Fourteen of the other potentially secreted proteins appearing at 12 h were common to CIS, LH, and CIS + LH and were found in CTRL only at 24 h (Figure 5 and Figure 6), suggesting accelerated induction by either CIS and LH and no mutual interference, as well as denoting no obvious roles in the present culture system. This evidence concerns the gene PLOD1 and in situ carcinoma.
