Protocols for Culturing and Transfecting Ovarian and Breast Cancer Cell Lines

Check if the same lab product or an alternative is used in the 5 most similar protocols
All cell lines were maintained in 5% CO2 at 37°C. Ovarian cancer (A2780, OVCAR3, SKOV3, OVCA432, HeyA8, IGROV, EG) and breast cancer (MDA-MB-231, MCF7, GILM2) cells were obtained from the American Type Culture Collection and were maintained in RPMI 1640 supplemented with 10–15% fetal bovine serum (FBS) and 0.1% gentamicin sulfate (GeminiBioproducts, Calabasas, CA). All cell lines were routinely tested to confirm the absence of Mycoplasma, and all in vitro experiments were conducted with 60–80% confluent cultures.
All siRNA transfections (Supplementary Table 1) were performed using RNAi MAX (Invitrogen Carlsbad, CA) reagent using forward transfection protocol from the manufacturer. Media was changed 5 hours after transfections to minimize toxicity. For all hypoxia treatments, cells were incubated in an oxygen-controlled hypoxia chamber at 1% O2. For ectopic expression of Drosha and Dicer, we obtained plasmids from Addgene (IDs 10828, 25851 respectively). Next, we cloned open reading frames into pLKO.1-GFP or Puromycin lentiviral plasmids. We transduced HeyA8 cells with virus particles and then selection using GFP (Drosha) or puromycin (Dicer) was carried out to establish stable cell variants.

Cytotoxicity of M. mabokeensis Bark Extracts

Check if the same lab product or an alternative is used in the 5 most similar protocols
The cytotoxicity of the different M. mabokeensis Aubrév bark extracts was estimated on IGROV and OVCAR cells lines (American Type Culture Collection) as described by Kohoude et al. [14 (link)], with minor modifications. Cells were distributed in 96-well plates at 3 × 104 cells/well in 100 μL. After that, 100 μL of the corresponding culture medium (DMEM) containing sample at various concentrations was added. Cell growth was estimated by the MTT assay. MTT is a water-soluble tetrazolium salt with a yellow coloration. Metabolically active cells are able to convert the dye to water-insoluble dark blue formazan by reductive cleavage of the tetrazolium ring. The extracts were resolubilized in the DMSO followed by dilution in the buffer, whereby the DMSO does not exceed 1%. Doxorubicin was used as a positive control. The cells activity inhibition percentage was calculated as follows: % inhibition=100×AblankAsampleAblank.

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.
