Abstract
Cervical cancer represents one of the most important malignancies among women worldwide. Current therapeutic approaches for cervical cancer are reported not only to be inadequate for metastatic cervical cancer, but are also considered as cytotoxic for several patients leading to serious side effects, which can have negative implications on the quality of life of women. Therefore, there is an urgent need for the development of innovative and effective treatment options. Oncolytic viruses can eventually become effective biological agents, since they preferentially infect and kill cancer cells, while leaving the normal tissue unaffected. Moreover, they are also able to leverage the host immune system response to limit tumor growth. This review aims to systematically describe and discuss the different types of oncolytic viruses generated for targeting cervical cancer cells, as well as the outcome of the combination of virotherapy with conventional therapies. Although many preclinical studies have evaluated the therapeutic efficacy of oncolytic viruses in cervical cancer, the number of clinical trials so far is limited, while their oncolytic properties are currently being tested in clinical trials for the treatment of other malignancies.

Epitope-Specific Anti-SerpinB3 Antibodies for SerpinB3 Recognition and Biological Activity Inhibition. Biomolecules 2023; 13:biom13050739. [PMID: 37238609 DOI: 10.3390/biom13050739] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/21/2023] [Revised: 04/13/2023] [Accepted: 04/21/2023] [Indexed: 05/28/2023] Open
Abstract
SerpinB3 is a serine protease inhibitor that plays a relevant role in disease progression and cancer by increasing fibrosis, cell proliferation, and invasion, besides conferring resistance to apoptosis. The mechanisms underlying these biological activities are not yet fully understood. The aim of this study was to generate antibodies directed against different SerpinB3 epitopes to better investigate their biological role. Five exposed epitopes were identified using the software DNASTAR Lasergene and the corresponding synthetic peptides were used for NZW rabbit immunization. Anti-P#2 and anti-P#4 antibodies were able to recognize both SerpinB3 and SerpinB4 by ELISA. Anti-P#5 antibody, produced against the reactive site loop of SerpinB3, showed the greatest specific reactivity for human SerpinB3. This antibody was able to recognize SerpinB3 at nuclear level, while anti-P#3 antibody recognized SerpinB3 only at cytoplasmic level, both by immunofluorescence and by immunohistochemistry. The biological activity of each antibody preparation was assessed in HepG2 cells overexpressing SerpinB3 and anti-P#5 antibody reduced proliferation by 12% cell and cell invasion by 75%, while trivial results were obtained with the other antibody preparations. These findings indicate that the reactive site loop of SerpinB3 is essential for the invasiveness features induced by this serpin and it could become a novel druggable target.

Abstract
Introduction Cervical cancer is the fourth most common malignancy in women worldwide, and sinonasal inverted papilloma (SIP) is a rare benign sinus tumor with characteristics including a destructive growth pattern, high recurrence rate, and common malignant transformation. Cervical squamous cell carcinoma (SCC) combined with SIP has not been reported thus far. Case Presentation A 55-year-old woman was diagnosed with cervical SCC in our center and treated with concurrent radiochemotherapy. During the follow-up period after the completion of cervical cancer treatment, the progression of cervical squamous cell carcinoma was first considered because the squamous cell carcinoma antigen (SCCA) levels remained high and slowly increased. However, SIP was found after a detailed investigation. The SCCA levels returned to normal after surgery. Two months after the surgery, because SCCA slowly increased again, it was found that the SIP recurred. After additional surgical treatment, the SCCA level returned to normal. Discussion and Conclusion First, SCCA is an important indicator for monitoring changes in cervical SCC. When the changes in SCCA levels are inconsistent with the prognosis of cervical SCC, we should be vigilant about considering the possibility of other diseases existing at other sites in the body, which might lead to the earlier detection and treatment of SIP. Second, We recommended that SCCA be used as a routine monitoring index for SIP. If available, SCCA1 and SCCA2 should be evaluated to provide a more detailed assessment. Finally, for a high recurrence rate of SIP, anti-HPV treatment might be considered to reduce the risk of recurrence.

