1. Blood mRNA Expression Profiles of Autophagy, Apoptosis, and Hypoxia Markers on Blood Cardioplegia and Custodiol Cardioplegia Groups
Abstract Introduction: Blood cardioplegia (BC) and Custodiol cardioplegia (CC) have been used for a long time in open heart surgery and are highly effective solutions. The most controversial issue among these two is whether there is any difference between them regarding myocardial damage after ischemia surgery. In this study, autophagy, apoptosis, and hypox

2. Oxiracetam ameliorates cognitive deficits in vascular dementia rats by regulating the expression of neuronal apoptosis/autophagy-related genes associated with the activation of the Akt/mTOR signaling pathway
Oxiracetam (ORC) is a commonly used nootropic drug for improving cognition and memory impairments. The therapeutic effect and underlying mechanism of ORC in vascular dementia (VaD) treatment remain unknown. In this study, 3-month-old male Sprague-Dawley rats with permanent bilateral common carotid artery occlusion-induced VaD were treated orally with low (10

3. Kaempferol suppresses human gastric cancer SNU-216 cell proliferation, promotes cell autophagy, but has no influence on cell apoptosis
Gastric cancer remains a serious threat to human health worldwide. Kaempferol is a plant-derived flavonoid compound with a wide range of pharmacological activities. This study aimed to investigate the effects of kaempferol on gastric cancer SNU-216 cell proliferation, apoptosis, and autophagy, as well as underlying potential mechanisms. Viability, proliferat

4. Protection against neurotoxicity by an autophagic mechanism
The objective of the present study was to investigate the effects of 3-n-butylphthalide (NBP) on a 1-methyl-4-phenylpyridinium (MPP+)-induced cellular model of Parkinson’s disease (PD) and to illustrate the potential mechanism of autophagy in this process. For this purpose, rat PC12 pheochromocytoma cells were treated with MPP+ (1 mM) for 24 h following pr

5. Expressão da proteína associada a microtúbulo-2 (MAP-2) no córtex motor primário e recuperação motora após o aprendizado de diferentes tarefas em ratos submetidos à hemorragia intracerebral
As principais incapacidades funcionais que se observam após o Acidente Vascular Encefálico (AVE), sob o ponto de vista clínico, decorrem da hemiparesia, da incoordenação, da hipertonia espástica dos membros superior e inferior contralaterais à lesão e da fraqueza ipsilateral e contralateral ao hemisfério lesado. Evidências sugerem que o aprendizado

6. Cyclic AMP-dependent endogenous phosphorylation of a microtubule-associated protein.
Microtubules prepared from chick brain homogenates by successive cycles of assembly-disassembly were found to contain two high-molecular-weight proteins, designated microtubule-associated protein1 and microtubule-associated protein2. Microtubule-associated protein2 (apparent molecular weight 300,000 by sodium dodecyl sulfate-polyacrylamide gel electrophoresi

7. Plant-Specific Microtubule-Associated Protein SPIRAL2 Is Required for Anisotropic Growth in Arabidopsis1
In diffusely growing plant cells, cortical microtubules play an important role in regulating the direction of cell expansion. Arabidopsis (Arabidopsis thaliana) spiral2 (spr2) mutant is defective in directional cell elongation and exhibits right-handed helical growth in longitudinally expanding organs such as root, hypocotyl, stem, petiole, and petal. The gr

8. Mapmodulin: A possible modulator of the interaction of microtubule-associated proteins with microtubules
We have purified and characterized a 31-kDa protein named mapmodulin that binds to the microtubule-associated proteins (MAPs) MAP2, MAP4, and tau. Mapmodulin binds free MAPs in strong preference to microtubule-associated MAPs, and appears to do so via the MAP’s tubulin-binding domain. Mapmodulin inhibits the initial rate of MAP2 binding to microtubules, a

9. Microtubule-associated protein MAP2 preferentially binds to a dA/dT sequence present in mouse satellite DNA.
Microtubule-associated protein MAP2 binds to the Sau96.1 restriction monomer fragment of mouse satellite DNA. This fragment is also present in a lower proportion in bulk DNA. The digestion of MAP2-Sau96.1 fragment complex by DNase results in the protection of certain nucleotide sequences. The sequence poly(dA)4/poly(dT)4 is mainly protected against DNase dig

10. 2′,3′-Cyclic nucleotide 3′-phosphodiesterase: A membrane-bound, microtubule-associated protein and membrane anchor for tubulin
2′,3′-Cyclic nucleotide-3′-phosphodiesterase (CNP) is firmly associated with tubulin from brain tissue and FRTL-5 thyroid cells as demonstrated by copolymerization with microtubules through several warm/cold cycles, the presence of CNP activity in purified tubulin preparations, and identical behavior during various extraction procedures. CNP acts as a

11. Phosphorylation of the regulatory subunit of type II beta cAMP-dependent protein kinase by cyclin B/p34cdc2 kinase impairs its binding to microtubule-associated protein 2.
Subcellular localization of type II cAMP-dependent protein kinase is determined by the interactions of the regulatory subunit (RII) with specific RII-anchoring proteins. By using truncated NH2-terminal RII beta fusion proteins expressed in Escherichia coli and the mitotic protein kinase p34cdc2 isolated from HeLa cells or starfish oocytes, we investigated th

12. Low molecular weight microtubule-associated proteins are light chains of microtubule-associated protein 1 (MAP 1).
Microtubule-associated protein 1 (MAP 1; Mr = 350,000) was analyzed by column chromatography of microtubule protein obtained from calf brain gray and white matter. Two low molecular weight proteins (LMW MAPs; Mr 28,000 and 30,000) were found to cochromatograph with MAP 1 under all conditions examined. MAP 1 and the LMW MAPs were purified from calf brain whit
