Garlic ( Allium sativum L.) Bioactives and Its Role in Alleviating Oral Pathologies. Antioxidants (Basel) 2021; 10:antiox10111847. [PMID: 34829718 PMCID: PMC8614839 DOI: 10.3390/antiox10111847] [Citation(s) in RCA: 21] [Impact Index Per Article: 7.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 11/10/2021] [Accepted: 11/16/2021] [Indexed: 02/07/2023] Open
Abstract
Garlic (Allium sativa L.) is a bulbous flowering plant belongs to the family of Amaryllidaceae and is a predominant horticultural crop originating from central Asia. Garlic and its products are chiefly used for culinary and therapeutic purposes in many countries. Bulbs of raw garlic have been investigated for their role in oral health, which are ascribed to a myriad of biologically active compounds such as alliin, allicin, methiin, S-allylcysteine (SAC), diallyl sulfide (DAS), S-ally-mercapto cysteine (SAMC), diallyl disulphide (DADS), diallyl trisulfide (DATS) and methyl allyl disulphide. A systematic review was conducted following the PRISMA statement. Scopus, PubMed, Clinicaltrials.gov, and Science direct databases were searched between 12 April 2021 to 4 September 2021. A total of 148 studies were included and the qualitative synthesis phytochemical profile of GE, biological activities, therapeutic applications of garlic extract (GE) in oral health care system, and its mechanism of action in curing various oral pathologies have been discussed. Furthermore, the safety of incorporation of GE as food supplements is also critically discussed. To conclude, GE could conceivably make a treatment recourse for patients suffering from diverse oral diseases.

Abstract
Lip, oral cavity, and pharyngeal cancers (LOCP) constitute a group of rare neoplasms with unfavorable prognosis. So far, not much is known about the role of vitamin D and oxidative stress in the pathogenesis of LOCP in the European population. The aim of the study was to determine the concentrations of vitamin D, osteopontin, melatonin, and malondialdehyde (MDA) as markers of oxidative stress and/or inflammation, as well as the activities of antioxidant enzymes in the course of LOCP. The vitamin D, melatonin, and osteopontin concentrations in blood serum, the MDA levels in erythrocytes and blood plasma, and the activities of superoxide dismutase (SOD-1), catalase (CAT), and glutathione peroxidase (GPx) in erythrocytes were measured in blood samples taken from 25 LOCP patients of middle age (YCG), 20 LOCP elderly patients (OCG), and 25 healthy middle-aged volunteers. In both cancer groups, decreases in vitamin D and CAT, as well as increases in osteopontin and blood plasma MDA, were observed. An increase in GPx activity in YCG and a decrease in melatonin level in OCG were found. The results indicate the vitamin D deficiency and disturbed oxidant-antioxidant homeostasis in LOCP patients. Osteopontin seems to be associated with LOCP carcinogenesis and requires further research.

Abstract
Background Oral squamous cell carcinoma (OSCC) is the most common malignant neoplasm of the oral cavity. Osteopontin (OPN) has been proved as a biomarker in varying malignant tumors. Only limited studies detail the role of OPN in OSCC. Aims This study aims to demonstrate the expression of OPN in OSCC and to correlate the expression of OPN with the histologic grades of OSCC. Settings and Design This is a retrospective immunohistochemical study in Dravidian population (linguistically Malayalam). Materials and Methods Thirty diagnosed cases of OSCC were subjected to immunohistochemistry using OPN antibody for detection of OPN expression. Ten normal oral mucosal specimens were also stained as controls. Statistical Analysis Used Chi-square test and ANOVA followed by Bonferroni test. Results OPN expression was significantly higher in OSCC patients than in controls. In normal oral mucosal specimens, none of them showed OPN immunoreactivity. A significant difference was observed between total scores and intensities of normal and varying grades of OSCC. A significant difference was also observed between the percentage of positive cells for OPN expression of normal and varying grades of OSCC. However, no significant difference was observed between the percentage of positive cells for OPN expression of well-, moderate-, poorly-differentiated carcinomas. Correlation of OPN expression with lymph node status, site, and sex was found to be statistically insignificant. Conclusion Insights gained from this study may lead to research targeted at the treatment of OSCC.

