Abstract
Telomerase is a ribonucleoprotein (RNP) responsible for the maintenance of chromosomal integrity by stabilizing telomere length. Telomerase is a widely expressed hallmark responsible for replicative immortality in 80-90% of malignant tumors. Cancer cells produce telomerase which prevents telomere shortening by adding telomeres sequences beyond Hayflick's limit; which enables them to divide uncontrollably. The activity of telomerase is relatively low in somatic cells and absent in normal cells, but the re-activation of this RNP in normal cells suppresses p53 activity which leads to the avoidance of senescence causing malignancy. Here, we have focused explicitly on various anti-telomerase therapies and telomerase-inhibiting molecules for the treatment of cancer. We have covered molecules that are reported in developmental, preclinical, and clinical trial stages as potent telomerase inhibitors. Apart from chemotherapy, we have also included details of immunotherapy, gene therapy, G-quadruplex stabilizers, and HSP-90 inhibitors. The purpose of this work is to discuss the challenges behind the development of novel telomerase inhibitors and to identify various perspectives for designing anti-telomerase compounds.

Abstract
BACKGROUND Oral squamous cell carcinoma (OSCC), the most common type of primary malignant tumor in the oral cavity, is a lethal disease with high recurrence and mortality rates. Butyrate, a metabolite produced by periodontal pathogens, has been linked to oral diseases. The purpose of this study was to evaluate the effect of sodium butyrate (NaB) on the proliferation, migration, and invasion of OSCC cells in vitro and to explore the potential mechanism. METHODS Two OSCC cell lines (HSC-4 and SCC-9) were treated with NaB at different concentrations. The cell proliferation was assayed by CCK-8, ethylene deoxyuridine (EdU), and flow cytometry. Wound healing and transwell assay were performed to detect cell migration and invasion. Changes in epithelial-mesenchymal transition (EMT) markers, including E-cadherin, Vimentin, and SNAI1, were evaluated by quantitative real-time PCR (qRT-PCR), western blot, and immunofluorescent staining. The expression levels of matrix metalloproteinases (MMPs) were analyzed by qRT-PCR and gelatin zymography. RESULTS Our results showed that NaB inhibited the proliferation of OSCC cells and induced cell cycle arrest at G1 phase, but NaB significantly enhanced cell migration and invasion compared with the control group. Further mechanistic investigation demonstrated that NaB induced EMT by increasing the expression of Vimentin and SNAI1, decreasing the expression of membrane-bound E-cadherin, and correspondingly promoting E-cadherin translocation from the membrane to the cytoplasm. In addition, the overexpression of MMP1/2/9/13 was closely related to NaB treatment. CONCLUSIONS Our study conclude that butyrate may promote the migration and invasion of OSCC cells by inducing EMT. These findings indicate that butyrate may contribute to OSCC metastasis.

Abstract
Head and neck squamous cell carcinoma (HNSCC) arises from the epithelial lining of the oral cavity, hypopharynx, oropharynx, and larynx. There are several potential risk factors that cause the generation of HNSCC, including cigarette smoking, alcohol consumption, betel quid chewing, inadequate nutrition, poor oral hygiene, HPV and Epstein–Barr virus, and Candida albicans infections. HNSCC has causative links to both environmental factors and genetic mutations, with the latter playing a more critical role in cancer progression. These molecular changes to epithelial cells include the inactivation of cancer suppressor genes and proto-oncogenes overexpression, resulting in tumour cell proliferation and distant metastasis. HNSCC patients have impaired dendritic cell (DC) and natural killer (NK) cell functions, increased production of higher immune-suppressive molecules, loss of regulatory T cells and co-stimulatory molecules and major histocompatibility complex (MHC) class Ι molecules, lower number of lymphocyte subsets, and a poor response to antigen-presenting cells. At present, the standard treatment modalities for HNSCC patients include surgery, chemotherapy and radiotherapy, and combinatorial therapy. Despite advances in the development of novel treatment modalities over the last few decades, survival rates of HNSCC patients have not increased. To establish effective immunotherapies, a greater understanding of interactions between the immune system and HNSCC is required, and there is a particular need to develop novel therapeutic options. A therapeutic cancer vaccine has been proposed as a promising method to improve outcome by inducing a powerful adaptive immune response that leads to cancer cell elimination. Compared with other vaccines, peptide cancer vaccines are more robust and specific. In the past few years, there have been remarkable achievements in peptide-based vaccines for HNSCC patients. Here, we summarize the latest molecular alterations in HNSCC, explore the immune response to HNSCC, and discuss the latest developments in peptide-based cancer vaccine strategies. This review highlights areas for valuable future research focusing on peptide-based cancer vaccines.

