MicroRNA (miRNA) are endogenous non-coding RNAs that suppress gene expression at the transcriptional, post-transcriptional or translational level by targeting the 3'-UTRs of specific mRNAs. miR-10a has been frequently reported to be aberrantly overexpressed in human tumors. In gastric cancer (GC), miR-10a has an important role in the metastasis from primary GC to lymph nodes. However, the role and relevant pathways of miR-10a in GC metastasis remain largely unknown. The present study was performed using 41 GC and 20 normal gastric mucosa tissues...

Surgery remains the most successful curative treatment for cancer. However, some patients with early-stage disease who undergo surgery eventually succumb to distant metastasis. Here, we show that in response to surgery, the lungs become more vulnerable to metastasis due to extracellular matrix remodeling. Mice that undergo surgery or that are preconditioned with plasma from donor mice that underwent surgery succumb to lung metastases earlier than controls. Increased lysyl oxidase (LOX) activity and expression, fibrillary collagen crosslinking, and focal adhesion signaling contribute to this effect, with the hypoxic surgical site serving as the source of LOX...

The S100 calcium-binding protein A4 (S100A4) induces epithelial mesenchymal transition, migration, invasion, angiogenesis and metastasis. Its induced expression in several cancer types correlates with poor prognosis. Apart from the functional and transcriptional regulatory aspects of S100A4, its post-transcriptional regulation is not yet clearly elucidated. In this study, we show that microRNAs (miR) miR-505-5p and miR-520c-3p target the 3'-UTR of S100A4 and inhibits its expression and its mediated migration and invasion...

The accurate preoperative detection and intraoperative navigation afforded by imaging techniques have had significant impact on the success of liver cancer surgeries. However, it is difficult to achieve satisfactory performance in both diagnosis and surgical treatment processes using any single modality imaging method. Here, we report the synthesis and characteristics of a novel dual-modality magnetic resonance imaging (MRI) and near-infrared fluorescence (NIRF) probe and verify its feasibility in nude mouse models with liver cancer...

Cerebral ischemia/reperfusion (I/R) injury leads to brain vascular dysfunction, which is characterized by endothelial cell injury or death. Long noncoding (lnc) RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) is reportedly associated with endothelial cell functions and dysfunctions. In the present study, the role of MALAT1 in I/R-induced cerebral vascular endothelial cell apoptosis was explored using oxygen-glucose deprivation and reoxygenation (OGD-R) as an in vitro I/R injury model. Primary human brain microvascular endothelial cells were cultured under OGD-R, and the expression levels of MALAT1 and cell apoptosis were measured at 6, 9, 12, 24 and 36 h post-reoxygenation...

Osteosarcoma (OS) is the most common malignant bone tumor in children and adolescents. The present study investigated the expression of Cytochrome P-450 (CYP) genes: CYP1A2, CYP3A4 and CYP3A5 by qRT-PCR in 135 specimens obtained from OS patients, including biopsy (pre-chemotherapy), tumor resected in surgery (post-chemotherapy), adjacent bone to tumor (nonmalignant tissue), pulmonary metastasis and adjacent lung to metastasis (nonmalignant tissue). Normal bone and normal lung tissues were used as control. We also investigated in five OS cell lines the modulation of CYPs expression by cisplatin, doxorubicin and methotrexate...

A 28 year old woman has suffered over the previous month from a post-traumatic swelling sensation of the left breast. Ultrasonography demonstrates a 9 cm, sharply-cut, rounded, hypo-echogenic lesion. Surgery is performed, with the hypothesis of an haematoma. The pathological analysis of the lesion shows a malignant phyllodes tumour with heterologous rhabdomyosarcomatous features. No metastasis is found. A radical mastectomy is performed and the patient benefits from an adjuvant radio-chemotherapy. Phyllodes tumours represent up to 1 % of all mammary cancers, with 10-20 % of malignant lesions...

Thyroid carcinoma usually presents as a neck lump. Distant metastasis as the sole initial manifestation of well-differentiated thyroid carcinoma (WDTC) is rare and little is known about these patients. The aim of this study is to characterize patients who present with distant metastasis as the sole initial manifestation of WDTC. Retrospective review of case records of WDTC seen at the National Cancer Centre Singapore from 2002 to 2015 was performed. Patients with no prior complaint of neck swelling and whose first presentation was distant metastatic WDTC were included...

As a genetic disease [1] cancer dysregulates key oncogenic pathways that influence cell growth, proliferation, survival, angiogenesis, and metastasis. Among the major determinants that enable cancer cells to acquire malignant traits are genomic diversity and instability. In the post human genome project era, cancer-specific genomic maps are redesigning tumor taxonomy. The treatment modalities, as well as the overall management of cancer as a disease in today's clinic, have started depending heavily on the molecular pathology of the individual tumor(s) in addition to the fundamental classification of cancers by histopathology...