Abstract
Complex interactions between tumor and host cells regulate systemic tumor dissemination, a process that begins early at the primary tumor site and goes on until tumor cells detach themselves from the tumor mass and start migrating into the blood or lymphatic vessels. Metastatic cells colonize the target organs and are capable of surviving and growing at distant sites. In this context, osteopontin (OPN) appears to be a key determinant of the crosstalk between cancer cells and the host microenvironment, which in turn modulates immune evasion. OPN is overexpressed in several human carcinomas and has been implicated in inflammation, tumor progression, and metastasis. Thus, it represents one of the most attracting targets for cancer therapy. Within the tumor mass, OPN is secreted in various forms either by the tumor itself or by stroma cells, and it can exert either pro- or antitumorigenic effects according to the cell type and tumor microenvironment. Thus, targeting OPN for therapeutic purposes needs to take into account the heterogeneous functions of the multiple OPN forms with regard to cancer formation and progression. In this review, we will describe the role of systemic, tumor-derived, and stroma-derived OPN, highlighting its pivotal role at the crossroads of inflammation and tumor progression.

Abstract
Background: Early detection of oral squamous cell carcinoma (OSCC) remains one of the most efficient ways to ensure patient survival and improved quality of life. Although specific biomarkers related to OSCC have been investigated, a useful biomarker that assesses the transition potential of potentially malignant lesion to OSCC remains to be found. Osteopontin (OPN) has been recognized as an important factor in tumorigenesis and their expression in OSCC have been investigated earlier. In the present study, evaluation of OPN expression in premalignant and malignant lesions has been carried out to assess their possible role as a biomarker in the early diagnosis and prognosis of OSCC. Objectives: The objective of this study is to evaluate the role of OPN as a biomarker in the diagnosis and prognosis of OSCC. Materials and Methods: The study group consisted of archival paraffin-embedded blocks of ten cases each of varying grades of OSCC, oral epithelial dysplasias and epithelial hyperplasias. Sections were subjected to immunohistochemical staining for the biomarker OPN. Results: A positive OPN expression was noticed in epithelial dysplasias and SCC arising from the oral epithelium. A progressive increase in the intensity of staining was seen with increasing grades of dysplasias and a decrease in OPN expression with an increase in grades was observed in OSCC. Conclusion: The expression of OPN in full thickness of epithelium in severe dysplasias, carcinoma in situ, and in the superficial epithelium of OSCC suggest the possibility of considering OPN expression in full epithelial thickness in dysplasias as an indicator for malignant transformation.

Abstract
Extracellular matrix is composed of a complex array of molecules that together provide structural and functional support to cells. These properties are mainly mediated by the activity of collagenous and elastic fibers, proteoglycans, and proteins such as fibronectin and laminin. ECM composition is tissue-specific and could include matricellular proteins whose primary role is to modulate cell-matrix interactions. In adults, matricellular proteins are primarily expressed during injury, inflammation and disease. Particularly, they are closely associated with the progression and prognosis of cardiovascular and fibrotic diseases, and cancer. This review aims to provide an overview of the potential use of matricellular proteins in drug delivery including the generation of therapeutic agents based on the properties and structures of these proteins as well as their utility as biomarkers for specific diseases.

Abstract
Aim: This study aimed to correlate the prognostic value of osteopontin (OPN) expression using both tissue and plasma samples from patients with clinically and histologically confirmed oral squamous cell carcinoma (OSCC). Methods and Materials: The study group comprised of sixty patients (n = 60), which were clinically and histologically diagnosed for oral squamous cell carcinoma (OSCC). The Control group comprised of ten (n = 10) healthy volunteers. Plasma OPN levels were assayed using a quantitative enzyme-linked immunosorbent assay (OPN ELISA). Expression of OPN was also identified and evaluated by immunohistochemistry in tissue sections. These OPN expressions were then correlated with different parameters like age, sex, site, clinical presentation, tumor node metastasis (TNM) staging, histopathological grading and lymph node metastasis. Statistical Analysis: One-way analysis of variance (ANOVA) was used to evaluate the difference in tissue intensity and plasma OPN levels between the OSCC and the normal control groups. Results: The distribution of the plasma OPN levels and tissue OPN intensity in OSCC cohorts were compared to histopathological grades and analyzed. When evaluated OPN expression in tissue had higher intensity observed in OSCC (95% +ve) cases. And the mean plasma OPN concentration in OSCC cohort was more in comparison to the normal cohort. The results clearly showed that the plasma OPN levels and intensity grading in tissue correlated with tumor grades. Conclusion: The study highlights OPN as a biomarker for prognosis in OSCC in both plasma and tissue samples. We would like to emphasize on the evaluation of plasma OPN as a protocol of blood examination for all cancer patient, as it may serve as an indicator for tumor progression and potential risk of metastasis.

