Research ArticleOpen accessEvery word in the titleMinimum Free Energy Based Evaluation of mRNAs Secondary Structures Constructed by 18 Clinically Significant Exonic Single Nucleotide Polymorphisms (SNPs) and Haplotypes of 5 Missense SNPs of RB1 GeneSarder Nasir Uddin, Apurba Majumder, Khandker Khaldun Islam et al.Clinically significant 18 Single Nucleotide Polymorphisms (SNPs) from exon regions of Retinoblastoma gene (RB1) were analyzed to find out the structural variations in mRNAs. Online bioinformatic tools i.e., Vienna RNA, RNAfold were used for secondary structure analysis of mRNAs. Predicted minimum Free Energy Change (MFE) was calculated for mRNAs structures. It has been observed that the average of predicted MFE … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 4 · 21 Oct 2015 · 8,556 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleG-2548A Leptin Promoter and Q223R Leptin Receptor Polymorphisms in Obese Mexican SubjectsP. Carrillo-Vazquez Jonathan, Lopez-Alcantar Jeronimo, Chimal-Vega Brenda et al.Leptin interaction with its receptor in the hypothalamus stimulates a specific signaling cascade that results in the synthesis of anorexigenic and orexigenic peptides in order to regulate food intake and energy expenditure. Many polymorphisms in leptin (lep) and leptin receptor (lepr) genes have been associated with body weight. In particular, G-2548A in the lep promoter and Q223R in lepr variants … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 1 · 12 Feb 2013 · 8,641 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleCharacterization of Bovine Calpastatin Gene in Nelore Cattle Using Polymerase Chain Reaction-Restricted Fragment Length PolymorphismsAlireza Majidi, Jothi Malar Panandam, Awis Qurni Sazili, Siti Shapor SirajProblem statement: In beef cattle production, of meat quality and carcass traits are important. Traditionally beef cattle breeding programs unfortunately are time consuming and also recording of carcass and growth traits need heavy cost, Approach: Marker Assisted Selection (MAS) should be utilized in beef herds, along with economically important phenotypic traits, for genetic progress to made with respect to improving … …American Journal of Animal and Veterinary Sciences, Vol. 4, Issue 4 · 31 Dec 2009 · 7,329 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleGenome-Wide Association Study of Single Nucleotide Polymorphisms with Milk Traits in Red Gorbatov CattleMarina Ivanovna Selionova, Grigorii Sergeyevich Shekhovtsev, Ivan Petrovich Prokhorov et al.In order to preserve the gene pool of the Red Gorbatov breed, it is necessary to use a set of genomic analysis tools that allows more efficient planning in obtaining individuals who meet the economic requirements of dairy farming. The aim of the work was to identify candidate genes associated with milk production traits in Red Gorbatov cattle using a … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 4 · 12 Oct 2024 · 4,736 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleDistribution of Alleles and Genotypes of ACE2 Gene Polymorphisms (rs2285666 and rs35803318) and Association with COVID-19 Among Populations in KazakhstanAnar Bisseneva, Konstantin Li, Gayane Pogossyan, Valeriya ProtasThere is still no definitive confirmation regarding the association between ACE2 gene polymorphisms and COVID-19. This study was conducted to analyze the distribution of alleles and genotypes of the ACE2 gene rs2285666 and rs35803318 two polymorphisms and their possible association with COVID-19 among two ethnic groups, namely, the Kazakhs and Eastern Slavs, residing within the same geographic area in the … …OnLine Journal of Biological Sciences, Vol. 24, Issue 1 · 31 Oct 2023 · 4,942 accessesView PDFCite
