RNA synthesis, which is also called DNA transcription, is a highly selective process. Transcription by RNA polymerase II extends beyond RNA synthesis, towards a more active role in mRNA maturation, surveillance and export to the cytoplasm.

Single-strand breaks are repaired by DNA ligase using the complementary strand of the double helix as a template, with DNA ligase creating the final phosphodiester bond to fully repair the DNA.DNA ligases discriminate against substrates containing RNA strands or mismatched base pairs at positions near the ends of the nickedDNA. Bleomycin (BLM) exerts its genotoxicity by generating free radicals, whichattack C-4′ in the deoxyribose backbone of DNA, leading to opening of the ribose ring and strand breakage; it is an S-independentradiomimetic agent that causes double-strand breaks in DNA.

First strand cDNA is synthesized using random hexamer primers and M-MuLV Reverse Transcriptase (RNase H). Second strand cDNA synthesis is subsequently performed using DNA Polymerase I and RNase H. The remaining overhangs are converted into blunt ends using exonuclease/polymerase activity. After adenylation of the 3′ ends of DNA fragments, NEBNext Adaptor with hairpin loop structure is ligated to prepare the samples for hybridization. Cell cycle and DNA replication are the top two pathways regulated by BET bromodomain inhibition. Cycloheximide blocks the translation of mRNA to protein.

    L-Asparagine-1,2,3,4-13C4 monohydrate
    L-Asparagine-1,2,3,4-13C4 monohydrate is the 13C labeled labeled L-Asparagine monohydrate (HY-W017443). L-Asparagine monohydrate is an essential amino acid for leukemic cells and a substrate for L-Asparaginase. L-Asparaginase is a potent anti-leukemic enzyme that promotes asparagine (Asn) and glutamine (Gln) depletion and inhibits protein biosynthesis in lymphoblasts. Removal of L-asparagine from plasma by L-Asparaginase results in inhibition of RNA and DNA synthesis and subsequent apoptosis. L-Asparaginase has cell-killing ability in vitro and in vivo, and selectively inhibits the growth of cancer cells with low asparagine synthetase (AASNS) expression. L-Asparagine monohydrate can be used as a biomarker and sensor for the study of childhood acute lymphoblastic leukemia.
