Bapta-AM (BAP 10 μM) and YM201636 (YM 1 μM) and also controls Hydroxycloroquine (HCL 10 μM) endosomal acidification inhibitor and Teicoplanin (TEI 10 μM), an inhibitor of cathepsin L (Zhou et al., 2016 (link)) were purchased from Abcam. Stock solutions were dissolved in DMSO and working solutions were freshly prepared in DMEM 2% fetal bovine serum (FBS) at indicated concentrations. First, we pursued cell viability and cytotoxicity tests of all reagents using the CellTiter 96 Non-radioactive Cell Proliferation Assay (Promega) following the Manufacturer's instructions (Supplementary Fig. S2, Supplementary Fig. S3, Supplementary Fig. S4). We also studied the cytotoxic activity of the organic solvent DMSO. Based on these experiments we selected optimal non-toxic working concentrations for infection assays.

Tamoxifen, Raloxifene, and Estradiol Effects in Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
All animal experiments were conducted according to IACUC guidelines. Two-month-old (20 females 20 males) C57B6 (subtype) were purchased from Jackson laboratories and housed in Mt. Sinai’s vivarium under standard conditions. Animals (females n = 4, males n = 4) received twice daily subcutaneous injections on the upper back (2.5 mg/kg) of tamoxifen (Sigma part number T5648-1G), raloxifene hydrochloride (Sigma part number R1402-1G), β-estradiol (Sigma part number E8875-250MG), or vehicle (5% dimethylsulfoxide in vegetable oil) alone twice daily for 3 consecutive days. Animals were sacrificed on the fourth day when tissue was harvested and flash frozen.
Spinal cords were isolated by hydraulic extraction, minced with forceps, and flash frozen for later analysis. Tissue was lysed in NP40 lysis buffer (50 mM Tris, 250 mM NaCl, 5 mM EDTA, 0.5% NP-40, 50 mM NaF, 1 mM dithiothreitol plus protease inhibitors) on ice with roughly a 1:3 volume to volume ratio of tissue powder to lysis buffer. All samples were subjected to probe sonication (Fisher Scientific FB505) with 2 to 3 rounds of 1-second intervals at 20% amplitude on ice. Protein was then cleared by spinning at 20 800g at 4°C for 20 minutes. The soluble fraction was then moved to a new tube and frozen at –20°C for later analysis.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Fifty-four 10-week-old Sprague-Dawley female rats (Oriental Biotech, Pyeongtaek, Republic of Korea) were raised at room temperature (25 ± 1℃) with a relative humidity of 55% and a circadian light rhythm of 12 h. They were randomly assigned into three groups: two experimental groups and one control group; raloxifene (RAL)-administered group (n = 18) for ovariectomized rats administered with raloxifene, ovariectomy (OVX) group (n = 18) for ovariectomized without raloxifene treatment and the control group (n = 18) for rats that underwent a sham operation. For the RAL group, 1 mg/kg/day of raloxifene hydrochloride (Sigma-Aldrich, St. Louis, MO, USA) was dissolved in dimethylsulfoxide and was directly administered into the rats' stomach through gavage from day one after implant placement. The same amount of 0.9% normal saline was administered to rats in the OVX and the control groups (Fig. 1). All animal handling and surgical procedures were approved by the Institutional Ethical Committee for Animal Care and Use (BSM 16-001).

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.
