Homologous-targeting biomimetic nanoparticles for photothermal therapy and Nrf2-siRNA amplified photodynamic therapy against oral tongue squamous cell carcinoma
Publication date: 15 May 2020Source: Chemical Engineering Journal, Volume 388Author(s): Shurui Shi, Yue Wang, Beibei Wang, Qian Chen, Guoyun Wan, Xiaoying Yang, Juan Zhang, Lianyun Zhang, Changyi Li, Yinsong WangAbstractPhotothermal therapy (PTT) and photodynamic therapy (PDT) have some advantages such as site selectivity, non- or little-invasive property and negligible drug resistance for treatment of oral tongue squamous cell carcinoma (OTSCC). However, the activation of intracellular antioxidant responses will partly counteract anticancer effects of PDT. As a well-known redox-regulated transcription factor, Nrf2 has bee...

Abstract 1428: Targeting RRM2 by siRNA inhibits cellular invasion and represents a rational approach for inhibition of metastasis of head and neck and lung cancers
Background: Ribonucleotide reductase subunit M2 (RRM2) has been frequently observed to be aberrantly overexpressed in various tumors. RRM2 is a key enzyme, and essential regulator of balanced deoxyribonucleotides (dNTPs). It is critical for DNA replication and repair, and hence cell survival. In addition to DNA synthesis, it has been reported to modulate cellular invasiveness. However, the mechanisms through which RRM2 affects the invasive phenotype have not been elucidated.Methods: We evaluated the expression of RRM2 protein in metastatic (n = 40) and non-metastatic (n = 40) head and neck squamous cell carcinoma (HNSCC) t...

Delivery of MTH1 inhibitor (TH287) and MDR1 siRNA via hyaluronic acid-based mesoporous silica nanoparticles for oral cancers treatment
Publication date: 1 January 2019Source: Colloids and Surfaces B: Biointerfaces, Volume 173Author(s): Xiao-Lei Shi, Yuan Li, Lu-Ming Zhao, Lin-Wang Su, Gang DingAbstractOral cancer accounts for 95% of all maxillofacial malignant neoplasm. Presently, surgery and radiation (with and without chemotherapy) are the major treatments for oral cancer; however it met with limited therapeutic outcome. Overcoming the multidrug resistance and finding new therapeutic agents for oral cancer treatment are some of the serious challenges. Small molecule, TH287 potently and selectively inhibits the MTH1 protein in cells and could act as a ne...

Evaluating the effect of siRNA on sox2ot expression in the Human Neuron-Committed Teratocarcinoma NT2 Cellline.
Authors: Sadeghi Z, Dodange F, Maleki P, Zarei M, Taheri M, Raheb J Abstract Non-coding RNA elongated (lncRNAs) have recently attracted as molecules that regulate gene expression of the pluripotent properties (pluripotency) of stem cells. Recently our colleagues examined the role of one of these RNAs called SOX2OT in esophageal squamous cell carcinoma, and found a concomitant increase in its expression with some regulatory genes of cell proliferation. In the present study, using the design of suitable primers from SOX2OT gene, we investigated the effect of siRNA on expression of SOX2OT. PMID: 32716352 [PubMed -...

GSE178669 Next Generation Sequencing Facilitates Quantitative Analysis of Control siRNA, RAB11A siRNA1 and RAB11A siRNA2 suppressed EBC-1 cell's Transcriptomes
This study aims to find cellular pathway changes in RAB11A suppressed in lung squamous cell carcinoma cell line EBC-1 compared to control and to evaluate downregulating genes by RAB11A suppression by siRNA. Total RNA was extracted from EBC-1 transfected with control siRNA and RAB11A specific siRNAs using the RNeasy mini kit (Qiagen, Hilden, Germany). CAGE library preparation, sequencing, mapping, and gene expression and motif discovery analysis were performed by DNAFORM (Yokohama, Japan). In brief, RNA quality was assessed by Bioanalyzer (Agilent) to ensure that RIN (RNA integrity number) is over 7.0 and A260/280 and 260/2...

siRNA Targeting Net1 Reduces the Angiogenesis and Tumor Growth of in vivo Cervical Squamous Cell Carcinoma through VEGF down-regulation
Net1, a guanine nucleotide exchange factor, is implicated in cancer cell invasion through activation of RhoA. However, there is still no report on the association between Net1 and cancer angiogenesis. The current study was designed to explore the roles of Net1 in the angiogenesis of cervical squamous cell carcinoma (CSCC) and further observe the effects of Net1 siRNA on the tumor growth. Net1 was overexpressed in CSCC samples (n=80), correlated to the cancer microvessel density (MVD, r=0.223, P=.026) and related to aggressive clinical behaviors, including depth of cervical wall invasion (P=.041), parametrial involvement (P...

GSE100589 Gene expression profiling of SAS cell line transfected with siRNA targeting CYLD
Contributors : Satoru Shinriki ; Hirofumi JonoSeries Type : Expression profiling by arrayOrganism : Homo sapiensOral squamous cell carcinoma (OSCC) has a very poor prognosis due to its highly invasive nature, and 5-year survival rate has not changed apparently for the past 30 years. Although cylindromatosis (CYLD) is thought as a potent tumor suppressor, its biological and clinical significances in OSCC are largely unknown. The aim of this study was to clarify roles of CYLD in OSCC progression. Our immunohistochemical analyses revealed that CYLD expression was significantly reduced at invasive lesions in OSCC tissues where...

Inhibition of skin squamous cell carcinoma proliferation and promote apoptosis by dual silencing of NET-1 and survivin.
Authors: Ji ZJ, Wang JL, Chen L Abstract The simultaneous silencing of multiple upregulated genes is an attractive and viable strategy to treat many incurable diseases including cancer. In the present study, skin squamous cell carcinoma (SSCC) tissue microarray was constructed and the expression of NET-1 and survivin was identified. The high expression of NET-1 and survivin gene in SSCC was confirmed as an important event for the formation and development of the cancer. A total of 100 primary SSCC patients were included in the present study. Expression of NET-1 and survivin in cancer cells was evaluated immunohist...

Non-canonical Notch Signaling Regulates Actin Remodeling in Cell Migration by Activating PI3K/AKT/Cdc42 Pathway
In conclusion, our research results indicate that DAPT activates PI3K/AKT/Cdc42 signaling by non-canonical Notch pathway, and the activated Cdc42 promotes the filopodia formation and inhibits lamellipodia assembly, resulting in reduced migration of breast cancer cells. The results imply that non-canonical Notch signaling may play a very important role in the rapid response of cells to the extracellular signals. Author Contributions LG, JD, and LL designed the study and wrote and revised the manuscript. LL and LZ performed most of the experiments and data analysis. SZ, X-YZ, P-XM, Y-DM, Y-YW, YC, S-JT, and Y-JZ assisted i...

Clusterin silencing inhibits proliferation and reduces invasion in human laryngeal squamous carcinoma cells
Background: Clusterin is, in its major form, a secreted heterodimeric disulfide-linked glycoprotein (sCLU), which plays important roles in cell survival and death. In laryngeal squamous cell carcinomas (LSCC), sCLU is up-regulated and its expression is related to the invasiveness of these tumors. The purpose of this study was to explore the inhibiting role of sCLU gene silence in the invasive ability and growth of Hep-2 human laryngeal squamous carcinoma cells (Hep-2) by transfection of short hairpin RNA expression plasmids against sCLU (sCLU-shRNA) (in vivo) or small interference RNA (sCLU-siRNA) (in vitro). Methods: sCLU...
