The aim was to investigate MAGE-A4 and MAGE-A1 protein expression in high-grade endometrial cancer and determine its correlation with histologic subtype, FIGO stage, presence of vascular invasion, disease free, and overall survival. Immunohistochemical staining was performed by using 77B (MAGE-A1) and 57B (MAGE-A4) monoclonal antibodies on paraffin-embedded sections from high-grade endometrial cancers diagnosed in University Hospital Split between 1998 and 2011 (n=77). Median follow-up time for survivors was 48 mo...

Extravascular migratory metastasis (EVMM), also known as pericytic mimicry or angiotropism, is a mechanism of angiocentric tumor spread that has been investigated mainly in cutaneous malignant melanoma where it has been associated with an increased risk of metastasis. In EVMM, the tumor cells spread along the external (ablumenal) aspect of vessels without breaching the endothelium, a process that is therefore distinct from the more widely recognized intraluminal invasion. Although EVMM has also been reported in a limited range of other tumor types, to our knowledge it has not been described in squamous cell carcinoma (SCC)...

Transforming growth factor (TGF)-β inhibited membrane associated protein, TIMAP, is the member of the myosin phosphatase targeting protein (MYPT) family of protein phosphatase 1 (PP1) regulatory subunits. The N-terminal part of TIMAP has a typical MYPT family structure with a sequence element called MyPhone (myosin phosphatase N-terminal element), a putative bipartite nuclear localization signal, a PP1 catalytic subunit binding motif, and five ankyrin repeats. The C-terminal half of TIMAP is intrinsically disordered, but ends with a functional CAAX box for lipid modification which allows localization of TIMAP at the plasma membrane...

In addition to being crucial for host immune defense, vitamin D is involved in cell proliferation, apoptosis, differentiation, inflammation, invasion and metastasis, angiogenesis and micro-RNA modulation. To date, clinical studies have demonstrated that vitamin D deficiency is common not only in patients with chronic liver diseases but also in those with hepatocellular carcinoma (HCC). Experimental studies have also demonstrated that vitamin D and its receptors are related to the occurrence of HCC and the prognoses of patients with HCC...

Four phosphorescent cyclometalated iridium(III) complexes containing benzimidazole moiety have been designed and synthesized. These Ir(III) complexes can inhibit several cancerous processes including cell migration, invasion, colony formation and angiogenesis effectively. Interestingly, they show much higher singlet oxygen quantum yield in acidic solution than in neutral solution. Upon irradiation at 425 nm with low energy (1.2 J·cm(-2)), they can induce apoptosis through lysosomal damage, evaluation of ROS level and activation of caspase-3/7...

High-mobility group AT-hook 2 (HMGA2), a member of the high mobility group family, has been reported to correlate with cancer progression. However, there is no report concerning the correlation between HMGA2 and metastasis in renal cell carcinoma. In the present study, we found that HMGA2 was highly expressed in five renal cell carcinoma cell lines compared with that in the normal renal tubular epithelial HK2 cell line. Additionally, HMGA2 facilitated cell migration and invasion of renal cell carcinoma cells, as evidenced by wound healing and Transwell assays...

Vacuolar ATPase (V-ATPase), widespread in eukaryotic cells, is extensively expressed in many highly metastatic tumors, of which the V-ATPase c subunit ATP6V0C is particularly associated with the invasion and metastasis of cancer. ATP6V0C was directly found to interact with LASS2/TMSG1 which is a new tumor metastasis inhibitory gene identified by our laboratory in 1999. In order to study the role of ATP6V0C, we generated small interference RNA (siRNA) targeting ATP6V0C and investigated its function on the invasion of human prostate cancer cell line PC-3M-1E8 with high metastatic potential and its interplay with LASS2/TMSG1...

Constitutive activation of TGF‑β signaling pathway is a well-documented mechanism responsible for the bone metastasis of prostate cancer (PCa). MicroRNAs (miRNAs) have been reported to be crucial for the activation of TGF‑β signaling via targeting downstream components of TGF‑β signaling pathway. Here, we report that miR‑19a‑3p is downregulated in bone metastatic PCa tissues and cells. Upregulation of miR‑19a‑3p suppresses invasion, migration in vitro and inhibits bone metastasis in vivo in PCa cells...

Tobacco smoke is a major risk factor for lung cancer. Epithelial‑mesenchymal transition (EMT) is decisive in cancer invasion and metastasis, and therefore promotes cancer progression. Mitogen‑activated protein kinase (MAPK) pathways are implicated in various aspects of cancer development and progression, including the EMT process. The chemopreventive effect of curcumin on carcinogenesis has been reported in vivo and in vitro. The present study investigated tobacco smoke‑induced alterations in the MAPK/activator protein‑1 (AP‑1) pathways, and pulmonary EMT changes in the lungs of mice, and further observed the chemopreventive effect of curcumin...

