Abstract
The kingdom of plants as a "green biofabric" of valuable bioactive molecules has long been used in many ailments. Currently, extracts and pure compounds of plant origin are used to aid in pigmentation skin problems by influencing the process of melanogenesis. Melanin is a very important pigment that protects human skin against ultraviolet radiation and oxidative stress. It is produced by a complex process called melanogenesis. However, disturbances in the melanogenesis mechanism may increase or decrease the level of melanin and generate essential skin problems, such as hyperpigmentation and hypopigmentation. Accordingly, inhibitors or activators of pigment formation are desirable for medical and cosmetic industry. Such properties may be exhibited by molecules of plant origin. Therefore, that literature review presents reports on plant extracts, pure compounds and compositions that may modulate melanin production in living organisms. The potential of plants in the therapy of pigmentation disorders has been highlighted.

Fancd2os Reduces Testosterone Production by Inhibiting Steroidogenic Enzymes and Promoting Cellular Apoptosis in Murine Testicular Leydig Cells. Endocrinol Metab (Seoul) 2022; 37:533-546.

Abstract
BACKGRUOUND It is well-established that serum testosterone in men decreases with age, yet the underlying mechanism of this change remains elusive. METHODS The expression patterns of Fancd2 opposite-strand (Fancd2os) in BALB/c male mice and testicular tissue derived cell lines (GC-1, GC-2, TM3, and TM4) were assessed using real-time polymerase chain reaction (RT-PCR), Western blot and immunofluorescence. The Fancd2os-overexpressing or knockdown TM3 cells were constructed by infecting them with lentivirus particles and were used to evaluated the function of Fancd2os. The testosterone production was measured using enzyme linked immunosorbent assay (ELISA) and the steroidogenic enzymes such as steroidogenic acute regulatory protein (StAR), P450 cholesterol side-chain cleavage (P450scc), and 3β-hydroxysteroid dehydrogenase (3β-HSD) were analysed using RT-PCR. The apoptosis of TM3 cells induced by ultraviolet light or testicular tissues was detected using flow cytometry, Western blot or dUTP-biotin nick end labeling (TUNEL) assays. Pearson correlation analysis was used to assess the correlation between the Fancd2os expression and TUNEL-positive staining in mouse testicular Leydig cells. RESULTS The Fancd2os protein was predominantly expressed in mouse testicular Leydig cells and its expression increased with age. Fancd2os overexpression inhibited testosterone levels in TM3 Leydig cells, whereas knockdown of Fancd2os elevated testosterone production. Fancd2os overexpression downregulated the levels of StAR, P450scc and 3β-HSD, while Fancd2os knockdown reversed this effect. Fancd2os overexpression promoted ultraviolet light-induced apoptosis of TM3 cells. In contrast, Fancd2os knockdown restrained apoptosis in TM3 cells. In vivo assays revealed that higher Fancd2os levels and mouse age were associated with increased apoptosis in Leydig cells and decreased serum testosterone levels. Pearson correlation analysis exhibited a strong positive correlation between the expression of Fancd2os and TUNEL-positive staining in mouse testicular Leydig cells. CONCLUSION Our findings suggest that Fancd2os regulates testosterone synthesis via both steroidogenic enzymes and the apoptotic pathway.

Metabolic study of ginsenoside Rg3 and glimepiride in type 2 diabetic rats by liquid chromatography coupled with quadrupole-Orbitrap mass spectrometry. RAPID COMMUNICATIONS IN MASS SPECTROMETRY : RCM 2021; 35:e9083. [PMID: 33742471 DOI: 10.1002/rcm.9083] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/03/2021] [Revised: 03/15/2021] [Accepted: 03/15/2021] [Indexed: 06/12/2023]
Abstract
RATIONALE Ginsenoside Rg3 and glimepiride have been applied to treat type 2 diabetes (T2DM) because of their good hypoglycemic effects. In this study, the effects of ginsenoside Rg3 acting synergistically with glimepiride were investigated in liver microsomes from rats with type 2 diabetes. METHODS An in vitro incubation system with normal rat liver microsomes (RLM) and type 2 diabetic rat liver microsomes (TRLM) was developed. The system also included two experimental groups consisting of RLM and TRLM pretreated with ginsenoside Rg3 and glimepiride (named the RLMR and TRLMR groups, respectively). The metabolism in the different groups was analyzed by ultra-performance liquid chromatography coupled with quadrupole-orbitrap mass spectrometry (UPLC/Q-Orbitrap MS). RESULTS The results showed that the concentration of glimepiride increased in RLM and TRLM after treatment with ginsenoside Rg3. Five metabolites (M1-M5) of glimepiride were found, and they were named 3N-hydroxyglimepiride, hydroxyglimepiride, 1,2-epoxy ether-3-hydroxyglimepiride, 1N-hydroxyglimepiride and 1N,2C,S,O,O-epoxy ether-3-hydroxyglimepiride. The metabolite of ginsenoside Rg3 was ginsenoside Rh2. CONCLUSIONS An in vitro incubation system with RLM and TRLM was developed. The system revealed pathways that produce glimepiride metabolites. Ginsenoside Rg3 may inhibit the activity of cytochrome P450 enzymes in vitro. The present study showed that ginsenoside Rg3 and glimepiride may be combined for the treatment of T2DM.
