As expected, the high level of lyso-PS (18:0) was detected in ectopic miR-4646-5p or ABHD16A expressing gastric cancer cells (GC/Drosha WT/miR4646-5p, and GC/Drosha WT/ABHD16A), loss of miR-4646-5p or ABHD16A in Drosha-silenced GC cells (GC/Drosha KD/sh-miR4646-5p, and GC/Drosha KD/sh-ABHD16A) led to decrease of lyso-PS (18:0) (Fig. 5G). This evidence concerns the gene DROSHA and gastric cancer.
