Prion protein is associated with a worse prognosis of head and neck squamous cell carcinoma. J Oral Pathol Med 2021; 50:985-994.

Abstract
BACKGROUND Head and neck squamous cell carcinoma (HNSC) etiopathogenesis remains unclear, and the biological changes with the activation of heat shock proteins (HSPs) and prion protein (PRNP) promoted by hypoxia in HNSC are undetermined. This study investigates hypoxia's effect in lymph node metastasis by PRNP expression changes and its main partners. METHODS The study combined a theoretical/cell culture study with a case-control study. First, bioinformatics and cell culture were performed. A case-control study was performed in a second step by comparing HNSC patients with and without lymph node metastasis. ANALYSES The Cancer Genome Atlas (TCGA) data source validates the theory in the global population study. RESULTS Bioinformatics analysis suggests that hypoxia-inducible factor-1α (HIF1A) is associated with HSPA4, HSP90AA1 and PRNP expression. TCGA data validate the hypothesis that higher HSP90AA1, HSPA4 and PRNP are related to metastases and low survival. Herein, the cell study demonstrated that muted PRNP did not respond to hypoxia. DISCUSSION Our results collectively provide the first evidence that PRNP promotes HNSC lymph node metastasis progression through the upregulation of HSPA4, HSP90AA1 and HIF1A. Our findings may provide a molecular basis for the promoting Role of PRNP in HNSC progression.

A review of the anticancer activity of Azadirachta indica (Neem) in oral cancer. J Oral Biol Craniofac Res 2020; 10:206-209. [PMID: 32489822 DOI: 10.1016/j.jobcr.2020.04.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2020] [Revised: 04/09/2020] [Accepted: 04/11/2020] [Indexed: 02/07/2023] Open
Abstract
Background Azadirachta indica (neem), belongs to the family of Meliaceae plants, is found in the Indian subcontinent. The neem tree is colloquially referred to as the village pharmacy due to its array of biological properties. Every part of the neem tree like its bark, leaves, sap, fruit, seeds, and twigs find a multitude of uses. It is customary to use them for management of skin diseases and various other infections.The anticancer properties of neem have been studied in the past and these include its ability to modulate the tumour environment, increase the cytotoxic ability of host monocytes and suppress the proliferation of tumour cells. The present review was conducted with the objective of scrutinizing and assimilating data about the usefulness Azadirachta indica in oral cancer from all the previously done work. Material and methods A planned review was conducted of all the studies that investigated the role of Azadirachta indica in oral cancer. Literature search was carried out using PubMed, Scopus and Google scholar databases. In addition to electronic searching, hand searching, cross referencing and various internet engines were also used to collect data. The articles were perused and articles not pertinent to our search were omitted. Results and conclusion The anticancer properties of neem were evaluated and the active constituents of neem have been demonstrated to unequivocally have preventive and therapeutic potential against oral cancer. Although, greater exploration of the anticancer properties of neem are required in order to effectively integrate it into the routine management of oral cancer.

J Oral Pathol Med 2020; 49:665-671. [PMID: 32128880 DOI: 10.1111/jop.13007] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2019] [Revised: 09/13/2019] [Accepted: 02/19/2020] [Indexed: 11/30/2022]
Abstract
BACKGROUND Heat shock proteins (HSPs) are released in response to stress situations, such as heat, inflammation, and infection. They are also involved in the tumor cell proliferation and prevention of apoptosis. Heat shock protein 105 (Hsp105/110) is a high-molecular-weight protein, which has been reported in many cancer types but few studies have been carried out on oral squamous cell carcinoma (OSCC). In the current study, we have focused on HSP105 expression on OSCC and evaluated their correlation with tumor clinicopathological parameters and patients' survival. METHODS A retrospective study included 70 patients with OSCC of which 50 patients (71.4%) were male and 20 (28.6%) were female. The patient's information, including age, location, TNM stage, histological grade, regional metastasis, recurrence, and survival, were collected. Immunohistochemical staining for HSP105 was performed. The healthy oral mucosa (n = 10) was used as a control. The staining intensity and percentage of stained cells were semi-quantitatively evaluated, and HSP105 expression was correlated with tumor clinicopathological features and patient survival. RESULTS Statistical analysis for HSP105 showed that there was no significant correlation with tumor clinicopathological features. However, HSP105 overexpression was associated with a decrease in the duration of patients' survival (P = .042). CONCLUSION This result suggests that the increased expression of the HSP105 in the OSCC could be a prognostic factor for malignancy.

Abstract
Heat-shock proteins (HSPs), one of the evolutionarily conserved protein families, are widely found in various organisms, and play important physiological functions. Nevertheless, HSPs have not been systematically analyzed in esophageal squamous cell carcinoma (ESCC). In this study, we applied the protein-protein interaction (PPI) network methodology to explore the characteristics of HSPs, and integrate their expression in ESCC. First, differentially expressed HSPs in ESCC were identified from our previous RNA-seq data. By constructing a specific PPI network, we found differentially expressed HSPs interacted with hundreds of neighboring proteins. Subcellular localization analyses demonstrated that HSPs and their interacting proteins distributed in multiple layers, from membrane to nucleus. Functional enrichment annotation analyses revealed known and potential functions for HSPs. KEGG pathway analyses identified four significant enrichment pathways. Moreover, three HSPs (DNAJC5B, HSPA1B, and HSPH1) could serve as promising targets for prognostic prediction in ESCC, suggesting these HSPs might play a significant role in the development of ESCC. These multiple bioinformatics analyses have provided a comprehensive view of the roles of heat-shock proteins in esophageal squamous cell carcinoma.

CD20+ Tumor Infiltrating B Lymphocyte in Oral Squamous Cell Carcinoma: Correlation with Clinicopathologic Characteristics and Heat Shock Protein 70 Expression. PATHOLOGY RESEARCH INTERNATIONAL 2018; 2018:4810751. [PMID: 29850009 PMCID: PMC5904773 DOI: 10.1155/2018/4810751] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/06/2017] [Revised: 02/16/2018] [Accepted: 03/05/2018] [Indexed: 12/23/2022]
Abstract
Objective B lymphocyte infiltration in the tumor microenvironment has been proposed to play pivotal roles in tumor progression. Heat shock protein 70 (HSP70) expressed by tumor cells can induce antitumor immune response. Few studies have examined the clinicopathologic relationship between tumor infiltrating B lymphocyte and HSP70 expression in human cancer. So far, there is no complete knowledge on the relationship in oral squamous cell carcinoma (OSCC). The present study was conducted to evaluate the relationship between tumor infiltrating B lymphocyte and HSP70 expression in OSCC, as well as the clinical outcome. Materials and Methods In this retrospective study, the immunohistochemical analysis of 50 OSCC specimens was performed using CD20 and HSP70 antibodies. The relationship between markers' expression and clinicopathologic data was evaluated using Mann–Whitney test, Chi-square test, logistic regression model, and Spearman's correlation coefficient. Results The data analysis showed significant correlation between peritumoral CD20+ B lymphocyte infiltration and lymph node metastasis (P = 0.047). Furthermore, HSP70 expression was significantly correlated with stage (P = 0.003), lymph node metastasis (P < 0.001), and tumor size (P = 0.044). However, no relationship was observed between B lymphocyte infiltration and HSP70 expression. Conclusion The results suggest that peritumoral B lymphocyte infiltration and HSP70 expression level have significant association with OSCC and may be considered as prognostic indicators in OSCC. Thus, evaluation of B cells as therapeutic targets in OSCC patients is recommended.
