microRNAs play an important roles in cell growth, differentiation, proliferation and apoptosis. They can function either as tumor suppressors or oncogenes. We found that the overexpression of miR-192 inhibited cell proliferation in A549, H460 and 95D cells, and inhibited tumorigenesis in a nude mouse model. Both caspase-7 and the PARP protein were activated by the overexpression of miR-192, thu...
BACKGROUND The A-kinase anchor proteins (AKAP) are a growing family of scaffolding proteins involved in the occurrence, proliferation, and metastasis of tumors by controlling intracellular signals. In this study, the expression and significance of AKAP4 were analyzed in patients with lung adenocarcinoma and adjacent non-cancerous tissues. METHODS Using reverse transcriptase-polymerase chain r...
Objective(s):According to the prevalence of neoplastic diseases, there is a deep necessity for discovery of novel anticancer drugs in the field of medicinal chemistry. In the current study, a new series ofphenylthiazole derivatives(compounds 4a-4f) was synthesizedand theiranticancer activity was assessed in vitro. Materials and Methods:All synthesized derivatives were evaluated towards three h...
Rab1A expression is associated with malignant phenotypes in several human tumors; however, the role of Rab1A in lung cancer is still unclear. In this study, we attempted to establish the role of Rab1A in major human lung cancer subtypes. Rab1A expression in different histological types of human lung cancer was analyzed in lung cancer tissues with paired adjacent noncancerous tissues and a large...
BACKGROUND Previous reports have suggested that malignant transformations originate from adult stem cells, and may thus express the stem-cell-associated markers. The purpose of this study is to investigate the differential expression and clinical significance of seven stem-cell-associated markers (Bmi1, CD133, CD44, Sox2, Nanog, OCT4 and Msi2) in lung cancer, providing new targets for the diagn...
Childhood bone cancer though rare, has very limited treatment choices, with poor survival rates and often involving amputation. We developed a novel molecule, 2', 4'-dihydroxy-dithion-dibenzoyl-methane and tested it on hepatic, colon, lung and osteoblast cancer cell lines. Thionylation of 2', 4'- dihydroxydibenzoylmethane led to selective targeting of bone cancer cells, stopping their growth an...
Poly(lactic-co-glycolic acid) ([PLGA] 50:50 wt% PLA:PGA) films with a flat surface and with 27 nm, 190 nm, 300 nm, 400 nm, and 520 nm nanopatterns were fabricated using a cast-mold process. The nanopatterns were transferred from self-assembled polystyrene (PS) beads to PLGA films through polydimethylsiloxane (PDMS) molds. The surface features, root-mean- square (RMS) roughness, and wettability ...
objective: due to recent advances in nanotechnology it is now possible to accumulate high atomic-number nanomaterial such as gold nanoparticles (gnps) in cancerous cells and take advantage of their absorbed dose enhancement property as radiosensitizing agents. this study aimed to investigate the absorbed dose enhancement factor due to the presence of pegylated gnps under the irradiation of an m...
