View SamplesIntervertebral disc degeneration is an important contributor to chronic low back pain. While a wide spectrum of clinically relevant degenerative disc phenotypes have been observed during aging, their molecular underpinning have not been established.
Comparison of inbred mouse strains shows diverse phenotypic outcomes of intervertebral disc aging.

View SamplesIn this study we analyzed the effects of lead-exposure up hippocampal gene expression in males and females exposed to 0ppm, 250ppm and 750ppm lead during two different developmental periods, perinatal (in utero through to weaning at PND21) and postnatal (PND0-PND45), across three strains (Fischer, Long Evans and Sprague Dawley). All tissue was taken at PND 55. We used affymetrix Rat Gene 1.0ST arrays to obtain global gene expression data from each animal, with a group size of 4 for all conditions (Total number of Arrays = 119)

View SamplesIn this study, we analyzed the effects of chronic alcohol consumption on liver repair and regeneration after partial hepatectomy (PHx). Rats were fed a liquid diet containing 36% of total calories derived from ethanol for 5 weeks; corresponding pair-fed calorie-matched controls were fed diets in which ethanol calories were replaced either by carbohydrate or by fat. After 5 weeks, rats were subjected to 70% PHx and liver samples were collected at 1, 6 and 24h after the surgery. The excised liver samples at t=0 served as within-animal controls. We used Affymetrix Rat Gene 1.0 ST arrays to obtain global gene expression data from each liver sample (n=4 replicate rats, 72 arrays total).
Chronic ethanol feeding enhances miR-21 induction during liver regeneration while inhibiting proliferation in rats.

View SamplesDuctal carcinoma in situ (DCIS) is a precursor lesion that can give rise to invasive breast cancer (IBC). It has been proposed that both the nature of the lesion and the tumor microenvironment play key roles in progression to IBC. Here, laser capture microdissected tissue samples from epithelium and stroma in normal breast, pure DCIS, and pure IBC were employed to define key gene expression profiles associated with disease progression.
Progression of ductal carcinoma in situ to invasive breast cancer is associated with gene expression programs of EMT and myoepithelia.

View SamplesCyclin D1b is a splice variant of the cell cycle regulator Cyclin D1 and is known to harbor divergent and highly oncogenic functions in human disease. While Cyclin D1b is induced during disease progression in many cancer types, the mechanisms underlying Cyclin D1b function remain poorly understood. Herein, models of human disease were utilized to resolve the downstream pathways requisite for the pro-tumorigenic functions of Cyclin D1b. Specifically, it was shown that Cyclin D1b modulates the expression of a large transcriptional network that cooperates with AR signaling to enhance tumor cell growth and invasive potential. Notably, Cyclin D1b promoted AR-dependent activation of genes associated with metastatic phenotypes. Further exploration determined that transcriptional induction of SNAI2 (Slug) was essential for Cyclin D1b- mediated proliferative and invasive properties, implicating Slug as a critical driver of disease progression. Importantly, Cyclin D1b expression highly correlated with that of Slug in clinical samples of advanced disease. Further, in vivo analyses provided strong evidence that Slug enhances both tumor growth and homing to distal soft tissues. Collectively, these findings reveal the underpinning mechanisms behind the pro-tumorigenic functions of Cyclin D1b, and demonstrate that the convergence of the Cyclin D1b-AR and Slug pathways results in the activation of processes critical for the promotion of lethal tumor phenotypes.
