To identify further cancer risk-modifying loci, we performed a multi-stage GWAS of 11,705 BRCA1 carriers (of whom 5,920 were diagnosed with breast and 1,839 were diagnosed with ovarian cancer), with a further replication in an additional sample of 2,646 BRCA1 carriers. We identified a novel breast cancer risk modifier locus at 1q32 for BRCA1 carriers (rs2290854, P = 2.7 x 10(-8), HR = 1.14, 95\% CI: 1.09-1.20). In addition, we identified two novel ovarian cancer risk modifier loci: 17q21.31 (rs17631303, P = 1.4 x 10(-8), HR = 1.27, 95\% CI: 1.17-1.38) and 4q32.3 (rs4691139, P = 3.4 x 10(-8), HR = 1.20, 95\% CI: 1.17-1.38). The 4q32.3 locus was not associated with ovarian cancer risk in the general population or BRCA2 carriers, suggesting a BRCA1-specific association. The 17q21.31 locus was also associated with ovarian cancer risk in 8,211 BRCA2 carriers (P = 2 x 10(-4)). These loci may lead to an improved understanding of the etiology of breast and ovarian tumors in BRCA1 carriers. Based on the joint distribution of the known BRCA1 breast cancer risk-modifying loci, we estimated that the breast cancer lifetime risks for the 5\% of BRCA1 carriers at lowest risk are 28\%-50\% compared to 81\%-100\% for the 5\% at highest risk. Similarly, based on the known ovarian cancer risk-modifying loci, the 5\% of BRCA1 carriers at lowest risk have an estimated lifetime risk of developing ovarian cancer of 28\% or lower, whereas the 5\% at highest risk will have a risk of 63\% or higher. Such differences in risk may have important implications for risk prediction and clinical management for BRCA1 carriers.}, language = {en} } @phdthesis{Blank2009, author = {Blank, Marc}, title = {Mechanismen der Glukokortikoid-induzierten Apoptose in T-Zellen}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-41332}, school = {Universit{\"a}t W{\"u}rzburg}, year = {2009}, abstract = {Glukokortikoide induzieren Apoptose in vielen verschiedenen Zelltypen. Wenngleich die Glukokortikoid-induzierte Apoptose eine der zuerst entdeckten Formen des Programmierten Zelltodes war, ist sie dennoch kaum verstanden und daher heute noch Teil vieler Forschungen. Eine Bcl-2 {\"U}berexpression resultiert in einer Resistenz gegen{\"u}ber GC- induzierter Apoptose in einer Reihe von Zellen wie einigen Lymphomzell-linien, aber auch normalen Thymozyten, sowie reifen T- und B-Zellen. Glukokortikoide k{\"o}nnen die Transkription der BH3-only Gene Bim (BCL-2-interacting mediator of cell death) und Puma (p53-upregulated modulator of apoptosis), einer proapoptotischen Untergruppe der Bcl-2 Familie, induzieren. Dies legt nahe, dass Bim und Puma am Weg der GC-induzierten Apoptose beteiligt sind. Ceramid ist in der Lage {\"u}ber die Aktivierung der proapoptotischen Bcl-2 Mitglieder Bax und Bak die {\"a}ußere Mitochondrienmembran zu sch{\"a}digen und damit zur Aktivierung von Caspasen zu f{\"u}hren. Verschiedene apoptotische Stimuli, wie z.B. Glukokortikoide, f{\"u}hren so {\"u}ber eine Erh{\"o}hung des endogenen Ceramid Levels zur Apoptose. Ceramid kann auf zwei verschiedenen Wegen gebildet werden: zum einen durch Hydrolyse von Sphingomyelin (katalysiert durch saure (a), oder neutrale (n) Sphingomyelinase (SMase)), zum anderen durch de novo Biosynthese. Studien an Thymozyten zeigen, dass von den beiden M{\"o}glichkeiten der Ceramidsynthese, lediglich die Inhibition der aSMase zu einer Resistenz gegen{\"u}ber GC-induzierter Apoptose f{\"u}hrt. Um nun die Rolle von Bim und der aSMase bei der Glukokortikoid-induzierten Apoptose zu untersuchen, wurde die murine T-Zelllymphomlinie WEHI7.15a zu Hilfe genommen. W{\"a}hrend die {\"U}berexpression retroviral eingebrachter shRNAs gegen Bim und aSMase keine Wirkung auf die Glukokortikoid-induzierte Apoptose zeigten, f{\"u}hrte der knockdown des Glukokortikoid-Rezeptors selbst zu einer Resistenz gegen{\"u}ber Dexamethason. Auch der pharmakologische Inhibitor der Sphingomyelin-Hydrolyse, Imipramin, zeigte sowohl in vitro, als auch in vivo keine Wirkung auf die Glukokortikoid-induzierte Apoptose. Dar{\"u}ber hinaus waren sowohl Thymozyten, als auch periphere T-Zellen von aSMase knockout M{\"a}usen genauso sensitiv auf die Glukokortikoid-induzierte Apoptose wie Wildtyp-Zellen. Die in vitro knockdown Ergebnisse von Bim und vom Glukokortikoid-Rezeptor selbst, konnten weiterhin ex vivo, durch das Einbringen der shRNAs in h{\"a}matopoetische Stammzellen, welche zur Rekonstitution bestrahlter M{\"a}use genutzt wurden, best{\"a}tigt werden. W{\"a}hrend der Bim knockdown keinerlei Einfluss auf die Glukokortikoid-induzierte Apoptose ex vivo zeigte, konnte die verminderte Expression des Glukokortikoid-Rezeptors den Zelltod verhindern. Im Gegensatz hierzu zeigten sowohl der GR knockdown, als auch der Bim knockdown im h{\"a}matopoetischen System einen Einfluss auf die Thymozytenentwicklung in vivo.