Unlabelled: Ovarian serous cancer is the most common subtype of epithelial ovarian cancer, and is the leading cause of death from gynecologic cancer. There is an important need for exploration of diagnostic and prognostic markers for this disease. β-catenin and cyclinD1 play central roles in the tumorigenesis for certain cancers. The role of β-catenin and cyclinD1 in diagnosis and prognosis of ovarian serous carcinoma is uncertain. In the present study, the expression of β-catenin and cyclinD1 was examined in 60 ovarian serous carcinomas patients with immunohistochemical staining. The relationship between expression of β-catenin and cyclinD1 and FIGO stage, pathological grade was analyzed. Kaplan-Meier survival function was used to analyze the prognosis. Overexpression of β-catenin is more often detected in patients with FIGO stage III and IV than in those with stage I, and II (P=0.003). No significant relationship was found between expression of β-catenin and pathological grade (P=0.817). Positive expression of β-catenin related to lower survival rate (P=0.034). The expression of cyclinD1 had no relationship with FIGO stage (P=0.829). Overexpression of cyclinD1 was positively to pathological grade (P=0.017) and survival rate (P=0.009). There is a significantly positive relationship between expression of β-catenin and cyclinD1 (P=0.014). No statistical significance was found between expression of β-catenin and cyclinD1 and other pathological parameters.
Conclusions: Expression of β-catenin and cyclinD1 may be used as predict markers for poor prognosis.

Long non-coding RNA LINC01214 is reported to be up-regulated in non-small cell lung cancer (NSCLC), however, its function in NSCLC has not been elucidated yet. In our study, we verified that LINC01214 was aberrantly higher in the tumor tissues and cell lines than that in the normal controls, and was relevant to the severity and prognosis of NSCLC through using real-time quantitative PCR. Then, 3-(4,5)-dimethylthiahiazo (-z-y1)-3,5-di-phenytetrazoliumromide assay and flow cytometry illustrated that knocking down LINC01214 restrained cell proliferation and promoted apoptosis in A549 and H1299 cells.

Objective: To investigate the reversal effect and mechanism of asiatic acid (AA) on multidrug resistance in human adriamycin (ADR) chronic myeloid leukemia K562/ADR cells.
Methods: CCK-8 assay was used to detect the resistance of K562 cells and K562/ADR cells to ADR. CCK-8 assay was used to detect the effect of AA on K562/ADR cell viability and adriamycin sensitization.

Accurate and timely genetic material replication is essential for preserving genomic integrity. The replication process begins with chromatin licensing and DNA replication factor 1 (CDT1). It has been demonstrated that dysregulated CDT1 expression causes genomic instability, damages DNA, and may even cause cancer.

Objective: To explore the antitumor effect of Inonotus obliquus extract on 4T1 tumor-bearing mice in vivo and its possible mechanism.
Methods: 4T1 tumor-bearing mice model was established. After successful modeling, tumor-bearing mice were randomly divided into model control group, cyclophosphamide(CTX) positive group, and high, medium and low dose groups of Inonotus obliquus extract, with 10 mice in each group, which were administered continuously for 21 days.

As a chronic gynecological disease, endometriosis is defined as the implantation of endometrial glands as well as stroma outside the uterine cavity. Proliferation is a major pathophysiology in endometriosis. Previous studies demonstrated a hormone named melatonin, which is mainly produced by the pineal gland, exerts a therapeutic impact on endometriosis.
