Genome-wide transcriptional profiling of HIV positive and negative adults with active tuberculosis, latent TB infection and other diseases

ABSTRACT: The study aimed to define transcriptional signatures for detection of active TB (TB) compared to latent TB infection (LTBI) as well as to other diseases (OD) with similar clinical phenotypes in patients with and without HIV in two African adult populations. Transcriptional signatures were identified that distinguished active TB from LTBI, active TB from other diseases, and active TB from both LTBI and other diseases in HIV+/- patients. Adults were recruited from Cape Town, South Africa (n=300) and Karonga, Malawi (n=237) who were either HIV+ or HIV - with either active TB, LTBI or OD. Blood was collected into PAX gene tubes (PreAnalytiX). Total RNA integrity was assessed using an Agilent 2100 Bioanalyzer (Agilent, Palo Alto, CA). Labeled cRNA was hybridized to Illumina Human HT-12 Beadchips. Data were analysed in R.

Whole genome expression analysis of SaOS2 cells expressing anti-sense APC RNA

Project description:Osteoblasts represent an important cell type playing a role in not only bone formation but also regulate hematopoiesis by secreting factor as well as via contact with hematopoietic stem cells in the bone marrow. Since Wnt signalling plays an important role in osteoblast differentiation, we were interested in looking at how canonical Wnt signalling activation in osteoblastic cells is likely to affect hematopoietic cell adhesion and regulate their fate. Endogenous Wnt signaling activation in osteoblastic SaOS2 cells was achieved by generating doxycycline (DOX) inducible antisense-APC expressing SaOS2 cells. Gene expression profiling was performed on SaOS2 cells induced with DOX (1Î¼g/ml) for 3 days and further on DOX treated cells allowed to recover for 3 days. The results reveal changes in expression of a number of cell adhesion and extracellular matrix protein genes as well as genes involved in osteoblast differentiation. Doxycycline inducible antisense APC expressing SaOS2 cells were treated with DOX for 3 days and compared with control (untreated) cells. In addition, a set of DOX induced cells was further cultured for 3 days in absence of Dox to allow for the cells to recover and see the change in gene expression compared to Dox treated and control cells. All experiments were done in triplicates (in total 9 samples).

Transcriptomic profiling in childhood H1N1/09 influenza reveals reduced expression of protein synthesis genes

Project description:In order to understand the immunopathogenesis of severe influenza H1N1/09, we compared the whole blood RNA transcriptome of children hospitalised with H1N1/09 infection with that of children hospitalised with RSV or bacterial infection Blood was collected into PAX gene tubes (PreAnalytiX). Total RNA integrity was assessed using an Agilent 2100 Bioanalyzer (Agilent, Palo Alto, CA). Labeled cRNA was hybridized to Illumina Human HT-12 v3 Beadchips. Observational, prospective study. Patients were recruited at or after presentation to hospital. Main inclusion criteria were presence of illness of sufficient severity to warrant blood tests for clinical reasons, in child aged <17 years. Patient numbers recruited were as follows: H1N1/09 infection (n=25) RSV (n=34) (n=21), and healthy paediatric controls (n=33). After exclusion of children with co-infections, numbers of arrays analysed in were as follows: H1N1/09 n=19; RSV n=22; bacterial infection n=18; controls n=33

Molecular Characterization of Heat Intolerance in Mice (mRNA data)

Project description:Prolonged exposure to high temperatures may cause heat-related illnesses, such as cramps, syncope, exhaustion or even stroke in some individuals. Heat-related injuries remain a threat to the health and operational effectiveness of military personnel, athletes and the general public. Heat injury victims experience long-term complications that may include multi-system organ (liver, kidney, muscle) and neurologic damage, as well as reduced exercise capacity and heat intolerance. Findings from our laboratory using a developed heat stress model show that about 1/3 of mice are heat-intolerant and vulnerable to heat injury even though they are from the same mice litter. We examined if there is any genetic causation to this pattern of observation between the two groups of mice classified (Heat Intolerant and Heat Tolerant). We would like to screen Heat Tolerant and Heat Intolerant mice samples using microarray technology and examine their microRNA and mRNA for possible gene-specific differences between the two groups (6 mice per group). The results from this proposed animal research will help identify and select potential markers that can be used as a pre-screen to identify heat intolerance and assess heat injury recovery in humans. Heat-induced physiological and biochemical changes were assessed to determine heat tolerance levels in mice. We performed mRNA and microRNA expression profiling on mouse gastrocnemius muscle tissue samples to determine novel biological pathways associated with heat tolerance.
