Abstract
Importance Hidradenitis suppurativa (HS) is a disease of the terminal hair follicle in apocrine gland-enriched skin areas, where immunobiology dysregulation of mesenchymal stem cells (MSCs) may have a key role. Objective To investigate the MSC profile in patients with HS and in healthy controls. Design, Setting, and Participants In this prospective case-control study, patients with HS were recruited from the Dermatological Clinic at the Department of Clinical and Molecular Sciences, Università Politecnica delle Marche, Ancona, Italy. Biopsy specimens were analyzed at the Histology Section of the Department of Clinical and Molecular Sciences. Participants included 11 patients with HS and 9 healthy controls, who were recruited into the study between January 20, 2015, and September 20, 2016, and underwent punch biopsy from axillary skin. None of the participants had received any antibiotics (systemic or topical therapy) within almost 12 weeks before the study. Main Outcomes and Measures The immunophenotypic profile of MSCs was characterized following the minimal criteria established by the International Society for Cellular Therapy for the identification of MSCs. Levels of 12 cytokines belonging to helper T-cell subtypes 1, 2, and 17 pathways were examined on the secretome of isolated cells by enzyme-linked immunoabsorbent assay. Results Skin MSCs were characterized in 11 patients with HS (8 women and 3 men; mean [SD] age, 35.8 [7.9] years) and 9 healthy controls (7 women and 2 men; mean [SD] age, 36.7 [6.9] years). The healthy controls were matched with patients with HS for body mass index. Mesenchymal stem cells isolated from patients with HS (HS-MSCs) and from healthy controls (C-MSCs) met the International Society for Cellular Therapy minimal criteria. Compared with C-MSCs, cytokine analyses of HS-MSCs revealed statistically significant overexpression of interleukin (IL) 6 (median [interquartile range {IQR}], 8765.00 [7659.00-9123.00] vs 2849.00 [2609.00-3001.00] pg/mL; P = .008), IL-10 (median [IQR], 29.46 [26.35-35.79] vs 21.36 [19.89-23.33] pg/mL; P = .004), IL-12 (median [IQR], 15.25 [13.27-16.25] vs 11.89 [10.73-12.33] pg/mL; P = .03), IL-17A (median [IQR], 15.24 [13.23-17.24] vs 11.24 [10.28-11.95] pg/mL; P = .008), tumor necrosis factor (median [IQR], 42.54 [42.20-43.94] vs 32.55 [31.78-33.28] pg/mL; P = .004), transforming growth factor β1 (median [IQR], 1728.00 [1535.00-1979.00] vs 500.80 [465.00-634.50] pg/mL; P = .004), and interferon γ (median [IQR], 11.49 [10.71-12.35] vs 9.45 [9.29-10.01] pg/mL; P = .005). Conclusions and Relevance Mesenchymal stem cells isolated from the skin of patients with HS seem to be activated toward an inflammatory status. The imbalance between proinflammatory and anti-inflammatory activities of MSCs favors the hypothesis of their pathogenic involvement in HS.

Abstract
Human aging is a physiological process characterized by a chronic low-grade inflammation. Senescence may affect endothelial cells, subsequently involved in the most common age-related diseases (ARDs), as well as mesenchymal stem cells (MSCs) with an impairment of their properties in tissues regeneration. Endothelial cells seem to be able to exert a paracrine effect on BM-MSCs through the secretion of pro-inflammatory factors. This work is aimed to evaluate if the senescent status of human umbilical vein endothelial cells (HUVECs) could affect bone marrow derived MSCs (BM-MSCs) proliferative ability and stemness. HUVECs were cultured until the senescence status. Young (passage 3) and senescent HUVECs (passage 13) were indirectly co-cultured with BM-MSCs for 8 days in order to evaluate the effect of their senescence status on proliferative ability and stemness of MSCs. The co-culture of senescent HUVECs with BM-MSCs was associated with a reduced proliferative ability of BM-MSCs, an enforced pro-inflammatory phenotype of BM-MSCs (increased synthesis of proinflammatory cytokines such as IL-6 and TNF-α) and an increased expression of miR-126a-3p, in association with a significant decrease of SOX2, a stemmness- associated gene, targeted by miR-126a-3p. A more general IPA analysis, revealed as miR-126a-3p also modulates the expression of IRS1, IRS2, IL6ST and PIK3R2, all targets that enforce the hypothesis that senescent endothelial cells may reduce the proliferative ability and the stemness phenotype of bone marrow-derived mesenchymal stem cells.

Abstract
BACKGROUND CEACAM1, a valuable biomarker for several cancers, have remained unexplored up to the present in laryngeal squamous cell carcinoma (LSCC). We aimed to examine CEACAM1 expression and evaluate its combinational clinical significance for the diagnosis or prognosis and treatment decision making in LSCC. METHODS CEACAM1 expression was assessed by immunohistochemistry in 54 LSCCs and evaluate its correlation with clinical and histopathological features. RESULTS CEACAM subtype 1 (CEACAM1) expression was positive in 50% of the cases. No significant difference was observed in relation to age, gender, tumor size, and tumor stage. CEACAM1 expression correlated with tumor grade, development of local recurrence, node and distant metastasis. Kaplan-Meier survival curves showed that CEACAM1 staining was inversely correlated with both overall and disease-specific 5-year survival. CONCLUSIONS Our study is the first to demonstrate that CEACAM1 expression is associated with an adverse prognosis in LSCC. CEACAM1 is a valuable biomarker and a promising therapeutic target in LSCC.

Abstract
In the last decade, there has been a growing interest about the possible association between anaplastic large cell lymphoma (ALCL) and breast implants (BIA-ALCL). Many variables, such as breast implants texturization, have been investigated. Breast implants often lead to the formation of a periprosthetic capsule, characterized by inflammation. The presence of the inflamed capsule has been found in the majority of patients with BIA-ALCL. Inflammation may be sustained or counteracted by mesenchymal stem cells (MSCs) by the secretion of pro- or anti-inflammatory cytokines. MSCs were isolated from three capsules surrounding micro-textured (micro-MSCs) and from three capsules surrounding macro-textured (macro-MSCs) implants; after characterization, MSCs were co-cultured with KI-JK cells (a cell line derived from the cutaneous form of ALCL). The secretion of cytokines related to inflammation, the proliferation rate, and the expression of genes referred to pro-tumoral mechanisms were evaluated. Co-cultures of KI-JK cells with micro- or macro-MSCs gave the same results about the secretion of cytokines (increase of IL10, G-CSF, and TGF-β1 and decrease of IL4, IL5, IL12, IL13, IL17A, IFN-γ (p < 0.05) with respect to mock sample), expression of selected genes (increase for ACVR1, VEGF, TGF-βR2, CXCL12, and MKi67 (p < 0.05) with respect to control sample), and the proliferation rate (no variation between mock and co-cultured samples). Our results suggest that MSCs derived from capsules surrounding micro- and macro-textured implants display the same effects on the ALCL cells.

