Genomic rearrangements, such as intragenic deletions and duplications, are the most prevalent types of mutation in the DMD gene, and DMD mutations underlie Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD). Using multiplex ligation dependent probe amplification (MLPA) and DMD gene-targeted sequencing, we performed a molecular characterization of two cases of complex noncontiguous...
Acute lung injury/acute respiratory distress syndrome (ALI/ARDS) is a common critical emergency with high mortality in clinical practice. The key mechanism of ALI/ARDS is that the excessive inflammatory response damages the integrity of alveolar and bronchial cell membrane and thus affects their basic function. Phospholipids are the main component of cell membranes. Phospholipase A2 (PLA2), which...
Similar to the regular enzymatic glycosylation, glycation also attaches a sugar molecule to a peptide, but does not need the help of an enzyme. Glycation may occur both inside and outside the host body, and will compete with the glycosylation procedure for functional regulation of mature protein products. The glycated residues do not show significant patterns, which make both in silico sequence-level...
Antibiotic resistance is a serious problem in health care and is of widespread public concern. Conjugative plasmids are the most important vectors in the dissemination of antibiotic resistance genes. In this study, we determined the complete sequence of plasmid pNA6, a plasmid which was isolated from the sediments of Haihe River. This plasmid confers reduced susceptibility to ampicillin, erythromycin...
In the current study, cell lines including HEK293, SW480, HPASMC, HPCASMC and HAEC were cultured with 5-aza-2-deoxycytidine (DAC) and 17-β-estradiol to investigate whether PLA2G7 transcription was under the control of promoter methylation and 17-β-estradiol. Luciferase reporter gene assays were used to evaluate whether reporter gene activity was enhanced by PLA2G7 promoter fragment. Gene expression...
Colon cancer is one of the major causes of cancer-related death in the world. Understanding the molecular mechanism underlying this malignancy will facilitate the diagnosis and treatment. Serine-arginine protein kinase 2 (SRPK2) has been reported to be upregulated in several cancer types. However, its expression and functions in colon cancer remains unknown. In this study, it was found that the expression...
Sumoylation is a multifunctional post-translation modification (PTM) in proteins by the small ubiquitin-related modifiers (SUMOs), which have relations to ubiquitin in molecular structure. Sumoylation has been found to be involved in some cellular processes. It is very significant to identify the exact sumoylation sites in proteins for not only basic researches but also drug developments. Comparing...
The miR2118 is highly conserved in leguminous plants. Its function is to regulate the expression of genes encoding the TIR-NBS-LRR resistance protein. In this study, cin-miR2118 from Caragana intermedia was functionally characterized, especially with regard to its role in drought stress resistance. Two target genes of cin-miR2118 were predicted and cloned, the occurrence of miR2118 target sequence...
Plant aquaporins are responsible for water transmembrane transport, which play an important role on abiotic and biotic stresses. A novel plasma membrane intrinsic protein of CaPIP1-1 was isolated from the pepper P70 according to transcriptome databases of Phytophthora capsici inoculation and chilling stress library. CaPIP1-1, which is 1155bp in length with an open reading frame of 861bp, encoded 286...
Autosomal recessive polycystic kidney disease (ARPKD) is a rare hereditary renal cystic disease involving multiple organs, mainly the kidney and liver. Parents who had an affected child with ARPKD are in strong demand for an early and reliable prenatal diagnosis to guide the future pregnancies. Here we provide an example of prenatal diagnosis of an ARPKD family where traditional antenatal ultrasound...
Opitz G/BBB syndrome (OS) is a genetically heterogeneous disease. We report on an OS patient with a novel inherited mutation in MID1. Metaphase analysis showed a normal male karyotype. Array CGH revealed a maternally inherited duplication at Xp22.31 (6,467,203–7,992,261, hg18), the size was estimated to 1.5Mb. Sequence analysis of the MID1 coding region revealed a novel missense mutation in exon 8...
Phenotypic similarity is correlated with a number of measures of gene function, such as relatedness at the level of direct protein–protein interaction. The phenotypic effect of a deleted or mutated gene, which is one part of gene annotation, has caught broad attention. However, there have been few measures to study phenotypic similarity with the data from Human Phenotype Ontology (HPO) database, therefore...
Our previous studies have shown that SHP-1, a SH2 domain-containing protein-tyrosine phosphatase, is expressed not only in cells of hematopoietic lineages, but also in many non-hematopoietic cells under the control of an alternative tissue-specific promoter, P1. In this study, the activity of the P1 promoter was analyzed in a region spanning 3.5 kb upstream of the major transcription start site in...
