Phytochemicals in Cancer Prevention and Therapy

Despite advances in modern medicine, cancer is still the major cause of mortality in both developing and developed countries. Search for safer and more effective chemoprevention and treatment strategy is a need for the improvement of patient care in the field. Prevention may be more effective and less costly because cancer is largely a preventable disease which could be attributed to a greater extent to lifestyle. Dietary phytochemicals have been used for the treatment of cancer throughout history due to their safety, low toxicity, and general availability. Population based studies suggest that a reduced risk of cancer is associated with high consumption of vegetables and fruits. Promising phytochemicals not only disrupt aberrant signaling pathways leading to cancer but also synergize with chemotherapy and radiotherapy. Thus, the cancer chemoprevention and therapeutic potential of naturally occurring phytochemicals are of great interest. In this special issue we have collected many interesting original research articles and reviews that provide solid evidence to support the application of phytochemicals or dietary agents in prevention and treatment of cancer

Clinical Progress of Epilepsy in Children with Tuberous Sclerosis: Prognostic Factors for Seizure Outcome

The incidence and outcome of epilepsy in tuberous sclerosis (TS) patients have not yet been thoroughly investigated. The aim of this study was to evaluate the clinical features and prognosis of epileptic seizures associated with TS. The medical records of 29 patients who satisfied the diagnostic criteria for TS and were followed up for at least 2 years at the Department of Pediatrics, Chonnam National University Hospital (CNUH), between January 2000 and December 2010 were reviewed. Onset age of seizure, initial electroencephalography (EEG) findings, and efficacy of treatment were evaluated. Brain imaging studies were reanalyzed to determine the number of cortical tubers and subependymal nodules present. A total of 26 (89.6%) cases presented with seizures. In the seizure-controlled group (n=9, 34.6%), the mean number of cortical tubers was 4.5 (range, 0-16) and the mean number of subependymal nodules was 6.2 (range, 0-14). Initial EEG identified epileptiform discharges in 4 (44.5%) of these cases. In the seizure-sustained group (n=17, 58.6%), 10 patients had initial seizures before 1 year of age. In this group, the mean number of cortical tubers was 6.0 (range, 0-20) and the mean number of subependymal nodules was 6.0 (range, 1-11). A total of 15 (88.2%) had epileptiform discharges on their initial EEGs. In three patients who did not show any seizures during the observation period, the mean number of cortical tubers was 1.3 (range, 0-2), and the mean number of subependymal nodules was 4.6 (range, 0-13). Medical intractability of epilepsy in conjunction with TS did not correlate with age at onset of seizure, the number of cortical tubers, or subependymal nodules, but was associated with initial EEG findings

A case of Bickerstaff's brainstem encephalitis in childhood

Bickerstaff&apos&#59;s brainstem encephalitis (BBE) is a rare disease diagnosed by specific clinical features such as &apos&#59;progressive, relatively symmetric external ophthalmoplegia and ataxia by 4 weeks&apos&#59; and &apos&#59;disturbance of consciousness or hyperreflexia&apos&#59; after the exclusion of other diseases involving the brain stem. Anti-ganglioside antibodies (GM, GD and GQ) in the serum or cerebrospinal fluid (CSF) are sometimes informative for the diagnosis of BBE because of the rarity of positive findings in other diagnositic methods: brain magnetic resonance imaging (MRI), routine CSF examination, motor nerve conduction study, and needle electromyography. We report a rare case of childhood BBE with elevated anti-GM1 antibodies in the serum, who had specific clinical symptoms such as a cranial polyneuropathy presenting as ophthalmoplegia, dysarthria, dysphagia, and facial weakness&#59; progressive motor weakness&#59; altered mental status&#59; and ataxia. However, the brain MRI, routine CSF examination, nerve conduction studies, electromyography, somatosensory evoked potentials, and brainstem auditory evoked potentials were normal. BBE was suspected and the patient was successfully treated with intravenous immunoglobulins

Antioncogenic and Oncogenic Properties of Nrf2 in Arsenic-Induced Carcinogenesis

Arsenic (As3+) is a carcinogen with considerable environmental and occupational relevancy. The present study shows that As3+-transformed human lung bronchial epithelial BEAS-2B cells (AsT cells) exhibit the property of apoptosis resistance. The level of basal reactive oxygen species (ROS) is very low in AsT cells in correlation with elevated expressions of both antioxidant enzymes and antiapoptotic proteins. Nuclear factor erythroid 2-related factor (Nrf2) and p62 are constitutively expressed. These two proteins up-regulate antioxidant enzymes and antiapoptotic proteins. The knockdown of Nrf2 or p62 by small interfering RNA (siRNA) enhanced both ROS levels and As3+-induced apoptosis in transformed cells. AsT cells have autophagy deficiency as evidenced by reduced formation of microtubule-associated protein 1 light chain 3 (LC3)-II, GFP-LC3 puncta, and autophagy flux. Results obtained using a soft agar assay and shRNA Nrf2-transfected cells show that Nrf2 plays an antioncogenic role before transformation, whereas this transcription factor plays an oncogenic role after transformation. In addition, depletion of Nrf2 by shRNA dramatically inhibited growth and proliferation of transformed cells. Furthermore, the Nrf2 protein levels and antiapoptotic and antioxidant enzyme levels are higher in lung adenocarcinoma than in normal tissues. Collectively, this study demonstrates that a constitutively high level of Nrf2 in AsT cells up-regulates the antioxidant proteins catalase and superoxide dismutase as well as the antiapoptotic proteins Bcl-2 and Bcl-xL. The final consequences are decreased ROS generation and increased apoptotic resistance, cell survival and proliferation, and tumorigenesis

Interleukin-2 induces the in vitro maturation of human pluripotent stem cell-derived intestinal organoids.

