1-β-D-Glucosylsphingosine is a glucosylsphingosine, which are deacetylated lysolipid derivatives of glucocerebrosides (Item Nos. 23206 | 23207 | 25850).{41130} They are formed when sphingosines undergo glucosidation by UDP-glucose.{41131} Glucosylsphingosines completely reduce neurite outgrowth and induce death of LA-N-2 cells when used at concentrations of 10 and 50 μM, respectively. They also decrease the activity of glucocerebrosidase in LA-N-2 cells in a concentration-dependent manner. Glucosylsphingosine levels are elevated in patients with Gaucher’s disease, both in the spleen (in types 1, 2, and 3) and brain (types 2 and 3), thus, glucosylsphingosine has been used as a key biomarker of the disease.{41130,41132} This product contains 1-β-D-glucosylsphingosine (d18:1) isolated from bovine buttermilk.[Matreya, LLC.

The tetracycline repressor (TetR) is a transcriptional regulator which normally binds tightly to its palindromic tetO operator DNA, blocking gene expression.{17508} Tet causes the repressor to dissociate from the DNA, allowing transcription to occur. A novel reverse TetR (revTetR) requires tetracycline as a co-repressor to bind tetO and block transcription.{17509,17510} Anhydrotetracycline (hydrochloride) is a powerful effector in both the tetracycline repressor (TetR) and reverse TetR (revTetR) systems, binding the Tet repressor 35-fold more strongly than Tet.{17508,17511} Moreover, anhydrotetracycline poorly binds the 30S ribosomal subunit, compared to Tet,{17512} so it does not act as a general inhibitor of translation and is a poor antibiotic. Perhaps related to this, the concentration of anhydrotetracycline that inhibits eukaryotic cell growth is more than a 1,000-fold above the dose that alters transcription through TetR.{17508}
