Upregulating ANKHD1 in PS19 Mice Reduces Tau Phosphorylation and Mitigates Tau Toxicity-Induced Cognitive Deficits.

Using the fly eye as a model system, we previously demonstrated that upregulation of the fly gene protects against FUS- and Tau-induced photoreceptor degeneration. Building upon this finding, we investigated whether the protective role of is conserved in mammals. To this end, we generated a transgenic mouse line carrying Cre-inducible , the human homolog of Utilizing the TauP301S-PS19 mouse model for Tau-related dementia, we found that expressing ANKHD1 driven by CamK2a-Cre reduced hyperphosphorylated human Tau in 6-month-old mice.

Overexpression of the cassava (Manihot esculenta) PP2C26 gene decreases drought tolerance and abscisic acid responses in transgenic Arabidopsis thaliana.

Background: Cassava (Manihot esculenta Crantz) stands as a pivotal food crop within tropical and subtropical regions. With its inherent drought-tolerant traits, cassava proves to be an ideal candidate for investigating drought tolerance mechanisms in staple crops. Although protein phosphatase 2C (PP2Cs) plays a critical role in drought stress responses in plants, the molecular mechanism of PP2Cs in cassava has yet to be elucidated.

Upregulating ANKHD1 in PS19 mice reduces Tau phosphorylation and mitigates Tau-toxicity-induced cognitive deficits.

Abnormal accumulation of Tau protein in the brain disrupts normal cellular function and leads to neuronal death linked with many neurodegenerative disorders such as Alzheimer's disease. An attractive approach to mitigate Tau-induced neurodegeneration is to enhance the clearance of toxic Tau aggregates. We previously showed that upregulation of the fly gene protects against FUS- and Tau-induced photoreceptor degeneration in fly disease models.

Mask, the Drosophila ankyrin repeat and KH domain-containing protein, affects microtubule stability.

Proper regulation of microtubule (MT) stability and dynamics is vital for essential cellular processes, including axonal transportation and synaptic growth and remodeling in neurons. In the present study, we demonstrate that the Drosophila ankyrin repeat and KH domain-containing protein Mask negatively affects MT stability in both larval muscles and motor neurons. In larval muscles, loss-of-function of mask increases MT polymer length, and in motor neurons, loss of mask function results in overexpansion of the presynaptic terminal at the larval neuromuscular junctions (NMJs).
