Sphingosine Kinase 1/SPHK1 in HepG2 and U266 Human Cell Lines. Sphingosine Kinase 1/SPHK1 was detected in immersion fixed HepG2 human hepatocellular carcinoma cell line (positive stain) and U266 human myeloma cell line (negative stain) using Mouse Anti-Human Sphingosine Kinase 1/SPHK1 Monoclonal Antibody (Catalog # MAB55361) at 8 µg/mL for 3 hours at room temperature. Cells were stained using the NorthernLights™ 557-conjugated Anti-Mouse IgG Secondary Antibody (red; Catalog # NL007) and counterstained with DAPI (blue). Specific staining was localized to nuclei and cytoplasm. View our protocol for Fluorescent ICC Staining of Cells on Coverslips.

Background: Sphingosine Kinase 1/SPHK1

Sphingosine kinases are cytosolic or membrane‑associated enzymes that catalyze the phosphorylation of sphingosine to sphingosine‑1‑phosphate (S1P). Two types of sphingosine kinases, SPHK1 and SPHK2, are known to be expressed in human cells. The two enzymes share considerable amino acid sequence similarity, but differ in their N‑terminal and central regions (1). The two proteins also differ in tissue distribution and some kinetic properties (1). S1P is a lipid messenger that regulates diverse physiological processes including cell proliferation, migration, apoptosis, inflammation, calcium homeostasis and cytoskeletal structure (2, 3). The level of S1P is tightly controlled by SPHKs and S1P degrading enzymes. SPHK1 and its activation can be stimulated by several growth factors such as tumor necrosis factor-alpha, epidermal growth factor and transforming growth factor-beta (3, 4). Expression of SPHK1 has been found to increase in many human solid tumors and overexpression of SPHK1 is associated with tumor angiogenesis (5). Such studies have implicated SPHK1 as a new target for cancer treatment.