Abstract
BACKGROUND This study compared the analytical performance of the Elecsys 602 (Roche Diagnostics) system with the I2000 (Abbott laboratories) system for the quantitative measurement of squamous cell carcinoma antigen (SCCA) to assess its role as an indicator in pan squamous cell carcinoma. METHODS 435 serum samples included pan squamous cell cancer group (n = 318) and healthy subjects (n = 52) and non-squamous cell group (n = 41) and benign diseases group (n = 24) were measured by 2 systems and compared. RESULTS The within-run precision coefficient of variation (CV) for Abbott and Roche systems were 3.34-4.88% and 0.95 -1.96%, and the total precision CV were 2.89-9.48% and 3.97-5.38%, respectively. Good correlation was showed in Abbott and Roche systems (slopes = 0.749, r = 0.9658). Serum SCCA in the groups of nasopharyngeal carcinomas, lung squamous cell carcinoma, esophageal squamous cell carcinoma, bladder cancer and cervical squamous cell carcinoma under the curve area (AUC) was more than 0.5, while the AUC in the non- nasopharyngeal carcinomas head and neck squamous cell carcinoma was less than 0.5. The AUC of 2 systems was statistically different in lung squamous cell carcinoma and nasopharyngeal carcinomas (P < 0.05). The levels of SCCA of 2 systems were similarities in esophageal squamous cell carcinoma(stage IV vs. stage 0a-II)and bladder cancer(stage I vs. stage Oa)and cervical squamous cell carcinoma(stage IIB-III vs. stage I-IIA), which advanced stage had higher level of SCCA than early stage. But the SCCA levels of 2 systems were inconsistent in bladder cancer (stage II-IV vs. stage Oa in Abbott), head and neck squamous cell carcinoma (stage IV vs. stage Oa-I in the Roche) and lung squamous cell carcinoma (stage III vs. stage I-II in the Roche). (P < 0.05). CONCLUSIONS 2 systems correlated well in SCCA detection of squamous cell carcinoma, but there were individual differences. Serum SCCA may also contribute to the diagnosis of bladder cancer.

Prognostic Role of Squamous Cell Carcinoma Antigen in Cervical Cancer: A Meta-analysis. DISEASE MARKERS 2019; 2019:6710352. [PMID: 31275450 PMCID: PMC6589214 DOI: 10.1155/2019/6710352] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/14/2018] [Accepted: 03/18/2019] [Indexed: 01/03/2023]
Abstract
Objective To systematically evaluate the significance of squamous cell carcinoma antigen (SCC-Ag) in the prognosis of cervical cancer. Methods Literature from Pubmed, Embase, and Cochrane Library was retrieved to collect all English literature on the correlation between SCC-Ag and cervical cancer prognosis, and the quality of literature collected was assessed based on evaluation criteria. The heterogeneity, sensitivity, and specificity were detected using the StataSE12.0 software, and the correlation between SCC-Ag and cervical cancer prognosis as the effect variables was assessed using the hazard ratio (HR) and 95% confidence interval (CI). Moreover, the forest map and funnel plot were drawn. Results A total of 17 articles meeting the inclusion criteria were selected. The high expression of SCC-Ag was significantly correlated with the poor prognosis of cervical cancer (HR = 2.22, 95% CI = 1.38 − 3.57, P = 0.002). The disease-free survival (DFS) was higher in low SCC-Ag expression patients than in high SCC-Ag expression patients (HR = 2.17, 95% CI = 1.84 − 2.57, P < 0.001). The progression-free survival (PFS) was inferior in patients with a high SCC-Ag expression (HR = 2.70, 95% CI = 1.11 − 6.53, P = 0.028). Conclusion SCC-Ag is an important prognostic factor for cervical cancer, and its high expression is significantly correlated with a poor prognosis of the disease.

