Pleural mesothelioma from fluoro-edenite exposure: PACAP and PAC1 receptor. A preliminary report.
Pleural mesothelioma is a devastating malignancy primarily associated with asbestos exposure. However, emerging evidence suggests that exposure to fluoro-edenite fibers, a naturally occurring mineral fiber, can also lead to the development of pleural mesothelioma. In this study, based on the hypothesis that pituitary adenylate cyclase-activating polypeptide (PACAP) and PACAP-preferring receptor (PAC1R) expressions could be dysregulated in pleural mesothelioma samples and that they could potentially act as diagnostic or prognostic biomarkers, we aimed to investigate the immunohistochemical expression of PACAP and PAC1R in pleural biopsies from patients with pleural mesothelioma exposed to fluoro-edenite fibers. A total of 12 patients were included in this study, and their biopsies were processed for immunohistochemical analysis to evaluate the expression of PACAP and its receptor. The study revealed a correlation between the overexpression of PACAP and PAC1R and shorter overall survival in patients with malignant mesothelioma. These findings suggest that PACAP and PAC1R expression levels could serve as potential prognostic biomarkers for malignant mesothelioma. Furthermore, the immunohistochemical analysis of PACAP and PAC1R may provide valuable information for clinicians to guide therapeutic decisions and identify patients with poorer prognosis.
期刊介绍：
The Journal publishes original papers concerning investigations by histochemical and immunohistochemical methods, and performed with the aid of light, super-resolution and electron microscopy, cytometry and imaging techniques. Coverage extends to:
functional cell and tissue biology in animals and plants;
cell differentiation and death;
cell-cell interaction and molecular trafficking;
biology of cell development and senescence;
nerve and muscle cell biology;
cellular basis of diseases.
The histochemical approach is nowadays essentially aimed at locating molecules in the very place where they exert their biological roles, and at describing dynamically specific chemical activities in living cells. Basic research on cell functional organization is essential for understanding the mechanisms underlying major biological processes such as differentiation, the control of tissue homeostasis, and the regulation of normal and tumor cell growth. Even more than in the past, the European Journal of Histochemistry, as a journal of functional cytology, represents the venue where cell scientists may present and discuss their original results, technical improvements and theories.
