Functionally interdependent editing and methylation

Editing and methylation at a single site by functionally interdependent activities …cytosine 32 in the anticodon loop of Trypanosoma brucei tRNAThr is methylated to 3-methylcytosine (m3C) as a pre-requisite for C-to-U deamination. Formation of m3C in vitro requires the presence of both the T. brucei m3C methyltransferase TRM140 and the deaminase ADAT2/3. Once formed, m3C is deaminated to 3-methyluridine (m3U) by the same set of enzymes. ADAT2/3 is a highly mutagenic enzyme4, but we also show that when co-expressed with…

Dobzhansky 1973 and precision medicine

MicroRNA-34 directly targets pair-rule genes and cytoskeleton component in the honey bee Our findings point to miR-34-5p as novel regulatory component in the complex molecular cascade that governs insect segmentation and to a broader role of miRNAs in the early development due to the detection of mature transcripts from both 5p and 3p arms for several precursor miRNAs. Thus, this work encourages further investigation to pinpoint miRNAs as fine tuners of insect early development. Anna Di Cosmo‘s group took the…

Expunging the distinguished public

Royal Society Expunges Public From Evo Record Many of the attendee-participants were, in fact, more distinguished than many of the actual speakers. So the audience came to be heard as well as to listen. But the official recording (now posted) has been wiped clean of public comment — the most robust part of the meeting — and what we are left with, with few exceptions, is a series of academic lectures and old science. Thanks for continuing to make the…
