Hyperhomocysteinemia increases the risk of Alzheimer's disease (AD), but the mechanism is elusive. Here, we found that high plasma homocysteine induced by vena caudalis injection for 2 weeks could induce AD-like tau hyperphosphorylation at multiple sites in rat brain hippocampus. Homocysteine inhibited the activity of protein phosphatase 2A (PP2A) with a(More)
The Han Chinese is the largest single ethnic group in the world, consisting of ten Chinese branches. With the exception of the Pinghua branch, the genetic structure of this group has been studied extensively, and Y chromosome and mitochondrial (mt)DNA data have demonstrated a coherent genetic structure of all Han Chinese. It is therefore believed that the(More)
Taq IB polymorphism in the cholesteryl ester transfer protein (CETP) gene has been reported to be associated with serum high-density lipoprotein cholesterol (HDL-C) levels and longevity in several populations, but controversial results also arose probably due to racial/ethnic diversity. Bama is a remote and mountainous county located in the northwest of(More)
Hyperhomocysteinemia and beta-amyloid (Abeta) overproduction are critical etiological and pathological factors in Alzheimer disease, respectively; however, the intrinsic link between them is still missing. Here, we found that Abeta levels increased and amyloid precursor protein (APP) levels simultaneously decreased in hyperhomocysteinemic rats after a(More)
Variants in the Methylenetetrahydrofolate reductase (MTHFR) gene may result in a lowered catalytic activity and associate with subsequent elevated serum homocysteine (Hcy) concentration, abnormal DNA synthesis and methylation, cardiovascular risk, and unhealthy aging. Several investigations on the relationship of MTHFR C677T polymorphism with serum lipid(More)
Cerebral ischemia is one of the most common diseases treated by acupuncture therapeutics. Recent studies indicated that acupuncture treatment by needling the conception and governor vessels had positive effects in promoting neural regeneration in patients after cerebral ischemia injury. Acupuncture intervention could continuously promote the proliferation(More)
Tau hyperphosphorylation and memory deficit are characteristic alterations of Alzheimer's disease (AD), and glycogen synthase kinase-3 (GSK-3) plays a crucial role in these AD-like changes. We have reported that activation of GSK-3 through ventricular injection of wortmannin and GF-109203X (WT/GFX, 100 microM each) induces tau hyperphosphorylation and(More)
The -493G/T polymorphism in the microsomal triglyceride transfer protein (MTP) gene is associated with lower serum low-density lipoprotein cholesterol (LDL-C) and triglyceride (TG) levels and longevity in several populations, but the results are inconsistent in different racial/ethnic groups. The current study was to investigate the plausible association of(More)
Breast cancer is the most common malignancy in women worldwide and pharmaceutical agents have therapeutic and preventive effects in breast cancer. The human epidermal growth factor receptor 2/neu is one of the most important oncogenes in human breast cancer. Prepubertal exposure to endogenous estradiol and a phytoestrogen, genistein (Gen), has been shown to(More)
Utilization of a two-line breeding system via photoperiod-thermo sensitive male sterility has a great potential for hybrid production in wheat (Triticum aestivum L.). 337S is a novel wheat male sterile line sensitive to both short daylength/low temperature and long daylength/high temperature. Five F2 populations derived from the crosses between 337S and(More)
