hA1 and hA3 AR functional experiments were carried out in CHO-A1 and CHO-A3#18 cell line, respectively. The day before the assay, the cells were seeded on the 96-well culture plate (Falcon 353072). The cells were washed with wash buffer (Mixture F12 Ham’s (Sigma N6658) for hA1 AR; Dulbecco’s modified eagle’s medium nutrient mixture F-12 ham (Sigma D8062) for hA3 AR; 25mM Hepes; pH = 7.4). Wash buffer was replaced by incubation buffer (Mixture F12 Ham’s (Sigma N6658) for hA1 AR; Dulbecco’s modified eagle’s medium nutrient mixture F-12 ham (Sigma D8062) for hA3 AR; 25 mM Hepes, 20 µM Rolipram (Sigma R6520); pH = 7.4). The cells were pre-incubated at 37 °C for 15 min. Then, test compounds and 5′-(N-Ethilcarboxamido) adenosine (NECA) as reference compound (Sigma E2387) were added and incubated at 37 °C for 10 min. FSK (Sigma F3917) was added and incubated at 37 °C for 5 min. After incubation, the amount of cAMP was determined using cAMP Biotrak Enzyme immunoassay (EIA) System Kit (GE Healthcare RPN225).

SKN, which is a human uLMS cell line, and MES-SA, which is human uterine sarcoma cell line, were used in this study. SKN was purchased from Health Science Research Resources Bank (HSRRB, Osaka, Japan), and MES-SA was purchased from American type culture collection (ATCC, Virginia, USA). SKN cells were cultured in Ham's F 12 (Sigma-Aldrich Japan K.K., Tokyo, Japan), and MES-SA cells were cultured in McCoy's 5a medium (ATCC). Both media were supplemented with 10% heat-incubated fetal bovine serum (FBS). The cells were seeded at a density of 5×104 cells/well in a six-well plate, and incubated at 37°C in a humidified 5% CO2 incubator for 5 days. The cells were trypsinized and counted by a cell counter (Vi-CELL XR; Beckman Coulter, Tokyo, Japan) at each time point, as reported previously (36 (link)).
For TGF-β treatment, cells were cultured in Ham's F12 and McCoy's 5a medium supplemented with 10% FBS containing 100 or 500 pg/ml TGF-β1 (Sigma-Aldrich Japan K.K.) for 24 h. In order to block TGF-β signaling, SB431542 (WAKO, Tokyo, Japan), which is a TGF-β type I receptor-selective blocker, was dissolved at a concentration of 10 µM in dimethylsulfoxide (DMSO). Cells were seeded at a density of 5×104 cells/well in a six-well plate and cultured for 24 h and then cultured with new medium supplemented with 10 µM SB431542 for more 48 h.

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.
