Sphingolipids are key components of the plasma membrane and are regulators of complex biological processes often altered in cancer cells. In human tumors, genes of key enzymes that regulate levels of glucosylceramide and lactosylceramide are often amplified. However, it is unknown why these traits are positively selected in transformed cells. In this work, we used CRISPR-Cas9 to knockout two key enzymes amplified in tumors in HeLa and H1703 tumor-derived cell-lines. As expected, the knockout lines had dramatic accumulation of GlcCer and LacCer. However, unexpectedly, they showed significantly decreased in-vitro wound-healing capacity and an almost complete loss of in-vitro extra-cellular matrix …

Malignant melanoma (MM) is the most aggressive skin cancer and the most frequent skin disorder in Caucasians. MM is associated with aggressive and progressive disease states, leading to major cancer-related morbidity and mortality. Recent investigations identify a new non-angiogenesis-dependent pathway vasculogenic mimicry (VM), which is considered a cancer hallmark that can independently facilitate tumor neovascularization by the formation of fluid-conducting and vascular endothelial cells. MM cells undergoing VM can dedifferentiate into numerous cellular phenotypes and acquire endothelial-like features, resulting in the formation of the de novo matrix-rich vascular-like network, such as plasma and red blood cells. The co-generation of endothelial …
