EZH2 elicits CD8 T-cell desert in esophageal squamous cell carcinoma via suppressing CXCL9 and dendritic cells.

CD8 T cell spatial distribution in the context of tumor microenvironment (TME) dictates the immunophenotypes of tumors, comprised of immune-infiltrated, immune-excluded and immune-desert, discriminating "hot" from "cold" tumors. The infiltration of cytotoxic CD8 T cells is associated with favorable therapeutic response. Hitherto, the immunophenotypes of esophageal squamous cell carcinoma (ESCC) have not yet been comprehensively delineated.

circular RNA circ-231 promotes protein biogenesis of TPI1 and PRDX6 through mediating the interaction of eIF4A3 with STAU1 to facilitate unwinding of secondary structure in 5' UTR, enhancing progression of human esophageal squamous cell carcinoma (ESCC).

The nuclear cap-binding complex (CBC)-dependent translation (CT) is an important initial translation pathway for 5'-cap-dependent translation in normal mammal cells. Eukaryotic translation initiation factor 4A-III (eIF4A3), as an RNA helicase, is recruited to CT complex and enhances CT efficiency through participating in unwinding of secondary structure in the 5' UTR. However, the detailed mechanism for eIF4A3 implicated in unwinding of secondary structure in the 5' UTR in normal mammal cells is still unclear.

linc01305 promotes metastasis and proliferation of esophageal squamous cell carcinoma through interacting with IGF2BP2 and IGF2BP3 to stabilize HTR3A mRNA.

Evidence shows that long noncoding RNAs (lncRNAs) modulate mRNAs of multiple genes by post-transcriptional regulation. However, in esophageal squamous cell carcinoma, lncRNAs involvement in post-transcriptional regulation of mRNAs have been rarely reported. In this study, we investigated a novel mechanism of linc01305 promoting metastasis and proliferation of ESCC.
