Products are shipped frozen on dry ice in cryotubes. Each cryotube typically contains 3 × 106 cells for adherent lines or 5 × 106 cells for suspension lines (refer to the batch CoA for details).
General information
| Description | The HCC70 cell line is derived from a triple-negative breast cancer (TNBC), a subtype that lacks expression of estrogen, progesterone, and HER2 receptors, making it difficult to treat due to limited targeted therapies. HCC70 cells are notable for their basal-like 1 (BL1) classification within TNBC subtypes, which impacts their response to chemotherapy and treatment strategies. Importantly, HCC70 cells express the G-protein-coupled estrogen receptor GPR30 at significant levels. GPR30 has been associated with rapid signaling responses to estrogens like 17β-estradiol, influencing cell proliferation and other oncogenic pathways. A key genetic characteristic of HCC70 is the presence of a TP53 mutation, specifically the R248Q variant. This mutation is associated with gain-of-function (GOF) phenotypes that contribute to cancer cell survival and aggressive behavior. In studies, R248Q mutation in HCC70 cells has been linked to enhanced cell deformability and altered PARP1 localization, implying potential sensitivity to PARP inhibitors. Research into drug responses in HCC70 and similar TNBC cell lines has highlighted the efficacy of proteasome inhibitors and platinum-based therapies. These treatments have shown promise, with drugs like bortezomib demonstrating cytotoxic effects. The interplay between chemotherapeutic resistance and specific receptor signaling, such as that mediated by GPR30, underscores the complexity of targeting TNBC subtypes like those modeled by HCC70. |

| 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. |
