In mammalian cells, DNA methylation on the 5th position of cytosine (5mC) plays an important role as an epigenetic mark. However, DNA methylation was considered to be absent in C. elegans because of the lack of detectable 5mC as well as homologs of the cytosine DNA methyltransferases. Here, using mu...

N6-methyladenosine (m6A) is the most abundant ribonucleotide modification among the eukaryotic messenger RNAs (mRNAs). The m6A “writer” is composed of an m6A-METTL complex (MAC), the catalytic subunit, and an m6A-METTL associated complex (MACOM), the regulatory subunit essential for the enzymatic ac...

Optical density (OD) is widely used to estimate the density of cells in liquid culture, but cannot be compared between instruments without a standardized calibration protocol and is challenging to relate to actual cell count. We address this with an interlaboratory study comparing three simple, low-...
