Información general
| Descripción | The SK-N-LO cell line is a human neuroblastoma cell line used in research to study neuroblastoma as well as mechanisms of apoptosis and cancer signaling pathways. It is also classified as a primitive neuroectodermal tumor (PNET) cell line and carries the EWS-FLI1 fusion gene, commonly found in Ewing's sarcoma family tumors (ESFT). This fusion gene results from a chromosomal translocation and plays a key role in the oncogenic behavior of these tumor cells. SK-N-LO cells are particularly sensitive to certain inhibitors targeting oncogenic signaling pathways. For example, the GLI inhibitor GANT61 has been shown to induce caspase-independent apoptosis in SK-N-LO cells. GANT61 disrupts GLI1 and GLI2-mediated transcription in the Hedgehog (Hh) signaling pathway, which is critical for cell survival and proliferation in this cell line. When treated with GANT61, SK-N-LO cells exhibit morphological changes associated with apoptosis, such as chromatin condensation and nuclear fragmentation. Furthermore, GANT61 reduces the expression of proteins like GLI2 and survivin, which are important for cell cycle progression and survival, while increasing the expression of p21, a cyclin-dependent kinase inhibitor. Additionally, SK-N-LO cells have been utilized to study opioid receptor signaling. These cells have been engineered to express the μ-opioid receptor, making them a valuable model for investigating the interaction between opioid-induced analgesia and intracellular signaling pathways. For instance, studies have shown that morphine stimulates Akt phosphorylation in SK-N-LO cells via the PI3Kγ pathway, a process that can be modulated by cAMP signaling. This highlights the versatility of SK-N-LO cells in exploring both cancer biology and neuropharmacology. |

Manejo
| Medio de cultivo | EMEM (MEM Eagle), w: 2 mM L-Glutamine, w: 2.2 g/L NaHCO3, w: EBSS (Cytion article number 820100a) |
|---|---|
| Suplementos | Supplement the medium with 10% FBS and 1% NEAA |
| Reactivo de disociación | Accutase |
| Subcultivo | Remove the old medium from the adherent cells and wash them with PBS that lacks calcium and magnesium. For T25 flasks, use 3-5 ml of PBS, and for T75 flasks, use 5-10 ml. Then, cover the cells completely with Accutase, using 1-2 ml for T25 flasks and 2.5 ml for T75 flasks. Let the cells incubate at room temperature for 8-10 minutes to detach them. After incubation, gently mix the cells with 10 ml of medium to resuspend them, then centrifuge at 300xg for 3 minutes. Discard the supernatant, resuspend the cells in fresh medium, and transfer them into new flasks that already contain fresh medium. |
| Densidad de siembra | 3 to 4 x 104 cells/cm2 |
| Renovación de fluidos | 2 to 3 times per week |
| Medio de congelación | As a cryopreservation medium, we use 50% basal medium + 40% FBS + 10% DMSO, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. |
| Descongelación y cultivo de células |
|
| Atmósfera de incubación | 37°C, 5% CO2, humidified atmosphere. |
| Condiciones de envío | Cryopreserved cell lines are shipped on dry ice in validated, insulated packaging with sufficient refrigerant to maintain approximately −78 °C throughout transit. On receipt, inspect the container immediately and transfer vials without delay to appropriate storage. |
| Condiciones de almacenamiento | For long-term preservation, place vials in vapor-phase liquid nitrogen at about −150 to −196 °C. Storage at −80 °C is acceptable only as a short interim step before transfer to liquid nitrogen. |
Control de calidad y análisis molecular
| Esterilidad | Mycoplasma contamination is excluded using both PCR-based assays and luminescence-based mycoplasma detection methods. To ensure there is no bacterial, fungal, or yeast contamination, cell cultures are subjected to daily visual inspections. |
