To further elucidate how Linc00511 affects tumor growth in vivo, we subcutaneously injected A549 cells stably transfected with Ad-sh-NC, Ad-sh-linc00511 + Ad-NC or Ad-sh-linc00511 + Ad-COL1A1 into the right flank of nude mice to establish a xenograft model. This evidence concerns the gene LINC00511 and neoplasm.
