The dihydrofolate reductase-deficient Chinese hamster ovary (CHO) cell line DG44 is the dominant mammalian host for recombinant protein manufacturing, in large part because of the availability of a well-characterized genetic selection and amplification sys ...
The molecular mechanisms underlying gametocytogenesis in malaria parasites are not understood. Plasmodium falciparum cdc2-related kinase 1 (pfcrk-1), a gene that is expressed predominantly in gametocytes, bears homology to the PITSLRE subfamily of cyclin-d ...
Pigment cells of mammals originate from two different lineages: melanocytes arise from the neural crest, whereas cells of the retinal pigment epithelium (RPE) originate from the optic cup of the developing forebrain. Previous studies have suggested that pi ...
Protein-DNA interactions (PDIs) between transcription factors (TFs) and their target genes form the backbone of transcription regulatory networks. Such PDIs can be identified with either a TF or a gene as a starting point. The Gateway-compatible yeast one- ...
BACKGROUND: Ex vivo liver gene therapy provides an attractive alternative to orthotopic liver transplantation for the treatment of liver diseases. We previously reported a protocol in which human primary hepatocytes are highly transduced in Suspension with ...
Analysis of genetically engineered mice is crucial for our understanding of the in vivo function of genes and proteins in the whole organism. This includes inactivation of a gene or the generation of specific mutations. The development of knockout and tran ...
AIMS/HYPOTHESIS: We examined a clinical model of ex vivo transdifferentiation of primary adult hepatocytes to insulin-secreting cells for the treatment of type 1 diabetes. MATERIALS AND METHODS: Isolated rat hepatocytes were transduced in primary culture w ...
Dopamine-induced changes in striatal gene expression are thought to play an important role in drug addiction and compulsive behaviour. In this study we report that dopamine induces the expression of the transcription factor CCAAT/Enhancer Binding Protein b ...
Lipid membranes were studied by infrared scanning near-field optical microscopy at several wavelengths and by x-ray reflectivity. Together with the x-ray data, the optical images indicate the formation of locally ordered multiple bilayers, and the topograp ...
RNA interference (RNAi) has emerged as a powerful tool to downregulate the expression of specific genes. Drug-inducible systems allowing for conditional RNAi that offer the unique potential to modulate expression of virtually any endogenous gene in the cel ...
