MALAT1 was secreted by packaging into exosomes. (A) The expression of MALAT1 in A549 and H1299 cell medium treated with RNase A or RNase A+Triton X 100 was measured using qRT-PCR. (B) The representative characteristic of exosomes was observed using TEM. (C) The size distribution of exosomes was analyzed by NTA using Zetasizer. (D) Exosome marker proteins (CD63 and CD81) were quantified by Western blot. *P < 0.05.
