Abstract
INTRODUCTION Oral squamous cell carcinoma (OSCC) is the most prevalent head and neck cancer. Few studies have analyzed the expression of proteins related to inflammation (COX-2) and tumor progression according to the histological grade of OSCC. OBJECTIVE Analyze the immunohistochemical expression of COX-2, Ki-67 (cell proliferation), Bcl-2/Bax (apoptosis), VEGF, and CD105 (angiogenesis) according to histological grades of OSCC. MATERIAL AND METHODS The immunohistochemical expression of COX-2, Ki-67, Bcl-2, Bax, VEGF, and CD105 of 58 cases of OSCC was analyzed. 13 cases of oral mucosa (OM) were analyzed as controls. RESULTS COX-2, VEGF, CD105, and Ki-67 were higher in OSCC than in OM, particularly in poorly differentiated OSCC (p<0.05). Bax expression was lower in poorly differentiated OSCC (p<0.001). The Bcl-2/Bax ratio was higher in OSCC compared to MO (p<0.05). CONCLUSION There are immunohistochemical differences according to histological grades of OSCC, which could influence clinical behavior.

Abstract
Background & objectives Oral squamous cell carcinoma (OSCC) is widely prevalent in the Indian subcontinent mainly due to habit-associated aetiologies. Immune regulation and angiogenesis are the part of tumourigenesis that play a crucial role in metastasis and survival. However, the concurrent expression of vascular endothelial growth factor (VEGF) and CD3 (immune regulator receptor on T-lymphocyte) in the same OSCC tissue samples has not been reported in the Indian population. The present study evaluated the expression of CD3+ T-cells and VEGF in OSCC tissue samples and studied the clinicopathological correlation and survival analysis in an Indian population. Methods This was a retrospective study conducted on 30 formalin-fixed and paraffin embedded sections which were histologically diagnosed as OSCC cases comprising of 15 metastatic OSCC and 15 non-metastatic OSCC with available clinical data and survival status. Results Reduced expression of CD3+ T-cells and increased VEGF expression were observed in metastatic OSCC samples. The correlation of expression of CD3+ T-cells and VEGF with clinicopathological parameters showed a significant association between these markers with age, nodal status, site of the lesion and survival. Interpretation & conclusions Reduced expression of CD3+ T-cells in OSCC was found to be associated with a significantly poor survival. VEGF was found to be over expressed in metastatic OSCC as compared to that in non-metastatic OSCC. The study findings suggest that the evaluation of CD3 and VEGF in incisional OSCC biopsies can be considered for predicting the survival outcome and metastasis.

Abstract
Background
A group of genetically altered cells that have not transformed into a clinical or histologically identifiable state of malignancy but contains a higher risk of transforming into one is known as the field of cancerization. Numerous molecules are being investigated for their significance in the development of this phenomenon. One such protein of this family is Kaiso also known as ZBTB33 (Zinc Finger and BTB Domain containing 33). This protein belongs to the POZ-ZF family of transcription factors and may have functional tasks similar to its other siblings such as the growth and development of vertebrates and the pathogenesis of neoplastic diseases. Nevertheless, its role in the pathogenesis, progression, epithelial mesenchyal transition and field cancerization in case of oral cancer still needs exploration. Hence, this study was designed to explore the expressional differences between the mucosa of controls and those diagnosed with oral squamous cell carcinoma (OSCC).
Methods
Soft tissue samples were obtained from the main tumor, tumor periphery and opposite buccal mucosa of 50 oral cancer patients, whereas normal mucosa was taken from 50 volunteers undergoing elective tooth removal. The acquired samples were subjected to Immunohistochemical exploration for expression of Kaiso and E-Cadherin. The expression was measured using Image-J IHC profiler and summed as Optical density. The Optical density values were then subjected to statistical analysis.
Results
Results revealed a significant differential expression of Kaiso between the mucosal tissues taken from oral cancer patients and controls (p-value: < 0.0001), showing almost 50% down-regulation of Kaiso in all three tissue samples taken from oral cancer patients as compared to normal mucosa.
Conclusion
Kaiso has a significant difference of expression in the mucosa of oral cancer patients as compared to the mucosa of normal patients, making it a probable contributor to disease pathogenesis and field cancerization.