Abstract
Oral lichen planus (OLP) is a T cell-mediated common chronic inflammatory mucosal disease, with limited therapies available for long-term use. Previous study showed that ratio of genus Streptococcus decreased significantly in OLP patients when compared with controls. Buccal cotton swab samples of 43 OLP patients and 48 healthy individuals were collected for real-time quantitative polymerase chain reaction (RT-PCR) to investigate relative abundance alteration of Streptococcus salivarius in OLP lesions. Bacterial supernatants of S. salivarius ATCC® BAA-2593™ were collected by centrifugation and added to HSC-3 cells, and quantitative analysis of expression of IL-1β, IL-6, IL-8, and TNF-α in the HSC-3 cells was determined by RT-PCR. Then, a randomized, non-blinded, controlled study was conducted. Forty patients with symptomatic OLP were randomly allocated into two groups and received topical treatment of 0.1% triamcinolone acetonide dental paste (group A) and S. salivarius K12 lozenge (group B), respectively, for 4 weeks. Sign scores, visual analogue scale (VAS), and adverse reactions were recorded. Relative abundance of S. salivarius in the OLP group was lower than that of control group (P < 0.05). After treated with 0.1% supernatants of S. salivarius ATCC® BAA-2593™, the expression level of IL-6 in the HSC-3 cells significantly reduced (P < 0.001), while IL-1β, IL-8, and TNF- α showed a decreasing tendency (P > 0.05). There was significant reduction in sign scores and VAS scores in both groups after the 4-week treatment, with no significant difference between two groups. No adverse reaction was observed. S. salivarius might maintain local immune balance by inhibiting the NF-κB pathway. Topical application of Streptococcus salivarius K12 seemed to be effective in treatment of symptomatic OLP, especially with promising potential in long-term use. More detailed clinical studies with long follow-up period and standardized usage/dosage are expected to acquire definite conclusions.

Abstract
This study aims to investigate the effects of albendazole on pancreatic cancer cells and to explore the possible mechanisms involved. MTT, colony formation, wound healing and Transwell assays and immunocytochemistry analyses of proliferation antigen Ki-67 were employed to evaluate the role of albendazole in pancreatic cancer cell line proliferation and migration. Moreover, flow cytometry cell apoptosis evaluation was used for mechanism analysis. Finally, the in-vivo effects of albendazole were examined in an in-vivo nude mouse xenograft model. Compared to the control treatment, albendazole significantly decreased the growth of the pancreatic cancer cell lines SW1990 and PANC-1 in a time- and dose-dependent manner, as evidenced by decreased MTT absorbance, colony number and Ki-67 levels. Furthermore, albendazole decreased cell migration in 2- and 3-dimensional models in a dose-dependent manner. In addition, albendazole increased the apoptotic cell ratio in a dose-dependent manner. Finally, the in-vivo results confirmed that albendazole could decrease tumor growth. We demonstrated the inhibitory effects of albendazole on pancreatic cell proliferation and migration in vitro and in vivo, which indicate that albendazole might serve as a novel treatment modality for pancreatic cancer.

Abstract
Chronic stress and accelerated aging have been shown to impact the inflammatory response and related outcomes like sepsis and organ failure, but data are lacking in the trauma literature. The purpose of this study was to investigate potential relationships between pretrauma stress and posttrauma outcomes. The hypothesis was that pretrauma chronic stress accelerates aging, which increases susceptibility to posttrauma sepsis and organ failure. In this prospective, correlational study, chronic stress and accelerated biologic aging were compared to the occurrence of systemic inflammatory response syndrome, sepsis, and organ failure in trauma patients aged 18-44 years. Results supported the hypothesis with significant overall associations between susceptibility to sepsis and accelerated biologic aging (n = 142). There were also significant negative associations between mean cytokine levels and chronic stress. The strongest association was found between mean interleukin-1β (IL-1β) and human telomerase reverse transcriptase (hTERT), r(101) = -0.28), p = .004. Significant negative associations were found between mean cytokine levels, IL-12p70, r(108) = -0.20, p = .034; and tumor necrosis factor-α (TNF-α), r(108) = -0.20, p = .033, and positive life events via the behavioral measure of chronic stress. Results may help identify individuals at increased risk for poor outcomes of trauma and inform interventions that may reduce the risk for sepsis and organ failure.

