Parathyroid carcinoma in neurofibromatosis type 1 is extremely rare. Among the reports of neurofibromatosis type 1 with comorbid hyperparathyroidism have been a patient with coincident pheochromocytoma and medullary thyroid cancer, and a patient with a mutation of the RET gene, the causative gene of multiple endocrine neoplasia (MEN). These cases suggest an association between neurofibromatosis type 1 and multiple endocrine tumors, but the detailed mechanism is still unknown. Moreover, a mutation in the HRPT2 gene has been noted as a genetic cause of parathyroid carcinoma, but at presents no genetic link between neurofibromatosis type 1 and a mutation in the HRPT2 gene has been demonstrated, and the association between neurofibromatosis type 1 and parathyroid cancer remains unclear. We have reported an extremely rare case of neurofibromatosis type 1 with coincident hyperparathyroidism that is caused by parathyroid carcinoma.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70249906","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, if ageing is considered a defense mechanism against cancer, caution should be implemented regarding the use of NAD+ and its precursors. In the hypothesis presented NAD+ is shown as an important factor related to cancer formation and prevention. NAD+ depletion with age may play a major role in the process of cancer formation by limiting (1) energy production, (2) DNA repair, (3) genomic stability and signaling. Disruption of any of these processes could increase the cancer risk due to impaired genomic stability. NAD+ content is a critical protective factor in early carcinogenesis and can become detrimental factor later in cancer progression and promotion phase. Namely, NAD+ restoration could prevent or reverse the phenotype of malignant cells at early stages by inducing cellular repair and stress adaptive response as well as regulate cell cycle arrest and apoptotic removal of damaged cells. Contrary, during cancer promotion, progression and treatment increased NAD+ levels could have deleterious effects on the malignancy process due to growth advantage, increased resistance and greater cell survival. NAD+ levels can be increased with exercise, caloric restriction and ingestion of NAD+ precursors and intermediates or could be increased by using PARP and CD 38 inhibitors. The evidence indicating that modulation of NAD+ levels could be important in cancer prevention, initiation and progression phase is presented.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70249746","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is mounting evidence that biophysical signals are integral to the cycle of initiation, progression and death of cancer cells. Innovative technologies that manipulate this vulnerability in solid tumors could effectively be used to perturb only diseased cells and tissues. Not compromising normally functioning cells while controlling tumor progression, is the ultimate goal for evolving cancer therapeutics like Quantum Magnetic Resonance Therapy, headed promisingly in that direction. \u0000Methods: A patented, CE marked device, the CYTOTRON® delivers rotating, target-specific, modulated, safe Radio Frequencies in the presence of an integrated, instantaneous magnetic field. The presumed modulation of the transmembrane potential of tumor cells and downstream cellular signalling by RF for tissue degeneration in cancer underlies Rotational Field Quantum Magnetic Resonance platform technology. Whole body MRI for tissue proton density determinations was used to compute individualized dosimetry to target solitary or multiple regions of interest in the whole body, simultaneously. Exposure to QMRT was for 1 hour daily for 28 consecutive days. Quality of Life assessments, overall survival and tumor stability using RECIST v1.1 were followed up for 12 months. \u0000Results: Significant increase in life expectancy from the predicted to the actual mean (p=2.13 E-12), and improvements in Karnofsky Performance Scale scores (p=7.25 E-06) and Quality of Life scores (p=1.71 E-08 and p=1.91 E-06) were noted. Thirty six of 51 (71 %) terminally ill patients had stable disease one month after completion of QMRT or longer. \u0000Conclusions: Exposure to radiofrequency-mediated QMRT improved life expectancy and quality of life, along with arrest of tumor progression. This therapy can be safely positioned in a palliative care setting, transitioning to mainstream cancer care with more rigorous clinical validation.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70249549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different proton migration inhibitors are being tried, need for developing appropriate transporter with lesser side effects is being felt. These efforts have ignored realising acid-base variations and variant pH leading to impaired glycolysis rate. \u0000Aim:Use of proton rich chemical like hydrochloric acid would rebalance acid-base proportion and bring pH back into accepted range avoiding malignant cell formation. Normalising glycolysis rate would obviate need of developing anti-porter inhibitor compounds. \u0000Design:Hypothesizing; malignancy developed following imbalance between acid-base proportions of intra and extra cellular environment.

Although several risk factors for the development of prostate cancer have been identified, the impact of chronic prostatitis is still a matter of debate. A key event of prostate cancer pathogenesis is the decrease of the homeo box protein NKX3.1 in the luminal epithelial cells of the prostate observed in early pre-cancerous lesions. Furthermore, inactivation of Nkx3.1 in a mouse model led to high incidence of prostatic intraepithelial neoplasia (PIN) formation underscoring the importance of NKX3.1 loss. In this study, we aimed to define the impact of diverse cytokines and growth factors known to be expressed during chronic prostatitis on NKX3.1 expression. \u0000Methods: We determined the NKX3.1 expression in inflamed areas of prostatectomy specimens by immunohistochemistry. NKX3.1 protein and mRNA levels in cytokine and growth factor stimulated PCa cell lines were determined by western blot and RTqPCR. Transcriptional activity of the androgen receptor (AR) was determined by luciferase reporter assays and impact of the AR on NKX3.1 expression by siRNA mediated AR knock down. \u0000Results: Treatment of prostate carcinoma cell lines with epidermal growth factor (EGF) dramatically reduced NKX3.1 protein and mRNA levels, while TNFα or IL-1α had only a moderate effect. Moreover, EGF or a combination of PMA and ionomycin (P+I) also caused diminished levels of the AR. However, while NKX3.1 reduction is observed as early as one hour after stimulation the decrease of AR occurred with a delayed kinetic. We show that P+I-induced NKX3.1 proteolysis is proteasome-dependent and influenced by protein kinase C. \u0000Conclusion: In summary, we provide evidences for a crucial role of inflammatory mitogenic factors leading to reduced NKX3.1 and AR levels which might contribute to the initiation of pre-cancerous PIN lesions.","PeriodicalId":73658,"journal":{"name":"Journal of clinical & experimental oncology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70249507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