Abstract
INTRODUCTION Osteopontin (OPN) is non-collagenous extracellular matrix protein involved in various physiological and pathological events, including tumor progression. The aim of this study was to analyze the expression of OPN in normal oral mucosa and oral squamous cell carcinoma (OSCC) and to assess its prognostic significance. METHODS The expression of OPN was immunohistochemicaly analyzed in 86 OSCC and compared with clinicopathological variable such as tumor size, nodal stage, WHO clinical stage, Ki-67 proliferation index, and patients' outcome. OPN mRNA was analyzed using quantitative real-time PCR and compared with protein OPN expression and clinical outcome in 18 OSCC samples. RESULTS The expression of OPN protein was found in OSCC tumor cells (t-OPN) and various stromal cells (s-OPN). High level of t-OPN expression was associated with higher nodal stage (P = 0.045), higher WHO clinical stage (P = 0.033), and poor clinical outcome (P = 0.022). In multivariate analysis, t-OPN emerged as an adverse independent factor for survival (P = 0.049). Although correlated with t-OPN (P = 0.005), s-OPN was not significantly associated with clinical parameters, including patients' outcome. Also, there was no association between OPN and clinical parameters at the mRNA level. CONCLUSION OPN is upregulated in tumor and stromal OSCC cells. Tumor cell-derived OPN is involved in tumor progression and can independently predict the clinical outcome. Stromal-derived OPN probably has a different function compared with OPN secreted from tumor cells.

Abstract
Oral cancer is prevalent worldwide. Studies have indicated that an increase in the osteopontin (OPN) plasma level is correlated with the progression of oral cancer. Our previous report showed that the aqueous garlic extract S-allylcysteine (SAC) inhibited the epithelial–mesenchymal transition (EMT) of human oral cancer CAL-27 cells in vitro. Therefore, the present study investigated whether SAC consumption would help prevent tumour growth and progression, including the EMT, in a mouse xenograft model of oral cancer. The results demonstrated that SAC dose-dependently inhibited the growth of oral cancer in tumour-bearing mice. The histopathological and immunohistochemical staining results indicated that SAC was able to effectively suppress the tumour growth and progression of oral cancer in vivo. The chemopreventive effect of SAC was associated with the suppression of carcinogenesis factors such as N-methylpurine DNA glycosylase and OPN. SAC significantly suppressed the phosphorylation of Akt, mammalian target of rapamycin, inhibitor of κBα and extracellular signal-regulated kinase 1/2 in tumour tissues. The results demonstrated that the SAC-mediated suppression of cyclin D1 protein was associated with an augmented expression of the cell-cycle inhibitor p16Ink4. Furthermore, SAC inhibited the expression of cyclo-oxygenase-2, vimentin and NF-κB p65 (RelA). These results show that SAC has potential as an agent against tumour growth and the progression of oral cancer in a mouse xenograft model.

Abstract
INTRODUCTION Cancer is an extremely complex disease and most cancer treatments are limited to chemotherapy, radiation and surgery. The progression of tumours towards malignancy requires the interaction of various cytokines, growth factors, transcription factors and effector molecules. Osteopontin is a cytokine-like, calcium-binding, extracelular-matrix- associated member of the small integrin-binding ligand, N-linked glycoprotein (SIBLING) family of proteins. It plays an important role in determining the oncogenic potential of various cancers. The role of osteopontin in various pathophysiological conditions suggests that the alteration in post-translational modification result in different functional forms that might change its normal physiological functions. AREAS COVERED Osteopontin -based anticancer therapy, which may provide a new insight for the effective management of cancer. EXPERT OPINION A better understanding of the signalling mechanism by which osteopontin promotes tumourigenesis may be useful in crafting novel osteopontin -based anticancer therapy. The role of osteopontin in promoting cancer progression is the subject of in depth investigation and thus targeting osteopontin might be a suitable therapeutic approach for the treatment of cancer.

