Transcription of Genes Is Significantly Increased during Neuronal Differentiation of iPSCs Derived from Patients with Parkinson's Disease.

Parkinson's disease (PD) is the most serious movement disorder, but the actual cause of this disease is still unknown. Induced pluripotent stem cell-derived neural cultures from PD patients carry the potential for experimental modeling of underlying molecular events. We analyzed the RNA-seq data of iPSC-derived neural precursor cells (NPCs) and terminally differentiated neurons (TDNs) from healthy donors (HD) and PD patients with mutations in published previously.

Activation of Embryonic Gene Transcription in Neural Precursor Cells Derived from the Induced Pluripotent Stem Cells of the Patients with Parkinson's Disease.

Parkinson's disease (PD) is one of the most common neurodegenerative diseases in the world. Despite numerous studies, the causes of this pathology remain completely unknown. This is, among other things, due to the difficulty of obtaining biological material for analysis.

Transcriptome datasets of neural progenitors and neurons differentiated from induced pluripotent stem cells of healthy donors and Parkinson's disease patients with mutations in the gene.

Parkinson's disease (PD) is a complex systemic disorder caused by neurodegenerative processes in the brain that are mainly characterized by progressive loss of dopaminergic neurons in the substantia nigra. About 10% of PD cases have been linked to specific gene mutations (Zafar and Yaddanapudi, 2022) including the gene that encodes a RING domain-containing E3 ubiquitin ligase Parkin. PD-Parkin patients have a younger onset, longer disease duration, and more severe clinical symptoms in comparison to PD patients with unknown causative PD mutations (Zhou et al.

Secondary structure-stretched forms of long intron RNA products from the view point of initiation of chromosome homologs somatic pairing.

In different types of chromosome pairing (meiotic, somatic, and sister chromatids pairing) initiation stages are less elucidated. In somatic homolog pairing initiation, the long intron RNA products interference may play the essential role. The strongest somatic pairing in Drosophila melanogaster 28B1-B2 locus and its enrichment by long bi-directional transcripts prone us to analyze the pre-mRNA secondary structures.

Large-scale periodicity of nucleosome positioning signal in pericentric regions of chromosomes (Drosophila melanogaster).

Nucleosome positioning signal (NPS) in heterochromatin is not uniform. We suggest the analysis of its heterogeneity by correlation with periodic function (analog of Furrier analysis). It was established the periodical repetition of the nucleosome clusters of large size in pericentric regions in a discontinuous manner.
