Tier IV GS411167 • Differentially expressed ncRNA in mouse striatum associated with addiction to oxycodone vs saline_qvalue

DESCRIPTION:

RNA‐seq was used to investigate the pathology of oxycodone abuse. In order to uncover the potential epitranscriptomic role of m6A methylation in oxycodone abuse, three different doses of saline or oxycodone (1.5, 3.0, and 6.0mg/kg) were administered intraperitoneally (i.p., 0.1mL/10g) to a group of mice for 9 days. Subsequently, after 4 days of oxycodone withdrawal and 1hr after open field testing, striatum samples from the experimental mice were collected for RNA‐sequencing (RNA‐seq) to detect m6A methylation‐associated enzymes and then examine m6A‐related epigenetic alterations. Total RNA was extracted from the striatum (n=3 C57BL/6J mice in each group), and the quantification of lncRNA, ncRNA, and mRNA followed. Quality‐checked libraries were sequenced on the DNBseq platform using MGISEQ‐2000 with 100PE sequencing. Library construction, lncRNA‐seq, ncRNA‐seq, and RNA‐seq, as well as data collection and mapping were outsourced to HuaDa Gene Biotechnology (Shenzhen, China). From supplementary table 1. Please note that the upregulated genes reported in the Results section correspond to negative fold change values in the table, and downregulated correspond to positive fold change values - this may or may not be an error in reporting by the authors.

TITLE:

METTL14-mediated upregulation of lncRNA HOTAIR represses PP1α expression by promoting H3K4me1 demethylation in oxycodone-treated mice.

ABSTRACT:

N6-methyladenosine (m6A) methylation is a vital epigenetic mechanism associated with drug addiction. However, the relationship between m6A modification and oxycodone rewarding is less well explored. Based on an open field test, the present study evaluated oxycodone rewarding using chromatin immunoprecipitation PCR, immunofluorescence, and RNA sequencing. A marked increase in METTL14 protein and a decrease in PP1α protein due to oxycodone abundance in the striatal neurons were observed in a dose- and time-dependent manner. Oxycodone markedly increased LSD1 expression, and decreased H3K4me1 expression in the striatum. In the open field test, intra-striatal injection of METTL14 siRNA, HOTAIR siRNA, or LSD1 shRNA blocked oxycodone-induced increase in locomotor activity. The downregulation of PP1α was also inhibited after treatment with METTL14/HOTAIR siRNA and LSD1 shRNA. Enhanced binding of LSD1 with CoRest and of CoRest with the PP1α gene induced by oxycodone was also reversed by LSD1 shRNA. In addition, H3K4me1 demethylation was also blocked by the treatment. In summary, the investigation confirmed that METTL14-mediated upregulation of HOTAIR resulted in the repression of PP1α, which in turn facilitated the recruitment of LSD1, thus catalyzing H3K4me1 demethylation and promoting oxycodone addiction.
