[Enzyme activities and substrate levels of carbohydrate metabolism in proliferating and suberin synthesizing potato tuber cells].

Planta

Lange H, Kahl G, Rosenstock G.
PMID: 24499978
Planta. 1970 Mar;91(1):18-31. doi: 10.1007/BF00390162.

Isolation of tissue fragments from the potato tuber can initiate either periderm formation including suberin synthesis or cell proliferation without cicatrization effects. TCA-cycle activity has been shown to develop only in causal correlation with suberin synthesis (Lange, 1970). Biochemical...

Cell reports

Daneshmandi S, Cassel T, Lin P, Higashi RM, Wulf GM, Boussiotis VA, Fan TW, Seth P.
PMID: 33691103
Cell Rep. 2021 Mar 09;34(10):108831. doi: 10.1016/j.celrep.2021.108831.

Although T cell expansion depends on glycolysis, T effector cell differentiation requires signaling via the production of reactive oxygen species (ROS). Because the pentose phosphate pathway (PPP) regulates ROS by generating nicotinamide adenine dinucleotide phosphate (NADPH), we examined how...

PMID: 33498665
Biology (Basel). 2021 Jan 23;10(2). doi: 10.3390/biology10020085.

The pentose phosphate pathway (PPP) plays an essential role in the metabolism of breast cancer cells for the management of oxidative stress and the synthesis of nucleotides. 6-phosphogluconate dehydrogenase (6PGD) is one of the key enzymes of the oxidative...

Frontiers in plant science

Li C, Li K, Zheng M, Liu X, Ding X, Gai J, Yang S.
PMID: 34484268
Front Plant Sci. 2021 Aug 13;12:704983. doi: 10.3389/fpls.2021.704983. eCollection 2021.

Phosphorus plays an important role in plant growth and development, and is an important limiting factor for crop yield. Although previous studies have shown that 6-phosphogluconate dehydrogenase (6PGDH) plays an important role in plant resistance to adversity, its response...

Discrimination of some African Armillaria species by isozyme electrophoretic analysis.

The New phytologist

Agustian A, Mohammed C, Guillaumin JJ, Botton B.

New Phytol. 1994 Sep;128(1):135-143. doi: 10.1111/j.1469-8137.1994.tb03996.x.

Ten Armillaria isolates, collected from various host plants and widespread geographical origins in tropical Africa, were cultivated on orange fragments in the presence of water and ran different culture media in order to optimize enzyme and mycelial cord production....

Complementary analyses of the transcriptome and iTRAQ proteome revealed mechanism of ethylene dependent salt response in bread wheat (Triticum aestivum L.).

Food chemistry

Ma Q, Shi C, Su C, Liu Y.
PMID: 32387982
Food Chem. 2020 Apr 20;325:126866. doi: 10.1016/j.foodchem.2020.126866. Epub 2020 Apr 20.

In order to clarify the ethylene dependent salt response mechanism in wheat, 2-week-old wheat seedlings of cultivar 'Qingmai 6' treated with water, sodium chloride (NaCl), NaCl and ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC), and NaCl and ethylene signaling inhibitor 1-methylcyclopropene...

The Plasma Proteome Fingerprint Associated With Circulating Carotenoids And Retinol In Older Adults.

The Journal of nutrition

Yamaguchi Y, Zampino M, Tanaka T, Bandinelli S, Moaddel R, Fantoni G, Candia J, Ferrucci L, Semba RD.
PMID: 34550359
J Nutr. 2021 Sep 22; doi: 10.1093/jn/nxab340. Epub 2021 Sep 22.

BACKGROUND: Although diets rich in carotenoids are associated with reduced risk of cardiovascular disease, age-related macular degeneration, disability, and other adverse aging outcomes, the underlying biological mechanisms are not fully elucidated.OBJECTIVES: To characterize the plasma proteome fingerprint associated with...

Phospholipase C signal mediated the glucose-induced changes of glucose absorption and lipid accumulation in the intestinal epithelial cells of yellow catfish .

The British journal of nutrition

Zhao T, Yang SB, Xu YC, Chen GH, Xu YH, Luo Z.
PMID: 33504374
Br J Nutr. 2021 Dec 14;126(11):1601-1610. doi: 10.1017/S0007114521000350. Epub 2021 Jan 28.

In present study, we explored the effects and the underlying mechanisms of phospholipase C (PLC) mediating glucose-induced changes in intestinal glucose transport and lipid metabolism by using U-73122 (a PLC inhibitor). We found that glucose incubation activated the PLC...

Enzymatic Evidence for a Complete Oxidative Pentose Phosphate Pathway in Chloroplasts and an Incomplete Pathway in the Cytosol of Spinach Leaves.

Plant physiology

Schnarrenberger C, Flechner A, Martin W.
PMID: 12228497
Plant Physiol. 1995 Jun;108(2):609-614. doi: 10.1104/pp.108.2.609.

The intracellular localization of transaldolase, transketolase, ribose-5-phosphate isomerase, and ribulose-5-phosphate epimerase was reexamined in spinach (Spinacia oleracea L.) leaves. We found highly predominant if not exclusive localization of these enzyme activities in chloroplasts isolated by isopyknic centrifugation in sucrose...
