Affymetrix Rat Gene 1.0 ST Array (ragene10st)
Description
The global prevalence of obesity is increasing across age and gender. The rising burden of obesity in young people contributes to the early emergence of type 2 diabetes. Having one parent obese is an independent risk factor for childhood obesity. While the detrimental impact of diet-induced maternal obesity on offspring is well established, the extent of the contribution of obese fathers is unclear, as is the role of non-genetic factors in the casual pathway. Here we show that paternal high fat diet exposure programmed -cell dysfunction in their F1 female offspring. Chronic high fat diet consumption in Sprague Dawley fathers led to increased body weight, adiposity, impaired glucose tolerance and insulin sensitivity. Relative to controls, their female offspring had lower body weight at day-1, increased pubertal growth rate, impaired insulin secretion and glucose tolerance, in the absence of obesity or increased adiposity. Paternal high fat diet altered the expression of 211 pancreatic islet genes in adult female offspring (P < 0.001); genes belonged to 8 functional clusters, including calcium ion binding, primary metabolic processes and ATP binding, and organ/system development. Broader KEGG pathway analysis of 2014 genes differentially expressed at the P < 0.01 level further demonstrated involvement of insulin and calcium signaling, and MAPK pathways. This is the first reported study in mammals describing non-genetic, intergenerational transmission of metabolic sequelae of high fat diet from father to offspring. These findings support a role of fathers in metabolic programming of offspring and form a framework for further studies.

Description
Differentiation of human skeletal stem cells (hMSC) into osteoblasts is regulated by a few well described transcription factors. Our study used clustering and gene expression data to identify a novel transcription factor. ZNF25, which we showed is involved in osteoblast differentiation.

Description
We surveyed the transcriptomes of the whole heart and whole gastrocnemius muscle taken from two different types of Balb/c-DBAj hybrid mice (10-11 weeks old). The colon cancer bearing mice are called C26. The NTB are the non-tumor bearing mice.

Paternal high fat diet was observed to alter gene expression of pancreatic islet genes in adult female offspring (P < 0.001); affected functional clusters includes calcium ion binding, insulin, apoptosis, Wnt and cell cycle organ/system development. This is the first reported study in mammals describing non-genetic, intergenerational transmission of metabolic sequelae of high fat diet from father to offspring. These findings support a role of fathers in metabolic programming of offspring and form a framework for further studies.

Description
Activated pancreatic stellate cells produce the fibrotic matrix in chronic pancreatitis and pancreatic cancer. In vitro protocols examining PSC biology have usually involved PSCs cultured on plastic, a non-physiological surface. However, PSCs cultured on physiological matrices e.g. MatrigelTM (normal basement membrane) and collagen (fibrotic pancreas), may have distinctly different behaviours compared to cells cultured on plastic. Therefore, we aimed to compare PSC gene expression after culture on plastic, MatrigelTM and collagen I.

BACKGROUND: Appendicitis followed by appendectomy (AA) at a young age protects against later inflammatory bowel disease (IBD). Using a novel murine appendicitis model we earlier demonstrated that AA proffered significant protection against subsequent experimental colitis.