Abstract
It was reported recently that allyl isothiocyanate (AITC) could inhibit various types of cancer cell growth. In the present study, we further investigated whether AITC could inhibit the growth of human breast cancer cells. Unexpectedly, we found that AITC did not inhibit, rather slightly promoted, the proliferation of MDA-MB-231 breast cancer cells, although it did have inhibitory effect on MCF-7 breast cancer cells. Cytofluorimetric analysis revealed that AITC (10 µM) did not induce apoptosis and cell cycle arrest in MDA-MB-231 cells. In addition, AITC significantly (p < 0.05) increased the expression of BCL-2 and mTOR genes and Beclin-1 protein in MDA-MB-231 cells. No significant changes in expression of PRKAA1 and PER2 genes, Caspase-8, Caspase-9, PARP, p-mTOR, and NF-κB p65 proteins were observed in these AITC-treated cells. Importantly, AITC displayed cytotoxic effect on MCF-10A human breast epithelial cell line. These observations suggest that AITC may not have inhibitory activity in MDA-MB-231 breast cancer cells. This in vitro study warrants more preclinical and clinical studies on the beneficial and harmful effects of AITC in healthy and cancer cells.

Abstract
Squamous cell carcinoma of the oral cavity represents the sixth most common cancer worldwide and it is often preceded by pre-neoplastic lesions. Sometimes it is still difficult for pathologists to make objective differential diagnoses only on histological characteristics. Tumorigenesis is accompanied by altered expression of cell adhesion molecules, like carcinoembryonic antigen cell adhesion molecule (CEACAM)1. We wanted to investigative CEACAM1 in oral dysplastic lesions, carcinoma in situ (CIS) and oral squamous cell carcinoma (OSCC). We examined immunohistochemical CEACAM1 expression in 50 OSCC, 30 oral CIS and 40 pre-neoplastic lesions and assessed its correlation with clinical and pathological parameters. CEACAM1 was not expressed in normal mucosa, significantly expressed in CIS while it was negative in all the dysplastic lesions. In OSCC, high CEACAM1 expression was associated with tumor grade and inversely correlated with both overall and disease-specific 5-year survival. We showed that CEACAM1 expression is very dynamic: absent in dysplastic lesions, up-regulated in CIS and OSCC. We suggest that CEACAM1 could be a prognostic marker of OSCC and oral CIS. Our most important finding was that it could help pathologists diagnosing oral carcinoma in situ.

Abstract
OBJECTIVE Sacral neuromodulation (SNM) is proposed to treat different anorectal dysfunctions but its mechanism of action is not yet known. Our previous study demonstrated how SNM can significantly increase neuronal nitric oxide synthase NOS (n-NOS) and inducible NOS (i-NOS) expression in the anus and rectum of rats. There are no reports regarding the relation between SNM and NOS in colonic cells: our aim was to assess NOS expression in colonic rat model after SNM. MATERIALS AND METHODS Twenty-six female Sprangue-Dawley rats were considered: group I, normal control rats; group II, sham treatment rats, in whom electrodes for electrical stimulation were placed in S1 foramen bilaterally and left in place, without performing neuromodulation; group III, rats in whom SNM was performed. After 14 days, the rats were sacrificed and we evaluated n-NOS and i-NOS in colonic specimens by immunohistochemistry and Western Blot analysis. RESULTS Western Blot analysis showed that levels of n-NOS and i-NOS were higher in colon of the III group rats respect to the others; in particular, immunohistochemistry revealed that, after neuromodulation, n-NOS expression in the muscle cells and i-NOS expression in glandular epithelium and nervous cells were highly represented (p < 0.05). CONCLUSION Our study showed that in colon, SNM is able to influence NO synthesis, activating n-NOS expression in muscle cells and i-NOS expression in glandular epithelium and nervous cells. Our study showed a complex colonic response to SNM. This experimental model could be applied to better understand the mechanism of action of SNM in bowel dysfunction.

Abstract
Malignant mesothelioma (MM) is a very aggressive, lethal cancer, and its incidence is increasing worldwide. Development of multi-drug resistance, therapy related side-effects, and disease recurrence after therapy are the major problems for the successful treatment of MM. Emerging evidence indicates that dietary phytochemicals can exert anti-cancer activities by regulating microRNA expression. Until now, only one dietary phytochemical (ursolic acid) has been reported to have MM microRNA regulatory ability. A large number of dietary phytochemicals still remain to be tested. In this paper, we have introduced some dietary phytochemicals (curcumin, epigallocatechin gallate, quercetin, genistein, pterostilbene, resveratrol, capsaicin, ellagic acid, benzyl isothiocyanate, phenethyl isothiocyanate, sulforaphane, indole-3-carbinol, 3,3'-diindolylmethane, diallyl disulphide, betulinic acid, and oleanolic acid) which have shown microRNA regulatory activities in various cancers and could regulate MM microRNAs. In addition to microRNA regulatory activities, curcumin, epigallocatechin gallate, quercetin, genistein, resveratrol, phenethyl isothiocyanate, and sulforaphane have anti-mesothelioma potentials, and pterostilbene, capsaicin, ellagic acid, benzyl isothiocyanate, indole-3-carbinol, 3,3'-diindolylmethane, diallyl disulphide, betulinic acid, and oleanolic acid have potentials to inhibit cancer by regulating the expression of various genes which are also known to be aberrant in MM.