Abstract
BACKGROUND Differentiating inverted papilloma from squamous cell carcinoma (SCC) is sometimes difficult. We evaluated the clinical usefulness of serum SCCA1 and SCCA2 in the management of patients with inverted papilloma or SCC. METHODS Serum and tissue samples for the analysis of SCCA1, SCCA2, and SCC antigen were taken from 18 patients with sinonasal inverted papilloma and 23 cases with sinonasal SCC. The SCCA1, SCCA2, and SCC antigen levels were determined. RESULTS The serum SCCA1 concentration was significantly higher in the inverted papilloma group than in the SCC group, whereas the serum SCCA2 level was significantly higher in the SCC group than in the inverted papilloma group. CONCLUSION Patients with sinonasal inverted papilloma predominantly express SCCA1 protein, whereas those with SCC predominantly express SCCA2. This suggests that combined measurements of both serum SCCA1 and SCCA2 concentrations can be very useful for distinguishing sinonasal inverted papilloma from SCC.

Abstract
OBJECTIVE The usefulness of pretreatment measurement of SCC antigen in patients with head and neck SCC is still controversial. Our aim of this study was to evaluate the clinical usefulness of serum SCC antigen, SCCA1 and SCCA2 in the management of patients with head and neck SCC. METHODS Serum samples for the analysis of SCCA1, SCCA2 and SCC antigen were taken from head and neck SCC patients before treatment. Serum SCC antigen was assayed with a solid phase immunoradiometric assay. The SCCA1 and SCCA2 protein level was determined by a sandwich ELISA. RESULTS Fifty-two of 96 cases (54%) showed evaluated serum SCC antigen levels above the upper limit. The serum SCCA2 level was significantly higher in the head and neck SCC patients than in control group, whereas there were no significant differences in the serum SCCA1 level between head and neck SCC patients and control group. 72% of head and neck SCC patients demonstrated SCCA2 levels higher than 0.15, whereas 68% of the control subjects had SCCA2 levels less than 0.15. CONCLUSION The serum SCCA2 levels were increased during the progression of cancer and might be a useful tool for the management of head and neck SCC.

Abstract
Cancer is the second cause of death in 2015, and it has been estimated to surpass heart diseases as the leading cause of death in the next few years. Several mechanisms are involved in cancer pathogenesis. Studies have indicated that proteases are also implicated in tumor growth and progression which is highly dependent on nutrient and oxygen supply. On the other hand, protease inhibitors could be considered as a potent strategy in cancer therapy. On the basis of the type of the key amino acid in the active site of the protease and the mechanism of peptide bond cleavage, proteases can be classified into six groups: cysteine, serine, threonine, glutamic acid, aspartate proteases, as well as matrix metalloproteases. In this review, we focus on the role of different types of proteases and protease inhibitors in cancer pathogenesis.

Abstract
Human SERPINB3 and SERPINB4 are evolutionary duplicated serine/cysteine protease inhibitors. Genomic analysis indicates that these paralogous genes were encoded from independent loci arising from tandem gene duplication. Although the two molecules share 92% identity of their amino acid sequences, they are distinct in the Reactive Center Loop (RCL) including a hinge region and catalytic sequences which accounts for altered substrate specificity. Elevated expression of the two molecules has been reported to contribute to numerous pathological conditions such as inflammatory diseases and cancer. In this review, we focus on summarizing the biochemical features of SERPINB3/B4 and discussing the mechanistic basis for their biological functions and implications in human diseases.

Abstract
Serine protease inhibitors (SERPINs) are involved in a variety of biological processes such as blood clotting, angiogenesis, immune system, and embryogenesis. Although, of these, SERPINB12 is identified as the latest member of clade B in humans, little is known of it in chickens. Thus, in this study, we investigated SERPINB12 expression profiles in various tissues of chickens and focused on effects of steroid hormone regulation of its expression. In the chicken oviduct, SERPINB12 mRNA and protein are abundant in the luminal (LE) and glandular (GE) epithelia of the magnum in response to endogenous or exogenous estrogen. Furthermore, SERPINB12 mRNA and protein increase significantly in GE of cancerous ovaries of laying hens with epithelia-derived ovarian cancer. Collectively, these results indicate that SERPINB12 is a novel estrogen-stimulated gene that is up-regulated by estrogen in epithelial cells of the chicken oviduct and that it is a potential biomarker for early detection of ovarian carcinomas in laying hens and women.

