Neben Sarkomen, Hirntumoren, Brustkrebs und Leuk{\"a}mie geh{\"o}rt das NNR-Ca zu den Kerntumoren, durch die das selten vorkommende autosomal dominante Tumor-Pr{\"a}dispositions Syndrom, das Li Fraumeni Syndrom (LFS) gekennzeichnet ist. Das LFS wird mit Keimbahnmutationen im Tumorsuppressor Gen TP53 in Verbindung gebracht. Die vorliegende Arbeit untersucht TP53 Keimbahnmutationen und -polymorphismen und ihre Auswirkung auf klinische Faktoren bei einem großen Kollektiv von erwachsenen NNR-Ca Patienten. Es wurde DNS aus Blut und teilweise aus Tumorgewebe von Patienten aus dem Deutschen Nebennierenrindenkarzinom Register extrahiert und die Exons 2 bis 11 von TP53 sequenziert. Dar{\"u}ber hinaus wurde der Nachweis der Mutationen und eines Loss of Heterozgosity von TP53 im Tumorgewebe und die immunhistochemische F{\"a}rbung von p53 vorgenommen. Die anschließende Auswertung der Daten erfolgte unter Einbeziehung des klinischen Verlaufs der Krankheit bei den Patienten. In dieser Arbeit konnten vier NNR-Ca Patienten (3,9 \%) mit mindestens einer Keimbahnmutation im TP53 identifiziert werden, bei den unter 40-j{\"a}hrigen entspricht dies einem Anteil von 13,0 \%. Unter der Altersgrenze von 40 Jahren sollte daher ein TP53 Mutationsscreening erwogen werden. Die Auswertung der Polymorphismen zeigte, dass diese einen Einfluss auf die Entstehung und den klinischen Verlauf des NNR-Cas zu haben scheinen, jedoch weitere Studien n{\"o}tig sind.}, subject = {TP53}, language = {de} } @article{GalimbertiDell'OssoFenoglioetal.2012, author = {Galimberti, Daniela and Dell'Osso, Bernardo and Fenoglio, Chiara and Villa, Chiara and Cortini, Francesca and Serpente, Maria and Kittel-Schneider, Sarah and Weigl, Johannes and Neuner, Maria and Volkert, Juliane and Leonhard, C. and Olmes, David G. and Kopf, Juliane and Cantoni, Claudia and Ridolfi, Elisa and Palazzo, Carlotta and Ghezzi, Laura and Bresolin, Nereo and Altamura, A.C. and Scarpini, Elio and Reif, Andreas}, title = {Progranulin Gene Variability and Plasma Levels in Bipolar Disorder and Schizophrenia}, series = {PLoS One}, volume = {7}, journal = {PLoS One}, number = {4}, doi = {10.1371/journal.pone.0032164}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-131910}, pages = {e32164}, year = {2012}, abstract = {Basing on the assumption that frontotemporal lobar degeneration (FTLD), schizophrenia and bipolar disorder (BPD) might share common aetiological mechanisms, we analyzed genetic variation in the FTLD risk gene progranulin (GRN) in a German population of patients with schizophrenia (n=271) or BPD (n=237) as compared with 574 age-, gender-and ethnicity-matched controls. Furthermore, we measured plasma progranulin levels in 26 German BPD patients as well as in 61 Italian BPD patients and 29 matched controls. A significantly decreased allelic frequency of the minor versus the wild-type allele was observed for rs2879096 (23.2 versus 34.2\%, P<0.001, OR: 0.63, 95\% CI: 0.49-0.80), rs4792938 (30.7 versus 39.7\%, P=0.005, OR: 0.70, 95\% CI: 0.55-0.89) and rs5848 (30.3 versus 36.8, P=0.007, OR: 0.71, 95\% CI: 0.56-0.91). Mean +/- SEM progranulin plasma levels were significantly decreased in BPD patients, either Germans or Italians, as compared with controls (89.69 +/- 3.97 and 116.14 +/- 5.80 ng/ml, respectively, versus 180.81 +/- 18.39 ng/ml P<0.001) and were not correlated with age. In conclusion, GRN variability decreases the risk to develop BPD and schizophrenia, and progranulin plasma levels are significantly lower in BPD patients than in controls. Nevertheless, a larger replication analysis would be needed to confirm these preliminary results.}, language = {en} } @article{RoeslerSegererMorbachetal.2012, author = {Roesler, Joachim and Segerer, Florian and Morbach, Henner and Kleinert, Stefan and Thieme, Sebastian and R{\"o}sen-Wolff, Angela and Liese, Johannes G.}, title = {P67-phox (NCF2) Lacking Exons 11 and 12 Is Functionally Active and Leads to an Extremely Late Diagnosis of Chronic Granulomatous Disease (CGD)}, series = {PLoS One}, volume = {7}, journal = {PLoS One}, number = {4}, doi = {10.1371/journal.pone.0034296}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-134948}, pages = {e34296}, year = {2012}, abstract = {Two brothers in their fifties presented with a medical history of suspected fungal allergy, allergic bronchopulmonary aspergillosis, alveolitis, and invasive aspergillosis and pulmonary fistula, respectively. Eventually, after a delay of 50 years, chronic granulomatous disease (CGD) was diagnosed in the index patient. We found a new splice mutation in the NCF2 (p67-phox) gene, c.1000+2T -> G, that led to several splice products one of which lacked exons 11 and 12. This deletion was in frame and allowed for remarkable residual NADPH oxidase activity as determined by transduction experiments using a retroviral vector. We conclude that p67-phox which lacks the 34 amino acids encoded by the two exons can still exert considerable functional activity. This activity can partially explain the long-term survival of the patients without adequate diagnosis and treatment, but could not prevent progressing lung damage.}, language = {en} }
