Periodicities in introns

open access: yesNucleic Acids Research, 1987
The sequence information for the splicing process of introns is found in the consensus sequences at the two splice sites. For long introns, of 300 or more nucleotides, the middle regions may provide additional specificity for splicing which can be investigated by defining an adequate quantitative parameter.

Evidence of widespread degradation of gene control regions in hominid genomes [PDF]

open access: yes, 2005
Although sequences containing regulatory elements located close to protein-coding genes are often only weakly conserved during evolution, comparisons of rodent genomes have implied that these sequences are subject to some selective constraints ...

Substitution of the α-lactalbumin transcription unit by a CAT cDNA within a BAC clone silenced the locus in transgenic mice without affecting the physically linked Cyclin T1 gene

open access: yesGenetics Selection Evolution, 2003
We recently reported that a goat bacterial artificial chromosome (BAC) clone conferred site-independent expression in transgenic mice of the two loci present within its insert, the ubiquitously expressed Cyclin T1 and the mammary specific β-lactalbumin ...

Improved osteogenic vector for non-viral gene therapy [PDF]

open access: yesEuropean Cells & Materials, 2016
Therapeutic compensation of deficient bone regeneration is a challenging task and a topic of on-going search for novel treatment strategies. One promising approach for improvement involves non-viral gene delivery using the bone morphogenetic protein-2 ...

DNA-based S-genotyping of Japanese plum and pluot cultivars to clarify incompatibility relationships [PDF]

open access: yes, 2007
Diploid japanese plum (Prunus salicina Lindl.) cultivars are commonly self-incompatible. To date, 14 incompatibility alleles (S-alleles) have been identified and labeled with alphabetical (S-a-S-n) and 5 with numeric codes (S-1, S-3-S-6).

Novel Genomic and Evolutionary Perspective of Cyanobacterial tRNAs

open access: yesFrontiers in Genetics, 2017
Transfer RNA (tRNA) plays a central role in protein synthesis and acts as an adaptor molecule between an mRNA and an amino acid. A tRNA has an L-shaped clover leaf-like structure and contains an acceptor arm, D-arm, D-loop, anti-codon arm, anti-codon ...

Characterization of a disease-associated mutation affecting a putative splicing regulatory element in intron 6b of the cystic fibrosis transmembrane conductance regulator (CFTR) gene [PDF]

open access: yes, 2009
Cystic fibrosis (CF) is a common recessive disorder caused by >1600 mutations in the CF transmembrane conductance regulator (CFTR) gene. About 13% of CFTR mutations are classified as “splicing mutations,” but for almost 40% of these, their role in ...

Expression of the C-allele of intronic rs8192675 in SLC2A2 is associated with improved glucose response to metformin [PDF]

open access: yesGenetics and Molecular Biology
Glucose is a critical nutrient for energy metabolism. The SLC2A2 gene is essential for glucose sensing and homeostasis, as it encodes the facilitated glucose transporter GLUT2. During diabetes treatment, the C-allele of rs8192675 in SLC2A2 has been found

Global Characterization of Fungal Mitogenomes: New Insights on Genomic Diversity and Dynamism of Coding Genes and Accessory Elements

open access: yesFrontiers in Microbiology, 2021
Fungi comprise a great diversity of species with distinct ecological functions and lifestyles. Similar to other eukaryotes, fungi rely on interactions with prokaryotes and one of the most important symbiotic events was the acquisition of mitochondria ...