Abstract
(1) Background: The present study was carried out to evaluate the roles of proliferation and angiogenesis in locally aggressive biologic behavior of ameloblastoma versus ameloblastic fibroma; (2) Methods: 30 formalin-fixed paraffin embedded blocks (15 cases of ameloblastoma and 15 cases of ameloblastic fibroma) were used. To evaluate the proliferation, the tissue sections were stained with an AgNORs stain. CD105 was used as an immunohistochemical marker of angiogenesis. Quantitative evaluations of AgNORs were performed. The mean vascular density was evaluated as a measure for CD105 protein expression by using image analyzer computer system; (3) Results: The mean number of AgNORs dots per nucleus was significantly higher in ameloblastoma as compared to ameloblastic fibroma. Additionally, the protein level of CD105 showed positive expression and wide distribution that the mean vascular density was significantly higher in ameloblastoma as compared to ameloblastic fibroma; (4) Conclusion: Quantitative evaluation of the AgNORs stain and the mean vascular density utilizing CD105 protein expression may reflect a higher proliferative activity and a more locally aggressive biologic behavior of ameloblastoma when compared to ameloblastic fibroma, indicating that other factors may be involved in biologic behavior of ameloblastic fibroma.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Oral cancers are found to have high risk in South Central Asia due to exposure of various risk factors. Euphoria longana Lam. (EL) has been traditionally used to relieve insomnia, prevent amnesia, and treat palpitation. In addition, EL has been reported to have anti-inflammatory, anti-cancer, and antioxidant activities. The investigation was aimed to evaluate the mechanism of action and antitumor activity of polyphenol-rich EL seeds extract against oral cancer induced by 4-Nitroquinoline-1-oxide (4-NQO). MATERIALS AND METHODS Seven groups of Sprague-Dawley rats were formulated: normal animals, oral cancer induced with 4-NQO, EL-treated normal control, EL-treated disease control from 0-day, EL-treated disease control from 60 days, 5-fluorouracil (5-FU)-treated disease control from day 60, and combined EL- and 5-FU-treated disease control animals from day 60. The animal tongue was smeared with 0.5% 4-NQO at frequency of thrice a week for 12 weeks to induce oral cancer. At the end of treatment, excised tongues were used for biochemical and tumour-specific parameters along with histopathology assessment. RESULTS Treatment with EL, 5-FU, and combination of both in diseased animals exhibited significant improvement in interleukin-6, vascular endothelial growth factor (VEGF), and Transforming growth factor beta (TGF-β) levels, antioxidant status together with histoarchitecture of the tongue tissue. In addition, the combination of both was slightly more effective than EL and 5-FU alone. CONCLUSION Our data suggest antitumor activity of Euphoria longana Lam. Extract against 4-NQO induced oral cancer in rats, which could be attributed to alteration in the VEGF and TGF-β signaling axis.

Abstract
The pathogenesis of oral cancer is a complex and multifactorial process that requires a deep understanding of the underlying mechanisms involved in the development and progress of malignancy. The ever-improving comprehension of the diverse molecular characteristics of cancer, the genetic and epigenetic alterations of tumor cells, and the complex signaling pathways that are activated and frequently cross talk open up promising horizons for the discovery and application of diagnostic molecular markers and set the basis for an era of individualized management of the molecular defects underlying and governing oral premalignancy and cancer. The purpose of this article is to review the key molecular concepts that are implicated in oral carcinogenesis, especially focusing on oral squamous cell carcinoma, and to review selected biomarkers that play a substantial role in controlling the so-called "hallmarks of cancer," with special reference to recent advances that shed light on their deregulation during the different steps of oral cancer development and progression.

