miR-137 suppresses proliferation, migration and invasion of colon cancer cell lines by targeting TCF4.

Colorectal cancer is cancer of the colon or rectum and is the third most prevalent form of cancer. Currently, there are several shortcomings in the prognosis and early detection of colon cancer. The present study aims to address questions pertaining to the role of microRNA (miR)-137 in colon cancer progression and the mode of regulation.

Downregulation of PDCD4 by miR-21 suppresses tumor transformation and proliferation in a nude mouse renal cancer model.

Programmed cell death 4 (PDCD4) is known to suppress neoplastic transformation, cell proliferation and metastasis, and to be downregulated by microRNA-21 (miR-21) in renal cell carcinoma (RCC) cell lines and tissues. The aim of the present study was to investigate the roles of and association between PDCD4 and miR-21 in a nude mouse renal cancer model. A total of 24 BALB/c male nude mice were randomly assigned into the following three groups: Negative control (NC; n=8), miR-21 inhibitor (n=8) and miR-21 mimic (n=8).

Tanshinone IIA protects against myocardial ischemia reperfusion injury by activating the PI3K/Akt/mTOR signaling pathway.

Objective: To determine the mechanism by which Tanshinone IIA (Tan IIA) relieves myocardial ischemia reperfusion injury (MIRI) in rats via the PI3K/Akt/mTOR signaling pathway.

Methods: Sprague-Dawley (SD) rats received an intravenous injection of Tan IIA and LY294002 and were divided into the sham, control (myocardial ischemia reperfusion), Tan-L (low-dose Tan IIA), Tan-H (high-dose Tan IIA), Tan-L+LY (low-dose Tan IIA+LY294002), Tan-H+LY (high-dose Tan IIA+LY294002) and LY (LY294002) groups. Cardiomyocytes obtained from neonatal rats were treated with hypoxia reoxygenatin, Tan IIA and LY294002 and divided into the blank, control, Tan-L, Tan-H, Tan-L+LY, Tan-H+LY and LY groups.

The Effect and Mechanisms of Proliferative Inhibition of Crocin on Human Leukaemia Jurkat Cells.

Targeted therapy is a potentially useful approach for the treatment of T-lineage acute lymphoblastic leukaemia. This study aimed to find a highly effective, low toxic anti-tumour drug and further investigate its mechanisms. Jurkat cells were used as the object and were stimulated by different concentrations of crocin.

Decreased microRNA-198 expression and its prognostic significance in human glioma.

Previous evidence has shown the association of aberrant miR-198 expression with tumorigenesis and progression of many human malignancies. However, its involvement in human glioma is still unclear. Therefore, the aim of the current study was to investigate the expression and function of miR-198 in human gliomas.

Decreased expression of miR-874 and its tumor suppressive function in human colorectal cancer.

Dysregulation of miRNAs is associated with cancer development and progression. For example, aberrant expression of miR-874 has been found in some types of cancer. However, miR-874 expression and its clinical significance in colorectal cancer (CRC) have not yet been explored.

Effects of First High-Dose Atorvastatin Loading in Patients With ST-Segment Elevation Myocardial Infarction Undergoing Percutaneous Coronary Intervention.

To determine the effects of 80-mg atorvastatin administration for the first time in patients with acute ST segment elevation myocardial infarction (STEMI) before emergency percutaneous coronary intervention (PCI). A total of 118 patients with STEMI who underwent emergency PCI were enrolled in this study. The patients were divided into 80-mg group (n = 59) and 40-mg group (n = 59), according to the loading dose of atorvastatin firstly before operation.

5-Hydroxy-3,6,7,8,3',4'-hexamethoxyflavone, a polymethoxyflavone, exerts antitumor effect on PI3K/Akt signaling pathway in human gastric cancer cell BGC-7901.

5-Hydroxy-3,6,7,8,3',4'-hexamethoxyflavone (5HHMF), a polymethoxyflavone (PMF) mainly found in citrus plants, exhibits excellent physiological functions. In this study, we aimed to investigate the anticancer activity of 5HHMF against human gastric cancer cell BGC-7901 both in vitro and in vivo and illustrate the potential mechanisms. The proliferation of BGC-7901 cells was assessed by MTT assay.

Resveratrol induces apoptosis in K562 cells via the regulation of mitochondrial signaling pathways.

Resveratrol, an edible polyphenolic phytoalexin obtained primarily from root extracts of the oriental plant, Polygonum cuspidatum and from grapes and red wine, has been reported as an anticancer compound against several types of cancer, the accurate molecular mechanisms of by which it induces apoptosis are limited. In the present study, the molecular mechanisms of resveratrol on human leukemia K562 cells apoptosis was examined. Our results showed that resveratrol significantly decreased cell viability and triggered cell apoptosis in K562 cells.

Prevalence of Thrombocytopenia and Its Association with Serum Magnesium.

The present study aimed to investigate the prevalence of thrombocytopenia and its association with serum magnesium in a nationally representative cohort. A total of 8478 participants aged 18 years and over were recruited in a cross-sectional survey. Thrombocytopenia was defined as platelet count less than 150 × 10(9)/L.

No association of single nucleotide polymorphisms involved in GHRL and GHSR with cancer risk: a meta-analysis.

Background: Ghrelin was associated with several of cancers. The conflict results of SNPs with GHRL and GHSR gene were demonstrated in different studies. Thus, this meta-analysis is to evaluate the associations.

Involvement of IGF-1 and MEOX2 in PI3K/Akt1/2 and ERK1/2 pathways mediated proliferation and differentiation of perivascular adipocytes.

Perivascular adipocyte (PVAC) proliferation and differentiation were closely involved in cardiovascular disease. We aimed to investigate whether phosphatidylinositol 3-kinase (PI3K) and mitogen-activated protein kinase (MAPK) signaling pathways enhance PVAC functions activated by insulin-like growth factor 1(IGF-1) and suppressed by mesenchyme homeobox 2 (MEOX2). In this study, PVACs from primary culture were cultured and induced to differentiate.

Primary cutaneous sweat gland carcinoma.

Primary cutaneous sweat gland carcinoma is a rare neoplasm of malignant sweat gland lesions. It is characterized clinically with non-symptomatic, slow-growing nodules. We report the case of a patient with cutaneous sweat gland carcinoma with local recurrence and metastasis to the lung that was treated with surgical resection therapy and chemotherapy.

Distal Bone Metastasis From Primary Rectal Cancer: A Case Report.

Distal bone metastases from rectal cancer are uncommon. Our case report is from a patient with rectal carcinoma who presented with symptomatic middle finger metastases, and we describe the clinical characteristics of this presentation and the treatment provided. Metastases in bone tissues are a sign of a grave prognostic outcome due to the association of this with advanced terminal disease.
