Epigenetic changes frequently occur in human colorectal cancer. Genomic global hypomethylation, gene promoter region hypermethylation, histone modifications, and alteration of miRNA patterns are major epigenetic changes in colorectal cancer. Loss of imprinting(LOI) is associated with colorectal neoplasia. Folate deficiency may cause colorectal carcinogenesis by inducing gene-specific hypermethy...

In the present study, we aimed to examine whether SET domain-containing methyltransferases are up-regulated in different classes of renal cell carcinoma. We immunoblotted against SET domain and quantified the expression of these modular domains. Furthermore, we examined the expression of Rad51, the key protein that confers genomic stability. There was enhanced expression of SET domain-containin...

Pseudomonas aeruginosa is a biofilm-forming opportunistic pathogen which causes chronic infections in immunocompromised patients and leads to high mortality rate. It identified as common coinfecting COVID-19 causing exacerbation of illness. In our hospital, P. one the top bacteria among patients. We collected strong strain displaying small colony variant morphology from severe patient. Genomic ...

Gene regulatory regions in noncoding genomic sequences are subject to stabilizing selection and therefore evolve much slower than adjacent non-functional DNA. The resulting phylogenetic footprints can be detected by comparison of the sequences surrounding orthologous genes in different species [8]. Experimental evidence from a variety of sources shows that a major mode of developmental gene evo...

Efficient fermentation of hemicellulosic sugars is critical for the bioconversion of lignocellulosics to ethanol. Efficient sugar uptake through the heterologous expression of yeast and fungal xylose/glucose transporters can improve fermentation if other metabolic steps are not rate limiting. Rectification of cofactor imbalances through heterologous expression of fungal xylose isomerase or modi...

In the presence of tetramethylammonium chloride, potassium permanganate specifically modifies mismatched thymines. Similarly, the modification of mismatched cytosines by hydroxylamine was enhanced by tetraethylammonium chloride. Modification followed by piperidine cleavage permits specific identification of the T and C mismatches and by extension, when the opposite DNA strand is analyzed, of A ...

Sexual size dimorphism (SSD), a difference in body size between sexes, is common in many taxa. In insects, females are larger than males in >70% of all taxa in most orders. The fruit fly, Drosophila melanogaster is one prominent model organism to investigate SSD since its clear and representative female-biased SSD and its growth regulation are well studied. Elucidating the number and nature of ...

UNLABELLED The human pathogen Streptococcus pneumoniae (pneumococcus) exhibits a high degree of genomic diversity and plasticity. Isolates with high genomic similarity are grouped into lineages that undergo homologous recombination at variable rates. PMEN1 is a pandemic, multidrug-resistant lineage. Heterologous gene exchange between PMEN1 and non-PMEN1 isolates is directional, with extensive g...

Stenotrophomonas maltophilia bacteriophage DLP5 is a temperate phage with Siphoviridae family morphotype. DLP5 (vB_SmaS_DLP_5) is the first S. maltophilia phage shown to exist as a phagemid. The DLP5 genome is 96,542 bp, encoding 149 open reading frames (ORFs), including four tRNAs. Genomic characterization reveals moron genes potentially involved in host cell membrane modification.