Abstract
OBJECTIVE The aim of this study was to compare and correlate mast cell density (MCD) and microvessel density (MVD) between normal oral mucosa, oral lichen planus, various grades of dysplasia, and oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS The study comprised a total of 75 samples, of which 65 were archival tissue blocks of histopathologically confirmed cases, which included 10 cases of oral lichen planus, 25 cases of dysplasia (mild [n=10], moderate [n=10], and severe [n=5]), and 30 cases of OSCC (well differentiated [n=10], moderately differentiated [n=10], and poorly differentiated [n=10]), and 10 samples of normal oral mucosa. All the sections were immunohistochemically stained with anti-CD34 and counterstained with toluidine blue stain. Mean MCD and MVD were determined and analyzed using ANOVA test and compared between the lesions using Tukey HSD test. Pearson's correlation coefficient test was used to correlate these two factors between various lesions. RESULTS Mean MCD and mean MVD were found to be increased in all the lesions compared to normal oral mucosa, and the values were statically significant. Overall, MCD and MVD showed a significant positive correlation (r=0.640). CONCLUSION Increase of MCD and MVD and their positive correlation in all the lesions have emphasized their role in the pathogenesis and disease progression.

Cigarette smoke modulates binding of the transcription factor MZF1 to the VEGF promoter and regulates VEGF expression in dependence of genetic variation SNP 405. J Oral Pathol Med 2020; 49:780-786.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) affects carcinogenesis of the upper aerodigestive tract. Cigarette smoke (CSE) influences VEGF-gene regulation. The single nucleotide polymorphism +405 G/C (SNP +405 G/C) and the transcriptional factor (TF) myeloid zinc finger 1 (MZF1) are endogenic regulators of the VEGFpromoter as the polymorphism 405 potentially affects binding of the transcription factor MZF1. Therefore, this in vitro study analysed cancer cells of the upper aerodigestive tract after CSE incubation concerning MZF1-binding specificity and VEGF expression in dependency of VEGF polymorphism +405 G/C compared to wild type (wt). METHODS In human alveolar epithelial-like type-II cells (A549) and oral squamous cell cancer cells (HNSCCUM-02T) SNP +405 G/C- and MZF1-dependent VEGF promoter activity and VEGF expression were analysed by qRT-PCR and Western blot after incubation with 10% CSE. Temporary knock-down of MZF1 was performed using siRNA. MZF1 binding was analysed by Co-Chromatin-Immunoprecipitation (Co-ChiP) (each test n = 3). RESULTS We found a stronger MZF1 binding to VEGF polymorphism 405 in A549 cells (P < .05) compared to HNSCCUM-02T cells (P = .02), where MZF1 binding was reduced. MZF1 knock out reduced VEGF promoter activity in HNSCCUM-02T cells, showing the relevance of the factor for transcriptional activation of the VEGF promoter. Finally, we found that CSE increases promoter activity in both cell lines and no significant differences between the two analysed polymorphisms concerning their activating capacity. CONCLUSION In summary, both VEGF promoter polymorphisms are similar effective in terms of transcriptional activity, and MZF1 is a transcriptional activator of VEGF promoter. Moreover, cigarette smoke increases MZF1 binding of VEGF-promoter and directly affects VEGF-gene regulation.

Abstract
BACKGROUND Significant increase in cell proliferation and vascularity occurs during the transition from normal oral mucosa through differing degrees of dysplasia to oral squamous cell carcinoma (OSCC). AIMS To evaluate the cell proliferation and vascularity in potentially malignant disorders and OSCC. SETTINGS AND DESIGN Proliferating cell nuclear antigen (PCNA), vascular endothelial growth factor (VEGF) and CD34 were quantified immunohistochemically (IHC) using anti-PCNA, anti-VEGF and anti-CD34 antibody. MATERIALS AND METHODS A total of 60 archival specimens included 10 oral lichen planus, 10 oral leukoplakia, 10 oral submucous fibrosis and 30 OSCC (well differentiated, moderately differentiated and poorly differentiated), and also, 10 normal oral mucosa as control group were taken. PCNA, VEGF and CD34 expression was assessed in relation to the localization and area of IHC-stained cells. STATISTICAL ANALYSIS One-way analysis of variance test and post hoc least significant difference test were assessed for statistical significance. RESULTS Cell proliferation and vascularity appeared to increase gradually with disease progression. CONCLUSION Upregulation of cell proliferation and vascularity indicates their possible role in malignant transformation of potentially malignant disorders.