Abstract
BAP1 is a gene situated on chromosome 3p in a region that can be modified in renal cell carcinomas (RCCs). Mutations that cause loss of expression of BAP1 frequently occur in primary clear cell renal carcinoma (ccRCC). In a previous work, we observed that loss of nuclear BAP1 expression was crucial in ccRCC progression; in the current study, we investigated BAP1 expression in a large series of small conventional ccRCCs treated with partial nephrectomy, to assess a possible role as biomarker and the prognostic value in terms of patients' survival at long-term follow-up. One hundred sixty-two patients with single pT1 ccRCC were selected from those who underwent surgery at our Institute of Urology between 1987 and 2000. The features considered in this study were gender, age, tumor size, grade, incidence of metastasis, and patient-specific survival; they were correlated with immunohistochemical BAP1 nuclear expression in tumoral tissue. Median follow-up was 197.24 months (range 19 to 274); median survival was 125.34 months (range 5 to 274 months). None of our pT1 ccRCCs showed total loss of nuclear BAP1 staining; we found a significant negative correlation between nuclear BAP1 expression and tumor size and between nuclear BAP1 expression and grade. In small ccRCCs, nuclear BAP1 staining was not correlated with disease-specific 5-year survival.Our data confirm the established role of BAP1 as a tumor suppressor protein. This is the first report where BAP1 has been studied in pT1 ccRCC tumors, but nuclear BAP1 expression cannot help identify patients having high-risk disease in these patients.

Abstract
PURPOSE Progenitor mesenchymal cells (PMCs) have been found also in epithelial tumors and may derive from cancer stem cells (CSCs) by EMT mechanism. In this scenario, the effects of traditionally drugs on PMCs become of primary concern for therapeutic approaches. Previously, we isolated PMCs from acromegalic (GHomas) and not-functioning pituitary adenomas (NFPAs). Here we evaluate: (1) the role of EMT on their origin; (2) the presence of the somatostatin receptors (SSTR1-5); (3) the effects of somatostatin (SST) and its analogues (SSAs) on PMCs proliferation, apoptosis and SSTR1-5 expression. METHODS PMCs were isolated from GHomas and NFPAs; the expression of E-CADHERIN and TGFβRII (referred to EMT), the expression of the SSTR1-5 as well as the proliferation and apoptosis were tested before and after drugs administration. RESULTS Results show a decrease of E-CADHERIN and an increase of TGFβRII, confirming an EMT involvement; SSTR1-5 are more expressed by PMCs from GHomas than from NFPAs. SST and SSAs administration does not affect cell proliferation and SSTR1-5 expression on PMCs from NFPAs while in PMCs from GHomas, cell proliferation showed a marked decrease and a corresponding increase in the expression of SSTR1-2. Apoptosis rate and EMT were not affected by drugs administration. CONCLUSIONS Results indicate as EMT may be related to the presence of PMCs on pituitary tumors; SSAs, currently used in the management of human GHomas, exert anti-proliferative effect also in PMCs that, because of their derivation from CSCs, may be a new meaningful target for drugs treatment.

Abstract
The growing occurrence of bone disorders and the increase in aging population have resulted in the need for more effective therapies to meet this request. Bone tissue engineering strategies, by combining biomaterials, cells, and signaling factors, are seen as alternatives to conventional bone grafts for repairing or rebuilding bone defects. Indeed, skeletal tissue engineering has not yet achieved full translation into clinical practice because of several challenges. Bone biofabrication by additive manufacturing techniques may represent a possible solution, with its intrinsic capability for accuracy, reproducibility, and customization of scaffolds as well as cell and signaling molecule delivery. This review examines the existing research in bone biofabrication and the appropriate cells and factors selection for successful bone regeneration as well as limitations affecting these approaches. Challenges that need to be tackled with the highest priority are the obtainment of appropriate vascularized scaffolds with an accurate spatiotemporal biochemical and mechanical stimuli release, in order to improve osseointegration as well as osteogenesis.

Abstract
BACKGROUND Inflammation and tumor are now an inseparable binomial. Inflammation may also derive by the use of breast implants followed by the formation of a periprosthetic capsule. It is known that tumor cells, in an inflamed microenvironment, can profit by the paracrine effect exerted also by mesenchymal stem cells (MSCs). Here we evaluated the role of inflammation on the immunobiology of MSCs before and after cocultures with cells derived from breast adenocarcinoma. METHODS MSCs derived from both inflamed (I-MSCs) and control (C-MSCs) tissues were isolated and cocultured with MCF7 cells derived from breast adenocarcinoma. Before and after cocultures, the proliferation rate of MCF7 cells and the expression/secretion of cytokines related to inflammation were tested. RESULTS Before cocultures, higher levels of cytokine related to chronic inflammation were detected in I-MSCs than in C-MSCs. After cocultures with MCF7, C- and I-MSCs show a variation in cytokine production. In detail, IL-2, IL-4, IL-5, IL-10, IL-13, TGF-β and G-CSF were decreased, whereas IL-6, IL-12, IFN-γ, and IL-17 were oversecreted. Proliferation of MCF7 was significantly increased after cocultures with I-MSCs. CONCLUSIONS Inflammation at the site of origin of MSCs affects their immunobiology. Even if tumor cells increased their proliferation rate after cocultures with I-MSCs, the analysis of the cytokines, known to play a role in the interference of tumor cells with the host immune system, absolves completely the breast implants from the insult to enforce the risk of adenocarcinoma.

Abstract
OBJECTIVE To evaluate prospectively the effect of etanercept (a tumour necrosis factor [TNF]-α inhibitor) on vascular endothelial growth factor (VEGF) production by mesenchymal stem cells (MSC) from patients with psoriasis. METHODS MSCs from lesional and perilesional skin were isolated, cultured and characterized. VEGF production was evaluated at baseline and after 12 weeks' etanercept treatment. RESULTS Etanercept treatment resulted in significant reductions in VEGF production compared with baseline in both lesional MSCs (256.42 ± 3.07 pg/ml per 106 cells at baseline vs 27.66 ± 2.03 pg/ml per 106 cells after treatment) and perilesional MSCs (235.03 ± 2.52 pg/ml per 106 cells vs 41.65 ± 4.72 pg/ml per 106 cells). CONCLUSIONS Etanercept reduces the production of VEGF in MSCs, which may modulate angiogenesis and contributes towards preventing the start of the "psoriatic march".

