General information
| Description | The LxF-289 cell line is a human lung adenocarcinoma cell line established from a 63-year-old male patient. This cell line has a doubling time of approximately 50 hours, making it suitable for studies that require consistent cell proliferation. LxF-289 is particularly valuable in research focused on lung cancer, especially non-small cell lung cancer (NSCLC), as it provides a robust in vitro model for studying the molecular mechanisms underlying cancer progression, treatment resistance, and the effects of therapeutic interventions. Studies on LxF-289 have demonstrated that this cell line exhibits characteristics that make it responsive to specific genetic and therapeutic manipulations. For instance, research has shown that LxF-289, along with other lung cancer cell lines, can undergo significant cell death when treated with an adenovirus expressing antisense heat shock protein 70 (Hsp70). This cell death is p53-independent and does not require DNA cleavage, suggesting that Hsp70 plays a crucial role in the survival of lung cancer cells. Notably, this response is selective to cancer cells, as normal lung fibroblasts and bronchial epithelial cells do not show similar levels of cytotoxicity when Hsp70 is downregulated, highlighting the potential of targeting Hsp70 in lung cancer therapy. Moreover, LxF-289 has been used to study the effects of irradiation on drug resistance-related proteins. The cell line exhibited overexpression of glutathione S-transferase (GSTπ) at both mRNA and protein levels following irradiation. This overexpression is associated with the development of multidrug resistance, which is a significant challenge in the clinical management of lung cancer. These findings underscore the utility of LxF-289 in exploring the mechanisms of resistance and testing novel strategies to overcome it. |

Handling
| Culture Medium | RPMI 1640, w: 2.0 mM stable Glutamine, w: 2.0 g/L NaHCO3 (Cytion article number 820700a) |
|---|---|
| Supplements | Supplement the medium with 10% FBS |
| Dissociation Reagent | Accutase |
| Subculturing | 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. |
| Seeding density | 1 x 104 cells/ml |
| Fluid renewal | Every 3 to 5 days |
| Post-Thaw Recovery | 24 to 48 hours |
| Freeze medium | As a cryopreservation medium, we use complete growth medium (including FBS) + 10% DMSO for adequate post-thaw viability, or CM-1 (Cytion catalog number 800100), which includes optimized osmoprotectants and metabolic stabilizers to enhance recovery and reduce cryo-induced stress. |
| Thawing and Culturing Cells |
|
| Incubation Atmosphere | 37°C, 5% CO2, humidified atmosphere. |
| Shipping Conditions | 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. |
| Storage Conditions | 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. |
Quality Control & Molecular Analysis
| Sterility | 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. |
