Pathol Oncol Res 2019; 26:1651-1656. [PMID: 31512057 DOI: 10.1007/s12253-019-00751-9] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/21/2018] [Accepted: 09/05/2019] [Indexed: 10/26/2022]
Abstract
In this study we aim to demonstrate the value of monoclonal Caveolin 1 expression in distinguishing between malignant pleural mesothelioma and pulmonary adenocarcinoma. Total of 129 cases, consisting of 68 cases of malignant pleural mesothelioma (51 epitheloid, 12 biphasic, and 5 sarcomatoid type) and 61 cases of pulmonary adenocarcinoma were examined and stained with monoclonal Caveolin-1. Caveolin 1 expression with a membranous and /or cytoplasmic pattern was detected only in 32.35% (n:22/68) of malignant pleural mesothelioma and 6.5% (n:4/61) of pulmonary adenocarcinoma cases. This finding suggests that the choice of poly/monoclonal antibody for Caveolin 1 in the differential diagnosis of malignant pleural mesothelioma and pulmonary adenocarcinoma is important.

Abstract
PURPOSE Paclitaxel (PTX) is currently used in combination with cisplatin for Hyperthermic Intraperitoneal Chemotherapy (HIPEC) for the treatment of peritoneal carcinomatosis. Albumin-bound PTX is a promising new drug for HIPEC because of its easy solubility in aqueous perfusion medium and possibly because of the tendency of albumin to cross physiological barriers and accumulate in tumor tissue. METHODS We tested the feasibility of using nab-paclitaxel in rabbits treated by HIPEC for 60 min compared with the classical formulation at an equivalent PTX dose. Samples of perfusate and blood were collected at different time points and peritoneal tissues were collected at the end of perfusion. PTX concentrations were determined by HPLC. The depth of paclitaxel penetration through the peritoneal barrier was assessed by mass spectrometry imaging. RESULTS PTX after nab-paclitaxel treatment penetrated up to 0.63 mm in the peritoneal wall, but after CRE-paclitaxel, it was not detectable in the peritoneum. Moreover, the peritoneal concentration after nab-paclitaxel was five times that after paclitaxel classical formulation. Despite the high levels reached in the peritoneum, systemic exposure of PTX was low. CONCLUSIONS Our results show that nab-paclitaxel penetrates into the abdominal wall better than CRE-paclitaxel, in terms of effective penetration and peritoneal tissue concentration.

Abstract
The aim of the present study was to demonstrate the location of the different members of the caveolin (cav) family in human muscle spindles. Twenty spindles of three human muscles (vastus medialis, ischiocavernosus, bulbospongiosus) from 12 cadavers were immunohistochemically stained for cav-1, cav-2, and cav-3, and the equatorial and polar regions evaluated. All layers of the outer and inner spindle capsule and all blood vessels within the spindle stained for cav-1 and cav-2. In the muscle spindle, intrafusal muscle fibres stained selectively for cav-3, but with a patchy appearance. Caveolinopathies may therefore also include changes in muscle spindle function.

Abstract
The INHAND Project (International Harmonization of Nomenclature and Diagnostic Criteria for Lesions in Rats and Mice) is a joint initiative of the Societies of Toxicologic Pathology from Europe (ESTP), Great Britain (BSTP), Japan (JSTP), and North America (STP) to develop an internationally accepted nomenclature for proliferative and nonproliferative lesions in laboratory animals. The purpose of this publication is to provide a standardized nomenclature for classifying lesions observed in the soft tissues including skeletal muscle as well as the mesothelium of rats and mice. The standardized nomenclature of lesions presented in this document is also available electronically on the Internet (http://www.goreni.org/). Sources of material included histopathology databases from government, academia, and industrial laboratories throughout the world. Content includes spontaneous developmental and aging lesions as well as those induced by exposure to test materials. A widely accepted and utilized international harmonization of nomenclature for lesions in soft tissues, skeletal muscle and mesothelium in laboratory animals will decrease confusion among regulatory and scientific research organizations in different countries and provide a common language to increase and enrich international exchanges of information among toxicologists and pathologists.

Abstract
A large number of immunohistochemical markers that can assist in the differential diagnosis of epithelioid mesotheliomas are currently available. Because these markers are expressed differently in the various types of carcinomas that can metastasize to the serosal membranes and can potentially be confused with epithelioid mesothelioma, their selection for inclusion in a diagnostic panel largely depends on the differential diagnosis, as well as on which ones work the best in a given laboratory. Traditionally, the panels used in the differential diagnosis of epithelioid mesothelioma have consisted of a combination of positive mesothelioma markers and broad-spectrum carcinoma markers. At present, a wide variety of organ-associated carcinoma markers such as thyroid transcription factor-1 and napsin A for the lung, PAX 8 and PAX 2 for the kidney, and Müllerian-derived tumors; gross cystic disease fluid protein-15 and mammaglobin for the breast; and CDX2 for intestinal differentiation are available, which can assist in establishing the site of origin of an adenocarcinoma when included in a diagnostic panel. This article provides updated information on the composition of the panels of markers recommended in the various differential diagnoses.

