Fibroblast growth factor 19 (FGF19) promotes tumor growth in various types of cancer, but its function has not been investigated in the context of colorectal adenoma. Here, we report that FGF19 expression was greater in colorectal adenoma than in normal tissues, as measured by an enzyme-linked immunosorbent assay, quantitative reverse-transcription PCR and immunohistochemistry. FGF19 expression was also elevated in a subset of human colon cancer cell lines. Moreover, FGF receptor 4 (FGFR4), the cognate receptor for FGF19, was upregulated in colorectal adenoma tissues...

Eight Ti(iv) compounds 1-8, of the type [Ti(Ln)2] where Ln is a variously substituted dianionic tridentate acylhydrazone, were synthesized by reacting the appropriate hydrazide with 2-hydroxybenzaldehyde or 2'-hydroxyacetophenone and titanium(iv) tetra(isopropoxide) in a 2 : 2 : 1 molar ratio. The solid-state structures of 1-6 and 7·CH2Cl2 were deduced from the single crystal X-ray diffraction data, which indicated that each L2- ligand is fully deprotonated and coordinated to the Ti(iv) cation via the enolic oxygen, the imino nitrogen and the phenolic oxygen atoms (ONO donor set) in an enol tautomeric form, the metal assuming the distorted octahedral geometry...

We have shown that cytoplasmic actin isoforms play different roles in neoplastic cell transformation. β-Cytoplasmic actin acts as a tumor suppressor, affecting epithelial differentiation, cell growth, cell invasion and tumor growth of colon and lung carcinoma cells. In contrast, γ-cytoplasmic actin enhances malignant features of tumor cells whose actin network regulation is carried out via the γ-actin isoform. The goal of this study was to describe the role of cytoplasmic actins in cell cycle regulation of breast cancer cell lines MCF-7 and MDA-MB-231...

Amide substituted (Z)-β-enaminones were synthesized by green chemistry and stereo-specific synthetic pathway as novel phosphoinositide 3-kinase (PI3K) inhibitors and breast cancer drugs. PI3K inhibition was measured by competitive ELISA. A panel of cancer cell lines including MCF-7 (breast cancer), G-361 (skin cancer), and HCT 116 (colon cancer) were used to assess the anticancer potentials. In the PI3K assay, 2c and 2f were indolent for the proposed inhibitory action, which was recognized from the obtained IC50 (>1...

TMEM16A (also known as anoctamin 1, ANO1) is the molecular basis of the calcium-activated chloride channels, with ten transmembrane segments. Recently, atomic structures of the transmembrane domains of mouse TMEM16A (mTMEM16A) were determined by single-particle electron cryomicroscopy. This gives us a solid ground to discuss the electrophysiological properties and functions of TMEM16A. TMEM16A is reported to be dually regulated by Ca2+ and voltage. In addition, the dysfunction of TMEM16A has been found to be involved in many diseases including cystic fibrosis, various cancers, hypertension, and gastrointestinal motility disorders...

Chronic inflammation of the colon (colitis) is a risk factor for colorectal cancer (CRC). Hormone-replacement therapy reduces CRC incidences, and the estrogen receptor beta (ERβ/ESR2) has been implicated in this protection. Gut microbiota is altered in both colitis and CRC and may influence the severity of both. Here we test the hypothesis that intestinal ERβ impacts the gut microbiota. Mice with and without intestine-specific deletion of ERβ (ERβKOVil ) were generated using the Cre-LoxP system. Colitis and CRC were induced with a single intraperitoneal injection of azoxymethane (AOM) followed by administration of three cycles of dextran sulfate sodium (DSS) in drinking water...

Recent studies have shown that overexpression of metastasis-associated in colon cancer 1 (MACC1) is significantly associated with adverse prognoses of patients with different kinds of cancer. However, the exact survival effect of MACC1 on epithelial ovarian cancer (EOC) patients has not yet been established. Thus, the objective of this study was to explore the prognostic role of MACC1 mRNA in EOC by using Kaplan-Meier (KM) plotter and ONCOMINE database. Our results indicated that MACC1 mRNA high expression was significantly associated with unfavorable overall survival (hazard ratio (HR) = 1...

Bone marrow stromal antigen 2 (BST-2) mediates various facets of cancer progression and metastasis. Here, we show that BST-2 is linked to poor survival in invasive breast cancer patients as its expression positively correlates with disease severity. However, the mechanisms that drive the pro-metastatic functions of BST-2 are not fully understood. Correlation of BST-2 expression and tumor aggressiveness was analyzed in human tissue samples. Migration, invasion, and competitive experimental metastasis assays were used to measure the cellular responses after silencing BST-2 expression...

BACKGROUND: Perforated colon cancer is a rare complication, but has a high risk of recurrence. However, most studies have not distinguished sealed-off perforation from free perforation, and the prognosis is unclear. The aim of this study was to evaluate the oncologic outcome of colon cancer with sealed-off perforation. METHODS: Eighty-six consecutive patients who underwent resection for colon cancer with sealed-off or free perforation were included. We defined sealed-off perforation as a colon perforation with localized abscess identified on operative, computed tomography, or pathologic findings, with no evidence of free perforation, including fecal contamination and dirty fluid collection in the peritoneal cavity...

INTRODUCTION: Colorectal cancer (CRC) remains the second most common cancer in women worldwide. Physical activity (PA) has been associated with reduced risk of CRC; however, this has been demonstrated more consistently in men, while results of studies in women have been largely equivocal. We aimed to further examine the relationship between PA patterns and the risk of CRC in women, using repeated measurements. METHODS: We followed participants of the Norwegian Women and Cancer (NOWAC) Study - a nationally representative cohort...

BACKGROUND: Epidemiological studies and cardiovascular prevention trials have shown that low-dose aspirin can reduce colorectal cancer (CRC) incidence and mortality, including inhibition of distant metastases. Metformin has also been associated with decreased colon adenoma recurrence in clinical trials and lower CRC incidence and mortality in epidemiological studies in diabetics. While both drugs have been tested as single agents, their combination has not been tested in cancer prevention trials...

BACKGROUND: pN stage in the TNM classification has been the "gold standard" for lymph node staging of colorectal carcinomas, but this system recommends collecting at least 12 lymph nodes for the staging to be reliable. However, new prognostic staging systems have been devised, such as the ganglion quotients or lymph node ratios and natural logarithms of the lymph node odds methods. The aim of this study was to establish and validate the predictive and prognostic ability of the lymph node ratios and natural logarithms of the lymph node odds staging systems and to compare them to the pN nodal classification of the TNM system in a population sample of patients with colon cancer...