Abstract
The granule-exocytosis pathway is the major mechanism via which cytotoxic lymphocytes eliminate virus-infected and tumor cells. In this pathway, cytotoxic lymphocytes release granules containing the pore-forming protein perforin and a family of serine proteases known as granzymes into the immunological synapse. Pore-formation by perforin facilitates entry of granzymes into the target cell, where they can activate various (death) pathways. Humans express five different granzymes, of which granzymes A and B have been most extensively characterized. However, much less is known about granzyme M (GrM). Recently, structural analysis and advanced proteomics approaches have determined the primary and extended specificity of GrM. GrM functions have expanded over the past few years: not only can GrM efficiently induce cell death in tumor cells, it can also inhibit cytomegalovirus replication in a noncytotoxic manner. Finally, a role for GrM in lipopolysaccharide-induced inflammatory responses has been proposed. In this review, we recapitulate the current status of GrM expression, substrate specificity, functions, and inhibitors.

OBJECTIVES To detect vascular endothelial growth factor (VEGF)-C mRNA expression in surgically resected tissues of 'pathologic N0' (pN0) cervical cancer; to investigate the relevance of VEGF-C mRNA expression to clinicopathological factors, lymph node recurrence and prognosis in early stage cervical cancer. METHODS Patients with pN0 cervical cancer who successfully underwent radical hysterectomy with bilateral adnexectomy and bilateral pelvic lymphadenectomy were enrolled sequentially into this retrospective study. Reverse transcriptase-polymerase chain reaction (RT-PCR) was performed to detect VEGF-C mRNA. RESULTS Seventy-eight patients entered the study. VEGF-C mRNA was detected in 35 (44.87%) patients and was significantly correlated with tumour differentiation. VEGF-C mRNA expression was significantly associated with lymph node recurrence and poor overall survival 5 years after surgery. Multivariate analysis confirmed that VEGF-C mRNA expression was an independent predictor for lymph node recurrence and unfavourable overall survival. CONCLUSIONS These findings indicate that detection of VEGF-C mRNA has clinical potential as a predictor for identifying patients with pN0 cervical cancer at high risk of lymph node recurrence and poor prognosis.

Abstract
BACKGROUND The clinical importance of serum squamous cell carcinoma antigen (SCCA) and SCCA subclasses has not been established for treating inverted papilloma (IP). The aim of this study was to clarify the clinical importance of serum SCCA and its subclasses in IP, compared with maxillary squamous cell carcinoma and inflammatory disease. METHODS Serum SCCA was measured in 22 patients with IP (IP group), 11 with maxillary squamous cell carcinoma (carcinoma group), and 22 with inflammatory disease (inflammatory group). mRNA expression of SCCA subclasses was examined using quantitative real-time polymerase chain reaction. RESULTS In the IP group, 81.8% showed elevated serum SCCA, and 90.3% with recurrent IP showed elevated SCCA. The preoperative SCCA value (mean ± SD, 3.99 ± 4.39) in the IP group was significantly higher than in the carcinoma (1.28 ± 0.88; p = 0.012) and inflammatory (0.60 ± 0.31; p < 0.001) groups. mRNA expression of SCCA1 and SCCA2 in the IP group was higher than in the carcinoma and inflammatory groups. The SCCA2/SCCA1 ratio of mRNA expression (0.11 ± 0.06) in the IP group was similar to that (0.11 ± 0.09) in the inflammatory group, although the ratio (0.20 ± 0.12) in the carcinoma group was significantly higher than in the IP and inflammatory groups. The receiver operating characteristic curve analysis for the SCCA2/SCCA1 ratio to detect carcinoma yielded an area under the curve of 0.760 (95% confidence interval, 0.626-0.894). CONCLUSION The serum level of SCCA is effective for detecting IP, including recurrent IP. In contrast, the SCCA2/SCCA1 ratio is useful for detecting squamous cell carcinoma among other sinonasal diseases.

