The expression profiles of long noncoding RNAs (lncRNAs) in colorectal cancer (CRC) have remained unclear. LncRNA AB073614 is known to be upregulated in ovarian cancer and glioma tissues, and is associated with the occurrence and progression of those cancers. In the present study, we investigated the lncRNA AB073614 gene expression patterns in CRC cell lines and tissue samples from CRC patients, and then analyzed them for possible associations with various clinicopathological characteristics. Furthermore, the roles played by lncRNA AB073614 in CRC cell proliferation, apoptosis, cell cycle progression, migration, and invasion were examined in vitro by using gene knockdown and overexpression techniques...

Gastric cancer is one of the most of common cancers in the world. 5-Fluorouracil (5-FU) has been identified as one of the standard first-line chemotherapy drugs for locally advanced or metastatic gastric cancer. However, poor tumor penetration, bad selectivity and toxic side effects are the major limitations for the application of chemotherapy drugs in anticancer therapy. Recently, plenty of studies demonstrate that the novel tumor-homing peptide iRGD could promote the tumor-penetrating capability of chemotherapy drugs in multiple cancers, and neuropilin-1 (NRP1) protein is the critical mediator for iRGD...

Accumulating evidences have shown that microRNAs (miRNAs) are vital regulators and possess huge capabilities in post-transcriptional control. Although a large number of miRNAs have been identified to be dysregulated in human cancers especially in colon cancer, our understandings of the function of most miRNAs are still largely limited. In this study, we have demonstrated that miR-299-3p plays a critical role in suppressing colon carcinoma progression by targeting Vascular Endothelial Growth Factor A (VEGFA)...

Developmental pathways (e.g., Notch, Hippo, Hedgehog, Wnt, and TGF-β/BMP/FGF) are networks of genes that act co-ordinately to establish the body plan, and disruptions of genes in one pathway can have effects in related pathways and may result in serious dysmorphogenesis or cancer. Interestingly, all developmental pathways are highly conserved cell signalling systems present in almost all multicellular organisms. In addition, they have a crucial role in cell proliferation, apoptosis, differentiation, and finally in organ development...

PURPOSE: Keratinization is a routinely reported histologic feature in head and neck cancer. In contrast to numerous clinicopathologic parameters, the prognostic value of keratinization in oral squamous cell carcinoma (OSCC) is rarely reported in the literature. The purpose of this study was to review the outcome of patients with OSCC with a special focus on the degree of keratinization. PATIENTS AND METHODS: In this retrospective cohort study, we evaluated the medical records at the Department of Oral and Maxillofacial Surgery, Jena University Hospital, and investigated the outcome of patients with OSCC with disease-free survival and disease-specific survival according to the degree of keratinization...

Triosephosphate isomerase (TPI) is highly expressed in many types of human tumors and is involved in migration and invasion of cancer cells. However, TPI clinicopathological significance and malignant function in gastric cancer (GC) have not been well defined. The present study aimed to examine TPI expression in GC tissue and its biological functions. Furthermore, we investigated its downstream genes by gene chip technology. Our results showed that TPI expression was higher in gastric cancer tissues than adjacent tissues, although no statistical differences were found between TPI expression and clinicopathological factors...

Zinc finger protein 687 (ZNF687), identified as a C2H2 zinc finger protein, has been found to be mutated and upregulated in giant cell tumor of bone and acute myeloid leukemia, suggesting an oncogenic role for ZNF687 in cancer. However, the clinical significance and precise role of ZNF687 in cancer progression are largely unknown. Herein, we report that ZNF687 was markedly upregulated in hepatocellular carcinoma (HCC) cell lines and HCC tissues, and was significantly correlated with relapse-free survival in HCC...

The medical burden of heart failure (HF) has spurred interest in clinicians and scientists to develop therapies to restore the function of a failing heart. To advance this agenda, the National Heart Lung Blood Institute (NHLBI) convened a Working Group of experts on June 2-3, 2016 in Bethesda Maryland to develop recommendations for the NHLBI aimed at advancing the science of cardiac recovery in the setting of mechanical circulatory support (MCS). MSC devices effectively reduce volume and pressure overload that drives the cycle of progressive myocardial dysfunction, thereby triggering structural and functional reverse remodeling...

Skin cancer is the most common cancer in the United States with over 3.5M annual cases. Presently, visual inspection by a dermatologist has good sensitivity (> 90%) but poor specificity (< 10%), especially for melanoma, which leads to a high number of unnecessary biopsies. Here we use dynamic thermal imaging (DTI) to demonstrate a rapid, accurate and non-invasive imaging system for detection of skin cancer. In DTI, the lesion is cooled down and the thermal recovery is recorded using infrared imaging. The thermal recovery curves of the suspected lesions are then utilized in the context of continuous-time detection theory in order to define an optimal statistical decision rule such that the sensitivity of the algorithm is guaranteed to be at a maximum for every prescribed false-alarm probability...

Colorectal cancer patients have a high incidence of liver metastasis (ml-CRC). Surgical resection is the gold standard for treatment of hepatic metastasis but only a small percent of patients are traditional candidates based on disease extent and adequate size of the future liver remnant (FLR). Interventions such as portal vein embolization (PVE) and associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) are performed to increase FLR for operative conversion. Limitations to PVE include intrahepatic disease progression, portal vascular invasion, and utilization with concurrent chemotherapy...

PURPOSE: Although already established for very-low and low-risk (LR) prostate cancer (PCa), controversy remains around offering active surveillance (AS) to men with intermediate-risk (IR) PCa. As IR represents a broad spectrum of disease biology, there is a critical need to define eligibility criteria that will enable both patient and physician to accept AS as the best balance of competing risks. In this study, we aimed to identify predictors of progression to enable optimal patient selection...

Melanoma incidence has been increasing in light-skinned populations worldwide, but the reasons for the increase have been controversial. Our prior assessment in California non-Hispanic whites showed substantial increases in invasive melanoma incidence for tumors of all thicknesses in all neighborhoods categorized by socioeconomic status (SES) between 1988-1992 and 1998-2002. To understand whether these trends continued, we updated our assessment to include the diagnosis period 2008-2012 and more accurate pathologic stage at diagnosis...

Maternal smoking during pregnancy is known to be related to adverse pregnancy results associated with trophoblast proliferation and cell cycle progression. Moreover, many previous studies have shown that cigarette smoke is correlated with human chorionic gonadotropin beta (hCG-β) subunit produced from syncytiotrophoblasts during pregnancy. Thus, we further investigated whether cigarette smoke extract (CSE) affects the cell proliferation, migration and endocrine hormone activity of JEG-3 human placental cancer cells...

Epstein-Barr virus (EBV)-encoded latent membrane protein 1 (LMP1) is an oncoviral protein that plays a pivotal role in EBV-induced oncogenic transformation. The function of LMP1 in EBV-induced oncogenesis has been well studied. However, the molecular mechanisms underlying LMP1 protein stability remain poorly understood. In this study, we found that ribosomal protein s27a (RPS27a) regulates LMP1 stability by a tandem affinity purification analysis. RPS27a interacts directly with LMP1 in vitro and in vivo. Furthermore, overexpression of RPS27a increases the half-life of LMP1 in 293T cells, whereas downregulation of RPS27a using lentiviral shRNA technology accelerates the decrease in LMP1 protein level in EBV-transformed B cells...
