Ablation of peroxisome proliferator activated receptor (PPAR) alpha, a lipid-activated transcription factor that regulates expression of beta-oxidative genes, results in profound metabolic abnormalities in liver and heart. In the present study we used PPAR alpha knockout (KO) mice to determine whether this transcription factor is essential for regulating(More)
Neurabin I, a neuronal actin-binding protein, binds protein phosphatase 1 (PP1) and p70 ribosomal S6 protein kinase (p70S6K), both proteins implicated in cytoskeletal dynamics. We expressed wild-type and mutant neurabins fused to green fluorescent protein in Cos7, HEK293, and hippocampal neurons. Biochemical and cellular studies showed that an N-terminal(More)
Neurabins are protein phosphatase-1 (PP1) targeting subunits that are highly concentrated in dendritic spines and post-synaptic densities. Immunoprecipitation of neurabin I and neurabin II/spinophilin from rat brain extracts sedimented PP1gamma1 and PP1alpha but not PP1beta. In vitro studies showed that recombinant peptides representing central regions of(More)
The class of Omega glutathione transferases is newly identified with novel structural and functional characteristics. Human GSTO 1-1 (glutathione S-transferase Omega 1) is the first member of the GST Omega class. It was found to play a role in apoptosis and be in association with age-at-onset of AD and PD. In order to improve the understanding of the(More)
Inhibitor-1 (I-1) is a selective inhibitor of protein phosphatase-1 (PP1) and regulates several PP1-dependent signaling pathways, including cardiac contractility and regulation of learning and memory. The human I-1 gene has been spliced to generate two alternative mRNAs, termed I-1alpha and I-1beta, encoding polypeptides that differ from I-1 in their(More)
The aim of the present study was to establish a new method based on Similarity Analysis (SA), Cluster Analysis (CA) and Principal Component Analysis (PCA) to determine the quality of different samples of Poria cocos (Schw.) Wolf obtained from Yunnan, Hubei, Guizhou, Fujian, Henan, Guangxi, Anhui and Sichuan in China. For this purpose 15 samples from the(More)
Bushen‑Yizhi formula (BSYZ), a traditional Chinese medicine formula consisting of six herbs has been reported to possess a neuroprotective effect. The present study aimed to investigate the effects of BSYZ on learning and memory abilities, as well as oxidative stress and neuronal apoptosis in the hippocampus of scopolamine (SCOP)‑induced senescence in mice,(More)
To study the effect of increasing the chain length over C-18 and varying the oxidation level in synthesized N 4,N 9-diacyl spermines on DNA and siRNA formulation, and then to compare their transfection efficiency in cell lines The five novel very long chain N 4,N 9-diacyl polyamines: N 4,N 9-[diarachidoyl, diarachidonoyl, dieicosenoyl, dierucoyl and(More)
To study the efficiency of novel synthetic N 1,N 12-diacyl spermines on DNA and siRNA binding, and to compare their transfection efficiency with viability in cell lines. Five long chain N 1,N 12-diacyl lipopolyamines: N 1,N 12-[didecanoyl, dimyristoyl, dimyristoleoyl, distearoyl and dioleoyl]-1,12-diamino-4,9-diazadodecane were synthesized from the(More)
The plants of the genus Phyllanthus (Euphorbiaceae) have been used as traditional medicinal materials for a long time in China, India, Brazil, and the Southeast Asian countries. They can be used for the treatment of digestive disease, jaundice, and renal calculus. This review discusses the ethnopharmacological, phytochemical, and pharmacological studies of(More)