Abstract
Osteopontin (OPN) is an extracellular matrix protein in hard tissues. The polymorphism in promoter region of OPN gene correlates to different gene expression and might implicate potential roles in tumor progression and metastasis. Immunohistochemistry (IHC) was utilized to detect the OPN expression in 58 oral squamous cell carcinoma (OSCC) tissues and adjacent normal oral mucosa. The differential OPN expression was further analyzed in relation to clinico-pathological features. Genomic DNA was obtained from isolated leukocytes of blood samples of OSCC patients (n=100), and healthy individuals (n=97) from Taiwan. The OPN gene polymorphism was analyzed by direct sequencing. Our result showed OPN expression was significantly higher in OSCC tissues than in the paired adjacent normal tissues (p<0.01). The expression of OPN was significantly associated with nodal metastasis and the more advanced clinical stage (p<0.05). More prevalent -156 insGG/insGG genotype and -443 T/T genotype was found in OSCC patients (p<0.05). A significant difference in -443T/-156GG/-66T and -443C/-156G/-66T haplotypes between OSCC and controls (p<0.05) was also noted. The OPN expression in tumor tissues significantly correlated with -156 insGG/insGG and -156 G/G+insGG/G genotypes (p<0.05). The conclusion is tissue OPN expression correlates to OSCC progression. -156 insGG/insGG genotype is associated with OSCC susceptibility and higher OPN expression.

Abstract
OBJECTIVE Osteopontin (OPN) is a phosphorylated glycoprotein which is associated with tumor progression, development, and metastasis. Recently, it has been reported that OPN is highly upregulated in a variety of human malignancies. The aim of this study is to investigate the clinical significance of OPN mRNA expression in colorectal cancer (CRC). MATERIAL AND METHODS Conventional reverse transcription polymerase chain reaction (RT-PCR) and Western blot assays were performed to detect the expression of OPN mRNA and protein in human CRC cell lines and normal cell line. Real-time quantitative RT-PCR assay was performed to analyze the expression of OPN mRNA in 82 CRC tissue samples and corresponding non-tumor tissues. Immunohistochemistry was also performed to detect the expression of OPN protein in above tissues. Finally, the correlation between the status of OPN mRNA expression and clinicopathological factors and clinical outcome was evaluated. RESULTS Compared with normal human intestinal epithelial cell line, human CRC cell lines showed high level of OPN gene expression at both transcriptional and translational levels. Moreover, the results of real-time quantitative RT-PCR and immunohistochemistry showed that the expression levels of OPN mRNA and protein in tumor tissues were significantly higher than those in the corresponding non-tumor tissues (P < 0.001). The expression level of OPN mRNA was significantly correlated with lymph node metastasis, lymphatic or venous invasion, and TNM stage (P = 0.0033, 0.0061, 0.0008, and 0.0012, respectively). Moreover, we also observed that the disease-free and overall survival rates in patients with high OPN mRNA expression were significantly shorter than those in patients with low OPN mRNA expression (P = 0.0047 and 0.0125). Additionally, the status of OPN mRNA expression was an independent prognostic factor for the prognosis of CRC patients (P = 0.008; RR, 2.775; 95% confidence interval, 2.334-3.811). CONCLUSION OPN might play an important role in CRC progression and the status of OPN mRNA expression could be a novel prognostic molecular marker for CRC patients.

Abstract
Osteopontin is a molecule that promotes cellular proliferation as well as metastasis and plays a major role in the evolution of most systemic malignancies. Inhibition of carcinogenetic mechanisms that involve osteopontin will undoubtedly go a long way in controlling the growth of these tumors. A number of new molecules such as argatroban agelastatin A and selenium have been identified in this regard. For instance, Schulze et al. (in Breast Cancer Res Treat) have recently reported the successful utilization of argatroban for decreasing the growth of breast cancer tumor cells as well as their lymphatic metastasis. Similarly, anti osteopontin antibodies and antisense osteopontin RNA have been successfully used to inhibit tumor growth in prostate carcinomas and osteosarcomas, respectively. There is a clear and urgent need to expand the use of these molecules as well as to further identify other potent inhibitors of osteopontin mediated tumorigenesis.

