MicroRNAs (miRNAs) are short, 22–25 nucleotide long transcripts that may suppress entire signaling pathways by interacting with the 3’-untranslated region (3’-UTR) of coding mRNA targets, interrupting translation and inducing degradation of these targets. The long 3’-UTRs of brain transcripts compared to other tissues predict important roles for brain miRNAs. Supporting this notion, we found th...

Sarcoma 37 cells grew more rapidly in castrated male mice than in controls of the same genotype; however, this effect of castration was dependent on the host genotype. Among inbred YS/Wf mice, tumor weight was increased only in castrated yellow Ay/a males and not in the comparable black a/a males. In contrast, mean tumor weight was increased in both yellow Avy/a and black a/a castrated males of...

Here we show that keratinocytes in psoriatic lesional skin express increased Toll-like receptor (TLR) 9 that similarly localizes with elevated expression of the cathelicidin antimicrobial peptide LL-37. In culture, normal human keratinocytes exposed to LL-37 increased TLR9 expression. Furthermore, when keratinocytes were exposed to LL-37 and subsequently treated with TLR9 ligands, such as CpG o...

Antimicrobial peptide IG-25 (a truncated version of LL-37 of the cathelicidin family) tethering an azido-capped poly(ethylene glycol) chain at the N-terminus was site-specifically attached to alkynyl-terminated polymerized liposomes using copper catalyzed "click" reaction, leading to an 18 fold enhancement in efficacy against Pseudomonas aeruginosa when compared to LL-37 without any increase in...
