Project description:Exosomes were isolared from saliva od healthy individuals and head and neck cancer (HNSCC) patients.miRNA profiling of saliva-derived exosomes was perfomred using nCounter SPRINT system. Samples were grouped according to Healthy and Tumor based on their saliva-derived exosomal miRNA profile.

Project description:The current study makes use of NanoString targeted technology to profile urinary exosomal miRNAs from IgA nephropathy affected patients and corresponding healthy controls. Circulatory biomarkers were detected for IgA nephropathy from Indian cohort which can be made used for the diagnostic therapy. 14 miRNAs were detected to be related to the disregulation in miRNome of IgA nephropathy patients using lasso feature selection method, out of which multiple miRNAs like hsa.mir.146b.3p, hsa.mir.599 and many more was resulted with high AUROC values >=0.9 efficient in differentiating between healthy controls and IgA nephropathy condition. These markers can be use further in the diagnosis and treatment of IgAN.

Project description:Human saliva microbiota is phylogenetically divergent among host individuals yet their roles in health and disease are poorly appreciated. We employed a microbial functional gene microarray, HuMiChip 1.0, to reconstruct the global functional profiles of human saliva microbiota from ten healthy and ten caries-active adults. Saliva microbiota in the pilot population featured a vast diversity of functional genes. No significant distinction in gene number or diversity indices was observed between healthy and caries-active microbiota. However, co-presence network analysis of functional genes revealed that caries-active microbiota was more divergent in non-core genes than healthy microbiota, despite both groups exhibited a similar degree of conservation at their respective core genes. Furthermore, functional gene structure of saliva microbiota could potentially distinguish caries-active patients from healthy hosts. Microbial functions such as Diaminopimelate epimerase, Prephenate dehydrogenase, Pyruvate-formate lyase and N-acetylmuramoyl-L-alanine amidase were significantly linked to caries. Therefore, saliva microbiota carried disease-associated functional signatures, which could be potentially exploited for caries diagnosis. The DMFT INDEX (Decayed, Missing, Filled [DMF] teeth index used in dental epidemiology) values are provided for each sample We employed a microbial functional gene microarray, HuMiChip 1.0, to reconstruct the global functional profiles of human saliva microbiota from ten healthy and ten caries-active adults.

Project description:Saliva is a convenient non-invasive source of liquid biopsy to monitor human health and diagnose diseases. In particular, extracellular vesicles (EVs) in saliva can potentially reveal clinically relevant information for systemic health. Recent studies have shown that RNA in saliva EVs could be exploited as biomarkers for disease diagnosis. However, there is no standardized protocol for profiling RNA in saliva EV nor clear guideline on selecting saliva fractions for biomarker analysis. To address these issues, we established a robust protocol for small RNA profiling from fractionated saliva. With this method, we performed comprehensive small RNA sequencing of four saliva fractions, including cell-free saliva (CFS), EV-depleted saliva (EV-D), exosome (EXO), and microvesicle (MV) from ten healthy volunteers.

Project description:In this paper, we first report that EC smoking significantly increases the odds of gingival inflammation. Then, we seek to identify and explain the mechanism that underlies the relationship between EC smoking and gingival inflammation via the oral microbiome. We performed mediation analyses to assess if EC smoking affects the oral microbiome, which in turn affects gingival inflammation. For this, we collected saliva and subgingival samples from EC users and non-users and profiled their microbial compositions via 16S rRNA amplicon sequencing. We then performed α-diversity, β-diversity, and taxonomic differential analyses to survey the disparity in microbial composition between EC users and non-users. We found significant increases in α-diversity in EC users and disparities in β-diversity between EC users and non-users.

Project description:41% of all oral carcinomas have been found to localize at tongue, where they were characterized as being aggressive and having capacity to locally invade and relapse frequently. Despite considerable enhancements in the cancer diagnosis and treatment techniques, tongue squamous cell carcinoma (TSCC) still remains to be one of the most common and lethal cancer types in the head and neck region. In this study, we aimed to identify a signature of saliva-specific microRNAs (miRNAs) expression in TSCC patients. To explore putative diagnostic biomarkers, we compared the miRNA profiles of saliva samples obtained from 3 TSCC patients and 4 healthy control individual using Agilent miRNA microarray (V19). Three of the differentially expressed miRNAs were selected for further validation with quantitative reverse-transcription PCR (qRT-PCR) using saliva samples of 25 TSCC patients and 25 healthy control individuals. Microarray analysis demonstrated that 428 miRNA probes were deregulated in TSCC patients when compared to control group and qRT-PCR results validated the reduced expression of miR-139-5p in TSCC saliva. Further analysis of post-operative saliva samples of TSCC patients revealed that miR-139-5p level elevated to normal level after surgery, pointing its diagnostic and prognostic power. As a conclusion, we propose saliva as a feasible source in routine patient examination for early diagnosis of TSCC patients, and our results suggest saliva miR-139-5p as a novel potential diagnostic marker.
