Abstract
BACKGROUND Sesamol is a natural antioxidant known for its potent antioxidant and free radical scavenging properties. This study aimed to explore the therapeutic effects and underlying mechanisms of sesamol in the development of renal ischemia-reperfusion injury (IRI) in mice. METHODS C57BL/6J wild-type mice were divided into 3 groups: IR group, treated with normal saline after undergoing the IRI procedure; Sesamol + IR group, treated with 30 mg/kg/d of sesamol after the IRI procedure; and Sham group, treated with normal saline but not subjected to the IRI process. Renal IRI was induced by performing a right kidney nephrectomy and subjecting the left kidney to 30-minute ischemia, followed by 24-hour reperfusion. Kidney tissues and serum were collected 24 hours post-IRI to assess the impact of sesamol on renal function after IRI. Serum creatinine and blood urea nitrogen levels were assessed, and renal cell apoptosis was detected through terminal deoxynucleotidyl transferase dUTP nick-end labeling staining. The levels of interleukin 1β and interleukin 18 in kidney tissues, as well as indicators of oxidative stress, were also measured. Furthermore, Nrf2-deficient mice were used to examine the protective function of the nuclear factor erythroid 2-related factor 2 (Nrf2)/hemeoxygenase-1 (HO-1) and NAD(P)H dehydrogenase quinone 1 (NQO1) signaling pathways induced by sesamol, as determined by western blot assay. RESULTS Sesamol demonstrated significant improvement in renal function, along with reductions in renal tubular injury, cell necrosis, and apoptosis in mice. It also effectively lowered key inflammatory mediator levels. Sesamol exhibited antioxidant properties by reducing malondialdehyde levels and enhancing superoxide dismutase activities 24 hours after IRI. Western blot assay revealed increased Nrf2, HO-1, and NQO-1 protein levels with sesamol treatment. Notably, Nrf2-deficient mice did not exhibit the beneficial effects of sesamol. CONCLUSIONS This study demonstrates that sesamol effectively alleviates renal IRI by enhancing antioxidant defenses and reducing inflammation potentially through the Nrf2/HO-1 and NQO1 signaling pathways.

Abstract
The TGF-β1/Smad3-signaling pathway and gender differences were investigated in alcoholic liver fibrosis. Mice were divided into female normal, female model, male normal, and male model groups. Liver injury and fibrosis were assessed using histopathology and serology. Western blotting was performed to analyze the expression of relevant factors. HSC-T6 cells were divided into estradiol + saline, estradiol + ethanol, testosterone + saline, and testosterone + ethanol groups, and similar assessments were conducted in vitro. Compared with the female model group, the male model group exhibited significantly increased GPT, GOT, TNF-α, IL-6, and testosterone levels, fibrosis rate, and TGF-β1, Smad3, and PCNA expression, and significantly decreased estradiol levels and Caspase-3 expression. The apoptosis rate was higher in the estradiol + ethanol group than in the testosterone + ethanol group, although the testosterone + ethanol group exhibited significantly increased TNF-α, IL-6, Collagen-I, α-SMA, TGF-β1, Smad3, and PCNA expression, and significantly decreased Caspase-3 expression. Alcoholic liver fibrosis showed significant gender differences associated with the TGF-β1/Smad3-signaling pathway.

Abstract
Sesamol (SM), a well-known component isolated from sesame seeds (Sesamum indicum), used in traditional medicines in treating numerous ailments. However, numerous molecular investigations revealed the various mechanisms behind its activity, emphasizing its antiproliferative, anti-inflammatory, and apoptosis-inducing properties, preventing cancer cell spread to distant organs. In several cells derived from various malignant tissues, SM-regulated signal transduction pathways and cellular targets have been identified. This review paper comprehensively describes the anticancer properties of SM and SM-viable anticancer drugs. Additionally, the interactions of this natural substance with standard anticancer drugs are examined, and the benefits of using nanotechnology in SM applications are explored. This makes SM a prime example of how ethnopharmacological knowledge can be applied to the development of contemporary drugs.

Abstract
Liver fibrosis is caused by chronic liver injury. There are limited treatments for it, and the pathogenesis is unclear. Therefore, there is an urgent need to explore the pathogenesis of liver fibrosis, and to try to identify new potential therapeutic targets. For this study we used the carbon tetrachloride abdominal injection induced liver fibrosis animal model in mice. Primary hepatic stellate cell isolation was performed by a density-gradient separation method, and this was followed by immunofluorescence stain analyses. Signal pathway analysis was performed by dual-luciferase reporter assay and western blotting. Our results showed that RUNX1 was upregulated in cirrhotic liver tissues compared with normal liver tissues. Besides, overexpression of RUNX1 caused more severe liver fibrosis lesions than control group under CCl4 -induced conditions. Moreover, α-SMA expression in the RUNX1 overexpression group was significantly higher than in the control group. Interestingly, we found that RUNX1 could promote the activation of TGF-β/Smads in a dual-luciferase reporter assay. Thus we demonstrated that RUNX1 could be considered as a new regulator of hepatic fibrosis by activating TGF-β/Smads signalling. Based on this, we concluded that RUNX1 may be developed as a new therapeutic target in the treatment of liver fibrosis in the future. In addition, this study also provides a new insight about the aetiology of liver fibrosis.

Abstract
Various therapeutic approaches are conducted for regression of liver fibrosis and prevent possible further carcinogenic transformation. This study was aimed to assess the prospective therapeutic potential of bromelain against thioacetamide (TAA)-induced liver fibrosis using in-vitro and in vivo approaches. In vitro study, HSC-T6 cell line was used to evaluate the effect of bromelain on HSC-T6 cell viability and apoptosis. In vivo, Rats were treated by TAA for 6 weeks for induction of hepatic fibrosis followed by post treatment by different doses of bromelain and silymarin for further 4 weeks to assess the regression of hepatic fibrosis. The in-vitro findings indicated that bromelain hindered the proliferation of HSCs in concentration dependent manner compared with the untreated cells. The in vivo study revealed that treatment of TAA fibrotic rats with different doses of bromelain and silymarin induced a significant restoration in liver function biomarkers, attenuation of oxidative stress, upregulation of total antioxidant capacity and thereby decline of fibrotic biomarkers and improving histopathological and immunohistochemical changes. In conclusion, This study indicates that bromelain can regress TAA induced hepatic fibrosis in rats via inhibiting HSCs activation, α-SMA expression and the ECM deposition in hepatic tissue in addition to its antioxidants pathway, these findings prove the promising therapeutic potential of bromelain as a novel therapeutic approach for chronic hepatic fibrotic diseases.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is one of the most common chronic liver diseases worldwide. The etiology of NAFLD is highly heterogeneous, which occurs and develops under the joint action of metabolism, inflammation, genetics, environment, and gut microbiota. At present, the principal therapeutic modalities targeting NAFLD are lifestyle interventions such as weight loss through diet and exercise. At present, there is no established therapy for the treatment of NAFLD, and many therapies are associated with a variety of side effects. A great number of in vitro and in vivo experiments have indicated that there are many natural foods that have therapeutic potential for NAFLD. This review summarizes the natural foods and their mechanisms that were found in recent years, furthermore, provides further information relevant to the treatment of NAFLD.
