BACKGROUND: To limit the potential short and long-term morbidity of lymphadenectomy, sentinel lymph node (SLN) biopsy has been proposed for endometrial cancer. The principle of SLN biopsy relies on removal of a small number of lymph nodes that are the first drainage basins from a tumor and thus the most likely to harbor tumor cells. While the procedure may reduce morbidity, efficacy data is limited and little is known about how commonly the procedure is performed. OBJECTIVE: We examined the patterns and predictors of use of SLN biopsy and outcomes of the procedure in women with endometrial cancer who underwent hysterectomy...

By analyzing the expression profile of microRNAs in head and neck squamous cell carcinomas (HNSCC), we found that the expression level of miR-124 was 4.59-fold lower in tumors than in normal tissues. To understand its functions, we generated a miR-124-expressing subline (JHU-22miR124) and a mock vector-transfected subline (JHU-22vec) by transfecting the mimic of miR-124 into JHU-22 cancer cells. Restored expression of miR-124 in JHU-22miR124 cells led to reduced cell proliferation, delayed colony formation, and decreased tumor growth, indicating a tumor-suppressive effect of miR-124...

Bee Ling Tan, Mohd Esa Norhaizan
Cancer is a significant global health concern affecting men and women worldwide. Although current chemopreventive drugs could inhibit the growth of cancer cells, they exert many adverse side effects. Dietary factor plays a crucial role in the management of cancers and has drawn the attention of researchers to be used as an option to combat this disease. Both in vitro and in vivo studies showed that rice and its by-products display encouraging results in the prevention of this disease. The mechanism of anticancer effect is suggested partly through potentiation of bioactive compounds like vitamin E, phytic acid, γ-aminobutyric acid (GABA), γ-oryzanol, and phenolics...

Artesunate (ART) is a sesquiterpene lactone isolated from the leafy portions of the Chinese herb Artemisia annua. Here, we evaluated the effect of ART on the prostate cancer (PCa) cell lines DU145 and LNCaP and explored its potential mechanisms. ART inhibited the viability and mobility of DU145 and LNCaP cells. Mechanistically, we found that UCA1, one of the most important lncRNAs in malignancies of the urinary system, may be a potential mediator contributing to the tumor suppressor function of ART. First, the UCA1 level was reduced significantly after being exposed to ART...

Mesenchymal stem cells are widely used in many pre-clinical and clinical settings. Despite advances in molecular technology; the migration and homing activities of these cells in in vivo systems are not well understood. Labelling mesenchymal stem cells with gold nanoparticles has no cytotoxic effect and may offer suitable indications for stem cell tracking. Here, we report a simple protocol to label mesenchymal stem cells using 80 nm gold nanoparticles. Once the cells and particles were incubated together for 24 h, the labelled products were injected into the rat subretinal layer...

Cancer cells may acquire drug resistance by activating DNA repair signaling. Poly ADP-ribose polymerase (PARP) plays an important role in DNA repair and it is overexpressed in many cancers including chronic myeloid leukemia (CML). PARP inhibitors have been used either alone or with other drugs to augment cancer cell death. However, whether PARP inhibitors may also augment cell death induced by chemotherapeutic agents in CML cells has not been studied. K562 cells with or without PARP-1 knockdown were treated with cisplatin alone or together with olaparib...

PURPOSE: Several characteristics of lymph node metastasis (LNM) as predictors of the risk of recurrence or death were examined in patients with papillary thyroid carcinoma (PTC). The presence of cancerous nodules as a characteristic of LNMs in PTC has not yet been reported. The objective of this study was to evaluate the use of the cancerous nodules in the lymph node (CNLN) to determine the risk of distant metastasis and survival in patients with PTC. METHODS: This retrospective observational cohort study enrolled 1408 patients with pathologically confirmed PTC without initial distant metastasis who underwent thyroidectomy and neck dissection...

