Expression and clinical features of hK members in ovarian cancer

hK family member
Location
Expression level and site
Clinical feature
Prognosis

hK4
Tumor cells
Increased in EOC tissue
Predictive marker for paclitaxel resistance[22]
Unfavorable
hK5
Serum, ascites, and tumor extracts [23, 24]
Increased on tumor cells and in serum and ascites
Potential biomarker for diagnosis
Unfavorable
hK6
Tumor cell[26] and serum[25]
High in early-stage and low-grade tumor tissue and in EOC serum
Overexpression is an early phenomenon in the development of ECO; serum level could be used as a biomarker
Unfavorable
hK7
Tumor tissue[27]
High in late-stage EOC
A potential biomarker for diagnosis
Unfavorable
hK8
Tumor extract, serum, and ascites[29]
High in serum and ascites
High level is associated with good prognosis[28, 29]
Favorable
hK9
Tumor cells[30]
High in tumor tissue early-stage and optimal debulking patients
Associated with longer progression-free and overall survival times
Favorable
hK10
Serum[33] and tumor cells[31,32]
High in serum and on tumor cells
High serum level is associated with increased risk for relapse and death; a potential biomarker for diagnosis
Unfavorable
hK11
Serum, ascites[37], and tumor extract [34-36]
Increased in tumor samples
High level is an independent factor for favorable prognosis and is associated with long progression-free and overall survival times and with slower disease progression[34, 35]; however, high level is also associated with poor survival rate[36].
Depends
hK13
Tumor tissue[38]
verexpressed in tumor tissue
Associated with longer progression-free and overall survival times
Favorable
hK14
Tumor cells[41] and serum[40]
Increased in tumor tissue and serum
Associated with longer progression-free and overall survival times; an independent prognostic factor
Favorable
hK15
Tumor extract[42]
Increased in tumor tissue
Associated with short progression-free and overall survival times; an independent prognostic factor
Unfavorable