}, subject = {Glucocorticosteroidrezeptor}, language = {de} } @article{ArnholdtGilbertBlanketal.2017, author = {Arnholdt, J{\"o}rg and Gilbert, Fabian and Blank, Marc and Papazoglou, Jannis and Rudert, Maximilian and N{\"o}th, Ulrich and Steinert, Andre F.}, title = {The Mayo conservative hip: complication analysis and management of the first 41 cases performed at a University level 1 department}, series = {BMC Muskoskeletal Disorders}, volume = {18}, journal = {BMC Muskoskeletal Disorders}, number = {250}, doi = {10.1186/s12891-017-1613-2}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-157812}, year = {2017}, abstract = {Background: To prevent bone loss in hip arthroplasty, several short stem systems have been developed, including the Mayo conservative hip system. While there is a plethora of data confirming inherent advantages of these systems, only little is known about potential complications, especially when surgeons start to use these systems. Methods: In this study, we present a retrospective analysis of the patients' outcome, complications and the complication management of the first 41 Mayo conservative hips performed in 37 patients. For this reason, functional scores, radiographic analyses, peri- and postoperative complications were assessed at an average follow-up of 35 months. Results: The overall HHS improved from 61.2 pre-operatively to 85.6 post-operatively. The German Extra Short Musculoskeletal Function Assessment Questionnaire (XSFMA-D) improved from 30.3 pre-operatively to 12.2 post-operatively. The most common complication was an intraoperative non-displaced fracture of the proximal femur observed in 5 cases (12.1\%). Diabetes, higher BMI and older ages were shown to be risk factors for these intra-operative periprosthetic fractures (p < 0.01). Radiographic analysis revealed a good offset reconstruction in all cases. Conclusion: In our series, a high complication rate with 12.1\% of non-displaced proximal femoral fractures was observed using the Mayo conservative hip. This may be attributed to the flat learning curve of the system or the inherent patient characteristics of the presented cohort."}, language = {en} } @article{ScheerVokuhlBlanketal.2019, author = {Scheer, Monika and Vokuhl, Christian and Blank, Bernd and Hallmen, Erika and von Kalle, Thekla and M{\"u}nter, Marc and Wessalowski, R{\"u}diger and Hartwig, Maite and Sparber-Sauer, Monika and Schlegel, Paul-Gerhardt and Kramm, Christof M. and Kontny, Udo and Spriewald, Bernd and Kegel, Thomas and Bauer, Sebastian and Kazanowska, Bernarda and Niggli, Felix and Ladenstein, Ruth and Ljungman, Gustaf and Jahnukainen, Kirsi and Fuchs, J{\"o}rg and Bielack, Stefan S. and Klingebiel, Thomas and Koscielniak, Ewa}, title = {Desmoplastic small round cell tumors: Multimodality treatment and new risk factors}, series = {Cancer Medicine}, volume = {8}, journal = {Cancer Medicine}, number = {2}, doi = {10.1002/cam4.1940}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-228444}, pages = {527-545}, year = {2019}, abstract = {Background To evaluate optimal therapy and potential risk factors. Methods Data of DSRCT patients <40 years treated in prospective CWS trials 1997-2015 were analyzed. Results Median age of 60 patients was 14.5 years. Male:female ratio was 4:1. Tumors were abdominal/retroperitoneal in 56/60 (93\%). 6/60 (10\%) presented with a localized mass, 16/60 (27\%) regionally disseminated nodes, and 38/60 (63\%) with extraperitoneal metastases. At diagnosis, 23/60 (38\%) patients had effusions, 4/60 (7\%) a thrombosis, and 37/54 (69\%) elevated CRP. 40/60 (67\%) patients underwent tumor resection, 21/60 (35\%) macroscopically complete. 37/60 (62\%) received chemotherapy according to CEVAIE (ifosfamide, vincristine, actinomycin D, carboplatin, epirubicin, etoposide), 15/60 (25\%) VAIA (ifosfamide, vincristine, adriamycin, actinomycin D) and, 5/60 (8\%) P6 (cyclophosphamide, doxorubicin, vincristine, ifosfamide, etoposide). Nine received high-dose chemotherapy, 6 received regional hyperthermia, and 20 received radiotherapy. Among 25 patients achieving complete remission, 18 (72\%) received metronomic therapies. Three-year event-free (EFS) and overall survival (OS) were 11\% (±8 confidence interval [CI] 95\%) and 30\% (±12 CI 95\%), respectively, for all patients and 26.7\% (±18.0 CI 95\%) and 56.9\% (±20.4 CI 95\%) for 25 patients achieving remission. Extra-abdominal site, localized disease, no effusion or ascites only, absence of thrombosis, normal CRP, complete tumor resection, and chemotherapy with VAIA correlated with EFS in univariate analysis. In multivariate analysis, significant factors were no thrombosis and chemotherapy with VAIA. In patients achieving complete remission, metronomic therapy with cyclophosphamide/vinblastine correlated with prolonged time to relapse. Conclusion Pleural effusions, venous thrombosis, and CRP elevation were identified as potential risk factors. The VAIA scheme showed best outcome.