Abstract
Serine protease inhibitors (SERPINs) appear to be ubiquitously expressed in a variety of species and play important roles in pivotal physiological processes such as angiogenesis, immune responses, blood coagulation and fibronolysis. Of these, squamous cell carcinoma antigen 1 (SCCA1), also known as a SERPINB3, was first identified in squamous cell carcinoma tissue from the cervix of women. However, there is little known about the SERPINB3 expression in human epithelial ovarian cancer (EOC). Therefore, in the present study, we investigated the functional role of SERPINB3 gene in human EOC using chickens, the most relevant animal model. In 136 chickens, EOC was found in 10 (7.4%). SERPINB3 mRNA was induced in cancerous, but not normal ovaries of chickens (P<0.01), and it was abundant only in the glandular epithelium of cancerous ovaries of chickens. Further, several microRNAs, specifically miR-101, miR-1668 and miR-1681 were discovered to influence SERPINB3 expression via its 3′-UTR which suggests that post-transcriptional regulation influences SERPINB3 expression in chickens. SERPINB3 protein was localized predominantly to the glandular epithelium in cancerous ovaries of chickens, and it was abundant in the nucleus of both chicken and human ovarian cancer cell lines. In 109 human patients with EOC, 15 (13.8%), 66 (60.6%) and 28 (25.7%) patients showed weak, moderate and strong expression of SERPINB3 protein, respectively. Strong expression of SERPINB3 protein was a prognostic factor for platinum resistance (adjusted OR; odds ratio, 5.94; 95% Confidence Limits, 1.21–29.15), and for poor progression-free survival (PFS; adjusted HR; hazard ratio, 2.07; 95% CI; confidence interval, 1.03–4.41). Therefore, SERPINB3 may play an important role in ovarian carcinogenesis and be a novel biomarker for predicting platinum resistance and a poor prognosis for survival in patients with EOC.

Abstract
To clarify the synergistic influence of human papillomavirus (HPV) status and squamous cell carcinoma antigen (SCCA) mRNA expression on head and neck squamous cell carcinoma (HNSCC) prognosis, HPV DNA presence and SCCA1 and SCCA2 mRNA expression were determined by PCR and quantitative real-time RT-PCR, respectively, in 121 patients with primary HNSCC who were receiving curative treatment. HPV DNA was detected in 28.1% (34/121) of HNSCC cases, and only high-risk types (HPV-16, HPV-33, HPV-35 and HPV-58) were observed. Positive HPV status showed a significantly better prognosis than negative HPV status (P = 0.022). An elevated SCCA2/SCCA1 mRNA ratio was an independent predictor of disease recurrence (P = 0.004). In addition, HPV-negative patients with a high SCCA2/SCCA1 ratio (>0.27) had a significantly lower recurrence-free survival rate than HPV-negative patients with a low SCCA2/SCCA1 ratio (P < 0.011). Our findings revealed that both HPV status and the SCCA2/SCCA1 mRNA ratio are independently associated with prognosis in HNSCC. Patients with both a HPV-negative status and a high SCCA2/SCCA1 ratio might need intensified treatment and rigorous follow up after treatment because of the high risk of recurrence.

