Generation of two isogenic sickle cell disease induced pluripotent stem cell lines from testicular fibroblasts.

Curative bone marrow transplantation (BMT) therapies for sickle cell disease (SCD) can cause infertility. The Fertility Preservation Program (FPP) in Pittsburgh cryopreserves testicular tissues for SCD patients prior to BMT in anticipation that those tissues can be thawed in the future and matured to produce sperm. Here, we generated and validated two isogenic patient-derived induced pluripotent stem cell (iPSC) lines from testicular biopsy fibroblasts of a 12-year-old SCD patient.

Antiviral Properties of the LSD1 Inhibitor SP-2509.

Lysine-specific demethylase 1 (LSD1) targets cellular proteins, including histone H3, p53, E2F, and Dnmt1, and is involved in the regulation of gene expression, DNA replication, the cell cycle, and the DNA damage response. LSD1 catalyzes demethylation of histone H3K9 associated with herpes simplex virus 1 (HSV-1) immediate early (IE) promoters and is necessary for IE gene expression, viral DNA replication, and reactivation from latency. We previously found that LSD1 associates with HSV-1 replication forks and replicating viral DNA, suggesting that it may play a direct role in viral replication or coupled processes.
