NMT2 and squamous cell carcinoma: Real-time quantitative PCR (qPCR) revealed that NMT1 mRNA levels were significantly elevated under hypoxia in three hypoxia-responsive squamous cell carcinoma cell lines (SCC9, SIHa, and KYSE-510) [10], whereas NMT2 levels remained unchanged (Fig. 1G and Fig S1A-B).
