It occurs in high levels in the gonads suggesting a potential central role in reproduction. The aim of our study was to assess the effect of PACAP treatment during embryo vitrification on the developmental rate and the expression of the heparin-binding EGF-like growth factor gene (Hbegf). Mouse embryos, obtained from superovulated females were allocated into the four treatment groups. In EM1 and EM2, the embryos were prepared for vitrification in an Equilibration Solution that was supplemented with 1 or 2 μM PACAP1-38, respectively. The embyos in groups CM1 and CM2 were not treated prior to vitrification but were cultured in a medium supplemented with 1 or 2 μM PACAP1-38 after thawing. The Vitrified Control group consisted of embryos vitrified and thawed then cultured without PACAP1-38 treatment. A non-vitrified, non-treated Fresh Control group was also used. After 24 h of culture, the developmental rate of the embryos, as well as the relative expression level of the Hbegf gene, as determined by qPCR, were compared among groups. Higher developmental rate and Hbegf gene expression level were found in the embryos treated with a higher concentration of PACAP. These results indicate that PACAP treatment has a beneficial effect on the survival and development of vitrified/thawed mouse embryos.}, keywords = {PACAP; embryo; Vitrification; cryoprotectant; HB-EGF}, year = {2023}, eissn = {1588-2705}, pages = {112-118} } @article{MTMT:34067933, title = {Diagnostic and Prognostic Value of PACAP in Multiple Myeloma}, url = {https://m2.mtmt.hu/api/publication/34067933}, author = {Tóth, Tünde and Alizadeh, Hussain and Polgár, Beáta and Csalódi, Renáta and Reglődi, Dóra and Tamás, Andrea}, doi = {10.3390/ijms241310801}, journal-iso = {INT J MOL SCI}, journal = {INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES}, volume = {24}, unique-id = {34067933}, issn = {1661-6596}, abstract = {Pituitary adenylate cyclase-activating polypeptide (PACAP) is a multifunctional neuropeptide with well-known anti-inflammatory, antioxidant, antitumor, and immunomodulatory effects. PACAP regulates the production of various proinflammatory factors and may influence the complex cytokine network of the bone marrow microenvironment altered by plasma cells, affecting the progression of multiple myeloma (MM) and the development of end-organ damage. The aim of our study was to investigate the changes in PACAP-38 levels in patients with MM to explore its value as a potential biomarker in this disease. We compared the plasma PACAP-38 levels of MM patients with healthy individuals by ELISA method and examined its relationship with various MM-related clinical and laboratory parameters. Lower PACAP-38 levels were measured in MM patients compared with the healthy controls, however, this difference vanished if the patient achieved any response better than partial response. In addition, lower peptide levels were found in elderly patients. Significantly higher PACAP-38 levels were seen in patients with lower stage, lower plasma cell infiltration in bone marrow, lower markers of tumor burden in serum, lower total urinary and Bence-Jones protein levels, and in patients after lenalidomide therapy. Higher PACAP-38 levels in newly diagnosed MM patients predicted longer survival and a higher probability of complete response to treatment. Our findings confirm the hypothesis that PACAP plays an important role in the pathomechanism of MM. Furthermore, our results suggest that PACAP might be used as a valuable, non-invasive, complementary biomarker in diagnosis, and may be utilized for prognosis prediction and response monitoring.