We also investigated the effects of SNRPD2 knockdown on a panel of cancer cell lines derived from different tumor tissues and on primary short-term cultured melanoma cells and non-malignant cells (vascular endothelial cells, pancreatic stellate cells, lymph node stromal cells, and lung fibroblasts, including cancer-associated fibroblasts from lung cancer resections). This evidence concerns the gene SNRPD2 and lung cancer.
