RNA maps reveal new RNA classes and a possible function for pervasive transcription. Furthermore, although referencing to either negative control A or B showed comparable lncRNA candidate knockdown levels, we described via in silico and in vitro analyses that the lipofectamine-based delivery of negative control B significantly inhibited LEC proliferation by deregulating several proliferation-related genes.

LETR1 is a lymphatic endothelial-specific lncRNA governing cell proliferation and migration through KLF4 and SEMA3C. The next day, LECs were transfected with 20nM of negative control ASO A or B and 16L Lipofectamine RNAiMAX previously mixed in 1.6mL Opti-MEM according to the manufacturers instructions and incubated for 24h. Transfected LECs were then detached and seeded at a 3000 cells/well density into a collagen-coated 96-well plate (plack plate, Costar). Future studies should also consider alternative delivery methods of the ASOs. KD efficiency for each ASO was checked by qPCR.