Tongue squamous cell carcinoma (TSCC) is more aggressive than other cancers in the head and neck region because of its potential for metastasis. Recently, β2‑adrenergic receptor (β2‑AR) has been reported to be a potential promoter in various types of solid cancer. However, the role of β2‑AR and its effect on TSCC is not well documented. Histological staining, western blot analysis, migration and invasion assay were used. In this study, the expression of β2‑AR was increased in TSCC tissue compared with adjacent non‑cancerous epithelium...

Metastasis is the primary cause of death in early-stage breast cancer. We evaluated the association between a metastasis biomarker, which we call "Tumor Microenviroment of Metastasis" (TMEM), and risk of recurrence. TMEM are microanatomic structures where invasive tumor cells are in direct contact with endothelial cells and macrophages, and which serve as intravasation sites for tumor cells into the circulation. We evaluated primary tumors from 600 patients with Stage I-III breast cancer treated with adjuvant chemotherapy in trial E2197 (NCT00003519), plus endocrine therapy for hormone receptor (HR)+ disease...

Non-small cell lung cancer (NSCLC) is the major cause of deaths among all the cancer types worldwide. Most of the NSCLC is diagnosed at an advanced stage and the 5-year overall survival rate is low. The reason for the low survival rate of patients with NSCLC is mainly due to distant metastasis. Matrine, a traditional Chinese medicine, has been shown a significant anti-proliferation and anti-invasive effect in tumors. However, little is known on the anti-invasive mechanism of matrine in lung cancer. Therefore, we tried to investigate the molecular mechanism of matrine on the invasive ability of NSCLC cells in vitro...

Background: Malignant pleural mesothelioma (MPM) is a rare disease with a relatively short overall survival (OS). Metalloproteinases (MMPs) have a vast biological effect on tumor progression, invasion, metastasis formation, and apoptosis. MMP expression was previously associated with survival in MPM. Our aim was to evaluate if genetic variability of MMP genes could also serve as a prognostic biomarker in MPM. Methods: We genotyped 199 MPM patients for ten polymorphisms: rs243865, rs243849 and rs7201, in MMP2; rs17576, rs17577, rs20544, and rs2250889 in MMP9; and rs1042703, rs1042704, and rs743257 in MMP14...

Cell motility plays an important role in intrahepatic metastasis of hepatocellular carcinoma (HCC), and predicts poor prognosis in patients. The present study investigated the role of a disintegrin and metalloproteinases (ADAMs) in HCC, since these proteins are known to be associated with cell motility. We confirmed the expression of 12 ADAMs with putative metalloproteinase activity in HCC cells, and established a KYN-2 HCC cell line stably expressing short interfering RNA against ADAM21 to investigate the effect of ADAM21 deficiency on HCC cell motility and metastasis in vitro and in vivo...

Cancer cells have more mutations in their mitochondrial DNA (mtDNA) than do normal cells, and pathogenic mutations in the genes encoding mitochondrial NADH dehydrogenase (ND) subunits have been found to enhance the invasive and metastatic ability of various tumour cells in animal experiments. However, it is unknown whether single-nucleotide variants (SNVs) of the ND genes that decrease complex I activity are involved in distant metastasis in human clinical samples. Here, we demonstrated the enhancement of the distant metastasis of Lewis lung carcinoma cells by the ND6 13885insC mutation, which is accompanied by the overexpression of metastasis-related genes, metabolic reprogramming, the enhancement of tumour angiogenesis and the acquisition of resistance to stress-induced cell death...

According to the REGARD and RAINBOW trials, ramucirumab(RAM)was introduced as second-line therapy for advanced or metastatic gastric cancer. RAM may impair wound healing due to the inhibition of angiogenesis; details on the postoperative course of patients who underwent surgery during RAM treatment remain unclear. Between 2011 and 2016, 93 patients with incurable gastric cancer were treated with RAM in our institute. Among them, 3 patients underwent surgery after RAM treatment. Case 1: A 74-year-old man with liver metastasis from gastric cancer was treated with a paclitaxel(PTX)plus RAM regimen...

Alternative splicing (AS) of pre-messenger (m)RNA is a pivotal mechanism in expanding proteomic diversity, which determines the functions of mammalian cells. By conducting transcriptome analyses to profile splicing events in human colorectal cancer (CRC) tissues compared to adjacent normal counterparts, we noted differential splicing profiles of serine/arginine-rich splicing factor 3 (SRSF3) and mitogen-activated protein 4 kinase 4 (MAP4K4) in cancerous tissues of CRC compared to adjacent normal tissues. In addition to SRSF3-mediated autoregulation, RNA-binding motif protein 4 (RBM4) constituted another mechanism in reprogramming the splicing profile of SRSF3...

The long non-coding RNA HOX transcript antisense RNA (HOTAIR) has been found overexpressed in many human malignancies and involved in tumor progression and metastasis. Although the downstream target through which HOTAIR modulates tumor metastasis is not well-known, evidence suggests that microRNA-197 (miR-197) might be involved in this event. In the present study, the significance of HOTAIR and miR-197 in the progression of colorectal cancer were detected in vitro and in vivo. We found that HOTAIR expression was significantly increased in colorectal cancer cells and tissues...
