Abstract: Provided is a fusion protein, which comprises human fibroblast growth factor 21 and glucagon-lihe-peptide-1 or its analogs. Also provided is the medicament composition comprising the fusion protein, which can be used for treating or preventing obesity, diabetes, hyperglycemia and hyperlipidemia etc.
摘要:
Detection of mutations associated with hereditary diseases is complicated by the diploid nature of mammalian cells. Mutations present in one allele are often masked by the wild-type sequence of the other allele. Individual alleles can be isolated from every chromosome within somatic cell hybrids generated from a single fusion. Nucleic acids from the hybrids can be analyzed for mutations in an unambiguous manner. This approach was used to detect two cancer-causing mutations that had previously defied genetic diagnosis. One of the families studied, Warthin Family G, was the first kindred with a hereditary colon cancer syndrome described in the biomedical literature.

Methods for reprogramming and optional genetic modification of cells are provided. A pluripotent genome is obtained from a differentiated genome by fusing a pluripotent cell with a differentiated cell in the presence of Nanog or a MEK inhibitor. A cell is genetically modified by providing first and second cells, each containing chromosomes, fusing the first cell and the second cell, and culturing the fused cell so as to obtain a diploid cell containing at least one chromosome from the first cell and at least one chromosome form the second cell. A method of cell fusion comprises fusing a first cell and a second cell in the presence of Nanog or a MEK inhibitor. Cells obtained thereby and their uses are also described.
摘要:
The present invention describes methods and processes for the production of proteins, particularly glycoproteins, by animal cell or mammalian cell culture, preferably, but not limited to, fed-batch cell cultures. In one aspect, the methods comprise at least two temperature shifts performed during the culturing period, in which the temperature is lower at the end of the culturing period than at the time of initial cell culture. Throughout their duration, the culturing processes of the invention involving two or more downward shifts in temperature sustain a high viability of the cultured cells, and can yield an increased end titer of protein product, and a high quality of protein product, as determined, e.g., by sialic acid content of the produced protein. In another aspect, the methods comprise the delayed addition of polyanionic compound during the culturing period. The delayed addition of polyanionic compound sustains a high viability of the cultured cells, and can extend the growth phase, delay the onset of the death phase, and arrest the death phase.
