The protective effect of heme oxygenase-1 (HO-1) expression in cardiovascular disease has been previously demonstrated using transgenic animal models in which HO-1 is constitutively overexpressed in the heart. However, the temporal requirements for protection by HO-1 induction relative to injury have not been investigated, but are essential to employ HO-1 as a therapeutic strategy in human cardiovascular disease states.

Retroviral vectors are versatile gene transfer vehicles widely used in basic research and gene therapy. Mutation of retroviral integrase converts these vectors into transient, integration-deficient gene delivery vehicles associated with a high degree of biosafety. We explored the option to use integration-deficient retroviral vectors to achieve transient ectopic expression of transcription factors, which is considered an important tool for induced cell fate conversion.

Peroxisome proliferator-activated receptors (PPARs) consist of three subtypes, each displaying distinctive tissue distribution. In general, the three PPAR subtypes exert overlapping function in transcriptional regulation of lipid metabolism. However, each PPAR subtype possesses distinctive functions in different tissues dependent on their expression abundance, endogenous ligands, and the PPAR coregulators in a specific tissue. Transgenesis is an invaluable technique in defining the in vivo function of a particular gene and its protein.

Proliferative retinopathy is a leading cause of blindness, including retinopathy of prematurity (ROP) in children and diabetic retinopathy in adults. Retinopathy is characterized by an initial phase of vessel loss, leading to tissue ischemia and hypoxia, followed by sight threatening pathologic neovascularization in the second phase. Previously we found that Sirtuin1 (Sirt1), a metabolically dependent protein deacetylase, regulates vascular regeneration in a mouse model of oxygen-induced proliferative retinopathy (OIR), as neuronal depletion of Sirt1 in retina worsens retinopathy.

BACKGROUND AND OBJECTIVES: It is well documented that the decrease of glucocorticoid receptor (GR) can lead to Yin-yang Deficiency Syndrome in the Traditional Chinese Medicine theory. Youguiyin a famous and traditional Chinese medicine is often used to treat Yang Deficiency Syndrome, but its mechanism of action and target remains unknown. We aimed to establish one cell model whose the GR gene had been decreased and observe the effect of the traditional Chinese medicine Youguiyin on GR gene expression at mRNA level.
