Notes

METHODS: Twenty-eight biomarkers were analysed in 640 participants: 259 with SSc-ILD and 179 SSc-controls without ILD , 172 idiopathic pulmonary fibrosis -controls , and 30 healthy controls
A composite index was developed from biomarkers associated with ILD in multivariable analysis derived at empirical thresholds. Performance of the index to identify ILD, and specifically SSc-ILD, and its association with lung function, radiological extent, health-related quality of life were evaluated in derivation and validation cohorts. Biomarkers to distinguish SSc-ILD from IPF-controls were identified. RESULTS: A composite biomarker index, comprising SP-D, Ca15-3 and ICAM-1, was strongly associated with SSc-ILD diagnosis, independent of age, sex, smoking and lung function . The composite index strengthened the performance of individual biomarkers for SSc-ILD identification. In SSc patients, a higher index was associated with worse baseline disease severity and DLCO% , both p<001).

CONCLUSION: A composite serum biomarker index, comprising SP-D, Ca15-3 and ICAM-1 may improve the identification and risk-stratification of ILD in SSc patients at baseline.

Australian Idiopathic Pulmonary Fibrosis Registry, and associated investigators Recent efforts have focused on developing methylation risk scores , a weighted sum of the individual's DNA methylation values of pre-selected CpG sites. Buy Vitamin A of the current MRS approaches that utilize Epigenome-wide association studies summary statistics only include genome-wide significant CpG sites and do not consider co-methylation. New methods that relax the p-value threshold to include more CpG sites and account for the inter-correlation of DNAm might improve the predictive performance of MRS. We paired informed co-methylation pruning with P-value thresholding to generate pruning and thresholding MRS and evaluated its performance among multi-ancestry populations. Through simulation studies and real data analyses, we demonstrated that pruning provides an improvement over simple thresholding methods for prediction of phenotypes. We demonstrated that European-derived summary statistics can be used to develop P+T MRS among other populations such as African populations. However, the prediction accuracy of P+T MRS may differ across multi-ancestry population due to environmental/cultural/social metastasis by upregulating PD-L1 and CCL BACKGROUND & AIMS: Metastasis remains the major reason for high mortality of HCC patients.

This study was designed to investigate the role of E-twenty-six-specific sequence variant 4 in promoting HCC metastasis and explored new combination therapy strategy for ETV4-mediated HCC metastasis. METHODS: PLC/PRF/5, MHCC97H, Hepa1-6 and H22 cells were used to establishment of orthotopic HCC Models. Clodronate liposomes were used to clear macrophages in C57BL/6 mice. Gr-1 monoclonal antibody was used to clear myeloid derived suppressor cell in C57BL/6 mice. Flow cytometry and immunofluorescence were used to detect the changes of key immune cells in tumor microenvironment. RESULTS: ETV4 expression was positively related to higher TNM stage, poor tumor differentiation, microvascular invasion, and poor prognosis in human HCC. Overexpression of ETV4 in HCC cells transactivated programmed death ligand 1 and chemokine ligand 2 expression, which increased tumor-associated macrophages and myeloid derived suppressor cells infiltration and inhibited CD8 T cells accumulation.

Knockdown of CCL2 by lentivirus or CCR2 inhibitor CCX872 treatment impaired ETV4-induced TAMs and MDSCs infiltration and HCC metastasis. Furthermore, fibroblast growth factor 19 /fibroblast growth factor receptor 4 and hepatocyte growth factor /c-MET jointly upregulated ETV4 expression through ERK1/2 pathway. Additionally, ETV4 upregulated FGFR4 expression and downregulation of FGFR4 decreased ETV4-enhanced HCC metastasis, which created a FGF19-ETV4-FGFR4 positive feedback loop. Finally, anti-PD-L1 combined with FGFR4 inhibitor BLU-554 or MAPK inhibitor trametinib prominently inhibited FGF19-ETV4 signaling induced HCC metastasis. CONCLUSIONS: ETV4 is a prognostic biomarker, and anti-PD-L1 combined with FGFR4 inhibitor BLU-554 or MAPK inhibitor trametinib may be effective strategies to inhibit HCC metastasis.
