Abstract

The present study aimed to investigate the expression levels of microRNA (miR)-23a and miR-23b in the tumor tissues of patients with ovarian cancer. The study also explored the correlation of miR-23a and miR-23b expression levels in the tumor tissues with the clinic-pathological parameters and prognosis of the patients. Specimens of frozen tumor tissues and normal tissues adjacent to the tumor were collected from 50 patients with ovarian cancer. Reverse transcription-quantitative polymerase chain reaction was adopted to detect the expression levels of miR-23a and miR-23b in tumor tissues. Furthermore, normal tissues adjacent to the tumor were utilized as the control for the experiments and Pearson method was used to analyze the correlation between miR-23a and miR-23b expression levels in tumor tissues. The correlation of miR-23a and miR-23 expression in tumor tissues and the prognosis of the patients with ovarian cancer was analyzed in combination with clinical data. The expression of miR-23a in the tissues of ovarian cancer was significantly higher in comparison with normal adjacent tissues. However, the expression of miR-23b in the tissues of ovarian cancer was significantly lower when compared with adjacent normal tissues. Notably, the expression of miR-23a was negatively correlated with that of miR-23b in tumor tissues of ovarian cancer. The high expression of miR-23a and the low expression of miR-23b in tumor tissues of the patients was correlated with the degree of tumor differentiation, metastasis of lymph nodes and clinical staging. The five-year overall survival rate of the patients was 36% (18/50). Univariate survival analysis indicated that miR-23a and miR-23b were the factors influencing the overall survival rate of ovarian cancer. The present findings suggest that high expression of miR-23a and the low expression of miR-23b are closely correlated with the occurrence and development of ovarian cancer. The abnormal expression of the miR-23a and miR-23b could be utilized as potential prognostic molecular markers of ovarian cancer.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • High expression of miR-23a and low expression of miR-23b both determine the occurrence and progression of ovarian cancer.

    “the high expression of miR-23a and the low expression of miR-23b both determine the occurrence and progression of OC [86].”

    From Recent advances of miR-23 in human diseases and growth development (2025) · cites this paper as [86]

    The Results report higher miR-23a and lower miR-23b expression in ovarian tumors and associations with differentiation, lymph-node metastasis, and clinical stage. The Abstract says these expression patterns are ‘closely correlated’ with occurrence and development; it does not establish that they determine either one. Page numbers were not provided in our copy.

    Experimental — accuracy not yet measured
  • In tumor tissues of 50 ovarian cancer patients, expression levels of miR-23a/b were not identical in relation to clinical pathological parameters and prognosis, suggesting functional divergence among family members.

    “in the tumor tissues of 50 patients with ovarian cancer (OC), researchers found that the expression levels of miR-23a/b were not identical in relation to the clinical pathological parameters and prognosis, suggesting there is a functional divergence among different family members.”
  • Expression of miR-23a is negatively correlated with expression of miR-23b in ovarian cancer.

    “the expression of miR-23a is negatively correlated with the expression of miR-23b.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
