BACKGROUND: Emerging evidence demonstrated that hepatitis B virus X-interacting protein (HBXIP) has broad roles in cancers. However, high-level expression of HBXIP has been correlated with human malignancies, suggesting roles in carcinogenesis and tumor progression. The aim of the study is to investigate the role and mechanism of HBXIP oncogene and the correlation to the clinicopathological status in cervical cancers. METHODS: A total of 107 cervical cancer patients with strict follow-up, 105 cervical intraepithelial neoplasia (CIN) and 31 normal cervical epithelia samples were selected for immunohistochemical (IHC) staining of HBXIP protein...

Arsenic is a well-known toxic element and carcinogenic agent. The aim of this study was to investigate p63, E-cadherin, and β-catenin proteins in urothelial carcinoma (UC) in both arsenic contaminated areas [so-called blackfoot disease (BFD) area] and non-BFD areas. The expressions of p63, E-cadherin, and β-catenin proteins in 20 UC cases of blackfoot disease and 22 UC cases in non-BFD areas were detected using immunohistochemical methods. The results revealed a high p63 expression in 20 (47.6%) UC cases and high E-cadherin expression in six (14...

PURPOSE: Expression of the ΔN isoform of p63 (ΔNp63) is a diagnostic marker highly specific for lung squamous cell carcinoma (SCC). We previously found that Syntaxin Binding Protein 4 (STXBP4) regulates ΔNp63 ubiquitination, suggesting that STXBP4 may also be a SCC biomarker. To address this issue, we investigated the role of STXBP4 expression in SCC biology and the impact of STXBP4 expression on SCC prognosis. EXPERIMENTAL DESIGN: We carried out a clinicopathological analysis of STXBP4 expression in 87 lung SCC patients...

BACKGROUND: Women with diabetes have a worse survival after breast cancer diagnosis compared to women without diabetes. This may be due to a different etiological profile, leading to the development of more aggressive breast cancer subtypes. Our aim was to investigate whether insulin and non-insulin treated women with diabetes develop specific clinicopathological breast cancer subtypes compared to women without diabetes. METHODS AND FINDINGS: This cross-sectional study included randomly selected patients with invasive breast cancer diagnosed in 2000-2010...

A novel apatite mineral of Ba5(PO4)2SiO4 was synthesized successfully using a traditional high temperature solid-state reaction. Its structure was determined by high-resolution transmission electron microscopy, fast Fourier transform, energy dispersive X-ray spectroscopy, and X-ray powder diffraction Rietveld refinement, and this was found to be a hexagonal crystal system with the space group attributed to P63/m (176). Moreover, a series of Eu(2+) doped Ba5(PO4)2SiO4 phosphors were investigated. The photoluminescence (PL) properties of Ba5(PO4)2SiO4:Eu(2+) were investigated in detail by density functional theory calculations, diffuse reflection spectra, emission-excitation spectra, decay curves, and temperature dependence spectra...

Theranostic nanoparticles with combined imaging and therapy functions show great promise in cancer precision medicine. In this study, we constructed near-infrared (NIR) "OFF-ON" fluorescent nanohybrids (F-PNDs) for synchronous tumor imaging and microRNA (miRNA) modulation therapy against esophageal cancer. Nanodiamond clusters (NDs) were first functionalized for protamine sulfate immobilization (PNDs) on their surfaces via a noncovalent self-assembling approach and simultaneous encapsulation of NIR emitting fluorescence dye cyanine 5 (Cy-5) (F-PNDs)...

Complex [Fe3O(O2CPh)6(py)3]ClO4·py (1) crystallizes in the hexagonal P63/m space group, and its cation exhibits a crystallographically imposed D3h symmetry due to a C3 axis passing through the oxide of its {Fe3O}(7+) core. Single-crystal unit-cell studies carried out with synchrotron radiation confirmed that this symmetry is retained down to 4.5 K; a full crystal structure determination carried out at 90 K resolved the previously reported disorder of the perchlorate anion. Magnetic susceptibility and electron paramagnetic resonance (EPR) data for complex 1 were interpreted with a model considering the retention of the threefold crystallographic symmetry while predicting a lowering of the magnetic symmetry...