Abstract
Telomerase activity contributes to cell immortalization by avoiding telomere shortening at each cell division; indeed, its catalytic subunit telomerase reverse transcriptase (TERT) is overexpressed in many tumors, including human oral squamous cell carcinoma (hOSCC). In these tumors, matrix metalloproteinases (MMPs), a group of zinc-dependent endopeptidases involved in cell migration, contribute to invasive potential of cancer cells. A proportion of hOSCC is associated with infection by high-risk human papillomavirus (HR-HPVs), whose E6 oncogene enhances TERT and MMPs expression, thus promoting cancer progression. Feline oral squamous cell carcinoma (FOSCC) is a malignant tumor with highly invasive phenotype; however, studies on telomerase activity, TERT, and MMPs expression are scarce. In this study, we demonstrate telomerase activity, expression of TERT, and its transcriptional activator cMyc along with expression of MMP-1, -2, and -9 in FOSCC-derived cell lines SCCF2 and SCCF3, suggesting a contribution by these pathways in cell immortalization and invasion in these tumors. Recent studies suggest that a sub-group of FOSCC as well as SCCF2 and SCCF3 are associated with Felis catus PV type-2 (FcaPV-2) infection. However, in this work, FcaPV-2 E6 gene knock-down caused no shift in either TERT, cMyc, or MMPs levels, suggesting that, unlike its human counterpart, the viral oncogene plays no role in their regulation.

Abstract
Telomerase is a ribonucleic reverse transcriptase enzyme that uses an integral RNA component as a template to add tandem telomeric DNA repeats, TTAGGG, at the 3' end of the chromosomes. 85-90% of human tumors and their derived cell lines predominantly express high levels of telomerase, therefore contributing to cancer cell development. However, in normal cells, telomerase activity is almost always absent except in germ cells and stem cells. This differential expression has been exploited to develop highly specific and potent cancer therapeutics. In this review, we outline recent advances in the development of telomerase inhibitors as anticancer agents.

Abstract
Cancer is a leading cause of death worldwide. Despite many research advancements in the field, the genetic changes
regulating the transformation of normal oral cells into malignant cells have not been fully elucidated. Several studies have
evaluated carcinogenesis at the molecular level. Cancer cell lines are commonly used in biomedical research because
they provide an unlimited source of cells and represent various stages of initiation and progression of carcinogenesis
in vitro. Aims: The objective of the study was to review original research articles using cancer cell lines as a tool to
understand carcinogenesis and to identify the genes involved in tumor development. Additionally, we also examined
the application of the genes as predictive biomarkers. Methods and Materials: Several databases, including PubMed,
Google Scholar, Ebsco, and Science Direct, were searched from 1985 to December 2016 using various combinations of
the following key words: “mouth neoplasm”, “cell lines”, and “tumorigenesis”. Original experimental studies published
in English were included. We excluded letters to the editor, historic reviews, and unpublished data from the analysis.
Results: There were 17 studies (in vitro) included in the analysis. There were 14 genes and 4 miRNAs involved in
malignant transformation of oral keratinocytes into cancer cells. The most commonly studied genes were p53, cyclin
D1, and hTERT. Conclusion: Additional reviews and studies are needed to identify a panel of genes specific to various
potentially malignant disorders and to aid in the early detection of oral squamous cell carcinoma (OSCC) because
tumorigenesis involves the mutation of multiple genes. Furthermore, improving advanced cost-effective diagnostic
methods may benefit the public health sector.

Abstract
The "Hallmarks of Cancer" describe the ways by which cancer cells bypass homeostasis. Escape from replicative senescence is one of the earliest features of cancer cells. Maintenance of the telomeres through reactivation of telomerase was initially associated with replicative immortality in various cancers. The shelterin complex, a telomeric hexaprotein association, plays a key role in telomere maintenance and in the hallmarks of cancer. Some shelterin proteins are overexpressed in diverse cancers and can promote tumorigenesis in animal models. Shelterin can also have an impact on tumor size, tumor growth and resistance to treatment. Studies into the expression level of shelterin in oral squamous cell carcinoma (OSCC) report contradictory results. Moreover, the exact role of these proteins in OSCC tumorigenesis remains uncertain. In this review, we examined the data linking telomeres and hallmarks of OSCC. Furthermore, we examined the literature concerning telomeres and the clinical outcome of OSCC. Finally, we propose a model encompassing the role of shelterin proteins in oral tumorigenesis and treatment outcome.