Abstract
Healing of skeletal defects is strictly dependent on osteogenesis and efficient vascularization of engineered scaffolds. Insulin-like growth factor-1 (IGF-1) and vascular endothelial growth factor (VEGF) are both involved in these processes. The in vitro administration of IGF-1 in association with VEGF is able to modulate the osteoblastic or endothelial commitment of mesenchymal stromal cells (MSCs) of different origins (e.g. periosteum and skin). In the present study, in order to deepen a possible paracrine effect of IGF-1 and VEGF on periosteum-derived progenitor cells (PDPCs) and skin-derived MSCs (S-MSCs), a Transwell coculture approach was used. We explored the genes involved in endothelial and osteoblastic differentiation, those modulating mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3'-kinase (PI3K)-AKT signaling pathways as well as genes implicated in stemness (i.e. Sox2, Oct4, and Nanog). Periosteal cells, which are typically committed toward osteoblastogenesis, are driven in the direction of endothelial gene expression when influenced by S-MSCs. The latter, once influenced by PDPCs, lose their endothelial commitment and increase the expression of osteoblast-associated genes. PI3K/AKT and MAPK signaling pathways seem to be markedly involved in this behavior. Our results evidence that paracrine signals between MSCs may differently modulate their commitment in a bone microenvironment, opening stimulating viewpoints for skeletal tissue engineering strategies coupling angiogenesis and osteogenesis processes.

Abstract
INTRODUCTION BRCA1-associated protein 1 (BAP1) is a gene situated on chromosome 3p in a region that is deleted in more than 90% of renal cell carcinomas (RCCs). In the present study, we studied BAP1 immunohistochemical expression in a large series of conventional clear cell RCCs (ccRCCs) treated with radical nephrectomy; we assessed the prognostic value of their expression in terms of patients׳ survival at long-term follow-up. MATERIALS AND METHODS A total of 154 consecutive patients with ccRCC were selected from a prospective database and considered for the study purpose; all patients were treated with radical nephrectomy and lymphadenectomy at our Institute of Urology between 1983 and 1985. The features considered in this study were tumor size, grade and stage, vascular and capsular invasion, incidence of metastasis, and patient-specific survival; all these parameters were correlated with immunohistochemical cytoplasmic and nuclear expression of BAP1 in tumoral tissue. RESULTS Median follow-up was 196.18 months and median survival was 125.34 months. Nuclear BAP1 expression showed a high frequency of loss in tumoral cells; nuclear BAP1-negative tumors had higher tumor size, higher Fuhrman grade, and higher stage, a greater amount of vascular and capsular invasion and a higher incidence of metastases. In multivariate analysis, pathological stage and nuclear BAP1 expression resulted independent prognostic factors. CONCLUSION We have demonstrated that nuclear BAP1 expression is a marker of prognosis in ccRCC, having an influence on cancer-specific survival. The clinical importance for BAP1 will be realized with the identification and application of targeted therapies and with individualized approaches in the adjuvant setting or in the metastatic setting or in both the settings.

Abstract
Bone tissue engineering approaches are encouraging for the improvement of conventional bone grafting technique drawbacks. Thanks to their self-renewal and multi-lineage differentiation ability, stem cells are one of the major actors in tissue engineering approaches, and among these adult mesenchymal stem cells (MSCs) hold a great promise for regenerative medicine strategies. Bone marrow MSCs (BM-MSCs) are the first- identified and well-recognized stem cell population used in bone tissue engineering. Nevertheless, several factors hamper BM-MSC clinical application and subsequently, new stem cell sources have been investigated for these purposes. The fruitful selection and combination of tissue engineered scaffold, progenitor cells, and physiologic signaling molecules allowed the surgeon to reconstruct the missing natural tissue. On the basis of these considerations, we analyzed the capability of two different scaffolds, planned for osteochondral tissue regeneration, to modulate differentiation of adult stem cells of dissimilar local sources (i.e., periodontal ligament, maxillary periosteum) as well as adipose-derived stem cells (ASCs), in view of possible craniofacial tissue engineering strategies. We demonstrated that cells are differently committed toward the osteoblastic phenotype and therefore, taking into account their specific features, they could be intriguing cell sources in different stem cell-based bone/periodontal tissue regeneration approaches.

Abstract
OBJECTIVE to investigate the role of CD- 44 immunohistochemical expression within tumoural and non-tumoural tissue, aiming to understand if it can help us to predict the need of performing inguinal lymph nodes dissection to complete surgery of the penis. MATERIALS AND METHODS CD44 immunohistochemical expression was investigated in tissue specimens from 39 patients with squamous cell carcinoma of the penis who underwent partial or total penectomy between 1987 and 2008. Patient age, tumour size, and grade; CD44 intensity score, cytological expression, topographic and distribution pattern were evaluated by immunohistochemistry on archived material and correlated with disease-specific survival. RESULTS mean patients age was 67.7 years; mean followup was 130.44 months. Bilateral inguinal lymphadenectomy was performed in 14 patients; there were 8 N+ patients (23.5%). pTis-pT1 vs. > pT1 and the EAU classification of risk group resulted to be predictive of lymph nodal metastases at univariate analysis (respectively p = 0.006 and p = 0.045), but not the grading. The intensity score, cytological expression, topographic and distribution pattern of CD44 staining did not correlate with stage, grade and lymph nodes metastases. All disease related deaths occurred only in patients showing an high CD44 intratumoral expression, but this correlation is not statistically significant. Multivariate analysis showed that only lymph node metastasis was an independent prognostic factor predictive of lymph nodes metastases. CONCLUSIONS CD44 expression in patients with squamous cell carcinoma of the penis is not able to predict the need of performing inguinal lymphadenectomy; staging and the EAU classification of risk group resulted to be predictive of lymph nodal metastases.

Abstract
AIM To investigate hypoxia inducible factor-1α's (HIF-1α) immunohistochemical expression in clear cell renal cell carcinoma (ccRCC) treated with radical nephrectomy. PATIENTS AND METHODS One hundred and forty-eight patients were considered from those who underwent radical nephrectomy between 1983 and 1993. Archived materials were retrieved from the Institute of Pathological Anatomy for immunostaining. The features considered on the histological specimens were tumor stage, grade, as well as cellular and vascular HIF-1α expression. All considered parameters were correlated with time to recurrence (TTR) and overall survival (OS). RESULTS TTR was significantly longer in patients with low cellular HIF-1α expression; patients' survival was higher in those with low HIF-1α expression. Regarding vascular HIF-1α expression, the differences were not statistically significant when considering TTR and OS. On univariate analysis, age, clinical stage and HIF-1α cellular expression showed a significant association with OS. CONCLUSION Cellular HIF-1α is an important indicator of prognosis in patients with ccRCC; high HIF-1α expression predicts poor survival.