Curcumin has high potential in suppressing many types of cancer and overcoming multi-drug resistance in a multi-faceted manner by targeting diverse molecular targets. However, the rather low systemic bioavailability resulted from its extremely low aqueous solubility and rapid metabolism and excretion in vivo has hampered its application in cancer therapy. With the primary aim to increase the aqueous solubility of curcumin while retaining its stability in the blood circulation before it accesses the tumor site, here we report preparation of curcumin-loaded N-(tert-butoxycarbonyl)-L-phenylalanine end-capped methoxy-poly(ethylene glycol)-block-poly(ε-caprolactone) (mPEG-PCL-Phe(Boc)) micelles with high stability both in vitro and in vivo and anti-tumor efficacy...

Precursor mRNA (pre-mRNA) splicing is catalyzed by a large ribonucleoprotein complex known as the spliceosome. Numerous studies have indicated that aberrant splicing patterns or mutations in spliceosome components, including the splicing factor 3b subunit 1 (SF3B1), are associated with hallmark cancer phenotypes. This has led to the identification and development of small molecules with spliceosome-modulating activity as potential anticancer agents. Jerantinine A (JA) is a novel indole alkaloid which displays potent anti-proliferative activities against human cancer cell lines by inhibiting tubulin polymerization and inducing G2/M cell cycle arrest...

Activating mutation of epidermal growth factor receptor (EGFR) is correlated with malignant lung tumor. In this study, we demonstrated that recombinant LZ-8 (rLZ-8), a medicinal mushroom Ganoderma lucidum protein, induced cell cycle arrest and apoptosis by downregulating the expression of wild-type and mutated EGFR and inhibiting EGFR downstream effectors, AKT and ERK1/2 in lung cancer cells. We showed that rLZ-8 effectively inhibited lung cancer progression and suppressed EGFR expression of lung tumor lesions in mouse model...

Hepatocellular carcinoma is the second most common cause of cancer-related deaths worldwide. Due to a high propensity to metastasize, active angiogenesis and rapid proliferation, recurrence and poor prognosis are major obstacles for treatment and cure of this disease. However, the detailed mechanisms of how fatty acid synthase (FASN) promotes migration, invasion and healing in tumor cells remain unclear. In the present study, the previous results that FASN was expressed higher in cancer samples than in non-cancerous samples, and influenced migration, invasion of hepatoma carcinoma cells, were verified by immunohistochemistry, tissue microarrays, Transwell assay and wound healing assay...

Cancer cell lines are major model systems for mechanistic investigation and drug development. However, protein expression data linked to high-quality DNA, RNA, and drug-screening data have not been available across a large number of cancer cell lines. Using reverse-phase protein arrays, we measured expression levels of ∼230 key cancer-related proteins in >650 independent cell lines, many of which have publically available genomic, transcriptomic, and drug-screening data. Our dataset recapitulates the effects of mutated pathways on protein expression observed in patient samples, and demonstrates that proteins and particularly phosphoproteins provide information for predicting drug sensitivity that is not available from the corresponding mRNAs...

Mass spectrometry-based stable isotope labeling has become a key technology for protein and small-molecule analyses. We developed a multiplexed quantification method for simultaneous proteomics and amine metabolomics analyses via nano reversed-phase liquid chromatography-tandem mass spectrometry (nanoRPLC-MS/MS), called mass defect-based N,N-dimethyl leucine (mdDiLeu) labeling. The duplex mdDiLeu reagents were custom-synthesized with a mass difference of 20.5 mDa, arising from the subtle variation in nuclear binding energy between the two DiLeu isotopologues...

Esophageal cancer is one of the most common malignant tumors of the digestive tract. The greatest obstacle to the curing of esophageal cancer is its propensity to spread and metastasize. Esophageal cancer stem cells are considered the source for recurrence and metastasis of the tumors. While clinical evidence suggested that continuous up-regulation of CXCL12/CXCR4 was significantly associated with poor prognosis in patients with esophageal cancer, but the role and mechanism of CXCL12/CXCR4 in the invasion and metastasis of esophageal cancer has not been reported by far...
