Abstract
Natural killer (NK) cells lyse invading tumor cells to limit metastatic growth in the lung, but how some cancers evade this host protective mechanism to establish a growing lesion is unknown. Here, we have combined ultra-sensitive bioluminescence imaging with intravital two-photon microscopy involving genetically encoded biosensors to examine this question. NK cells eliminated disseminated tumor cells from the lung within 24 hr of arrival, but not thereafter. Intravital dynamic imaging revealed that 50% of NK-tumor cell encounters lead to tumor cell death in the first 4 hr after tumor cell arrival, but after 24 hr of arrival, nearly 100% of the interactions result in the survival of the tumor cell. During this 24-hr period, the probability of ERK activation in NK cells upon encountering the tumor cells was decreased from 68% to 8%, which correlated with the loss of the activating ligand CD155/PVR/Necl5 from the tumor cell surface. Thus, by quantitatively visualizing, the NK-tumor cell interaction at the early stage of metastasis, we have revealed the crucial parameters of NK cell immune surveillance in the lung.

Intravital Imaging Identifies the VEGF-TXA 2 Axis as a Critical Promoter of PGE 2 Secretion from Tumor Cells and Immune Evasion. Cancer Res 2021; 81:4124-4132. [PMID: 34035084 DOI: 10.1158/0008-5472.can-20-4245] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2020] [Revised: 04/14/2021] [Accepted: 05/11/2021] [Indexed: 11/16/2022]
Abstract
Prostaglandin E2 (PGE2) promotes tumor progression through evasion of antitumor immunity. In stark contrast to cyclooxygenase-dependent production of PGE2, little is known whether PGE2 secretion is regulated within tumor tissues. Here, we show that VEGF-dependent release of thromboxane A2 (TXA2) triggers Ca2+ transients in tumor cells, culminating in PGE2 secretion and subsequent immune evasion in the early stages of tumorigenesis. Ca2+ transients caused cPLA2 activation and triggered the arachidonic acid cascade. Ca2+ transients were monitored as the surrogate marker of PGE2 secretion. Intravital imaging of BrafV600E mouse melanoma cells revealed that the proportion of cells exhibiting Ca2+ transients is markedly higher in vivo than in vitro. The TXA2 receptor was indispensable for the Ca2+ transients in vivo, high intratumoral PGE2 concentration, and evasion of antitumor immunity. Notably, treatment with a VEGF receptor antagonist and an anti-VEGF antibody rapidly suppressed Ca2+ transients and reduced TXA2 and PGE2 concentrations in tumor tissues. These results identify the VEGF-TXA2 axis as a critical promoter of PGE2-dependent tumor immune evasion, providing a molecular basis underlying the immunomodulatory effect of anti-VEGF therapies. SIGNIFICANCE: This study identifies the VEGF-TXA2 axis as a potentially targetable regulator of PGE2 secretion, which provides novel strategies for prevention and treatment of multiple types of malignancies.