Human pluripotent stem cell (hPSC)-derived intestinal organoids (hIOs) form 3D structures organized into crypt and villus domains, making them an excellent in vitro model system for studying human intestinal development and disease. However, hPSC-derived hIOs still require in vivo maturation to fully recapitulate adult intestine, with the mechanism of maturation remaining elusive. Here, we show that the co-culture with human T lymphocytes induce the in vitro maturation of hIOs, and identify STAT3-activating interleukin-2 (IL-2) as the major factor inducing maturation. hIOs exposed to IL-2 closely mimic the adult intestinal epithelium and have comparable expression levels of mature intestinal markers, as well as increased intestine-specific functional activities. Even after in vivo engraftment, in vitro-matured hIOs retain their maturation status. The results of our study demonstrate that STAT3 signaling can induce the maturation of hIOs in vitro, thereby circumventing the need for animal models and in vivo maturation

Quercetin Inhibits Angiogenesis Mediated Human Prostate Tumor Growth by Targeting VEGFR- 2 Regulated AKT/mTOR/P70S6K Signaling Pathways

Angiogenesis is a crucial step in the growth and metastasis of cancers, since it enables the growing tumor to receive oxygen and nutrients. Cancer prevention using natural products has become an integral part of cancer control. We studied the antiangiogenic activity of quercetin using ex vivo, in vivo and in vitro models. Rat aortic ring assay showed that quercetin at non-toxic concentrations significantly inhibited microvessel sprouting and exhibited a significant inhibition in the proliferation, migration, invasion and tube formation of endothelial cells, which are key events in the process of angiogenesis. Most importantly, quercetin treatment inhibited ex vivo angiogenesis as revealed by chicken egg chorioallantoic membrane assay (CAM) and matrigel plug assay. Western blot analysis showed that quercetin suppressed VEGF induced phosphorylation of VEGF receptor 2 and their downstream protein kinases AKT, mTOR, and ribosomal protein S6 kinase in HUVECs. Quercetin (20 mg/kg/d) significantly reduced the volume and the weight of solid tumors in prostate xenograft mouse model, indicating that quercetin inhibited tumorigenesis by targeting angiogenesis. Furthermore, quercetin reduced the cell viability and induced apoptosis in prostate cancer cells, which were correlated with the downregulation of AKT, mTOR and P70S6K expressions. Collectively the findings in the present study suggest that quercetin inhibits tumor growth and angiogenesis by targeting VEGF-R2 regulated AKT/mTOR/P70S6K signaling pathway, and could be used as a potential drug candidate for cancer therapy

Hexavalent Chromium Induces Malignant Transformation of Human Lung Bronchial Epithelial Cells Via ROS-Dependent Activation of miR-21-PDCD4 Signaling

Hexavalent chromium [Cr(VI)] is a well-known human carcinogen associated with an increased risk of lung cancer. However, the mechanisms underlying Cr(VI)-induced carcinogenesis remain unclear. MicroRNA-21 (miR-21) is a key regulator of oncogenic processes. Studies have shown that miR-21 exerts its oncogenic activity by targeting the tumor suppressor gene programmed cell death 4 (PDCD4). The present study examined the role of miR-21-PDCD4 signaling in Cr(VI)-induced cell transformation and tumorigenesis. Results showed that Cr(VI) induces ROS generation in human bronchial epithelial (BEAS-2B) cells. Chronic exposure to Cr(VI) is able to cause malignant transformation in BEAS-2B cells. Cr(VI) caused a significant increase of miR-21 expression associated with an inhibition of PDCD4 expression. Notably, STAT3 transcriptional activation by IL-6 is crucial for the Cr(VI)-induced miR-21 elevation. Stable knockdown of miR-21 or overexpression of PDCD4 in BEAS-2B cells significantly reduced the Cr(VI)-induced cell transformation. Furthermore, the Cr(VI) induced inhibition of PDCD4 suppressed downstream E-cadherin protein expression, but promoted β-catenin/TCF-dependent transcription of uPAR and c-Myc. We also found an increased miR-21 level and decreased PDCD4 expression in xenograft tumors generated with chronic Cr(VI)-exposed BEAS-2B cells. In addition, stable knockdown of miR-21 and overexpression of PDCD4 reduced the tumorogenicity of chronic Cr(VI)-exposed BEAS-2B cells in nude mice. Taken together, these results demonstrate that the miR-21-PDCD4 signaling axis plays an important role in Cr(VI)-induced carcinogenesis