Abstract
OBJECTIVES Vascular endothelial growth factor (VEGF) is a potent inducer of tumor angiogenesis and represents the key element in the pathogenesis of clear cell renal cell carcinoma (ccRCC). The aim of this study was to investigate the use of tumor VEGF expression as a parameter to identify tumor stage and prognostically different patient groups. METHODS AND MATERIALS We retrospectively collected clinical data of 137 patients treated with partial or radical nephrectomy at our institutions for organ-confined, locally advanced, and metastatic ccRCCs between 1984 and 2013. Tumor cell VEGF immunohistochemical expression was compared with pathological and clinical features including age, sex, tumor stage, and Fuhrman grade. Comparison of VEGF expression levels between tumor stages was performed via Kruskal-Wallis nonparametric test. Survival analysis was conducted via Kaplan-Meier product-limit method, and Mantel-Haenszel log-rank test was employed to compare survival among groups. RESULTS Median age at diagnosis was 61 years (range: 33-85 y). Tumor stage was pT1N0M0 in 67 patients (49%), pT2N0M0 in 5 (4%), and pT3N0M0 in 25 (18%), while 40 patients (29%) had metastatic tumors at diagnosis. Fuhrman nuclear grade was G1 in 22 patients (16%), G2 in 60 (44%), G3 in 33 (24%), G4 in 13 patients (9%), and unknown in 9 patients. Tumor VEGF was differentially expressed among different stages (P<0.001) and in low (G1-2) and high (G3-4) Fuhrman grade tumors (P<0.001). No significant differences were found when stratifying by sex (P = 0.06) or age (P = 0.29). Median overall survival (OS) from partial or radical nephrectomy was 161 months (range: 1-366). We observed a significantly longer OS in patients with low (<25%) vs. high (>25%) VEGF expression levels (median OS 206 vs. 65 mo, P<0.001). CONCLUSIONS Our data show that tumor cell VEGF expression is significantly associated with tumor stage and Fuhrman grade and is able to predict patient outcome, suggesting a potential use of this parameter in identifying prognostically different patients with ccRCC.

Abstract
Impaired male fertility may have a variety of causes, among which asthenozoospermia. In its etiology, several bioactive substances, such as cytokines may be involved. In this context, our aim was to evaluate the expression of interleukin-1β, cyclooxygenase-2, and hypoxia-inducible factor-1α, in spermatozoa isolated from normospermic fertile donors and asthenozoospermic infertile patients. We evaluated twenty-eight infertile patients affected by idiopathic asthenozoospermia and twenty-three normospermic fertile donors, age-matched. Sperm parameters were evaluated; immunohistochemical analysis and enzyme-linked immunosorbent assay were then performed in isolated spermatozoa. Spermatozoa from the asthenozoospermic group presented an increased expression of IL-1β, COX-2, and HIF-1α compared with the normospermic fertile subjects. Our results can lead us to speculate that the increased expression of these substances may influence sperm motility. Nevertheless, further studies are needed in order to assess whether these bioactive mediators have a potential relevance as targets in future therapeutic strategies for the treatment of male infertility.

Abstract
Frontotemporal lobar degeneration (FTLD) and Alzheimer's disease (AD) represent the most frequent causes of early-onset and late-onset degenerative dementia, respectively. A correct diagnosis entails the choice of appropriate therapies. In this view the present study aimed to identify biomarkers that could improve the differential diagnosis. We recently found an overexpression of platelet amyloid precursor protein (APP) in AD; furthermore, recent studies have suggested the presence of changes in APP processing in FTLD. In this context, we analyzed the mRNA expression level of Total APP (TOT) and APP containing a Kunitz-type serine protease inhibitor domain (KPI) in platelets obtained from AD patients, subjects with FTLD, and healthy subjects. In addition, we evaluated the correlation between platelet APP mRNA expression levels and cognitive impairment.Differential gene expression measurements revealed a significant up-regulation of APP TOT and APP KPI in both AD and FTLD patients compared to the controls (being AD/Controls: 1.67 for APP TOT and 1.47 for APP KPI; FTLD/Controls: 1.62 for APP TOT and 1.51 for APP KPI; p < 0.05), although it is interesting to note that in FTLD patients this expression did not correlate with the severity of cognitive impairment.This could be related to a reduced beta-amyloid (Aβ) formation, caused by an alteration of secretase enzymatic activity, even though a post-transcriptional regulation of APP mRNAs in FTLD cannot be excluded.

Abstract
AIM To verify whether vascular endothelial growth factor (VEGF) is associated with distant metastasis free survival (DMFS) and Overall Survival (OS) of patients with renal cell carcinoma (RCC) treated with sunitinib. PATIENTS AND METHODS We have studied 41 patients with metastatic RCC treated with radical nephrectomy, between 2008 and 2010, and sunitinib. Pathological features were compared with the Memorial Sloan-Kettering Cancer Center (MSKCC) score, DMFS, and with OS, and PFS after first-line therapy. RESULTS Tumor stage and grade, VEGF expression and H-score correlated with MSKCC score, DMFS, and with OS; VEGF expression correlated with stage and OS. Patients with higher H-score and higher VEGF expression had a significantly shorter survival; OS after first-line sunitinib therapy and PFS correlated with MSKCC score and DMFS but not with VEGF expression and H score. CONCLUSION Our data suggest the potential use of tumor cell VEGF expression as a prognostic marker for DMFS and OS, but VEGF does not appear promising as a marker of response to therapy.

Abstract
OBJECTIVE To assess the physicochemical characteristics of sperm plasma membrane and to evaluate the immunohistochemical expression of transmembrane and cytoskeletal proteins in spermatozoa isolated from normospermic fertile donors and asthenozoospermic infertile patients. DESIGN Case-control study. SETTING Academic male infertility center. PATIENT(S) Twenty-five infertile patients affected by idiopathic asthenozoospermia and 21 age-matched normospermic fertile donors. INTERVENTION(S) Sperm parameters were evaluated; membrane fluidity and hydration studies, and immunohistochemical analysis were performed in isolated spermatozoa. MAIN OUTCOME MEASURE(S) Semen analyses to ascertain volume, sperm count, motility, and morphology; then membrane fluidity and hydration studies and immunohistochemical analysis were performed on isolated spermatozoa. RESULT(S) Spermatozoa from the asthenozoospermic group exhibited a reduced fluidity at the lipid-water interface level, an increased fluidity of the deeper portion of the bilayer, and a lower plasma membrane hydration than normospermic cells. Moreover, the immunohistochemical expression of ezrin, Cdc42, CD9, F-actin, and β-tubulin was higher in normospermic samples. CONCLUSION(S) Our results together assume that a cytoskeletal reorganization induced by a disturbance in the physicochemical features of sperm plasma membrane, and potentially mediated by ezrin, Cdc42, and tetraspanin CD9, could have a role in idiopathic asthenozoospermia.

