Abstract
Tumor-derived total RNA (TdRNA) and cell lysate (TCL), with almost all the relevant tumor antigens, represent attractive alternative sources of antigens in antitumor immunotherapy. However, the comparison of their capacity to elicit immune responses against breast cancer is still lacking. In this study, the antitumor immune effects of TdRNA and TCL were systematically compared. We isolated TdRNA and TCL from 4T1 mouse breast cancer cells, and found that both sources of antigens could stimulate the maturation of dendritic cells (DCs) at the cellular and in vivo levels, and induce robust cellular immune responses, as evidenced by the increased percentages of both CD4+ and CD8+ T cells in the inguinal lymph nodes and spleen. But TdRNA performed stronger immunoactivities than TCL on the increase of T cell population through DCs activation. Additionally, the synergistic antitumor efficacy of paclitaxel (PTX) with TdRNA and TCL respectively was further evaluated in the murine 4T1 tumor model. Compared with TCL, TdRNA could inhibit tumor growth more effectively with low systemic toxicity when combined with PTX, which was, at least in part, attributable to the improvement of systemic immune function and tumor immune infiltration. Overall, TdRNA outperforms TCL in antitumor immunity, and is expected to be a promising candidate for application as the source of tumor antigens.

Oncol Lett 2015; 10:3471-3477. [PMID: 26788152 PMCID: PMC4665379 DOI: 10.3892/ol.2015.3752] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2014] [Accepted: 08/17/2015] [Indexed: 12/31/2022] Open
Abstract
Endothelial-like differentiation (ELD) of dendritic cells (DCs) is a poorly understood phenomenon. The present study evaluated the effect on the ELD of DCs by using human esophageal squamous cell carcinoma (ESCC) cells with high or poor differentiation. The results demonstrated that KYSE450 (highly differentiated) and KYSE70 (poorly differentiated) cell supernatants induce the differentiation of immature DCs (iDCs), derived from healthy adult volunteers, away from the DC pathway and towards an endothelial cell (EC) fate. This effect was strongest in the cells treated with the KYSE70 supernatant. During the ELD of iDCs, sustained activation of JAK (janus tyrosine kinase)/STAT3 (signal transducer and activator of transcription 3) signaling was detected. Incubation of iDCs with the JAK inhibitor, AG490 blocked JAK/STAT3 phosphorylation and iDC differentiation. These results suggested that the JAK/STAT3 signaling pathway mediates ELD of iDCs. Furthermore, the poorly differentiated ESCC cells may have a greater effect on the ELD of iDCs than highly differentiated ESCC cells.
