Epithelial-mesenchymal transition leads to NK cell-mediated metastasis-specific immunosurveillance in lung cancer.

Epithelial-mesenchymal transition leads to NK cell-mediated metastasis-specific immunosurveillance in lung cancer. J Clin Invest. 2018 Jan 11;: Authors: Chockley PJ, Chen J, Chen G, Beer DG, Standiford TJ, Keshamouni VG Abstract During epithelial-mesenchymal transition (EMT) epithelial cancer cells trans-differentiate into highly-motile, invasive, mesenchymal-like cells giving rise to disseminating tumor cells. Only few of these disseminated cells successfully metastasize. Immune cells and inflammation in the tumor microenvironment was shown to drive EMT, but few studies investigated the consequences of EMT on tumor immunosurveillance. In addition to initiating metastasis, we demonstrate that EMT confers increased susceptibility to NK cells and contributes, in part, to the inefficiency of the metastatic process. Depletion of NK cells allowed spontaneous metastasis without effecting primary tumor growth. EMT-induced modulation of E-cadherin and cell adhesion molecule 1 (CADM1) mediated increased susceptibility to NK cytotoxicity. Higher CADM1 expression correlates with improved patient survival in two lung and one breast adenocarcinoma patient cohorts and decreased metastasis. Our observation reveal a novel NK-mediated, metastasis-specific, immunosurveillance in lung cancer and presents a window of opportunity for the prevention of metastasis by boosting NK cell activity.

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...

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...

Placenta-specific protein 1 (PLAC1) is a cancer-related protein, which is activated and upregulated in a variety of malignant tissues, including prostate cancer, gastric adenocarcinoma, colorectal, epithelial ovarian and breast cancer. However, its biological role and clinical significance in non-small ...

This study describes our efforts to further the field of noninvasive diagnostics, specifically in the area of liquid biopsies in oncology. We employed laser scanning cytometry using highly selective antibodies to interrogate circulating tumor cells (CTCs) that were isolated using ApoStream(®) technology to identify folate receptor alpha (FRα)-positive cells. We demonstrate that FRα(+) CTCs can be isolated from patients with metastatic cancers, including NSCLC adenocarcinoma, breast cancer, and ovarian cancer, whereas squamous cell lung cancer and normal healthy controls were devoid of FRα(+) CTCs. We ...