Abstract
Two daughters in a Chinese consanguineous family were diagnosed as diffuse pulmonary arteriovenous malformations (PAVMs) and screened using whole exome sequencing (WES) and copy number variations (CNVs) chips. Though no mutation was found in the established causative genes of capillary malformation-AVMs (CM-AVMs) or PAVMs, Ser161Ile (hg19 NM_022493 c.482G>T) mutation in nuclear prelamin A recognition factor-like (NARFL) was identified. Ser161Ile mutation in NARFL conservation region was predicted to be deleterious and absent in 500 population controls and Exome Aggregation Consortium (ExAC) Database. And there was a dosage effect of the mutation on mRNA levels among family members and population controls, consistent with the instability of mutant mRNA in vitro. Accordingly, in lung tissue of the proband, NARFL protein expression was reduced but Fe3+ was overloaded with vascular endothelial growth factor (VEGF) overexpression. Furthermore, NARFL-knockdown cell lines demonstrated decreased activity of cytosolic aconitase, while NARFL-knockout zebrafish presented ectopic subintestinal vessels sprouts and upregulated VEGF. So we concluded that the Ser161Ile mutant induced NARFL deficiency and eventually diffuse PAVMs probably through VEGF pathway. In a word, we detected a functional mutation in NARFL, which might be the pathogenic gene in this pedigree.

Abstract
OBJECTIVE Oral squamous cell carcinoma (OSCC) invades and metastasizes, by degrading the extracellular matrix (ECM) and is associated with poor prognosis. Matrix-metalloproteinase (MMP-9) can initiate ECM degradation and angiogenesis which brings a significant change in tumor microenvironment favoring tumor progression. A major thrust has been laid on understanding this key enzyme as it has significant implications for cancer therapy. Comprehending the association of vasculature with MMP-9 expression in precancerous lesions oral epithelial dysplasia (OED) and OSCC is essential since the data regarding the same are fewer. The aim is to evaluate and correlate MMP-9 expression with morphometric analysis of mucosal vasculature in the normal oral mucosa (NOM), OED, and OSCC. METHODS A total of 60 histologically diagnosed cases of OED (n = 30); OSCC (n = 30); along with 10 NOM (n = 10) as control were included. Immunohistochemical staining of MMP-9 and vascular morphometric analysis was performed for all the cases. Results were analyzed using the Chi-square test, Fischer exact test, and Spearman correlation test. RESULTS A statistically significant difference in MMP-9 was noted among the groups with P = 0.011* (epithelium); P = 0.001* (stroma) by the highest value in OSCC group. Morphometry also revealed a progressive increase from NOM to OED to OSCC. Spearman's correlation of MMP-9 with vascular parameters illustrated a positive relation of MMP-9 with mean vascular density (MVD) and mean vascular area percentage (MVAP). CONCLUSION Positive correlation of MMP-9 with MVD and MVAP demonstrates this markers effect on angiogenesis. Henceforth, MMP-9 can be embattled as a potential therapeutic target in combating tumor progression.

Abstract
BACKGROUND Actinic cheilitis is a potentially malignant condition caused mainly by chronic sun exposure. Here we aim to evaluate the role of hypoxia, angiogenesis, and lymphatic density in the clinical and morphological progression of a series of cases of actinic cheilitis. MATERIALS AND METHODS Immunohistochemistry was used to evaluate positivity to hypoxia-inducible factor (HIF)-1α, vascular endothelial growth factor (VEGF)-C, and D2-40 in 40 cases of actinic cheilitis of the lower lip. RESULTS The cases studied exhibited variable degrees of positivity to the markers. The median number of lymphatic vessels was 3.2, 2.4, and 3.0 in lesions showing no epithelial dysplasia (NED) and with mild (MED) and moderate (MOED) epithelial dysplasia, respectively. The median VEGF-C positivity index was 82.44% (NED), 92.74% (MED), and 82.83% (MOED), and the median HIF-1α positivity index was 11.57% (NED), 5.26% (MED), and 13.55% (MOED). No significant differences in lymphatic density or median VEGF-C and HIF-1α positivity indices were observed between histological grades or clinical presentations of actinic cheilitis (P > 0.05). CONCLUSIONS Although representing early events in lip carcinogenesis, the present results suggest that hypoxia, angiogenesis, and lymphangiogenesis do not influence the morphological or clinical progression of actinic cheilitis.

