Under normoxia, HIF-1 is hydroxylated by oxygendependent prolyl hydroxylase, and also the hydroxylated HIF-1 is subjected for proteasomal degradation. Hypoxia, therefore, stabilizes HIF-1 by limiting the hydroxylase activity [3, 4].SET2 The upregulated HIF-1 activity alters the expression of more than 60 downstream target genes, and numerous of those genes are associated with cancer progression involving metabolic adaption, apoptosis resistance, angiogenesis, and metastasis [5].PMID:23715856 The correlation in between the high intratumoral HIF-1 protein levels and also the enhanced mortality rates of cancer sufferers has been reported [6, 7]. Therefore, any mechanism to suppress the HIF-1 function could potentially be an effective method for new anticancer drug improvement. The protein transduction domains (PTDs) have been shown to correctly provide a wide variety of “cargos” like peptides, proteins, polyanionic oligonucleotides, and liposomes across the mammalian cell membrane in both size and concentration-independent manners [8]. For instance, the transactivator of transcription (TAT) PTD is usually a short arginine-rich 11 amino acid peptide (YGRKKRRQRRR), that is amino acid 477 in the human immunodeficiency virus TAT protein. TAT PTD strongly interacts with all the cell surface mainly because of its positive-charged arginine-rich sequence. After penetrating into cells through lipid raft-mediated endocytosis, the TAT fusion that survives through lysosomal degradation escapes from endosomes to cytoplasm to elicit function [9]. Previously we discovered Ainp1, which can be an ARNT-interacting peptide of 59 amino acids in length, working with a phage display system [10]. We o.
