Tomohide Takaya, research group leader, concluded: “We believe there is a strong case to be made for further studies evaluating DNA aptamers in regenerative medicine. Aptamers are cost-effective and open up the possibility of producing specific cells from the patient’s stem cells. But it doesn...
Biased mating due to female preferences towards certain traits in males is a major mechanism driving sexual selection, and may constitute an important evolutionary force in organisms with sexual reproduction. In birds, although the role of male ornamenta
Analysis of the DNA and RNA changes associated with the expression of isotypic variant-specific antigens of trypanosomes. Using specific (32P) labelled cDNA probes, we compared the mRNAs and the genomic DNA sequences coding for the synthesis of two pairs of serologically relat... E Pays,M L...
Carbohydrates act as coenzymes for the production of cellular energy, as well as it serves as a structural component of nucleic acid molecules such as DNA (Deoxyribose) and RNA (Ribose). The derivatives of saccharides, as well as themselves, have regulatory functions in the immune system as ...
IGF-1R inhibition enhances radiosensitivity and delays double-strand break repair by both non-homologous end-joining and homologous recombination (DNA-PK)-proficient but not DNA-PK-deficient glioblastoma cells, and did not radiosensitize DNA-PK-inhibited DU145 cells, suggesting that in the context.....
Within the human population, there are a num- ber of MHC haplotypes called conserved extended haplotypes (CEHs), which exhibit distinctively long stretches of nearly identical sequences where recombination events appear to be unusually low or absent over megabases of DNA7,8. It has been ...
Once ERα is expressed and activated by estradiol, it binds to ERE-DNA elements and activates the transcription of GFP (Figs. 1A and S1B). Using the ERE-GFP reporter in SUM149PT cells, we conducted a high-throughput drug screen with 9 501 compounds (Supplementary Table 1). Fig. 1: ...
The four nucleotides that comprise DNA are adenine (A), thymine (T), guanine (G), and cytosine (C). These nucleotides always form Watson and Crick pairs in the same configuration, A-T and C-G and when a number of these pairs come together they form the doubl...
