The ratios of the Raman signals at 2850 (S2850, reflecting the lipid content) and 2928 cm−1 (S2928, reflecting the protein contents) were markedly increased in CRC cells (DLD‐1 and SW480) after EBV‐miR‐BART18‐3p OEX, FASN OEX, or hypoxic treatment, whereas this effect was abrogated by EBV‐miR‐BART18‐3p KD or FASN KD (Figure 5L,M and Figure S12, Supporting Information). The gene discussed is FASN; the disease is colorectal carcinoma.
