  • In this region, six major classes of retinal neurons differentiate and form neural circuits responsible for vision. (oist.jp)
  • In vitro assays were developed to validate the variants identified (fibroblast assay, induced pluripotent stem cell [iPSC] derived retinal organoids, and a dynein motility assay). (nature.com)
  • Analysis of retinal organoids showed that this new transcript expression increased with organoid differentiation. (nature.com)
  • Expression of the canine gene transcripts and protein was analyzed by Northern and Western blotting and immunocytochemistry. (upenn.edu)
  • In this study, we differentiated gene-corrected RP-hiPSCs into RPE and found that these cells had recovered both wild-type MERTK protein expression and the lost phagocytosis of fluorescently-labeled photoreceptor outer segments observed in uncorrected RP-hiPSC-RPE. (bvsalud.org)
  • In some cases, misfolding of the protein results in a loss of its usual function. (wikipedia.org)
  • The SLC3A1 gene codes for a protein that allows the kidneys to transport cystine and other amino acids from the urine. (doodlesweethearts.com)
  • Variants in the SMCHD1 gene on chromosome 18, which encodes a protein known as structural maintenance of chromosomes flexible hinge domain containing 1, have been associated with FSHD2. (arkansasbluecross.com)