Loss-of-function mutations in SWI/SNF chromatin-remodeling subunit genes are observed in many cancers, but an oncogenic role for SWI/SNF is not well established. Here, we reveal that ACTL6A, encoding an SWI/SNF subunit linked to stem cell and progenitor cell function, is frequently co-amplified and highly expressed together with the p53 family member p63 in head and neck squamous cell carcinoma (HNSCC). ACTL6A and p63 physically interact, cooperatively controlling a transcriptional program that promotes proliferation and suppresses differentiation, in part through activation of the Hippo-YAP pathway via regulators including WWC1...

Benign cutaneous mixed tumor (chondroid syringoma) is the cutaneous counterpart of the benign mixed tumor (pleomorphic adenoma) of salivary glands, consisting of both epithelial and mesenchymal elements. The incidence of cutaneous mixed tumor is rare, composing < 0.01% of all primary skin tumors. Herein, we report a case of malignant mixed tumor which recurred in the right thumb 20 years after the reported initial diagnosis of a benign mixed tumor at this site. Histologically, the lesion consisted of highly atypical and infiltrative cells in cords and ductal structures, with an adjacent focus of residual benign mixed tumor present...

BACKGROUND: Metaplastic breast carcinoma (MBC) is a rare type of breast cancer and its diagnosis in routine practice can be challenging and may require immunohistochemical (IHC) characterisation if no conventional invasive or in situ carcinoma is present. Previous IHC studies of MBC often had a small sample size and did not investigate the different histological subtypes. This study aimed to assess the immunoprofile of MBC subtypes in a large series. METHODS: 172 MBC diagnosed in routine and referral practice in Nottingham over 26 years were reviewed by 3 breast pathologists...

We have synthesized a novel inorganic-organic hybrid nanostructure (IOHN) composed of fluoride nanophosphor (NaGd0.78Er0.02Yb0.2F4) and β-diketones complex (Eu(DBM)3Phen). The Le Bail fitting of X-ray diffraction data suggests that the nanophoshor crystallizes in a hexagonal structure (P63/m space group). The TEM studies reveal that the nanophosphor and the IOHN both have average particle size of 6-8nm. The Eu(DBM)3Phen and NaGd0.78Er0.02Yb0.2F4 show characteristic down-shifting (DS) and up-conversion (UC) emission, under UV and NIR excitation, respectively...

Our previous study demonstrated that conditional reprogramming (CR) allows the establishment of patient-derived normal and tumor epithelial cell cultures from a variety of tissue types including breast, lung, colon and prostate. Using CR, we have established matched normal and tumor cultures, GUMC-29 and GUMC-30 respectively, from a patient's prostatectomy specimen. These CR cells proliferate indefinitely in vitro and retain stable karyotypes. Most importantly, only tumor-derived CR cells (GUMC-30) produced tumors in xenografted SCID mice, demonstrating maintenance of the critical tumor phenotype...

Twenty new rare-earth metal rich intermetallic aluminium compounds, RE10TAl3 (RE = Y, Ho, Tm, Lu; T = Fe, Co, Ni, Ru, Rh, Pd, Os, Ir, Pt), were synthesized by arc melting the elements. The compounds crystallize, in analogy to e.g. the respective Cd representatives, with a ternary ordered structure as anti-type to the hexagonal Co2Al5 type, with the space group P63/mmc. The three crystallographically independent rare-earth metal sites occupy the aluminium positions of the aristotype, while the transition metal and aluminium atoms are ordered on the two cobalt sites...

BACKGROUND: In the Western World malignant mesothelioma (MM) is most prevalent in the pleura of older males professionally exposed to asbestos. Information about MM from rapidly industrializing countries, such as China, is minimal. There is concern that a proportion of MM diagnoses in China may be incorrect because most Chinese physicians do not have experience diagnosing this rare cancer. We recently reported an unusual high incidence of peritoneal MM among Eastern Chinese female patients...
