Angiogenesis-Related Genes in Endothelial Progenitor Cells May Be Involved in Sickle Cell Stroke. | LitMetric

AI Article Synopsis

Article Abstract

Background The clinical aspects of sickle cell anemia (SCA) are heterogeneous, and different patients may present significantly different clinical evolutions. Almost all organs can be affected, particularly the central nervous system. Transient ischemic events, infarcts, and cerebral hemorrhage can be observed and affect ≈25% of the patients with SCA. Differences in the expression of molecules produced by endothelial cells may be associated with the clinical heterogeneity of patients affected by vascular diseases. In this study, we investigated the differential expression of genes involved in endothelial cell biology in SCA patients with and without stroke. Methods and Results Endothelial progenitor cells from 4 SCA patients with stroke and 6 SCA patients without stroke were evaluated through the polymerase chain reaction array technique. The analysis of gene expression profiling identified 29 differentially expressed genes. Eleven of these genes were upregulated, and most were associated with angiogenesis (55%), inflammatory response (18%), and coagulation (18%) pathways. Downregulated expression was observed in 18 genes, with the majority associated with angiogenesis (28%), apoptosis (28%), and cell adhesion (22%) pathways. Remarkable overexpression of the (matrix metalloproteinase 1) gene in the endothelial progenitor cells of all SCA patients with stroke (fold change: 204.64; =0.0004) was observed. Conclusions Our results strongly suggest that angiogenesis is an important process in sickle cell stroke, and differences in the gene expression profile of endothelial cell biology, especially , may be related to stroke in SCA patients.

Background: Spinocerebellar ataxias (SCAs) encompass a wide spectrum of inherited neurodegenerative diseases, primarily characterized by pathological changes in the cerebellum, spinal cord, and brainstem degeneration. Autosomal dominant spinocerebellar ataxia type 48 (SCA48) is a newly identified subtype of SCA, marked by early-onset ataxia and cognitive impairment, and is associated with mutations in the STIP1 homology and U-box-containing protein 1 (STUB1) gene. The STUB1 gene encodes the protein CHIP (C-terminus of HSC70-interacting protein) which functions as E3 ubiquitin ligase and is crucial to the development of neural systems.

Neurodegeneration refers to the gradual loss of neurons and extensive changes in glial cells like tau inclusions in astrocytes and oligodendrocytes, α-synuclein inclusions in oligodendrocytes and SOD1 aggregates in astrocytes along with deterioration in the motor, cognition, learning, and behavior. Common neurodegenerative disorders are Alzheimer's disease (AD), Parkinson's disease (PD), amyotrophic lateral sclerosis (ALS), Huntington's disease (HD), spinocerebellar ataxia (SCA), and supranuclear palsy. There is a lack of effective treatment for neurodegenerative diseases, and scientists are putting their efforts into developing therapies against them.

Swept-source optical coherence tomography assessment of Schlemm's canal after phacoemulsification with goniosynechialysis in Chinese patients with primary angle-closure glaucoma.

Department of Ophthalmology & Visual Science, Eye, Ear, Nose, and Throat Hospital, Shanghai Medical College, Fudan University, Shanghai, China.

Background: Primary angle-closure glaucoma (PACG) is a leading cause of irreversible blindness worldwide. However, the features of the morphology of Schlemm's canal (SC) in PACG eyes after phacoemulsification with goniosynechialysis (phaco-GSL) surgery are still unknown. This study aimed to evaluate changes in the SC in Chinese patients with PACG after phaco-GSL using swept-source optical coherence tomography (SS-OCT).

Sex chromosome aneuploidies (SCA) such as Turner, Klinefelter, Jacobs, and Trisomy X syndromes are prevalent genetic disorders with well-established phenotypes. Challenges persist, however, in determining the need for further genetic evaluation in cases of affected individuals exhibiting atypical symptoms. The present study retrospectively examined 54 pediatric patients with an SCA diagnosis at a single institution between January 2015 and December 2023.
