In KLK6-high group, we observed a particularly high KLK10 co-expression, followed by KLK7 and KLK8. We also noted that KLK10 transcript levels were significantly higher than KLK6, KLK7, and KLK8 in normal tissues (Figure 1A), and KLK10 was elevated in tumor samples in KLK6-low group but to a lesser degree than in KLK6-high samples (Figure 1B2). Here, KLK10 is linked to neoplasm.
