The 17-mer oligonucleotide probe homologous to the fragment of the gene for human erythrocyte differentiation factor erythropoietin was used to screen the human genomic library for this gene. Restriction analysis and partial sequencing of one of the identified clones have confirmed that the clone does contain the human erythropoietin gene. We are planning to use the cloned human erythropoietin gene for developing a stably transfected mammalian cell line that should secrete erythropoietin.

Defective Slc7a7 transport reduces erythropoietin compromising erythropoiesis.

Background: Lysinuric protein intolerance is a rare autosomal disorder caused by mutations in the Slc7a7 gene that lead to impaired transport of neutral and basic amino acids. The gold standard treatment for lysinuric protein intolerance involves a low-protein diet and citrulline supplementation. While this approach partially improves cationic amino acid plasma levels and alleviates some symptoms, long-term treatment is suggested to be detrimental and may lead to life-threatening complications characterized by a wide range of hematological and immunological abnormalities.

Blood transfusion plays a vital role in modern medicine, but frequent shortages occur. Ex vivo manufacturing of red blood cells (RBCs) from universal donor cells offers a potential solution, yet the high cost of recombinant cytokines remains a barrier. Erythropoietin (EPO) signaling is crucial for RBC development, and EPO is among the most expensive media components.

Background: Anemia is prevalent among pediatric patients diagnosed with end-stage kidney disease (ESKD). In addition, erythropoiesis-stimulating agents (ESA) and iron supplementation are considered the cornerstones in the management of anemia. However, a significant proportion of patients remain anemic.

A cost minimized immunoaffinity protocol was developed, which allows the direct purification of ERAs (urinary and recombinant human EPO, Darbepoetin, EPO-Fc, CERA) from human urine. The method applies magnetic beads and needs no covalent immobilization of the capture antibody. It requires only 10 mL of urine, 1 μg of anti-EPO antibody, and 25 μL of bead slurry.

Hereditary hemochromatosis occurs due to genetic mutations, namely, cysteine-to-tyrosine substitution at amino acid 282 (C282Y) and histidine-to-aspartic acid substitution at 63 (H63D) mutations. The role of H63D mutation in hemochromatosis is less clear, and its penetrance is low even in homozygotes. Therefore, iron overload in H63D heterozygotes is extremely rare and scarcely reported.
