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.

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
Fluid renewal	2 to 3 times per week
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	Confirm that the vial remains deeply frozen upon delivery, as cells are shipped on dry ice to maintain optimal temperatures during transit. Upon receipt, either store the cryovial immediately at temperatures below -150°C to ensure the preservation of cellular integrity, or proceed to step 3 if immediate culturing is required. For immediate culturing, swiftly thaw the vial by immersing it in a 37°C water bath with clean water and an antimicrobial agent, agitating gently for 40-60 seconds until a small ice clump remains. Perform all subsequent steps under sterile conditions in a flow hood, disinfecting the cryovial with 70% ethanol before opening. Carefully open the disinfected vial and transfer the cell suspension into a 15 ml centrifuge tube containing 8 ml of room-temperature culture medium, mixing gently. Centrifuge the mixture at 300 x g for 3 minutes to separate the cells and carefully discard the supernatant containing residual freezing medium. Gently resuspend the cell pellet in 10 ml of fresh culture medium. For adherent cells, divide the suspension between two T25 culture flasks; for suspension cultures, transfer all the medium into one T25 flask to promote effective cell interaction and growth. Adhere to established subculture protocols for continued growth and maintenance of the cell line, ensuring reliable experimental outcomes.
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.

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.
