A novel strategy of EGFR‑TKI combined chemotherapy in the treatment of human lung cancer with EGFR‑sensitive mutation. Oncol Rep. 2018 Jun 18;: Authors: Zhang L, Qi Y, Xing K, Qian S, Zhang P, Wu X Abstract The discovery of epidermal growth factor receptor (EGFR)‑sensitive mutations in non‑small cell lung cancer (NSCLC) and the successful clinical application of EGFR tyrosine kinase inhibitors (TKIs) have changed the regimen of lung cancer therapy from traditional cytotoxic chemotherapy to molecular‑targeted cancer therapy. However, the main limitation of EGFR‑TKI therapy is the hetero...

Authors: Tamura H, Higa A, Hoshi H, Hiyama G, Takahashi N, Ryufuku M, Morisawa G, Yanagisawa Y, Ito E, Imai JI, Dobashi Y, Katahira K, Soeda S, Watanabe T, Fujimori K, Watanabe S, Takagi M Abstract Patient-derived tumor xenograft models represent a promising preclinical cancer model that better replicates disease, compared with traditional cell culture; however, their use is low-throughput and costly. To overcome this limitation, patient-derived tumor organoids (PDOs) were established from human lung, ovarian and uterine tumor tissues, among others, to accurately and efficiently recapitulate the tissue architecture...

This study is aimed to investigate the association between EPHA3 expression and androgen receptor (AR) signaling and the potential mechanism. We determined mRNA and protein levels of EPHA3 and AR signaling‑related genes in the PCa cell line 22Rv1 by reverse transcription‑polymerase chain reaction (RT‑PCR) and western blotting, respectively. The EPHA3 mRNA and protein levels were both found to be elevated by dihydrotestosterone (DHT) hormone in a dose‑ and time‑dependent manner, as AR and prostate‑specific antigen (PSA) expression were increased. Similarly, EPHA3 protein levels were also increased in the PCa cel...

SB225002 inhibits prostate cancer invasion and attenuates the expression of BSP, OPN and MMP‑2. Oncol Rep. 2018 Jun 18;: Authors: Xu M, Jaing H, Wang H, Liu J, Liu B, Guo Z Abstract The mechanisms of malignant cell metastasis to secondary sites are complex and multifactorial. Studies have demonstrated that small integrin‑binding ligand N‑linked glycoproteins (SIBLINGs), particularly bone sialoprotein (BSP) and osteopontin (OPN), are involved in neoplastic growth and metastasis. SIBLINGs promote malignant cell invasion and metastasis by enhancing matrix metalloproteinase 2 (MMP‑2) and MMP‑9 ex...

Authors: Wang Y, Lin X, Fu X, Yan W, Lin F, Kuang P, Luo Y, Lin E, Hong X, Wu G Abstract Thyroid cancer is one of the most common malignant tumors of the endocrine system. Among all thyroid cancers, papillary thyroid carcinoma (PTC) is the most common type. The BRAF-activated non-coding RNA (BANCR) is a 693-bp nucleotide transcript which was first identified in melanoma. However, the role of BANCR in the development of thyroid cancer remains unclear. Therefore, the present study investigated the potential involvement of BANCR in the development of thyroid cancer in vitro using patient tissue samples and a pane...

Authors: Sun Y, Jiang F, Pan Y, Chen X, Chen J, Wang Y, Zheng X, Zhang J Abstract X‑box‑binding protein 1 (XBP1) contributes to various types of cancer including breast, bladder cancer and esophageal squamous cell carcinoma. The aim of the study was to examine the metastatic role of XBP1 in oral squamous cell carcinoma (OSCC), and identify possible downstream molecules. Immunohistochemical staining was conducted on tissue microarrays comprising 96 OSCC cases to determine the expression level of XBP1 and analyze its association with metastasis, clinicopathological characteristics and survival prognosis. Compared...

HBsAg/β2GPI activates the NF‑κB pathway via the TLR4/MyD88/IκBα axis in hepatocellular carcinoma. Oncol Rep. 2018 Jun 19;: Authors: Jing X, Tian Z, Gao P, Xiao H, Qi X, Yu Y, Ding X, Yang L, Zong L Abstract Chronic hepatitis B virus (HBV) infection remains one of the leading causes of hepatocellular carcinoma (HCC) globally. However, the mechanism underlying the mediation by HBV surface proteins (HBsAgs) of the early steps in the virus life cycle and following HCC development is unclear. β‑2‑glycoprotein I (β2GPI) specifically interacts with HBsAg and de...

Aberrantly expressed genes and miRNAs in human hypopharyngeal squamous cell carcinoma based on RNA‑sequencing analysis. Oncol Rep. 2018 Jun 19;: Authors: Li H, Wang F, Fei Y, Lei Y, Lu F, Guo P, Li W, Xun X Abstract The aim of the present study was to investigate the key genes, miRNAs and pathways in hypopharyngeal squamous cell carcinoma (HPSCC) and to elucidate the mechanisms underlying HPSCC development. The gene and microRNA (miRNA) expression profiles of HPSCC tissues and adjacent normal tissues from three subjects were obtained. Differentially expressed genes (DEGs) and differentially expressed...

Authors: Zhang XH, Yang L, Liu XJ, Zhan Y, Pan YX, Wang XZ, Luo JM Abstract Suppressor of cytokine signaling‑1 (SOCS1) is a widely recognized tumor suppressor gene. Silencing of SOCS1 expression as a result of promoter methylation is associated with occurrence and development of solid tumors such as liver, cervical and pancreatic cancer. However, the association between SOCS1 gene methylation and acute myeloid leukemia (AML) has not been well explored. In the present study, we examined whether gene expression and methylation status of SOCS1 was altered in AML, and whether this was related to disease occurrence an...
