Down Regulation of Osteocalcin Gene in Chickens Treated with Cadmium
Background: Cadmium is one of the heavy metals with harmful effects on different body organs and systems. The aim of this study was to investigate the harmful effects of cadmium, as a heavy metal, on the histological structure of bone and the expression of osteocalcin gene. Methods: Forty chickens were obtained, anesthetized and their femurs were surgically removed. The real time polymerase ch...
متن کاملRoles of Chromatin insulators in gene regulation and diseases
With advances in genetic science, the dynamic structure of eukaryotic genome is considered as basis of gene expression regulation. Long-distance communication between regulatory elements and target promoters is critical and the mechanisms responsible for this connection are just starting to emerge. Chromatin insulators are key determinants of proper gene regulation and precise organization of c...
متن کاملNutrition and Gene Regulation Symposium Introduction: Nutrition and Gene Regulation
Nutritional genomics is the study of nutrient-gene interactions and the effect these interactions have on health. It includes how diet affects the way genes are expressed, the effect of genes on how the body uses nutrients, and the effects of nutrients on molecular level processes in the body. It is an area of science that seeks to help people improve their health by studying how genes influenc...
متن کاملCombinatorial Gene Regulation Using Auto-Regulation
As many as 59% of the transcription factors in Escherichia coli regulate the transcription rate of their own genes. This suggests that auto-regulation has one or more important functions. Here, one possible function is studied. Often the transcription rate of an auto-regulator is also controlled by additional transcription factors. In these cases, the way the expression of the auto-regulator re...
متن کاملInferring gene regulation networks
A current challenge in system biology is to infer the regulation network of a family of p genes from a n-sample of microarrays, with n (much) smaller than p. Gaussian graphical models are simple models to describe these regulation networks. We propose a procedure that performs Gaussian graph estimation by model selection. We introduce a collection of candidate graphs and then select one of them...
