Cells were treated with doxycycline (Sigma-Aldrich, #D9891, 200 ng/ml) for 72 h. Total RNA was isolated using SuperPrep Cell Lysis kit (TOYOBO, #SCQ-101) as described by manufacturer and reverse transcribed with SuperPrep RT kit for qPCR (TOYOBO, #SCQ-101) for cDNA synthesis. Target genes were detected by real time PCR in CFX96 Touch™ according to manufacturer's protocol. Transcripts were quantified relative to the housekeeping gene, GAPDH. The probes used for this study were listed in Table S7.

Isolation and Analysis of Bone Cell RNAs

Check if the same lab product or an alternative is used in the 5 most similar protocols
Total RNAs were isolated from cells with RNeasy mini kit (Qiagen, Hilden, Germany) or SuperPrep Cell Lysis Kit (TOYOBO, Osaka, Japan) and bone with TRIzol Reagent (Invitrogen, San Diego, CA). Bone samples were divided into osteoblast- and osteocyte-rich fractions: after bone marrow cells were flushed out with phosphate-buffered saline (PBS), the cells on the endocortical surface were collected as an osteoblast-rich fraction by brushing with an interdental brush in the presence of the TRIzol Reagent. The residual bone pieces were crushed in liquid nitrogen to yield an osteocyte-rich fraction [19 (link)], Isolated RNAs were reverse transcribed using a High capacity cDNA reverse transcription kit (Applied Biosystems, Foster City, CA, USA). For quantitative RT-PCR, samples were analyzed using PowerSYBR Green PCR master mix and an ABI7300 real time PCR system (Applied Biosystems); the primers used are summarized in Supplemental Table 1. The abundance of each target mRNA was normalized by that of Gapdh mRNA.

cDNAs were extracted from HaCaT or A431 cells using SuperPrep Cell Lysis Kit (Toyobo Life Science) following the manufacturer's protocol. QRT-PCR was performed using the primers (as specified in supplemental Table S2) in a 20-µL reaction volume in SYBR Green I Master Mix (Roche) on an ABI StepOne plus QPCR System. GAPDH mRNA was used as an internal control, which was quantified in parallel with mRNAs of the target genes. Normalization and fold changes were calculated by the ΔΔCt method.

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.
