Whole-genome sequencing holds the key to the success of gene-targeted therapies.

Rare genetic disorders affect as many as 3%-5% of all babies born. Approximately 10,000 such disorders have been identified or hypothesized to exist. Treatment is supportive except in a limited number of instances where specific therapies exist.

Starting the conversation on gene therapy for phenylketonuria: Current perspectives of patients, caregivers, and advocates.

Phenylketonuria (PKU) is a rare genetic condition caused by inborn error(s) in the gene for the enzyme phenylalanine hydroxylase. Resulting loss of phenylalanine (Phe) metabolism requires strict dietary therapy and/or medication to prevent toxic accumulation of Phe. Novel investigational therapies, including gene therapies that aim to address underlying causes of PKU, are now entering clinical trials.

Automated measurement of cell motility and proliferation.

Background: Time-lapse microscopic imaging provides a powerful approach for following changes in cell phenotype over time. Visible responses of whole cells can yield insight into functional changes that underlie physiological processes in health and disease. For example, features of cell motility accompany molecular changes that are central to the immune response, to carcinogenesis and metastasis, to wound healing and tissue regeneration, and to the myriad developmental processes that generate an organism.

In vitro and in vivo effects of an alpha3 neuronal nicotinic acetylcholine receptor antisense oligonucleotide.

In the mammalian central nervous system (CNS), a family of alpha and beta subunits (alpha2-7, beta2-4) assemble to form both hetero- and homopentameric neuronal nicotinic acetylcholine receptors (nAChRs). In contrast to alpha4beta2 and alpha7, the predominant brain subtypes, far less is known regarding the functional expression and significance of alpha3-containing nAChRs in the CNS. In trying to better understand the role alpha3 in the CNS, an antisense knockdown strategy was utilized in the present studies.

Identification of a functional link for the p53 tumor suppressor protein in dexamethasone-induced growth suppression.

Serine/threonine phosphatase 5 (PP5) can act as a suppresser of p53-dependent growth suppression and has been reported to associate with several proteins, including the glucocorticoid receptor/heat-shock protein-90 complex. Still, the physiological/pathological roles of PP5 are unclear. To characterize the relationship of PP5, glucocorticoid receptor activation and p53, here we describe the development of chimeric antisense oligonucleotides that potently inhibit human p53 expression.
