Inhibition of AXL enhances chemosensitivity of human ovarian cancer cells to cisplatin via decreasing glycolysis.

Anexelekto (AXL), a member of the TYRO3-AXL-MER (TAM) family of receptor tyrosine kinases (RTK), is overexpressed in varieties of tumor tissues and promotes tumor development by regulating cell proliferation, migration and invasion. In this study, we investigated the role of AXL in regulating glycolysis in human ovarian cancer (OvCa) cells. We showed that the expression of AXL mRNA and protein was significantly higher in OvCa tissue than that in normal ovarian epithelial tissue.

circCELSR1 facilitates ovarian cancer proliferation and metastasis by sponging miR-598 to activate BRD4 signals.

Background: Ovarian cancer is one of the most common gynecologic cancers and has high mortality rate due to the lack of early diagnosis method and efficient therapeutic agents. circCELSR1 is up-regulated in ovarian cancer, but its role and mechanisms in ovarian cancer are unclear.

Methods: Gene expression of circCELSR1, miR-598 and BRD4 in ovarian cells was examined by qRT-PCR.

lncRNA ABHD11-AS1, regulated by the EGFR pathway, contributes to the ovarian cancer tumorigenesis by epigenetically suppressing TIMP2.

Objective: Epithelial ovarian cancer (EOC) is a common gynecologic malignancy characterized by extensive peritoneal metastasis and high mortality rate. ABHD11 Antisense RNA1 (ABHD11-AS1) has recently been identified as a regulator of growth and metastasis in multiple tumors, including EOC. However, the biological function and potential mechanism of ABHD11-AS1 in EOC remains poorly understood.

KRAS: A Promising Therapeutic Target for Cancer Treatment.

Kirsten rat sarcoma 2 viral oncogene homolog (KRAS) is the most commonly mutated oncogene in human cancer. The developments of many cancers depend on sustained expression and signaling of KRAS, which makes KRAS a high-priority therapeutic target. Scientists have not successfully developed drugs that target KRAS, although efforts have been made last three decades.

M2-like tumor-associated macrophages-secreted EGF promotes epithelial ovarian cancer metastasis via activating EGFR-ERK signaling and suppressing lncRNA LIMT expression.

: Ovarian cancer (OC) is the gynecologic malignant tumor with high mortality. Accumulating evidence indicates that M2-like tumor-associated macrophages (TAMs) can secret EGF to participate in ovarian cancer growth, migration, and metastasis. An EGF-downregulated lncRNA, LIMT (lncRNA inhibiting metastasis), was identified as a critical regulator of mammary cell migration and invasion.

Identification of a Novel Bcl-2 Inhibitor by Ligand-Based Screening and Investigation of Its Anti-cancer Effect on Human Breast Cancer Cells.

Bcl-2 family protein is an important factor in regulating apoptosis and is associated with cancer. The anti-apoptotic proteins of Bcl-2 family, such as Bcl-2, are overexpression in numerous tumors, and contribute to cancer formation, development, and therapy resistance. Therefore, Bcl-2 is a promising target for drug development, and several Bcl-2 inhibitors are currently undergoing clinical trials.

MiR-217 Inhibits M2-Like Macrophage Polarization by Suppressing Secretion of Interleukin-6 in Ovarian Cancer.

Ovarian cancer is one of the most deadly cancers with rapid proliferation and poor prognosis among patients. Therapies focusing on regulation of tumor immunity and microenvironments are developing. MiR-217 was dysregulated in cancer progress and plays important roles in tumorigenesis and metastasis.

Tubeimoside-1, a triterpenoid saponin, induces cytoprotective autophagy in human breast cancer cells in vitro via Akt-mediated pathway.

