HeLa (ATCC, CCL-2, RRID: CVCL0030), U2OS (ATCC HTB-96, RRID:CVCL0042), H2030 (ATCC CRL-5914, RRID:CVCL1517), and HCC827 (ATCC CRL-2868, RRID:CVCL2063) were purchased from ATCC. HEKT293 (Thermo R70007, RRID: CVCL6911) were purchased from Thermo Scientific. HeLa and U2OS cells were cultivated in Dulbecco’s Modified Eagle’s Medium (Biochrom), containing 10% fetal calf serum, 2 mM L-glutamine, and 100 U penicillin/streptomycin. H2030, HCC827: RPMI 1640 Medium, containing 10% fetal calf serum, 2 mM L-glutamine, and 100 U penicillin/streptomycin. HEK T293: DMEM GlutaMAX™ Medium, containing 10% fetal calf serum and 100 U penicillin/streptomycin. All cell lines were tested negative for mycoplasma contamination. Cell line data were collected from Cancerrxgene (Wellcome Sanger Institute) and RNA-Seq data were obtained from Klijn et al.21 (link).
For heat stress induction, cells were incubated at 44 °C with 5% CO2. Preliminary experiments in HeLa cells and U2OS cells revealed no substantial difference between 42 °C for 4 h and 44 °C for 1 h on RNA level in our hands13 (link). Thus, the latter conditions were applied for subsequent experiments, as they induced SatIII foci in a comparable or even stronger fashion.

All LUAD cell lines (A549, Calu-1, H1792, H2030, MOR, and SW1573) used in this study were obtained from ATCC or Sigma-Aldrich (MOR only). The 634T cells were a generous gift from the laboratory of Kwok Wong (NYU). Cells were cultured in Roswell Park Memorial Institute (RPMI)-1640 (Corning 10-040-CV) supplemented with penicillin–streptomycin and 10% fetal bovine serum. Spheroids were grown in medium supplemented with methylcellulose (Thermo Fisher Scientific M352-500). To prepare 100 mL of methylcellulose-containing medium, 1.2 g of methylcellulose was autoclaved in a bottle containing a stir bar. One hundred ml of medium was warmed to 37 °C and then added to the methylcellulose. The methylcellulose medium was then shaken vigorously and allowed to dissolve at 4 °C overnight, with stirring. Cells were maintained at 37 °C in a humidified incubator containing 5% CO2. All cell lines (and their derivatives) were confirmed to be mycoplasma-free using the MycoAlert mycoplasma detection kit (Lonza LT07-218) at the beginning and upon completion of all experiments.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
