In 2020 we published Liftoff, which was the first standalone tool specifically designed for transferring gene annotations between genome assemblies of same or closely related species. While content is expected to be very similar in genomes, differences may biologically consequential, and a computational method extract all gene-related should prove useful analysis such genomes. Here present Lift...

Background: Gastric cancer (GC) is considered as one of the most common types of cancer worldwide with poor prognosis and generally limited treatment options. Recent studies have indicated that HER2, MDM2, MYC, MET, and TP53 play an important role in the development of gastric cancer. Therefore, the aim of this study was to evaluate the incidence of amplification/deletion of these genes in pati...

Differential PCR was performed to determine the copy number of rRNA genes in Pneumocystis carinii f. sp. hominis. Two different reference genes, thymidylate synthase (TS) and beta-tubulin (BTU) genes, were used. Primers for the internal transcribed spacer (ITS) region of nuclear rRNA genes and either the TS or BTU gene were mixed together to perform PCR on seven different bronchoalveolar lavage...

Metabolic enzymes rarely regulate informational processes like gene expression. Yeast acetyl-CoA synthetases (Acs1p and 2p) are exceptional, as they are important not only for carbon metabolism but also are shown here to supply the acetyl-CoA for histone acetylation by histone acetyltransferases (HATs). acs2-Ts mutants exhibit global histone deacetylation, transcriptional defects, and synthetic...

a significant portion of the world’s cultivated land is affected by salinity that reduces crop productivity in these areas. breeding for salt tolerance is one of the important strategies to overcome this problem. recently, genetic engineering is becoming a promising approach to improving salt tolerance. in order to improve the yield performance of canola in saline soils, we transformed canola w...

in previous years, identification of fetal cells in maternal blood circulation has caused a new revolution in non-invasive method of prenatal diagnosis. low number of fetal cells in maternal blood and long-term survival after pregnancy limited the use of fetal cells in diagnostic and clinical applications. with the discovery of cell-free fetal dna (cffdna) in plasma of pregnant women, access to...

Gene duplication played a fundamental role in eukaryote evolution and different copies of given gene can be present extant species, often with expressions functions differentiated during evolution. We assume that, when such differentiation occurs copy, this may indicated by its maintenance all the derived species. To verify hypothesis, we compared histological expression domains three β-glucuro...

To investigate the relationships between Chromosome 7 gain, mesenchymal-epithelial transition factor (MET) gene copy number increase and MET protein overexpression in Chinese patients with papillary renal cell carcinoma (PRCC), immunohistochemistry (IHC), immunofluorescence (IF) and fluorescence in situ hybridization (FISH) were performed on 98 formalin-fixed, paraffin-embedded (FFPE) PRCC samp...

Nuclear factor (erythroid-derived 2)-like 2 (NRF2) is a transcription factor belonging to the cap 'n' collar subfamily of the basic-leucine zipper (bZIP) family of transcription factors, which plays a significant role in adaptive responses to oxidative stress. Previously, we reported that NRF2 gene (NFE2L2) mutations correlate with poor prognosis of lung squamous cell carcinomas. We therefore h...
