Results from a recent study that presented evidence suggesting a lack of cytoplasmic inheritance of lactation traits were reexamined using a model that included effects of additive genotype, cytoplasmic genotype, their interaction, and maternal influences. Under this model, equivalent estimates of heritability from daughter-dam and grand-daughter-grand-dam regression that exceed those from pate...
Background: The potential applications of a simplified method of somatic cell nuclear transfer (SCNT) that is improved in both efficiency and throughput is considerable. Technically, a major step of SCNT is to produce large pools of enucleated oocytes (cytoplasts) efficiently, a process that requires considerable micromanipulation skill and expensive equipment. Here, we have devel oped an efficient...
BACKGROUND Hepatic gene transfer, in particular using adeno-associated viral (AAV) vectors, has been shown to induce immune tolerance to several protein antigens. This approach has been exploited in animal models of inherited protein deficiency for systemic delivery of therapeutic proteins. Adequate levels of transgene expression in hepatocytes induce a suppressive T cell response, thereby prom...
In well-differentiated human airway epithelia, the coxsackie B and adenovirus type 2 and 5 receptor (CAR) resides primarily on the basolateral membrane. This location may explain the observation that gene transfer is inefficient when adenovirus vectors are applied to the apical surface. To further test this hypothesis and to investigate requirements and barriers to apical gene transfer to diffe...
