Chemoprotective effect of atorvastatin against benzo(a)pyrene-induced lung cancer via the inhibition of oxidative stress and inflammatory parameters.

Background: Lung cancer affects approximately 9% of women and 17% of men worldwide, and has a mortality rate of 17%. Previously published studies have suggested that oxidative stress expansion can lead to lung cancer. The aim of the current study was to analyze the possible inhibitory pathway of atorvastatin against lung cancer cells in an model.

Knockdown of POLE2 expression suppresses lung adenocarcinoma cell malignant phenotypes in vitro.

In the present study, we profiled β‑elemene‑regulated gene expression and investigated the effects of the silencing of the DNA polymerase epsilon 2, accessory subunit (POLE2) in lung cancer cells. Differently expressed genes were profiled in A549 cells incubated in the presence or absence of β‑elemene by Affymetrix Human Gene Expression Array. POLE2 shRNA was then constructed to knock down POLE2 expression.

Prolonged Breastfeeding Is Associated With Lower Risk Of Severe Hand, Foot And Mouth Disease In Chinese Children.

To assess whether breastfeeding duration can affect risk of severe hand, foot and mouth disease (HFMD) later in childhood, we retrospectively analyzed demographic, environmental and breastfeeding data on 603 children with severe HFMD and 1036 children with mild HFMD. Multivariate analysis showed that breastfeeding for 6-12 months significantly reduced the risk of severe HFMD, as did breastfeeding for >12 months.

PGRN induces impaired insulin sensitivity and defective autophagy in hepatic insulin resistance.

Progranulin (PGRN) has recently emerged as an important regulator for glucose metabolism and insulin sensitivity. However, the underlying mechanisms of PGRN in the regulation of insulin sensitivity and autophagy remain elusive. In this study, we aimed to address the direct effects of PGRN in vivo and to evaluate the potential interaction of impaired insulin sensitivity and autophagic disorders in hepatic insulin resistance.

Selective colorectal cancer cell lysates enhance the immune function of mature dendritic cells in vitro.

The aim of the present study was to determine the most effective antigen with which to mature dendritic cells (DCs). The immune function of DCs loaded with lysates from three different colorectal cancer cell lines was compared. DCs were induced using granulocyte macrophage colony‑stimulating factor, interleukin (IL)‑4 and tumor necrosis factor-α from the peripheral blood mononuclear cells of patients with colorectal cancer, and loaded with lysates from Colo320, SW480 and SW620 colorectal cancer cell lines, respectively.

DNA repair gene XRCC3 Thr241Met polymorphism and susceptibility to glioma: A case-control study.

The DNA repair gene, X-ray repair cross-complementing group 3 (XRCC3) Thr241Met polymorphism may be associated with a susceptibility to glioma. The present study aimed to investigate the association between the XRCC3 Thr241Met polymorphism and the potential susceptibility to gliomas. A hospital-based case-control study was conducted, which included a total of 886 patients with glioma and 886 healthy control subjects.

Prognostic significance of the epithelial-to-mesenchymal transition markers e-cadherin, vimentin and twist in bladder cancer.

Objective: The goal of this study was to utilize long-term patient follow-up to determine whether epithelial-to-mesenchymal transition (EMT)-related markers can predict bladder cancer patient survival and progression of disease.

Materials And Methods: This study included 121 patients with bladder cancer. Sixty-four of these patients presented with non-muscle invasive (NMI, stage T1) bladder cancer and 57 with muscle invasive (MI, stage T2, T3).

Specific survivin dual fluorescence resonance energy transfer molecular beacons for detection of human bladder cancer cells.

Aim: Survivin molecular beacons can be used to detect bladder cancer cells in urine samples non-invasively. The aim of this study is to improve the specificity of detection of bladder cancer cells using survivin dual fluorescence resonance energy transfer molecular beacons (FRET MBs) that have fluorophores forming one donor-acceptor pair.

Methods: Survivin-targeting dual fluorescence resonance energy transfer molecular beacons with unique target sequences were designed, which had no overlap with the other genes in the apoptosis inhibitor protein family.

Involvement of CD147 isoform‑4 in the proliferation of SiHa cells: a possible molecular mechanism of cervical cancer.

CD147, a multifunction glycoprotein of the immuno-globulin family, is associated with many types of tumors, and the overexpression of CD147 can enhance malignancy. However, the role of CD147 in cervical cancer remains unclear. In the present study, cervical cancer cells were found to express much more CD147 protein and isoform‑4 than normal cervical cells (P<0.