Abstract
Peritoneal cell suspension is composed of heterogeneous cell population. Macrophages are the most numerous cells among them. They can originate from different sources and can be resident, exudate and elicited. When we used Freund's adjuvant to elicit peritoneal macrophages, cells having large amount of caveolae on their plasma membrane appeared in the peritoneal wash. The number of these caveolae-rich cells increased by the time of the Freund's adjuvant treatment. Although their morphology was different form from the common macrophages, they were labelled with pan-macrophage antibodies. As the origin of these cells is unknown in this work, we tried to find out where they can originate from. Our interest turned towards the mesothelial cells. We found that the adjuvant treatment resulted in significant morphological changes in these cells and stimulate them to leave the surface of the mesentery. By the time of the adjuvant treatment, the macrophage markers expression increased in the mesothelial cells and more cells were found to detach from the mesentery. These results strongly suggest that under special stimuli mesothelial cells can leave the mesentery and differentiate into phagocytotic (macrophage-like) cells. These data raises the idea that mesothelial cells might not entirely differentiated and represent a multipotential cell lineage. To study whether this is the case we used anti-nestin antibody, which is a specific marker for multifunctional, multi-lineage progenitor cells. Mesothelial cells showed strong labelling with this antibody indicating that these cells really represent a 'young', not entirely differentiated cell population.

Abstract
Endocytic pathways have been implicated in polyamine transport in mammalian cells, but specific mechanisms have not been described. We have shown that expression of a dominant negative (DN) form of the GTPase Dynamin, but not Eps15, diminished polyamine uptake in colon cancer cells indicating a caveolar and nonclathrin uptake mode. Polyamines co-sediment with lipid raft/caveolin-1 rich fractions, of the plasma membrane in a sucrose density gradient. Knock down of caveolin-1 significantly increased polyamine uptake. Conversely, ectopic expression of this protein resulted in diminished polyamine uptake. We also found that presence of an activated K-RAS oncogene significantly increased polyamine uptake by colon cancer cells. This effect is through an increase in caveolin-1 phosphorylation at tyrosine residue 14. Caveolin-1 is a negative regulator of caveolar endocytosis and phosphorylation in a K-RAS dependent manner leads to an increase in caveolar endocytosis. In cells expressing wild type K-RAS, addition of exogenous uPA was sufficient to stimulate caveolar endocytosis of polyamines. This effect was abrogated by the addition of a SRC kinase inhibitor. These data indicate that polyamine transport follows a dynamin-dependent and clathrin-independent endocytic uptake route, and this route is positively regulated by the oncogenic expression of K-RAS in a caveolin-1 dependent manner.

Abstract
Caveolin-1 was up-regulated in different drug-resistant cancer cell lines and was suggested to confer drug resistance by different mechanisms. However, the relation of caveolin-1 expression and the clinical response to chemotherapy and prognosis in non-small cell lung cancer (NSCLC) remains unknown. Total 73 NSCLC (stages IIIB and IV) patients who received gemcitabine-based chemotherapy and also had tumour specimens available before treatment were assessed for caveolin-1 expression using immunohistochemistry. Immunoreactivity of caveolin-1 was correlated with the response to chemotherapy, the clinicopathologic features, and the progression-free survival (PFS) and overall survival (OS) of all patients. Positive caveolin-1 immunostaining was found in 12 (16.4%) of the 73 patients. Eight of the twelve had disease progression and the other four patients remained stable after chemotherapy. Patients with caveolin-1 expression had a significantly lower response rate (complete or partial response, 0% versus 37.7%; P=0.01) and a poor PFS and OS (median survival time: PFS, 4.6 months versus 6.1 months, P=0.005; OS, 7.0 months versus 14 months, P<0.001) than those without caveolin-1 expression. Moreover, multivariate analyses indicated that caveolin-1 positivity was an independent prognostic factor for disease-free survival (DFS) (P=0.003) and OS (P=0.008), respectively. Caveolin-1 expression significantly correlated with drug resistance and a poor prognosis in advanced NSCLC patients treated with gemcitabine-based chemotherapy.

Abstract
The introduction of the electron microscope to the study of the biological materials in the second half of the last century has dramatically expanded our view and understanding of the inner workings of cells by enabling the discovery and study of subcellular organelles. A population of flask-shaped or spherical invaginations of the plasma membrane were described and named plasmalemmal vesicles or caveolae. Until the discovery of caveolin-1 as their first molecular marker in early 1990s, the study of caveolae was the exclusive domain of electron microscopists that demonstrated caveolae at different surface densities in most mammalian cells with few exceptions. Electron microscopy techniques in combination with other approaches have also revealed the structural features of caveolae as well as some of their protein and lipid residents. This review summarizes the data on the structure and components of caveolae and their stomatal diaphragms.
