The clinical application of brain transplantation for treating Parkinson's disease (PD) is limited because it is difficult to obtain ideal donor cells. In this study, the tyrosine hydroxylase (TH) gene was introduced into NIH-3T3 cell line and the genetically modified cells reacted positively with TH antiserum and released L-dopa. These cells were implanted into the striatum of PD rats. 3,6,9,12 days after implantation, the average rate of the abnormal rotational behavior recovery was 52.6%, 68.4%, 63.2%, 44.7%, respectively. This result is considered to be potential for further clinical application.

Background: Allele-specific expression (ASE) analysis provides a nuanced view of cis-regulatory mechanisms affecting gene expression.
Results: An equine ASE analysis was performed, using integrated Iso-seq and short-read RNA sequencing data from four healthy Thoroughbreds (2 mares and 2 stallions) across 9 tissues from the Functional Annotation of Animal Genomes (FAANG) project. Allele expression was quantified by haplotypes from long-read data, with 42,900 allele expression events compared.

The detection of exons is an important area of research in genomic sequence analysis. Many signal-processing methods have been established successfully for detecting the exons based on their periodicity property. However, some improvement is still required to increase the identification accuracy of exons.

Chronic kidney disease (CKD) is defined by persistent abnormalities of kidney function or structure that have consequences for the health. A progressive decline of excretory kidney function has effects on body homeostasis. CKD is tightly associated with accelerated cardiovascular disease and severe infections, and with premature death.

Background: Whether adverse childhood experiences (ACEs) are associated with accelerated epigenetic aging over time among the Hispanic/Latino population remains unknown. This study examined the longitudinal association between ACEs and epigenetic age acceleration (EAA), as well as potential effect modifiers, among a sample of Hispanic/Latino adults.
Methods: We analyzed 960 Hispanic/Latino adults with DNA methylation (DNAm) profile data from two visits (approximately six years apart) sampled from the Hispanic Community Health Study/Study of Latinos (HCHS/SOL).

The genetic circuitry that encodes the developmental programme of mammals is regulated by transcription factors and chromatin modifiers. During early gestation, the three embryonic germ layers are established in a process termed gastrulation. The impact of deleterious mutations in chromatin modifiers such as the polycomb proteins manifests during gastrulation, leading to early developmental failure and lethality in mouse models.
