Background of CHOK1-cyno-ACVR1C-Cell-Line

The Activin A Receptor Type 1C (ACVR1C), also known as ALK-7, belongs to the transforming growth factor-beta (TGF-β) superfamily of serine/threonine kinase receptors. ACVR1C plays a significant role in various biological processes, including cell proliferation, differentiation, and apoptosis by mediating signals from activin A, a cytokine involved in numerous physiological functions. Research has indicated that ACVR1C is implicated in metabolic regulation, immune responses, and embryonic development. Dysregulation or mutations in this gene have been linked to several diseases, such as polycystic ovary syndrome (PCOS) and cancer.

Cell Resuscitation

1. Prewarm culture medium (RPMI 1640 supplemented with 10% FBS and 10μg/mL puromycin)in a 37°C water bath.
2. Thaw the frozen vial in a 37°C water bath for 1-2 minutes.
3. Transfer the vial into biosafety cabinet, and wipe the surface with 70% ethanol.
4. Unscrew the top of the vial and transfer the cell suspension gently into a sterile centrifuge tube containing 9.0mL complete culture medium.
5. Spin at ~ 125 × g for 5-7 minutes at room temperature, and discard the supernatant without disturbing the pellet.
6. Resuspend cell pellet with the appropriate volume of complete medium and transfer the cell suspension into a T25 culture flask.
7. Incubate the flask at 37°C, 5% CO₂ incubator.
8. Split saturated culture 1:6-1:8 every 2-3 days; seed out at about 1-3 × 10⁵ cells/mL.

Cell Freezing

1. Prepare the freezing medium (70% RPMI 1640 + 20% FBS + 10% DMSO) fresh immediately before use.
2. Keep the freezing medium on ice and label cryovials.
3. Transfer cells to a sterile, conical centrifuge tube, and count the cells.
4. Centrifuge the cells at 250×g for 5 minutes at room temperature and carefully aspirate off the medium.
5. Resuspend the cells at a density of at least 3×10⁶ cells/mL in chilled freezing medium.
6. Aliquot 1 mL of the cell suspension into each cryovial.
7. Freeze cells in the CoolCell freezing container overnight in a -80°C freezer.
8. Transfer vials to liquid nitrogen for long-term storage.
