Overexpression vector for M1AP with a doxycycline-inducible vector confirmed that M1AP induced high MYC expression by real-time quantitative PCR

A pTRIPZ-M1AP-GFP, doxycycline-inducible lentiviral vector, was induced HEK293T cells and RNA was isolated using an RNeasyR Mini Kit (Qiagen) according to the manufacturer’s instructions. Complementary DNA (cDNA) was generated from RNA with ReverTra AceR qPCR RT Master Mix (Toyobo). Beta-ACTIN was used as an endogenous control. Using the ABI Prism 7900HT (Applied Biosystems), quantitative PCR (qPCR) analysis was performed to quantify the RNA level using SYBR Mix. The sequences for the PCR primers used in gene expression were as follows: MYC: 5′-CGACTCTGAGGAGGAACAAGAA-3′ (forward) and 5′-CAGCAGAAGGTGATCCAGACT-3′ (reverse), β-ACTIN: 5′-CACAGAGCCTCGCCTTTGCC-3′ (forward) and 5′-CACAGAGCCTCGCCTTTGCC-3′ (reverse). The mRNA level of the targeted gene was analyzed by comparison with the standard calibration curve.
