Abstract: Adipose browning has recently been reported to be a novel therapeutic strategy for obesity. Because the retinoic acid receptor (RAR) is a potential target involved in browning, adapalene (AD), an anti-acne agent with RAR agonism, was examined in detail for its effects on adipose browning and the underlying mechanisms in vitro and in vivo. AD upregulated the expression of adipose browning-related markers in a concentration-dependent manner, promoted mitochondrial biogenesis, increased oxygen consumption rates, and lowered lipid droplet sizes in differentiated 3T3/L1 white adipocytes. Among the three retinoic acid receptors (RARα, RARβ, and RARγ), knockdown of the gene encoding RARβ mitigated AD-induced adipose browning. Similarly, LE135 (a selective RARβ antagonist) attenuated AD action, suggesting that AD promotes adipose browning through RARβ. Sequential phosphorylation of p38 mitogen-activated protein kinase (MAPK) and activating transcription factor 2 (ATF2) was critical for AD-induced adipose browning, based on the observations that either SB203580 (a p38 MAPK inhibitor) or ATF2 siRNA reduced the effects of AD. In vivo browning effects of AD were confirmed in C57BL/6J mice and high-fat diet-induced obese (DIO) mice after oral administration of AD either acutely or chronically. This study identifies new actions of AD as an adipose browning agent and demonstrates that RARβ activation followed by increased phosphorylation of p38 MAPK and ATF2 appears to be a key mechanism of AD action.

The title of the article was 《pH-Induced Changes in the SERS Spectrum of Thiophenol at Gold Electrodes during Cyclic Voltammetry》.Safety of 1,2-Diphenyldisulfane The author mentioned the following in the article:

Thiophenol is a model compound used in the study of self-assembly of arylthiols on Au surfaces. In particular, changes in the surface-enhanced Raman scattering (SERS) spectra of these self-assembled monolayers (SAMs) with a change of conditions were ascribed to, for example, differences in orientation with respect to the surface, protonation state, and electrode potential. Here, potential-induced changes in the SERS spectra of SAMs of thiophenol on electrochem. roughened Au surfaces can be due to local pH changes at the electrode. The changes observed during the potential step and cyclic voltammetry experiments are identical to those induced by acid-base switching experiments in a protic solvent. The potential-dependent spectral changes, assigned earlier to changes in mol. orientation with respect to the surface, can be ascribed to changes in the pH locally at the electrode. The pH at the electrode can change as much as several pH units during electrochem. measurements that reach pos. potentials where oxidation of adventitious H2O can occur. Also, once perturbed by applying pos. potentials, the pH at the electrode takes considerable time to recover to that of the bulk solution The changes in pH even during cyclic voltammetry in organic solvents can be equivalent to the addition of strong acids, such as CF3SO3H, and such effects should be considered in the study of the redox chem. of pH-sensitive redox systems and potential-dependent SERS in particular. In the experiment, the researchers used many compounds, for example, 1,2-Diphenyldisulfane(cas: 882-33-7Safety of 1,2-Diphenyldisulfane)
