Tyrosinase is a copper-containing enzyme that regulates melanin biosynthesis and is encoded by the tyrosinase (TYR) gene. Previous studies demonstrated that mutations in TYR could lead to oculocutaneous albinism type 1 (OCA1) owing to the failure of melanin formation. Although a previous study found that albinism in the rhesus monkey was derived from a mutation in TYR, the identification and characterization...
Mitochondria are subcellular organelles that contribute to aerobic ATP generation by oxidative phosphorylation (OXPHOS). Previous studies reported that mitochondrial dysfunction and deficiency caused by mitochondrial DNA polymorphisms is associated with various diseases. Especially, mitochondrial DNA 10398 A/G polymorphism is known to affect the regulation of mitochondrial calcium levels related to...
The proliferation and differentiation of skeletal muscle satellite cells is regulated by multiple regulatory factors including non-coding RNAs. It has been reported that miR-133b regulates myogenesis. In this study, we detected a novel lncRNA, lnc133b, which is completely complemented by mature miR-133b, indicating that lnc133b may regulate the expression of miR-133b by “sponge” miR-133b. A luciferase...
Long non-coding RNA (lncRNA) MEG3 (maternally expressed gene 3) is an imprinted gene that suppresses cells growth in various tumors. However, the association between MEG3 expression and prognosis in non-small cell lung cancer (NSCLC) has not been fully investigated. Seven datasets with 1144 patients were obtained from Gene Expression Omnibus (GEO) database (Affymetrix U133 Plus 2.0 platform). Association...
Although purified and synthesized Cecropin A-magainin 2 (CAMA-syn) shows potent antibacterial activity in vitro, its ability to inhibit bacteria within mammal cells mediated by virus vector has not yet been investigated. To enhance its antimicrobial potential and reduce systemic side effects, it would be desirable to deliver CAMA-syn in macrophages by adenovirus vector. In this study,recombinant adenovirus...
Codon usage bias (CUB) is extensively found in a wide variety genomes and it is mostly affected by mutation pressure and natural selection. Analysis of CUB helps in studying the evolutionary features of a genome. The SRY gene plays an important role in male reproductive organ and a good candidate to study the evolutionary forces, since little work was reported earlier on this gene. We used bioinformatic...
The scavenger receptor type B class I (SCARBI) is known to be involved in the entry of hepatitis C virus (HCV) into the host, while interleukin-15 (IL15) is an important cytokine in both the innate and acquired immune responses against HCV infection. We investigated the association of IL15 rs10833 or SCARB1 rs10846744 polymorphisms with treatment responses in patients with chronic HCV (CHC). SCARB1...
Colorectal cancer (CRC) is increasingly common worldwide, including in China. Therefore, there is an increasing need to detect CRC at an early stage and to discover and evaluate diagnostic and prognostic biomarkers. DNA methylation of genes in CRC is a potential epigenetic biomarker for the early detection of CRC. This study was performed to analyze the methylation frequency of six candidate genes,...
Mesenchymal stem cells (MSCs) are well recognized for their ability to differentiate into type II alveolar epithelial (ATII) cells in damaged lungs, which is critical for reepithelization and recovery in acute lung injury (ALI). However, the high level of transforming growth factor-β (TGF-β) commonly seen in injured lung tissues is also able to induce MSCs to differentiate into fibroblast-like cells...
Aniridia is a rare, congenital ocular disorder caused by the mutations of the paired box gene-6 (PAX6) (OMIM 607108), which encodes a highly conserved transcriptional regulator. In order to investigate the clinical characterizations and genetic defects of two Chinese families affected with aniridia, we recruited the family members and 200 ethnically matched controls. The entire exons and flanking...
