Gut microbes elicit specific changes in gene expression in the colon of mice. We colonized germ-free mice with microbial communities from the guts of humans, zebrafish and termites, human skin and tongue, soil and estuarine microbial mats.
Bacteria from diverse habitats colonize and compete in the mouse gut.

View SamplesIn neural stem cells, stimulation of the death receptor CD95 does not trigger apoptosis but resulted in increased stem cell survival and neuronal specification via activation of the Src /PI3K /AKT/mTOR signalling pathway. To further characterize CD95-dependent neural stem cell survival and differentiation we used conventional gene expression profiling combined with translation state array analysis. Mouse neural stem cells grown in neurosphere cultures were stimulated with a trimerized CD95L construct (CD95L-T4) and total as well as polysomal bound RNA was isolated 48 hours after stimulation and analysed by microarrays. CD95L-T4 treatment induced a global increase in ribosome-bound mRNA and protein translation as well as changes on genes involved in neurogenesis, protein synthesis and transcription factors.

View SamplesLiquid biopsies have demonstrated that the constitutively active androgen receptor splice variant-7 (AR-V7) associates with reduced response and overall survival (OS) from endocrine therapies in castration resistant prostate cancer (CRPC). However, these studies provide little information pertaining to AR-V7 biology and expression in prostate cancer (PC) tissue. Following generation and validation of a novel AR-V7 antibody for immunohistochemistry (IHC); nuclear AR-V7 protein expression was determined for 358 primary prostate samples (358 patients) and 293 metastatic biopsies (194 patients). Associations with disease progression, nuclear AR full length (AR-FL) expression, response to abiraterone and/or enzalutamide, and gene signatures (from three independent cohorts) was determined. Overall design: RNA sequencing of metastases from individuals with castration resistant prostate cancer (CRPC) using Illumina HiSeq 2500.

View SamplesCoordinated regulation of the ubiquitin-proteasome system is crucial for the cell to adjust its protein degradation capacity to changing proteolytic requirements. The transcription factor TCF11 has been identified as a regulator for 26S-proteasome formation in human cells to compensate for reduced proteolytic activity. To expand the current knowledge of other UPS-related TCF11 target genes in response to epoxomicin, we performed microarray analyses of cells exposed to epoxomicin and with or without depletion of TCF11.
Proteasomal degradation is transcriptionally controlled by TCF11 via an ERAD-dependent feedback loop.

View SamplesChronic tendon injuries, also known as tendinopathy, are common among professional and recreational athletes. These injuries result in a significant amount of morbidity and health care expenditure and yet little is known about the molecular mechanism leading to tendinopathy. We have used histological evaluation and molecular profiling to determine the gene expression changes in 23 human patients undergoing surgical procedures for the treatment of chronic tendinopathy. Diseased tendons have altered extracellular matrix, fiber disorientation, increased cellular content and vasculature and the absence of inflammatory cells. Global gene expression profiling identified 1783 transcripts with significant different expression patterns in the diseased tendons. Global pathway analysis further suggests altered expression of extracellular matrix proteins and the lack of an appreciable inflammatory response. We have identified pathways and genes regulated in tendinopathy samples that will help contribute to the understanding of the disease towards the development of novel therapeutics.

View SamplesDrugs directly targeting Hepatitis C (HCV) are often rendered useless by the high mutation rate of the virus. Thus, we deduce that targeting of host factor that affect HCV replication may provide enhanced therapy fort HCV infection. Hepatocyte cell line Huh7 is known to be non-permissive for Hepatits C (HCV) replication. Through a method developed by the Rice laboratory (Blight, K.J., et al., J Virol, 2002), selection of a small subset of permissive hepatocytes is possible. The Rice laboratory generated the first permissive cell line, Huh7.5, using this method. We generated another permissive cell line, HRP1, using the same method.
