Article Synopsis
  • - Land-use change significantly contributes to biodiversity loss in Africa, yet there has been limited research on future projections due to uncertainties; this study aims to fill that gap by analyzing various land-use scenarios from 2021 to 2100.
  • - The research uses 2020 observational land-use data to evaluate future changes across seven Shared Socioeconomic Pathways (SSP) scenarios, finding strong correlations (0.89) between current and projected land uses.
  • - Projected outcomes indicate a decrease in barren and forest land, while cropland, grassland, and urban areas will likely expand significantly, raising concerns about biodiversity loss and ecosystem health in the region.

Background: Whole-exome sequencing (WES) significantly improves the diagnosis of the etiology of fetal structural anomalies. This study aims to evaluate the diagnostic value of prenatal WES and to investigate the pathogenic variants in structurally abnormal fetuses.

Methods: We recruited 144 fetuses with structural anomalies between 14 and 2020 and 15 December 2021 in the study.

Background: α-thalassemia is an inherited blood disorder caused by variants in the α-globin gene cluster. Identification of the pathogenic α-globin gene variants is important for the diagnosis and management of thalassemia.

Methods: Two suspected families from Xiantao, Hubei Province were recruited in this study.

To demonstrate the feasibility of haplotype-based noninvasive prenatal diagnosis of Facioscapulohumeral Muscular Dystrophy type 1 (FSHD1). Bionano optical mapping was used to identify the D4Z4 structural variation of the genomic DNA sample from the proband affected with FSHD1. In addition, based on the technique of next generation sequencing, the pathogenic haplotype was determined by using trio strategy through genotyping his parents, and also fetal inheritance of paternal haplotypes was then deduced using the Hidden Markov Model.

There is no information concerning the prevalence of thalassemia among pregnant women in Hubei Province currently. This study is aimed to explore the prevalence of α- and β-thalassemia genotypes among pregnant women in Hubei Province, and to explore the clinically applicable screening approach, as well as to investigate the pregnancy outcomes of α- and β-thalassemia carriers.Pregnant participants were recruited from 4 hospitals for the screening of α- and β-thalassemia mutations in Hubei Province.

Objective: To explore the genotype mutation characteristics of patients with glucose-6-phosphate dehydrogenase(G6PD) deficiency in Wuhan.

Methods: A total of 1 321 neonates with positive screening and outpatients were received G6PD mutation detection, 12 kinds of common G6PD mutation in Chinese people was detected by using multicolor melting curve analysis (MMCA) method, for those with negative results, the enzyme activity and clinical information were analyzed, sequencing was recommended after informed consent when it is necessary.

Results: Among 1321 patients, a total of 768 mutations were detected out, with a detection rate of 58.

In this article, we found that 20-Hydroxyeicosatetraenoic acid (20-HETE) reduced Na/K-ATPase α1 expression via the ubiquitin-proteasome pathway. The ubiquitination level of Na/K-ATPase α1 protein was increased in 20-HETE-treated mouse cortical collecting duct cells and the kidney tissues of CYP4F2 transgenic mice. We also demonstrated that 20-HETE-induced high level phosphorylation of Na/K-ATPase α1 was necessary for its ubiquitination.

The present study aimed to test whether 20-hydroxyeicosatetraenoic acid (20‑HETE) affected neddylation modification of E3‑ligase Nedd4‑2 (neural precursor cell expressed, developmentally down‑regulated 4‑like, E3 ubiquitin protein ligase). A cytochrome P450 family 4 subfamily F member 2 (CYP4F2) transgenic mouse model that overproduces 20‑HETE in the kidney and the liver was used in the present study. Transgenic mice with high salt intake exhibited increased activation of Nedd4‑2‑mediated ubiquitin‑proteasome pathway.

We previously generated cytochrome P450 4F2 (CYP4F2) transgenic mice that have high levels of 20-hydroxyeicosatetraenoic acid (20-HETE) production; these mice exhibit both hypertension and hyperglycemia without insulin resistance. Currently, it is unclear whether and how 20-HETE affects insulin secretion, thus resulting in hyperglycemia. In this study, we found that 20-HETE attenuated glucose-stimulated insulin secretion (GSIS) in CYP4F2 transgenic mice as well as in rat insulinoma INS-1E cells treated with 0.
