Stromal carcinoma-related fibroblasts (CAFs) are the main type of non-immune cells in the tumor microenvironment (TME). CAFs interact with cancer cells to promote tumor proliferation. Long non-coding RNAs (lncRNAs) are known to regulate cell growth, apoptosis, and metastasis of cancer cells, but their role in stromal cells is unclear. Using RNA sequencing, we identified a stromal lncRNA signature during the transformation of CAFs from normal fibroblasts (NFs) in oral squamous cell carcinoma (OSCC). We uncovered an uncharacterized lncRNA, FLJ22447, which was remarkably up-regulated in CAFs, referred to LncRNA-CAF (Lnc-CAF) hereafter...

Metastasis is responsible for the majority of cancer associated fatalities. Tumor cells leaving the primary tumor and entering the blood flow immediately interact with platelets. Activated platelets contribute in different ways to cancer cell survival and proliferation, e.g. in formation of the early metastatic niche by release of different growth factors and chemokines. Here we show that a direct interaction between platelets and MV3 melanoma or MCF7 breast cancer cells induces platelet activation and a VEGF release in citrated plasma that cannot be further elevated by the coagulation cascade and generated thrombin...

Cancer is a major cause of death. The outcomes of current therapeutic strategies against cancer often ironically lead to even increased mortality due to the subsequent drug resistance and to metastatic recurrence. Alternative medicines are thus urgently needed. Cumulative evidence has pointed out that pterostilbene (trans-3,5-dimethoxy-4-hydroxystilbene, PS) has excellent pharmacological benefits for the prevention and treatment for various types of cancer in their different stages of progression by evoking apoptotic or nonapoptotic anti-cancer activities...

An area that has come to be of tremendous interest in tumor research in the last decade is the role of the microenvironment in the biology of neoplastic diseases. The tumor microenvironment (TME) comprises various cells that are collectively important for normal tissue homeostasis as well as tumor progression or regression. Seminal studies have demonstrated the role of the dialogue between cancer cells (at many sites) and the cellular component of the microenvironment in tumor progression, metastasis, and resistance to treatment...

Immune checkpoint inhibitor therapy has been clinically introduced for several malignancies, and its effectiveness has been confirmed by clinical trials. In particular, programmed cell death protein 1 (PD-1) and programmed death-ligand 1 (PD-L1) are widely known as important immune checkpoint molecules associated with the mechanisms of immune escape by malignant tumor cells. On the other hand, liquid biopsy of blood specimens has the clinical benefit of providing a simple, repeatable sampling tool. Non-invasive liquid biopsy has recently been spotlighted as a promising approach to predicting tumor progression and prognosis...

CD73, also known as ecto-5'-nucleotidase (eN, NT5E, EC3.13.5), is the rate-limiting enzyme for adenosine generation and is expressed on multiple cells. Its expression is significantly influenced by hypoxia and inflammatory factors. During inflammation, CD73 protects endothelial barrier function and inhibits leukocyte trafficking. CD73 also promotes M2 macrophages (anti-inflammatory phenotype). In addition, CD73 is expressed on Treg cells and mediates immune suppression through adenosine. CD73 serves as an essential regulator for the immunity and inflammation...

Transforming growth factor-β (TGF-β) signaling pathway is a key network in cell signaling that controls vital processes such as proliferation, differentiation, apoptosis, epithelial-mesenchymal transition, and migration, thus acting as a double-edged sword in normal development and diseases, in particular organ fibrosis, vascular disorders, and cancer. Early in tumorigenesis, the pathway exerts anti-tumor effects through suppressing cell cycle and inducing apoptosis, while during late stages, it functions as a tumor promoter by enhancing tumor invasiveness and metastasis...

Obesity is a risk factor for cancer incidence and cancer mortality. The association of obesity and cancer is attributed to multiple factors, but the tightest linkage is with the chronic, low-grade inflammation that accompanies obesity. Myeloid-derived suppressor cells (MDSC) are known facilitators of cancer progression that act by suppressing the activation and function of tumor-reactive T cells. Because MDSC quantity and function are driven by chronic inflammation, we hypothesized that MDSC may accumulate in obese individuals and facilitate tumor growth by suppressing antitumor immunity...

Long non-coding RNAs are known as key regulators in the progression and metastasis of breast cancer. Miat originally has been considered as an lncRNA to be associated with a susceptibility to myocardial infarction. Here, we have detected the expression of Miat in different cancer cells and a series of breast tumor tissue. Miat expression was much higher in high-grade tumors compared to low-grade ones. Unlike P53 positive tumors, Miat expression was upregulated in ER, PR, Her2 positive tumor tissues. Knockdown Miat suppressed breast cancer cell proliferation and caused G1 arrest in cell cycle...

