Metabolic syndrome (MeS) is associated with increased PCa aggressiveness and recurrence. We propose C-terminal binding protein 1 (CTBP1), a transcripcional co-repressor, as a molecular link between these two conditions. CTBP1 depletion decreased PCa growth in MeS mice. The aim of this study was to investigate the molecular mechanisms that explain the link between MeS and PCa mediated by CTBP1. We found that CTBP1 repressed several mRNAs and miRNAs including Chloride Channel Accessory 2 (CLCA2) in prostate xenografts developed in MeS animals. CTBP1 bound to CLCA2 promoter and repressed its transcription and promoter activity in PCa cell lines. Furthermore, we found that CTBP1 formed a repressor complex with ZEB1, EP300 and HDACs that modulates the CLCA2 promoter activity. CLCA2 promoted PCa cell adhesion inhibiting Epithelial-Mesenchymal Transition (EMT) and activating CTNNB1 together with epithelial markers (CDH1) induction, and mesenchymal markers (SNAI2 and TWIST1) repression. Moreover, CLCA2 depletion in PCa cells injected s.c. in MeS mice increased the Circulating Tumor Cells (CTCs) foci compared to control. A miRNA expression microarray from PCa xenografts developed in MeS m...

In this study, we found that Lnc-OC1 was significantly higher in PCOS granulosa cells (GCs) compared to non-PCOS GCs. Lnc-OC1 knockdown inhibited cell viability and promoted cell apoptosis, expression of aromatase mRNA and production of estradiol in KGN cells. In PCOS mice, Lnc-OC1 promoted the serum insulin release, production of angiogenesis-related factors and IκBα phosphorylation, which could be partially restored by Lnc-OC1 shRNA. These results suggest that Lnc-OC1 plays an important part in the pathogenesis of PCOS.

Publication date: Available online 15 February 2020Source: Seminars in Cancer BiologyAuthor(s): Cristina Florean, Mario Dicato, Marc DiederichAbstractThe recent advances in cancer immunotherapy confirm the crucial role of the immune system in cancer progression and treatment. Chronic inflammation and reduced immune surveillance are both features of the tumor microenvironment. Strategies aimed at reverting pro-tumor inflammation and stimulating the antitumor immune components are being actively searched, and the anticancer effects of many candidate drugs have been linked to their ability to modulate the immune system.

ConclusionsThe variability of radiocholine uptake in adrenal glands depends probably on overall body metabolism and hypophyseal function expressed by statistically significant correlation with liver and pituitary gland uptake.Predominant focal or mixed with focal areas uptake patterns on positron emission tomography in normal in computed tomography adrenal glands should be assessed with caution to avoid a diagnostic mistake.

Conclusions and Perspectives In this review, we have discussed important milestones from the early description of “Serum-sickness” as being due to antibodies directed against Neu5Gc epitopes all the way to the present-day therapeutic implications of these antibodies in cancer therapy. Some of these milestones have been represented in a concise timeline (Figure 6). While the “Xenosialitis” hypothesis is well-supported in the human-like mouse models, it has yet to be conclusively proven in humans. It remains to be seen if “Xenosialitis” plays a role in other uniquely-human diseases. FI...

Conclusion The expression of the components of the PTN-MK-RPTPβ/ζ axis in immune cells and in inflammatory diseases suggests important roles for this axis in inflammation. Pleiotrophin has been recently identified as a limiting factor of metainflammation, a chronic pathological state that contributes to neuroinflammation and neurodegeneration. Pleiotrophin also seems to potentiate acute neuroinflammation independently of the inflammatory stimulus while MK seems to play different -even opposite- roles in acute neuroinflammation depending on the stimulus. Which are the functions of MK and PTN in chronic neuroinfla...
