Tyrosinated tubulin |
Primary neuron |
Tyrosinated tubulin extended into dendritic protrusions. Potassium chloride treatment increases microtubule invasions of dendritic protrusions. |
(Hu et al., 2008) |
Tubulin EB3 |
Primary neuron |
Microtubule invasions of dendritic protrusions. BDNF-induced increase of spine number is blocked by microtubule destabilizer (nocodazole) treatment. |
(Gu et al., 2008) |
EB3 | Primary neuron |
Microtubule invasions of dendritic protrusions. | (Jaworski et al., 2009) |
Tubulin | Hippoca mpal slices |
Electron microscopic analysis shows that there is redistribution of microtubules in dendritic spines following LTP induction. |
(Mitsuyama et al., 2008) |
Acetylated tubulin |
Hippoca mpal slices |
Potassium chloride or NMDA treatment enhances the level of acetylated tubulin. |
(Pandey and Sharma, 2011) |
Tyrosinated tubulin |
Mouse dentate gyrus (contextu al fear condition ing) |
Tyrosinated tubulin increases 0.5-1 h and decreases 8 h following context-shock exposure. Increased tyrosinated tubulin is observed in mice received context only or immediate shock. |
(Uchida et al., 2014) |
Detyrosinate d tubulin |
Mouse dentate gyrus (contextu al fear condition ing) |
Detyrosinated tubulin decreases 0.5-1 h and increases 8 h following context-shock exposure. Decreased detyrosinated tubulin is observed in mice received context only or immediate shock. |
(Uchida et al., 2014) |
Microtubule s |
Mouse hippoca mpus (contextu al fear condition ing) |
Microtubule stabilizer (paclitaxel) injection immediately after contextual fear conditioning reduces long-term memory. Paclitaxel and microtubule destabilizer (nocodazole) injection 8 h after contextual fear conditioning enhances or reduces long-term memory, respectively. |
(Uchida et al., 2014) |
Microtubule s |
Mouse hippoca mpus (contextu al fear condition ing) |
Microtubule turnover is changed following contextual fear conditioning. Nocodazole injection reduces contextual fear memory and spine number. |
(Fanara et al., 2010) |
Microtubule s |
Mouse (Y maze) |
Microtubule stabilizer (epothilone D) treatment rescues deficits in axonal microtubule density and spatial learning observed in aged PS19 mice. |
(Zhang et al., 2012) |
Microtubule s |
Mouse (Morris water maze) |
Paclitaxel treatment leads to reduced microtubule dynamics and deficits in spatial learning. |
