EVOLUTION AND POPULATION STRUCTURE OF AFRICANIZED HONEY BEES IN BRAZIL: EVIDENCE FROM SPATIAL ANALYSIS OF MORPHOMETRIC DATA.

Evolution; international journal of organic evolution

Diniz-Filho JAF, Malaspina O.
PMID: 28568529
Evolution. 1995 Dec;49(6):1172-1179. doi: 10.1111/j.1558-5646.1995.tb04444.x.

In recent years, studies based on isoenzymatic patterns of geographic variation have revealed that what is usually called the Africanized honey bee does not constitute a single population. Instead, several local populations exist with various degrees of admixture with...

The compartmentation of carboxylating and decarboxylating enzymes in guard cell protoplasts.

Planta

Schnabl H.
PMID: 24301024
Planta. 1981 Jul;152(4):307-13. doi: 10.1007/BF00388254.

Guard cell and mesophyll cell protoplasts of Vicia faba L. were purified and separated into cytoplasmic and plastid fractions by a selective silicone-oil filtration. Before fractionation, the protoplasts were ruptured by a low speed centrifugation through a narrow-aperture nylon...

Novel regulatory roles of omega-3 fatty acids in metabolic pathways: a proteomics approach.

Nutrition & metabolism

Ahmed AA, Balogun KA, Bykova NV, Cheema SK.
PMID: 24438320
Nutr Metab (Lond). 2014 Jan 17;11(1):6. doi: 10.1186/1743-7075-11-6.

BACKGROUND: Omega-3 polyunsaturated fatty acids (n-3 PUFA) have been shown to alleviate the symptoms of metabolic disorders, such as heart disease, diabetes, obesity and insulin resistance. Several putative mechanisms by which n-3 PUFA elicit beneficial health effects have been...

Malate dehydrogenase-2 inhibitor LW6 promotes metabolic adaptations and reduces proliferation and apoptosis in activated human T-cells.

Experimental and therapeutic medicine

Eleftheriadis T, Pissas G, Antoniadi G, Liakopoulos V, Stefanidis I.
PMID: 26640580
Exp Ther Med. 2015 Nov;10(5):1959-1966. doi: 10.3892/etm.2015.2763. Epub 2015 Sep 22.

Activated T cells rely on aerobic glycolysis and glutaminolysis in order to proliferate and differentiate into effector cells. Therefore, intervention in these metabolic pathways inhibits proliferation. The aim of the present study was to evaluate the effects of Krebs'...

Developmental studies on microbodies in wheat leaves : III. On the photocontrol of microbody development.

Planta

Feierabend J.
PMID: 24436025
Planta. 1975 Jan;123(1):63-77. doi: 10.1007/BF00388061.

1. In etiolated wheat (Triticum aestivum L.) leaves, the development of the microbody enzymes catalase, hydroxypyruvate reductase, and glycolate oxidase was specifically stimulated by short treatments of the seedlings with red light, although the increases were less than observed...

The α-Crystallin Domain Containing Genes: Identification, Phylogeny and Expression Profiling in Abiotic Stress, Phytohormone Response and Development in Tomato (Solanum lycopersicum).

Frontiers in plant science

Paul A, Rao S, Mathur S.
PMID: 27066058
Front Plant Sci. 2016 Mar 31;7:426. doi: 10.3389/fpls.2016.00426. eCollection 2016.

The α-crystallin domain (ACD) is an ancient domain conserved among all kingdoms. Plant ACD proteins have roles in abiotic stresses, transcriptional regulation, inhibiting virus movement, and DNA demethylation. An exhaustive in-silico analysis using Hidden Markov Model-based conserved motif search...

Redox stress and hepatic DNA fragmentation induced by diquat in vivo are not accompanied by increased 8-hydroxydeoxyguanosine contents.

Redox report : communications in free radical research

Gupta S, Kleiner HE, Rogers LK, Lau SS, Smith CV.
PMID: 27414769
Redox Rep. 1997 Feb;3(1):31-9. doi: 10.1080/13510002.1997.11747088.

Administration of 0.1 mmol/kg of diquat to Fischer-344 rats causes acute hepatic necrosis by mechanisms that appear to involve increased generation of reactive oxygen species, but the critical targets of the proposed oxidations have not been identified. In the...

The Enzymology of 2-Hydroxyglutarate, 2-Hydroxyglutaramate and 2-Hydroxysuccinamate and Their Relationship to Oncometabolites.

Biology

Hariharan VA, Denton TT, Paraszcszak S, McEvoy K, Jeitner TM, Krasnikov BF, Cooper AJ.
PMID: 28358347
Biology (Basel). 2017 Mar 30;6(2). doi: 10.3390/biology6020024.

Many enzymes make "mistakes". Consequently, repair enzymes have evolved to correct these mistakes. For example, lactate dehydrogenase (LDH) and mitochondrial malate dehydrogenase (mMDH) slowly catalyze the reduction of 2-oxoglutarate (2-OG) to the oncometabolite l-2-hydroxyglutarate (l-2-HG). l-2-HG dehydrogenase corrects this...

Comparative and genetic studies of isozymes in resynthesized and cultivated Brassica napus L., B. campestris L. and B. alboglabra Bailey.

TAG. Theoretical and applied genetics. Theoretische und angewandte Genetik

Chen BY, Heneen WK, Simonsen V.
PMID: 24232800
Theor Appl Genet. 1989 May;77(5):673-9. doi: 10.1007/BF00261242.

Enzyme electrophoresis was used to compare newly resynthesized Brassica napus with its actual parental diploid species, B. campestris and B. alboglabra. Comparisons were also made with cultivated B. napus. Of the eight enzyme systems assayed, four were monomorphic (hexokinase,...

Maize NADP-malate dehydrogenase: cDNA cloning, sequence, and mRNA characterization.

Plant molecular biology

Metzler MC, Rothermel BA, Nelson T.
PMID: 24271204
Plant Mol Biol. 1989 Jun;12(6):713-22. doi: 10.1007/BF00044162.

We report here the isolation, characterization and nucleotide sequence of clones encoding the maize chloroplastic NADP-malate dehydrogenase (NADP-MDH) which functions in the C4 cycle of photosynthesis. A nearly full-length NADP-MDH cDNA clone was isolated using antibodies against the purified...

Preliminary Analysis of Taenia multiceps Metacestode Antigens by Two-Dimensional Electrophoresis.

Increasing anthelmintic resistance and the impact of conventional anthelmintics on the environment, it is important to look for alternative strategies against helminth parasite in sheep. Important lipogenic enzymes like glucose-6-phosphate dehydrogenase (G-6-PDH) and malate dehydrogenase (MDH) show subcellular distribution...