Abstract
AIMS The aim of the study was to evaluate the role of Serpin B3/B4 in advanced idiopathic pulmonary fibrosis (IPF) patients, mainly focusing on epithelial proliferation. METHODS Lungs from 48 IPF patients (including cases with cancer or high-grade epithelial dysplasia) were studied and compared with other diffuse parenchymal diseases and normal lungs. Immunohistochemistry for Serpin B3/B4 and Ki-67 was quantified in all cases, distinguishing stained metaplastic cells. In IPF patients correlations between Serpin expression and several clinicopathological data, including fibrotic remodelling [fibrosis extension and transforming growth factor β expression (TGF-β)] were performed. Molecular analysis was used for Serpin isoform characterisation. RESULTS In IPF patients Serpin B3/B4 and Ki-67 were significantly overexpressed in many metaplastic cells (mainly squamous type) compared to control cases. Higher Serpin B3/B4 was found in older patients and cases with more impaired respiratory function. Serpin B3/B4 expression was related to both TGF-β and Ki-67 and was higher in patients with cancer/high-grade dysplasia. Serpin B3 was expressed in all cases, whereas Serpin B4 was expressed only in IPF. CONCLUSIONS Serpin B3/B4, particularly Serpin B4, appears to play an important role in aberrant epithelial proliferation. Evaluation of Serpin B3/B4 could have prognostic value in predicting disease progression, especially in patients with increased susceptibility to lung cancer.

Abstract
Background Epidemiological studies indicate that a growing number of cirrhotic patients will develop hepatocellular carcinoma (HCC) in the next decade. Recent findings have demonstrated that Squamous cell carcinoma antigen 1 (SCCA1) and 2 (SCCA2) isoforms, now classified as serpinB3 and serpinB4, are over-expressed in HCC, but not in normal liver. As reported, high levels of circulating SCCA-IgM immunocomplexes in patients with cirrhosis are significantly associated with HCC development. Aim To ascertain whether IgM-linked SCCA isoforms circulate in patients with chronic liver disease, compared to total SCCA-IgM levels. Methodology and Findings 79 patients with chronic liver disease were studied, including 17 patients with chronic hepatitis, 36 patients with cirrhosis and 26 with HCC. 28 blood donors were used as control. Monoclonal antibodies against serpinB3 and serpinB4 were used as catcher antibodies to set up specific ELISA assays, while total SCCA-IgM immunocomplexes were detected by commercially available ELISA assay. Overall, the results revealed a better diagnostic sensitivity of total SCCA-IgM assay, compared to both serpinB3 and serpinB4 IgM-linked assays. SerpinB4-IgM median values obtained with SCC103 antibody were moderately higher in patients with cirrhosis than in those with HCC, median values: 0.168 (IQR 0.140–0.427) vs. 0.140 (IQR 0.140–0.278), (p = 0.177). A trend toward decreasing serpinB4-IgM/serpinB3-IgM median ratio was observed in patients with advanced liver disease, being 1.08 in patients with HCC, 1.10 in patients with cirrhosis and 1.40 in patients with chronic hepatitis (p = 0.079). Conclusions IgM-linked SCCA isoforms in serum of patients with chronic liver diseases were quantified for the first time. Although the number of patients was limited, this preliminary study reveals that the relative balance of the two serpin isoforms is altered in HCC and it is characterized by a lower serpinB4-IgM/serpinB3-IgM ratio, determined by lower serpinB4 levels.

Abstract
BACKGROUND The squamous cell carcinoma antigen (SCCA) is widely used as a serological biomarker for various cancers. There are two known SCCA molecules, SCCA1 and SCCA2. We previously found that interleukin-4 or interleukin-13, two related Th2-type cytokines that play an important role in allergic diseases, induce expression of SCCA1 and SCCA2. In this study, we examined whether combined measurements of SCCA1 and SCCA2 are useful for diagnosing atopic dermatitis (AD). METHODS We established new enzyme-linked immunosorbent assays (ELISAs) to specifically detect SCCA1 or SCCA2. We applied serum samples from AD patients with food allergies and from cervical cancer patients to these ELISAs. We performed receiver operating characteristic analyses to diagnose AD and to distinguish AD from cervical cancer. RESULTS Serum concentrations of both SCCA1 and SCCA2 were elevated in AD patients. The serum concentrations of SCCA1 and SCCA2 positively correlated with the clinical severity of AD, showing high specificity (0.86-0.88) and sensitivity (0.86) against control donors. The serum concentrations of SCCA1 and SCCA2 were elevated in cervical cancer patients; however, the SCCA2/SCCA1 ratios clearly distinguished AD patients from cervical cancer patients with high specificity (0.87) and sensitivity (0.87). Expression of SCCA2 was predominant in AD patients, whereas cervical cancer patients showed a predominance of SCCA1. CONCLUSIONS Combined measurements of SCCA1 and SCCA2 are very useful in estimating the severity of allergic diseases, making it possible to distinguish allergic diseases from cancers.

