Project description:The purpose of this study is the investigation of new host-microbiome interactions promoting adenoma formation and adenocarcinoma progression. For that purpose, the investigators will collect saliva, stool and colon biopsy specimens from patients referred to colonoscopy or surgical resection of colorectal tumor. Besides, a questionnaire about diet, lifestyle and medical history will be collected. Sample analysis will involve simultaneous characterization of host and microbiota genomic and transcriptomic components.
Project description:NO-CUT is a one-stage phase II trial seeking to establish whether an oxaliplatin-based chemotherapy preceding standard neo-adjuvant fluoropyrimidines-based chemo radiotherapy, can safely spare demolitive surgical intervention in patients with operable rectal cancer, without increasing the risk of distant relapse. The trial also has a translational component aimed at establishing whether selected genomic, epigenetic, and transcriptomic markers are predictive of tumor and patient outcome.
Project description:We reconstructed the Virulence Regulatory Network (VRN) of R. solanacearum strain GMI1000 by collecting bibliographical information based on genetic and genomic studies, including three transcriptomic studies. The reconstructed R. solanacearum VRN comprises 712 genes including 29 genes coding for transcription factors and 34 proteins involved in signal transduction. This VRN perceives 86 signals and controls the expression of 606 genes.
Project description:Oral cavity Squamous Cell Carcinoma (OCSCC) is a common form of head and neck cancer through the developed and developing world. However, the etiology of OCSCC is still unclear. To explore whether smoking, HPV and/or other underlying genetic and transcriptomic changes could be responsible for the oncogenesis events for OCSCC. A prospective observational study of fresh tissue biopsy from 45 participants with OCSCC collected from Brisbane Head and Neck Clinics between 2013 to 2015. Exploration of the genetic and transcriptomic landscape was performed using RNA sequencing and whole exome sequencing. Identification of HPV was to be performed using DNA PCR genotyping and RNA sequencing. Patient medical records were retrieved and the patient demographics were used to correlate with genomic and transcriptomics analyses, including the location of the tumor within the oral cavity, smoking and alcohol histories.
