Higher colonic proliferation and tumor prevalence amongst azoxymethane treated A/J mice receiving fecal microbiota transplants from old mice compared to recipients of young mice [RNA-Seq]

Project description:Gut microbial dysbiosis can play a causal role of in colorectal cancer. Gut microbiota chnages with age and becomes moer pro-inflammatory. We sought to determine whether microbiota from Old donors promotes more tumor formation in recipients than meterial from young donors.

Gene expression of mouse intestine treated with azoxymethane and/or St. John's wort

Project description:The aim of this study was to examine the effects of dietary supplementation of St John’s wort extract on azoxymethane-induced colorectal carcinogenesis in mice. Microarray data showed atttenuation of NF-kB and ERK-mediated pathway in colon epithelium by St. Jone's wort suggesting that the anti-inflammatory effect is a possible cancer-preventing mechanism induced by St. Jone's wort. Gene expression will be compared between mice with the control vs. St. Jone's wort.

Human iPSC-derived GABAergic Interneuron Transplants Attenuate Neuropathic Pain

Project description:Neuropathic pain causes severe suffering and most patients are resilient to current therapies. A core element of neuropathic pain is the loss of inhibitory tone in the spinal cord. Previous studies have shown that foetal GABAergic neuron precursors can provide relief from pain. However, the source of these precursor cells and their multipotent status make them unsuitable for therapeutic use. Here we extend these findings by showing, for the first time, that spinally transplanted, terminally differentiated hiPSC-derived GABAergic (iGABAergic) neurons provide significant, long-term and safe relief from neuropathic pain induced by peripheral nerve injury in mice. Furthermore, iGABAergic Neuron transplants survive long term in the injured spinal cord and show evidence of synaptic integration. Together, this provides the proof in principle for the first viable GABAergic transplants to treat human neuropathic pain patients.

Molecular Phenotypes of Acute Kidney Injury in Kidney Transplants

Project description:Microarray analysis of human kidneys with acute kidney injury (AKI) has been limited because such kidneys are seldom biopsied. However, all kidney transplants experience AKI, and early kidney transplants without rejection are an excellent model for human AKI: they are screened to exclude chronic kidney disease, frequently biopsied, and have extensive follow-up. We used histopathology and microarrays to compare indication biopsies from 28 transplants with AKI to 11 pristine protocol biopsies of stable transplants. Kidneys with AKI showed increased expression of 394 injury-repair response associated transcripts, including many known epithelial injury molecules (e.g. ITGB6, LCN2), tissue remodeling molecules (e.g. VCAN), and inflammation molecules (S100A8, ITGB3). Many other genes also predict the phenotype, depending on statistical filtering rules, including AKI biomarkers as HAVCR1 and IL18. Most mouse orthologs of the top injury-repair transcripts were increased in published mouse AKI models. Pathway analysis of the injury-repair transcripts revealed similarities to cancer, development, and cell movement. The injury-repair transcript score AKI kidneys correlated with reduced function, future recovery, brain death, and need for dialysis, but not future graft loss. In contrast, histologic features of "acute tubular injury" did not correlate with function or with the molecular changes. Thus the injury-repair associated transcripts represent a massive coordinate injury-repair response of kidney parenchyma to AKI, similar to mouse AKI models, and provide an objective measure for assessing the severity of AKI in kidney biopsies and validation for the use of many AKI biomarkers.
