Laird et al. (1987) hypothesized that there are at least four cis-acting alleles or ‘chromosome states’ at Xq27 that increasingly delay replication at this chromosomal area resulting in its increasing fragility in vitro. When on the inactive×chromosome, the proposed third (‘mutated’) allele can permanently block reactivation of its cis Xq27 area as the(More)
Our previous study demonstrated that cystathionine beta synthase (CBS) is highly expressed in the cumulus-oocyte complex during ovulation. However, the role of CBS during oocyte maturation remains uncertain. In this study, a small-interfering (si) RNA interference (siRNA) approach was used to investigate the potential role of CBS during oocyte maturation.(More)
OBJECTIVE To investigate the expression of Abl-interacting protein 1 (ABI1) in normal gastric mucosal cell line GES-1 and gastric cancer cell line AGS, and the effects of ABI1 gene overexpression upon the proliferation of human gastric cancer cell AGS in vitro. METHODS Firstly the ABI1 expression in GES-1 and AGS cells were identified by(More)
OBJECTIVE To screen the candidate human chromosome 21 (HC21) genes related to mental retardation (MR). METHODS The expression of 127 known HC21 genes in the cerebral cortex specimen of a DS fetus and the specimen of a non-DS fetus induced due to maternal disease was detected with Affymetrix U133A gene chip. Semi-quantitative RT-PCR and reverse Northern(More)
BACKGROUND In vitro fertilization (IVF) researches have suggested that cystathionine beta synthase (CBS) is involved in oocyte development. However, little is known about the regional and cellular expression patterns of CBS in the ovary. The purpose of this study was to analyze the localization of CBS in mice ovaries and to investigate the expression(More)
Degenerative lumbar spinal stenosis (DLSS) has become increasingly common and is characterized by multilevel disc herniation and lumbar spondylolisthesis, which are difficult to treat. The current study aimed to evaluate the short-term clinical outcomes and value of the combined use of microendoscopic discectomy (MED) and minimally invasive transforaminal(More)
OBJECTIVE To explore the effects of receptor interacting protein (RIP) 140 gene overexpression upon the in vitro proliferation, apoptosis, invasion and migration of microglioma cells. METHODS The BV-2 RIP140 overexpression model (BV-2-1) was constructed by Lipofection and G418 selection, then validated by real-time PCR and Western blotting. The(More)
Sepsis is a systemic inflammatory response resulting from the excessive production of pro-inflammatory cytokines, including tumor necrosis factor (TNF)‑α. Sirtuin 1 (SirT1) actively deacetylates histone proteins, and facilitates chromatin compaction and gene silencing. In the present study, a cell model of sepsis, comprising lipopolysaccharide(More)
OBJECTIVE To evaluate the feasibility of STR genotyping from trace epithelial cells on fountain pen and to discuss the impact of conservation time on DNA typing. METHODS Seven fountain pens were separately used by each of the 17 volunteers 20 minutes per day for a month and then were preserved on day 1, 3, 5, 7, 14, 21, and 28. DNA was extracted from the(More)
