Check if the same lab product or an alternative is used in the 5 most similar protocols
Mouse HT22 hippocampal cells were cultured in DMEM medium (GE Healthcare Life Sciences, Logan, UT, USA) containing 10% (v/v) fetal calf serum (FBS) and 0.35% glucose and supplemented with duplex antibiotics of 100 U/mL penicillin and 100 μg/mL streptomycin, in a humidified atmosphere of 5% CO2 and 95% air at 37°C. The APN peptide was dissolved in dimethyl sulfoxide (DMSO) and diluted with culture medium immediately prior to use. DMSO (0.01%) was used as a sham control. The cells were pretreated with different concentrations of the APN peptide for 6 h before being exposed to Glu. The concentrations and durations of Glu exposure in the Glu group were selected based on a previous study [30 (link)]. After relevant treatments, cells were collected for further analysis.

Sumac Extract's Effects on Breast Cancer Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
In the in vitro experiments, human breast cancer cell lines MCF-7 (ER+, PR+, HER2−), MDA-MB-231 (ER− PR−, HER2−) and non-cancer MCF-10A (human mammary gland epithelial cells) were used. Breast cancer cells were cultured in DMEM medium (GE Healthcare, Piscataway, NJ, USA) or RPM1 1640 medium (Biosera, Kansas City, MO, USA) and non-cancer cells were cultured in DMEM F12 medium (Biosera, Kansas City, MO, USA) + supplemented with insulin, EGF- epithelial growth factor, HC-hydrocortisone (all Sigma, Steinheim, Germany). The growth medium was supplemented with 10% FBS (Gibco), antibiotic/antimycotic solution (1× HyClone™; GE Healthcare, Chicago, IL, USA) and cells were cultivated in an atmosphere containing 5% CO2 in humidified air at 37 °C. Before each experiments, the cell viability was estimated by trypan blue exclusion (≥95%).
For the flow cytometry experiments, the MCF-7 (3 × 105) and MDA-MB-231 (1 × 105) cells were seeded in Petri dishes and cultivated for 24 h in a complete cultivation medium. The sumac extract (SONNENTOR Kräuterhandels GMBH, Sprögnitz, Austria) was added to every experimental group for 24, 48, and 72 h prior to analysis.

Inducible DDX39B Overexpression in HeLa Cells

Check if the same lab product or an alternative is used in the 5 most similar protocols
HeLa cells stably expressing an inducible DDX39B cDNA trans-gene were generated using the Flp-In T-Rex system (Life Technologies) as recommended by the manufacturer. HeLa Flp-In T-Rex cell line (Kaiser et al., 2008 (link)) was kindly provided to our group by Dr. E Dobrikova (Duke University). The coding sequence of DDX39B was amplified with Phusion High-Fidelity DNA polymerase (New England BioLabs) using as template cDNA prepared from total RNA isolated from human PBMCs. Forward and reverse primers contained HindIII and XhoI restriction sites, respectively. The resulting PCR amplicon was cloned into pcDNA5/FRT/TO plasmid using HindIII and XhoI restriction sites and verified by Sanger sequencing. This plasmid was co-transfected with pOG44 plasmid, which encodes the Flp recombinase, into HeLa Flp-In T-Rex cells using Lipofectamine 2000 (Life Technologies) according to the manufacturer’s instructions. Transfected cells were grown in DMEM medium supplemented with 10% FBS free of tetracycline (GE Healthcare Life Sciences) under blasticidin/hygromycinB selection for 15 days, and resistant cells were expanded and used for subsequent experiments. Expression of the trans-gene was induced by addition of tetracycline at 50 μg/ml.

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.