}, keywords = {PACAP; ELISA; multiple myeloma; diagnostic and prognostic factor}, year = {2023}, eissn = {1422-0067} } @article{MTMT:33453105, title = {Modulatory activity of ADNP on the hypoxia‑induced angiogenic process in glioblastoma}, url = {https://m2.mtmt.hu/api/publication/33453105}, author = {D'Amico, Agata Grazia and Maugeri, Grazia and Magrì, Benedetta and Giunta, Salvatore and Saccone, Salvatore and Federico, Concetta and Pricoco, Elisabetta and Broggi, Giuseppe and Caltabiano, Rosario and Musumeci, Giuseppe and Reglődi, Dóra and D'Agata, Velia}, doi = {10.3892/ijo.2022.5462}, journal-iso = {INT J ONCOL}, journal = {INTERNATIONAL JOURNAL OF ONCOLOGY}, volume = {62}, unique-id = {33453105}, issn = {1019-6439}, abstract = {Glioblastoma multiforme (GBM) is a brain cancer with a poor prognosis that affects adults. This is a solid tumor characterized by a high rate of cell migration and invasion. The uncontrolled cell proliferation creates hypoxic niches in the tumor mass, which leads to the overexpression of hypoxia‑inducible factors (HIFs). This induces the activation of the vascular endothelial growth factor (VEGF), which is responsible for uncontrolled neoangiogenesis. Recent studies have demonstrated the anti‑invasive effect of pituitary adenylate cyclase‑activating peptide (PACAP) in GBM. PACAP effects on the central nervous system are also mediated through the activity‑dependent neuroprotective protein (ADNP) activation. To date, no evidence exists regarding its role in GBM. Therefore, the ADNP involvement in GBM was investigated. By analyzing ADNP expression in a human GBM sample through confocal microscopy, a high ADNP immunoreactivity was detected in most glial cells and its predominant expression in hypoxic areas overexpressing HIF‑1α was highlighted. To investigate the role of ADNP on the HIF‑VEGF axis in GBM, a human U87MG GBM cell line was cultured with a hypoxic mimetic agent, deferoxamine, and cells were treated with the smallest active fragment of ADNP, known as NAP. The protein expression and distribution of HIF‑1α and VEGF was detected using western blot analysis and immunofluorescence assay. Results demonstrated that ADNP modulates the hypoxic‑angiogenic pathway in GBM cells by reducing VEGF secretion, detected through ELISA assay, as well as modulating their migration, assessed through wound healing assay. Although deeper investigation is necessary, the present study suggested that ADNP could be involved in PACAP anti‑invasive effects in GBM.}, keywords = {ANGIOGENESIS; HYPOXIA; Vascular endothelial growth factor; glioblastoma multiforme; activity‑dependent neuroprotective protein}, year = {2023}, eissn = {1791-2423} } @{MTMT:33551214, title = {The protective effects of PACAP1-38 on the retinal vasculature and hypoxic molecules in rat glaucoma model}, url = {https://m2.mtmt.hu/api/publication/33551214}, author = {Patkó, Evelin Viktória and Szabó, Edina and Váczy, Alexandra and Molitor, Dorottya and Eniko, Tari and Lina, Li and Adrienne, Csutak and Gabor, Toth and Reglődi, Dóra and Atlasz, Tamás}, booktitle = {XI.

The aim of the present paper was to review the currently available literature regarding the effects of PACAP on cell death in vitro in neural and non-neural cells. Among others, its effect on apoptosis can be detected in cerebellar granule cells against different toxic stimuli. Different neural cell types from the cerebral cortex are also prevented from cell death. PACAP also shows effects on cell death in cells belonging to the peripheral nervous system and protects both neural and non-neural cells of sensory organs. In addition, cell survival-promoting effect can be observed in different peripheral organ systems including cardiovascular, immune, respiratory, gastrointestinal, urinary, and reproductive systems.

The aim of the present study was to determine what proportion of the surgically resected eutopic endometrial samples is suitable for further experiments so that these can be comparable with endometriosis. Final hospital reports and histopathology reports of a 3-year-long period (1162 cases) were analysed. The application of a retrospective screening method promoted the categorization of these cases, and quantification of the categorized cases was accomplished. In addition, results obtained from cultured endometrium samples were also detailed. Only a small number of the harvested endometrial samples was suitable for further molecular analysis, while preoperative screening protocol could enlarge this fraction. Applying clinical and histopathological selection and exclusion criteria for tissue screening and histopathological examination of samples could ensure the comparability of healthy endometrium with endometriosis.
