SNAI1 and neoplasm: These are corroborated by Western blot analyses (Figure 4B,C), where both the tumor-suppressor genes Rb1 and p53 saw a reduction in band intensity in 1–3 days after 222-nanometer far-UVC illumination, whilst phosphor-ERK and its downstream signaling target SNAI1 posted an increase 1–3 days after 222-nanometer exposure.
