Cell Rep . 2024 Apr; 43(4):114101. PMID: 38613786
Syntaxin-1A (stx1a) repression causes a neurodevelopmental disorder phenotype, low latent inhibition (LI) behavior, by disrupting 5-hydroxytryptaminergic (5-HTergic) systems. Herein, we discovered that lysine acetyltransferase (KAT) 3B increases stx1a neuronal transcription...

Biosci Biotechnol Biochem . 2021 Feb; 85(1):103-107. PMID: 33577646
The biotransformations of capsaicin and dihydrocapsaicin were investigated using cultured plant cells of Phytolacca americana as biocatalysts. Four products, ie 15-hydroxycapsaicin, dihydrocapsaicin, 15-hydroxydihydrocapsaicin, and capsaicin 4-β-glucoside, were isolated from the...
