  • Patent number: 9550983
    Abstract: An isolated or a purified nucleic acid sequence for enhancing expression levels of a protein of interest, in 5? to 3? direction, comprises: a cytomegalovirus (CMV) promoter; an eEF-1 intron repeat (eEF-1 IR); and a regular sequence, which comprises: at least one tag element, a fixable linker sequence, wherein the fixable sequence is TEV sequence; and a multiple cloning site (MCS). By means of the array of the specific promoter and eEF-1 IR, the expression and purity of the recombinant protein could be enhanced; wherein eEF-1 IR can reduce the length of vector and assist RNA polymerase II transcription. Besides, TEV sequence of the fixable linker sequence of the regular sequence can remove a tag on recombinant protein; a specific target can be inserted into the multiple cloning site.

  • Patent number: 8912231
    Abstract: A method of treating airway remodeling symptom caused by phthalate esters, by providing a medication comprising: a ginger compound selected from one of (a) [6]-shogaol, (b) [6]-shogaol and [10]-gingerol, (c) [6]-shogaol and [8]-gingerol, and (d) [6]-shogaol and [6]-gingerol, and an acceptable carrier or excipient, which can relieve the airway remodeling symptoms of asthma, particularly to phthalate ester-induced airway remodeling, by suppressing the proliferation and migration of bronchial smooth muscle cells and reducing the instances of fatal asthma.

  • Publication number: 20100248253
    Abstract: A method for assessing a risk of suffering from a gout of a subject is provided. The method includes steps of obtaining a nucleotide sample from the subject; determining a genetic polymorphism of one of a Urate transporter 1 (URAT1) gene and an alpha-kinase 1 (ALPK1) gene in the nucleotide sample, wherein the genetic polymorphism is associated with an occurrence of the gout; and comparing the genetic polymorphism with a predetermined genetic polymorphism so as to assess the risk of suffering from the gout of the subject.

  • Publication number: 20090098056
    Abstract: The present invention relates to a method of identifying a human subject having an elevated risk of gout and/or hyperuricemia by detecting the occurrence of at least one SNP associated with an elevated risk of gout in an ALPK1 gene in a biological sample from the subject, or by determining the expression level of an ALPK1 gene in a biological sample from the subject. Also disclosed is an isolated nucleic acid molecule, its complement or gene variant comprising at least one of the polymorphisms identified herein to be associated with gout and/or hyperuricemia, a kit for performing a diagnostic test to identify a human subject having an elevated risk of gout and/or hyperuricemia, and a method of selecting or identifying a compound useful for treating gout and/or hyperuricemia.

  • Publication number: 20050170387
    Abstract: The present invention relates to a gout related gene locus located in the genomic region of about 90 cM to about 150 cM on chromosome 4, which region is flanked by genome markers D4S2361 and D4S1644. The genomic region can be used in a haplotype assay of the genome markers found in the region to determine whether a family member of a gout subject has the propensity to become inflicted with gout. The same genome markers can be used in a haplotype assay to determine whether a family member of a hyperuricemia subject has the propensity to become inflicted with hyperuricemia.
