Nevertheless, limitations to an enduring effectiveness of new drugs are anticipated in resistance mechanisms occurring under such treatments. In this study we used CRPC cell models VCaP and LNCaP as well as AR-negative PC-3- and non-neoplastic epithelial BPH-1-cells treated with 5, 10 or 25 mu mol/L abiraterone hydrolyzed from abiraterone acetate (AA). The origin of CYP17A1 up-regulation under AA treatment was investigated in CRPC cell models by qRT-PCR and western-blot procedures. AA treatments of AR positive CRPC cell models led to decreased expression of androgen regulated genes such as PSA. In these cells diminished expression of androgen regulated genes was accompanied by an up-regulation of CYP17A1 expression within short-term treatments. No such effects became evident in AR-negative PC-3 cells. AR directed siRNA (siAR) used in VCaP cells significantly reduced mRNA expression and AR protein abundance. Such interference with AR signalling in the absence of abiraterone acetate also caused a marked up-regulation of CYP17A1 expression. Down-regulation of androgen regulated genes occurs in spite of an elevated expression of CYP17A1, the very target enzyme for this drug. CYP17A1 up-regulation already takes place within such short treatments with AA and does not require adaptation events over several cell cycles. CYP17A1 is also up-regulated in the absence of AA when AR signalling is physically eliminated by siAR. These results reveal an immediate counter-regulation of CYP17A1 expression whenever AR-signalling is inhibited adequately but not a persisting adaptation yielding drug resistance."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft (DFG)"],["dc.identifier.doi","10.1186/2193-1801-3-574"],["dc.identifier.isi","000359105300002"],["dc.identifier.pmid","25332874"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/11151"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/32049"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.relation.issn","2193-1801"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Increased expression of CYP17A1 indicates an effective targeting of the androgen receptor axis in castration resistant prostate cancer (CRPC)"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Based on the hypothesis that PSMA expression can be modulated by variations in androgen deprivation therapy (ADT), we investigated the binding of a PSMA-directed radiopharmaceutical in vitro in order to get an insight of the interactions between altered premedication and PSMA expression before repetitive PSMA-directed PET/CT for therapy response and targeted therapy implementation. Methods: The human castration-resistant PCa cell line VCaP (CRPC) was treated with either 1 nmol/L testosterone (T) over 20 passages yielding the androgen-sensitive cell line (revCRPC) or with 5 mu mol/L abiraterone acetate (AA) generating the abiraterone-tolerant subtype CRPCAA. In these cell lines, T and AA were varied by either supply or withdrawal of T and AA. PSMA expression of the three cell culture models was detected by Western blot and immunohistochemical staining. For quantitative measurement of tracer uptake, 0.3 nmol/L Ga-68-labelled PSMA-HBED-CC peptide (100-300 kBq/ml) was added to different treated parallel cultures (n = 9 each). Time-dependent uptake per 10(6) cells of each culture was calculated and evaluated. PSMA mRNA expression was investigated by qPCR. Results: PSMA expression increased dependently on intensified ADT in all three basic cell lines. Ga-68-PSMA-HBED-CC uptake almost doubled during 3 h in all cell lines (p < 0.01). Compared to the basic cells, pre-incubation with abiraterone for 48 h resulted in a significant increased uptake in CRPC (p < 0.001). In revCRPC, 48-h AA pre-incubation resulted in an eightfold higher uptake after 3 h (p < 0.001). Additional withdrawal of external testosterone increased the uptake up to tenfold (p < 0.01). The increase of PSMA expression upon ADT and AA treatments was confirmed by qPCR and Western blot data. Furthermore, in CRPCAA, 48-h AA withdrawal increased the uptake up to fivefold (p < 0.01). Conclusions: The investigated three PCa cell culture subtypes represent a serial preclinical model of androgen deprivation therapy as a proxy for clinical situations with differing basal PSMA expression. The uptake of PSMA-binding tracers could be stimulated by therapeutic effective short-term variation in premedication in all stages of ADT response. These complex interactions have to be considered in the interpretation of diagnostic imaging using PSMA ligands as well as in the optimal timing of PSMA-based therapies."],["dc.description.sponsorship","Deutsche Forschungsgemeinschaft DFG [TH 389/3-1, BR4700/1-1]"],["dc.identifier.doi","10.1186/s13550-015-0145-8"],["dc.identifier.isi","000364963600001"],["dc.identifier.pmid","26576996"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/12584"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/35393"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Springer"],["dc.publisher.place","Heidelberg"],["dc.relation.issn","2191-219X"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0"],["dc.title","Alterations in androgen deprivation enhanced prostate-specific membrane antigen (PSMA) expression in prostate cancer cells as a target for diagnostics and therapy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Methods: A systematic literature review and meta-analysis was conducted in February 2016. Studies were included if they compared the utilization of influenza vaccination, cholesterol/lipid testing, bone densitometry, or blood pressure measurement among survivors of adulthood cancer to cancer-free controls. Random effects meta-analyses were conducted to pool estimates. Results: Literature search identified 3740 studies of which 10 fulfilled the inclusion criteria. Cancer survivors were significantly more likely to utilize bone densitometry (OR=1.226, 95% CI: 1.114 – 1.350, p<0.001) and influenza vaccination (OR=1.565, 95% CI: 1.176 – 2.082, p=0.002) than cancer-free controls. No statistically significant differences were detected for blood pressure measurement and cholesterol/lipid testing (OR=1.322, 95% CI: 0.812 – 2.151, p=0.261; OR=1.046, 95% CI: 0.96 – 1.139, p=0.304). Conclusions: Cancer survivors were more likely to receive influenza vaccinations and bone densitometry. Future studies should evaluate underlying mechanisms and whether the utilization of preventive services translates into prolonged survival of cancer survivors. Implications for Cancer Survivors: Our meta-analysis demonstrated cancer survivors to be more likely to receive the preventive services such as influenza vaccination and bone densitometry than cancer free controls. Still, these results should be interpreted in the context of suboptimal utilization of preventive services in general, and for cancer survivors in specific.