Abstract
Maspin, a member of the serpin family of serine protease inhibitors, was originally identified as a tumor suppressor that is expressed in normal mammary epithelial cells but is reduced or absent in breast carcinomas. Early enthusiasm for maspin as a biomarker for disease progression has been tempered by clinical data that associates maspin with favourable outcomes in some studies and poor prognosis in others. Here, we review all of the published clinical studies for maspin in breast and ovarian cancers and propose that the apparent discordance between clinical reports is a consequence of differential cellular distribution of maspin. Indeed, it was thought that an extracellular pool of maspin possessed tumor suppressor activity, acting by inhibiting migration and increasing cell adhesion. Recent evidence from our group and others indicates, however, that the nuclear localization of maspin in cancer cells is necessary for its tumor suppressor activity. We provide additional data here to demonstrate that nuclear-localized maspin binds to chromatin and is required to effectively prevent cells from metastasizing. Our knowledge of other serpins that localize to the nucleus should help to inform future studies of nuclear maspin. Elucidation of the molecular mechanisms regulating the localization and activities of maspin should pave the way for the development of improved diagnostics and therapies for cancer.

Abstract
Increased numbers of mast cells is a typical feature of a variety of human cancers. The major mediators in the secretory granules of the MC(TC) type of mast cells, serine proteinases tryptase and chymase, may be involved in squamous cell carcinoma (SCC) lesions by inducing matrix remodeling and epithelial cell detachment. The objective of this study was to analyze immunohistochemically whether MC(TC) mast cells as well as protease inhibitors, squamous cell carcinoma antigens (SCCAs), are present in the uterine cervical SCC. In addition, the effect of tryptase and chymase on uterine cervical SCC cell lines was studied in vitro. Here we report that tryptase- and chymase-positive mast cells are present in significant numbers in the peritumoral stroma of SCC lesions. Also, weak SCCA-2 immunoreactivity is observed in the SCC lesions, but only SCCA-1 in uterine cervical specimens with nonspecific inflammation. In cell cultures, especially chymase, but not tryptase, was shown to induce effective detachment of viable, growing and non-apoptotic SiHa SCC cells from substratum. Chymase also detached viable ME-180 SCC cells from substratum as well as degraded fibronectin. In contrast, normal keratinocytes underwent apoptotic cell death after similar prolonged chymase treatment. No inhibition of chymase was detected by SiHa cell sonicates nor did these cells express marked SCCA immunopositivity. MC(TC) mast cells containing tryptase and chymase are present in the peritumoral stroma of uterine cervical SCC and the malignant cells are only weakly immunoreactive for the chymase inhibitor SCCA-2. It is chymase that appears to be capable of inducing effective detachment of viable and growing SCC cells and therefore, it may release SCC cells from a tumor leading to spreading of malignant cells.

