Areca catechu-(Betel-nut)-induced whole transcriptome changes in a human monocyte cell line that may have relevance to diabetes and obesity; a pilot study

ABSTRACT: Betel-nut consumption is the fourth most common addictive habit globally and there is good evidence linking the habit to obesity, type 2 diabetes (T2D) and the metabolic syndrome. The aim of our pilot study was to identify gene expression relevant to obesity, T2D and the metabolic syndrome using a genome-wide transcriptomic approach in a human monocyte cell line incubated with arecoline and its nitrosated products.

LncRNA expression profiles in areca nut chewing induced Tongue Squamous Cell Carcinoma (TSCC) and matched paracancerous tissues

Project description:Chewing betel nut is an important risk factor for the carcinogenesis of tongue squamous cell carcinoma (TSCC), but the mechanism is still unknown.To screen the lncRNAs associated with betel nut chewing-induced TSCC and identify potential biomarkers for the TSCC, we collected 5 pairs of TSCC and paracancerous tissues and monitored the resultant lncRNA and mRNA expression profiles using an lncRNA microarray. All 5 patients have a history of areca nut chewing.

Transcriptomic analysis of immortalized oral keratinocytes (n=2) and oral squamous cell carcinoma cells (n=5)

Project description:Due to betel nut chewing habit, oral cancer is the fourth leading cause of cancer death among Taiwanese men. In addition, oral cancer is the most common malignancy observed in men with 25-44 years old, alerting an urgent need to curb this disease. It is hypothesized that betel nut ingredients exhibit carcinogenic effects on the oral epithelium and alter local immune system. As a step to identify potential oncogenic gene fusions in Taiwanese oral cancer cells, total RNAs of two immortalized oral keratinocytes (CGHNK2, -K6) and five oral squamous cell carcinoma cell lines (C9, OC3, OEC-M1, TW2.6) were subjected to RNA-sequencing analysis, followed by an in-house bioinformatic pipeline for fusion gene detection.

Activation of TGF-beta pathway by areca nut constituents: A possible cause of Oral submucous fibrosis.

Project description:To understand the role of areca nut constituents in manifestation of Oral submucous fibrosis, we studied gene expression profile in epithelial cells following areca nut water extract treatment. A comaprison with TGF-beta induced gene expression changes were performed as epithelial cells were predicted to be source of TGF-beta. Control Vs Areca nut 5 ug/ml water extract (5H) (2), Contro Vs TGF-beta (2), Control Vs ALK5 (TbetaRI inhibitor) (2), Control Vs 5H + ALK5 inhibitor (2). (2)- Biological duplicates.

Role of areca nut induced TGF-β and epithelial mesenchymal interaction in pathogenesis of precancerous Oral submucous fibrosis

Project description:To understand the role of areca nut and TGF-β induced gene expression changes in fibroblasts and its contibution in the manifestation of Oral submucous fibrosis, we studied gene expression profile in primary human gingival fibroblast (hGF) cells following treatment with areca nut, TGF-β and both together. Control Vs Areca nut 5 µg/ml water extract (5H) (2), Contro Vs TGF-β (2), Control Vs Areca nut (5 µg/ml) and TGF-β (5 ng/ml) (5H+T) (2). (2)- Biological duplicates.

Development and application of mass spectrometric molecular networking for analyzing ingredients of areca nut

Project description:Areca nut(Areca catechu L.) is commonly consumed as a chewing food in the Asian region. However, the investigations into the components of areca nut are limited. In this study, we have developed an approach that combines mass spectrometry with feature-based molecular network to explore the chemical characteristics of the areca nut. In comparison to the conventional method, this technique demonstrates a superior capability in annotating unknown compounds present in areca nut. We annotated a total of 52 compounds, including one potential previously unreported alkaloids, one carbohydrate, and one phenol and confirmed the presence of 6 of them by comparing with commercial standards. The validated method was used to evaluate chemical features of areca nut at different growth stages, annotating 25 compounds as potential biomarkers for distinguishing areca nut growth stages. Therefore, this approach offers a rapid and accurate method for the component analysis of areca nut.

NSD3-NUT Fusion Oncoprotein in NUT Midline Carcinoma identified in 1221 patient-derived cell line by RNA-seq

Project description:Discarded live tumor tissue from a metastatic focus in the patientM-bM-^@M-^Ys lung was collected under institutional review board approval through the NUT midline carcinoma registry (www.NMCRegistry.org). From this tissue the first known NUT-variant cell line, 1221, was established. To determine the putative partner gene to NUT, we performed comprehensive RNA-sequencing on RNA purified from 1221. We identified an in-frame transcript fusing the 5M-bM-^@M-^Y coding sequence of NSD3 (exons 1-7) to exons 2-7 of NUT. Expression of the NSD3-NUT fusion oncoprotein was verified by immunobloting with an antibody to NUT, revealing an approximately 200kDa band that is similar in size to BRD3-NUT, but smaller than BRD4-NUT Identification of a NUT fusion partner using RNA extracted from live cultured 1221 cell line derived from a lung metastasis from the index case of a 13 year old female with NUT-positive NMC.
