Figure 8B showsaverage normalized Raman spectra of membranes and mitochondria inbreast cancer cells (HTB-30) (A), triple-positive HER2MCF-7 (B), HTB-30,and AU-565 (C) overexpressing HER2, the normal cells (MCF-10A) (HER2at the normal level), and triple -negative aggressive breast cancer(MDA-MB-231). The gene discussed is ERBB2; the disease is cancer.