Autophagy, a form of cellular self-digestion by lysosome, is associated with various disease processes including cancers, and modulating autophagy has shown promise in the treatment of various malignancies. A number of natural products display strong antitumor activity, yet their mechanisms of action remain unclear. To gain a better understanding of how traditional Chinese medicine agents exert antitumor effects, we screened 480 natural compounds for their effects on autophagy using a high content screening assay detecting GFP-LC3 puncta in HeLa cells.

Suppression of eEF-2K-mediated autophagy enhances the cytotoxicity of raddeanin A against human breast cancer cells in vitro.

Recent evidence shows that raddeanin A (RA), an oleanane-type triterpenoid saponin extracted from Anemone raddeana Regel, exerts remarkable cytotoxicity against cancer cells in vitro and in vivo. In addition, RA has also been found to activate autophagy in human gastric cancer cells. In this study, we investigated the molecular mechanisms underlying RA-induced autophagy as well as the relationship between RA-induced autophagy and its cytotoxicity in human breast cancer cells in vitro.

Decreased expression of interleukin-37 in the ectopic and eutopic endometria of patients with adenomyosis.

Previous studies have shown that alterations of cytokines might play a role in the pathogenesis of adenomyosis. This study aims to investigate the expression of interleukin-37 (IL-37), an anti-inflammatory cytokine, in the eutopic and ectopic endometria of patients with adenomyosis. Endometrial specimens were collected from 30 women with adenomyosis and 20 without adenomyosis.

A Combination Therapy with Baicalein and Taxol Promotes Mitochondria-Mediated Cell Apoptosis: Involving in Akt/β-Catenin Signaling Pathway.

Baicalein, a major flavonoid, possesses anticancer and anti-inflammatory activity. The aim of the study is to explore the efficiency of combination therapy with baicalein and taxol, as well as the molecular mechanism on antitumor activity. Human ovarian cancer cells were treated with different concentration of baicalein for 48 h, and cell viability was determined by MTT assay.

[Cisplatin inhibits proliferation of cervical carcinoma cell line by up-regulating Stat1 expression].

Objective: To investigate the role of Stat1 gene in the proliferation and chemotherapeutic sensitivity of cervical cancer HeLa cells.

Methods: The protein expression of Stat1 in the Hela cells exposed to gradient concentrations of cisplatin (DDP) was detected by Western blotting with or without small interfering RNA (siRNA)-mediated Stat1 gene silencing. The effect of Sata1 silencing on the sensitivity to DDP and cell proliferation of the cells was tested using MTT assay and BrdU assay, and the expression of c-Myc was detected by Western blotting in the cells treated with siRNA and DDP.

Analysis of the efficacy of three treatment options for cesarean scar pregnancy management.

Aim: To assess three different methods in treating patients with cesarean scar pregnancy (CSP).

Methods: We evaluated pre-, intra- and postoperative conditions of 124 CSP patients in one of the three treatment groups, of which 37 patients underwent uterine curettage by hysteroscopy under ultrasound monitoring (group 1), 28 patients were treated with methotrexate followed by hysteroscopy (group 2) and 59 cases underwent uterine arterial embolization followed by hysteroscopy (group 3). The treatment options were determined based on the patients' conditions.

[Synchronous primary endometrial and fallopian tube cancers: one case report].

A patient was admitted for menopause for 2 years and abnormal vaginal bleeding and abdominal pain for 2 months. Gynecological examination revealed uterine atrophy without abnormal findings in the bilateral adnexa. CA125 and CEA levels were normal.

[Peritoneal fluid leptin concentration and endocrine hormone in patients with polycystic ovarian syndrome].

Objective: To determine whether the infertile patients with polycystic ovarian syndrome (PCOS) is related to dysregulation of peritoneal fluid and serum leptin concentration, and to investigate the relationship between the leptin and some endocrine hormones in PCOS.

Methods: Twenty subjects with PCOS and 20 control women were included in the study. Peritoneal fluid and serum concentration of leptin, insulin, insulin-antibody, testosterone (T), estrogen (E(2)), and progestogen (P) were measured by radioimmunoassay (RIA).
