The transcription factor c-jun is selectively expressed by non-myelinating Schwann cells in normal peripheral nerve, and be "denervated," previously myelinatng Schwann cells, after axotomy. When axons regenerate into the distal nerve-stump, the expression of c-jun declines as Schwann cells remyelinate axons. Treating cultured Schwann cells with forskolin, a(More)
Recent studies indicate that interactions between leukemia cells and the bone marrow (BM) microenvironment promote leukemia cell survival and confer resistance to anti-leukemic drugs. There is evidence that BM microenvironment contains hypoxic areas that confer survival advantage to hematopoietic cells. In the present study we investigated whether hypoxia(More)
CXCR4, the receptor for stromal-derived factor-1, is reportedly involved in breast carcinogenesis. However, the mechanisms through which CXCR4 contributes to breast cancer cell growth and metastases are poorly understood. In this study, we examined the putative in vitro and in vivo anti-cancer effects of the specific CXCR4 inhibitor AMD3465. Here, we report(More)
BACKGROUND Acute myeloid leukemia (AML) therapy has limited long-term efficacy because patients frequently develop disease relapse because of the inability of standard chemotherapeutic agents to target AML stem/progenitor cells. Here, we identify deregulated apoptotic components in AML stem/progenitor cells and investigate the individual and combinatorial(More)
Although a number of genetic defects in the P0, peripheral myelin protein-22, and connexin-32 genes recently were shown to cause the demyelinating forms of Charcot-Marie-Tooth disease, there is yet no effective treatment for these patients. Recent studies showed that replication defective adenoviral vectors can efficiently introduce genes into muscle,(More)

BACKGROUND/OBJECTIVES Prior studies have demonstrated that both the skin surface pH and epidermal permeability barrier function vary with skin pigmentation types. Although melanin deficiency is the main feature of vitiligo, alterations in cutaneous biophysical properties in vitiligo have not yet been well defined. In the present study, stratum corneum (SC)(More)
A probe for the 5' end of the Duchenne muscular dystrophy (DMD) gene was used to study expression of the gene in normal human muscle, myogenic cell cultures, and muscle from patients with DMD. Expression was found in RNA from normal fetal muscle, adult cardiac and skeletal muscle, and cultured muscle after myoblast fusion. In DMD muscle, expression of this(More)
LIM domain kinase 1 (LIMK1), an actin-binding kinase, can phosphorylate and inactivate its substrates, and can regulate long-term memory and synaptic plasticity. Both β-amyloid precursor protein (App) and presenilin (PS) are functional degeneration factors during early neuronal development, and are considered as potential factors that contribute to the(More)
In this paper, we report a robust, efficient, and automatic method for matching infrared tracked markers for human motion analysis in computer-aided physical therapy applications. The challenges of this task stem from non-rigid marker motion, occlusion, and timing requirements. To overcome these difficulties , we use pair-wise distance constraints for(More)
