Knocking Out TAAR5: A Pathway to Enhanced Neurogenesis and Dopamine Signaling in the Striatum.

The member of trace-amine associated receptor family, TAAR5 receptor was suggested to recognize tertiary amines, mostly in the olfactory system; however, knocking out the receptor TAAR5 in mice showed an enhancing effect on adult neurogenesis and dopamine neurotransmission in the striatum. To estimate the role of the TAAR5, we performed gene expression profiling of striatal samples from TAAR5 knockout (KO) mice and their wild-type littermates. The higher expression of several genes involved in dopaminergic signaling and the downregulation of genes associated with gliogenesis were revealed in TAAR5-KO mice.

Neurotranscriptomic and behavioral effects of ISRIB, and its therapeutic effects in the traumatic brain injury model in zebrafish.

Traumatic brain injury (TBI) is a global medical concern and has a lasting impact on brain activity with high risks of mortality. Current treatments are inadequate for repairing damaged brain cells or correcting cognitive and behavioral disabilities in TBI patients. Mounting evidence links TBI to the activation of the Integrated Stress Response (ISR) signaling in the brain.

Hybridization in the Subtribe Alopecurinae Dumort. (Poaceae) According to Molecular Phylogenetic Analysis: Different Ploidy Level Tells Different Origin of the Groups.

We performed next-generation sequencing of the 18S rDNA-ITS1-5.8S rDNA region along with traditional Sanger sequencing of L, K, F, and ITS1-5.8S rDNA-ITS2 to clarify the hybridization pattern in the subtribe Alopecurinae and in the genus in particular.