Abstract
Mineral fibers are potential carcinogens to humans. In order to help clarify the etiology of the pathological effects of asbestos, cellular reactions to natural and synthetic asbestos fibers were compared using a lung alveolar cancer cell line (A549 epithelial cells), considered the first target of inhaled micro-environmental contaminants. Natural asbestos tremolite (NAT) fibers were collected from rocks in NW Italy. Synthetic asbestos tremolite (SAT) was iron-free and therefore considered as standard tremolite. Both fibers, subjected to mineralogical characterization by X-ray powder diffractometry, electron microscopy and energy dispersive spectrometry, fell within the definition of respirable and potentially carcinogenic fibers. Several signs of functional and structural cell damage were found after treatment with both fibers, documented by viability, motility, and morphological perturbations. Phalloidin labeling showed irregular distribution of cytoskeletal F-actin, whereas immunohistochemical investigations showed abnormal expression of VEGF, Cdc42, β-catenin, assessed as risks indicators for cancer development. Both fibers caused significant loss of viability, even compared to UICC crocidolite, but, while SAT fibers exerted a more direct cytotoxic effect, survival of damaged cells expressing high VEGF levels was detected after NAT contact. This in vitro pilot study outlines potential health risks of NAT fibers in vivo related to their iron content, which could trigger signaling networks connected with cell proliferation and neoplastic transformation.

Abstract
OBJECTIVE Oxidative stress may affect the functionality of placental mitochondria, thus contributing to serious complications. For this reason research of protective substances is of great importance. Our aim was to evaluate, in mitochondria isolated from human term placentas, the effect of in vitro glutamate supplementation on their susceptibility to oxidation, on the chemico-physical characteristics of mitochondrial membranes, and on peroxidase and nitric oxide synthase (NOS) activities. METHODS The study was performed on mitochondria isolated from 20 healthy human term placentas. Specific exclusion criteria were: conception by assisted reproduction, chromosomal or other fetal, uterine or placental anomalies, gestational diabetes, preeclampsia, intrauterine growth restriction (IUGR), a history of smoking and hypertension, proteinuria, renal, cardiovascular, hepatic, and endocrine disease, metabolic disorders, and current infection or history of all types of infection. RESULTS Incubation with glutamate determined a reduced susceptibility to oxidative stress, an increase in mitochondrial membrane fluidity, and a decrease of both peroxidase and NOS activities. CONCLUSIONS On the basis of the observed results, we can hypothesize a role for glutamate in the control of lipid peroxidation extent in physiological pregnancies, as well as in the prevention of free radical-linked complications that can affect the health of both mother and fetus.

Abstract
OBJECTIVE To characterize the expression pattern of constitutive and inducible nitric oxide synthase (NOS) in spermatozoa isolated from normospermic fertile donors and asthenozoospermic infertile patients, by means of immunohistochemistry. Also to evaluate the immunohistochemical expression of citrulline, a marker of NOS activity, and nitrotyrosine, which indicates the formation of peroxynitrite, which may affect sperm functionality through its cytotoxic action. DESIGN Prospective study. SETTING Academic male infertility center. PATIENT(S) Twenty-nine infertile patients affected by idiopathic asthenozoospermia and 26 age-matched normospermic fertile donors. INTERVENTION(S) Sperm parameters were evaluated, and immunohistochemical analysis was performed in isolated spermatozoa. MAIN OUTCOME MEASURE(S) Semen analyses, to ascertain volume, sperm count, motility, and morphology. Immunohistochemical expression of NOS isoforms, citrulline, and nitrotyrosine. RESULT(S) Constitutive NOS expression was greater in spermatozoa isolated from normospermic fertile donors. In contrast, the immunohistochemical expression of inducible NOS and nitrotyrosine was higher in asthenozoospermic samples. Our data concerning citrulline indicated enhanced NOS activity in sperm from idiopathic asthenozoospermic patients. CONCLUSION(S) Our results support the hypothesis that increased NOS activity and an excess of tyrosine nitration may affect the functional characteristics of spermatozoa in idiopathic asthenozoospermia.

Abstract
OBJECTIVES We investigated the in vivo efficacy of tigecycline, a new glycylcycline (a tetracycline derivative), in the management of methicillin-resistant Staphylococcus aureus (MRSA)-infected experimental surgical wounds in rats. The main outcome measures were quantitative bacterial culture, histological examination and immunohistochemical expression of matrix metalloproteinase-9 (MMP-9) and collagen IV. METHODS An animal model was used to compare the in vivo efficacy of teicoplanin and tigecycline in the treatment of burn wound infections by S. aureus. A copper bar, heated in boiling water, was placed on the paraspinal site of each rat, resulting in full thickness burns. A small gauze was placed over each burn and then inoculated with 5 × 10(7) cfu of S. aureus ATCC 43300. To mimic the clinical situation in burn patients, surgical debridement was performed 48 h after the injury. The wounds were left to heal by secondary intention. The study included an uninfected control group that did not receive any treatment, a contaminated group that did not receive any treatment, and two contaminated groups treated with intraperitoneal tigecycline (2 mg/kg) and teicoplanin (7 mg/kg), respectively. RESULTS All antibiotic treatments were significantly effective. Tigecycline showed the highest antimicrobial activity, with a better impact on histological results. Infected rats treated with tigecycline showed a significant decrease in MMP-9 expression both in epithelium and in dermis compared with rats treated with teicoplanin. CONCLUSIONS Tigecycline, besides its antimicrobial activity, exerts an important modulatory effect on MMP-9, accelerating wound healing in staphylococcal-infected burns.

