(Submitter supplied) The mechanical effect of raised intraocular pressure is a recognised stimulus for optic neuropathy in primary open angle glaucoma (POAG). Characteristic extra-cellular matrix (ECM) remodelling accompanies axonal damage in the lamina cribrosa (LC) of the optic nerve head in POAG. Glial cells in the lamina cribrosa may play a role in this process but the precise cellular responses to mechanical forces in this region are unknown. more...

(Submitter supplied) Background and Purpose Aneurysmal subarachnoid hemorrhage, almost always from saccular intracranial aneurysm (sIA), is a devastating form of stroke that affects working age population. Cellular and molecular mechanisms predisposing to the rupture of the sIA wall are largely unknown. Such knowledge would facilitate the design of novel diagnostic tools and therapies for the sIA disease. Methods We compared the whole genome expression profile of eleven ruptured sIA wall samples, resected at a median of 15 hours after rupture, to that of eight unruptured ones. more...

(Submitter supplied) Purpose: The morphology of the RPE shows minimal change as the neural retina and choriocapillaris differentiate. Nonetheless, initial studies of barrier-related proteins suggest extensive remodeling of the RPE in response to this changing environment. A genomic approach was used to investigate the extent of this remodeling. Methods: RPE was isolated from E7, E10, E14 and E18 chick embryos and total RNA extracted for probing the entire genome on Affymetrix microarray chips. more...

(Submitter supplied) Gene expression information is useful in prioritizing candidate genes in linkage intervals. The data can also identify pathways involved in the pathophysiology of disease. We used microarrays to identify which genes are expressed in either intracranial arteries (control) or in intracranial aneurysms (case), and can therefore contribute to the disease phenotypes. We used microarrays to identify the pathway membership of expressed genes and the overrepresentation of pathways with expressed genes in the known linkage intervals for intracranial aneurysms. more...

(Submitter supplied) Develop of the heart during perinatal period must involve the differentially expression of a myriad of genes. We can think about the developmental events of heart formation in the context of genetic networks. However the knowledge of the genetic basis in governing and regulating of this development is still partial and scattered; an overall elucidation of the differential expressed genes blueprint before and after birth has never been proposed. more...

(Submitter supplied) Prolonged use of glucocorticoids can lead to the formation of a cataract, however the mechanism is not known. We recently reported the presence of the functional glucocorticoid receptor in immortalized cultured mammalian lens epithelial cells (Gupta & Wagner, Invest Ophthalmol Vis Sci 2003), but the short term biological effect of glucocorticoid action in lens epithelial cells is not known. This study seeks to examine glucocorticoid induced changes in global gene expression in LECs. more...

(Submitter supplied) Studies using mice with beta4 nicotinic acetylcholine receptor (nAChR) subunit deficiency (beta4-/- mice) helped reveal the roles of this subunit in bradycardiac response to vagal stimulation, nicotine-induced seizure activity and anxiety. In order to identify genes that might be related to beta4-containing nAChRs activity, we compared the mRNA expression profiles of brains from beta4-/- and wild-type mice using Affymetrix U74Avr2 microarray. more...

(Submitter supplied) Background and Purpose—Analyzing genes involved in development and rupture of intracranial aneurysms can enhance knowledge about the pathogenesis of aneurysms, and identify new treatment strategies. We compared gene expression between ruptured and unruptured aneurysms and control intracranial arteries. Methods—We determined expression levels with RNA sequencing. Applying a multivariate negative binomial model, we identified genes that were differentially expressed between 44 aneurysms and 16 control arteries, and between 22 ruptured and 21 unruptured aneurysms. more...

(Submitter supplied) Mammalian lung development is a complex morphogenetic process, which initiates near mid-gestation and continues through early postnatal life. The lung arises as two lateral buds that emerge from the ventral foregut endoderm at ~ 9 days after fertilization (in mouse) and undergo numerous rounds of dichotomous branching to form the bronchial tree. This stage of development is referred to as the pseudoglandular phase, histologically characterized by loose mesenchyme surrounding undifferentiated epithelial tubes. more...
