Preventative effect of celecoxib in dimethylbenzaanthracene-induced ovarian cancer in rats.

The present study investigated the preventive effect of the cyclooxygenase (COX)-2 inhibitor, celecoxib, in 7,12-dimethylbenz[a]anthracene (DMBA)-induced ovarian cancer in a rat model.

Fibrosis of mesothelial cell-induced peritoneal implantation of ovarian cancer cells.

Peritoneal metastasis frequently occurs in patients with advanced ovarian cancer and is the main basis for a poor prognosis. The mechanism underlying preferential ovarian cancer spread to the peritoneum is not well understood.

Upregulation of cystathionine-γ-lyase/hydrogen sulfide pathway underlies the celecoxib counteraction of cyclosporine-induced hypertension and renal insult in rats.

We recently reported that celecoxib, a selective cyclooxygenase-2 (COX2) inhibitor, counteracts the adverse circulatory and renal actions of cyclosporine (CSA). Despite the seemingly advantageous nature of this interaction particularly in clinical settings that necessitate the combined use of the two drugs such as immune-related arthritis, the underlying mechanism remains elusive. This prompted us to test the hypothesis that the facilitation of the cystathionine-γ-lyase (CSE)/hydrogen sulfide (HS) signalin...

DHA but not AA Enhances Cisplatin Cytotoxicity in Ovarian Cancer Cells.

Clinical and epidemiological studies show that docosahexaenoic acid (DHA) and arachidonic acid (AA) exert multiple effects on ovarian cancer. While DHA seems to inhibit growth and prevent carcinogenic processes, stimulation of leukotriene B4 receptors BLT1 and BLT2 by several eicosanoids derived from AA plays an important role in mediating cisplatin resistance in ovarian cancer cells. We examined whether DHA and AA exerted antiproliferative effect on epithelial ovarian cancer cells and whether these polyuns...

Ginsenoside 20(S)-Rg3 Prevents PKM2-Targeting miR-324-5p from H19 Sponging to Antagonize the Warburg Effect in Ovarian Cancer Cells.

The Warburg effect is one of the main metabolic features for cancers, with long non-coding RNA (lncRNA) being involved as a class of crucial regulators. Our previous studies have shown that ginsenoside 20(S)-Rg3, an active saponin monomer extracted from red ginseng, inhibits the Warburg effect in ovarian cancer cells. However, the detailed lncRNA regulatory network modulated by 20(S)-Rg3 to prevent the Warburg effect in ovarian cancer cells has not been explored.

Thyroid Cancer Benefits the Prognosis of Ovarian Cancer: A SEER-Based Study.

To explore the effect of a second thyroid cancer (TC) on ovarian cancer (OC) patient survival, we compared OC patients with or without a second primary TC using data from the Surveillance, Epidemiology, and End Results (SEER) database.

KDM6B promotes ovarian cancer cell migration and invasion by induced transforming growth factor-β1 expression.

KDM6B, also known as JMJD3, is a member of the family of histone lysine demethylase (KDMs), which is closely related to many types of cancers. However, its role and the underlying mechanisms in ovarian cancer remain unknown. Here we show that KDM6B is elevated in epithelial ovarian cancer and its expression level is closely related with metastasis and invasion. In addition, survival analysis showed that high expression of KDM6B was associated with low overall survival in ovarian cancer patients. Overexpress...

Enhanced expression of COX-2 and Glut-1 proteins are reported as major factors leading to the origin and progress of prostate cancer through modulating the associated signaling pathways. In this study, we have synthesized a multifunctional liposomal system containing celecoxib and genistein drugs. The comb...

Identification of molecular marker associated with ovarian cancer prognosis using bioinformatics analysis and experiments.

Ovarian cancer is one of the three major malignant tumors of the female reproductive system, and the mortality associated with ovarian cancer ranks first among gynecologic malignant tumors. The pathogenesis of ovarian cancer is not yet clearly defined but elucidating this process would be of great significance for clinical diagnosis, prevention, and treatment. For this study, we used bioinformatics to identify the key pathogenic genes and reveal the potential molecular mechanisms of ovarian cancer; we used ...

LncRNAs in ovarian cancer.

Ovarian cancer is one of the most common gynecologic malignancies and has a poor prognosis. Recently, long noncoding RNAs (lncRNAs) have been identified as key regulators of cancer development. Studies have shown that the dysregulation of lncRNAs is frequently observed in ovarian cancer and greatly contributes to malignant phenotypical changes. In this review, we provide perspectives on the involvement of lncRNAs in the proliferation, apoptosis, cell cycle, migration, invasion, metastasis and drug resistanc...

Association of metformin use with ovarian cancer incidence and prognosis: a systematic review and meta-analysis.

Some clinical and basic research studies have indicated that exposure to metformin might have protective effects against ovarian cancer. However, results from epidemiologic studies have been inconsistent. We performed a meta-analysis to evaluate the effect of metformin use on the risk of ovarian cancer occurrence and mortality.

miR-603 targeted hexokinase-2 to inhibit the malignancy of ovarian cancer cells.

The Warburg effect, characterized by energy production through a high rate of aerobic glycolysis, is a metabolic hallmark of cancer cells. We previously found that ginsenoside 20(S)-Rg3 upregulated miR-603 and impaired the malignancy of ovarian cancer cells by inhibiting the Warburg effect. However, the precise functional role of miR-603 in ovarian cancer progression remains poorly defined. Here, we report that the level of miR-603 in ovarian cancer tissues is significantly lower than that in para-tumor tis...