Abstract
Connexins are gap-junction proteins forming hexameric structures in the plasma membranes of adjacent cells, thereby creating intercellular channels. Connexin 43 (CX43) is expressed in pulp tissue. However, its function in dental pulp tissue has yet to be fully investigated. We have employed antisense oligonucleotides (AS) against rat CX43 to study the role of CX43 in dental pulp cells. Cultured dental pulp cells were treated with AS or sense (S) oligonucleotides. The number of cells in the AS-treated groups was approximately 1.3-fold that in the S-treated controls. Growth rates were significantly different between the AS- and S-treated groups at 48 h (P < 0.01). An alkaline phosphatase assay revealed that AS-treated pulp cells dramatically decreased at 48 h after AS incorporation, whereas S-treated pulp cells showed no marked changes. Western blot analysis revealed that heat-shock protein 25 was highly expressed in S-treated cells but was only weakly expressed in AS-treated cells at 48 h. Furthermore, AS-treated cells highly expressed CX45, whereas S-treated cells exhibited high expression of CX32. These results suggest that CX43 is involved in cell growth, mineralization, and differentiation to odontoblasts in rat pulp cells, and that CX43 plays the opposite role to that of CX45.

Abstract
BACKGROUND Osteopontin (OPN) expression in squamous cell carcinoma (SCC) of the tongue has not been clearly elucidated. METHODS We selected 46 cases of tongue SCC and investigated the expression of OPN by immunohistochemical staining. The immunopositive reaction and score for each case were semiquantitatively evaluated. RESULTS Scores were significantly higher in carcinoma nests than in neighboring normal epithelium or epithelial dysplasia. The OPN was expressed clearly in the cytoplasm of carcinoma cells. In cases of early invasive carcinoma, in particular, expression of OPN showed a remarkable increase at the invasion front compared with the non-invaded regions. However, there was no significant correlation between expression of OPN in the primary tumor nest and lymphatic metastasis, recurrence, or survival rate. CONCLUSION This suggests that OPN is a useful biomarker of early invasion by SCC in tongue.

Oral Oncol 2007; 43:920-32. [PMID: 17306612 DOI: 10.1016/j.oraloncology.2006.11.011] [Citation(s) in RCA: 42] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2006] [Revised: 10/27/2006] [Accepted: 11/01/2006] [Indexed: 10/23/2022]
Abstract
Various combinations of the SIBLING family of proteins have been found to be up-regulated in many human cancers and have been linked to different stages of tumor progression, including metastasis. Bone sialoprotein (BSP), osteopontin (OPN) and dentin matrix protein 1 (DMP1) specifically bind and activate MMP-2, MMP-3, and MMP-9, respectively. These proteases have also been shown to play important roles in oral squamous cell carcinoma (OSCC) invasion and metastasis. However, with the exception of OPN, there are no reports on the expression of the family of five SIBLING proteins in OSCC. This study examines the expression patterns of the SIBLING family (and MMP partners when known) in OSCC, correlating expression to outcome variables. Archived paraffin sections of 87 cases of primary OSCC were screened by immunohistochemistry for the SIBLINGs and their MMP partners. Three SIBLINGs (BSP, DSPP, and OPN), were expressed in OSCC, while DMP1 and MEPE expression were never observed. Furthermore, BSP and OPN were always expressed with their known MMP partners, MMP-2 and MMP-3, respectively. Poorly differentiated tumors exhibited reduced or no immunoreactivity for BSP and OPN but increased immunoreactivity for DSPP. Seventy eight (90%) cases were positive for BSP and DSPP, while 79 cases (91%) were positive for OPN. Overall, 91% of the cases were positive for at least one SIBLING. There were no correlations between SIBLING expression and tumor size ("T"; of the Union Internationale Contre le Cancer [UICC]-TNM classification for OSCC), and between SIBLING expression and lymph node spread for the T1/T2 tumors. The levels of DSPP expression for floor of mouth and retromolar region tumors were higher than for tongue tumors. Statistically significant correlations were, however, found between the expression levels of BSP and MMP-2 (p<0.0001), BSP and MMP-3 (p<0.0001), and OPN and MMP-3 (p<0.0024). We conclude that BSP, DSPP, and OPN are highly up-regulated in OSCC. While the production of these SIBLINGs is independent of T, they correlate with oral location of tumor, cognate MMP expression, and for DSPP, the degree of tumor differentiation.

