Purified natural (n) and recombinant (r) murine (mu) mast cell growth factor (MGF, a c-kit ligand) were evaluated alone and in combination with r human (hu) erythropoietin (Epo), rhu granulocyte-macrophage colony-stimulating factor (rhuGM-CSF), rhuG-CSF, and/or rhuM-CSF for effects in vitro on colony formation by multipotential (colony-forming unit-granulocyte, erythroid, monocyte, megakaryocyt...

Objective: The objective of this study was to determine the DNA damage caused by ceramic bracket (Clear II, SIA Orthodontic Manufacturer Srl, Italy) on human buccal mucosal cells using comet assay and mutagenicity orthodontic bonding system (Transbond XT; 3M Unitek) Ames test. Methods: In study, twenty patients were recruited from Specialist Clinic, Hospital Universiti Sains Malaysia. Buccal ce...

in this paper, we use game theory to describe the emergence of self-organization and consequent pattern formation through communicative cooperation in bacillus subtilis colonies. the emergence of cooperative regime is modelled as an n-player assurance game, with the bacterial colonies as individual players. the game is played iteratively through cooperative communication, and mediated by exchan...

The survival of purified human blood neutrophils and eosinophils was monitored using microwell cultures. Survival was enhanced in cultures containing human or murine colony-stimulating factors (CSFs). The survival of both cell types was enhanced by purified recombinant human granulocyte-macrophage CSF and partially purified preparations of the native molecule, CSF alpha. Neutrophil but not eosi...

Introduction This study aimed to investigate the biological role of microRNA 93 (miR-93), a novel tumor-related miRNA, in human hepatocellular carcinoma (HCC) and elucidate potential molecular mechanisms involved. Material methods Quantitative real-time polymerase chain reaction (qRT-PCR) was conducted determine expression miR-93 HCC tissues cell lines. The log-rank test Kaplan-Meier survival a...

The aim of the present study was to examine the characteristics of bladder transitional cell carcinoma with E-cadherin and N-cadherin double-negative expression. An immunofluorescence assay was used to detect E-cadherin and N-cadherin expression in infiltrative bladder cancer tissues, and immunofluorescence and western blot analysis were used to detect E-cadherin and N-cadherin expression in hu...

Colon cancer constitutes a major challenge all over the world, which has fourth highest incidence and third mortality rate of cancers. Although therapeutic modalities have been improved in recent years, 5 y survival remains low. Oxymatrine is one main active compounds extracted from roots Sophora flavescens was found with effect for colon Recently, microRNAs recognized as type diagnostic progno...

OBJECTIVE To investigate the antitumor effect of SGI-1776 on human ovarian cancer HO-8910 cells and its molecular mechanism. METHODS HO-8910 cells were cultured in vitro, and the proliferation inhibitory effects of SGI- 1776 were determined by MTT assay and colony formation assay. The effect of SGI-1776 on the distribution of cell cycle phase was observed by flow cytometry with propidium iodi...

The aim of this study was to investigate the calcyphosine (CAPS) expression in human colorectal cancer (CRC) and to explore its clinical and prognostic significances. CAPS expression was measured by Western blot, real-time polymerase chain reaction analysis, and immunohistochemistry. The relationships between the CAPS expression levels and the clinicopathological factors were investigated. The ...

These experiments were designed to test whether autocrine/paracrine mechanisms are involved in the growth-promoting action of progesterone (Pg) in the N-nitrosomethylurea-induced rat mammary tumor cultured in vitro in soft agar clonogenic assay. In support of our hypothesis, we observed that conditioned media obtained from Pg-treated tumors (Pg-CM), consistently stimulated colony formation in o...