Encapsulation of verapamil and doxorubicin by MPEG-PLA to reverse drug resistance in ovarian cancer.

Ovarian cancer is usually treated with transurethral resection or systemic chemotherapy in clinic. However, the development of drug resistance in ovarian cancer is frequently observed in ovarian cancer patients, leading to failure of tumor inhibition and recurrence. In this study, we aimed to efficiently reverse the drug resistance and enhance the anticancer effects by co-delivery of chemotherapeutic agents and multi-drugs resistant proteins inhibitor in ovarian cancer treatment.

Neural mechanisms involved in the noxious physical stress-induced inhibition of ovarian estradiol secretion.

Stress is known to change the secretion of ovarian steroid hormones via the hypothalamic-pituitary-ovarian (HPO) axis. Noxious physical stress can cause reflex responses in visceral function via autonomic nerves. This article reviews our recent animal studies on neural mechanisms involved in ovarian estradiol secretion induced by noxious physical stress stimulation. In anesthetized rats, noxious physical stress (pinching the hindpaw or electrical stimulation of the tibial nerve) decreased ovarian estradiol ...

The antitumor effects of entinostat in ovarian cancer require adaptive immunity.

Ovarian cancer is poorly immunogenic; however, increased major histocompatibility complex class II (MHCII) expression correlates with improved immune response and prolonged survival in patients with ovarian cancer. The authors previously demonstrated that the histone deacetylase inhibitor entinostat increases MHCII expression on ovarian cancer cells. In the current study, they evaluated whether entinostat treatment and resultant MHCII expression would enhance beneficial immune responses and impair tumor gro...

Ovarian cancer is a common pathology in the structure of tumors among elderly women. The aim of the work is to identify the leading indicators of interleukin profile to improve the diagnosis of ovarian cancer in the elderly. Enzyme immunoassay studied serum levels of interleukins in 78 patients with ovarian cancer stage IIB-IIIB according to the classification of FIGO at the age of 65-70 years and 42 women of similar age without ovarian cancer at the time of the study and in history. The differentiation of ...

Osteoprotective Effects of Tribulus terrestris L.: Relationship Between Dehydroepiandrosterone Levels and Ca-Sparing Effect.

Osteoporosis is a systemic bone disease that is characterized by impairments in bone strength that predispose an individual to a higher risk of fractures. Despite the various etiologies, undoubtedly the most important factors are aging of the population and hypogonadism. Although several therapeutic options are available, pharmacological treatments have some risks. Among these are increases in the incidence of thrombosis, breast cancer, ovarian cancer, endometrial cancer, and muscle injury, among others. He...

Nanocrystalline solid dispersions (NSD) of hesperetin (HRN) for prevention of 7, 12-dimethylbenzaanthracene (DMBA)-induced breast cancer in Sprague-Dawley (SD) rats.

Breast cancer is the most commonly diagnosed cancer and the leading cause of cancer death in females as per the global cancer project (GLOBOCAN 2018) estimates of breast cancer incidence and mortality produced by the International Agency for Research on Cancer (IARC). In 2018, there will be 2,088,849 new cases of breast cancer and 626,679 cases of deaths due to breast cancer in 5 regions (Americas, Africa, Europe, Asia and Oceania) at 20 sites of the world. Epidemiologic studies on diet and cancer have guid...

Up-regulation of miR-383-5p suppresses proliferation and enhances chemosensitivity in ovarian cancer cells by targeting TRIM27.

MicroRNAs are small non-coding RNAs which play important roles in tumor progression. MiR-383-5p has been characterized as a cancer suppressor in several cancers. The aim of theses present study was to explore the role of miR-383-5p in the proliferation and chemosensitivity of ovarian cancer cells. MiR-383-5p expression was down-regulated while the expression of TRIM27 was up-regulated in ovarian cancer tissues and cell lines. We came up with the hypothesis that miR-383-5p might be involved in the tumor prog...

Dihydroartemisinin induces apoptosis and inhibits proliferation, migration, and invasion in epithelial ovarian cancer via inhibition of the hedgehog signaling pathway.

Dihydroartemisinin (DHA), the primary of artemisinin extracted from the traditional Chinese medicine Artemisia annua, has been used in malaria treatment for a long time. Recently, many studies have indicated that, in addition to antimalarial effects, DHA also exhibits anticancer activity in certain types of neoplasms, including ovarian cancer. However, the precise anti-ovarian cancer mechanism of DHA is still unclear. Abnormal activation of the hedgehog (Hh) pathway is closely related to tumorigenesis and p...

Integrated microarray meta-analysis identifies miRNA-27a as an oncogene in ovarian cancer by inhibiting FOXO1.

Survival of ovarian cancer patients is generally poor, partly because most of them are already at an advanced stage when diagnosed. The purpose of this study was to screen prognostic miRNAs for ovarian cancer, and to explore the underlying mechanisms.

Development and validation of an immune gene-set based Prognostic signature in ovarian cancer.

Ovarian cancer (OV) is the most lethal gynecological cancer in women. We aim to develop a generalized, individualized immune prognostic signature that can stratify and predict overall survival for ovarian cancer.

Engrailed-2 (EN2) - a novel biomarker in epithelial ovarian cancer.

Epithelial ovarian cancer is a common malignancy, with no clinically approved diagnostic biomarker. Engrailed-2 (EN2) is a homeodomain-containing transcription factor, essential during embryological neural development, which is dysregulated in several cancer types. We evaluated the expression of EN2 in Epithelial ovarian cancer, and reviewed its role as a biomarker.