Abstract
OBJECTIVES/HYPOTHESIS This study investigates the immunohistochemical expression of vascular endothelial growth factor (VEGF) and CD34 in patients treated for middle ear and mastoid cholesterol granulomas to evaluate the angiogenesis and vascularization of this type of lesion. A correlation between the immunohistochemical data and the radiological and intraoperative evidence of temporal bone marrow invasion and blood source connection was performed to validate this hypothesis. STUDY DESIGN Retrospective study. METHODS Immunohistochemical expression of VEGF and CD34 in a group of 16 patients surgically treated for cholesterol granuloma was examined. Middle ear cholesteatomas with normal middle ear mucosa and external auditory canal skin were used as the control groups. The radiological and intraoperative features of cholesterol granulomas were also examined. RESULTS In endothelial cells, there was an increased expression of angiogenetic growth factor receptors in all the cholesterol granulomas in this study. The quantitative analysis of VEGF showed a mean value of 37.5, whereas the CD34 quantitative analysis gave a mean value of 6.8. Seven patients presented radiological or intraoperative evidence of bone marrow invasion, hematopoietic potentialities, or blood source connections that might support the bleeding theory. In all of these cases there was computed tomography or intraoperative evidence of bone erosion of the middle ear and/or temporal bone structures. The mean values of VEGF and CD34 were 41.1 and 7.7, respectively. CONCLUSIONS High values of VEGF and CD34 are present in patients with cholesterol granulomas. Upregulation of VEGF and CD34 is indicative of a remarkable angiogenesis and a widespread vascular concentration in cholesterol granulomas. LEVEL OF EVIDENCE 3b. Laryngoscope, 127:E283-E290, 2017.

Abstract
Oral Cancer (OC) is a subset of head and neck cancer (HNC) with an annual worldwide incidence of 275,000 cases. OC remains a significant burden worldwide in terms of diagnosis, treatment and prognosis. Despite desirable outcomes in early diagnosed OCs and treatment advances most OCs are detected in advanced stages. The 5-year survival rate of early-stage disease is ∼80% and that of late-stage disease is only ∼20%. Recurrence and chemoresistance from a treatment point of view and pain and disfiguration are important factors contributing to the high morbidity and mortality of OC. Furthermore the process of oral carcinogenesis is complex and not yet fully understood. Consequently numerous potential biomarkers have been hypothesised though controversial results across the board hamper their clinical implementation. Of greatest advantage would be biomarkers signalling early events preceeding OC. Biomarker targets predominately involve deregulated molecular events that participate in cell signalling, growth, survival, motility, angiogenesis and cell cycle control but can also use changes in metabolic genes to discriminate healthy form disease state. Promising potential biomarkers include the growth signalling oncogenes, Epidermal Growth Factor Receptor and Cyclin D1, the anti-growth signalling components p53 and p21, apoptotic effectors such as Bcl-2 and also components involved in immortalisation, angiogenesis, invasion and metastasis processes. Translation of these potential biomakers to the patients is closer than ever though few issues remain to be resolved. Firstly large clinical trials are needed to validate their clinical applicability but also standardised methods of collection, storage and processing methods are needed to minimise variability.

Abstract
BACKGROUND New blood vessels formation is a critical step in tumor progression. Vascular density affects the clinical outcome and prognosis of malignant tumors. The aim of this study was to investigate the relation between the Vascular Endothelial Growth Factor (VEGF) expression and vascular density with the clinical and histopathologic features in oral squamous cell carcinoma (OSCC). METHODS In this retrospective study, 22 paraffin embedded block of well-differentiated OSCC were examined immunohistochemically for VEGF expression. Vascular density was determined by counting the blood vessels in 6 fields with 100 (HPF) on hematoxylin-eosin stained slides. The relation between the VEGF expression and vascular density with clinical and histopathologic features were analyzed by t-test, ANOVA, and Chi-square tests. RESULTS A significant relation between gender (P=0.06) and tumor size (p=0.05) with vascular density was obtained. The relation between VEGF expression and gender (p=0.41), age (p=0.35), lymph node involvement (p=0.38), tumor size (p=0.15) and tumor differentiation (p=0.34) was not significant. The relation between vascular density and age (p=0.55), lymph node involvement (p=0.20), and tumor differentiation (p=0.80) was not significant. CONCLUSION Blood vessels formation relates to tumor size. Controlling the tumor size by manipulating the blood vessels formation may contribute to the inhibition of tumor progression in malignant tumors.

