Raphanus sativus L. seed extracts induce apoptosis and reduce migration of oral squamous cell carcinoma KB and KBCD133+cells by downregulation of β-catenin. Nutr Cancer. 2019 Nov 25;:1-12 Authors: Ahn K, Ji H, Kim HE, Cho H, Sun Q, Shi S, He Y, Kim BG, Kim O Abstract Although, oral cancer therapies have been developed for decades, patient survival rates have not changed. Side effects of chemotherapy and radiotherapy reduce quality of life of patients and it remains difficult to treat oral cancers due to the presence of cancer stem cells (CSCs) that cause recurrence and metastasis. Therefore, we search for natural products that affect oral cancer cells including oral cancer stem cells. In the present study, we investigated the anticancer effects of Raphanus sativus L. seed (RSLS) extracts on oral squamous cell carcinoma KB cells and CSC-like KBCD133+ cells. CD133 plays an important role in CSCs and physically binds to β-catenin to activate the β-catenin signaling targets. Therefore, a natural extract that can inhibit β-catenin act in may be effective anticancer drug acquiring CSC. Of the natural product extract candidates, RSLS extracts induced apoptosis in KB and KBCD133+ cells and inhibited nuclear translocation of β-catenin cell migration and invasion rates. Treatment of RSLS extracts resulted in increases of Axin and it leds to reductions of β-catenin in KB and KBCD133+ cells. Hence, the result suggests that RSLS are pote...

This study examined the effects of ouabain stimulation on spontaneous interleukin (IL)-8 and IL-1α secretion in the HSC3 oral squamous cell carcinoma cell line. IL-8 secretion was reduced and IL-1α secretion was increased in the cells. Real-time polymerase chain reaction confirmed that these changes were regulated at the transcriptional level. Further analysis revealed that ouabain stimulation induced phosphorylation of activator protein (AP)-1 components (c-Jun and c-Fos) but not nuclear factor kappa B (NF-κB) components (p65 and p50). A luciferase assay demonstrated that the NF-κB-binding site loc...

Ott Research Institute of Obstetrics, Gynecology and Reproductology, Saint Petersburg, Russia 2Department of Genetics and Biotechnology, Saint Petersburg State University, Saint Petersburg, Russia In the present review, we focus on the phenomenon of chromothripsis, a new type of complex chromosomal rearrangements. We discuss the challenges of chromothripsis detection and its distinction from other chromoanagenesis events. Along with already known causes and mechanisms, we introdu...

Conclusion Most head and neck pathologies show a broad cellular heterogeneity making it difficult to achieve an accurate diagnosis and efficient treatment (Graf and Zavodszky, 2017; Lo Nigro et al., 2017). Single cell analysis of circadian omics (Lande-Diner et al., 2015; Abraham et al., 2018), may be a crucial tool needed in the future to fully understand the circadian control of head and neck diseases. It becomes more obvious that there is only a small genetic component but a largely unknown epigenetics and/or environmental component for most of the head and neck pathologies (Moosavi and Motevalizadeh Ardekani, 2016; He...

In this study, we unveiled that LEF1-AS1 markedly increased in oral squamous cell carcinoma (OSCC) tissues and cell lines. Besides, OSCC patients with high levels of LEF1-AS1 were apt to poor prognosis. Functionally, LEF1-AS1 knockdown inhibited cell survival, proliferation and migration, whereas enhanced cell apoptosis and induced G0/G1 cell cycle arrest in vitro. Consistently, LEF1-AS1 silence hindered tumor growth in vivo. Moreover, LEF1-AS1 inhibition stimulated the activation of Hippo signaling pathway through directly interacting with LATS1. Furtherly, we disclosed that LEF1-AS1 silence abolished the interaction of L...

This report supports that the novel mutation of RNF139 p.Q650R probably serve as a key role in HBs progression. Introduction Central nervous system hemangioblastomas (HBs) are benign tumors which usually occur in cerebellum (1), and the pathogenesis of HBs is still unknown. According to the revised World Health Organization (WHO) classification of tumors of the nervous system published in 2000, HBs were classified to the tumors of uncertain histogenesis. The morphology code of the International Classification of Diseases for Oncology (ICD-O)is 9161/1, grade I. HBs are composed of mesenchymal cells and abundant capi...

Yi He†, Wenyong Long† and Qing Liu* Department of Neurosurgery, Xiangya Hospital, Central South University, Changsha, China Super-enhancers (SEs) refer to large clusters of enhancers that drive gene expressions. Recent data has provided novel insights in elucidating the roles of SEs in many diseases, including cancer. Many mechanisms involved in tumorigenesis and progression, ranging from internal gene mutation and rearrangement to external damage and inducement, have been demonstrated to be highly associated with SEs. Moreover, translocation, formation, deletion, or duplication of SEs themselves co...

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

In conclusion, the high structural diversity of these compounds pinpoints the significant range of inhibition strategies that can be conceived to target the class I methyltransferases. Although the structural details of the various members of this family are unique, the success stories of drug design for several enzymes belonging to this family portends the likely achievement of discovering potent and selective inhibitors of METTL3/METTL14.

Translocation associated membrane protein 2 (TRAM2) has been characterized as a component of the translocon that is a gated channel at the endoplasmic reticulum (ER) membrane. TRAM2 is expressed in a wide variety of human organs. To date, no information is available regarding TRAM2 function in the genesis of human cancer. The purpose of this study was to investigate the status of the TRAM2 gene in oral squamous cell carcinoma (OSCC) cells and clinical OSCC samples. Using real-time quantitative reverse transcriptase-polymerase chain reaction, Western blotting analysis, and immunohistochemistry, we detected accelerated TRAM2...
