Transcriptome analysis of normal oral cells and oral cancer cells treated with elemental diet (ED) Elental®

ABSTRACT: Purpose: Previously, we have reported the effectiveness of elemental diet (ED) Elental® against radiotherapy- or chemoradiotherapy- induced oral mucositis (Support Care Cancer 2016, Mol Clin Oncol 2019). However, administration of additional nutrition or ED in oral cancer patients might also provide extra nutrition for cancer cells, which could result in cancer development. At present, it is still unclear whether the beneficial effect of ED can be expected to surpass its possible harmful effect on oral cancer treatment. In the present study, we tried to clarify whether Elental® has different effects on human oral keratinocyte (HOK) cells compared to oral squamous cell carcinoma (OSCC) cells (HSC2). Method: Gene expression profiles of HOK cells and HSC2 cells treated with Elental® were generated by deep sequencing. Results: Whole transcriptome analysis data suggested that Elental® helped in the proliferation and survival of HOK through the induction of ERK. Moreover, Elental® added stress to HSC2 through the induction of endoplasmic reticulum stress response marker, BiP. Our results showed that Elental® might add stress to HSC2, and provide growth stimulation to HOK. Conclusion: Whole transcriptome analysis showed different gene expression profile between HOK cells and HSC2 cells treated with Elental®, suggesting that effects of Elental® might differ between normal oral cells and oral cancer cells.

An elemental diet protects mouse salivary glands from 5-fluorouracil-induced atrophy.

Project description:In cancer patients, an elemental diet (ED) reduces adverse effects of chemotherapy, including oral mucositis. However, the detailed mechanism(s) of the healing effects of an ED remains unclear. In this study, the protective effects of the ED, Elental®, were examined against 5-fluorouracil (5-FU)-induced oral mucositis and salivary gland atrophy in mice. Mucositis was induced in female ICR mice by injection of 5-FU. The mice were orally administered Elental® (ED group) or saline (control group). After treatment, whole transcriptome analysis and network analysis were conducted to understand the mechanism(s) of action of Elental® against oral mucositis. Whole transcriptome analysis and Ingenuity Pathways Analysis (IPA) data suggested that Elental® contributed to the recovery of mitochondrial function in 5-FU-damaged salivary glands.

Gene expression profilings of normal human oral keratinocyte (HOK) and dysplastic oral keratinocyte cell line from a heavy smoker (DOK)

Project description:In our previous study, we identified global genetic and epigenetic aberrations in the tumors of oral squamous cell carcinoma (OSCC) patients who were habitual smokers. We hypothesized that cigarette smoke might play a role in oral malignant transformation. DOK cell line is a dysplasitc oral keratinocyte derived from a heavy smoker with OSCC. The differentially expressed genes between DOK and normal human oral keratinocytes (HOK) may provide important information about OSCC carcinogenesis mediated by cigarette smoking. Total RNA was collected from DOK and HOK cells followed by gene expression microarray analysis.

Genome-wide profiling of small RNAs in human Oral squamous cell carcinoma (OSCC) cell lines

Project description:To elucidate the potential role of small ncRNAs, such as piRNAs and miRNAs in oncogenesis of Oral squamous cell carcinoma (OSCC), we performed genome wide profiling in three human OSCC cell lines, H357 (tongue squamous cell carcinoma), KB (mouth cancer), Hep-2 (laryngeal cancer), and HOK (Normal human oral keratinocyte) using high-throughput RNA sequencing (RNA-Seq) of small RNAs. We discovered 4854 piRNAs in H357, 5184 in KB, 8340 in Hep-2, and 4735 in HOK, while miRNAs in H357, KB, Hep-2, and HOK were 1538, 1533, 1257, and 1468, respectively. This is the first study to identify both piRNAs and miRNAs in OSCCs, which will serve as a future resource for understanding the molecular mechanisms underlying the complex neoplastic events mediated by these small RNAs. Furthermore, these piRNAs and miRNAs have the potential to be used as biomarkers for OSCC.

High-throughput RNA sequencing of transcriptomes expressed in Oral squamous cell carcinoma (OSCC) and human oral keratinocytes (HOK)

Project description:Next-generation sequencing (NGS) has transformed systems-based analysis in the molecular landscapes of various cancer types. The goals of this study are to obtain transcriptomes expressed in human oral squamous cell carcinoma (OSCC) cell lines. The transcriptome profiles of OSCC cell lines (H357, KB and Hep-2) and normal Human oral keratinocytes (HOK) were obtained from the high throughput RNA sequencing sequencing using Illumina Hiseq2500 platform. We obtained 10160, 10251, 10191, 10201 transcripts expressed in HOK, H357, KB, and Hep-2 respectively, which include protein coding genes (PCGs), lncRNAs, pseudogenes and others. Our results showed a set of transcripts that are dysregulated in OSCC, which might be playing some key roles in tumorigenesis process. Further in-depth analysis might provide clues for better understanding of gene function in OSCC.

Transcription profiling of human proliferating oral keratinocytes isolated from normal gingival tissue infected with retorviruses expressing E6 and E6(delta)118-122

Project description:The goal of this study is to identify genes that are differentially expressed by E6 in oral epithelial cells that are stably expressing Bmi-1. Experiment Overall Design: Primary Normal human oral keratinocytes (NHOK) is explanted from normal human gingival tissue. The cells were infected with retroviruses capable of expressing Bmi-1 and being selected. Actively dividing HOK/Bm-1 cells were then superinfected with LXSN-based retorviruses capable of expressing E6 and E6(delta)118-122, and selected. Actively proliferating cells are then harvested to isolate total RNA which was subsequently subjected to microarray analysis.
