Project description:Tongue squamous cell carcinoma is a tumour type with rather low five year survival, around 60%. The poor survival rate has been ascribed to late detection, a high frequency of locoregional recurrence, the occurrence of secondary primary tumours and death due to comorbidity. One reason for development of recurrence is thought to be the existence of transformed cells in areas adjacent to the primary tumour, cancerization field effect. The aim of this study was to map the changes in the tumour free tongue tissue adjacent to tongue tumours compared with healthy control tongue tissue to better understand the cancerization field effect. Tissue biopsies were collected from tumour (T) and tumour free tissue adjacent to the tumour (TF) from patients with tongue squamous cell carcinoma. Control tissue was collected from latter border of the tongue of tumour free healthy volunteers (C). All samples were homogenized and RNA was extracted. The RNA was biotin labelled and run on Illumina HT-12 bead chip array.
Project description:A majority of individuals infected with human immunodeficiency virus (HIV) have inadequate access to antiretroviral therapy and ultimately develop debilitating oral infections that often correlate with disease progression. Our study evaluates the potential of simian immunodeficiency virus (SIV) infected rhesus macaques to serve as a non-human primate model for oral manifestations of HIV disease. Microarrays were used to characterize changes in gene expression in the tongue mucosa that occur during chronic SIV infection. Dorsal tongue tissues from healthy uninfected macaques and macaques with chronic stage SIV infection were used for RNA extraction and hybridization on Affymetrix microarrays.

Microarrays were used to characterize changes in gene expression in the dorsal tongue epithelium that occur during chronic SIV infection. Epithelial cells were laser microdissected from dorsal tongue tissue sections from healthy uninfected macaques and macaques with chronic stage SIV infection and used for RNA extraction and hybridization on Affymetrix microarrays.
Project description:dataset for metaproteomics analysis to characterize of the composition of salivary and tongue microbial communities within healthy subjects in the range of age between 20-30 years
Project description:Base of tongue squamous cell carcinoma (BTSCC) is a common tumor of oropharynx worldwide. In addition, BTSCC is a lethal disease and its treatment results in significant disability. Considerable importance is given in lifestyle, particularly tobacco and alcohol use, in cases of BTSCC. It was postulated that BTSCC arises if the ability to metabolize carcinogens, to repair DNA damage and to control cell signaling and cell cycle are defective in individuals with continued exposure to benzo(a)pyrene, ethanol and acetaldehyde. Since these abilities are inherited and vary among human beings, healthy individuals may be at distinct risks for BTSCC. Affymetrix SNP arrays were performed according to the manufacturer's directions on DNA extracted from peripheral blood samples.
Project description:Metagenome data from soil samples were collected at 0 to 10cm deep from 2 avocado orchards in Channybearup, Western Australia, in 2024. Amplicon sequence variant (ASV) tables were constructed based on the DADA2 pipeline with default parameters.