This phase I/IIa study evaluated safety and immunogenicity of CV9103 in patients with advanced castration-resistant prostate-cancer. Methods 44 Patients received up to 5 intra-dermal vaccinations. Three dose levels of total mRNA were tested in Phase I in cohorts of 3–6 patients to determine a recommended dose. In phase II, 32 additional patients were treated at the recommended dose. The primary endpoint was safety and tolerability, the secondary endpoint was induction of antigen specific immune responses monitored at baseline and at weeks 5, 9 and 17. Results The most frequent adverse events were grade 1/2 injection site erythema, injection site reactions, fatigue, pyrexia, chills and influenza-like illness. Possibly treatment related urinary retention occurred in 3 patients. The recommended dose was 1280 μg. A total of 26/33 evaluable patients treated at 1280 μg developed an immune response, directed against multiple antigens in 15 out of 33 patients. One patient showed a confirmed PSA response.

Data concerning metastatic manifestation and impact on PCa development of mesorectal lymph nodes (MLN) is limited. Our investigation describes MLN metastases as index lesion in 68Ga-PSMA PET/CT imaging for recurrent PCa. Methods: Twelve PCa patients with biochemical recurrence (BCR) after primary therapy who prospectively underwent a baseline 68Ga-PSMA-PET/CT initially showed MLN metastases. Eight of these patients received a follow-up 68Ga-PSMA-PET/CT to evaluate treatment response and further evolution. Prostate-specific antigen (PSA)-levels, changes in PSMA-uptake of MLN metastases and further 68Ga-PSMA PET/CT findings were recorded. Results: Median PSA at the first 68Ga-PSMA-PET/CT was 5.39 ng/ml. In all patients therapeutic management changed after the first 68Ga-PSMA-PET/CT. Androgen deprivation therapy (ADT) was initiated in seven of eight patients, one patient restarted initial ADT. Three patients additionally received salvage radiation therapy (sRT) including the prostatic lodge and docetaxel chemotherapy was started in one case. At follow-up, a decrease of PSA-level was detected in all patients (median 2.05 ng/ml) after median 10 months. In six of eight patients we observed a decrease or complete regress of PSMA-uptake in MLN in the follow-up 68Ga-PSMA-PET/CT. Conclusion: MLN metastases detected by 68Ga-PSMA-PET/CT seem to be a relevant localization of tumor manifestation and may serve as index lesion in the treatment of recurrent PCa.

Methods: Forty consecutive patients undergoing either RALP or ORRP were prospectively included to assess the extent of systemic response. Blood samples were collected before surgery (T1), at the time of prostatectomy (T2), at the time of wound closure (T3), and 12 h (T4), 24 h (T5), and 48 h (T6) after surgery, and assayed for interleukins (IL-6 and IL-10), C-reactive protein (CRP), and hemoglobin. A 2-sided p \\u0026lt; 0.05 was considered to indicate significance. Results: Baseline levels of IL-6, IL-10, and CRP were comparable in both arms of the study. IL-6 and IL-10 increased in both groups during surgery and reached maximum levels at 12 and 24 h after surgery. The RALP and RRP groups differed significantly at T2 (p = 0.009), T3 (p = 0.046), T5 (p = 0.05) and T6 (p = 0.0007) for IL-6, and at T3 (p = 0.05) and T4 (p = 0.05) for IL-10. CRP levels differed significantly at 48 h postoperative (p = 0.0053). The maximum levels of all 3 mediators in the RALP group were significantly lower than those in the open surgery group. Patients in the RALP group experienced less pain from day 2 to 4 according to the Visual Analog Scale (p \\u0026lt; 0.05). Conclusions: The study suggests that IL-6 and IL-10 are useful objective markers for surgical stress and that tissue trauma and activation of post-aggression metabolism seem to be less in RALP compared to ORRP."],["dc.identifier.doi","10.1159/000478027"],["dc.identifier.eissn","1423-0399"],["dc.identifier.issn","0042-1138"],["dc.identifier.pmid","28768259"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/77099"],["dc.language.iso","en"],["dc.notes.intern","DOI Import GROB-354"],["dc.publisher","S.
