Gin A diminished the cellular ATP content and decreased the cell viability of the MTS assay in several breast cancer cell lines. It also showed a delayed G2/M response to breast cancer cells (MCF7 and MDA-MB-231). N-acetylcysteine (NAC), an oxidative stress inhibitor, can revert these responses of antiproliferation and G2/M delay. The oxidative stress and senescence responses of Gin A were further validated by increasing reactive oxygen species, mitochondrial superoxide, and β-galactosidase activity, which were reverted by NAC. Gin A also upregulated senescence-associated gene expressions. In addition to oxidative stress, Gin A also induced DNA damage responses by increasing γH2AX level and foci and generating 8-hydroxyl-2'-deoxyguanosine in breast cancer cells, which were reverted by NAC. Therefore, Gin A promotes antiproliferation and senescence of breast cancer cells induced by oxidative stress.[1]

In this study, we investigated the protective effect of GA on dextran sodium sulfate (DSS)-induced SLI in mice and its mechanism. The SLI was established by adding 4% DSS in the drinking water of mice, and the effects of GA (5, 20 mg/kg, p.o., once a day for 7 days) in hepatic tissues were analyzed. HepG2 cells were induced by lipopolysaccharide (LPS) to detect the effect of GA on ferroptosis and the underlying mechanism. Pathological damage was determined by H&E. Liver parameters (AST and ALT), antioxidant enzyme activities (MDA and SOD), and the level of Fe2+ in the liver were detected by kits. Cytokine levels (TNF-α, IL-1β, and IL-6) and Gpx4 activity in the liver were detected by ELISA. Finally, the activation of nuclear factor erythroid 2-like 2 (Nrf2) was detected to explore the mechanism. The results indicated that GA significantly attenuated DSS-induced hepatic pathological damage, liver parameters, and cytokine levels and increased the antioxidant enzyme activities. Moreover, GA attenuated ferroptosis in DSS-induced liver injury and upregulated Gpx4 expression in DSS-induced mice. Mechanistic experiments revealed that GA activated Nrf2 in mice. Taken together, this study demonstrates that GA can alleviate ferroptosis in SLI in DSS-induced colitis mice, and its protective effects are associated with activating the Nrf2-Gpx4 signaling pathway.

Livers Biochemical Analysis[2]
Briefly, about 40 mg of frozen liver was taken and homogenized by adding 300 μL of PBS, and then, the supernatant was extracted. Then, supernatants were used to determinate the levels of ALT and AST, following the manufacturer’s protocol. Detection of Cytokines and Oxidative Stress[2] The following assays were performed using the above extracted liver protein supernatant. The levels of hepatic TNF-α (EK282/4), IL-1β (EK201B), and IL-6 (EK206/3) in the liver were determined according to the instructions of the ELISA kit. The activities of hepatic GSH (A006-1-2) and MDA (A003-1-2) were determined by a kit. Detection of Fe2+ Release Assay and GPX4 Enzymatic Activity[2] The following assays were performed using the above extracted liver protein supernatant. The supernatants were used to determinate the hepatic Fe2+ release (TC1015) level following the manufacturer’s protocol and the GPX4 enzymatic activity (MM-44846M2) following the manufacturer’s protocol. |

Cell Viability[1]
Viability was assessed using an ATP kit, MTS cell proliferation assay, and trypan blue reagent based on the user manual’s instruction. Cell Cycle Detection[1] To stain DNA, 7-Aminoactinomycin D (7AAD) (1 μg/mL, 30 min, 37 °C) was used in order to determine cell cycle phases. The 7AAD-stained cells were resuspended in PBS to perform flow cytometer. Cell cycle phases were analyzed by FlowJo software version 10. |
| Animal Protocol |
SPF Male C57 mice were purchased from the Experimental Animal Service Center of Guangzhou University of Chinese Medicine (SCXK 2020-0051). The mice were housed at a temperature of 20–24 °C, relative humidity of 55 ± 10%, and a light/dark cycle of 12–12 h. All animal care and experimental studies were approved by the Animal Ethics Committee of Guangzhou University of Chinese Medicine and followed its guidelines.[2]
As described in our previous publication, the SLI mouse model was treated by 7 days of dextran sodium sulfate (DSS; MW, 36 000–50 000) free drinking. As shown in Figure 1B, mice were randomly grouped into an average of 10 mice per group. The groups were set as the control group (Ctrl), 4% DSS group, 4% DSS+5-ASA (50 mg/kg) group, 4% DSS+GA (5 mg/kg) group (GAL), and 4% DSS+GA (20 mg/kg) group (GAH). During DSS treatment, mice in the control were given distilled water, and the rest of the groups were given the corresponding drugs; body weights were assessed daily. The livers were removed, and a portion was cut and soaked in 4% paraformaldehyde for pathology; the remainder was frozen at −80 °C.[2] |
