasmic membranes and allows cell-cell and cell-environment communication. Dysregulation of TMEMs has been observed in multiple cancers. However, little is known about TMEM116 in cancer development.

The effects of intrinsic apoptosis on cystogenesis in PKD1-deficient ADPKD pig model.

Background: Apoptosis is a form of cell death that plays a critical role in the maintenance of tissue homeostasis involving the development and elimination of unwanted cells. Dysregulation of apoptosis appears to be associated in the pathogenesis of many human diseases. Autosomal dominant polycystic kidney disease (ADPKD) is a common monogenetic disease and is mainly caused by mutations in PKD1.

The role of pulmonary mesenchymal cells in airway epithelium regeneration during injury repair.

Background: The airways of mammalian lung are lined with highly specialized cell types that are the target of airborne toxicants and injury. Several epithelial cell types and bone marrow-derived mesenchymal stem cells have been identified to serve as stem cells during injury repair. However, the contributions of endogenous mesenchymal cells to recruitment, expansion or differentiation of stem cells, and repair and reestablishment of the normal composition of airway epithelium following injury have not been addressed.
