Evaluation of the potential of ultrasound-mediated drug delivery for the treatment of ovarian cancer through preclinical studies.

Ovarian cancer (OC) has the greatest mortality rate among gynecological cancers, with a five-year survival rate of <50%. Contemporary adjuvant chemotherapy mostly fails in the case of OCs that are refractory, metastatic, recurrent, and drug-resistant. Emerging ultrasound (US)-mediated technologies show remarkable promise in overcoming these challenges.

[Retracted] Effects of cyclooxygenase‑2 gene silencing on the biological behavior of SKOV3 ovarian cancer cells.

Following the publication of the above article, the authors have requested that it be retracted. They alerted the Editorial Office to the fact that the same data, albeit with a different view, had been selected to show the 'CON' and 'NC' experiments for the colony‑formation assays featured in Fig. 6.

PSMA conjugated combinatorial liposomal formulation encapsulating genistein and plumbagin to induce apoptosis in prostate cancer cells.

Although the biomedical sciences have achieved tremendous success in developing novel approaches to managing prostate cancer, this disease remains one of the major health concerns among men worldwide. Liposomal formulations of single drugs have shown promising results in cancer treatment; however, the use of multi drugs has shown a better therapeutic index than individual drugs. The identification of cancer-specific receptors has added value to design targeted drug delivering nanocarriers.

A novel GPCR target in correlation with androgen deprivation therapy for prostate cancer drug discovery.

Most prostate carcinomas require androgen stimulation to grow, and for nearly 70 years, androgen ablation therapy has been one of the central therapeutic strategies against advanced prostate cancer. Although most tumours initially respond to this therapy, some will be acquired resistant and progress to metastatic castration-resistant (mCRPC) disease which clinically tends to progress more rapidly than earlier disease manifestations. The underlying molecular biology of mCRPC is highly complex, and numerous mechanisms have been proposed that promote and retain androgen independence.

Impaired Th17 cell proliferation and decreased pro-inflammatory cytokine production in CXCR3/CXCR4 double-deficient mice of vulvovaginal candidiasis.

Vulvovaginal candidiasis (VVC) is a common observed infection, affecting approximately 75% of women of reproductive age. Drug resistance represents a troublesome stumbling block associated with VVC therapy. Thus the aim of the present study was to provide information regarding the selection of potential drug targets for VVC.

Prostate cancer: updates on current strategies for screening, diagnosis and clinical implications of treatment modalities.

Prostate cancer is the most common cancer in men by way of diagnosis and a leading cause of cancer-related deaths. Early detection and intervention remains key to its optimum clinical management. This review provides the most updated information on the recent methods of prostate cancer screening, imaging and treatment modalities.

Phosphorylation of STAT3 at Tyr705 regulates MMP-9 production in epithelial ovarian cancer.

Ovarian cancer's poor progression is closely associated with overexpression of matrix metalloproteinase 9 (MMP-9), which belongs to the class of enzymes believed to be involved in the degradation of extracellular matrix. However, the mechanisms underlying regulation of MMP-9 are not completely understood. STAT (signal transducer and activator of transcription) family of transcription factors is well known to be engaged in diverse cellular functions.

Effects of cyclooxygenase-2 gene silencing on the biological behavior of SKOV3 ovarian cancer cells.

The aim of the present study was to investigate the effects of plasmid-mediated RNA interference targeting of cyclooxygenase-2 (COX-2) on the biological behaviors of SKOV3 human ovarian cancer cells and to analyze the function of COX-2 in carcinogenesis and development of ovarian cancer. A COX-2 small hairpin (sh)RNA sequence was designed and synthesized and pGPU6-COX-2-shRNA plasmids were constructed. The recombinant vector plasmids were stably transfected into SKOV3 cells.

A novel killer toxin produced by the marine-derived yeast Wickerhamomyces anomalus YF07b.

In our previous study, it was found that the killer toxin produced by the marine-derived yeast Wickerhamomyces anomalus YF07b has both killing activity and β-1,3-glucanase activity and the molecular mass of it is 47.0 kDa. In this study, the same yeast strain was found to produce another killer toxin which only had killing activity against some yeast strains, but had no β-1,3-glucanase activity and the molecular mass of the purified killer toxin was 67.

[Expression of ERK1/2 MAPK signaling transduction pathway in esophageal cancers in Kazakh patients].

Objective: To investigate the expression variation and significance of ERK1/2 MAPK signaling transduction pathway in the pathogenesis of esophageal squamous cell carcinoma (ESCC) in Kazakh patients.

Methods: The expression level of p-ERK1/2 after serum starvation and treatment with U0126 inhibitor was detected in esophageal cancer cell line EC9706 by Western blot assay. The mRNA level of total ERK1/2 (t-ERK1/2) and expression level of t-ERK1/2 and p-ERK1/2 proteins of 25 pairs of ESCC and adjacent normal esophageal mucosal tissues of Kazakh patients were examined and identified by real-time quantitative PCR (qRT-PCR) and Western blotting, respectively.

Clinicopathological pattern and Annexin A2 and Cdc42 status in patients presenting with differentiation and lymphnode metastasis of esophageal squamous cell carcinomas.

Annexin A2 and Cdc42 were identified by 2-dimensional electrophoresis (2-DE) and MALDI-TOF-MS between esophageal squamous cell carcinomas (ESCC) and corresponding normal esophagus mucosa in our previous study. To assess clinico-pathological pattern and Annexin A2 and Cdc42 status with respect to cell differentiation and lymphnode metastasis in patients with ESCC. The expression of Annexin A2 and Cdc42 in 22 pairs of fresh ESCC and matched tissues were detected by qRT-PCR and western blot, respectively.

Analysis of XPD genetic polymorphisms of esophageal squamous cell carcinoma in a population of Yili Prefecture, in Xinjiang, China.

To evaluate the association with genetic polymorphisms in Xeroderma pigmentosum complementation group D (XPD) gene of esophageal squamous cell carcinoma (ESCC) risk in a population of Yili Prefecture, in Xinjiang, China. A hospital-based case-control study was designed with 571 samples including 213 ESCC patients and 358 controls with age, gender and ethnicity-matched subjects (Kazakh, Uygur and Han ethnic). Genotypes were determined by PCR restriction fragment length polymorphism (PCR-RLFP) and confirmed by sequence.

Direct conversion of inulin and extract of tubers of Jerusalem artichoke into single cell oil by co-cultures of Rhodotorula mucilaginosa TJY15a and immobilized inulinase-producing yeast cells.

In this study, it was found that the immobilized inulinase-producing cells of Pichia guilliermondii M-30 could produce 169.3 U/ml of inulinase activity while the free cells of the same yeast strain only produced 124.3 U/ml of inulinase activity within 48 h.

Proteomic identification of differentially-expressed proteins in esophageal cancer in three ethnic groups in Xinjiang.

The Objective is to identify candidate biomarkers for Squamous cell carcinoma (ESCC) in three ethnics in Xinjiang as well as reveal molecular mechanism. Proteins from 15 pairs of ESCC and matching adjacent normal esophageal tissues (five pairs in each ethnic of Kazakh, Uygur and Han) were separated by 2-DE and differentially proteins were identified by matrix-assisted laser desorption/ionization time-of-flight MS. After identified by Mascot database, some of interesting proteins were confirmed in the other 175 pairs of ESCC by immuno histochemistry.
