MCF7 and SUM149 cells were cultured per American Type Culture Collection (ATCC) recommendations. Primary murine mammary tumor cells were cultured in phenol-free DMEM/F12 (Gibco), with 10% charcoal-stripped FBS (Gibco), 10 μg/ml insulin, and 10 ng/ml EGF. For treatment of estrogen, AZD5363, and 4OHT, tumor cells were cultured in 10% charcoal-stripped FBS in the presence of E2, AZD5363 (ApexBio Technology), 4OHT (Sigma), or dimethyl sulfoxide (DMSO) for the indicated times and then collected for further analysis. To determine cell viability, 50,000 cells were plated in 24-well plates and treated with DMSO or drugs at the indicated concentrations for 5 days. Viable cell numbers were determined on day 1, day 3, and day 5 by an automatic cell counter (Bio-rad) with trypan blue exclusion. For western blot, tissue and cell lysates were prepared as previously reported [19 (link), 23 (link), 37 (link)]. Primary antibodies used are as follows: HSP90 (Santa Cruz), Gapdh (Ambion), ERα (Santa cruz), Brca1, p-Akt (Ser473), p-4E-bp1 (Thr37/46), p-mTor (Ser2248), p-Gsk3β (Ser9), E-cad, Vim, Snail, Slug, p-Fra1 (Ser 265), p-Rb (ser780) (Cell Signaling) and Fn (Abcam).

Astragaloside IV Modulation in Metabolic Pathways

Check if the same lab product or an alternative is used in the 5 most similar protocols
Astragaloside IV (purity ≥ 98%) was obtained from Shanghai Forever Biotech Co., Ltd. (Shanghai, China). Astragaloside IV was dissolved in DMSO to prepare 10 mM stock solution and then was diluted at 1,000-fold in culture medium to generate a working concentration at 10 μM. 0.1% DMSO as a solvent control was run concurrently with the experiments. Palmitate (PA, Sinopharm, Shanghai, China) was dissolved in ethanol to prepare 200 mM stock solution and then further diluted with medium containing 10% FFA-free BSA at the ratio of 1:19 to obtain a concentration of 10 mM before use. Metformin was obtained from Sino-American Shanghai Squibb Pharma (Shanghai, China). Akt inhibitor triciribine, MK2206 and AZD5363 was from Apex Bio (Houston, USA). Isoproterenol was from Shanghai Harvest Pharmaceutical Co., Ltd. (Shanghai, China). TNF-α was from R&D Systems.

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.
