Role of MAPK in H3K9 hypermethylation and autophagy inhibition. Expression of G9a transcripts was checked in RAW264.7 cells infected with MsmpSMT3and MtbPrtfollowed by treatment with (A) SB203580 and (B) U0126 for 24 h. Expression of (C) p-P38, (D) ATG5 and ATG7, (E) LC3-I to II conversion (Densitometry is representative to the particular western blot data), (F) H3K9me2/3, (G) H3K9ac and HDAC3 were checked in RAW cells infected with MsmpSMT3and MtbPrt in presence and absence of SB203580 (P38 inhibitor) for 24 h. The experiments were performed in triplicate (n=3). MsmpSMT3- Msm harbouring pSMT3 plasmid; MtbPrt- recombinant Msm expressing MtbPrt (Rv3242c). Results are shown as mean ± S.D. ***p < 0.001; ns, not significant.
