We evaluated the expression of the Fas receptor gene in Vero cells infected with the Lederle vaccine strain of canine distemper virus using RT-PCR. Vero cells were plated, and after being grown for 24 h in MEM with 5% FBS, 80-90% confluent monolayer cultures were infected with the virus. The cells were harvested at 3, 6, 9, and 15 h post-infection. Uninfected Vero cells were used as a cont...

The purpose of this study was to screen for genes that were differentially expressed between a human gastric carcinoma cell line (HGC-27) and their tumor spheres, using the gene chip technique. The HGC-27 cells and tumor sphere cells were cultured in vitro in a sterile environment. Total RNA was extracted from both samples and purified using a standard TRIzol reagent. Total RNA was then hybridi...

Quantitative polymerase chain reaction (qPCR) analysis is a commonly used method for the study of mRNA expression throughout the field of mesenchymal stem cell (MSC) research. This technology is simple and sensitive; however the results may vary significantly due to the use of various reference genes (RGs) as normalizers. Therefore, the reliable use of RGs is vital for obtaining accurate result...

The present study focuses on the detection of differentially expressed genes in migrating (healing) and nonmigrating (normal) corneal epithelium on agarose gel using a modified procedure of differential display reverse transcriptase-polymerase chain reaction (DDRT-PCR). Rabbit corneal epithelial organ cultures were used to obtain nonmigrating and migrating samples. RNA was extracted using Trizo...

TP53 represents a suitable candidate for a colorectal cancer susceptibility locus. The polymorphism in the p53 72nd codon involves a proline to arginine substitution, leading to changes in gene transcription activity, interaction with other proteins and modulation of apoptosis. Studies evaluating the association between this polymorphism and colorectal cancer (CRC) have shown inconsistent resul...

Background: Leukemia inhibitory factor (LIF) is a 45-56 kDa glycoprotein that has an important role in proliferation and embryo implantation. Its effect on oocyte maturation and how to exert the function remained to be elucidated. Methods: Immature mice superovulated with human menopausal gonadotropin and germinal vesicle (GV) oocytes were obtained from ovary 48 hours after. GV oocytes were cul...

The extraction of intact RNA from oocyte is quite challenging and time-consuming. A standard protocol using commercial RNA extraction kit, yields a low quantity of RNA in oocytes. In the past, several attempts in getting RNA for gene expression study ended up with a few different modified methods. Extraction of high-quality RNA from oocyte is important before further downstream analyses such as...

OBJECTIVE To determine the utility of serum miRNAs as biomarkers for epithelial ovarian cancer. METHODS Twenty-eight patients with histologically confirmed epithelial ovarian cancer were identified from a tissue and serum bank. Serum was collected prior to definitive therapy. Fifteen unmatched, healthy controls were used for comparison. Serum was obtained from all patients. RNA was extracted ...
