Abstract

Background

Tumor-associated macrophages (TAM), a major component of the tumor microenvironment, play key roles in tumor formation and progression; however, mechanisms underlying TAM-induced tumor progression are complex and not well known. We previously reported that tumor cell-derived angiopoietin-like protein 2 (ANGPTL2) functions as a tumor promoter in some cancer contexts.

Methods

We examined ANGPTL2 expression in paraffin-embedded tumor samples from resected specimens of 221 patients with esophageal cancer. Patients were subdivided into four groups based on immunohistochemistry scores described above: ANGPTL2-low/TAM-low, ANGPTL2-low/TAM-high, ANGPTL2-high/TAM-low, and ANGPTL2-high/TAM-high groups. Gene expression datasets of esophageal cancer cell lines were obtained from the cancer cell line encyclopedia public database.

Results

In this study, we demonstrate that TAM infiltration is associated with poor prognosis in patients with esophageal cancer whose tumor cells show relatively higher ANGPTL2 expression levels; however, TAM infiltration did not affect prognosis in patients with ANGPTL2-low-expressing esophageal cancer, suggesting that ANGPTL2 expression in esophageal cancer cells is required for TAM-induced tumor progression. Our analysis of public datasets indicates a potential positive correlation of ANGPTL2 expression levels with that of transforming growth factor (TGF)-β, a TAM-activating factor, in esophageal cancer cell lines.

Conclusion

We conclude that ANGPTL2 signaling in tumor cells supports TAM-induced tumor progression and contributes to poor prognosis in patients with esophageal cancer. These findings overall provide novel insight into pro-tumor ANGPTL2 functions and illustrate the essential role of cancer cell/TAM crosstalk in cancer progression.

Neu im Fachgebiet Chirurgie

Welcher Zugangsweg ist besser für den interventionellen Mitralklappenersatz?

Bisher wird für den interventionellen Mitralklappenersatz standardmäßig der transapikale Zugangsweg gewählt. In einer Registeranalyse hat dieser in puncto Sicherheit allerdings den Kürzeren gezogen.

Lohnt sich die Karotis-Revaskularisation?

Die medikamentöse Therapie für Menschen mit Karotisstenosen hat sich in den vergangenen Dekaden verbessert. Braucht es also noch einen invasiven Eingriff zur Revaskularisation der Halsschlagader bei geringem bis moderatem Risiko für einen ipsilateralen Schlaganfall?

Höhere Dosis von Dexamethason senkt Überlebenschancen

Personen mit Hirnmetastasen, die perioperativ höhere kumulative Dosen von Dexamethason erhalten, haben eine schlechtere Prognose. Um die Ergebnisse zu verbessern, bedarf es strengerer Dosierungsschemata.

Appendektomie erhält Remission bei Colitis ulcerosa

Wird der Wurmfortsatz bei Personen mit Colitis ulcerosa entfernt, ist die Rückfallrate um ein Drittel geringer als unter konservativer Behandlung. Auch die Lebensqualität verbessert sich und der Bedarf an Medikamenten nimmt ab.