Abstract
BACKGROUND It has been previously observed that the amniotic fluid obtained from Down's syndrome (DS) pregnancies showed lower levels of vascular endothelial growth factor (VEGF) and higher levels of nitric oxide (NO) with respect to the controls, suggesting the presence of an imbalance between placental vascularization and altered endothelial function. The aim of our study was to evaluate the immunohistochemical expression and localization of VEGF and nitric oxide synthase (NOS) isoforms in cultured amniotic fluid mesenchymal stem cells (AF-MSCs) isolated from normal euploid pregnancies and pregnancies complicated by trisomy 21. In addition, we measured the VEGF and NO content in cell culture supernatants to analyse their production by AF-MSCs. MATERIALS AND METHODS AF-MSCs were obtained from women with foetal DS and controls matched for age and gestation, and expanded in culture. The cells were then evaluated for the immunohistochemical expression of VEGF and NOS isoforms, as well as for the release of VEGF and NO. RESULTS Our analyses showed that both the VEGF expression and production were significantly lower in DS-AF-MSCs with respect to the controls. As regards NOS, immunohistochemical expression of eNOS was significantly reduced in DS-AF-MSCs, whereas the nNOS and iNOS were similarly immunoexpressed in both groups of cells. Moreover, we observed that the NO content was significantly higher in medium derived by DS-AF-MSCs. CONCLUSIONS Our study shows, for the first time, the differences between AF-MSCs isolated from control and trisomy 21 pregnancies and suggest an involvement of NO and VEGF in the physiopathological mechanisms associated with DS pregnancy.

Abstract
The mesenchymal stem cells (MSCs) are able to accumulate at the site of tissue damage. For this reason, they must transmigrate across the endothelium. In this study, we focused on skin-derived MSCs (S-MSCs), because the skin represents a useful stem cell source, and we analysed the VEGF released by S-MSCs, because it is known to promote endothelial cell proliferation and vascular permeability. Moreover, we evaluated the influence of S-MSC-conditioned medium on human aortic endothelial cell intracellular calcium concentration ([Ca(2+)](i)) and nitric oxide (NO) production, given their important role in endothelial permeability modulation. Our results suggest that human S-MSCs may interact with the endothelium via paracrine mechanisms, probably leading to an alteration of the endothelial barrier. Consequently, we could hypothesize that a therapeutic approach based on human skin-derived MSCs may have a positive effect on tissue repair.

Abstract
In the last years, physical and chemical methods of plasmid delivery have revolutionized the efficiency of nonviral gene transfer, and the success of gene therapy is largely dependent upon the development of gene-delivery methods. The nonviral techniques that lead to a direct transfer of DNA into tissue fragments, like electroporation (EP) and lipofection delivery systems are still insufficiently investigated. Our aim was to test the efficiency of EP and lipofection protocols in endometrial and testicular tissue fragments, using a naked plasmid DNA encoding green fluorescent protein (GFP). Because the transfection efficiency depends upon several factors, we tried to optimize the transfection conditions by testing different lipofectamine 2000 and plasmid ratios, electrical parameters, and culture after transfection. Our results show that these two nonviral methods of gene delivery are feasible and efficient in gene transfection of endometrial and testicular tissue biopsies. We found that the most performing ratio of plasmid:lipofectamine was 10:50 for transient lipofection, whereas two pulses for 10 s at 960 microF of capacitance, 200 V of voltage were the most favorable electrical parameters for EP efficiency in the presence of 5 microL of phMGFP plasmid. After lipofection and EP, the highest GFP intensity was observed respectively after 48 and 72 h of tissue fragment culturing. In conclusion, nonviral methods are attractive for an improvement of the gene therapy and our protocol could provide useful indications for in vivo gene therapy applications.

Abstract
Researchers are testing different treatments to induce modifications in both chemical composition and topography of implant surface, with the aim to ameliorate bone-to-implant contacts and hence improve osseointegration processes and biomechanical properties in the short and long-term. Aim of the present research was the evaluation of MG63 osteoblast-like cells behaviour on polymeric coatings, electrosynthesized on titanium substrates, differently modified in order to improve implant performances both in terms of osseointegration and infection prevention. Cell viability data and scanning electron microscopy morphological observations were consistent with a good compatibility of modified electrosynthesized coatings and suggest the use of this procedure to produce new bioactive titanium coatings for implant surgery.

Abstract
Tendons have poor spontaneous regenerative capabilities, and complete regeneration is never achieved despite intensive remodeling. In this in vitro study, we characterized two multilamellar collagen I membranes differing in the arrangement of collagen fiber deposition (oriented vs. nonoriented) and compared their mechanical properties. Human dermal fibroblasts and tenocytes were seeded on the two membranes to evaluate the effect of fiber orientation on cell viability and cytoskeletal organization. Results demonstrate that the multilamellar collagen I membrane with oriented fibers has the better mechanical properties and affords optimum cell proliferation and adhesion. Its fiber arrangement provides an instructive pattern for cell growth and may serve to guide the alignment of cells migrating from the ends of a crushed or frayed tendon to obtain a strong, correctly structured tendon, thus providing a viable clinical option for tendon repair.

Abstract
Recent reports have indicated that, as well as having antiresorptive effects, bisphosphonates could have an application as anti-inflammatory drugs. Our aim was to investigate whether this anti-inflammatory action could be mediated by the nitric oxide (NO) released by the leukocytes migrating to the site of inflammation. In particular, we investigated in vitro the intracellular calcium concentration ([Ca2+](i)), the level of NO released by PMN and platelets, and the PMN myeloperoxidase activity after incubation with disodium pamidronate, since there was a postulated modulatory effect of this aminosubstituted bisphosphonate on leukocytes both in vitro and in vivo. Our data shows that the pamidronate treatment provoked a significant increase in the [Ca2+](i) parallel to the enhancement in NO release, suggesting a possible activation of constitutive nitric oxide synthase, while the myeloperoxidase activity was significantly reduced. In conclusion, we hypothesized that treatment with pamidronate could stimulate NO-production by cells present near the bone compartment, thus constituting a protective mechanism against bone resorption occurring during inflammation. In addition, PMN- and platelet-derived NO could act as a negative feed-back signal to restrict the inflammatory processes.

