Serum amyloid A: A potential biomarker of lung disorders

Publication date: Available online 8 November 2019Source: Respiratory InvestigationAuthor(s): Lucia Vietri, Annalisa Fui, Laura Bergantini, Miriana d’Alessandro, Paolo Cameli, Piersante Sestini, Paola Rottoli, Elena BargagliAbstractSerum amyloid A is an acute-phase protein with multiple immunological functions. Serum amyloid A is involved in lipid metabolism, inflammatory reactions, granuloma formation, and cancerogenesis. Additionally, serum amyloid A is involved in the pathogenesis of different autoimmune lung diseases. The levels of serum amyloid A has been evaluated in biological fluids of patients with different lung diseases, including autoimmune disorders, chronic obstructive pulmonary diseases, obstructive sleep apnea syndrome, sarcoidosis, asthma, lung cancer, and other lung disorders, such as idiopathic pulmonary fibrosis, tuberculosis, radiation pneumonitis, and cystic fibrosis. This review focuses on the cellular and molecular interactions of serum amyloid A in different lung diseases and suggests this acute-phase protein as a prognostic marker.

A mutation found in esophageal cancer alters integrin β4 mRNA splicing. Biochem Biophys Res Commun. 2020 Aug 27;529(3):726-732 Authors: Kelly GT, Faraj R, Dai Z, Cress AE, Wang T Abstract Integrin β4 (CD104, mRNA: ITGβ4) contributes to anchoring cells to the extracellular matrix and is regulated in many cancer types where it contributes to tumor progression. One splice variant, integrin β4E, is poorly characterized. We extracted several mutations from tumor samples within ITGB4 near the splice site that controls ITGβ4E production, and computational analysis predicted six of th...

This study aimed to investigate the stability and therapeutic efficacy of the modified LNA- and PNA-type anti-miRs in a murine prostate cancer model under various treatment conditions. After verifying the anti-cancer potential of anti-miR21 by targeting tumor suppressor PTEN, the potential of the modified LNA- and PNA-type anti-miR21s was compared in vitro and in vivo. We found that PNA-type anti-miR21 showed better stability and therapeutic efficacy in the xenografted mouse tumor model than the LNA-type anti-miR21. Furthermore, PNA-type anti-miR21 treatment showed reduced tumor metastasis. This study may serve a...

In conclusion, five different imatinib-resistant GIST cell lines including the EXOC2-AK7 fusion gene derived from GIST-R5 represent important research tools for the investigation of cancer cell mechanisms underlying drug resistance and genetic variation. Furthermore, our study may facilitate pre-clinical studies of new therapeutic strategies. PMID: 32736695 [PubMed - as supplied by publisher]

Abstract The anticancer antibiotic heptelidic acid is a sesquiterpene lactone produced by the beneficial plant fungus Trichoderma virens. This species has been separated into two strains, referred to as P and Q, based on its biosynthesis of secondary metabolites; notably, only P-strains were reported to produce heptelidic acid. While characterizing a Q-strain of T. virens containing a directed mutation in the non-ribosomal peptide synthetase encoding gene Tex7, the appearance of an unknown compound in anomalously large quantities was visualized by TLC. Using a combination of HPLC, LC-MS/MS, and NMR spectrosco...

The objective of the study is to determine the patterns of regulation of single-walled carbon nanotube accumulation, distribution, and agglomeration in glioma cells exposed to an external electric field. C6 glioma cells were treated with 5 μg/ml DNA wrapped single-walled carbon nanotubes and exposed to bi-phasic electric pulses (6.6 V/m, 200 Hz, pulse duration 1 ms). Nanotube accumulation was determined by Raman microspectroscopy and their intracellular local concentration was evaluated using the G-band intensity in Raman spectra of single-walled carbon nanotubes. It was revealed that the low-frequen...

In conclusion, the deletion of Prx I triggered the DMBA/TPA-induced skin tumor formation in vivo and in vitro by regulating the reactive oxygen species (ROS)-p38 mitogen-activated protein kinase (MAPK) pathway. These findings provide a theoretical basis for treating skin cancer. PMID: 32736685 [PubMed - as supplied by publisher]

In this study, we initially investigated the distribution of Scai mRNA in the developing rat brain and in neurons. We found that, although Scai mRNA levels decreased during brain development, it was highly expressed in several brain regions and in neurons but not astrocytes. Subsequently, in addition to Scai variant 1, we identified novel rat Scai variants 2 and 3 and characterized their functions in Neuro-2a cells. The novel Scai variants 2 and 3 contain unique exons that possess stop codons and therefore encode shorter proteins compared with the full-length Scai variant 1. SCAI variants 2 and 3 possess a nuclear localiza...
