PLOD1 and in situ carcinoma: The greatest differences in number were detected in the comparisons between CIS + LH vs. LH (16 proteins at 2 h, 10 at 12 h, and 20 at 24 h) and CIS + LH vs. CIS (18 at 2 h, 12 at 12 h, and 13 at 24 h), while minor differences were detected in the comparison between LH vs. CIS + LH (0 at 2 h, 7 at 12, h and 8 at 24 h) (Figure 6 and Figure S2a–c).