Abstract
Squamous cell carcinoma antigen (SCCA) is expressed in normal squamous cell epithelia and in squamous cell carcinomas (SCC). Two nearly identical genes encode the inhibitory serpins SCCA1 (SERPINB3) and SCCA2 (SERPINB4). Serum levels of SCCA are elevated in patients with benign skin diseases and in patients with SCC. SCCA, used for the monitoring of SCC patients, presents no satisfactory diagnostic specificity. As we have shown previously, the reverse transcription polymerase chain reaction (RT-PCR)-based SCCA messenger RNA (mRNA) testing aimed at detecting disseminated cancer cells may be hampered by the false-positive results due to SCCA expression in activated peripheral blood mononuclear cells (PBMC). The aim of this study was to assess the expression of SCCA at mRNA and protein levels in cultured normal PBMC, compared to that in vulvar SCC (VSCC) samples. High SCCA concentrations were found in vulvar tumours and in metastatic lymph nodes, while negative inguinal lymph nodes from the same patients often presented significantly less SCCA. In normal activated PBMC, the level of SCCA protein was the lowest. At the mRNA level SCCA was detectable in normal PBMC even in cultures with no mitogen stimulation, but only by the nested RT-PCR, contrary to VSCC samples found to be SCCA positive already in one-step PCR. Both SCCA1 and SCCA2 transcripts were present in cultured PBMC; SCCA1 was expressed at a higher level than SCCA2. In conclusion, both SCCA forms are detectable in normal PBMC cultured in vitro. SCCA expression level in normal PBMC is much lower than in the squamous epithelium-derived cells. In VSCC, in addition to tumour itself, metastatic lymph nodes seem also to be a potential source of serum SCCA.

Abstract
BACKGROUND Cervical cancer is the second most common malignancy in women, with nearly half a million new cases diagnosed each year worldwide. The authors' recent studies have suggested an association of the cancer testis antigen sperm-associated antigen 9 (SPAG9) in ovarian carcinomas. The aim of the current study was to evaluate the clinical utility of SPAG9 expression and humoral immune response in cervical carcinomas. METHODS SPAG9 mRNA expression was assessed by reverse transcriptase-polymerase chain reaction (RT-PCR) and in situ RNA hybridization. In addition, the authors investigated SPAG9 protein expression by immunohistochemistry and analyzed its association with various stages and grades of cervical cancer patients. They also tested the humoral immune response against SPAG9 in cervical cancer patients. RESULTS RT-PCR, in situ RNA hybridization, and immunohistochemical analyses revealed that SPAG9 expression was significantly associated with tumor grades in 82% of early stage cervical cancer specimens. SPAG9 antibodies were detected in approximately 80% of cervical cancer patients, but not in healthy controls. Statistical analysis revealed that a significant proportion of early stage cancer patients with a high SPAG9 immunoreactivity score (IRS) exhibited significantly higher antibody response against SPAG9 compared with moderate SPAG9 IRSs, suggesting a close relation between SPAG9 protein expression and humoral immune response. CONCLUSIONS The current study findings revealed that in early stage cervical cancer, a substantial number of patients exhibited SPAG9 expression and generated SPAG9 antibodies, supporting its potential role in early detection and diagnosis in cervical cancer management. Furthermore, these findings provide leads for future development of noninvasive serologic biomarkers for the early detection, diagnosis, and treatment of cervical cancer.

Abstract
Cervical cancer is the second most common type of malignant tumor among women worldwide. When the disease is confined locally, it can be controlled with surgical resection and radiotherapy. However, patients with recurrent or metastatic disease often have a poor prognosis. Measurement of serum levels of squamous cell carcinoma (SCC) antigens has been widely used as serological markers for SCC of uterine cervix. Recently, it has been demonstrated that cervical cancer patients with elevated squamous cell carcinoma antigen-2 (SCCA2) expression in tumor cells carry a poor prognosis. Here, by using a luciferase reporter assay, we show that SCCA2 promoter was active in SCCA2-producing human cervical cancer cell lines, including Cx, Cxwj, SiHa and HeLa cells, but relatively quiescent in normal cervical epithelial cells. We then developed a conditionally replicating adenovirus, designated Ad-KFH, under the transcriptional control of the SCCA2 promoter. This E1B-55 kDa-deleted oncolytic adenovirus replicated specifically in and lysed SCCA2-producing cervical cancer cells. Furthermore, in a peritoneal metastatic tumor model, Ad-KFH retarded Cxwj tumor growth in NOD/severe combined immunodeficient mice and prolonged survival of tumor-bearing mice, especially when combined with cisplatin. These results suggest that Ad-KFH may provide a new strategy of gene therapy for advanced or recurrent uterine cervical cancer.
