26375473 In interstitial lung disease, abnormal proSP-C was seen in small and dense lamellar bodies in type II alveolar epithelial cells. A549 cells expressing proSP-C(L55F) had abnormal organelles. It partly colocalized in CD63-positive cytoplasmic vesicles .
26041777 support a chaperone function of the BRICHOS domain, possibly together with the linker region, during pro-SP-C biosynthesis in the endoplasmic reticulum
25891900 cleavage of BRICHOS in a loop region that is cleaved during proSP-C biosynthesis results in increased capacity to delay Abeta(42) fibril formation.
25782673 We sequenced SFTPC and analyzed morphology, ultrastructure and SP expression in lung tissue when available. We identified eight subjects who were heterozygous for SP-C mutations.
25657025 analysis of clinical patterns in patients with SFTPC mutations
24099305 Structural modeling of transmembrane (BRICHOS) domains of SFTPC precursor and BRI2/ITM2B (integral membrane protein 2B) identifies conserved region structurally complementary to beta-sheet-/amyloid-prone regions in BRICHOS domain-containing proteins.
23406594 elevated expression in nasal mucosa in chronic rhinosinusitis with polyps
22458263 The A116D mutation leads to impaired processing of proSP-C in alveolar epithelial cells, alters cell viability and lipid composition, and also activates cells of the immune system.
21828032 Mutation increases endoplasmic reticulum stress and induces apoptotic cell death compared with wild-type SP-C in alveolar type II cells, supporting the significance of this mutation in the pathogenesis of pulmonary fibrosis.
21707890 Data show that, in contrast to its wild-type counterpart, SP-C(I73T) is misdirected to the plasma membrane and subsequently internalized to the endocytic pathway via early endosomes, leading to the accumulation of abnormally processed proSP-C isoforms.
