APCDD1L-AS1 is transferred extracellularly via exosome incorporation in 5-FU-Resistant OSCC Cells

(A) APCDD1L-AS1 expression was detected by RT-qPCR after cells were treated with 1 μg/mL RNase A or 1 μg/mL RNase A + 0.1% Triton X100 for 30 min. (B) The exosomes images secreted by HSC-3/5-FU and HN-4/5-FU cells were showed by TEM scanning. (C) The levels of CD63 and CD9 proteins were measured by Western blot in HSC-3/5-FU and HN-4/5-FU cells. (D) APCDD1L-AS1 expression in exosomes of parental and 5-FU-sensitive NSCLC cells was detected by RT-qPCR. **P < 0.01.