Abstract
CD38 is a type II transmembrane glycoprotein found mainly on the plasma membrane involved in the metabolism of cADPR and NAADP, two nucleotides with calcium mobilizing activity independent of inositol trisphosphate. Recent data report the presence of CD38 in different cellular compartments raising new questions about its effective role in cellular metabolism. In rat hepatocyte nuclei, CD38 has been proposed as a responsive to cADPR integral inner membrane protein suggesting that the nuclear envelope may also be an important source of Ca2+ stores. Further reports indicating that CD38 is localized in nuclear compartments in a variety of cell types and tissues including brain, liver, eye, spleen, and bone raise the condition of resolving the question concerning the effective presence of CD38 within the nucleus. Here we report data supporting the presence of CD38 at nuclear level independently of expression of surface CD38. We utilized two different human leukemia cell lines expressing or not expressing CD38 molecule on their cell surface. The morphological and biochemical results including enzymatic activity and proteomic determinations explain the effective nuclear localization of CD38 in human Raji and K562 cells. Since cell nucleus is a complex and highly dynamic environment with many functionally specialized regions, the nuclear localization of specific proteins represents an important mechanism in signal transduction. The presence of CD38 at the interchromatin region whether linked to nuclear scaffold or stored in nuclear structures as micronuclei and Cajal bodies co-localizing with coilin, suggests its involvement in nuclear processes including transcription, replication, repairing and splicing.

Abstract
Hematopoiesis in the bone marrow (BM) is maintained by specific interactions between both hematopoietic and non-hematopoietic stromal cells, which are mesenchymal stem cells (MSCs) capable of giving rise to several cell types. The human periodontal ligament (PDL), a tissue of ectomesenchymal origin, has been shown to also be a source of MSCs. We have investigated whether MSCs expanded from the PDL of healthy volunteers express characteristics similar to BM-derived stem cells using structural, immunocytochemical and molecular approaches. Their ability to support the growth of hematopoietic progenitors was also analyzed. The PDL-MSCs exhibited a fibroblast-like morphology and their chromatin was dispersed, indicating active gene transcription. The mesenchymal-related antigens CD90, CD29, CD166, CD105, and CD44 were homogeneously detected by cytofluorimetric analysis, whereas membrane CXCR4 was expressed only by a minority of cells. The PDL-MSCs differentiated in vitro into osteogenic and adipogenic cells. Immunolocalization of IL-7, IL-7Ralpha, SDF-1alpha, and CXCR4 resulted in a diffuse but specific labeling. RT-PCR analysis confirmed the expression of the above-mentioned transcripts. The cells spontaneously produced high levels of IL-7 and SDF-1alpha and were able to support the development and long-term maintenance of BM precursor cells more efficiently than murine stromal cells and similarly to normal BM human stromal cells. We examined IL-7 and SDF-1alpha secretion pathway during adipogenic and osteogenic differentiation. IL-7 increased during osteogenic and adipogenic differentiation, while the SDF-1alpha secretion was downregulated during osteogenic differentiation but increased during adipogenic induction. Our study provides evidence that in human PDL there is an accessible niche of MSCs showing the features of BM-derived MSCs.

Abstract
Apoptosis is an important cell suicide programme involved in physiological and pathological processes. Apoptosis can be induced in different ways depending on cell type and acquired signal. Melatonin, the major secretory product of the pineal gland, participates in many important physiological functions and displays a remarkable functional versatility exhibiting antioxidant, oncostatic, anti-aging, and immunomodulatory properties. Recently, it has been shown that, in addition to pineal gland, human lymphoid cells are an important physiological source of melatonin and that may be involved in the regulation of the immune system. In this work, we examine the effect of melatonin on RAMOS-1 human leukaemic cells. Cell growth and viability, DNA fragmentation and JC-1, and annexin V expression have been determined. To elucidate the mechanism of action of melatonin, Western blot analyses for Bcl-2 and caspase-3 expression, and cytochrome c release were carried out. The results suggest that the apoptotic effect of melatonin is associated with cell-cycle arrest, downregulation of Bcl-2, mitochondrial membrane depolarization, cytochrome c release and activation of caspase-3. The intrinsic (mitochondrial dependent) pathway of caspase activation is the 'point of no return' commitment to cell death. Taken together, our study indicates that melatonin may play a role as potential therapeutic drug in specific lymphoproliferative diseases.

Abstract
Apoptosis is a fundamental process that is required for the normal development and functioning of the immune system. It can be induced in different ways depending on cell type and acquired signal. Since the NF-kappaB transcription factor complex is believed to be involved in nitric oxide-induced apoptosis, the aim of this study was to investigate NF-kappaB and nitric oxide synthase (NOS) activity during dimethyl sulphoxide (DMSO)-dependent cell death of RPMI-8402 human pre-T cells. Our results show that NF-kappaB activation is associated with a significant up-regulation of NOS activity and induction of apoptosis. Furthermore, the inhibition and reversal of these effects by parthenolide treatment or DMSO removal indicate that these molecules are directly involved in the progression of cell death.

Abstract
Oxygen keeps the entire enzymatic machinery in its physiological state. Senescence is associated with damage caused by oxidative stress, affecting also the immune system. In this study the effect of chronic hypoxia for 12 days on young and elderly rat thymus was investigated. The significant changes in cell thymic organization in young and old-aged rat thymus, with redistribution of thymic cells and stroma, were even more marked after prolonged hypoxia. These were further associated to down-regulation of NF-kappaB expression in young rats but up-regulation in old rats. Reorganization of thymic compartments together with disregulated expression of transcription factors, mainly expressed by 'common' thymocytes, may be related to an altered function under hypoxic conditions, inducing opposite responses in young and aged thymuses, probably related to different states of basal oxidative stress.

Abstract
Abstract
The endocytosis of the human CD38 molecule has been investigated in normal lymphocytes and in a number of leukemia- and lymphoma-derived cell lines. CD38 internalization was followed using radioiodinated Abs in an acidic elution endocytosis assay to monitor the effects of cross-linking on internalization processes and to quantify the ratio of the internalized molecule. Second, conventional, confocal, and electron microscopies were used to evaluate the morphologic effects induced by ligation of the molecule with Abs mimicking the natural ligand(s). The results demonstrated that internalization is a reproducible phenomenon following CD38 ligation with both agonistic and nonagonistic specific Abs and involving only a fraction of the entire amount of the surface molecule. It is independent from signal transduction as can be inferred by the observation that 1) both agonistic and non agonistic Abs are effective and 2) the dynamic of internalization is much slower than that of cellular signaling. Morphologic studies demonstrated that endocytosis induced as a result of CD38 ligation presents a very specific pathway consisting of subcellular organelles fundamental to the processing of the complex. Our data indicate that down-regulation by endocytosis may be, in parallel with shedding, a regulatory element in activation and adhesion processes mediated by CD38. However, internalization seems not to be a key step in triggering intracellular signaling; more likely, it is a negative feedback control mechanism which interrupts signal transduction or cell-cell cross-talks mediated by membrane CD38.