CKLF-like MARVEL transmembrane domain containing 3 (CMTM3) is considered to be a tumor suppressor gene in multiple types of malignancies. Previous studies have indicated that CMTM3 suppresses metastasis and epithelial-mesenchymal transition (EMT) in gastric cancer. However, its role in gastric cancer cell proliferation has rarely been discussed. Moreover, the regulatory mechanisms of CMTM3 in gastric cancer remain unclear. In this study, RT‑qPCR and IHC were used to assess the expression of CMTM3 and miR‑135b‑5p in gastric cancer tissues and cell lines...

Brain-derived neurotrophic factor (BDNF) has previously been demonstrated to be associated with several types of cancer. In addition, its receptor, tropomyosin related kinase B (TrkB) is involved in tumor invasion and metastasis. Epithelial-mesenchymal transition (EMT) is associated with metastasis in cancers. Thus, The aim of the present study was to examine whether BDNF/TrKB expression is linked to a poor survival and the acquisition of the EMT phenotype in cervical cancer. We found that a high positive expression of BDNF/TrKB was associated with poor survival in cervical cancer...

Recent studies have indicated that long noncoding RNAs (lncRNAs) play a pivotal role in almost all physiological cellular processes, including every stage of cancer development. Given that hypoxia in the tumor microenvironment is involved in the malignant behavior of tumors, such as invasion and metastasis, we investigated the cytoplasmic and nuclear localization of lncRNAs in colorectal cancer cells. A cell culture under hypoxic conditions revealed several lncRNAs, such as LINC00152, whose levels were increased in the cytoplasm of colorectal cancer cells...

In the tumor microenvironment, soluble molecules play important role in the establishment of a pre-metastatic niche. The S100 calcium-binding protein family are inflammatory molecules that contribute to the development of a pro-inflammatory tumor microenvironment. S100B belongs to the S100 family and serum S100B (also known as S100beta) serves as a marker for metastasis in lung cancer, ovarian cancer and melanoma. However, the association between S100B and the metastasis of breast cancer is not yet well understood...

The effect of intermittent calorie restriction (ICR) on cancer is controversial. In this study, we examined the effects of ICR and food content in syngeneic BALB/c mice injected with CT26 mouse colon cancer cells. Mice were subjected to 24-h fasting once a week for 4 weeks, and then provided with a control, high-calorie, or trans fatty acid-rich diet. While ICR resulted in increases in tumor weights, metastasis and in the number of cancer stem cells (CSCs) in the tumors or blood of mice fed the control and high-fat diets, it had no effect on body weight after 4 weeks...

Prostate cancer is a widespread problem among men, with >160 000 new cases in 2017 alone. Androgen deprivation therapy is commonly used in prostate cancer treatment to block androgens required for cancer growth, but disease relapse after androgen deprivation therapy is both common and severe. Changes in androgen receptor signaling from androgen deprivation therapy have been linked to therapeutic resistance and tumor progression. Resistant cells can become reprogrammed to undergo epithelial-mesenchymal transition, a phenotypic switch from benign, epithelial cells to a mobile cell with mesenchymal traits...

The mouse model characterized by spontaneous lung metastasis from JygMC (A) cells closely resembles the human triple negative breast cancer (TNBC) subtype. The primary tumors morphologically present both epithelial and spindle-like cells, but metastases in lung parenchyma display only adenocarcinoma properties. In the study of molecular signatures, laser capture microdissection (LCM) on frozen tissue sections was used to separate the following regions of interest: the epithelial-mesenchymal transition (EMT), mesenchymal-epithelial transition (MET), carcinoma, lung metastases, normal mammary gland and normal lung parenchyma...

Adeno-associated virus 2 (AAV2) is prepotent in the biological treatment of breast tumor because of its low pathogenicity and immunogenicity. Our previous study demonstrated that insulin‑like growth factor‑binding protein 2 (IGFBP‑2) was highly expressed in patients with breast metastasis. In the present study, the effects of recombinant AAV2 on the growth and metastasis of breast cancer cells were determined in vitro, and in vivo. rAAV2-ZsGreen-shRNA-scramble and rAAV2‑ZsGreen‑shRNA‑hIGFBP‑2 were used to transfect MDA‑MB‑468, and MCF‑10A cells respectively, and observed that these virus could not penetrate the normal human breast epithelia MCF‑10A cell line...
