... BACKGROUND: The fur color constitutes one of the most important economic characteristics of fur animals and is determined by the content of melanin. A previous study has shown that the cyclin-dependent kinase 1 (CDK1) is a member of the protein kinase family, involved in forming the color of the fur in Rex rabbits. However, its effect on the melanocytes remains unclear. OBJECTIVE: This study aimed ...

OBJECTIVE: To successfully protect and restore the highly endangered freshwater fish G. naktongensis from the Geum River in South Korea. METHODS: The mitogenome was characterized using the primer walking method with phyl ...
... BACKGROUND: Coffin-Siris syndrome (CSS) is a rare congenital syndrome characterized by developmental delay, intellectual disability, microcephaly, coarse face and hypoplastic nail of the fifth digits. Heterozygous variants of different BAF complex-related genes were reported to cause CSS, including ARID1A and SMARCA4. So far, no CSS patients with ARID1A and SMARCA4 variants have been reported in C ...
... BACKGROUND: The genus Microbacterium belongs to the family Microbacteriaceae and phylum Actinobacteria. A detailed study on the complete genome and systematic comparative analysis of carbohydrate-active enzyme (CAZyme) among the Microbacterium species would add knowledge on metabolic and environmental adaptation. Here we present the comparative genomic analysis of CAZyme using the complete genome ...
... BACKGROUND: Mitochondrial complex I deficiency (MCID) is the most common biochemical defect identified in childhood with mitochondrial diseases, mainly including Leigh syndrome, encephalopathy, macrocephaly with progressive leukodystrophy, hypertrophic cardiomyopathy and myopathy. OBJECTIVE: To identify genetic cause in a patient with early onset autosomal recessive MCID. METHODS: Trio whole-exome ...

Abstract:
... BACKGROUND: A review of research shows that methylation in plants is more complex and sophisticated than in microorganisms and animals. Overall, studies on the effects of abiotic stress on epigenetic modifications in plants are still scarce and limited to few species. Epigenetic regulation of plant responses to environmental stresses has not been elucidated. This study summarizes key effects of ab ...
... BACKGROUND: Pseudomonas aeruginosa is an important opportunistic pathogen especially in nosocomial infections due to its easy adaptation to different environments; this characteristic is due to the great genetic diversity that presents its genome. In addition, it is considered a pathogen of critical priority due to the high antimicrobial resistance. OBJECTIVES: The aim of this study was to charact ...

Abstract:
... BACKGROUND: Among various human endogenous retroviruses (HERVs), the HERV-K (HML-2) group has been reported to be highly related to cancer. In pancreatic cancer cells, shRNA-mediated downregulation of HERV-K env RNA decreases cell proliferation and tumor growth through the RAS-ERK-RSK pathway; in colorectal cancer, CRISPR-Cas9 knockout (KO) of the HERV-K env gene affects tumorigenic characteristic ...
... BACKGROUND: Hypoxia can induce lung injury such as pulmonary arterial hypertension and pulmonary edema. And in the rat model of hypoxia-induced lung injury, the expression of Farnesyl diphosphate farnesyl transferase 1 (Fdft 1) was highly expressed and the steroid biosynthesis pathway was activated. However, the role of Fdft 1 and steroid biosynthesis pathway in hypoxia-induced lung injury remains ...
... BACKGROUND: Oxidative stress is one of the most important factors affecting large-scale breeding, especially the performance of pigs. Oxidative stress plays a role by affecting various genes in pigs, which can cause serious body damage, functional degradation and reduce production performance. OBJECTIVE: The purpose of this study was to investigate the effect of Toll like receptor 9 (TLR9) pathway ...
... BACKGROUND: Although plants may be regularly exposed to various abiotic stresses, including drought, salt, cold, heat, heavy metals, and UV-B throughout their lives, it is not possible to actively escape from such stresses due to the immobile nature of plants. To overcome adverse environmental stresses, plants have developed adaptive systems that allow appropriate responses to diverse environmenta ...
... BACKGROUND: Dynamic chromatin reorganization occurs during two waves of cell lineage specification process, blastocyst formation and gastrulation, to generate distinct cell types. Epigenetic defects have been associated with severe developmental defects and diseases. How epigenetic remodeling coordinates the two lineage specification waves is becoming uncovered, benefiting from the development and ...

Abstract:
... BACKGROUND: Mitogen-activated protein kinases (MPKs) play important role in response to environmental stress as crucial signal receptors or sensors. Our previous study indicated that salt stress acts as a positive factor to stimulate the production of pharmacodynamic metabolites in the medicinal plant Glycyrrhiza uralensis. Currently, little is known about the MPK gene family and their functions i ...
... BACKGROUND: Neuropathic pain is a common condition with current heights of varying etiology. The therapeutic drugs are also poorly work and often limited by side effects such as dizziness. OBJECTIVE: This study aimed to explore the function mechanism of GADD45A in neuropathic pain. METHODS: The DEGs in neuropathic pain mouse model chip were screened by bioinformatics analysis.

... For much of the twentieth century, it was accepted that genes dictate phenotypes. Nevertheless, genetics in combination with molecular biology and genomics has facilitated the explanation of some peculiar molecular phenomena. Most eukaryotic genomes are crammed with noncoding DNA, which was previously hypothesized to be selfish DNA, with only a small fraction of sequences encoding proteins. We now ...