Abstract
We report three-dimensional (3D) imaging of microcirculation within human cavity tissues in vivo using a high-speed swept-source optical coherence tomography (SS-OCT) at 1300 nm with a modified probe interface. Volumetric structural OCT images of the inner tissues of oral and nasal cavities are acquired with a field of view of 2 mm × 2 mm. Two types of disposable and detachable probe attachments are devised and applied to the port of the imaging probe of OCT system, enabling forward and side imaging scans for selective and easy access to specific cavity tissue sites. Blood perfusion is mapped with OCT-based microangiography from 3D structural OCT images, in which a novel vessel extraction algorithm is used to decouple dynamic light scattering signals, due to moving blood cells, from the background scattering signals due to static tissue elements. Characteristic tissue anatomy and microvessel architectures of various cavity tissue regions of a healthy human volunteer are identified with the 3D OCT images and the corresponding 3D vascular perfusion maps at a level approaching capillary resolution. The initial finding suggests that the proposed method may be engineered into a promising tool for evaluating and monitoring tissue microcirculation and its alteration within a wide-range of cavity tissues in the patients with various pathological conditions.

Abstract
There always exists a field with genetically altered cells with a high risk of developing premalignant and malignant lesions. It may often happen that an individual stem cell is genetically altered and can cause the formation of a clone or a patch which is likely to turn into a tumor. This explains the higher recurrence rates following tumor resections. It is essential to identify and to treat this field in order to have greater chances to prevent cancer and achieve a better outcome. This article reports concepts, theories and markers for the assessment of field cancerization.

Abstract
Tissue vasculature is altered when cancer develops. Consequently, noninvasive methods of monitoring blood vessel size, density, and oxygenation would be valuable. Simple spectroscopy employing fiber optic probes to measure backscattering can potentially determine hemoglobin parameters. However, heterogeneity of blood distribution, the dependence of the tissue-volume-sampled on scattering and absorption, and the potential compression of tissue all hinder the accurate determination of hemoglobin parameters. We address each of these issues. A simple derivation of a correction factor for the absorption coefficient, μa, is presented. This correction factor depends not only on the vessel size, as others have shown, but also on the density of blood vessels. Monte Carlo simulations were used to determine the dependence of an effective pathlength of light through tissue which is parameterized as a ninth-order polynomial function of μa. The hemoglobin bands of backscattering spectra of cervical tissue are fit using these expressions to obtain effective blood vessel size and density, tissue hemoglobin concentration, and oxygenation. Hemoglobin concentration and vessel density were found to depend on the pressure applied during in vivo acquisition of the spectra. It is also shown that determined vessel size depends on the blood hemoglobin concentration used.

Abstract
Background: Angiogenesis is the formation of new vessels from preexisting ones which takes place by capillary sprouting. It is seen in healing, at sites of injury and collateral circulation in ischemia. It is also seen in tumors, as once the original blood supply of a tumor is exhausted it cannot grow without further blood supply. Also as the angiogenic capacity of a tumor increases, its microvasculature, that is, microvessel density (MVD) also increases. Based on this literary evidence we carried out an immunohistochemical (IHC) study to observe the relationship between the expression of vascular endothelial growth factor (VEGF) [angiogenesis] and CD 34 [MVD] in oral squamous cell carcinoma (OSCC). Aim: To evaluate the correlation between expression of VEGF and CD 34, the role of MVD in progression of OSCC and to compare the degree of angiogenesis in different grades of OSCC. Settings and Design: In this study we observed the relation between angiogenesis and MVD and the overall effect of this on oral cancer. Materials and Methods: Thirty-three cases of OSCC were stained with hematoxylin and eosin, (H and E) to confirm the diagnosis and immunohistochemically using VEGF and CD 34 antibody. The slides were evaluated for positivity and intensity of staining. Statistical Analysis: The result was subjected to statistical analysis using analysis of variance (ANOVA) test and Fisher's exact test. Results: VEGF positivity as well as MVD was found to be independent of the grade of the tumor. Tumor MVD was found to be independent of expression of VEGF.

