Summary

Eukaryotic translation initiation factor 3, subunit A (eIF3a) and human epididymis protein 4 (HE4) expression levels are significantly altered in ovarian cancer tissues. These proteins show a positive correlation, suggesting their involvement in ovarian cancer development.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Ovarian cancer is a significant global health concern.
  • Identifying novel biomarkers for early detection and understanding disease mechanisms is crucial.

Purpose of the Study:

  • To investigate the correlation between eukaryotic translation initiation factor 3, subunit A (eIF3a) and human epididymis protein 4 (HE4) expression in ovarian cancer.
  • To analyze the differential expression of eIF3a and HE4 in normal, benign, and malignant ovarian tissues.

Main Methods:

  • RT-PCR and immunohistochemistry were employed to assess eIF3a and HE4 mRNA and protein levels.
  • Analysis included 181 ovarian cancer patients, patients with benign ovarian tumors, and healthy women.

Main Results:

  • Significant differences in eIF3a and HE4 mRNA and protein expression were observed across normal, benign, and ovarian cancer tissues (P<0.05).
  • HE4 mRNA expression increased progressively from normal to benign to cancer tissues, while eIF3a mRNA was highest in normal tissues.
  • eIF3a and HE4 protein expression levels were significantly higher in cancer tissues compared to normal and benign tissues, with a positive correlation between eIF3a and HE4 protein expression (r=0.575, P<0.05).

Conclusions:

  • Both eIF3a and HE4 expression are associated with the development of ovarian cancer.
  • Extracellular regulated protein kinases may mediate the interaction between eIF3a and HE4 in ovarian cancer.
