  • The authors suggested that the responsible locus encoded a trans-acting factor involved in the normal regulation of alpha-globin expression. (findzebra.com)
  • 1994. Expression of thyrotropin-releasing hormone receptors by adenovirus-mediated gene transfer reveals that thyrotropin-releasing hormone desensitization is cell specific. . (cornell.edu)
  • However, a profound variation in colony morphology, growth rate, BrdU incorporation, and relative abundance of gene expression in undifferentiated and differentiated states of the cell lines was observed. (biomedcentral.com)
  • The expression of skin color results from the interplay of several genes like tyrosinase which starts of the reaction by converting tyrosine to L-DOPA. (biologybard.com)
  • The HBB gene provides instructions for making a protein called beta-globin. (medlineplus.gov)
  • At least 1 commercial laboratory (Prevention Genetics, Marshfield, Wisconsin) was identified that offers testing for FSHD2 through sequencing of the SMCHD1 gene via bidirectional Sanger sequencing. (arkansasbluecross.com)
  • Prevention Genetics also offers testing for FSHD2 through next-generation sequencing of the SMCHD1 gene as part of a panel test for limb-girdle muscular dystrophy. (arkansasbluecross.com)
  • Thalassemia Intermedia There is the deficiency of beta globin production in the body which leads to significant illness. (athletesandinjuries.com)