Abstract
PURPOSE Although meshes reduce abdominal hernia recurrence, they increase the risk of inflammatory complications. This study aimed to compare the early and late postoperative inflammation and collagen deposition responses induced by three meshes. METHODS Rats were allocated into three groups. In group I, a polypropylene (PP) mesh was implanted in the abdominal wall. In groups II and III, PP + polyglactin (PP + PG) and PP + titanium (PP + TI) meshes were employed, respectively. On the seventh (7th) postoperative day, collagen deposition and inflammation were evaluated, and immunohistochemistry was performed on abdominal wall biopsies. These data were compared with those obtained on the fortieth (40th) postoperative day in a previous study. RESULTS The early inflammatory responses were the same in all groups. With time, it decreased in group I (p = 0.047) and increased in group II (p = 0.003). Group I exhibited early elevated VEGF (p < 0.001), COX2 (p < 0.001), and collagen (p = 0.023) levels, and group II exhibited the most severe inflammatory tissue response. On the 40th postoperative day, the VEGF (p < 0.001) and collagen (p < 0.005) were reduced as compared with the 7th postoperative day in all groups. CONCLUSIONS Belatedly, the inflammatory reaction decreased in PP mesh group and increased in PP + PG mesh group. The PP mesh induced early great elevations in VEGF, COX2 and collagen levels, whereas the PP + PG mesh caused severe tissue inflammation with small elevation in these levels. PP + TI mesh induced inflammatory response levels between the others. In conclusion, the inflammatory response depends on the mesh density and also the mesh material with clinical implications.

Abstract
OBJECTIVE The aim of this study was to investigate the mechanism by which phosphatase of regenerating liver-3 (PRL-3) induces angiogenesis in endometrial adenocarcinoma tissues and cells. METHODS We investigated the expression of PRL-3 and vascular endothelial growth factor (VEGF) in samples from 124 patients with endometrial adenocarcinoma using immunohistochemical staining. The relationship between PRL-3 expression and microvessel density (MVD), clinicopathological factors and surgical treatment outcome was also studied. Following this, we studied the effect on cell lines of blocking or upregulating PRL-3. RESULTS PRL-3 expression in endometrial adenocarcinoma was high, and this overexpression is correlated with advanced clinical stage (p=0.008), lymph node metastasis (p=0.016) and poor postoperative survival. PRL-3 overexpression was associated with VEGF (p=0.001) expression and MVD (p=0.005). Upregulating PRL-3 expression promoted VEGF and phosphorylated extracellular signal-regulated kinase (pERK) expression. Blocking PRL-3 expression inhibited VEGF and pERK expression. Following inhibition of pERK, VEGF expression was downregulated. CONCLUSIONS PRL-3 induces microvascular vessel formation by facilitating VEGF expression in endometrial adenocarcinoma tissues. PRL-3 upregulates pERK expression and activity, facilitating VEGF expression and accelerating angiogenesis.

Abstract
Background Oral squamous cell carcinoma is an important cause of death and morbidity wordwide and effective prognostic markers are still to be discovered. HIF1α protein is associated with hypoxia response and neovascularization, essential conditions for solid tumors survival. The relationship between HIF1α expression, tumor progression and treatment response in head and neck cancer is still poorly understood. Patients and Methods In this study, we investigated HIF1α expression by immunohistochemistry in tissue microarrays and its relationship with clinical findings, histopathological results and survival of 66 patients with squamous cell carcinoma of the lower mouth. Results Our results demonstrated that high HIF1α expression is associated with local disease-free survival, independently from the choice of treatment. Furthermore, high expression of HIF1α in patients treated with postoperative radiotherapy was associated with survival, therefore being a novel prognostic marker in squamous cell carcinoma of the mouth. Additionally, our results showed that MVD was associated with HIF1α expression and local disease relapse. Conclusion These findings suggest that HIF1α expression can be used as a prognostic marker and predictor of postoperative radiotherapy response, helping the oncologist choose the best treatment for each patient.
