MODELLING RIBOFLAVIN TRANSPORTER DEFICIENCY (RTD) USING IPSC-DERIVED MODELS TO TEST GENE THERAPY EFFICACY
Riboflavin transporter deficiency syndrome (RTD) is a rare childhood-onset neurodegenerative disorder caused by mutations in SLC52A2 and SLC52A3 genes, encoding the riboflavin (RF) transporters RFVT2 and RFVT3. In the present study we focused on RTD Type 2, which is due to variants in SLC52A2 gene. …

Ablation of Retbindin, the Riboflavin Binding Protein, Exacerbates Retinal Degenerative Phenotypes in Mouse Models of Human Retinal Diseases
Retbindin (Rtbdn) is a retina-specific, riboflavin binding protein, expressed only by the rod photoreceptor cells. Riboflavin is the precursor of flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD) which are essential co-factors for enzymes involved in wide-range of metabolic …

Chemical evidence of the quantitative thiamine and riboflavin requirements of the rat during pregnancy and the development of the fetus
… to determine more accurately the quantitative riboflavin needs of the rat during reproduction. One procedure, that of determining the deposition of riboflavin in the developing fetal and placental tissues at several intervals during pregnancy, has revealed a very rapid increase in the …

Biofilm formation by Shewanella oneidensis MR-1 towards fundamental understanding of anode respiring communities
… fluxes and the subsequent metabolic response of riboflavin production by S. oneidensis. It was also observed that riboflavin production occurred in micro-aerobic and anaerobic environments at the onset of carbon limitation but no riboflavin was detectable in anaerobic cultures. As riboflavin has …
