OBJECTIVE: To identify candidate microRNAs that potentially regulate the initiation and progression of osteoarthritis. METHODS: Osteoarthritis was induced in 10-12 week old male wild-type C57BL6 mice and in mice resistant to aggrecanase cleavage (Acan p.374ALGS→374NVYS) by destabilization of the medial meniscus (DMM). Osteoarthritis pathology was scored histologically. RNA from cartilage and subchondral bone were harvested in parallel by laser micro-dissection at 1 and 6 weeks post-surgery...

Primary intraocular lymphomas are rare tumours that can be further subdivided into primary vitreoretinal and the even rarer primary uveal lymphoma. The incidence of primary vitreoretinal lymphoma (PVRL) has increased during the last few decades. Differential diagnostic distinction between lymphoma and posterior uveitis is often difficult, so that adequate diagnosis and treatment is often delayed. This is fatal, because PVRL is often associated with primary central nervous lymphoma. To confirm the diagnosis, prior treatment of cytological or histological detection of lymphoma cells is the gold standard...

OBJECTIVES: The management of bronchopulmonary neuroendocrine tumours (BPNETs) is difficult, since imaging, histology and biomarkers have a limited value in diagnosis, predicting outcome and defining therapeutic efficacy. We evaluated a NET multigene blood test (NETest) to diagnose BPNETs, assess disease status and evaluate surgical resection. METHODS: (i) Diagnostic cohort: BP carcinoids (n = 118)-typical carcinoid, n = 67 and atypical carcinoid, n = 51; other lung NEN (large-cell neuroendocrine carcinoma and small-cell lung carcinoma, n = 13); adenocarcinoma, (n = 26); squamous cell carcinoma (n = 23); controls (n = 90) and chronic obstructive pulmonary disease (n = 18)...

In the past few decades, great conceptual and technological advances have been made in the field of toxicology, but animal model-based research still remains one of the most widely-used and readily available tools for furthering our current knowledge. However, animal models are not perfect in predicting all systemic toxicity in humans. Extrapolating animal data to accurately predict human toxicities remains a challenge, and researchers are obligated to question the appropriateness of their chosen animal model...

Prostate cancer research is hampered by the lack of in vivo preclinical models that accurately reflect patient tumour biology and the clinical heterogeneity of human prostate cancer. To overcome these limitations we propagated and characterised a new collection of patient-derived prostate cancer xenografts. Tumour fragments from 147 unsupervised, surgical prostate samples were implanted subcutaneously into immunodeficient Rag2-/-γC-/- mice within 24 hours of surgery. Histologic and molecular characterisation of xenografts was compared with patient characteristics, including androgen-deprivation therapy, and exome sequencing...

Autoimmune hepatitis is a chronic inflammatory disease in the liver with potential to the development of liver fibrosis. Recent evidences suggest that bone marrow derived mesenchymal stem cells (BMSCs) may exert its therapeutic activity through exosomes. Moreover, miR-223 is highly expressed in BMSCs and plays an important role in autoimmune diseases. Therefore, in this study, hepatoprotective role of BMSCs and miR-223 was investigated in both mice and hepatocytes. Liver antigen S100 was used to establish autoimmune hepatitis model in mice while LPS and ATP were used to establish cell injury model in hepatocyte...

Renal cell carcinoma (RCC) is a heterogeneous histological disease and the most common kidney cancer. The mortality rate of RCC remains high despite the improved treatment. Sinomenine is an isoquinoline extracted from Chinese medicinal plant Sinomenium acutum, famous for its ability to suppress several cancer cell types. Our research aimed to explore the anti-cancer potential of sinomenine in RCC. Results showed that sinomenine reduced the viability by reducing sphere-forming ability and enhancing pro-apoptosis effect in ACHN cells in a dose dependent manner...

PURPOSE: Phyllodes tumors (PTs) of the breast are rare, accounting for less than 1% of all breast tumors. Among PTs, malignant PTs (MPTs) have malignant characteristics and distant metastases occur in about 20% to 30% of MPTs. However, there is no effective treatment for MPTs with distant metastasis, resulting in an abject prognosis. We performed targeted deep sequencing on PTs to identify the associations between genetic alterations and clinical prognosis. METHODS: We performed targeted deep sequencing to evaluate the genetic characteristics of PTs and analyzed the relationships between clinical and genetic characteristics...
