Anti-C1QC polyclonal antibody

Purpose: To investigate the expression of complement factors in pterygium tissues compared to normal conjunctival samples, using next-generation RNA sequencing Methods: Twenty pterygium and 20 healthy conjunctival samples were obtained from 19 patients who consented to pterygium excision and conjunctival autograft surgery. Tissues (pterygium and normal conjunctiva) were analyzed using next-generation RNA sequencing. Significant gene lists were obtained using DAVID, GSEA, and KEGG for enriched pathway analyses of differentially expressed genes. Real-time polymerase chain reaction was performed to validate differential expressions of complement factors. Results: There was 3.15 +/- 2.6, 3.21 +/- 4.6, 3.03 +/- 1.83, 4.28 +/- 6.12, and 4.96 +/- 1.89-fold increase in the expression of CFH, C2, C1QB, C1QC, and MASP1, respectively, in pterygium samples compared to normal conjunctival samples. Pterygium size correlated well with the expression of CFH, C1QB, C1QC and MASP1. Conclusion: Alternative and lectin complement systems are activated in pterygia samples compared to normal conjunctival samples.

Esophageal squamous cell carcinoma (ESCC) is a common malignancy with poor prognosis and survival rate. To identify meaningful long non-coding RNA (lncRNA), microRNA (miRNA), and messenger RNA (mRNA) modules related to the ESCC prognosis, The Cancer Genome Atlas-ESCC was downloaded and processed, and then, a weighted gene co-expression network analysis was applied to construct lncRNA co-expression networks, miRNA co-expression networks, and mRNA co-expression networks. Twenty-one hub lncRNAs, seven hub miRNAs, and eight hub mRNAs were clarified. Additionally, a competitive endogenous RNAs network was constructed, and the emerging role of the network involved in head and neck squamous cell carcinoma (HNSCC) was also analyzed using several webtools. The expression levels of eight hub genes (TBC1D2, ATP6V0E1, SPI1, RNASE6, C1QB, C1QC, CSF1R, and C1QA) were different between normal esophageal tissues and HNSCC tissues. The expression levels of TBC1D2 and ATP6V0E1 were related to the survival time of HNSCC. The competitive endogenous RNAs network might provide common mechanisms involving in ESCC and HNSCC. More importantly, useful clues were provided for clinical treatments of both diseases based on novel molecular advances.