Abstract
PURPOSE To confirm the relationship between plasma osteopontin (OPN) levels and treatment outcomes in head and neck squamous cell carcinoma (HNSCC) patients in an expanded study. PATIENTS AND METHODS One hundred forty patients with newly diagnosed HNSCC were enrolled onto this study, 54 previously reported and 86 new patients. Pretreatment plasma OPN levels were assessed in all patients by an enzyme-linked immunosorbent assay method. OPN levels were correlated to treatment outcomes in the new group of patients. Detailed analyses were also performed on the relationship between OPN and tumor control rate, event-free survival (EFS), and postrelapse survival for the entire group. RESULTS Using a previously defined cut off point of 450 ng/mL, there was a significant correlation between OPN and freedom-from-relapse (P = .047), overall survival (P = .019), and EFS (P = .023) in the new, independent patient cohort (n = 86). Sequence of event analyses using the entire group (N = 140) revealed that OPN was an independent prognostic factor for initial tumor control, EFS in those who have achieved tumor control, and postrelapse survival. CONCLUSION In this expanded study, we were able to replicate the prognostic significance of OPN using a predefined cut off point in an independent patient group and demonstrated that plasma OPN is an independent prognostic marker for HNSCC.

Abstract
The present study investigated the expression and distribution of osteopontin in the mouse major salivary glands. The level of osteopontin expression in the mouse submandibular gland was higher (12.7-fold) than that in parotid and sublingual glands at the mRNA level. By Western blot analysis, intense positive bands were seen at the predicted molecular mass (about 55 kDa) in all the major salivary glands, while an approximately 30 kDa band of osteopontin was detected only in the submandibular gland. Indirect immunofluorescent and immuno-electron microscopy analyses demonstrated the localization of osteopontin in the luminal (apical) membranes of acinar cells in all the salivary glands. Osteopontin was also localized at the lumen of acini in the submandibular gland. These results suggest that the expression of osteopontin in the submandibular gland is different from that in the parotid and sublingual glands and that osteopontin may be degraded in the mouse submandibular gland.

Abstract
Osteopontin (OPN) is a non-collagenous extracellular matrix (ECM) protein expressed and secreted by several human cancers. This study investigated the expression pattern of OPN during development of oral squamous-cell carcinoma by using 7,12-dimethylbenz[a]anthracene (DMBA)-induced squamous-cell carcinomas in buccal pouch of syrian golden hamsters. We first identified the hamster OPN cDNA sequence by screening of a hamster calvariae cDNA library with a rat OPN cDNA probe. The resulting 1,449 bp of hamster OPN cDNA led to a deduced protein sequence of 305 amino acids containing several putative binding sites to integrins, CD44 receptors, calcium ions and hydroxyapatite, as well as multiple sites for phosphorylation, glycosylation and sulphation. Hamster OPN cDNA was then used as a probe to analyze the expression of OPN mRNA by Northern blot and in situ hybridization analyses of normal and malignant tissues. OPN mRNA was detected in several non-mineralized tissues as well as in mineralized tissues, but was not present in normal hamster buccal epithelium. DMBA-treated hamster buccal pouches expressed OPN mRNA as early as 4 weeks and displayed the highest level of expression at 15 weeks. The specimens treated with DMBA for 15 weeks exhibited histological features of squamous-cell carcinoma, presented microcrystalline deposits and showed OPN expression associated with malignant epithelium and tumor-associated macrophages. To summarize, our results suggest that buccal-pouch carcinogenesis of Syrian golden hamster may constitute an excellent experimental model to study the mechanisms by which OPN is associated with oral cancer pathogenesis, and to validate OPN-based therapeutic approaches to ameliorate oral cancer progression and metastasis.
