Aligning very short sequences using bowtie2, I need fine control over how many mismatches are allowed. Adjust scoring?

Hi, I’m using bowtie2 to align very short sRNA sequences (18-45nt) to reference files. I’ve been using the very-sensitive-local preset to align to the human genome, and bowtie2 was allowing for one, maybe 2 mismatches. However when testing against shorter references (my tRNAs) the sequences with mismatches and gaps don’t…

Amphioxus adenosine-to-inosine tRNA-editing enzyme that can perform C-to-U and A-to-I deamination of DNA

Animals and cells Adult amphioxus B. japonicum collected from the sandy bottom of the sea near Qingdao, China, were cultured in aerated seawater at room temperature and fed with single-celled algae once a day. Zebrafish (D. rerio) aged 3 months and adult Japanese scallops (M. yessoensis) were purchased from Nanshan…

Characterizing expression changes in noncoding RNAs during aging and heterochronic parabiosis across mouse tissues

Mapping of ncRNA expression across mouse organs We sequenced 771 tissue samples of the TMS cohort to map molecular shifts across the whole organism during healthy aging (Fig. 1a). The protocol enriches for small ncRNA, especially mature miRNAs. Even though full-length reads cover only small ncRNAs (miRNAs or piwi-interacting RNAs…

Naming system for transfer RNA fragments will increase research productivity, standardization

Transfer RNA, more commonly referred to as tRNA, is well known for its key role in translating genetic material into protein. Recent discoveries about fragments of tRNA, which scientists had previously thought of as simply waste products in the cell ecosystem, has led to an increase in attention to these…

Profiling and functional characterization of maternal mRNA translation during mouse maternal-to-zygotic transition

INTRODUCTION Mammalian life starts with the fusion of two terminally differentiated gametes, sperm and oocyte, resulting in a totipotent zygote. After going through preimplantation development, the zygote reaches blastocyst before implantation. The two most important events taking place during preimplantation development are zygotic genome activation (ZGA) and the first cell…
