The objective of the study was to explore the role ofcalgranulin Bgene on the biological behavior of squamous cervical cancer.
Differential transcription incalgranulin Bgene between human papillomavirus (HPV)-positive and negative cervical cancer groups was identified, and the relationship betweencalgranulin Bgene andmatrix metalloproteinase(MMP) genes were explored using The Cancer Genome Atlas database. Subsequently, the role of calgranulin B on the cell proliferation, apoptosis, invasion and migration was investigated, through overexpression and/or underexpression of calgranulin B in cervical cancer cells. In addition, the effect of calgranulin B on the growth of the cervical cancer was studied via constructing xenograft model in BALB/c nude mice that either overexpressed or underexpressed calgranulin B.
Calgranulin B
gene transcription in cervical cancer was highly correlated with the high-risk HPV-16 and HPV-45. In addition, overexpression of calgranulin B increased cell proliferation, invasion and migration, whereas it did not significantly affect cell apoptosis. This effect was also confirmed by calgranulin B knockdown assay. Additionally, we found that the transcription ofcalgranulin Bgene was negatively correlated withMMP15andMMP24genes, but positively associated withMMP25genes in cervical cancer. Furthermore, calgranulin B significantly promoted the growth of cervical cancer in vivo.
Calgranulin B promotes cell proliferation, migration and invasion of squamous cervical cancer, possibly via regulation of MMPs. Whether there are synergistic actions between calgranulin B and HPV-16/HPV-45 infection on the squamous cervical carcinogenesis or progression need further study.
