(Invitrogen Life Technologies) and reverse transcribed using Thermo Scientific
Revert Aid First Strand cDNA Synthesis Kit (Thermo Scientific, Waltham, MA,
U.S.A.) according to the manufacturer's instructions. qRT-PCR was carried
out with FastStart Universal SYBR Green Master (Rox) (Roche FastStart Universal
SYBR Green Master (Rox) (Roche Applied Science, Mannheim, Germany) on an ABI
Prism 7900 Fast instrument (Applied Biosystems, Foster City, CA, U.S.A.).
Reactions were performed in triplicate.
Primers for qRT-PCR reactions were as follows: human IL-6R, forward
5′-TTCTACAGACTACGGTTTGAG-3′ and reverse
5′-GGATGACACAGTGATGCT-3′; human IL-6ST, forward
5′-ACTGTTGATTATTCTACTGTGTAT-3′ and reverse
5′-AATTATGTGGCGGATTGG-3′; human BCL2, forward
5′-GATGACTGAGTACCTGAACC-3′ and reverse
5′-AGTTCCACAAAGGCATCC-3′; human CCND1, forward
5′-CGGAGGAGAACAAACAGA-3′ and reverse
5′-GCGGATTGGAAATGAACTT-3′; human MCL1, forward
5′-CAGGATTGTGACTCTCATT-3′ and reverse
5′-CCTCTACATGGAAGAACTC-3′; human MMP2, forward
5′-ACAAGAACCAGATCACATACAG-3′ and reverse
5′-TCACATCGCTCCAGACTT-3′; human GAPDH, forward
5′-GTCAAGGATTTGGTCGTATT-3′ and reverse
5′-AGTCTTCTGGGTGGCAGTGAT-3′. Then, the mRNA level of
IL-6R, IL-6ST, BCL2, CCND1, MCL1, and MMP2genes was normalized to GAPDH mRNA and expressed by
2−ΔΔCT(ΔΔCt, the relative cyclic value)
