Article Abstract

Pulmonary arterial hypertension (PAH) is a rare but severe illness associated with mutations in the PTGIS gene. The single nucleotide variants may lead to the impairment of the endothelial cells functions, resulting in proliferation of the smooth muscle cells and occlusion of the pulmonary arterioles. We derived an induced pluripotent cell line from a PAH patient with heterozygous PTGIS c.755 G > A, which could serve as a unique model to understand the pathogenesis of PAH.

Understanding the genetic causes of diseases affecting pancreatic β cells and neurons can give insights into pathways essential for both cell types. Microcephaly, epilepsy and diabetes syndrome (MEDS) is a congenital disorder with two known aetiological genes, IER3IP1 and YIPF5. Both genes encode proteins involved in endoplasmic reticulum (ER) to Golgi trafficking.

Mutations in Delta Like Non-Canonical Notch Ligand 1 (DLK1), a paternally expressed imprinted gene, underlie central precocious puberty (CPP), yet the mechanism remains unclear. To test the hypothesis that DLK1 plays a role in gonadotropin releasing hormone (GnRH) neuron ontogeny, 75 base pairs were deleted in both alleles of DLK1 exon 3 with CRISPR-Cas9 in human pluripotent stem cells (hPSCs). This line, exhibiting More than 80% loss of DLK1 protein, was differentiated into GnRH neurons by dual SMAD inhibition (dSMADi), FGF8 treatment and Notch inhibition, as previously described, however, it did not exhibit accelerated GNRH1 expression.

Introduction: Hematopoietic stem cell transplantation (HSCT) is a promising treatment option for hematological malignancies. Despite its curative potential, it faces clinical challenges, including relapse and graft-versus-host disease (GVHD). Systemic toxicity due to chemotherapy is a significant problem in patients with hematological malignancies.

Chromatin dynamics play a crucial role in cellular differentiation, yet tools for studying global chromatin mobility in living cells remain limited. Here, a novel probe is developeded for the metabolic labeling of chromatin and tracking its mobility during neural differentiation. The labeling system utilizes a newly developed silicon rhodamine-conjugated deoxycytidine triphosphate (dCTP).

Neurodegenerative diseases and spinal cord injuries (SCI) pose a significant burden on the healthcare system globally. Diseases such as Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and Huntington's disease precipitate cognitive, motor, and behavioral deficits. Parallelly, spinal cord injuries produce sensory and motor deficits, which are burdensome psychologically, socially, and economically.
