We and others have shown before that export of cytostatic drugs contributes to drug resistance. Now we provide a novel approach to overcome exosome-mediated drug resistance in aggressive B-cell lymphomas. Experimental Design: We used well-established centrifugation protocols to purify exosomes from DLBCL cell lines and detected anthracyclines using FACS and HPLC. We used shRNA knockdown of ABCA3 to determine ABCA3 dependence of chemotherapy susceptibility and monitored ABCA3 expression after indomethacin treatment using qPCR. Finally, we established an in vivo assay using a chorioallantoic membrane (CAM) assay to determine the synergy of anthracycline and indomethacin treatment. Results: We show increased efficacy of the anthracycline doxorubicin and the anthracenedione pixantrone by suppression of exosomal drug resistance with indomethacin. B-cell lymphoma cells in vitro efficiently extruded doxorubicin and pixantrone, in part compacted in exosomes. Exosomal biogenesis was critically dependent on the expression of the ATP-transporter A3 (ABCA3). Genetic or chemical depletion of ABCA3 augmented intracellular retention of both drugs and shifted the subcellular drug accumulation to prolonged nuclear retention. Indomethacin increased the cytostatic efficacy of both drugs against DLBCL cell lines in vitro and in vivo in a CAM assay. Conclusions: We propose pretreatment with indomethacin toward enhanced antitumor efficacy of anthracyclines and anthracenediones.

Exosomes, small membrane vesicles of endocytotic origin, have been implicated in intercellular communication processes such as the transfer of tumor cell antigens and the activation of recipient dendritic cells (DC). However, little is known about immunomodulatory functions of keratinocyte-derived exosomes. To address this question, we analysed exosome secretion of the murine keratinocyte cell line MPEK under steady state as well as inflammatory conditions (+/- IFN). These exosomes were readily taken up by bone marrow-derived DC (BMDC) in vitro resulting in a matured phenotype, as evidenced by increased CD40 expression as well as by the production of large amounts of IL-6, IL-10 and IL-12. When the transfer of antigen-specific information through exosomes was investigated, it was found that keratinocytes took up antigen (ovalbumin) and transferred it to their exosomes. However, these antigen-harbouring exosomes failed to induce antigen-specific T cell responses via BMDC. Together, this novel biological function suggests that keratinocytes are able to direct unspecific immune processes but do not elicit specific immune responses."],["dc.identifier.doi","10.1111/exd.12230"],["dc.identifier.isi","000325008600005"],["dc.identifier.pmid","24079734"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/28641"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","0906-6705"],["dc.title","Immunostimulatory activity of murine keratinocyte-derived exosomes"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The tumor typically develops in the atrophic, pachydermatous, hyperkeratotic skin of limbs affected by long-standing lymphedema. Clinical data associated with Stewart-Treves syndrome and lymphedema management have rarely been published. Methods and Results: In the period between 1980 and 2009, ten patients with Stewart-Treves syndrome were diagnosed and treated at the Foeldiklinik, Hinterzarten, Germany. Nine of the ten patients were female. Five patients had previously suffered from breast cancer (and were treated with mastectomy); two from other malignancies; two patients had primary lymphedema, and one had undergone lower extremity lymphadenectomy. All cancer patients had undergone radiation treatment. In all cases, the sarcoma developed in non-irradiated areas 6-48 years (average 16.3 years) after the onset of lymphedema. None of the patients had received complex decongestive physical therapy (CDT). Two patients had above-elbow amputation, one had shoulder exarticulation, two patients had wide excision and skin grafting, two patients had above-knee amputation procedure, two patients had a below-knee amputation procedure, and one patient had no surgical treatment at all. The time to recurrence after surgery, time to metastasis, patient survival and CDT were recorded. Conclusions: Patients with lymphedema should be closely examined starting 5 years from the time of lymphedema onset, paying special attention to those with associated malignancies. Only early diagnosis and treatment by radical ablative surgery confers a reasonable prognosis with this rare but aggressive disease. A potential effect of CDT on lymphangiosarcoma has to be studied in a greater patient cohort."],["dc.identifier.doi","10.1089/lrb.2015.0006"],["dc.identifier.isi","000372184300007"],["dc.identifier.pmid","26584023"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/41264"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Mary Ann Liebert, Inc"],["dc.relation.issn","1557-8585"],["dc.relation.issn","1539-6851"],["dc.title","Lymphangiosarcoma: Is Stewart-Treves Syndrome a Preventable Condition?"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]
