Lung cancer cells express several cytokeratins (CKs) that are subdivided into type I (CK9-23) and type II (CK1-8) subclasses. The functions of CKs in lung cancer cells have not been fully elucidated. The purpose of this study was to investigate the role of CKs in the invasion of lung cancer cells. We investigated the expression levels of CK7, 8, 18 and 19 in 12 non-small cell lung cancer (NSCLC...
Acquired resistance to cisplatin-based chemotherapy frequently occurs in patients with non-small cell lung cancer, and the underlying molecular mechanisms are not well understood. The aim of this study was to investigate whether a distinct gene expression pattern is associated with acquired resistance to cisplatin in human lung adenocarcinoma. Whole-transcriptome sequencing was performed to com...
Macrophages in a tumor microenvironment have been characterized as M1- and M2-polarized subtypes. Here, we discovered the different macrophages' impacts on lung cancer cell A549. The M2a/M2c subtypes promoted A549 invasion and xenograft tumor growth. The M1 subtype suppressed angiogenesis. M1 enhanced the sensitivity of A549 to cisplatin and decreased the tube formation activity and cell viabil...
Hypoxia-inducible factor-2 alpha (HIF-2α) has been shown to regulate cell stemness, although the expression and effects of HIF-2α in lung cancer stem cells remained unclear. This study investigated HIF-2α expression in lung cancer stem cells, as well as the relationship between HIF-2α expression and radioresistance in lung cancer cells. Stem-like cells (CD133(+)) in the non-small-cell lung canc...
To explore the reversal effect of Fuzheng oral liquid on anlotinib resistance in non-small cell lung cancer cells and its mechanism is objective study. 3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide assay flow cytometric were performed to evaluate effects proliferation apoptotic cycles adenocarcinomic human alveolar basal epithelial line A549 cells, respectively. Western blot was...
MicroRNAs (miRNAs) are short, non‑coding RNAs that are aberrantly expressed in tumors. miRNA‑33a (miR‑33a) is closely associated with cholesterol metabolism and is essential for cellular growth. The aim of the present study was to explore the role of miR‑33a and identify its clinical significance in lung cancer cells. miR‑33a was observed to be overexpressed in the lung cancer cell lines A549 a...
Lung adenocarcinoma, which is the most common non-small cell lung cancer, is the leading cause of death from cancer worldwide. Epithelial cell transforming sequence 2 (ECT2) is frequently upregulated and acts as an oncogene in various human cancers. In addition, ECT2 was reported to be upregulated in early stage lung adenocarcinoma. However, the detailed role of ECT2 in mediating the malignant ...
Vascular cell adhesion molecule-1 (VCAM-1) is closely associated with tumor progression and metastasis. However, the relevance and role of VCAM-1 in lung cancer have not been clearly elucidated. In this study, we found that VCAM-1 was highly overexpressed in lung cancer tissue compared with that of normal lung, and high VCAM-1 expression correlated with poor survival of lung cancer patients. VC...
Vascular cell adhesion molecule-1 (VCAM-1) is closely associated with tumor progression and metastasis. However, the relevance and role of VCAM-1 in lung cancer have not been clearly elucidated. In this study, we found that VCAM-1 was highly overexpressed in lung cancer tissue compared with that of normal lung tissue, and high VCAM-1 expression correlated with poor survival in lung cancer patie...
The secreted frizzled-related protein 2 (SFRP2) plays a pivotal role in the Wnt pathway, however, it functions as an agonist or an antagonist is still controversial. We profiled SFRP2 expression in several lung cancer cell lines, and found that A549 and 95-D exhibited the lowest and the highest level of SFRP2, respectively. Then we employed the SFRP2-overexpressing plasmid and siRNA to transfec...
